Description

The present invention relates to a method for designing an instrument to increase the range of motion of a joint.

As we age, our joints lose flexibility and our bodies become stiffer, but losing flexibility can lead to unexpected injuries. In particular, elderly people who break their legs when they fall or fall are more likely to become bedridden, and it has been reported that becoming bedridden can lead to the progression of dementia. Even if you are not elderly, poor flexibility can lead to unexpected serious accidents. There is also a risk of unexpected injuries such as rupturing the Achilles tendon or injuring muscles during sports. High flexibility can prevent such unexpected accidents, injuries, and disabilities. This flexibility is one of the physical strengths of humans, and refers to the ability of muscles and tendons to stretch. It is considered to be one of the athletic abilities along with muscle strength, explosive power, endurance, and coordination, and is a physical ability that is the basis of basic actions. In other words, high flexibility means that the range of motion of the joints is expanded, allowing for smooth movement. In order to maintain and promote health and be active with peace of mind in the era of 100-year lifespans, it is one of the most important efforts to improve and maintain flexibility, which is the ability to smoothly perform actions, a component of physical strength, as a physical ability that is the basis of basic actions.

For example, Patent Document 1 proposes a stretching aid that has a footboard, a heel stopper protruding from the upper side of the rear end of the footboard, and a support member that supports the footboard at a desired angle in order to improve flexibility. The footboard has a desired number of engagement grooves for angle adjustment formed in parallel at a specified interval in the front-to-rear direction of the footboard on the top surface of the footboard in the width direction of the footboard. The support member has a pair of leg rods of a specified length arranged in parallel with a distance slightly longer than the width of the footboard, a connecting rod that connects both leg rods, an engagement rod that is located on a line connecting both leg rods at the top ends of both leg rods and is formed at a right angle to engage with the grooves, and a support rod that is located below the engagement rod and is fixed horizontally between both leg rods with a distance corresponding to the thickness of the footboard between the engagement rod and the engagement rod.

The stretching aid is designed so that the footboard is inserted between the engaging rod and the support rod of the support member from the tip side, engaging the engaging rod with the engaging groove, and in this state the leg rod is opened toward the front side of the footboard and the footboard is placed on the ground. The footboard is supported by the support rod and fixed in place by the wedge action with the engaging rod, and is stably supported in an inclined position. Therefore, by standing on the footboard and using it in the same way as before, it is said to have the effect of strengthening the Achilles tendon and other excellent stretching effects.

Japanese Patent Application Publication No. 11-299926

However, conventional methods for increasing the range of motion of joints require the use of large-scale equipment and can cause pain or discomfort to the muscles when they are stretched, making them difficult to perform easily and continuously. There is also the problem that if stretching is not performed for a while, flexibility returns to normal. As such, conventional methods for increasing the range of motion of joints have been ineffective or have no prospect of being effective. For this reason, a more effective method is desired.

The present invention was made in consideration of the above problems, and aims to provide an equipment design method for designing equipment that can promote muscle elongation and increase the range of motion of joints.

In order to solve the above problems, the inventors discovered that, among the many Pacinian corpuscles present in the human body, pressing on certain Pacinian corpuscles (specifically, those present in the palm of the hand) promotes muscle elongation, and that this reduction can increase the range of motion of the joints, thus completing the present invention.

The present invention provides a device that can promote muscle elongation and increase the range of motion of joints. Moreover, the present invention has the effect that when the device is used, the muscle elongation effect continues for a certain period of time (e.g., 5 minutes) after use. Furthermore, the present invention has the effect that the device can be designed to suit the user.

The location of the Pacinian corpuscles in the palm of the human hand is roughly the same, but the location varies slightly from person to person and from hand to hand.
The device according to the embodiment is a hand tool to be held in one hand and has a structure in which, when held in the palm of the hand, the Pacinian ball (the contact part 21 of the pressing part 20), which is a protrusion provided on the main body, hits the exact position of the Pacinian corpuscles every time. The device according to the embodiment is also characterized in that the force or pressure can be adjusted so that an appropriate pressure can be applied to maximize the effect of the Pacinian corpuscles (muscle relaxant effect).

(Pacinian Corpuscles)
Pacinian corpuscles are sensory receptors that detect pressure and vibration, and in the hand, as shown in Fig. 30, they are present near the center of the palm on the little finger side (the surface from the wrist to the base of the fingers that is on the inside when the hand is clenched) (A in the figure) and at the tip of the middle finger (B in the figure). Of these, the Pacinian corpuscles according to the present invention are those present in the palm (A in the figure). The device 1 according to the embodiment stimulates the Pacinian corpuscles present near the center of the palm on the little finger side. The present invention aims to reduce pain on the side of a muscle being stretched by applying pressure stimulation to the Pacinian corpuscles.

[First embodiment]
(Configuration of Instrument 1)
The configuration of the device 1 will be described with reference to Figures 1 to 4. The device 1 according to the embodiment is a device for increasing the range of motion of a joint. Specifically, the device aims to promote muscle stretching while reducing pain on the side of the muscle being stretched during muscle stretching, and to increase the range of motion of the joint during exercise, thereby enabling the user to perform exercise more smoothly.

Figure 1(a) is a plan view of the device 1, Figure 1(b) is a right side view of the device 1, Figure 1(c) is a bottom view of the device 1, Figure 1(d) is a rear view of the device 1, and Figure 1(e) is a front view of the device 1. Figure 2 is an enlarged view of Figure 1(b). Figure 3(a) is a plan view of the device 1, and Figure 3(b) is a left side view of the device 1. Figures 4 and 5 are diagrams for explaining the functions of each part of the device 1.

In the following explanation, as shown in FIG. 3, the horizontal direction relative to an imaginary line that is perpendicular to the Y axis and connects the two second stoppers 11B is the X axis, the longitudinal direction of the device 1 is the Y axis, and the horizontal direction relative to an imaginary line that is perpendicular to the Y axis and connects the first recess 12A and the abutment portion 21 is the Z axis.

The instrument 1 is designed so that when the instrument 1 is grasped using the grasping method described below, the contact portion 21 of the instrument 1 comes to a position that comes into contact with the location of the Pacinian corpuscles. The instrument 1 is designed to stimulate the Pacinian corpuscles by pressing the contact surface 21A of the contact portion 21 of the instrument 1 with the gripping force of the little finger and the gripping force of the auxiliary ring finger. The contact portion 21 is spherical in shape so that it can pinpoint and press only the Pacinian corpuscles (it is preferable that the contact portion 21 is shaped so that it does not stimulate anything other than the Pacinian corpuscles (it does not touch or is difficult to touch)).

The device 1 includes a main body 10 that is held by a user, and a pressing part 20 that protrudes from the main body 10 and stimulates the Pacinian corpuscles present in the palm of the user's hand by pressing the Pacinian corpuscles when the main body 10 is held by the user. The pressing part 20 includes an abutment part 21 (Pacinian ball) having an abutment surface 21A that abuts the Pacinian corpuscles, and a connection part 22 that connects the main body 10 and the abutment part 21 by separating from the palm of the user's hand when the main body 10 is held by the user. Here, the abutment part 21 has a shape that can pinpoint press only the Pacinian corpuscles (although the abutment part 21 is ball-shaped in this embodiment, it is sufficient to pinpoint press only the Pacinian corpuscles, and does not prevent it from having any other shape) (it is preferable that the abutment part 21 has a shape that does not stimulate anything other than the Pacinian corpuscles (it does not touch or is difficult to touch).

The main body 10 of the device 1 also includes a first stopper 11A that protrudes from the main body 10 and abuts against the user's little finger when the main body 10 is held by the user, thereby positioning the device 1 within the user's palm. The first stopper 11A restricts upward movement along the Y axis.

The main body 10 of the device 1 also includes a second stopper 11B that protrudes from the main body 10 and is positioned between the user's index finger and middle finger when the main body 10 is held by the user, restricting rotation of the device 1 within the user's palm. The first stopper 11A restricts downward movement along the Y axis.

The main body 10 of the device 1 further includes a third stopper 11C that protrudes from the main body 10 and abuts against the base of the user's thumb when the main body 10 is held by the user, thereby restricting rotation of the device 1 within the user's palm. As shown in FIG. 3, the first stopper 11A restricts downward movement along the Y axis.

As described above, the first to third stoppers 11A to 11C restrict the downward movement of the instrument 1 along the Y axis, and the position of the instrument 1 in the palm of the hand does not move along the Y axis when it is gripped. Furthermore, if the instrument 1 rotates in the palm, the abutment portion 21 will shift from the position of the Pacinian corpuscles. In order for the abutment portion 21 to press the Pacinian corpuscles with the force of the little finger, the instrument 1 must not rotate in the palm. Therefore, as shown in Figure 4, clockwise rotation is restricted by the second stopper 11B, and counterclockwise rotation is restricted by the third stopper 11C, restricting the rotation of the instrument 1 gripped in the palm, and the pressing force of the little finger is reliably transmitted to the Pacinian corpuscles via the instrument 1. In this way, the device 1 is designed so that it will come to the intended position on the palm of the hand (the position where the contact part 21 (Pacinian ball) of the pressing part 20 contacts the Pacinian corpuscles) at three points: the first stopper 11A as the starting point, the second stopper 11B, and the third stopper 11C.

The main body of the device 1 has a first recess 12A for positioning the user's little finger at a position substantially opposite the position where the pressing unit 20 is provided. The main body of the device 1 has a second recess 12B for positioning the user's ring finger adjacent to the first recess 12A. The device 1 of the embodiment is configured so that the pressing unit 20 presses the Pacinian corpuscles with an appropriate force as shown in FIG. 5 by gripping the main body 10 with the user's little finger positioned in the first recess 12A of the main body 10 and the user's ring finger positioned in the second recess 12B.

In the embodiment of the device 1, the pressing portion 20 is spherical. This is because when pressing and stimulating the Pacinian corpuscles, if other sensory receptors around the Pacinian corpuscles are stimulated, they become disturbances and the sensitivity of the pressure stimulus to the Pacinian corpuscles is weakened. By making the contact portion 21 (Pacinian ball) of the pressing portion 20 spherical, the pressure stimulus can be concentrated only on the Pacinian corpuscles, so a predetermined range of space is formed around the contact portion 21 of the ball-shaped pressing portion 20 that applies pressure, and the effect of the present invention is enhanced. In addition, since the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 sinks into the palm by about 1 mm to 15 mm (preferably 3 to 10 mm) to apply appropriate pressure to the Pacinian corpuscles, it is preferable that a space is formed around the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 when the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 sinks into the palm by about 1 mm to 15 mm as shown in FIG. 5 so as not to stimulate sensory receptors other than the Pacinian corpuscles. In addition, as long as a space of a predetermined range is formed around the contact portion 21 of the pressing portion 20 and the pressure stimulus can be concentrated only on the Pacinian corpuscles, the contact portion 21 of the pressing portion 20 does not necessarily have to be spherical in shape.

As described above, it is preferable to apply pinpoint pressure to the Pacinian corpuscles in the palm. This point will be explained in more detail. The palm contains the ulnar nerve. It is understood that in addition to the Pacinian corpuscles, other mechanoreceptors also exist on the ulnar nerve. In this situation, it is preferable that the instrument according to the present invention is designed so that when the instrument is used, the pressure applied to the Pacinian corpuscles in the palm is greater than the pressure applied to the other mechanoreceptors in the palm. From another perspective, it is preferable that a space is formed around the contact portion when the instrument according to the present invention is used. In other words, it is preferable that a region where the instrument does not contact the palm (non-contact region) is formed outside the region where the contact portion contacts the palm (contact region) so as to surround the contact region.

As described above, it is preferable that the pressing unit 20 pinpoint presses the Pacinian corpuscles in the palm. It is preferable that the pressing unit 20 can be directed to target the Pacinian corpuscles in the palm during use, and that the contact unit 21 has a curved surface that bulges toward the Pacinian corpuscles. The curved surface may be spherical or aspherical. The degree of bulging may be determined as appropriate. For example, when the Pacinian corpuscles are to be strongly stimulated, the degree of bulging may be increased, and when the Pacinian corpuscles are to be weakly stimulated, the degree of bulging may be decreased (closer to a flat surface). Furthermore, the pressing unit 20 may be formed of a cylinder. When the pressing unit 20 is formed of a cylinder, the bottom surface of the cylinder becomes the contact unit 21, and the contact unit 21 has a flat shape. The flat surface faces and contacts the Pacinian corpuscles. Furthermore, the pressing unit 20 may be formed of multiple cylinders arranged concentrically with different radii. Regardless of the shape of the pressure unit 20, it is sufficient that it can be directed toward the Pacinian corpuscles in the palm of the hand during use and can concentrate pressure on the Pacinian corpuscles.

(Method of holding the instrument 1)
A method of using (holding) the device 1 will be described with reference to FIGS.
(1) The contact surface 21A of the contact portion 21 (Pacinian ball) of the instrument 1 is aligned with the position of the Pacinian corpuscles (see FIG. 6(a)).
(2) Grip the main body 10 of the main body 1 by placing the little finger against the second stopper 11A, the little finger in the first recess 12A, and the ring finger in the second recess 12B (see FIG. 6(b)).
Since fingers and hands adapt to the shape of the object being grasped, even if the contact portion 21 (Pacinian ball) is aligned with the position of the Pacinian corpuscles, the object can be grasped at the position of the little finger stopper.
(3) The user grips the main body 10 of the main body 1 with his/her middle finger against the second stopper 11B (see FIG. 7(a)).
(4) Grip main body 10 of main body 1 by placing the base of the thumb (webbed area) against third stopper 11C (see FIG. 7(b)).
(5) The position of the instrument 1 in the palm is properly determined by the first to third stoppers 11A to 11C. In other words, the contact surface 21A of the contact portion 21 of the instrument 1 matches the position of the Pacinian corpuscles (see FIG. 7(c)).

As shown in FIG. 3(a), the device 1 is configured to be symmetrical about the Y axis in a plan view, but it does not necessarily have to be configured to be symmetrical about the Y axis in a plan view.

As described above, the device 1 according to the embodiment is a device for increasing the range of motion of a joint. The device 1 includes a main body 10 that is held by a user, and a pressure unit 20 that protrudes from the main body 10 and stimulates the Pacinian corpuscles present in the palm of the user's hand by applying pressure when the main body 10 is held by the user. This allows stretching to be performed while stimulating the Pacinian corpuscles, and the range of motion of the joint can be increased more effectively.

The pressing unit 20 of the device 1 according to this embodiment includes a contact unit 21 having a contact surface that contacts the Pacinian corpuscles, and a connection unit 22 that connects the main body unit 10 to the contact unit by moving away from the palm of the user's hand when the main body unit 10 is held by the user. This makes it possible to press and stimulate only the Pacinian corpuscles, more effectively inducing muscle relaxation and expanding the range of motion of the joints.

The main body 10 of the device 1 according to this embodiment has a first recess 12A for positioning the user's little finger at a position substantially opposite the position where the pressing unit 20 is provided, and is configured so that the pressing unit 20 presses the Pacinian corpuscles by gripping the main body 10 with the user's little finger positioned in the first recess 12A of the main body 10. In this way, the device 1 can be positioned within the palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

The main body 10 of the device 1 according to this embodiment has a second recess 12B adjacent to the first recess 12A for positioning the user's ring finger, and is configured so that the pressing part 20 presses the Pacinian corpuscles when the user grasps the main body 10 with the user's ring finger positioned in the second recess 12B of the main body 10. In this way, the device 1 can be positioned within the user's palm, so that the Pacinian corpuscles can be reliably pressed and stimulated.

The main body 10 of the device 1 according to this embodiment is provided with a first stopper 11A that protrudes from the main body 10 and abuts against the little finger of the user when the main body 10 is held by the user, thereby positioning the device within the palm of the user's hand. In this way, the device 1 can be positioned within the palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

The main body 10 of the device 1 according to this embodiment is provided with a second stopper 11B that protrudes from the main body 10 and is positioned between the index finger and middle finger of the user when the main body 10 is held by the user, restricting the rotation of the device 1 within the palm of the user's hand. In this way, the device 1 can be positioned within the palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

The main body 10 of the device 1 according to this embodiment is provided with a third stopper 11C that protrudes from the main body 10 and abuts against the base of the user's thumb when the main body 10 is held by the user, restricting the rotation of the device within the user's palm. In this way, the device 1 can be positioned within the user's palm, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[Modification of the embodiment]
Fig. 8 is a diagram for explaining the configuration of the instrument 1 according to the modified embodiment. Fig. 8(a) is a diagram showing the instrument 1 according to the modified embodiment separated, and Fig. 8(b) is a diagram showing the instrument 1 according to the modified embodiment assembled. In the above embodiment, the positions of the pressing part 20 and the first to third stoppers 11A to 11C of the instrument 1 are fixed to the main body part 10, but the instrument 1 according to the modified embodiment is configured such that the pressing part 20 and the first to third stoppers 11A to 11C are separable from the main body part 10.

As shown in FIG. 8(a), the device 1 according to the modified embodiment has a main body 10 that can be separated into a first main body 101, a second main body 102, a third main body 103, and a fourth main body 104. The first main body 101 has a recess 101b whose longitudinal direction is parallel to the Y-axis, and the pressing part 20 has a protrusion 20a that slidably engages with the recess 101b. The protrusion 20a of the pressing part 20 slidably engages with the recess 101b of the first main body 101, so that the position of the abutment part 21 (Pacinian ball) of the pressing part 20 can be adjusted parallel to the Y-axis.

The first body 101 is provided with a protrusion 101a whose longitudinal direction is parallel to the Y-axis, and the second body 102 is provided with a recess 102c that slidably engages with the protrusion 101a of the first body 101. The protrusion 101a of the first body 101 slidably engages with the recess 102c of the second body 102, so that the position of the first stopper 11A (little finger stopper) can be adjusted parallel to the Y-axis (note that by adjusting the position of the first stopper 11A (little finger stopper), the position of the abutment portion 21 (Pacinian ball) can also be adjusted).

The second body 102 is provided with a convex portion 102a whose longitudinal direction is parallel to the Y-axis, and the third body 103 is provided with a concave portion 103b that slidably engages with the convex portion 102a of the second body 102. The convex portion 102a of the second body 102 and the concave portion 103b of the third body 103 slidably engage with each other, so that the position of the third stopper 11C (thumb stopper) can be adjusted parallel to the Y-axis.

The second body 102 is provided with a protrusion 102b whose longitudinal direction is parallel to the Y-axis, and the fourth body 104 is provided with a recess 104b that slidably engages with the protrusion 102b of the second body 102. The recess 104b of the fourth body 104 slidably engages with the protrusion 102b of the second body 102, so that the position of the second stopper 11B (middle finger stopper) can be adjusted parallel to the Y-axis.

By configuring it in this way, the positions of the contact portion 21 (Pacinian ball) of the pressing portion 20 and the first to third stoppers 11A to 11C can be adjusted to suit the size and shape of each user's hand, and by holding the device in one hand, the contact portion 21 (Pacinian ball) of the pressing portion 20 can accurately contact the Pacinian corpuscles, applying appropriate pressure.

The function and configuration of the device 1 according to the modified embodiment shown in FIG. 8 is the same as that of the device 1 according to the embodiment described with reference to FIG. 1 to FIG. 7, except that the positions of the contact portion 21 (Pacini ball) of the pressing portion 20 and the first to third stoppers 11A to 11C can be adjusted to suit the size and shape of each user's hand. For this reason, a redundant description of the function and gripping method of the device 1 according to the modified embodiment shown in FIG. 8 will be omitted (for the function and gripping method, see FIG. 4 to FIG. 7 and the corresponding description).

As will be described later in the examples, the effect of the present invention can be achieved if the Pacinian corpuscles can be stimulated by pressure or the like. For this reason, the device does not necessarily have to be shaped to be held in one hand, as in the device 1 according to the embodiment described with reference to Figures 1 to 6, and may be, for example, a clip-shaped device provided with a pressure part that contacts the Pacinian corpuscles by pressing them so as to pinch the palm of the hand. Also, a pressure part having a contact surface that contacts the Pacinian corpuscles may be provided on the inside of the glove. Furthermore, the shape of the device may be, for example, a shape that can be held with both hands (including a rod-like or handle-like shape, a game controller shape, etc.). In this case, it is conceivable to provide two pressure parts 20 in one device, one for the left and right hands.

[Use]
The device according to the present invention is effective for various applications involving muscle elongation, since muscle elongation is promoted. For example, specific applications include devices for improving motor function {for example, muscle elongation training (for example, stretching, yoga, muscle training); track and field (for example, short distance, marathon, long jump); ball games (for example, baseball, golf); ice sports (for example, figure skating, jumping)}, and rehabilitation (for example, lower back pain, frozen shoulder, stiff shoulders). Here, for example, in the case of golf, by using a glove with a Pacinian pressure part on the inside of the glove, it is expected that the correct form will be created and the arm will be raised further. In addition, in the case of figure skating, it is expected that the number of rotations will increase if the palm of the hand is pressed against the Pacinian during practice (including practice until the day of the game, practice on the day of the game, practice just before the game on the day of the game, etc.). The present invention can improve the performance of athletes, and can improve muscle flexibility without pain for ordinary people. In order to further realize the effects of the present invention, it is preferable to continue to press the Pacinian corpuscles for a predetermined period of time (for example, about 5 minutes).

It has also been confirmed that when the device according to the present invention is used, the effect continues for a while (for example, about 5 minutes) after use, and that even after use of the device has stopped, flexibility is maintained to the same extent as when it was in use. Furthermore, it has also been confirmed that even if the device is not used for a long period of time (about several weeks) after use has stopped, and then used again after a long time, flexibility is maintained to the same extent as before use of the device was stopped.

As described above, the device according to the present invention induces muscle relaxation. Therefore, the device according to the present invention can be used in the field of mental care, for example, in addition to exercise and rehabilitation. One example of the use of muscle relaxation is the "progressive muscle relaxation" method developed by Edmund Jacobson. This "progressive muscle relaxation" method is known as a method of inducing physical relaxation by repeatedly tensing and relaxing muscles. The following Internet site introduces "progressive muscle relaxation" as one of the relaxation methods for mental care.

In addition, drugs are sometimes administered to relieve tension in order to improve symptoms of depression, social phobia, or insomnia. For example, paragraph 0042 of Patent No. 6739846 states that "a patient (woman in her 30s) diagnosed with depression suffers from social phobia and insomnia in addition to symptoms of depression, and has been prescribed intramuscular injections of Abilify (indication: depression) by a psychiatrist, as well as Lexotan Tablet 2 (indication: anxiety and tension due to depression) and Brotizolam Tablet (indication: insomnia)." The device according to the present invention makes it possible to relieve tension without relying on drugs, and there is no need to worry about side effects from drugs. Furthermore, even if symptoms of developmental disorders (including autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), learning disorders (learning disabilities), tic disorders, stuttering, etc.) are observed, it is possible to induce relaxation by inducing muscle relaxation and to expect relief of symptoms.

In addition, Pacinian corpuscles are sensory receptors that detect pressure and vibration. Therefore, by vibrating an instrument, it is possible to stimulate the Pacinian corpuscles with vibrations associated with music, voice, and the like. Furthermore, via the Pacinian corpuscles, it is possible to input stimuli such as musical tempo, rhythm, melody, and dynamics into the body and transmit them to the brain. As a result, the brain is able to simultaneously perceive auditory information from the ears and bodily information from the Pacinian corpuscles. Furthermore, it is possible to fuse hearing and touch, creating a situation in which a person is given a sense other than the five senses (sight, hearing, smell, taste, and touch).

In addition, the Pacinian corpuscles receive vibrations of 100 to 400 Hz, and are most sensitive to vibrations around 200 Hz. Furthermore, by using a sound source using a scale of a specific frequency, the Pacinian corpuscles can be effectively stimulated. Examples of sound sources include music that is composed only of scales (scale frequencies) from around 100 Hz to around 400 Hz, and music that uses these scales relatively frequently (for example, more than half the number of scales or time). It is also possible to compose new music or sound effects, or arrange existing music (including modulation) so that it is suitable for stimulating the Pacinian corpuscles. In addition, the term "vibration" in this invention is a term that includes various vibration modes, such as a mode having a single frequency, a mode in which multiple frequencies are synthesized, a mode in which the vibration unit changes the pressing force, a mode in which pressing is performed at uneven time intervals or displacements, a mode of less than 1 Hz, a mode in which pressing is performed while vibrating, or a mode that is a combination of these.

(Objective of this Example)
In this embodiment, a grip (the device 1 described with reference to FIGS. 1 to 5) was used and a test was conducted on the following eight men and women of different ages (hereinafter referred to as subjects) in the following manner.

(subject)
Randomly selected men and women (8 people in total) in their 20s to 70s were measured.
1 woman in her 20s, 2 men in their 30s, 1 woman, 1 man in her 40s, 2 women, 1 woman in her 70s The attributes of the subjects measured are shown in Table 1 below.

(Measurement Method 1)
The subjects were asked to perform three types of measurement exercises (side bending, leg lifting, and waist twisting) under three conditions: manual (not holding anything), bar grip (holding a bar), and grip grip (holding a grip), and were asked about muscle pain and stretching during muscle stretching. As a result, it was confirmed that for all three types of measurement exercises (side bending, leg lifting, and waist twisting), muscle pain and stretching during muscle stretching was lower for all subjects when using grip grip compared to manual and bar gripping.

(Measurement method 2)
The subject stood in a specified position, and three types of measurement movements (side bending, leg lift, and waist twisting) were recorded with video cameras (camera 1 and camera 2), and the angles of the range of motion of the joints were measured when using the bare hand (nothing being held), when holding a stick (holding a stick), and when holding a grip (holding a grip). For the measurements, a mat was placed on the floor to fix the position of the subject's feet. The video cameras were set up in front of and to the side of the subject (see Figure 9).

Specifically, the subjects were measured according to the following procedure.
The subject stands in line with a predetermined foot position reference line and performs three types of measurement exercises.
(Camera 1)
Camera 1 photographed the range of motion of the joints of the subject during various exercises, and the data was used to confirm the expansion of the range of motion of the joints.
(Camera 2)
Camera 2 photographed the subject's various exercises from the side, and confirmed from the side whether the subject's foot position was correct during exercise, and whether the subject's body was at the correct angle during each exercise.

(Type of exercise for measuring effectiveness)
The exercises used to measure the effects (hereinafter referred to as measurement exercises) were three types, namely, side bending, leg raising, and waist twisting, performed on each side (see FIG. 10).

(Foot positioning)
The subject's distance from camera 1 was kept constant, and the subject was positioned so that he or she was standing perpendicular to the line of sight of camera 1, as follows.
(a) Foot position for lateral bending and twisting (see Figure 11)
- The subject's shoe was placed so that the tip of the toe was aligned with the foot positioning line.
The foot width was determined by dividing the vertical center line (CL) into two widths that were comfortable for each subject.
- To ensure that the subject's foot could return to its original position if it shifted during the test, tape T was attached to the tip of the shoe and to the floor in a position determined by the subject, as shown in the illustration.
- We checked the footage from Camera 1 to see if the subject's standing position was correct during the movement measurement, and determined whether the data could be used.

(b) Foot position when lifting the foot (see FIG. 12)
The subject stood with the heel of the shoe of the foot to be raised and the side of the shoe aligned with line L, which is indicated as the foot position reference line.
After determining the position of the foot to be lifted, the subject's supporting foot was set so that it was attached to the shoe to be lifted, and the heel was positioned along the border indicated by line L.
-The subjects checked their foot position each time they performed the leg-raising exercise.
- We checked the footage from Camera 2 to see if the subject's foot position was correct during the movement measurement, and determined whether the data could be used.

(Measurement Procedure)
(a) The subjects were asked to gather individually at set times.
(b) The purpose of the measurement, the purpose of use of the data, safety management, and risks were fully explained to the subjects.
(c) The location of the subject's Pacinian corpuscles was detected and marked with a marker using the method described below (see Detection of the Location of Pacinian Corpuscles below).
(d) Before the test, participants were asked to do about five minutes of warm-up exercises to prepare their bodies.
(e) After the warm-up exercise was completed, the measurement exercise began immediately.

(Detecting the location of Pacinian corpuscles in the palm of the hand)
As mentioned above, the Pacinian corpuscles in the palm are one of the mechanical receptors found in the skin, and as explained in Figure 1, they are located on the tip of the middle finger and in the palm below the little finger, and are joint ranges of motion that detect pressure.

(Detection of the position of the Pacinian corpuscle of the middle finger: see FIG. 13(a))
The location is easy to detect because it is located on the tip of the middle finger, and the test was performed to help the patient recognize the throbbing sensation felt when pressing on the Pacinian corpuscle.
(a) The subject was asked to use an acupressure stick to stimulate the pad side of the middle finger in different locations and feel the difference in stimulation when pressed with the acupressure stick.
(b) Next, the center of the tip of the pad side of the middle finger (first joint) was pressed slowly and quickly with an acupressure stick to detect the location of throbbing pain.
(c) Next, the area of pain (Pacini point) was marked with a marker.

(Detection of the location of Pacinian corpuscles in the palm: see FIG. 13(b))
In the measurements of this example, Pacinian corpuscles were detected in the palm of the hand that was pressed.
(a) The palm of the hand was stimulated using a pressure point stick at different locations, and the participants were asked to feel the difference in stimulation when pressing with the pressure point stick.
(b) Next, the center of the palm on the little finger side was pressed slowly and quickly with the pressure point pressing stick to detect a spot that felt like a sharp pain similar to that felt with the middle finger.
(c) Next, the area of pain (Pacini point) was marked with a marker.
In addition, the Pacinian corpuscles were located in approximately the same position on the palm of the hand, on the tip of the middle finger, in all subjects.

Figure 14 shows images showing the locations of the Pacinian corpuscles detected on the palms of each subject. Note that the marks made with a magic marker are difficult to see in the image in Figure 14, so they have been circled.

(measurement)
(a) At the point where the angle of each movement was maximum, two remote controls were operated simultaneously to take pictures of Camera 1 and Camera 2 in rapid succession so as not to shake the cameras. Approximately 30 pictures were taken at a time.
(b) During manual, rod, and grip grasping, the experimenter made sure that the subject did not move from the designated position to prevent any deviation in the body position (especially the position of the feet). The experimenter also made sure that the grip was properly placed over the Pacinian corpuscles and ensured that the grip was held in the designated position.
(c) There was a 3-minute interval between each of the three types of exercise, and the subjects completed the exercises.
It should be noted that, after each exercise, it is confirmed that the pressing portion 20 of the device 1 is reliably contacting (pressing) the location of the Pacinian corpuscles on the palm of the subject's hand.

(Provision of the origin)
The origin of the subject's body (the origin for measuring the effect of increasing the range of motion of the joints) was defined as follows:
First, the absolute coordinates are defined as follows:
(a) The floor is zero and the upward direction is positive.
(b) The vertical axis center line CL is set to zero, with the right direction being positive and the left direction being negative.

(Grid origin)
For use in measurements, a position on the vertical axis center line (CL) at a position 150 cm from the floor surface was defined as the grid origin.

(Subject's body origin)
The following origin was defined as the starting point for measuring the effect of increasing joint range of motion.
・Origin of right leg lift ・Origin of left leg lift ・Origin of left and right side bending

Below is the idea of the origin of the body.
(a) Draw the center line of each subject's foot. Also draw a vertical line L1 through the approximate center of the body at the location that is believed to be the femoral joint (see FIG. 15(a)).
(b) The position where the line L2 passing through the center of the foot intersects with the line L1 is set as the origin of the left body when the foot is raised (see FIG. 15(b)).
(c) The position symmetrical about the vertical axis center line CL of the origin of the left leg-raised body is set as the origin of the right leg-raised body, and the point where it intersects with the vertical axis center line CL at the height of the origin of the right leg-raised body is set as the origin of the lateral bending body (see Figure 15 (c)).

Next, the procedure for obtaining the measurement results will be described.
The measurements for each movement were compared relative to the origin of the body (see Figure 16).
(a) From the measurement images taken, select the image that shows the maximum performance for each exercise.
(b) Using the illustration function, extract only the human body from the image and paste it as image data into PowerPoint (registered trademark) (hereinafter referred to as PPT).
(c) The PPT function pastes the image at the center of the PPT screen, filling the top and bottom of the screen. This ensures that all pasted images are pasted at the center of the PPT screen at the same scale. Therefore, the grid origins of all images are in the same position on the PPT screen, allowing accurate comparison.

How to compare dimensions between manual and gripping (see Figure 17)
(a) The image pasted on the PPT was projected onto a 65-inch high-definition LCD monitor, tracing paper was attached to the screen, the origin was determined, and the dimensions of each measurement point and line copied onto the tracing paper were measured using a ruler and protractor.
(b) The measurement results were converted to actual size at the following magnifications.
When a box with an actual size of 600 mm was measured on a 65-inch screen, it was 167 mm. From this, the measurement magnification of the screen was calculated as 600/167 = 3.593 times.

Results of lateral bending (data is compiled in the same manner for leg lift and waist twist) (see Figure 18)
(a) Identify the origin of the body described above (in FIG. 18, the origin of the body for lateral bending).
(b) Place a point with a pencil on the center of the elbow joint of the image copied onto the tracing paper. On the computer PPT, place a point on the right angle of a white triangle that matches that point.
(c) Draw a straight line (vertical axis center line) from the origin of the body in lateral bending to the point.
(d) The angle of trunk flexion from the vertical center line CL is the range of motion of the lateral bending joint during manual manipulation.
(e) Using the same procedure as for manual gripping, the joint movement angle from the origin when gripping is obtained (see Figure 19).

(Comparison between bare hand and grip)
(a) Using the illustration function, the image of the grip is processed to extract only the human body.
(b) Paste the extracted image above onto the image of the bare hand.
All images of the human body only attached to the PPT were extracted to the same scale and origin. Therefore, even if the image of the gripping hand is attached to the image of the bare hand, the exact origin and scale are maintained, and an accurate comparison can be made (see Figure 20). The comparison between the bare hand and the stick grip was also performed using the same procedure.

(Comparison image of measurement results)
(lateral bending)
Lateral bending is an exercise that bends the side of the body. The exercise is performed by standing on the floor with the body straight, raising the right arm straight up so that it is parallel to the vertical axis center line, and bending the side by leaning only the upper body to the left or right without moving the lower body from the waist, as shown in the image below. In this example, the vertical axis center line and the origin of lateral bending are used as axes to perform lateral bending, and the inclination angle of the trunk when using the bare hand (θ1), the inclination angle of the trunk when holding a stick (θ2), and the inclination angle of the trunk when holding a grip (θ3) are measured, and the differences between them are compared. Note that FIG. 21 shows images of the inclination angle of the trunk when using the bare hand (dotted line) and the inclination angle of the trunk when holding a grip (solid line) (θ1).

(legs raised)
The leg lift is an exercise in which the body is raised upright with both feet together, and the left or right leg is raised forward without any recoil, as shown in the image. In this embodiment, the flexion angle (θ1) between the pivot leg and the lifting leg when using a hand, the flexion angle (θ2) between the pivot leg and the lifting leg when using a stick, and the flexion angle (θ3) between the pivot leg and the lifting leg when using a grip were measured from the origin of the leg lift, and the differences were compared. Note that FIG. 22 shows images of the flexion angle (θ1) between the pivot leg and the lifting leg when using a hand (dotted line) and the flexion angle (θ3) between the pivot leg and the lifting leg when using a grip (solid line).

(Waist twist)
The waist twist is an exercise in which the subject stands with the body straight, bends forward as much as possible, does not move from the waist down, points the left hand toward the positioning tape of the right shoe, and slowly raises the right hand from the state of extending straight down toward the vertical axis center line, twisting the body with only the upper body. In this example, the twist angle (θ1) when using manual manipulation, the twist angle (θ2) when using a rod grip, and the twist angle (θ3) when using a grip grip were measured with the intersection of the perpendicular line of the vertical axis center line and the twist angle line as the center, and the differences were compared. Note that Fig. 23 shows images of the twist angle (θ1) when using manual manipulation (dotted line) and the twist angle (θ3) when using a grip grip (dotted line).

(Comparison results)
For reference, measurement images of side bending, leg lifting, and waist twisting are shown in Fig. 24 to Fig. 26. Fig. 24(a) is an image of side bending left, and Fig. 24(b) is an image of side bending right. Fig. 25(a) is an image of leg lifting left, and Fig. 25(b) is an image of leg lifting right. Fig. 26(a) is an image of waist twisting left, and Fig. 26(b) is an image of waist twisting right. Note that Fig. 24 to Fig. 26 show measurement images of the "stick" and "grip (instrument 1)", as well as measurement images of the manual hand.

(Comparison between manual and tool (grip))
FIG. 27 is a diagram showing the measurement results and the difference (Δθ1) between the angle (θ1) measured with the “manual” and the angle (θ3) measured with the “grip (instrument 1)” as described above.
As shown in Figure 27, although there are differences in the degree, the angle is larger when gripping the grip (instrument 1) than when gripping the bare hand for all subjects 1 to 8, and it is clear that the range of motion of the joint is expanded. Only subject 7's right waist twist has a negative value for θ3, but this is a slight difference that does not affect the results of this measurement, and it can be said that the effect of the grip (instrument 1) of the present invention is clear.

(Comparison between a stick and a tool (grip))
FIG. 28 is a diagram showing the measurement results and the difference (Δθ2) of the angle (θ2) when holding the "rod" and the angle (θ3) when holding the "grip (instrument 1)" measured as described above.
As shown in Figure 28, although there were differences in the degree, for all subjects 1 to 8, the angle was larger when gripping the grip (instrument 1) than when gripping the stick, indicating that the range of motion of the joints was expanded.
In addition, when gripping a stick, the range of motion of the joints is slightly wider than when using bare hands, but the difference in the effect of increasing the range of motion of the joints when gripping a grip (instrument 1) is clear.
This is thought to be because, whereas when gripping a stick, it is easier to apply force and it appears as if the range of motion of the joints is expanded due to muscle strength, when pressure is applied to the Pacinian corpuscles by gripping, muscle pain is eliminated and the range of motion of the joints is expanded, as described in the "Discussion" section below, which is a fundamentally different action and effect.
Subject 6 was the first subject in the test, and was not able to record well for right leg lift. For the other subjects, recording and measurement were possible, and the effect was also remarkable, so the lack of data for subject 6 did not affect the results of this measurement, and it can be said that the effect of the grip (instrument 1) of the present invention is clear.

(Comparing bare hands and a stick)
FIG. 29 is a diagram showing the measurement results of the angle (θ1) when "handled" and the angle (θ2) when "stick" is gripped, as described above, and the difference (Δθ4).
As shown in Figure 29, although there were some subjects in which the angle was larger when gripping the stick than when gripping bare hands, the difference was small, and the difference in the effect of increasing the range of motion of the joints compared to when gripping the grip (instrument 1) was clear.
This is thought to be because, as mentioned above, when gripping a stick, it is easy to apply force, so it appears as if the range of motion of the joints is expanded due to muscle strength, whereas when pressure is applied to the Pacinian corpuscles by gripping, muscle pain is eliminated, as described in the "Discussion" section below, so the range of motion of the joints is expanded, resulting in a fundamentally different action and effect.
Regarding the right leg lift for subject 6, he was the first subject and we were unable to photograph him, so measurements could not be taken.

(Discussion)
As described above, it was found that applying the right pressure to the exact location of the Pacinian corpuscles in the palm of the hand with a projection of the right shape relieves muscle tension throughout the body and causes muscle relaxation. It was also found that muscle relaxation increases the flexibility of the entire body, resulting in an increase in the range of motion of the joints.

Furthermore, other measurements (not shown) made by the inventors showed that the muscle relaxant effect was cross-reactive between the left and right sides. For example, when the device was held in the right hand, muscle relaxation was evident in the muscles on the left side of the body. In contrast, when the device was held in the left hand, muscle relaxation was evident in the muscles on the right side of the body.

Taking the side bending exercises shown in Figures 24(a) and (b) as an example, when the tool was held in the right hand and side bending to the left (using Figure 24(a)), the body's flexibility was increased compared to when the tool was held in the left hand and side bending to the left. Conversely, when the tool was held in the left hand and side bending to the right (using Figure 24(b)), the body's flexibility was increased compared to when the tool was held in the right hand and side bending to the right.

[Second embodiment of the device]
Next, a second embodiment of the tool will be described. Figures 31 and 32 show a tool 200 (grip) of the second embodiment. The main difference between the tool 200 of the second embodiment and the tool 1 described so far (illustrated in Figures 1 and 8) is that the tool 200 of the second embodiment is a ring model. The name "ring model" here means that the tool has a ring (finger locking portion) that locks onto the user's finger.

(Configuration of the device 200)
The configuration of the instrument 200 according to the second embodiment will be described with reference to Figures 31 and 32. Note that descriptions of structures and functions similar to those of the above-described instrument 1 will be omitted as appropriate. The instrument 200 according to the second embodiment, like the above-described instrument 1, applies pressure stimulation to the precise positions of the Pacinian corpuscles to increase the range of motion of the joints.

The device 200 includes a main body 210 that is held by the user, a pressing portion 220 that protrudes from the main body 210, and a ring portion 230 into which the user inserts the little finger and ring finger. In Figures 31 and 32, the main body 210 has a rectangular parallelepiped shape with chamfered corners.

The ring portion 230 is fixed to the main body portion 210. When the ring portion 230 and the main body portion 210 are molded separately, various general fixing methods can be used to fix the ring portion 230 to the main body portion 210. For example, the ring portion 230 can be press-fitted to the main body portion 210, fixed using a general screw (fixing screw), or fixed using an engaging claw structure.

Two rings, a pinky ring 231 for the pinky finger and a ring finger ring 232 for the ring finger, are formed side by side in the ring portion 230, but these pinky ring 231 and ring finger ring 232 will be described later. It is also possible to integrally mold (synthetic resin molding) the ring portion 230 with the main body portion 210. In this embodiment, the main body portion 210, the pressing portion 220, the ring portion 230, and the shaft portion (connecting portion) 222 described later are made by integral molding of synthetic resin.

The pressing part 220 has a shaft part 222 that functions as a connection part, and is fixed to the main body part 210 with the shaft part 222 inserted into the main body part 210. Various general fixing methods can be used to fix the pressing part 220. For example, the shaft part 222 can be pressed into the main body part 210, fixed using a general screw (fixing screw), or fixed using an engaging claw structure. It is also possible to integrally mold the pressing part 220 with the main body part 210 (molded from synthetic resin).

The shape of the main body 210 is not limited to a rectangular parallelepiped. Various shapes of the main body 210 can be adopted, taking into consideration ease of gripping, improved functionality, and the like. For example, the main body 210 may be provided with appropriate projections and recesses, taking into consideration ease of gripping, weight reduction, and the like. Furthermore, the shape of the main body 210 may be asymmetrical, character-shaped (for example, various alphabet shapes, katakana shapes, hiragana shapes, etc.), or symbol-shaped, taking into consideration design.

When the main body 210 is held by the user, the pressing portion 220 presses and stimulates the Pacinian corpuscles present in the palm of the user's hand. The pressing portion 220 includes a contact portion 221 (Pacinian ball). The contact portion 221 has a contact surface 221a that contacts the Pacinian corpuscles, and is integrated with the shaft portion 222.

The contact portion 221 is shaped so that it can pinpoint pressure on only the Pacinian corpuscles (in this embodiment, it is ball-shaped, but it is not prevented from being shaped in any other way as long as it can pinpoint pressure on only the Pacinian corpuscles) (it is preferable that it is shaped so that it does not stimulate anything other than the Pacinian corpuscles (it does not touch or is difficult to touch). This point will be described later as a modified example (Fig. 59, Fig. 60).

The shaft portion 222 connects the main body portion 210 and the abutment portion 221. The shaft portion 222 also has the function of separating the main body portion 210 and the abutment portion 221 from the palm of the user's hand when the main body portion 210 is held by the user.

In the following description, as shown in Figures 31 and 32, the direction in which the pressing portion 220 protrudes from the main body portion 210 is defined as the Z-axis direction, the direction in which the ring portion 230 protrudes from the main body portion 210 is defined as the X-axis direction, and the direction perpendicular to the X-axis direction and Z-axis direction is defined as the Y-axis direction.

As described above, the ring section 230 has two rings, the pinky ring 231 and the ring finger ring 232, formed side by side. The user inserts the pinky finger into the pinky ring 231 and the ring finger into the ring finger ring 232, and then wraps the main body section 210 around the inside of the palm with the pressing section 220 facing the palm (FIG. 33).

The relative positions of the various parts of the device 200 are designed so that when the user grips the device 200, the abutment part 221 at the tip of the pressing part 220 comes into contact with the location of the Pacinian corpuscles. The device 200 uses the gripping force of the little finger in the little finger ring 231 and the supplementary gripping force of the ring finger in the ring finger ring 232 to press and stimulate the Pacinian corpuscles with the abutment surface 221a of the abutment part 221.

The contact portion 221 has a spherical shape that allows pinpoint pressure on only the Pacinian corpuscles (preferably a shape that does not stimulate (cannot touch or is difficult to touch) anything other than the Pacinian corpuscles). In other words, when the device 200 is used, it is preferable that a space is formed around the contact portion 221, as with the device 1 of the first embodiment. In other words, it is preferable that a region where the device 200 is not in contact with the palm (non-contact region) is formed outside the region where the contact portion 221 is in contact with the palm (contact region) so as to surround the contact region.

Such a ring model instrument (instrument 200 in this case) can also be described as follows: The most difficult aspect (or one of the most difficult aspects) of an instrument capable of compressing the Pacinian corpuscles is to prevent the sphere (Pacinian ball) from shifting from its correct position in the palm of the hand due to rotation, slippage, etc.

In other words, when developing this type of instrument, it is extremely important to place the sphere accurately at the Pacinian point (the position where the Pacinian corpuscles can be pressed accurately, also known as the Pacinian position) in the palm of the hand holding the instrument, and then to ensure that the position of the Pacinian ball does not shift from its exact position due to the pressure applied or the movement of the fingers.

In the first embodiment of the device 1 illustrated in Figures 1 and 8, as shown in Figures 3 to 7, the second stopper 11B and third stopper 11C are used to fix the grip position at three points: the thumb, index finger, and the Pacinian ball on the palm, and the palm is pressed by the force of the little finger and ring finger.

In contrast, in the device 200 according to the second embodiment, the main body 210 (grip) is positioned in the palm of the hand by three points: the little finger ring 231 attached to the main body 210, the little finger pressing portion (the portion of the main body 210 pressed by the little finger), and the contact portion 221 (Pacinian ball) of the pressing portion 220, so that the contact portion 221 is accurately fixed at the position of the Pacinian corpuscles.

Figure 33 shows the ring model of the device 200 being held in the left hand. However, the device 200 shown in Figure 33 is a schematic illustration of a prototype of the device 200 shown in Figures 31 and 32, to make it easier to show the positional relationship. Therefore, although the shape does not match that of the device 200 shown in Figures 31 and 32, it has parts that correspond to the main body portion 210 and the ring portion 230. In Figure 33, these parts are denoted by the reference numerals 210 and 230.

The location of the Pacinian corpuscles on the palm (point P, which is the Pacinian point) is located almost directly below the first joint of the little finger (the fingertip in FIG. 33) when the little finger is naturally bent in a bow shape as shown in FIG. 33. In this embodiment, the following functions are realized by providing a ring portion (little finger ring 231) on the main body portion 210 at a position opposite the base of the little finger (third joint).

In other words, in the device 200, the position of the little finger is restricted by the little finger ring 231. Therefore, when the little finger is naturally bent, the distance (distance L in the X-axis direction) between the position of the third joint of the little finger (position A on the little finger ring 231 in FIG. 33, indicated by a circle) and the imaginary tip of the pressing part 220 (point C indicated by a triangle, or Pacinian point P indicated by an oval) is kept constant. Therefore, the pressing part 220 of the main body 210 accurately hits the Pacinian point (point P).

In addition, the angle θ (θ°) between the ring portion 230 and the main body portion 210 is fixed, and the area pressed by the little finger (point B, indicated by a triangular mark) and the pressing portion 220 are aligned on the arc (D) formed by the little finger and the palm of the hand, so that the pressing force of the little finger accurately acts as pressure on the Pacinian corpuscles. Furthermore, point B is aligned almost exactly on the same line as the above-mentioned points C and P.

The pressure force (pressure, indicated by arrow F) on the Pacinian corpuscles is generated by the little finger and ring finger (mainly the little finger). When the main body part 210, whose position is restricted by the ring part 230, is pressed mainly by the force of the little finger, the axial force causes the pressing part 220 (tip at point C) to sink into the palm. In addition, the force of the little finger etc. pressing almost directly from above generates a frictional force between the main body part 210 and the palm. Then, the force from almost directly above combined with the restriction by the ring part 230 suppresses left and right rotation of the instrument 200 (left and right rotation, which is a displacement around the Z axis) as shown in Figure 33.

Therefore, when the user grasps the main body 210, the instrument 200 is affected by the pressure of the little finger and ring finger and does not move in any direction, but is stably fixed in an accurate position. Then, the pressure force F acts directly on the Pacinian corpuscles. Furthermore, the instrument 200 is supported at three points, the little finger ring 231 (point A), the part pressed by the little finger (point B), and the pressing part 220 (point C), so that the angle θ between the little finger and the palm is maintained and the instrument 200 is stably fixed in an accurate position. Then, compared to the instrument 1 of the first embodiment, it becomes easier to perform accurate pressure on the Pacinian corpuscles.

To fix the main body 210, the first joint on the tip side of the little finger needs to be in contact with the main body 210 at point B. It is desirable to determine the shape and dimensions (size) of the main body 210 and its relationship with the little finger so that a gap (gap 882 in FIG. 52) can be secured between the little finger and the main body 210 at points other than point B. By floating the little finger (the portion from point B to the base) above the main body 210, space can be secured for moving the little finger, and the force applied from the little finger to the main body 210 can be easily adjusted.

(Effects of using the device 200)
According to the ring model device 200 as described above, the range of motion of the joint can be expanded to the same extent as the device 1 of the first embodiment (illustrated in FIG. 1 and FIG. 8). FIG. 57 shows the results of an experiment on the effect of expanding the range of motion of the joint by the device 200. For comparison, a type without a ring portion (called the "Nike model") was used, as shown in a different orientation in FIG. 68(a) and (b). This type has the basic functions of the device 1 of the first embodiment shown in FIG. 1 and FIG. 8, and has a main body portion 10 and a pressing portion 20 like the device 1.

As a result of an experiment on the effect of expanding the range of motion of a joint using the Nike model shown in Figure 68 and the ring model (instrument 200) shown in Figure 31, it was confirmed that the range of motion of the joint can be expanded to the same extent with both models as long as there is no difference in the pressing force of the pressing parts (20, 220) (see Figure 57). From top to bottom, Figure 57 shows photographs of lateral bending in the case of bare hands (not holding anything), when using the Nike model, and when using the ring model.

As shown in Figure 57, when using bare hands (top image), the subject's right arm stops at a position higher than horizontal. In contrast, when using the Nike model (middle image) and the Ring model (bottom image), the subject's right arm reaches a position lower than horizontal to the same extent.

As mentioned above, with regard to misalignment in the rotational direction, the provision of the ring portion 230 makes it possible to prevent rotation around the Z axis (left and right rotation), making it easier to accurately press the Pacinian corpuscles than with the instrument 1 of the first embodiment.

[Application]
As long as no hindrance occurs, the tool 200 can be used for various purposes such as for improving athletic function, for track and field, for ice sports, for rehabilitation, etc., in the same manner as the tool 1 of the first embodiment (illustrated in Figs. 1 and 8, etc.) Furthermore, the uses of the ring model tool 200 can be explained as follows.

For example, when performing serious exercise like an athlete or professional sports player, it is considered more appropriate for the angle between the thumb and index finger to be restricted. Also, for example, if the hand is opened for some reason while holding the device 1 of the first embodiment while exercising, the device 1 may fall and become easily damaged. However, in the ring model device 200, the fingers are passed through and engaged with the ring portion 230, so the device 200 will not fall even if the palm of the hand is opened. In other words, the ring model will not easily fall off the palm of the hand even if the hand is opened, because of the little finger ring (little finger ring 231).

In addition, the three fingers, the thumb, index finger, and middle finger, are not restricted by the ring portion 230 and can be moved freely while using the device 200. Therefore, the impact on movement is kept to a minimum.

Furthermore, the ring model device 200 can be held by the little finger, ring finger, and palm, and there is no need to extend the main body 210 to the thumb or index finger, so it is small and easy to carry. Because it is easy to carry, for example, when an average person is doing daily exercises, walking, jogging, hiking, etc., the effect of the device 200 (grip effect) causes muscle relaxation throughout the entire body, making it easier to get a sense of an expanded range of motion in the joints on a daily basis. And compared to performing these actions without gripping the device 200, effects such as lifting the legs can be obtained more comfortably, and the feeling of the whole body being lighter can be felt more regularly.

Generally, there are individual differences in the size and shape of the palm, the shape and length of the fingers, and the location of the Pacinian point. Furthermore, as children grow, the size of their hands and the Pacinian point change almost every year. For this reason, the most effective results can be achieved by creating a device (personal grip) with a shape and size that fits the individual's palm, depending on individual differences or on the age or generation.

[Invention of a method for identifying Pacini points]
Next, the embodiments of the method for identifying Pacinian points according to the present invention will be described. Note that the same reference numerals are used to designate the same parts as those in the device 1 according to the first embodiment and the device 200 according to the second embodiment, and the description thereof will be omitted as appropriate.

(First embodiment of the invention of a method for identifying Pacinian points)
As mentioned above, the location of the Pacinian point varies from person to person. Therefore, by creating a tool (personal grip) with a shape and size that fits the palm of the person according to individual differences or according to age or generation, the effects of the tool 1 or tool 200 can be easily achieved.

Furthermore, the Pacinian corpuscles in the palm of the hand are sensory receptors with a size of about 1 mm, which are present only in one place on the palm. It has been found that the range of movement is maximized by accurately pressing the location of the Pacinian corpuscles (Pacinian point). For this reason, the first embodiment of the invention described here (the invention of the method for identifying the Pacinian point) aims to accurately detect the Pacinian point. The following literature explains that the Pacinian corpuscles are about 0.5 to 2 mm in size and have a diameter of about 0.7 mm.
Tadashi Oyama et al., "New Edition: Handbook of Sensory and Perceptual Psychology", 1994/1/20, P.1180-p.1181

[Comparison test of range of motion depending on the location of pressure on the Pacinian corpuscles]
First, the inventors detected the exact Pacinian points (Pacinian positions) of a specific subject by using the subject's own senses. The detection of the exact Pacinian points was performed in the same manner as the detection of the positions of the Pacinian corpuscles (Pacinian points) on the palm of the hand ( FIG. 13( b )) in the first embodiment of the device 1.

Figure 34 (a) shows an image of the subject's palm taken at that time. A mark was made on the palm with a marker (felt-tip pen; the "marker" mentioned so far also refers to a felt-tip pen). The position of the mark at this time is called point P.

Next, points a certain distance (3 mm in this case) up, down, left and right from point P were determined in clockwise directions at 90 degree angles, designated as points A, B, C and D. Then, an instrument (instrument 1 in this case) was grasped and pressed with approximately the same force at each point, including point P, while performing lateral bending movements to measure the expansion of the range of motion of the joint.

[result]
Even when points 3 mm away from point P (points A to D) were pressed, the range of motion of the joint was clearly narrower than when point P was pressed. In Figure 34(b), the five images labeled "P" and "A" to "D" at the top of the figure (the end on the subject's head side) show the state of lateral bending when point P and points A to D are pressed.

A horizontal line is added to these images, based on the position of the subject's elbow joint in the image marked with the letter "P" (the image at the left end of Figure 34 (b)). When the image at point P on the left end is compared with the images at points A through D marked with the letters "A" through "D," it is clear that when point P is pressed, the subject's elbow joint reaches below the horizontal line.

It can be seen that when point P is pressed, the subject's elbow joint reaches a lower position than when points A through D are pressed. In addition, when points A through D are pressed, only the same degree of flexibility is exerted in all cases. Therefore, it is effective to accurately find (identify) and press the Pacinian point (point P). In addition, to accurately press the Pacinian point, it is necessary for the user to be able to recognize the identified Pacinian point immediately before using the device.

[Pacini Point Identification System]
In consideration of the above-mentioned results and circumstances, in the first embodiment of the invention of the method for identifying the Pacinian points, the Pacinian points on the palm of the hand are accurately detected, and the detected Pacinian points can be reproduced by the user before using the tool. The system of this embodiment (Pacinian point identification system) will be described below.

The system of this embodiment (Pacinian point identification system, hereinafter sometimes simply referred to as the "identification system") stimulates the Pacinian corpuscles and measures the human body reaction that occurs at that time. As the human body reaction, various reactions that appear in the human body in response to stimulation of the Pacinian corpuscles can be used. Examples of the human body reaction include action potentials, brain activity, hormone secretion, and blood flow. In the identification system of this embodiment, action potentials are used as the human body reaction.

The fact that stimulating the Pacinian corpuscles generates an action potential has been explained and proven in various media. The following are examples of literature that describes action potentials and their measurement:

Hiroyuki Izumi (2011), "Humans from a Physiological Perspective", Journal of Dental Medicine, Medical University of Hokkaido
https://core.ac.uk/download/pdf/268116367.pdf

The right-hand column of page 11 of this paper (lines 7 to 11) states, "The Pacinian corpuscles of the touch receptors generate an activation potential at their endings depending on the intensity of pressure or vibration stimuli. As the stimulation increases, the activation potential increases, generating an action potential in the sensory nerve, which is transmitted to the central nervous system and recognized as a sensation."

Other examples include the following:

Action potentials can be measured using an action potential measuring device (also called an "action potential measuring device," "action potential measuring means," "human body response measuring device," "human body response measuring device," or "human body response measuring means"). Previous research by the inventors (for example, various research such as the research in the experiment described using Figure 14) has revealed that the Pacinian point on the palm of the hand is located within a roughly 2 cm square area for all people. This 2 cm square area will be referred to as the "distribution area" below. Figure 35 shows that point P of a certain subject is located almost in the center of the distribution area, which is shown enclosed in a square frame.

In the Pacinian point identification system of this embodiment, a rod-shaped object with a thin tip (with a tip diameter of about a few mm) is pressed within such a distribution area, and the action potential is measured by an action potential measuring device.

Figures 36 and 37 show a schematic configuration of a Pacinian point identification system (identification system) 600 according to this embodiment. In this identification system 600, a point identification device 601 is used. In the point identification device 601, a linear guide 604 is provided on a base plate 602 having a flat surface. The linear guide 604 includes an X-axis stage 606 and a Y-axis stage 608, and the X-axis stage 606 and the Y-axis stage 608 are capable of linear displacement in directions perpendicular to each other.

As shown in FIG. 37, the Y-axis stage 608 is provided with a Z-axis displacement mechanism 610, which holds a pressure rod (pressing body) 612. The pressure rod 612 can be displaced in the Z-axis direction via an elastic body (e.g., a coil spring or a leaf spring) 613. Here, the Z-axis direction is perpendicular to the plane formed by the X-axis and Y-axis (similar to the flat surface of the base plate 602). Here, the X-axis, Y-axis, and Z-axis of the identification system of this embodiment are defined for the point identification device 601.

As shown in FIG. 36, the subject's arm (here, the right arm) 314 can be placed on the base plate 602. The base plate 602 is provided with a stopper 616 that protrudes upward to engage the subject's arm 614.

Two electrode sheets 618 are attached to the subject's arm 614, and the electrode sheets 618 are connected to an action potential measuring device 620. As the electrode sheets 618 and the action potential measuring device 620, various general devices can be used as long as they are capable of measuring the action potential. For example, as the action potential measuring device 620, a general oscilloscope or a PC (personal computer) capable of displaying input waveforms can be used. It is also possible to use electrodes with needles (needle electrodes) instead of the electrode sheets 618.

The X-axis stage 606, Y-axis stage 608, and Z-axis displacement mechanism 610 may be automatically controlled via a controller (not shown), or may be manually displaced by a measurer (operator). Alternatively, a combination of automatic and manual mechanisms may be used, for example, with the X-axis stage 606 and Y-axis stage 608 being automatically controlled and the Z-axis displacement mechanism 610 having a manually displaced pressure rod 612.

To identify the Pacinian point, the subject first places his/her arm 614 on the base plate 602 with the palm facing up. The subject places the part of the arm 614 on the pinky finger side against the stopper 616 and positions the palm below the linear guide 604.

The measurer moves the linear guide 604 to move the pressure rod 612 in the XY plane, guiding it to the aforementioned distribution area (a 2 cm square area in Figure 35) on the palm below the little finger. The measurer moves the pressure rod 612 arbitrarily in the XY plane so as not to go too far outside the distribution area. The measurer then stops the pressure rod 612 at a position of their choice, and lowers it once it has stopped.

When the lowered pressure rod 612 hits the palm and presses against it, an electrical signal representing the action potential at that time is detected by the electrode sheet 618 and input to the action potential measuring device 620 via the electrode sheet 618. Based on the input electrical signal, the action potential measuring device 620 displays a waveform corresponding to the change in the action potential on the screen. The person measuring the action potential then moves the pressure rod 612 to the surrounding area, observing the waveform at each destination.

The location where the waveform is most clearly visible is determined to be the Pacinian point, and a mark is placed at that location. This mark may be a sticker affixed by the person taking the measurement, or it may be ink drawn with a pen tip attached to the tip (here, the bottom end) of the pressure rod 612.

According to the invention (first embodiment) of the method for identifying Pacinian points as described above, it is possible to search for and identify Pacinian points at intervals (pitch) according to the performance (resolution) of the linear guide 604 in the point identification device 1. For example, if the performance of the linear guide 604 is such that the pressing rod 612 can be moved every 0.1 mm, the Pacinian points can be identified in units of 0.1 mm. Then, by using the instrument 200 with the identified position as a marker, it becomes possible to use the instrument (instrument 1, instrument 200, etc.) appropriately.

In this embodiment, the identification system 600 is equipped with a linear guide 604 to identify the Pacinian points, but this is not limited to this, and for example, the linear guide 604 may be omitted. In this case, the measurer can identify the Pacinian points by pressing the pressure rod 612 held in his/her hand against the palm one after another within the distribution area (Figure 38) and checking the change in the action potential with the action potential measuring device 620 (referring to Figure 36).

In addition, the identification system 600 makes it possible to identify Pacinian points based on changes in the action potential measuring device 620, so it is possible to find Pacinian points more objectively than when the identification system 600 is not used. And it is possible to find Pacinian points scientifically without relying on the skill of the measurer or the subject's senses.

This makes it possible to set up dealers, sales agents, exhibition halls, showrooms, antenna shops, and handling stations (hereinafter referred to as "dealers, etc.") for devices (such as device 1 and device 200) in a wide area both domestically and overseas, and to introduce the specific system 600 to each dealer. Furthermore, it becomes possible to realize a business model in which a specific person (such as the manager of each store) at each dealer clearly identifies the pachinni points of each customer and then sells the device (such as device 1 and device 200). This makes it possible to make the most effective use of the devices (such as device 1 and device 200).

In addition, as described above, the identification system 600 can find Pacini points objectively. Therefore, there is no need to provide time-consuming, advanced education or training to employees of stores, etc., to enable them to find Pacini points.

Furthermore, it is conceivable that the specific system 600 may be installed and used at the home of a user of the device (such as device 1 or device 200). In this case, for example, it would be possible for the user to identify the Pacinian point every morning before using the device (such as device 1 or device 200), so that the Pacinian point can always be stimulated accurately.

(Creating a support jig)
It is also possible to create an auxiliary tool (also called a "support tool,""2D support tool,""2Dtool," or "template") that identifies and records the Pacinian points for each user, and use this auxiliary tool as a positioning format (positioning format) to always easily reproduce the Pacinian points. The auxiliary tool (support tool) was considered for the following reasons.

In other words, if the identification system 600 as described above is installed in a store or the like, the exact location of the Pacinian points can be found by using the identification system 600 at the store or the like. However, a user of an appliance (such as appliance 1 or appliance 200) needs to know his or her own Pacinian points immediately before using the appliance every time. Also, if a user installs the identification system 600 at home as described above, problems with costs and installation space are likely to arise. Therefore, technology is needed that allows users to easily identify Pacinian points.

At a store or the like, the identification system 600 is used to find the exact Pacinian point, and the Pacinian point is marked on the spot with a marker or the like, and a photograph of the palm of the hand is taken with a camera. The camera used here may be a dedicated camera such as a digital camera, or a camera installed in a smartphone, mobile phone, tablet terminal, notebook PC, e-book reader, wearable computer, or portable game console. The camera may also be a camera owned by the user. Furthermore, the photograph may be taken by the user using his or her own camera, or may be taken using a camera owned by the store or the like.

Next, based on the image data of the photographed palm, the photographed image of the palm is printed at the same magnification (actual size) on, for example, a transparent acrylic plate (transparent plate as a transfer substrate). Figure 39(a) shows a schematic of a transparent plate 622 on which an image of the palm has been printed. Note that the printing form of the palm image can be semi-transparent. In addition, any of a variety of general printers can be used for this purpose, as long as they are capable of printing on transparent plates.

After this, a hole 624, for example of a perfect circle, is made at the Pacinian point of the palm drawn on the transparent plate 622. The diameter of this hole 624 is set to a size that allows the tip of a writing implement 626, such as a general ballpoint pen or marker, to pass through, as shown in Figure 39(b) described below.

Before grasping an instrument (such as instrument 1 or instrument 200), the user places the corresponding palm of the hand against transparent plate 622 so that it matches the image of the palm. FIG. 39(b) shows a schematic of the state in which the palm is placed against transparent plate 622. The user inserts the tip of writing implement 626 into hole 624 from the side of the plate opposite the side where the palm is placed, and makes a mark on the palm.

In the example of Figures 39(a) and (b), a guide tube 628 is provided on the transparent plate 622 to guide the writing implement 626 and prevent the writing implement 626 from tilting. The transparent plate 622 also has a standing wall 630 that forms a space for placing the palm and allows the palm to be inserted. Furthermore, the reference numeral 632 in Figure 39(b) denotes a printed layer with an image of a palm.

In this way, by creating the transparent plate 622 as an auxiliary tool (support jig) and using the transparent plate 622 to mark the palm of the hand, the exact location of the Pacinian points can be indicated on the palm of the hand. Then, by placing the contact portion (such as 21 or 221) of an instrument (such as instrument 1 or instrument 200) on the marked Pacinian points, the Pacinian corpuscles can be accurately pressed.

That is, the Pacinian points that have been accurately measured by the specific system 600 are marked, a photograph of the palm is taken, and a transparent plate 622 is created with a copy of the palm image that is the same size as the user's hand. Furthermore, a hole 624 is made in the part of the transparent plate 622 that corresponds to the Pacinian point (Pacinian point part), and this transparent plate 622 is given to the user.

The user can reproduce the exact Pacinian point each time by placing the palm of the hand against the transparent plate 622, inserting a ballpoint pen through the hole 624, and making a mark on the palm. The user can then use an instrument (such as instrument 1 or instrument 200) on the exact Pacinian point without the burden of searching for the Pacinian point each time.

The user of the equipment needs to know the exact location of the Pacinian points when starting exercise with the equipment (grip exercise). In other words, it is most effective to press the Pacinian points accurately when exercising or walking with the equipment.

To achieve this, the user must mark his/her own Pacinian point immediately before starting exercise, etc., and must grasp the device while being aware that the pressure part (pressure part 20, 220, etc.) must be placed precisely on the Pacinian point. It is also desirable for the user to mark the exact position of the Pacinian point on their hand each time before exercising at home, in the office, at the gym, etc. Then, by using an auxiliary tool (support jig), the position of the Pacinian point can be easily clarified. As a result, it becomes easier to promote proper use of the device. It can also promote daily use of the device, such as every day, in the morning and evening, etc.

(Second embodiment of the invention of the method for identifying Pacinian points)
[background]
Next, a second embodiment of the invention of a method for identifying Pacinian points will be described. In the method of this embodiment, data (sample data) of a large number of collected Pacinian points is processed using AI (artificial intelligence) (FIGS. 45 and 46), and the optimal Pacinian points are selected to create an auxiliary tool (support jig) (FIG. 46).

Figures 45 and 46 show a schematic diagram of the configuration of the identification system 700 according to this embodiment and the identification method executed by the identification system 700. Of these, Figure 46 is given the name "Pacini point detection and printing system," and this name refers to the identification system 700 according to this embodiment.

In the identification system 700 (and identification method) shown in Figures 45 and 46, first, a predetermined number of men and women (for example, about 100 men and women, totaling about 200 men and women) are selected as sample collection subjects. Then, as shown in the bottom row of Figure 45, the Pacinian points of each sample collection subject are identified, and the identified Pacinian points (points P) are marked with a writing implement or the like (step (S) 710). These samples will later become samples (AI samples) that will be processed by AI.

Here, Fig. 45 and Fig. 46 show each step of the identification method using a partial configuration of the identification system 700. S710 in Fig. 45 means a step of the identification method executed in the identification system 700. Other symbols with "S" such as "S720" and "S730" also mean each step of the identification method.

Various methods can be used to identify the Pacinian points in S710 of FIG. 45. For example, various methods can be used, such as the sensory recognition method shown in FIG. 13(a) and (b) and the action potential method shown in FIG. 36 to FIG. 38. FIG. 40 illustrates a method in which the measurer stimulates the left hand of the sample collection subject using a pressure rod (round rod, pressure body, acupressure rod, etc.) as in FIG. 13(b). Having a skilled worker identify the Pacinian points at this time will result in more accurate identification.

Next, the hand of each individual with the Pacinian points marked is photographed (S720). FIG. 41 shows only a partial sample (six people) as an example. To photograph each individual's hand, it is possible to use a point photographing device 702 as shown in FIGS. 42(a) and (b). In the point photographing device 702 in FIG. 42, a hand side stopper 706 and a little finger stopper 708 are provided on a base plate 704 so as to protrude upward.

Furthermore, a camera 710 is attached to the point photographing device 702. A camera smaller than the palm of a hand is used as the camera 710. When photographing the Pacini point with the camera 710, the hand of the individual to be photographed (the left hand in FIG. 42(a)) is placed on the base plate 704, and the palm of the hand is directed toward the camera 710, which is positioned above the base plate 704.

When the hand is placed on the base plate 704, the position of the hand is fixed by placing the side of the hand against the hand side stopper 706 and the little finger against the little finger stopper 708. The shooting range of the camera 710 is adjusted to include the entire palm. The entire palm is then photographed by the camera 710, and image data of the palm, including the Pacinian point, is obtained.

The palms of all sample collection subjects are photographed in this way (S730). Then, attribute data of the sample collection subjects (e.g., data such as gender and age) and data obtained from the palm images are compiled into a database and used as big data for Pacinian point detection using AI.

Before searching for Pacinian points, AI learning (AI learning) is performed in advance (S740). For AI learning, for example, data on the hand feature points of each individual linked to the attribute data of the sample collection subjects is collected (learning feature point data). Examples of learning feature point data include data on the size and shape of the palm, the shape and length of the fingers, and the length and position of each finger joint.

Data items that indicate the size of the palm include the length from the wrist to the tip of each finger, the length of each joint of each finger, the thickness (width) of each joint, and the area of the palm (the area including the fingers or the area excluding the fingers). Furthermore, examples of measuring these items include recognizing the wrinkles and joints of the wrist using image processing, setting a part of this (such as the center) as a reference point, and measuring the distance from the reference point to the fingertips and joints.

AI learning is performed by a processing device (not shown). The processing device may be a computer equipped with a central processing unit (CPU) and various storage devices. The processing device may also be a computer in which multiple computers are connected via a communication network. Furthermore, the processing device may be a computer connected to a computer (such as a server device) installed at a location where the Pacinian points are identified and a computer in a remote location.

In AI learning, classification is performed for each combination of attribute data (for example, a combination of gender and age), and a combination of multiple learning feature point data corresponding to each classification and position data of the Pacinian points is used as training data. For example, the attribute data and multiple learning feature point data corresponding to each classification are used as explanatory variables, and the position data of the Pacinian points is used as the explained variable (objective variable).

There are various possible applications for the training feature data. For example, the correlation between items such as the length from the wrist to the tip of each finger, the length of each joint in each finger, etc., can be quantitatively analyzed, and a function for regression analysis can be created from the relationship between the analysis results and the position data of the corresponding Pacinian points.

The AI learning method is not limited to the above-mentioned machine learning with supervised learning, but can also be other machine learning methods such as unsupervised learning and reinforcement learning. The analysis method in machine learning is not limited to regression analysis, but can also be decision trees. In addition, when the position of the Pacinian point is output as, for example, multiple candidates or within a region of a predetermined size, rather than as coordinates that specify a single position, clustering or other analysis methods can also be used as the analysis method. Furthermore, the AI learning method is not limited to statistical machine learning, but can also be deep learning.

When performing this type of AI learning, learning feature point data and position data of the Pacinian points are acquired. To acquire the position data of the Pacinian points, certain coordinates (such as two-dimensional Cartesian coordinates or polar coordinates) are defined. To determine the origin of the coordinates, it is possible to use the origin determined by the hand side stopper 706 and the little finger stopper 708. It is also possible to set the origin on the image of the palm and use a specific position on the palm (for example, the tip of the middle finger or the center of the wrist width) as the origin.

When using the results of AI learning to search for Pacinian points, as shown in the lower left of Figure 46, the palm of the user (the subject in this case) who wishes to identify the Pacinian points is photographed (S712, S722). A palm photographing device is used to photograph the palm. For example, a palm photographing device with the same configuration as the point photographing device 702 described above can be used (S722). The point photographing device 702 described above can also be used as the palm photographing device as is. Here, an example will be described in which the point photographing device 702 is used as a palm photographing device.

When photographing the palm of the hand, the position of the hand is fixed by placing the palm against the hand side stopper 706 and the little finger stopper 708. The photographing range of the camera 710 is adjusted so that the entire palm is included. The entire palm is then photographed by the camera 710, and image data of the palm is obtained.

From the acquired palm image data, data on the characteristics of the user's hand (user feature data) is extracted (S732). As with the AI learning described above, examples of user feature data include data such as the size and shape of the palm, and the shape and length of the fingers. Examples of data items that indicate the size of the palm include the length from the wrist to the tip of each finger, the length of each joint of each finger, the thickness (width) of each joint, and the area of the palm (the area including the fingers, or the area excluding the fingers). Furthermore, measurements of these items can be performed, for example, in the same manner as with the AI learning described above.

Next, using the user's attribute data (e.g., data such as gender and age) and user feature data, a calculation is performed based on the results of AI learning to calculate the location of the Pacinian points (S742). The locations of the user's Pacinian points are then identified (discovered) by estimation, and data on the identified Pacinian point locations (Pacinian point location data) is saved (S750).

After this, a mark is placed on the user's palm based on the Pacinian point position data identified by the AI, and the palm is photographed (S760). To place the mark on the palm, for example, a point printing device 711 with a photographing function, as exemplified in Figures 43(a) and (b), can be used.

In the point printing device 711 of Figures 43(a) and (b), a linear guide 714 is provided on a base plate 712 having a flat surface, similar to the point identification device 601 (Figures 36 and 37) in the identification system 600 described above. The linear guide 714 is equipped with an X-axis stage 716 and a Y-axis stage 718, and the X-axis stage 716 and the Y-axis stage 718 are capable of linear displacement in directions perpendicular to each other.

As shown in FIG. 43(b), the Y-axis stage 718 is provided with a Z-axis displacement mechanism 720, which holds a print rod 722. A common writing implement such as a ballpoint pen or a felt pen can be used as the print rod 722. The print rod 722 can be displaced in the Z-axis direction via an elastic body (such as a coil spring or a leaf spring) 723.

Here, the Z-axis direction is a direction perpendicular to the plane formed by the X-axis and Y-axis (similar to the flat surface of the base plate 712). Furthermore, the X-axis, Y-axis, and Z-axis in this embodiment are set in the same directions as the respective axes in the specific system 600 of the embodiment described above.

As shown in FIG. 43(b), the Y-axis stage 718 is provided with a camera 724 capable of photographing the area below. The camera 724 may be the same as the camera 710 of the point photographing device 702 shown in FIGS. 42(a) and (b).

The X-axis stage 716, Y-axis stage 718, and Z-axis displacement mechanism 720 may be automatically controlled via a controller (not shown), or may be manually displaced by the measurer (operator). Alternatively, a combination of automatic and manual mechanisms may be used, for example, with the X-axis stage 716 and Y-axis stage 718 being automatically controlled and the Z-axis displacement mechanism 610 being manually displaced by the print bar 722.

As shown in FIG. 43(a), the arm (here, the right arm) 426 of the person to be marked can be placed on the base plate 712. The base plate 712 is provided with a hand side stopper 728 and a little finger stopper 730 that protrude upward. The arm 726 of the person to be marked is then positioned with the side of the hand on the little finger side against the hand side stopper 728 and the tip of the little finger against the little finger stopper 730.

The X-axis stage 716 and Y-axis stage 718 move the printing stick 722 so that the tip of the printing stick 722 is directly above the Pacinian point (point P) based on the Pacinian point position data identified by the AI. Then, as shown in Figure 43 (b), the printing stick 722 is lowered in the Z-axis direction, the tip of the pen is placed against the palm of the hand, and the Pacinian point (point P) is marked.

After this, for example, the palm is photographed by camera 724, and image data of the palm is acquired. Furthermore, based on the image data of the palm, the photographed image (two-dimensional image) of the palm is printed at the same magnification (original size) on, for example, a transparent acrylic plate (transparent plate as a transfer substrate), in the same manner as shown in Figures 39(a) and (b) relating to the "First embodiment of the invention of a method for identifying Pacinian points." Then, in the same manner as shown in Figures 39(a) and (b), an auxiliary tool (support jig) is created, and the palm is marked via the auxiliary tool, thereby indicating the exact location of the Pacinian points on the palm.

Alternatively, instead of the flat printed assisting tool described above, a three-dimensional assisting tool (also called a "3D support tool," "3D tool," or "template") may be created. Figure 44 shows, from left to right, the steps for creating and using a three-dimensional assisting tool. Also, the lower left part of Figure 46 shows a method for identifying Pacinian points when using a three-dimensional assisting tool.

The left edge of Fig. 44 shows a hand that has been marked using AI. This mark has been made by the point printing device 711 in Fig. 43. A 3D scan is performed on this hand using a 3D scanner (reference number 740 in Fig. 46), and 3D scan data such as that shown in the next row (adjacent to the right) of Fig. 44 is obtained (S770).

The 3D scan data also includes data on the Pacinian points. Here, the "Pacinian points" written in Figure 44 refer to the Pacinian points. After this, as shown in the next part of Figure 44, the 3D scan data is used in conjunction with 3D CAD (reference number 742 in Figure 46) to create female mold data for making a palm mold 748 (S780).

When 3D scan data is imported into 3D CAD, it is possible to import the 3D scan data from the communication interface of the 3D scanner into the PC (personal computer) via the communication interface of the PC. Furthermore, in the PC, the 3D scan data is loaded into a spreadsheet software, and the numerical data is loaded into the 3D CAD from the numerical data sheet created in the spreadsheet software. In this way, after the 3D scan data is imported into the 3D CAD, the 3D CAD performs data correction (such as multiplication of a predetermined coefficient) as necessary. In the spreadsheet software, it is possible to list the coefficients of each part (various coefficients used to calculate variables), and import the coefficients of each part from the spreadsheet software into the 3D CAD. It is also possible to perform calculations using the coefficients in the spreadsheet software, and import the calculation results into the 3D CAD. The design values of the female mold data determined in the 3D CAD (or imported into the 3D CAD) are sent from the communication interface of the PC to the communication interface of the 3D printer (reference number 744 in FIG. 46) and are loaded into the 3D printer (reference number 744 in FIG. 46). In the following, we will omit explanations of sending and receiving such data as appropriate.

Next, in cooperation with a 3D printer (744 in FIG. 46), a palm mold (also called a "female mold" or "3D jig") 748 is created (also called "printed" or "molded") (S790). The data format handled by the 3D printer 744 is triangular meshed polygon data. The palm mold (3D jig) 748 has a recess 750 in which the shape of the palm side of the user's hand is three-dimensionally reproduced.

When creating the palm mold (3D jig) 748, the Pacinian point is also reflected. A hole 754 into which a writing implement 752 such as a ballpoint pen can be inserted is made at the position of this Pacinian point, and an auxiliary implement 756 is created. The user's hand is then placed over the recess 750 of the auxiliary implement 756 so that it fits snugly, and the writing implement 752 is inserted into the hole 754, and a mark is made on the user's palm (S800).

According to this invention (second embodiment) of the method for identifying the Pacinian points, the Pacinian points can be identified accurately, as in the first embodiment. In addition, since the Pacinian points are identified using AI, there is no need to manually locate the Pacinian points each time, and the task of identifying the Pacinian points can be automated. Furthermore, since the auxiliary tool 756 is used, the user can easily identify the position of the Pacinian points on the palm of the hand even when using the device 200.

Figure 76 shows an example of an integrated system that combines the first embodiment (Figures 34 to 39) and the second embodiment (Figures 40 to 46) of the invention relating to the system (and method) for identifying Pacinian points. By combining the invention relating to the system (and method) for identifying Pacinian points in this way, it is possible to configure an integrated identification system (and method).

The upper left part of Figure 76 shows a first embodiment of the invention relating to a Pacinian point identification system (and identification method), and the lower left part shows a second embodiment. In the first embodiment in the upper left part, the subject's Pacinian points are identified through a "linear" "measurement" using a linear guide (reference number 604 in Figures 36 and 37), as shown as "XY position discovery."

Meanwhile, in the second embodiment shown in the lower left part of Figure 76, "AI learning" is performed using "big data" (corresponding to steps S710 to S740 in Figure 45), and the learning results go through "AI calculations" by an "AI system" to identify the subject's Pacinian points, as shown as "XY position discovery" (corresponding to steps S712, S722, S732, S742, and S750 in Figure 46).

After that, a 2D jig or 3D jig is produced through the "stamping" and "photographing" steps common to both embodiments. In the first embodiment (FIGS. 34 to 39), "stamping" and "photographing" refer to marking with a marker or the like to produce the support jig, and the subsequent photographing. In the second embodiment (FIGS. 40 to 46), "stamping" and "photographing" refer to marking with a point printing device 711 equipped with a photographing function, and the subsequent photographing (S760).

After that, it is possible to proceed to the process of producing not only the 2D jig (transparent plate 622) of the first embodiment (FIGS. 34 to 39) but also the 3D jig (palm mold 748) of the second embodiment (FIGS. 40 to 46), and produce the 3D jig (palm mold 748). It is also possible to proceed from the process relating to the second embodiment (FIGS. 40 to 46) to the process of producing the 2D jig (transparent plate 622) of the first embodiment (FIGS. 34 to 39), and produce the 2D jig (transparent plate 622). In this way, by making it possible to produce a 2D jig (transparent plate 622) that can be produced relatively inexpensively by planar printing, and a 3D jig (transparent plate 622) that requires relatively high cost due to three-dimensional modeling, it is possible to give the user a choice. This allows for a more diverse tool selection, with financially well-off users choosing a 3D tool (transparent plate 622) and less financially well-off users choosing a 2D tool (transparent plate 622).

[Invention relating to an automatic device design system]
Next, a system and a method for automatically designing the above-mentioned instruments (such as the instrument 1 and the instrument 200) will be described. Note that, here, the automatic design system and the automatic design method will be described using the ring model type instrument 200 as an example.

First, the reason why an automated design method such as the one described below is necessary is to maximize the effect of the device 200. In other words, the size of the palm of each person's hand is different, and the position of the Pacinian corpuscles is also different for each person. Therefore, in order to maximize the effect of the device 200, it is necessary to provide a device 200 that is tailored to the size of each individual user (personalized).

For example, when making custom-made clothing, certain dimensions such as shoulder width are measured and a pattern is created. In the automated design system described here, the dimensions of predetermined parts of each person's hand and the size of the hand are measured, and an instrument that accurately matches the position of the Pacinian corpuscles is designed.

(Embodiments of the invention relating to an automated design system)
First, the position of the Pacinian point on the palm of the subject's hand and the positions of the knuckles of the fingers are measured, and the measurement result data is stored in a storage device of a computer (not shown) (step (S) 800). Of these measurements, the measurement of the position of the Pacinian point can be performed, for example, in the same manner as the position detection method described above (FIG. 13(b)). In the photographic image of FIG. 47(a), the position of the measured Pacinian point (point P) is marked with a marker.

When measuring the positions of finger joints, the positions of the joints and the length of each part are determined for the little finger as shown in FIG. 47(a). For example, the position of the widthwise center part at the base of the distal joint (first joint, distal joint) on the tip side is determined as K1. The position of the widthwise center part at the base of the middle joint (second joint, middle joint) is determined as K2, and the position of the widthwise center part at the base of the proximal joint (third joint, proximal joint) is determined as K3.

Furthermore, the position of the center of the raised part (hypothenar part) on the little finger side of the palm is determined as K4. Furthermore, the length of the distal phalanx is determined as L1, the length of the middle phalanx as L2, and the length of the proximal phalanx as L3.

These positions and lengths can be measured, for example, as positions and lengths on a coordinate system with the origin being any part of the palm (such as the tip of the little finger, the tip of the middle finger, the tip of the thumb, or the center of the wrist). Alternatively, the positions and lengths can be measured in other ways without being limited to this.

Figure 47 (b) shows the positions of the hand (here, the left hand) when gripping a prototype (here, designated by the reference symbol 200) that has the same function as the device 200. By passing the little finger and ring finger through the ring portion 230 and gripping the device 200, the grip line D formed by the little finger and palm is roughly on an arc.

Based on the results of measuring the positions of the Pacinian points and the finger joints, it is possible to create a bone model (hand bone model) 810 as shown in FIG. 48 (S810). This bone model 810 is a three-dimensional object, and is created, for example, using a 3D printer. In addition, when creating the bone model 810, the positions of K1 to K4 and the lengths of L1 to L3 described above are reflected.

For example, for the little finger, the position of the widthwise center at the base of the distal phalanx (first joint, distal joint) on the tip side is designated as K1. The position of the widthwise center at the base of the middle phalanx (second joint, middle joint) is designated as K2, and the position of the widthwise center at the base of the proximal phalanx (third joint, proximal joint) is designated as K3. Furthermore, the position of the center of the base of the metacarpal bone on the little finger side of the palm is designated as K4.

Furthermore, the length of the distal phalanx is defined as L1, the length of the middle phalanx as L2, the length of the proximal phalanx as L3, and the length of the metacarpal bone as L4.

To avoid complicating the explanation and illustrations, explanations of other fingers and other parts of the palm (the ball of the foot, the base of the four fingers, etc.) will be omitted, but their positions and lengths are also measured in the same way, and the measurement results are reflected in bone model 810. Then, a bone model 810 tailored to the hand of the person being measured is obtained.

When creating the bone model 810, the measurement results of the Pacinian points and the finger joints are converted into numerical information and entered into a numerical form in a spreadsheet, for example, and then imported from the spreadsheet into the 3D CAD. The link between the spreadsheet and the 3D CAD can be performed, for example, in the same manner as described above. In the 3D CAD, calculation processing is performed, such as multiplying the basic bone model information by a predetermined coefficient according to the subject's conditions (for example, age, sex, physical build information, etc.). The calculation results of the 3D CAD are imported into a 3D printer, which then forms the bone model 810. Note that the creation of the bone model 810 can be omitted if an instrument that satisfies the subject can be created by measurement using a dummy grip 880, which will be described later.

Next, a 3D scanner is used to 3D scan the shape of the subject's hand, and 3D scan data is obtained (S820, FIG. 49). The obtained 3D scan data is, for example, imported into a numerical sheet of a spreadsheet software, and imported into 3D CAD in the same manner as when creating a bone model 810. FIG. 49 shows an example of 3D scan data displayed on a monitor device. In 3D CAD, calculation processing such as multiplication by a predetermined coefficient according to the subject's conditions (for example, age, sex, physical information, etc.) is performed. The calculation results of the 3D CAD are imported into a 3D printer, and a hand model (hand model) 820 is formed by the 3D printer (S830). This hand model 820 is a hollow three-dimensional object. In addition, the hand model 820 matches the bone model 810 in terms of the positions K1 to K4 of the joints, the length of the joints, etc. Here, in FIG. 49, the display image is inverted to match the orientation of the hand to FIG. 47(a).

Figure 50 shows an image of the created bone model 810 and hand model 820 placed side by side. Also, Figure 51 shows an image of the bone model 810 covered by the hand model 820. Here, in Figures 50 and 51, the displayed images are inverted to match the orientation of the hand to that of Figure 47(a).

By creating the hand model 820 in this manner, a 3D model that matches the shape of the subject's hand and the shape of the bones and combines the hand and bones can be obtained. Note that, like the creation of the bone model 810 described above, the creation of the hand model 820 can be omitted if an instrument that satisfies the subject can be created by measuring with a dummy grip, which will be described later.

Next, as shown in FIG. 52, a dummy grip 880 is prepared that is similar in size (external dimensions) to the instrument (200) and that imitates the instrument (200), and the subject is asked to grasp this dummy grip 880. Then, while the subject is grasping the dummy grip 880, a 3D scanner is used to 3D scan the shape of the subject's hand (S840). At this time, the dummy grip 880 is grasped so that a gap 882 is formed between the dummy grip 880 and the little finger.

The 3D scan data acquired by the 3D scan is imported into a numerical form in, for example, a spreadsheet software, and then imported from the spreadsheet software into 3D CAD (S850). In the 3D CAD, the thickness (particularly width and diameter, etc.) of the little finger and ring finger when gripping the instrument (200) is measured based on the imported 3D scan data (S860). In the 3D CAD, calculation processing is performed, such as multiplying the basic hand information by a predetermined coefficient according to the conditions of the person being measured (for example, age, sex, physical information, etc.) (S870).

Then, from the measurement results, various conditions such as the size (diameter) of the holes of the little finger ring 231 and the ring finger ring 232 in the ring portion 230 of the device 200 are determined, and the determined sizes are used as the design values of the ring portion 230 (S870). Also, on the 3D CAD, the relationship between the position of the Pacinian point (point P) and the bent little finger and ring finger is determined, and the determined contents are used as the design values of the dimensions of each part (S870).

The reason for using a dummy grip 880 instead of the instrument 200 when performing 3D scanning is to make it easier to measure the little finger and ring finger by preventing the 3D scan data from becoming overly complex.

Figure 53 shows the subject's hand with the little finger and ring finger bent. The 3D scan data acquired when creating the bone model 810 is used with the parameters changed so that the little finger and ring finger are bent as shown in Figure 53. The data showing the little finger and ring finger bent to form a gap 882 (see Figure 52) is then used to design on the 3D CAD as described above.

Furthermore, the data relating to the main body 210 and the data relating to the ring 230 described above are combined to determine the positional relationship between the main body 210 and the ring 230 (S880). Then, based on the information derived from the triangular mesh polygon data, the dimensions of each part of the instrument 200 (a prototype is shown in the figure) are determined as shown in Fig. 54. Here, the symbols in Fig. 54 represent the dimensions of the following parts.
M1: Center-to-center distance between the main body 210 and the ring portion 230 M2: Width of the main body 210 (X-axis direction)
M3: Inner diameter of the little finger ring 231 M4: Height of the instrument 200 (Z-axis direction)
M5: Width of ring portion 230 (Z-axis direction)
M6: Distance from the ring portion 230 to the tip of the pressing portion 220 (Z-axis direction)
M7: Distance from the main body 210 to the tip of the pressing part 220 (Z-axis direction)
M8: Diameter of the R portion of the pressing part 220

Based on the design data obtained in this manner, the main body 210 and the ring portion 230 are produced using a 3D printer or the like (S890). The device 200 is then assembled using the main body 210, the pressing portion 220, and the ring portion 230 as components. As a result, a custom-made device 200 in which the pressing portion 220 accurately hits the Pacinian point is provided to the subject.

Figure 55 shows that the shape and size of the device 200 can be changed by this design method. For example, a design change is made to a standard size device 200 (standard product, shown in solid line) to make it custom-made, and the position of the ring portion 230 (only the pinky ring is shown here) is moved away from the main body portion 210, as shown by the two-dot chain line. The ring portion 230 is not necessarily formed at a right angle to the main body portion 210, and may be formed at an angle to the main body portion 210 depending on factors such as the positional relationship between the finger joints and the main body portion 210.

By adopting the automated design system and automated design method described above, it becomes possible to custom-make the device 200. This makes it possible to provide the optimal size of the device 200 according to individual differences and the child's growth.

In addition to redesigning the device 200 each time, such as every year or every few years, it is also possible to adopt a provision format such as the following. First, multiple devices 200 with different sizes and relative positions of each part are manufactured and stored in a store or business. Then, at set intervals (every year or every few years, for example), the palm of the user's hand is measured (3D scanning may be performed). Then, based on the results of the measurements, an appropriate device 200 is selected and loaned to the person being measured.

Figure 77 shows an example of an integrated system of the invention relating to the Pacinian point identification system (and identification method) shown in Figure 76 and an invention relating to an automatic instrument design system. By combining the invention relating to the Pacinian point identification system (and identification method) and the invention relating to the automatic instrument design system in this way, it is possible to configure an integrated instrument and support jig manufacturing system (and manufacturing method).

"Pacini point identification" shown in the upper left of Figure 76 is the process of identifying the position of the Pacini point. This "Pacini point identification" corresponds to measuring the position of the Pacini point (S800 in Figure 56) in the embodiment related to the automatic design of the instrument (Figures 47 to 56). The latter "dummy measurement" corresponds to the process of scanning the hand holding the dummy grip 880 with a 3D scanner as shown in Figure 52 (S840 in Figure 56).

The latter stage, "automated design," corresponds to the process of importing the 3D scan data into 3D CAD via a spreadsheet software, and determining the size and positional relationships of each part while performing calculations in the 3D CAD (S850 to S880 in FIG. 56). And "production" corresponds to the process of forming the device 200 using a 3D printer (S890 in FIG. 56).

The lower part of Figure 77 shows an integrated system related to the Pacinian point identification system (and identification method) shown in Figure 76. The "Photographing" on the far left of the lower part corresponds to photographing in searching for the location of Pacinian points (search, first embodiment) and photographing in identifying the location of Pacinian points by an AI system (second embodiment). Furthermore, the processes from "stamp" to "2D jig" or "3D jig" are the same as the common processes of the integrated system shown in Figure 76.

[Modifications Related to Ring Portion 230]
Next, modified examples of the ring portion 230 in the above-mentioned ring model device 200 will be described. All of the modified examples of the ring portion 230 described here can be manufactured by integral molding of synthetic resin. In addition, they can be manufactured by the above-mentioned automated design.

The function of the ring model device 200 as described above can be achieved in the same way even if the shape of the ring portion 230 is changed. FIG. 58 illustrates various shapes that can be adopted for the ring portion 230. FIG. 58(a) illustrates a device 200 similar to that shown in FIGS. 31 and 32, which, as described above, has a ring portion 230 on which two rings (pinky ring 231 and ring finger ring 232) are formed. In the following, this type is considered to be the standard type for the ring portion 230.

The device 200 shown in FIG. 58(a) is inverted with the pressing portion 220 facing forward compared to the device 200 shown in FIG. 32, and the positional relationship between the main body portion 210 and the ring portion 230 is also slightly different.

In contrast to this standard type, FIG. 58(b) shows a type of ring part 230b in which the partition wall between two rings (pinky ring 231 and ring finger ring 232) has been partially removed, connecting the internal spaces of the two rings 231 and 232 into one. Also, FIG. 58(c) shows a type of ring part 230c that has only one ring (pinky ring 231 in this case).

Figures 58(d)-(f) show a type in which the tip side of the ring parts 231a-231c in Figures 58(a)-(c) is cut diagonally (here, so that it becomes lower from the ring finger side to the little finger side) with respect to the Y axis (shown in Figure 58(a)), and the shape of the ring (231 or 232) is an open arc shape (W-shape or U-shape). And, instruments 200b-200f equipped with these types of ring parts 230b-230f can also prevent rotation around the Z axis (left and right rotation), and can exert the same position fixing function as the instrument 200 of this embodiment.

[Modification of the pressing portion 220]
Next, a description will be given of various modified examples of the pressing portion 220 of the device 200. Note that the same parts as those of the device 200 of the second embodiment are given the same reference numerals, and the description will be omitted as appropriate.

(First Modification of Pressing Portion 220)
In the first embodiment described above, it was explained that it is preferable to form a space around the contact portion 21 (Pacinian ball) of the pressing portion 20 of the instrument 1 so as not to stimulate sensory receptors other than the Pacinian corpuscles when the contact portion 21 (Pacinian ball) is sunk into the palm by about 1 mm to 15 mm (preferably 3 to 10 mm) as shown in Fig. 5. In relation to this, in the instrument 200A of the second embodiment shown in Fig. 59, the radius R of the spherical pressing portion 220A (particularly the contact portion 221) is optimized.

For example, if the entire (or most) part of the pressing portion 220 (here 220A) or the contact portion 221 (here 221A) is spherical, if the radius of the sphere is too large, the arc (spherical surface) of the contact portion 221A that comes into contact with and presses against the palm of the hand will also be large. As a result, the arc (spherical surface) that presses the Pacinian point will become larger, and the shape of that part will approach a flat surface. As a result, if the Pacinian point is set to a small radius of about 1 mm, it will be difficult to press the Pacinian point accurately with the appropriate amount of force.

Furthermore, if the radius of the contact portion 221A is too small, the pressing force will cause the pressing portion 220 (here, 220A) to sink too far into the palm, causing the user to feel pain. In this case, it will be difficult to transmit an appropriate pressing force to the Pacinian corpuscles. Furthermore, the size of the palm of each individual, and each element (attribute) such as adult, child, woman, and man, will usually differ, and the radius at which the pressure of the contact portion 221 (Pacinian ball) is appropriately felt will also differ.

Considering these factors, it is most effective for the contact portion 221A to have a spherical shape, as in the devices 1 and 200 described above. In addition, in the example of FIG. 59, the radius R of the contact portion 221A is set to any value within the range of R4 to 10. Within this range, for example, when the radius is set to R4, the contact portion 221A suitable for a female child (girl) is obtained. Furthermore, when the radius is set to R10, the contact portion 221A suitable for an adult male (adult man) is obtained. According to the inventors' research, for an average-sized Japanese adult female, R7 to 8 is suitable, and for a larger-sized person, R8 to 10 is suitable. Furthermore, for a smaller-sized person than the average-sized Japanese female, R4 to 7 is suitable.

(Second Modification of Pressing Portion 220)
60(a) and (b) show an enlarged view of the pressing portion 220B according to the second modification. In this pressing portion 220B, the contact portion 221B formed integrally with the pressing portion 220B has a raised convex shape. The contact portion 221B has a stepped shape (here, a two-step shape), and has a semispherical first contact portion 221B1 (the tip of the pressing portion 220B) having a relatively small radius, and a tapered second contact portion 221B2 having a relatively large radius. In the example of FIG. 60, the pressing portion 220B has a three-step shape as a whole, including the second contact portion 221B2. In addition, in FIG. 60(a) and (b), the angle of the taper in the second contact portion 221B2 changes slightly in the middle, so a ring-shaped line is drawn in the middle of the second contact portion 221B2.

As shown in Fig. 60(b), the base end side of the pressing portion 220B (the side of the shaft portion 222 shown in Fig. 31) is molded flat, and the shaft portion 222 (Fig. 31) is fixed to this flat portion. The portion of the pressing portion 220B excluding the first contact portion 221B1 and the second contact portion 221B2 is molded into a sphere, and the radius R _A of this portion is, for example, about R4 to R10.

The radius R _B of the first contact portion 221B1 is about R0.5 to 5 (a smaller value than R _A ). The tip side of the second contact portion 221B2 is a small-diameter portion that is continuous with the first contact portion 221B1, and its radius R _C (the horizontal radius in the figure) is the same as the radius R _B of the first contact portion 221B1. The base end side of the second contact portion 221B2 is a large-diameter portion, and its radius R _D is a smaller value than R _A.

By making the shape of the pressing portion 220B a multi-stage sphere as shown in Figures 60(a) and (b), it is possible to directly apply a stronger stimulation to the exact Pacinian point using the first contact portion 221B1 at the tip. Furthermore, the first contact portion 221B1 at the tip allows the pressing portion 220B to be firmly inserted into the palm of the hand. As a result, slippage of the contact portion 221B (Pacinian ball) is suppressed, and the contact portion 221B (Pacinian ball) can be prevented from slipping and moving even when the user changes posture during exercise.

The shape of the second modified example allows the first contact portion 221B1 to function like a pivot, and it is possible to continue to press the Pacinian point accurately without shifting its position. As mentioned above, the Pacinian corpuscles are sensory receptors with a size of about 1 mm, so it is important to prevent the position of the pressing portion 220B from shifting in order to accurately stimulate the Pacinian point. In addition, if the diameter of the first contact portion 221B1 is too small, there is a possibility that excessive pain will be felt when pressing. For this reason, it is preferable that the radius R _B is about R0.5 to 5.

In addition, in this second modified example, the portions of the pressing portion 220B other than the first contact portion 221B1 (the portion closer to the base end than the first contact portion 221B1, particularly the second contact portion 221B2) are larger than the first contact portion 221B1. Therefore, when the palm is pressed by the first contact portion 221B1, the second contact portion 221B2, etc., which is located closer to the base end than the first contact portion 221B1, functions as a stopper. This prevents excessive sinking or pressure from occurring when pressing.

It is also possible to determine the appropriate degree of pressure by the contact area between the pressing portion 220B (particularly the first contact portion 221B1 and the second contact portion 221B2) and the palm. It is also possible to determine the size of the first contact portion 221B1 and the second contact portion 221B2 so that this contact area falls within an appropriate value (or range).

The shape of the first contact portion 221B1 (the tip of the pressing portion 220B) may be a shape other than a spherical shape (including a curved shape), such as a cone or pyramid, so long as it is not excessively sharp. In FIG. 60, auxiliary lines (auxiliary lines) connecting the tip to the base end are drawn at 90 degree intervals in the circumferential direction on the outer peripheral surface to make it easier to understand the three-dimensional shape of the pressing portion 220B. FIG. 61(a) also shows an example of a first contact portion 221B11 that is cone-shaped and has a curved tip (which may be a spherical tip). In this case, too, the curved surface of the first contact portion 221B11 can be a curved surface equivalent to a spherical surface with an R of 0.5 to 5.

Furthermore, the shape of the tip of the first contact portion 221B1 is not limited to a spherical shape (including a curved shape), and for example, as shown in FIG. 61(b) of the first contact portion 221B12, the whole may be cylindrical with a flat tip. Furthermore, the tip of the first contact portion 221B12 shown in FIG. 61(b) may be curved (or may be a true sphere). In this case, too, the curved surface of the first contact portion 221B12 may be a curved surface equivalent to a true sphere of R0.5 to 5. Although not shown, the tip of the first contact portion 221B1 may be a polyhedron (including a regular polyhedron), a sphere with needles (including a curved surface, a sphere with needles is also called a "star sphere"), or the like.

(Third Modification of Pressing Portion 220)
Fig. 62 shows a schematic diagram of a pressing part 220C according to the third modified example. This pressing part 220C has a height adjustment function. As described above, the expansion range of the joint motion range changes depending on the pressure applied to the Pacinian corpuscles. When the pressure is changed to be gradually increased (for example, when the level is changed in the order of weak, medium, and strong), it is known that the joint motion range is expanded most widely when the pressure is set to a strong level up to a certain pressure.

Figure 63 shows, from top to bottom, photographic images of lateral bending in the following cases: when using bare hands (nothing is being held); when an instrument (grip) for pressing Pacinian corpuscles is held with a weak level of strength as in the first and second embodiments; when the instrument (grip) is held with a medium level of strength; when the instrument (grip) is held with a strong level of strength; and when the instrument (grip) is held with a strength that exceeds the strong level (strongest).

As shown in Figure 63, starting with the bare hand (top image), the subject's left arm reaches a position closer to horizontal in the order of low, medium, and strong levels. However, when comparing the image of the strongest level (bottom image), where the gripping force is stronger than the strong level, with the strong level just above, the subject's left arm is no different from the strong level. As a result, the arm position is slightly higher at the strongest level compared to today's level.

In this way, when the pressure exceeds the strong level, even if the force applied to the device 200C from the user's fingers (here the little finger and ring finger) is increased and the maximum pressure that the user can exert is applied, the range of motion of the joint does not increase beyond the strong level. Therefore, by changing the amount of protrusion of the pressing part 220C from the main body part 210C for each user and adjusting the height, it is possible to obtain the same level of pressure as when the user exerts maximum force, even if the user does not exert maximum force, and it is possible to efficiently maximize the effect (the effect of expanding the range of motion of the joint) according to the individual, without requiring excessive force.

Figure 62 shows a schematic example of a mechanism for maximizing such effects. A male thread is formed on shaft 222C connected to pressing portion 220C, and shaft 222C is screwed into nut 242 fixed to main body 210C. For example, when a user picks up pressing portion 220C and rotates it forward or backward around the axis, shaft 222C moves forward or backward relative to main body 210C (moves forward or backward along the Z axis), changing the amount of protrusion of pressing portion 220C relative to main body 210C. A variable protrusion amount mechanism is formed by shaft 222C and nut 242, and the variable protrusion amount mechanism changes the amount of protrusion of pressing portion 220C.

By employing such a mechanism, the height of the pressing portion 220C can be adjusted, and appropriate pressure generation function can be realized for each user. Note that the mechanism for adjusting the height of the pressing portion 220C is not limited to the one illustrated in FIG. 62, and can be modified in various ways. Also, the ring portion is not illustrated in FIG. 62.

(Fourth Modification of Pressing Portion 220)
Figures 64(a) and (b) are schematic diagrams showing a pressing portion 220D according to a fourth modified example. In the example shown in Figures 64(a) and (b), the height of the pressing portion 220D is adjustable, similar to the example shown in Figure 62. However, in the example shown in Figures 64(a) and (b), the pressing portion 220D is integrally formed with the shaft portion 222D and has the same diameter as the shaft portion 222D. In addition, the shaft portion 222D is molded in a stepped shape and has a flange portion 246 that protrudes in the radial direction.

A columnar space 248 is formed in the main body 210D. The shaft 222D is inserted into the space 248 so that it can be displaced freely in the axial direction, with the flange 246 positioned within the space 248. A female thread is formed in a predetermined area on the inner peripheral surface of the space 248, and the disk 250 is screwed into the main body 210D.

A coil spring 252 is interposed between the disk portion 250 and the flange portion 246 of the shaft portion 222D. The portion of the shaft portion 222D closer to the disk portion 250 than the flange portion 246 is inserted into the coil spring 252. Each end of the coil spring 252 is in contact with the disk portion 250 and the flange portion 246.

A groove (driver groove) 254 for a flathead screwdriver is formed in the center of the plate surface of the disk portion 250 opposite the coil spring 252. A lid 256 is attached to the main body portion 210D, and this lid 256 closes one end of the space portion 248 (the upper end in Figures 64(a) and (b)) in an openable and closable manner. The lid 256 can be removed from the main body portion 210D by the user pulling it up, for example by hooking it with their fingers, and can be inserted into the space portion 248 to close the space portion 248 (it is removable).

As shown in FIG. 64(a), when the pressing portion 220D is not subjected to an external force in the axial direction, the shaft portion 222D protrudes from the main body portion 210D due to the elastic restoring force of the coil spring 252. The positions of the pressing portion 220D and the shaft portion 222D are determined by the flange portion 246 engaging with the main body portion 210D.

Figure 64 (b) shows a state in which the pressing portion 220D is subjected to an external force in the axial direction. In this case, the coil spring 252 is compressed and elastically deformed via the flange portion 246, and the shaft portion 222D sinks into the space portion 248 depending on the magnitude of the external force. Then, the amount of protrusion of the pressing portion 220D from the main body portion 210D (the height of the pressing portion 220D) becomes smaller (the height becomes lower) compared to the state in which no external force is applied, as shown in Figure 40 (a).

In FIG. 64(b), the shaft portion 222D is in contact with the disk portion 250, and the pressing portion 220D and the shaft portion 222D are stopped by the shaft portion 222D hitting the disk portion 250. In other words, when the shaft portion 222D is retracted, the disk portion 250 functions as a stopper that determines the limit of the amount of retraction.

In this way, in the example shown in Figures 64(a) and (b), it is possible to adjust the height of the pressing portion 220D (change the amount of protrusion) in the same way as in the example shown in Figure 62. Furthermore, in the example shown in Figures 64(a) and (b), it is possible to easily generate a strong level of pressure by elastically changing the amount of protrusion using the elastic restoring force of the coil spring 252.

In the example shown in Figures 64(a) and (b), a removable lid 256 is provided on the main body 210D, and a driver groove 254 is provided on the disk portion 250. The lid 256 is screwed onto the main body 210D and contacts the coil spring 252. For these reasons, the elastic restoring force of the coil spring 252 can be changed by removing the lid 256 from the main body 210D and using a flathead screwdriver to rotate the disk portion 250 forward or backward around the axis.

Therefore, for example, even if the user grips the device 200D with the same force, it is possible to finely vary the pressing force of the pressing portion 220D depending on the position of the disk portion 250 and the characteristics (such as the spring constant) of the coil spring 252.

The mechanism for adjusting the height of the pressing portion 220D is not limited to the example shown in Figures 64(a) and (b) and can be modified in various ways. Also, the ring portion is not shown in Figures 64(a) and (b).

(Fifth Modification of Pressing Portion 220)
65 is a schematic diagram of the pressing part 220E according to the fourth modified example. In this fourth modified example, the pressing part 220D can be stored in the main body part 210D as shown by the arrow M, and can be pulled out from the main body part 210D. This prevents the pressing part 220E protruding from the main body part 210E from getting caught on the surroundings in the bag (not shown) when the user carries the device 200E in the bag or the like.

In the example of FIG. 65, the shaft portion 222E is connected to the main body portion 210E via the hinge portion 260 inside the main body portion 210E. Various hinge portions 260 can be used. For example, it is possible to use a hinge portion 260 having a mechanism (such as a ratchet mechanism) that can stop the pressing portion 220E and the shaft portion 222E at least in two stages: a state in which the pressing portion 220E and the shaft portion 222E are protruding from the main body portion 210E, and a state in which the pressing portion 220E and the shaft portion 222E are stored inside the main body portion 210E.

In addition, in order to make it easier to remove the stored pressing portion 220E from the main body portion 210E, it is also possible to make at least a portion of the pressing portion 220E exposed from a hole or notch in the main body portion 210.

[Modifications Related to the Main Body 210]
Next, a description will be given of various modified examples of the pressing portion 220 of the device 200. Note that the same parts as those of the device 200 of the second embodiment are given the same reference numerals, and the description will be omitted as appropriate.

(First Modification of the Main Body 210)
Fig. 66 is a schematic diagram of a main body 210F according to a first modified example. In the example of Fig. 66, the main body 210F is a swing type that tilts its posture with respect to the shaft 222F (and the pressing portion 220F). The main body 210F can be tilted with respect to the shaft 222F (and the pressing portion 220F). The shaft 222F is connected to the main body 210F via a hinge portion 262. Various types of hinge portions 262 can be used.

For example, it is possible to adopt a hinge portion 262 that can stop the main body portion 210F relative to the shaft portion 222E by frictional force. It is also possible to adopt a hinge portion 262 that has a mechanism (such as a ratchet mechanism) that can stop the shaft portion 222E in three or more stages.

In the example of FIG. 66, the relative positional relationship between the ring portion 230F and the main body portion 210F can also change due to the swing of the main body portion 210F. In order to achieve this, for example, it is conceivable to construct the ring portion 230F from a flexible material such as synthetic resin, so that the joint portion (reference number omitted) with the main body portion 210F can elastically deform in response to the swing of the main body portion 210F.

(Second Modification of Main Body 210)
Fig. 67 is a schematic diagram of a main body 210G according to a second modified example. In the example of Fig. 67, a little finger stopper 264 capable of locking a little finger protrudes from the main body 210G. This little finger stopper 264 is designed to be locked by the tip (first joint) of the little finger that has passed through the ring portion 230 (not shown in Fig. 67). The little finger stopper 264 may be integrally molded with the main body 210G, or may be formed separately from the main body 210G and attached later.

[Third embodiment of the device]
Next, a third embodiment of the tool will be described with reference to Fig. 69. Fig. 69 shows a schematic diagram of a tool 300 (grip) of the third embodiment. The tool 300 of the third embodiment is of a ring model type, similar to the tool 200 of the second embodiment. Therefore, in the following, the same parts as those of the tool 200 of the second embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

(Configuration of the device 300)
The instrument 300 according to the third embodiment, like the instrument 200 described above, applies pressure stimulation to the exact position of the Pacinian corpuscles to expand the range of motion of the joint. Furthermore, the instrument 300 of this embodiment has a vibration function that vibrates the pressing part 320. Inside the main body 310 of the instrument 300, a vibration motor 312, a computer 314, and a built-in battery 316 are provided. Here, Fig. 69 is a schematic diagram of the instrument 300, and the devices built into the instrument 300 are also shown by solid lines.

The vibration motor 312 includes a vibrator (weight) 340, and together with the vibrator (weight) 340 constitutes a vibration generating unit. The vibration motor 312 rotates and displaces the vibrator 340 in an eccentric state, and generates vibrations in the XY plane by changing the position of the center of gravity. A pressing unit 320 is attached to the vibration motor 312 via a connection unit 322. Although not shown in the figure, the vibration motor 312 may be of a type in which the vibrator 340 is built into a case and is unitized. In this case, the vibration motor 312 can be used as a vibration generating unit.

The vibration motor 312 is controlled by the computer 314 and rotates to generate vibrations at a predetermined frequency (e.g., 150 to 400 Hz). The vibrations generated by the vibration motor 312 are transmitted to the pressing portion 320, which also vibrates in the same manner. The vibration frequency of the vibration motor 312 is changed under the control of the computer 314. Power for the vibration motor 312 and the computer 314 is supplied by the built-in battery 316.

Inside the main body 310, the vibration motor 312 is surrounded by a vibration-proof case 342. The vibration-proof case 342 has the function of preventing the vibrations generated by the vibration motor 312 from being transmitted to the main body 310.

Indicated by reference numeral 344 in FIG. 69 is a lid that covers the opening of the vibration isolation case 342 and through which the connection portion 322 passes. Furthermore, indicated by reference numeral 346 in FIG. 69 is a memory device 350 provided in the main body portion 310. The memory device 350 can store data for controlling the vibration motor 312, etc.

The storage device 350 may be an external memory of the computer 314 or a memory device (such as an SD card) that the user can remove from the device 300. The built-in memory of the computer 314 may also be used to store information.

With this type of instrument 300, the pressing portion 320 can be vibrated in a direction intersecting (in the example of FIG. 69, a direction perpendicular to) the direction in which it protrudes from the main body portion 310 (the Z-axis direction). Therefore, in addition to achieving the same effect as the previously described instrument 200, it is possible to add vibration to the Pacinian points. And compared to the previously described instrument 200, it is possible to selectively apply pressure stimulation to the Pacinian corpuscles more effectively.

One of the characteristics of Pacinian corpuscles is that they are receptors that sense pressure and vibration. Furthermore, Pacinian corpuscles receive vibrations of 100 to 300 Hz, and are most sensitive to vibrations around 200 Hz. By taking advantage of these characteristics of Pacinian corpuscles and actively applying pressure stimuli, it is possible to further improve the effectiveness of using the instrument 300.

Furthermore, since it is possible to change the frequency of vibration, it is possible to generate vibrations and pressure (pressure changes) in accordance with, for example, the tempo, rhythm, melody, and strength of music (including voice). Stimuli such as music can then be input to the body via the instrument 300 and the Pacinian corpuscles and transmitted to the brain. The brain can simultaneously perceive auditory information from the ears and somatic information from the Pacinian corpuscles. Furthermore, it is possible to cause the instrument 300 to function as a communication tool with the user via vibrations and pressure (pressure changes). It is also possible to communicate using the palm of the hand, where the Pacinian corpuscles are located, as if it were a second ear.

[Fourth embodiment of the device]
Next, a fourth embodiment of the instrument will be described with reference to Fig. 70. Fig. 70 shows an instrument 400 (grip) of the fourth embodiment. The instrument 400 of the fourth embodiment is a ring type instrument similar to the instrument 200 of the second embodiment (Fig. 31) and the instrument 300 of the third embodiment (Fig. 69). Therefore, in the following, the same parts as those of the instrument 200 of the second embodiment or the instrument 300 of the third embodiment (Fig. 69) are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

(Configuration of the device 400)
The instrument 400 according to the fourth embodiment, like the instruments 200 and 300 described above, applies pressure stimulation to the exact position of the Pacinian corpuscles to expand the range of motion of the joint. Furthermore, like the instrument 300 according to the third embodiment, the instrument 400 according to the present embodiment has a vibration function that vibrates the pressing part 420. In addition, the instrument 400 has a usage state detection function (state information detection function) that detects information related to the usage state of the instrument 400, such as gripping force and position (usage state information as state information).

The main body 410 of the device 400 is equipped with a vibrator 412, a computer 414, and an internal battery 416. Of these, the vibrator 412 may be any of a variety of general vibrators that vibrate when electricity is applied. The vibrator 412 may be, for example, a piezoelectric element that generates vibrations in the Z-axis direction.

A vibration stick (vibrating body) 444 is attached to the vibrator 412. The vibration stick 444 may be in the shape of a round bar or a square bar. Here, it is possible to use the vibrator 412 as the vibration unit, or to use a combination of the vibrator 412 and the vibration stick 444 as the vibration unit.

The vibration stick 444 is inserted concentrically into the cylindrical connection part 422 and penetrates the connection part 422 and the pressing part 420. In the fourth embodiment of the device 400, the connection part 422 is fixed so as not to be displaced relative to the main body part 410. The vibration stick 444 is loosely inserted into the connection part 422 and the pressing part 420 and vibrates in the axial direction (Z-axis direction) within the connection part 422 and the pressing part 420. When the tip of the vibration stick 444 is displaced in a direction away from the main body part 410 (downward in FIG. 70), it protrudes somewhat (for example, less than 1 mm) from the pressing part 420.

Regarding the relationship between the pressing portion 420 and the vibration stick 444, for example, a part of the vibration stick 444 (here, the lower end part) can be incorporated into the pressing portion 420, and the pressing portion 420 can be configured to include a part of the vibration stick 444.

The vibrator 412 is controlled by the computer 414 and rotates to generate vibrations at a predetermined frequency (for example, 150 to 400 Hz). The vibrations generated by the vibrator 412 are transmitted to the vibration stick 444, which also vibrates in the same manner. The vibration frequency of the vibrator 412 can be changed by the control of the computer 414. Power for the vibrator 412 and computer 414 is supplied by an internal battery 416 (a button-type battery in this case).

Inside the main body 410, a position sensor 446 and a pressure sensor 448 are provided as a usage state detection unit (and a state detection unit). These detect information related to the usage state, such as the amount of movement and gripping force, when the tool 400 is being held and used by a user.

Of these, the position sensor 446 is for detecting the position of the instrument 400 in space. For example, an acceleration sensor that detects changes in acceleration can be used as the position sensor 446. By integrating the output of the acceleration sensor, speed and displacement information can be obtained. The output signal of this position sensor 446 (an acceleration signal in this case) is input to the computer 414, which can then calculate the amount of displacement of the instrument 400.

The pressure sensor 448 detects the reaction force (grip force) when the device 400 is held between the palm and the fingers (pinky and ring fingers) and the pressing part 420 is pressed against the palm. The computer 414 calculates the pressure based on the output of the pressure sensor 448.

The outputs of the position sensor 446 and the pressure sensor 448 are used for the calculations of the computer 414, and the results of the calculations of the computer 414 are stored in the memory device 450. As the memory device 450, various memory devices provided in the instrument 400 can be used.

The memory device may be an external memory of the computer 414 or a memory device (such as an SD card) that the user can remove from the device 400. It is also possible to use the built-in memory of the computer 414. It is also possible to store data for controlling the vibration motor 312 in advance in the storage device 450.

The device 400 also has a built-in communication circuit unit (not shown) that outputs status information to an external device (not shown) (external output) and inputs various information sent from an external device (external input). This communication circuit unit may be built into the computer 314, or may be externally attached to the computer 314. Communication for external output and external input may be performed by a wired connection, for example, via a USB cable, or may be performed by a wireless connection, for example, via Wi-Fi or Bluetooth (registered trademark).

Examples of external devices include smartphones, mobile phones, tablet terminals, notebook PCs, desktop PCs, e-book readers, wearable computers, and portable game consoles. The external output destination may be a server device of a service provider connected via a communication network such as the Internet.

When the instrument 400 is connected to these external devices (not shown), the detection results of the position sensor 446 and pressure sensor 448 described above can be output to the outside, and calculations related to usage status information such as pressure and displacement amount can be performed in the external device.

In addition to providing the same effects as the above-mentioned instruments 200 and 300, such an instrument 400 is capable of detecting a state using a position sensor 446 and a pressure sensor 448. Furthermore, by providing the instrument 400 with a display device such as a liquid crystal display, it is possible to display the results of state detection and to display information based on the results. Furthermore, by using a communication function, it is possible to link with external devices.

[Invention relating to application to user information provision systems]
Next, the application of the device 1, device 200, device 300, device 400, etc. of each embodiment described above to a user information provision system and the multi-functioning suitable for application to a user information provision system will be described. Note that in the various exercise promotion systems described below, the device 1, device 200, device 300, device 400, etc. of each embodiment can be appropriately selected and used, but when there is a particularly suitable device, the description will be given using the suitable device.

(First embodiment of the user information providing system according to the invention)
First, a first embodiment of the invention of a user information providing system will be described with reference to Fig. 71. Fig. 71 shows a schematic configuration of an exercise promotion system 1000 considered as a user information providing system according to the first embodiment. The exercise promotion system 1000 is a system that assumes that multiple people (e.g., several people to tens of millions of people) can perform exercise (hereinafter, referred to as "grip exercise") using equipment (not limited to any equipment).

In the exercise promotion system 1000 shown in FIG. 71, the management center's operating system (labeled "Health Education System" in FIG. 71) 1010, an information processing device (not shown) in a photography studio 1020, and communication terminals 1030 owned by individuals are connected via a communication network 1040.

The management center's operating system 1010 is constructed using a server device (not shown). The server device may be installed, for example, by the operator of the exercise promotion system 1000. The operating system 1010 manages the exercise promotion system 1000 using a CPU (central processing unit), ROM, RAM, etc.

The CPU is a processor that executes various types of arithmetic processing. The ROM is a non-volatile storage unit in which control programs such as the BIOS (Basic Input Output System) and the OS (Operating System) that cause the CPU to execute various types of arithmetic processing are stored in advance. The RAM is a volatile or non-volatile storage unit that stores various types of information, and is used as a temporary storage memory (work area) for various types of processing executed by the CPU. The operating system 1010 performs processing for managing the exercise promotion system 1000 by having the CPU execute various control programs that are stored in advance in a storage unit such as the ROM.

Here, the operating system 1010 may be configured from one server device or multiple server devices with distributed functions. The operating system 1010 may also be referred to as an "operating device", etc.

The information processing device of the photography studio 1020 may be a general desktop PC, a notebook PC, or a server device. As described below, the information processing device of the photography studio 1020 enables videos captured by a camera in the photography studio 1020 to be distributed to each individual via the communication network 1040. The information processing device of this photography studio 1020 may be a smartphone or a tablet terminal that is an information processing device with an integrated camera. Furthermore, the information processing device of the photography studio 1020 may be integrated with a server device in the management center's operating system 1010.

The communication terminal 1030 owned by each individual may be a smartphone, a mobile phone, a tablet terminal, a notebook PC, a desktop PC, a television receiver, an e-book reader, a wearable computer, or a portable game console. Examples of the communication network 1040 include the Internet, a LAN, a WAN, a public telephone line, a base station, a mobile communication network, and those connected to each other via a gateway (including the so-called cloud).

In this exercise promotion system 1000, an instructor 1022 uses equipment (e.g., equipment 400) in a photography studio 1020 to perform exercises (grip exercises) while stimulating the Pacinian point. Examples of types of grip exercises include stretching, yoga, muscle training, and the like, which are included in the uses mentioned above. Further examples include model movements for various sports, rehabilitation movements, and the like.

The movements of the instructor 1022 are filmed as a video in the filming studio 1020. The video of the instructor 1022 is then transmitted to a communication network 1040 and distributed to a large number of communication terminals 1030 via the communication network 1040 (step (S) 1000). Various general processes can be used for the process from filming to distribution of the video.

For example, it is possible to perform processing for distribution (so-called live distribution) at the same time as shooting, or to distribute the video after a specified time has passed after shooting. It is also possible to edit the video after shooting and then distribute it. Furthermore, the video may be distributed by transferring the video data to the management center operating system 1010 or storing it in the management center operating system 1010, and then distributing it to the communication terminal 1030.

Application software (so-called app) that can display distributed videos and input information related to the videos is installed on each individual's communication terminal 1030. In FIG. 71, the portion with the letters "APP" superimposed on the communication terminal 1030 shows that application software is installed on the communication terminal 1030.

Each individual also owns an implement (e.g., implement 400) and performs the grip exercise by imitating the instructor 1022 while watching the video displayed on the communication terminal 1030 (S1010). Each individual who is a user of the implement (e.g., implement 400) becomes a participant in a grip exercise that is performed simultaneously around the world (a global simultaneous grip exercise), and a large-scale grip exercise (large-scale grip exercise) can be performed by 10 million people around the world (approximately 20 million people in FIG. 71) at the same time while watching the communication terminal 1030.

In this way, a network is formed by the communication terminal 1030, the equipment (e.g., equipment 400), and the brain of each individual that receives the neurotransmission signals from the equipment (e.g., equipment 400). This network is then used to build an exercise promotion system 1000 that aims to maintain and improve each individual's athletic ability.

The application software installed on the communication terminal 1030 also has a function of displaying, for example, the number of individuals (number of participants) taking part in the large-scale grip exercise on the communication terminal 1030. To perform such display, the operating system 1010 collects information (status information) obtained via the communication terminal 1030 via the communication network 1040 and the application software of the communication terminal 1030 (S1020).

In addition to the image of the instructor 1022, information on the standard exercise state (such as the tempo and rhythm of the exercise, the size of the arm movements, etc.) (also called "reference exercise information," "standard exercise information," "instructional information," or "model information") can be converted into text or numbers and output (including audio output) to the communication terminal 1030 and presented to the user.

Furthermore, the reference exercise information can also be presented through vibrations and up-down movements (movement of the pressing part 420 in the protruding direction) generated by the device 400. In this case, for example, the reference exercise information is presented to the user by having the device 400 generate vibrations and up-down movements synchronized with the rhythm, tempo, etc. of a standard exercise.

In this way, by presenting reference movement information via device 400, it is possible to generate signals that are transmitted from the Pacinian corpuscles to the brain. Furthermore, when reference movement information from video or music and reference movement information transmitted from device 400 are simultaneously combined (synchronized) and output, the visual and auditory information and information from the Pacinian corpuscles are transmitted to the user's brain together. This makes it possible to transmit information in a novel manner that has never been seen before.

In the exercise promotion system 1000, a multi-functional device 400 with vibration and information collection functions is used to detect the condition of each individual when a large-scale grip exercise is performed. The results of the condition detection are received from the device 400 by a communication terminal 1030, and are transmitted from the communication terminal 1030 to the management system 1010 of the management center via a communication network 1040. Here, it is also possible to give the device 400 a function that allows it to communicate with the management system 1110 via the communication network 1040.

In the operating system 1010, various internal systems are operated, and exercise promotion information as user information is transmitted to the communication terminal 1030 (S1030). Although not shown in the figure, examples of the various internal systems of the operating system 1010 include a grip monitor control system 1060, a video distribution system 1070, and a pressure/position movement analysis system 1090.

Here, the "grip monitor control system," "video distribution system," and "pressure/position movement analysis system" can also be referred to as, for example, a "grip monitor control unit," a "video distribution unit," and a "pressure/position movement analysis unit."

Of these, the grip monitor control system 1060 is a system that controls the content displayed on the display device when the tool 400 is equipped with a display device. Information for display on the tool 400 may be transmitted from the grip monitor control system 1060 to the tool 400 via the communication terminal 1030, or may be transmitted without passing through the communication terminal 1030.

The video distribution system 1070 is a system that controls the distribution of videos to the communication terminal 1030. The pressure/position movement analysis system 1090 is a system that receives and analyzes the status information sent from the instrument 500 via the communication terminal 1030.

In the management system 1010, for example, the pressure/position movement analysis system 1090 analyzes information (usage status information as status information) obtained from each individual's communication terminal 1030, and calculates statistical values (for example, total, average, standard deviation, rank, etc.) for data from a large number of people (big data). Furthermore, the calculation results are classified by attributes such as gender and age, and correlations with the information of each individual are found. Then, comparative information such as rank and deviation value is calculated for each individual's information, and the obtained calculation results are sent to the relevant individual.

Information based on the calculation results (user information) is displayed, for example, on the communication terminal 1030 or the device 400 and notified to the relevant individual (S1040). Examples of information displayed (presented) on the communication terminal 1030 or the device 400 include the number of individuals (number of participants) taking part in the large-scale grip exercise described above, and the rankings described above. This information indicates the position of each individual within the large group.

In this way, by sending and informing the relevant individual of their position among a large number of people, it is possible to stimulate a competitive spirit among participants in the large-scale grip exercise and motivate them to continue the exercise. Here, the process of using big data to generate information to send back to individuals may be performed using statistical machine learning using AI, deep learning, or the like.

By displaying the number of participants and rankings as mentioned above, it is possible to combine grip exercise with an element of play. In other words, these days, due to dual-income households and the COVID-19 pandemic, it has become difficult to find time to go to a gym or other facility to exercise. As a result, there is an increasing demand for exercise that can be done alone in a small space such as at home.

Therefore, by performing the grip exercise with a large number of people at the same time and informing the participants of the number of participants, it is possible to motivate each individual to perform the grip exercise. For example, even if a person performs the grip exercise alone in his or her own place at the same time every day, the person can realize that he or she is performing the grip exercise together with many other people, which can encourage the person to continue the grip exercise. The information (user information) presented to the user is not limited to information that is presented to the user instantly (in real time) based on collected information. For example, information related to past exercise history may be presented in units of one day, one week, one month, or one year. This also applies to the various embodiments and modified examples described below.

As described above, reference exercise information that serves as a model for the user's exercise is transmitted, and the user can perform the exercise based on the model, so that the user can obtain information about appropriate exercise before performing the exercise. After that, the operating system 1010 can obtain information on the acceleration, speed, and position of each individual's hand movements (usage status information as status information) and provide personal user information as feedback to the user. This mutual communication allows the user to reflect on themselves (introspect, reflect, reflex, etc.) and learn about the relationship between their own body and exercise. This type of user information provision system can also be called an "exercise education/reflection system."

The exercise promotion system 1000 of this embodiment can be said to combine grip exercise with an element of play. There are various definitions of play. For example, according to Roger Caillois's "Classification of Play," play is competition, chance, simulation, dizziness, or play. Also, according to Johan Huizinga's "The Concept of Play," play is a spontaneous act or activity that is carried out within a clearly defined range of time and space.

The exercise promotion system 1000 of this embodiment enables large-scale grip exercises that are suitable for a variety of play activities as a result of the distribution of video and the corresponding mutual communication with individual status information. It is also possible to combine the distribution of video with audio encouraging participation in the grip exercise, and depending on the situation, it is also possible to encourage participation in the grip exercise by audio alone.

Such an exercise promotion system (user information provision system) 1000 can also be used as follows. First, the reference exercise information presented to the user is information conveying exercise programs tailored to each age group (assuming ages range from children to those in their 90s) created from the standpoints of physical education pedagogy, kinesiology and movement science, and sports psychology. This reference exercise information is presented by live broadcasting from a filming studio 1020, or by video distribution using videos stored in a server device. The above-mentioned "exercise program" is made up of exercise components such as rhythm, tempo, accurate position, and form.

In order to optimize a user's exercise in line with the reference exercise information, the rhythm and tempo of the exercise program are essential components. For this reason, it is necessary to present the exercise program to the user in a way that is tailored to the physical abilities of each age group and individual. According to the inventors' knowledge, in many cases, users can easily increase their motivation and grasp an appropriate exercise speed by matching their exercise (timing) to music that combines melody with rhythm and tempo. The user exercises in line with a video or the like that matches the exercise program that has been created with these points in mind.

After the user starts exercising, in the process of collecting status information, the status of the equipment 400, such as the position data, movement acceleration data, and changes in gripping force of the equipment 400, is transmitted to the operating system 1010 by the status information detection means (such as the position sensor 446 and pressure sensor 448) mounted on the equipment 400.

Then, the operating system 1010, based on the analysis program, presents and informs the user of the analysis results. In the analysis, if it is determined based on the various state information transmitted that the user is performing an incomplete movement or an exercise that does not meet the standard, an analysis is performed to determine which of the aforementioned movement components, such as tempo, rhythm, accurate position, and form, are involved. Then, based on the analysis results, a learning task (ideal learning task) for improving the movement of the corresponding user is selected, and the corresponding user's exercise task is derived based on predetermined derivation conditions that integrate quantitative and qualitative conditions of the movement.

The derived results are presented to the user, who can then learn about his or her own condition on a personal level and begin to think about what needs to be improved. The user then continues to exercise using the equipment 400 with the goal of seeing improvements in their exercise. This cycle of user encouragement and user behavior can be called a cycle of education and reflection.

(Second embodiment of the user information providing system according to the invention)
Next, a second embodiment of the user information providing system according to the invention will be described with reference to Fig. 72. Note that the same reference numerals are used for the same parts as those in the fourth embodiment of the equipment and the first embodiment of the exercise promotion system according to the invention, and the description thereof will be omitted as appropriate.

As a user information provision system according to the second embodiment, an exercise promotion system 1100 has been considered. Like the exercise promotion system 1000 according to the first embodiment, this exercise promotion system 1100 is a system that assumes that a large number of people (e.g., 10 million people) will perform grip exercise.

In the exercise promotion system 1100 shown in FIG. 72, the management center's operating system (written as "Health Education System" in FIG. 72) 1110 and the communication terminals 1030 owned by each individual are connected via a communication network (not shown). Although not shown, the communication network can be the same as the communication network 1040 of the exercise promotion system 1000 according to the first embodiment. In addition, the operating system 1110 can also use a hardware configuration similar to that of the operating system 1010 according to the first embodiment.

Figure 72 shows a case where the device 500 is used in the exercise promotion system 1100. The device 500 shown in Figure 72 includes a vibrator 412, a computer 414, an internal battery 416, a position sensor 446, and a pressure sensor 448, similar to the device 400 described in the fourth embodiment of the device. The device 500 also has a vibration function and a state detection function.

The device 500 has a built-in communication circuit unit (not shown) that allows the above-mentioned status information to be output externally. This communication circuit unit (not shown) can also have the same configuration and function as the device 400 described above. Here, the device 500 can also be provided with a function that allows it to communicate with the operating system 1110 via the above-mentioned communication network (1040 referring to FIG. 71).

Furthermore, the device 500 is equipped with a display device 560, as shown in the lower left side of FIG. 72. The display device 560 is disposed on the outer surface of the main body 410, and is capable of displaying information such as status information and user attributes under the control of the computer 414. In FIG. 72, the device 500 is depicted on the right side of the bottom row, showing a schematic representation of the internal equipment of the main body 410, and the device 500 is depicted on the left side, showing a schematic representation of the outside of the main body 410. In other words, the internal and external configurations of one device 500 are depicted side by side on the left side at the bottom row of FIG. 72.

In FIG. 72, the names "total exercise result diagnosis system" and "real-time correction system" are separately listed for the operating system 1110. In this operating system 1110, various internal systems operate, and exercise promotion information as user information is sent to the communication terminal 1030. As examples of the various internal systems of the operating system 110, FIG. 72 shows, from the left, a grip monitor control system 1160, a video distribution system 1170, a music vibration Hz tempo command system 1180, and a pressure/position movement analysis system 1190.

Of these, the grip monitor control system 1160 is a system that controls the content displayed on the display device 560 of the tool 500, similar to the grip monitor control system (not shown) described above. The video distribution system 1170 is a system that controls the distribution of videos to the communication terminal 1030, similar to the video distribution system (not shown) described above.

The music vibration Hz tempo command system 1180 is a system that transmits information corresponding to the tempo of music (including background music for videos) distributed to the communication terminal 1030 to the communication terminal 1030. Furthermore, the pressure/position motion analysis system 1190 is a system that receives status information sent from the instrument 500 via the communication terminal 1030, similar to the pressure/position motion analysis system (not shown) described above.

In the management system 1110, similar to the management system 1010 according to the first embodiment, the information obtained from each individual's communication terminal 1030 is analyzed, statistical values are calculated, and the calculation results of comparative information such as rankings and deviation scores are transmitted to the relevant individual. Information based on the calculation results is displayed, for example, on the communication terminal 1030 and notified to the relevant individual.

More specifically, a video of the grip exercise filmed in a film studio 1020 (referring to FIG. 71 ) is distributed to individuals' communication terminals 1030 by a video distribution system 1170 of the operating system 1010. Individuals who receive the video perform the grip exercise in accordance with the video displayed on the communication terminal 1030. Since the video is distributed to a large number of individuals, a large-scale grip exercise can be performed.

Musical pieces are distributed along with the video of the grip exercise. The music vibration Hz tempo command system 1180 of the operating system 1010 transmits command information to each individual's communication terminal 1030 to drive the vibrator 412 of the device 500 in accordance with elements that affect the melody of the music, such as the tempo, rhythm, melody, and dynamics.

The vibrator 412 vibrates in response to elements such as the tempo, rhythm, and strength of the music, and the vibration of the vibrator 412 is transmitted to the vibrating stick 444. The vibration of the vibrator 412 is then transmitted to the individual holding the device 500 via the vibrating stick 444. Note that the vibration generating mechanism is not limited to the type in which the vibrator 412 vibrates the vibrating stick 444, and it is also possible to employ a vibration generating mechanism that vibrates the pressing portion 220, as shown in FIG. 69, for example.

Next, information related to the output of the position sensor 446 and the pressure sensor 448 is transmitted to the operating system 1010 via the communication terminal 1030. In the operating system 1010, the pressure/position motion analysis system 1190 analyzes the individual's motion status. Then, information is transmitted from the grip monitor control system 1160 to the communication terminal 1030, and the device 500 displays the information received from the communication terminal 1030 on the display device 560.

Examples of information displayed on the display device 560 include diagnostic results showing the intensity and duration of exercise, suggestions for modifying the exercise method (increasing the duration of exercise, making larger movements, etc.), and other information that may be useful to the individual. In the example of FIG. 72, the display device 560 of the device 500 displays the pressure with which the device 500 is gripped (1.2 kg), the number of grips (120), and the age estimated from the grip strength (36 years old).

In addition, the information to be notified to the individual may be based on the detection results (calculation results) of the walking, jogging, etc. speed, which may be compared with previously stored personal information to determine the physical condition of the individual, suggesting that the individual take a break or speed up. Furthermore, it is also conceivable that the vibrations generated by the equipment 500 may be used to give a command to change the tempo of the exercise.

In this way, it is possible to provide useful information (such as suggestions, guidance, or advice) to an individual performing grip exercise via the operating system 1110. The output of useful information may be performed by either the tool 500 or the communication terminal 1030, or by both. When suggestions or guidance are output by both the tool 500 and the communication terminal 1030, the displayed content or audio output content may be the same, or may be different.

(Third embodiment of the user information providing system according to the invention)
Next, a third embodiment of the exercise promotion system according to the invention will be described with reference to Fig. 73. Note that the same reference numerals are used to designate parts similar to those of the above-mentioned devices (device 400, device 500, etc.) and the second embodiment of the exercise promotion system according to the invention (exercise promotion system 1100, Fig. 72), and descriptions thereof will be omitted as appropriate.

As a user information provision system according to the third embodiment, an exercise promotion system 1200 has been considered. Like the exercise promotion system 1100 according to the second embodiment, this exercise promotion system 1200 also promotes exercise by individuals through mutual communication of information related to grip exercise.

First, it is said that grip strength is proportional to overall muscle strength. Furthermore, decreased physical flexibility is a cause of falls in aging. For example, at the beginning of "The Effects of Habitual Exercise on Health - Using Grip Strength as an Indicator" by Nakamaru Aoi et al., it is explained that "Grip strength is reported to represent the overall health of the body. It has been reported that the lower the grip strength, the higher the incidence of decline in physical function, impaired activities of daily living, and the higher the mortality rate (Newman et al. 2006)."
Additionally, the Ministry of Education, Culture, Sports, Science and Technology (2015) also reported the results of a survey on physical fitness and athletic ability in fiscal year 2014, measuring grip strength as an indicator of muscle strength and examining trends in changes associated with age.
https://www.mext.go.jp/sports/b_menu/toukei/chousa04/tairyoku/kekka/k_detail/1368152.htm

Based on this idea, the exercise promotion system 1200 according to this embodiment uses the information collection function of the device such as device 400 or device 500 to collect data related to grip strength (step (S) 1200). This exercise promotion system 1200 can employ a hardware configuration similar to that of the exercise promotion system 1000 according to the first embodiment.

In the exercise promotion system 1200 according to this embodiment, for example, the pressure applied by the little finger and ring finger of the individual 1210 gripping the tool 500 is detected and measured by the pressure sensor 448 using the tool 500. The measurement results are then stored in the storage device 450 of the tool 500. Based on this pressure information, it is possible to calculate grip strength (grip strength) information of the individual gripping the tool 500. When converting pressure to grip strength (grip strength), for example, it is possible to multiply the pressure value by an integer or to multiply it by a predetermined coefficient.

Then, the position of the instrument 500 is detected and measured by the position sensor 446 built into the instrument 500. As described above, an acceleration sensor, for example, can be used as the position sensor 446, and the amount of displacement can be calculated by integrating the output of the acceleration sensor. By defining a predetermined origin as described below, the information on the amount of displacement can be converted into position information.

These measurement results relating to grip force and position are stored in the storage device 450 of the device 500. In addition, a menu of measurement exercises is determined in advance and stored in the device 500 and the operating system 1110. This "measurement exercise" refers to the exercises that are the subject of measurement (measurement target exercises). Examples of the measurement exercise menu include forward bending and side bending.

When performing the measurement exercise, a file containing the measured grip force data (grip force data) and position data (position data) is transferred via the communication terminal 1030 to the management center's operating system ("Health Education System" using FIG. 72) (S1210). The management center's operating system uses the position data of the tool 500 to set an origin and calculates the value of the index based on this origin (S1220).

In the example of Figure 73, the origin for an individual is set at the center of the upper waist (around the navel), and the angle during side bending centered on the origin is set as one index (θ). Then, the instrument 500 measures the index value θ° of the angle between the direction of the arm (here, the right arm) when stretched straight up from the floor on which the individual is standing (the direction of the arm before side bending) and the direction of the arm during side bending.

In addition, a horizontal index (X) and a height index (Y) are also set. In the example of Figure 73, the horizontal displacement of the hand position (horizontal displacement in the direction of lateral bending) is set to the index X value X1. Furthermore, the index Y value of the height from the floor of the hand before lateral bending is set to Y0, and the height from the floor of the hand during lateral bending is set to Y1.

These indices are indices that indicate the flexibility of the individual who performed the grip exercise. For example, the greater the angle value θ° during lateral bending, or the greater the horizontal displacement value X1, the higher the flexibility of the individual can be determined. Also, the smaller the calculation result of Y1/Y0, the higher the flexibility of the individual can be determined.

Data on a large number of people regarding these indicators is collected in advance along with data (attribute data) such as age and gender, and AI learning is performed on the collected data for the purpose of calculating age. Then, based on the results of the AI learning, the age is calculated from the data on each indicator collected from the individual, and the calculated age is displayed on the equipment 500 (or communication terminal 1030) of the individual who performed the grip exercise as an estimated physical age (S1230).

Furthermore, the management center's operating system (operating system 1110 using FIG. 72) notifies the individual who performed the grip exercise by displaying on the equipment 500 (or communication terminal 1030) the name and contents of the exercise program for improving flexibility through exercises using the equipment 500 (S1240).

The management center's operating system (operating system 1110 using FIG. 72) collects subsequent information on the individual who was the subject of the notification (S1250). It then judges whether the notified exercise program is being performed as a habit based on the detection results of the position sensor 446 and pressure sensor 448. It then references the values of each index to judge whether flexibility has improved (S1260), and based on the judgment result, displays the judgment result on the display device 560 of the equipment 500 (or the communication terminal 1030) (S1270).

This display notifies the individual as to whether or not their flexibility has improved (whether or not the rejuvenating effect has been observed). It is also possible to combine the display with audio, or to notify the effect of the grip exercise by audio alone.

(Fourth embodiment of the user information providing system according to the invention)
Next, a fourth embodiment of the exercise promotion system according to the invention will be described with reference to Fig. 74. Note that the same parts as those in the above-mentioned devices (device 400, device 500, etc.) and the second embodiment of the exercise promotion system according to the invention (exercise promotion system 1100, Fig. 72) are given the same reference numerals, and the description thereof will be omitted as appropriate.

As a user information provision system according to the fourth embodiment, an exercise promotion system 1300 has been considered. Like the exercise promotion system 1100 according to the second embodiment, this exercise promotion system 1300 promotes the exercise of each individual through mutual communication of information related to grip exercise. Furthermore, this exercise promotion system 1300 prevents a decrease in the vibration sensitivity of the Pacinian corpuscles, allowing the effects of grip exercise to be continuously exerted.

First, as mentioned above, one of the characteristics of Pacinian corpuscles is that they are receptors that sense pressure and vibration. Furthermore, Pacinian corpuscles receive vibrations of 100 to 300 Hz, and are most sensitive to vibrations around 200 Hz. However, when vibrations of a constant frequency are continuously applied, they are initially sensitive to the vibrations, but if this state is maintained, the Pacinian corpuscles adapt to the vibrations and it becomes difficult to perceive them.

In addition, when gripping the device 500 and performing gripping movements, the gripping force changes with the movement of the body, and the pressure transmitted to the Pacinian corpuscles changes. Therefore, if the gripping force changes, the Pacinian corpuscles do not adapt, and the effect of using the device 500 is maintained.

The exercise promotion system 1300 of this embodiment focuses on these points and applies them further to prevent the Pacinian corpuscles from adapting. More specifically, the frequency and pressure transmitted to the Pacinian corpuscles are changed in accordance with the tempo and rhythm of the music to prevent the Pacinian corpuscles from adapting. In addition, the pressure transmitted to the Pacinian corpuscles can be constantly changed by changes in gripping force and vibration during gripping movements.

As shown in FIG. 74, in the exercise promotion system 1300, the management center's operating system 1310 is equipped with a tempo/rhythm/emphasis extraction system 1330 and a tempo/rhythm command system 1340. Of these, the tempo/rhythm/emphasis extraction system 1330 has the function of extracting information on tempo, rhythm, and sound dynamics from any sound source (such as music, shown here with the reference number 1320) stored in a storage device (not shown), and converting it into data. Elements of the sound source, such as the tempo, rhythm, and dynamics, affect the melody.

The tempo/rhythm command system 1340 performs data conversion on the tempo, rhythm, and strength data extracted by the tempo/rhythm/emphasis extraction system 1330, and creates vibration mode information to instruct the instrument 500. The vibration mode information includes information such as the frequency of the vibrations generated by the instrument 500.

The tempo/rhythm command system 1340 transmits vibration mode information to the personal communication terminal 1030 via a communication network (not shown). The communication network may be the same as the communication network 1040 of the exercise promotion system 1000 according to the first embodiment. The tempo/rhythm command system 1340 also transmits sound source information relating to the music of the sound source to the communication terminal 1030. Examples of sound source information include information identifying the music and sound source data of the music itself.

The communication terminal 1030 transmits commands to the instrument 500 using pre-installed application software (so-called app) and transmits vibration mode information to the instrument 500. The communication terminal 1030 outputs music or the like, which is the sound source, based on the above-mentioned sound source information. An individual who possesses the communication terminal 1030 can recognize the sound source through hearing. The instrument 500 generates vibrations and changes the vibration frequency based on the vibration mode information. By changing the vibration frequency, it is possible to change the vibration intensity.

With this type of exercise promotion system 1300, it is possible to continuously change the stimulation of the Pacinian corpuscles by the gripping exercise and the sound source 1320. The individual using the device 500 can simultaneously perceive in the brain the auditory information from the ears and the somatic information from the Pacinian corpuscles. The individual using the device 500 can then perform the gripping exercise more comfortably due to the synchronization of the auditory information and the somatic information.

The first (FIG. 71) to fourth (FIG. 74) embodiments of the user information provision system (exercise promotion system in this case) described above can also be described as follows. For example, according to these exercise promotion systems 1000, 1100, 1200, and 1300, it is possible to provide reflection (introspection, reflection, reflexivity, etc.) to individuals who use or possess the equipment by transmitting (uploading) personal information via the equipment (equipment 400, equipment 500, etc.) and receiving (downloading) information about the individual via the equipment or communication terminal 1030.

Furthermore, as explained in the first embodiment (FIG. 71), reference exercise information that serves as a model for the user's exercise is transmitted, and the user can exercise based on the model, so that the user can obtain information about appropriate exercise before exercising. Also, the reference exercise information can be presented via vibrations or up-down movements (movement in the protruding direction of the pressing part 420) generated by the device (such as the device 400 or 500). In this case, for example, the device (such as the device 400 or 500) can generate vibrations or up-down movements synchronized with the rhythm or tempo of a standard exercise, thereby presenting reference exercise information to the user. In this way, by presenting reference exercise information via the device (such as the device 400 or 500), it is possible to generate signals that are transmitted from the Pacinian corpuscles to the brain.

Furthermore, when reference movement information from video or music and reference movement information transmitted from an instrument (such as instrument 400 or instrument 500) are simultaneously combined (synchronized) and output, the visual information, auditory information, and information from the Pacinian corpuscles are transmitted to the user's brain as a single unit. This makes it possible to transmit information in a novel manner that has never been seen before.

Then, through mutual communication, the exercise promotion systems 1000, 1100, 1200, 1300 obtain information on each individual (usage status information as status information) and provide the user with personal user information as feedback, thereby further enhancing the effect of reflection (introspection, reflection, reflexivity, etc.) in the user. As mentioned above, such a user information provision system can also be called an "exercise education/reflection system".

The information exchanged is personal information, and the information given to the individual (feedback information) reflects the individual's situation, so it can create a situation in which it is as if a personal trainer were making a diagnosis and creating indicators based on an individual's exercise menu, and providing guidance and advice (instruction, etc.). Then, the individual who receives guidance, etc., can recognize that their own exercise method (exercise status) is going well, or that there is a deficit or excess.

Furthermore, by an individual being aware of their own exercise status and continuing to exercise daily while improving their exercise technique, self-improvement can be achieved step by step, and as a result, a spiral up in the way the individual progresses with their exercise can be expected. Furthermore, the mutual communication function that enables such a spiral up can also encourage individuals to want to own (including want to purchase) equipment (such as equipment 400 or equipment 500).

[Other examples of information processed by the device]
Next, another example of information processed by the tool (here, the tool 500) will be described. Note that parts similar to those in the above-mentioned tool (such as the tool 500) and the second embodiment of the exercise promotion system (exercise promotion system 1100, FIG. 72) are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

The device 500 measures grip strength (grip strength) and informs the individual using it of the current grip strength, the number of grips made that day, the duration of the grip exercise, etc. In the example of Fig. 75 (a) and (b), the display device 560 of the device 500 is used as an indicator to inform the individual of the grip strength. Also, the device 500 (or the communication terminal 1030) allows the individual to input and store the most effective grip strength for the individual using it. Then, if a target grip strength (target grip strength) is set, when the grip strength reaches the target value, this is notified. Examples of means for notifying that the target has been reached include the display device 560 and a lamp (LED) of a predetermined color (e.g., green).

As another example, a sensor (health index sensor) that measures health indexes such as blood pressure is incorporated into the device 500, and the measured health index is displayed on the display device 540. Communication is performed with the communication terminal 1030, and the health index is continuously managed by the communication terminal 1030. In this way, health management linked to the communication terminal 1030 becomes possible.

In addition, the information transmitted and received between the appliance (such as the appliance 400 or the appliance 500) and the management center's operating system (operating system 1110 or operating system 1310) is not limited to the information described above. For example, the appliance status information may be appliance failure information, lost information, etc.

Regarding fault information for an appliance (such as appliance 400 or appliance 500), for example, a fault detection unit (condition detection unit) may be provided inside the appliance (such as in various main body parts). If the fault detection unit determines that the electrical circuit (including electronic circuit) inside the appliance is not running normally, a signal to that effect and/or processed information are sent from the appliance to the operating system (operating system 1110 or operating system 1310).

In addition, regarding information on lost appliances (such as appliance 400 or appliance 500), for example, a location information system circuit unit (such as a GPS circuit unit) serving as a status detection unit may be provided within the appliance. Then, via a detection system (not shown), the management center's operating system (operating system 1110 or operating system 1310) transmits the appliance's location information to the communication terminal 1030. The communication terminal 1030 combines and displays map information and location information, and notifies the location of the appliance.

Although each embodiment has been described above, each embodiment can also be described comprehensively as follows. First, exploration of Pacinian points can be performed by various methods, such as a manual exploration method using a pressure point pressing stick or the like (exploration methods such as those illustrated in Figures 13(b) and 40), a mechanical exploration method (exploration methods such as those illustrated in Figures 36 to 38), and an AI exploration method (exploration methods such as those illustrated in Figures 45 to 46).

Furthermore, through various exploration methods, the hand of the user of the instrument is marked with marks indicating the location of the Pacinian points. The marked hand is then used to create a positioning format (creation of a 2D or 3D jig) that enhances the convenience of using the instrument, and for automatic design of the instrument (automatic design as exemplified in Figures 47 to 56).

By using a 2D jig (such as the transparent plate 622) or a 3D jig (such as the palm mold 748) created through the formation of a positioning format (creation of a 2D jig or 3D jig), the user can easily mark the location of the Pacinian points and confirm the location of the Pacinian points. The user can then smoothly begin daily use. As a result, it is possible to promote exercise using the equipment and to encourage the use of the equipment.

This comprehensive approach to instruments can be called an instrument provision system (instrument provision method) that includes a series of processes from instrument supply to utilization and the equipment required for this process.
