<Motion control system>
FIG. 1 is a schematic diagram illustrating a motion control system 100 according to an embodiment. In the present embodiment, the user can move the body according to the instruction according to the pattern of the electrical stimulation while the user is simultaneously applied with the electrical stimulation by the plurality of muscle electrical stimulation devices, thereby more efficiently in a shorter time. It is premised on the exercise program to strengthen muscles. The exercise control system 100 includes a fitness wear 102 equipped with a plurality of electrical stimulation modules, an exercise control device 12, a display control device 104, a mirror display 105, and a posture sensor 107. The mirror display 105 includes a mirror 103 and a display device 106. One set or a plurality of sets are installed in a fitness gym studio with the exercise control device 12, the display control device 104, the mirror display 105, and the posture sensor 107 as a set. The user is provided with fitness wear 102 composed of one set of upper and lower and a pair of arm bands and one set of upper and lower inner wear (not shown). The electrical stimulation module 10 is attached to each location of the fitness wear 102 so that electrical stimulation can be applied to each body part such as a user's abdominal muscles, flank, chest muscles, back muscles, arms, legs, and buttocks. The electrical stimulation module applies electrical stimulation to the user's muscles. Each of the plurality of electrical stimulation modules communicates with the motion control device 12 by short-range wireless communication such as Bluetooth (registered trademark) to transmit and receive information. A motion control program instructed to start execution through communication with the motion control device 12 controls voltage setting and operation in each of the plurality of electrical stimulation modules. The motion control device 12 transmits and receives information to and from the display control device 104 through a local area network via the network cable 108. The display control device 104 is a computer that displays a motion image on the mirror display 105 in accordance with an instruction of a motion control program executed by the motion control device 12.

  The exercise control device 12 is an information terminal operated by an instructor or user of a fitness gym. The exercise control device 12 controls intensity setting and operation for each user and for each electrical stimulation module 10. Since the motion control device 12 functions as a hub of a plurality of electrical stimulation modules, the instructor or the user operates the motion control device 12 rather than setting and operating the plurality of electrical stimulation modules individually. It is more efficient to carry out batch control.

  The motion control device 12 displays on the mirror display 105 via the display control device 104 in a form that synchronizes the explanation of the motion program and the image of the motion with the control of the plurality of electrical stimulation modules. However, considering the delay of wireless communication with each electrical stimulation module, the motion image is not displayed at the timing completely synchronized with the control pulse of the electrical stimulation module, but the image is displayed at a timing delayed by a predetermined period. It may be displayed. The attitude sensor 107 projects infrared rays toward the user standing in front of the mirror display 105, and detects the depth of the user as the object by an infrared sensor and an image sensor that detect the infrared rays reflected from the object, thereby detecting the distance. Get an image. Based on the detection result, the posture of the user is estimated, and an image such as the user's skeleton model based on the estimation result is displayed on the display device 106 of the mirror display 105. The exercise control device 12 includes an ultrasonic probe 13 having an ultrasonic sensor, and can measure fat and muscle thickness such as a user's abdomen.

  Thus, the exercise program in the present embodiment transmits a control signal such as a start signal to the plurality of electrical stimulation modules 10 by the exercise control device 12 and the exercise control program that controls the voltage by the electrical stimulation module 10. However, this is realized in conjunction with a motion control program for displaying a video synchronized with the display device 106. In addition, each user executes the exercise program by moving his / her body using the image displayed on the display device 106 as a model. That is, in this exercise program, the exercise effect can be enhanced by consciously moving the muscle in the opposite direction while applying electrical stimulation to the muscle. For example, such a muscle force load can be increased by performing an exercise (involuntary exercise) that applies a force to stretch the arm consciously while bending the elbow by electrical stimulation (involuntary exercise).

<Mirror display>
The mirror display 105 includes a mirror 103 and a display device 106. The mirror 103 is a mirror that can reflect an image of the whole body of the user on the front side, and has low transmission loss when transmitting infrared rays and radio waves from the back side. The display device 106 is a display device having a screen slightly smaller than the area of the mirror 103 and capable of displaying a large body model corresponding to the whole body of the user, for example, a vertical screen equivalent to a 70-inch display. When the display device 106 is installed on the back side of the mirror 103, the user can visually recognize an image on the screen of the display device 106 that is transmitted through the mirror 103 from the front side of the mirror 103. The mirror 103 and the display device 106 are installed so that at least the upper end of the screen is positioned above the user's line of sight, for example, positioned higher than the average user's height. In the present embodiment, a liquid crystal display device is used as the display device 106. However, in a modification, a general video output device such as an organic EL display device, a projector, and a screen may be used.

<Attitude sensor>
The posture sensor 107 includes an infrared projector that projects infrared rays, an infrared sensor that detects infrared rays reflected by an object, an image sensor such as a CMOS sensor that captures reflected light from the object and acquires an image, a directional microphone, and the like. Consists of including. The attitude sensor 107 measures the distance (depth, depth) of the object by projecting infrared light onto the object and detecting the reflected infrared light by the infrared sensor, and the image sensor detects the reflected light from the object. A distance image is acquired by capturing. As a modification, a back-illuminated ToF distance image sensor in which the attitude sensor 107 is integrated with the display control device 104 may be adopted. The posture sensor 107 is horizontally installed, for example, at a height of about 55 cm from the floor, and detects the posture of the user with an angle of view of about 70 degrees in the horizontal direction and about 60 degrees in the vertical direction. In addition, a recommended exercise space range for allowing the user to fall within the detectable range of the posture sensor 107 is drawn on the floor. The exercise space is installed in a circular shape centered around about 2.5 m from the mirror 103, so that only a user in the exercise space can recognize it, other than a distance range of about 2.5 m from the mirror 103. Excluding detection, only the user around 2.5 m is processed as a detection target. For example, when the user exits a predetermined exercise space and approaches the mirror 103, the screen is blacked out from being detected by the posture sensor 107, while another person passes behind the user (outside the exercise space). Is not detected. In order to prevent false detection, a screen such as a roll screen is installed behind the user, and mirrors are installed so as to face each other along the wall side of the room, so that the mirrors are most separated from each other. The positional relationship. As described above, the detection accuracy by the attitude sensor 107 can be maintained high. In this embodiment, the example using the attitude sensor 107 has been described. In a modified example, a mechanical device such as a gyro sensor or a potentiometer may be attached to the user instead of the attitude sensor 107, or a general detection technique used for motion capture such as fluctuation of a magnetic field by the magnetic sensor may be used. Good.

<Electric stimulation module>
FIG. 2 shows an example of the appearance of an electrical stimulation module that is an example of a muscle electrical stimulation device. FIG. 2A is a plan perspective view of the electrical stimulation module 10. The electrical stimulation module 10 includes a base 21, a housing 20, a first electrode 31, a second electrode 32, a first electrode connection wire 35, a second electrode connection wire 36, a first electrode connection portion 33, and a second electrode connection portion. 34 is mainly provided. The base 21 is a basic member formed in a rectangular shape such as a substantially rectangular shape on which the components of the electrical stimulation module 10 are placed. For example, the base 21 is knitted with a fiber material having shape stability and light weight. It is made of cloth such as taffeta. Since the base 21 is a fiber material, it can maintain a sanitary state by washing and boiling disinfection. The base 21 is provided with slit-like first openings 112a and second openings 112b for inserting the sheet-like first electrode 31 and the second electrode 32 therein. The first electrode 31 and the second electrode 32 inserted into the first opening 112a and the second opening 112b are electrically connected to the first electrode connection part 33 and the second electrode connection part 34 from outside through a hole (not shown). It becomes connected and can be energized. On the outer surfaces of the first electrode 31 and the second electrode 32 on the bottom surface side, the first electrode 31 and the second electrode 32 are respectively printed with conductive ink or formed of a conductive material such as conductive rubber, Electricity is passed between the first electrode 31 and the second electrode 32. The electrical stimulation module 10 includes a pair of positive and negative electrodes, but may include a plurality of sets of electrodes as a modification.

  The housing 20 is disposed at the center of the base 21 on the plane side. However, it is good also as a specification which provides the housing | casing 20 inside the base 21 as a modification. The housing 20 is a box formed of resin, and accommodates a power supply unit, a wireless communication module, and a control circuit. The housing 20 is detachably attached to the base 21. The power supply unit is a secondary battery such as a lithium ion battery, but may be a replaceable primary battery. The power supply unit is electrically connected to the wireless communication module and the control circuit, and supplies power to each. Based on the control according to the motion control program by the control circuit, the first electrode 31 is supplied from the power supply unit via the first electrode connection wire 35 and the first electrode connection unit 33, the second electrode connection wire 36 and the second electrode connection unit 34. A voltage is applied to the second electrode 32. On the plane side of the housing 20, a power button 24 and a pairing button 25 are provided as operation units. The power button 24 accepts a power on / off operation of the electrical stimulation module 10, and the pairing button 25 accepts a wireless communication connection establishment operation. A male hook-and-loop fastener 37 is sewn around the flat side of the base 21. However, in the plane of the hook-and-loop fastener 37, only the outer edge side of the base 21 is sewn to the base 21 of the base in the short direction both ends, and the outer edge seam 42 is not sewn, and the inner edge side is not sewn. A pocket-shaped space is formed inside 42. Even when the electrical stimulation module 10 is attached or detached, even if the electrical wiring such as the first electrode connection wire 35 and the second electrode connection wire 36 installed on the plane side of the base 21 is interfered by other objects, the position moves. It can be accommodated in the pocket of the hook-and-loop fastener 37 and can be prevented from protruding from the electrical stimulation module 10. By attaching the male surface fastener 37 of this figure to the mounting portion (female surface fastener) provided on the back surface of the fitness wear 102, the electrical stimulation module 10 is mounted on the back surface of the fitness wear 102. When not in use, the housing 20 is removed from the base 21 and the hook-and-loop fastener 37 of the electrical stimulation module 10 is attached to the corresponding mounting portion (female hook-and-loop fastener). While being able to wash in this state, it can prevent damaging cloth by a hook-and-loop fastener. As a modification, an NFC (Near Field Communication) tag may be mounted on the electrical stimulation module 10 instead of providing the pairing button 25, and an NFC reader may be mounted on the motion control device 12. In this case, by reading the NFC tag in each electrical stimulation module 10 attached to the fitness wear 102 with an NFC reader, each electrical stimulation module 10 can be authenticated and each can be paired with the exercise control device 12. .

  FIG. 2B is a bottom perspective view of the electrical stimulation module 10. A pair of electrode storage portions 39a and 39b are provided on the bottom surface side of the base 21 formed of taffeta fabric or the like. The electrode storage unit 39 is affixed to the base 21 with a tape 38a, 38b such as polyester tape so that a pile ground such as a sinker pile having a size about 1/3 of the base 21 is bordered. It is formed in a pocket shape. A pocket-like space is formed in the electrode housing part 39, and the first electrode connection part 33 and the second electrode connection part 34 can be inserted from the opening 112. Tapes 38c and 38d such as polyester tape are attached so that the periphery of the base 21 is also edged. Since the pile ground of the electrode storage part 39 is excellent in water retention, it can be impregnated with water. At least a part of the first electrode 31 and the second electrode 32 is close to the user's body side via the electrode storage portion 39 and can contact the inner wear. The 1st electrode 31 and the 2nd electrode 32 are easy to maintain an energized state by contacting the electrode storage part 39 which kept water. A plurality of electrical stimulation modules 10 as described above are attached to the fitness wear 102. The plurality of electrical stimulation modules 10 have individual shapes depending on the attachment site to the fitness wear 102, that is, the corresponding body region. The attachment parts to the fitness wear 102 are a plurality of parts corresponding to the target body parts to which electrical stimulation is to be applied, and correspond to each body part such as the user's abdominal muscles, flank, chest muscles, back muscles, arms, legs, buttocks. It is a place. A corresponding female hook-and-loop fastener for attaching the male hook-and-loop fastener 37 of the electrical stimulation module 10 is sewn to these portions.

  As a modification, the entire planar side of the electrical stimulation module 10 may be covered with a cover formed of an elastomer such as silicon. In another modification, the housing 20 may be mounted on either the first electrode 31 or the second electrode 32 instead of the center of the base 21. In another modified example, the housing 20 may be distributed on the first electrode 31 and the second electrode 32 instead of the center of the base 21. In that case, since the power supply unit, the wireless communication module, and the control circuit are housed in two distributed housings, each housing can be made smaller than the housing 20 in the present embodiment.

  FIG. 3 is a diagram schematically illustrating an appearance and a cross section in the vicinity of an electrode of the electrical stimulation module 10 in a modified example. FIG. 3A is a bottom perspective view of the electrical stimulation module 10 in a modified example. In this modified example, the pair of electrode storage portions 39a and 39b are formed in a shape having a thickness. The electrode storage portions 39a and 39b store the first electrode 31 and the second electrode 32, and a cushion member made of a resin such as polyethylene is packed inside to form a thickness. Polyethylene is suitable as a cushion member because it has good skin contact, low risk of radio wave interference, and low water retention, so that there is no concern about hydrolysis. When the electrical stimulation module 10 is used, it is possible to maintain a good energization state by applying warm water to the electrode housing portions 39a and 39b to retain the water. FIG. 3B is a cross-sectional view of the electrode housing part 39 of the electrical stimulation module 10 according to a modification. The electrode housing part 39 is packed with the first electrode 31 or the second electrode 32 and the cushion member 43. The first electrode 31 and the second electrode 32 are provided on the side that contacts the user's body, and the cushion member 43 is packed between the first electrode 31 and the second electrode 32 and the base 21 so as to fill the height. A first electrode connection wire 35 and a second electrode connection wire 36 are wired between the cushion member 43 and the first electrode 31 and the second electrode 32. In this way, the electrode housing portions 39a and 39b are made thick. Here, if the housing 20 is exposed to the outside, when the fitness wear 102 is brought into close contact with the user's body, it may be caused to interfere with the body and cause pain. In this regard, by making the thickness of the electrode storage portions 39a and 39b thicker than the casing 20, it is possible to secure a space for installing the casing 20 in the thickness direction and make the casing 20 difficult to hit the body, The load when the electrical stimulation module 10 is brought into close contact with the body can be reduced.

  FIG. 4 schematically shows the surface side of the upper-body garment portion of the fitness wear. FIG. 4A shows the front side of the upper-body garment portion 120, and FIG. 4B shows the back side of the upper-body garment portion 120. The upper-body garment portion 120 is formed of, for example, a chemical fiber.

  There are six belts (first belt 116a, second belt 116b, third belt 116c, fourth belt 116d, and fifth belt 116e) on both sides of the upper body garment portion 120, that is, in the vicinity of the user's flank. , A sixth belt 116f) is provided. One end is fixedly attached near the spine on the back side, and the other end is fixedly attached near the flank on the front side. Two belts (seventh belt 116g and eighth belt 116h) are provided on the left and right upper surfaces of the upper-body garment portion 120, that is, the portions corresponding to the vicinity of both shoulders of the user. Each end is fixedly attached to the vicinity of the shoulder, and the other end is fixedly attached to the vicinity of the scapula beyond the shoulder. The above eight belts function as fastening parts for bringing the upper body clothes part into close contact with the body.

  Near the left rectus abdominis muscle of the user, a wear-side ultrasonic probe opening 117 that is opened in order to apply the ultrasonic probe to the user's body is provided. Through this opening, the user can measure the thickness of fat and muscle using an ultrasonic probe while wearing the upper-body garment portion 120. Here, when the user presses the ultrasonic probe from above the inner wear, it is preferable to eliminate the influence of the user's force on the pressing force. Therefore, means (for example, a snap fastener, a hook, a hook-and-loop fastener, etc.) for fixing the ultrasonic probe is provided around the wear-side ultrasonic probe opening 117. As a result, it is possible to stabilize measurement and improve convenience during use. A decoration line 119 is provided between the wear-side ultrasonic probe opening 117 and the fourth belt 116d, the fifth belt 116e, and the sixth belt 116f. The decoration line 119 is a curve that rises substantially vertically from the lower end of the left front body 150 and curves outward toward the armpit. The right front body 151 is also provided with a symmetrical decoration line 119 at a symmetrical position with the fastener at the center of the body as the center. These decoration lines 119 are also boundary lines that divide the installation position of the electrical stimulation module 10 for the rectus abdominis muscle and the installation position of the electrical stimulation module 10 for the oblique abdominis muscle in the upper-body garment portion 120, and the lower end of the decoration line 119 is Designed to match the position of the upper anterior iliac spine in the user's iliac. As a result, the electrical stimulation module 10 positioned between the left and right decorative lines 119 is designed to appropriately hit the rectus abdominis muscle.

  FIG. 5 schematically shows a state where the electrical stimulation module is attached to each attachment portion on the back surface of the upper-body clothing portion of the fitness wear. The electrical stimulation module is mounted on a plurality of mounting portions (not shown) formed by hook-and-loop fasteners corresponding to each muscle to which electrical stimulation is applied. A first electrical stimulation module 10a and a second electrical stimulation module 10b are mounted on the first mounting portion and the second mounting portion corresponding to the abdominal muscles, and the third mounting portion and the fourth mounting portion corresponding to the flank are The third electrical stimulation module 10c and the fourth electrical stimulation module 10d are attached. A fifth electrical stimulation module 10e and a sixth electrical stimulation module 10f are attached to the fifth attachment portion and the sixth attachment portion corresponding to the pectoral muscles, and the eleventh attachment portion and the twelfth attachment portion corresponding to the back muscles are The eleventh electrical stimulation module 10k and the twelfth electrical stimulation module 10l are mounted.

  The first electrical stimulation module 10a and the second electrical stimulation module 10b apply electrical stimulation to the left and right rectus abdominis muscles. The third electrical stimulation module 10c and the fourth electrical stimulation module 10d apply electrical stimulation to the left and right abdominal oblique muscles. The fifth electrical stimulation module 10e and the sixth electrical stimulation module 10f apply electrical stimulation to the left and right pectoral muscles. The eleventh electrical stimulation module 10k and the twelfth electrical stimulation module 101 provide electrical stimulation to the left and right back muscles. In the figure, the upper-body garment portion 120 shows an example in which the electrical stimulation module 10 is arranged mainly for men, but the arrangement and size of the electrical stimulation module 10 may be different for women.

  A wear-side ultrasonic probe opening 117 that is opened in order to apply the ultrasonic probe to the user's body is provided in the vicinity of the user's left abdominal rectus muscle in the upper-body garment portion 120. The electrical stimulation module 10b is also provided with a module-side ultrasonic probe opening 118. Thereby, the user can measure the thickness of fat and muscle using the ultrasonic probe while wearing the upper-body garment portion 120.

  Although the upper body garment portion has been described above, the plurality of electrical stimulation modules 10 are similarly mounted on the lower body garment portion and the armband. Moreover, the user can maintain a comfortable wearing feeling by wearing inner wear under fitness wear. It should be noted that a hygrometer may be provided in the fitness wear so that the environmental humidity or the wear humidity can be detected. In that case, an appropriate current value may be predicted according to the drying condition, and the voltage value as the electrical stimulation may be adjusted to an appropriate value to stabilize the energization to the user's body.

  FIG. 6 is a block diagram showing a functional configuration of the electrical stimulation module 10. The electrical stimulation module 10 includes a power supply unit 22, a control unit 28, and a wireless communication unit 58. The power supply unit 22, the control unit 28, and the wireless communication unit 58 are housed in the housing 20. The control unit 28 includes a power supply control unit 50, an energization detection unit 52, an electrical stimulation control unit 54, and a setting unit 56.

Draw functional blocks. Accordingly, it is understood by those skilled in the art who have touched this specification that these functional blocks can be realized in various forms by a combination of hardware and software. The same applies to each block in FIGS.

  The power supply control unit 50 controls charging of the power supply unit 22 and transmits information indicating the charging state to the exercise control device 12 via the wireless communication unit 58. The energization detection unit 52 detects a resistance value between the first electrode 31 and the second electrode 32 in order to detect whether energization is possible between the electrodes. The energization detection unit 52 detects that energization is possible when the detected resistance value is less than the threshold, and detects that energization is not possible when the detected resistance value is greater than or equal to the threshold. When the electrical stimulation control unit 54 detects that the energization detection unit 52 can energize, the electrical stimulation control unit 54 is connected to the first electrode 31 with a predetermined operation time (for example, 10 minutes) and a predetermined cycle (for example, a frequency of 20 Hz). A set voltage is applied between the second electrodes 32. That is, electrical stimulation is applied to a place where the electrical stimulation module 10 is mounted, for example, the user's abdominal muscles, flank, chest, arms, legs, buttocks, and the like.

  The wireless communication unit 58 receives information on the set voltage from the motion control device 12 via the short-range wireless communication and sends it to the setting unit 56. When the wireless communication unit 58 receives information on the set voltage value or information for instructing increase or decrease in the set voltage value from the exercise control device 12, the setting unit 56 sets the set voltage value to be applied based on the received information. Increase or decrease. Each time the set voltage value is increased or decreased, the electrical stimulation control unit 54 applies a voltage between the electrodes with a new set voltage value, so that the user can feel and confirm the new set voltage value, that is, the exercise intensity. Let As the set voltage value, for example, any value can be set as 100-level intensity. The wireless communication unit 58 increases or decreases the set voltage value when an instruction to increase or decrease exercise intensity is received from the exercise control device 12 during exercise, that is, during voltage application. However, even if an instruction to increase / decrease exercise intensity is received from a device other than the connected exercise control device 12, it is ignored and an instruction to increase / decrease exercise intensity from another device is not followed. This is to prevent the voltage value from being arbitrarily increased or decreased by others other than the user. The wireless communication unit 58 may transmit information indicating the voltage application state by the electrical stimulation control unit 54, that is, information indicating the exercise execution state, to the exercise control device 12.

<Motion control device>
FIG. 7 is a functional block diagram showing a functional configuration of the motion control device 12. The exercise control device 12 includes a control unit 70, a wireless communication unit 71, a wired communication unit 72, and a display unit 74. The control unit 70 includes a display control unit 61, a setting processing unit 63, an information management unit 65, and an ultrasonic measurement unit 66.

  The wireless communication unit 71 transmits and receives information to and from the electrical stimulation module 10 by short-range wireless communication. The wireless communication unit 71 transmits / receives information to / from the plurality of electrical stimulation modules 10. One-way broadcast communication is mainly used, and bidirectional communication by pairing is used as necessary. In the case of bidirectional communication, the information received from the electrical stimulation module 10 may include individual identification information used for user registration and individual management and a unique network address (MAC address). The display unit 74 is a touch panel display device such as a liquid crystal panel or an organic EL panel, and displays information on a screen and accepts an operation input from a user or an instructor.

  The setting processing unit 63 sets the operation content of the plurality of electrical stimulation modules 10 for each user based on an operation input to the display unit 74 by the user or an instructor. The setting processing unit 63 can set different operation contents for a plurality of body parts. The setting processing unit 63 sets the intensity of the electrical stimulation by the muscular electrical stimulation device, that is, the voltage value at any level out of 100 levels as the operation content. The setting processing unit 63 controls the exercise by the electrical stimulation module 10 by transmitting information indicating the operation content to all the electrical stimulation modules 10 via the wireless communication unit 71 by broadcast communication. For example, the setting processing unit 63 controls the electrical stimulation module 10 by transmitting an exercise start signal, a pause signal, an end signal, a voltage value signal, and the like to the electrical stimulation module 10. On the other hand, in order to suppress battery consumption due to communication in the electrical stimulation module 10, it is preferable in terms of design to keep communication to a minimum. For example, the voltage value set in the electrical stimulation module 10 and the data of the exercise control program are stored in the information management unit 65, and the voltage value information is not acquired from the electrical stimulation module 10. Alternatively, it may be determined that the exercise program has ended after a lapse of a predetermined time without transmitting / receiving an exercise end signal.

  The display control unit 61 displays on the display unit 74 the contents related to the execution status of the exercise program, the setting status and the operating status of the electrical stimulation module 10. The display control unit 61 transmits data related to the execution status of the exercise program to the display control device 104 via the wired communication unit 72 in order to display a model image or the like on the display device 106 based on the exercise program. The display control unit 61 displays an image of the human body model, and displays an image that dynamically shows the rhythm of the voltage pulse and the movement of the muscle during exercise in accordance with the control state of the electrical stimulation module 10 via the display control device 104. It is displayed on the display device 106.

  The ultrasonic measurement unit 66 generates a tomographic image of subcutaneous fat and muscle in the body part of the user based on the detection value detected by the ultrasonic probe 13 (ultrasonic sensor) connected to the electrical stimulation module 10. It is displayed on the display unit 74. For example, the measurement is performed for a certain time before the exercise program is started, and an image is displayed on the display unit 74. Since the display control unit 61 displays the tomogram of subcutaneous fat and muscle only to the user himself / herself, the display control unit 61 does not display it on the display device 106 that can be viewed by other users, but displays it only on the display unit 74. As a modification, the display control unit 61 may display the movement of the cross section of the muscle in real time during the execution of the exercise program.

  FIG. 8 is a functional block diagram showing a functional configuration of the display control device 104. The display control device 104 includes a control unit 260 and a communication unit 256. The communication unit 256 is connected to the exercise control device 12 through a local area network or the like, and transmits and receives information. The control unit 260 includes a display control unit 250, a posture estimation unit 252, and a setting processing unit 254. The control unit 260 is also connected to the posture sensor 107 and receives a detection result from the posture sensor 107. The posture estimation unit 252 estimates the user's posture based on the detection result received from the posture sensor 107. The setting processing unit 254 executes the exercise program based on the instruction received from the exercise control device 12 and causes the display device 106 to display the contents through the control by the display control unit 250.

  The display control unit 250 displays a motion model image having the shape of a human body as a model of motion in the exercise program in a small size at the screen corner of the display device 106, thereby instructing the user of the motion with high training effect in an easy-to-understand manner. In addition, the display control unit 250 greatly displays a state object for indicating a movement range for each body part in each motion in the exercise program and an actual motion state for each body part of the user in the center of the screen of the display device 106. The posture estimation unit 252 determines a movement range of the body part from an angle, a movement angle, a distance, and the like formed by each body part such as the extremities, and outputs a predetermined sound when the determined angle or distance satisfies a specified value. This notifies the user that one operation has been performed. The posture estimation unit 252 performs scoring based on whether or not an operation that satisfies the specified value is performed within a predetermined time. The display control unit 250 displays an effect indicating that stimulation is being performed on the muscle part on the motion model corresponding to the body part to which electrical stimulation is applied, so that the user can easily recognize which part is being trained, The effect of training can be enhanced. In particular, if an involuntary movement is performed while simultaneously applying electrical stimulation to a plurality of parts, and the voluntary movement is further performed, it becomes difficult for the user to recognize which part of the electric stimulation is applied. Explicit display is enabled. The display control device 104 may include a directional speaker as a speaker. The directional speaker makes it easy for each user to hear the sound in his / her own exercise booth 202 without being disturbed by the sound from the adjacent exercise booth 202 even in an environment where a plurality of users exercise at the same time, such as a fitness gym. In addition, the directional speaker can easily transmit sound to not only the user but also the instructor next to the user.

  FIG. 9 schematically illustrates the arrangement of the mirror display, the attitude sensor, the display control device 104, and the user. The posture sensor 107 is installed horizontally below the display device 106 on the back side of the mirror 103, and its height is about 55 cm from the floor. The posture detection range 206 of the posture sensor 107 has, for example, an angle of view of 70 degrees in the horizontal direction and 60 degrees in the vertical direction, and is configured to detect the whole body of the user 207 standing at a position of about 2.5 m from the posture sensor 107. . Here, when the attitude sensor 107 is installed on the display device 106, detection is performed at an angle that looks down on the user 207 from above. In this case, since the incident angle on the mirror 103 increases, The posture detection through the glass may be influenced by the refraction of the glass. On the other hand, when the attitude sensor 107 is installed under the display device 106, it can be installed horizontally, so that it is difficult to be affected by refraction by the glass of the mirror 103. Further, by installing the posture sensor 107 on the back side of the mirror 103 and below the display device 106, the posture sensor 107 can be made not only conspicuous but also dust can be prevented from being fogged. The posture estimation unit 252 is a process for limiting the detection target to only the user and excluding the instructor from the detection target even when a person other than the user, for example, an instructor who advises the user of movement enters the detection range. do. Also, a mark that restricts the standing position of the instructor to a predetermined area may be drawn on the floor. As a modification, a configuration in which the height of the floor can be adjusted by moving the floor up and down may be used.

  FIG. 10 shows the appearance of the motion control device 12. This figure (a) is the appearance on the front side, and this figure (b) is the appearance on the back side. As shown in FIG. 5A, a touch panel type display unit 74 is provided at the upper part on the front side, and a dial 272 constituted by a rotary encoder is provided below the display unit 74. Each time the user operates the dial 272 to increase the level of electrical stimulation, a sound effect is produced. The display unit 74 displays a muscle model in the shape of a human body, and the user touches any muscle portion shown in the muscle model and operates the dial 272 to intuitively determine the level of electrical stimulation to the muscle. Can be adjusted. By displaying it on each of the instructor who is the practitioner and the user who is the practitioner, the environment is easy to operate. A similar image is displayed on the mirror display 105, but on the mirror display 105 side, the image is displayed in a three-dimensional manner on the image of the user reflected on the mirror 103 so that the user follows the user's body movement. Thus, the user can intuitively recognize where to train his / her body. Further, during training by electrical stimulation, it is difficult to visually grasp which part of the electrical current flows and trains, so that it can be trained more consciously by displaying on the mirror display 105. The forced stop button 273 is an emergency button that can immediately forcibly terminate electrical stimulation, that is, voltage application, when pressed by a user or an instructor in any emergency.

  As shown in FIG. 4B, an intake port 270 is provided at the lower back side of the motion control device 12, and an exhaust port 271 is provided at the upper back side of the motion control device 12. Due to the chimney effect in which the air sucked from the lower intake port 270 passes through the inside of the motion control device 12 and is discharged from the upper exhaust port 271, the heat inside the motion control device 12 is efficiently discharged naturally and exhausted. There is no need to increase the size of the fan. Since the LEDs are lit inside the plurality of holes constituting the exhaust port 271, not only the design when the back side of the motion control device 12 is reflected on the mirror 103 is improved, but the motion control device 12 is in operation. It can be visually recognized by the LED lighting state of the exhaust port 271.

  A drainage channel is provided on the liquid intrusion path in order to prevent liquid intrusion when the touch panel is operated. There is no need to waterproof more than necessary, it is easy to make and contributes to cost reduction. The motion control device 12 prevents the fall by forming a base with an iron plate that is one size larger than the bottom surface of the main body in order to suppress the fall of a thin casing having a height.

  FIG. 11 is an overhead view showing an arrangement configuration of a fitness gym. In the example of this figure, the fitness gym 200 includes six exercise booths 202. In each of the six exercise booths 202, one mirror display 105, one exercise control device 12, and one exercise space 204 are arranged. The exercise booth 202 is an area partitioned for one user, and is formed by dividing a predetermined space of the fitness gym 200 into six equal parts. The first motion booth 202a, the second motion booth 202b, and the third motion booth 202c arranged in a horizontal row on the upper side of the figure are not separated from each other by a wall or the like in the lateral direction. The fourth motion booth 202d, the fifth motion booth 202e, and the sixth motion booth 202f arranged in a horizontal row on the lower side of the figure are also not separated from each other by a wall or the like. On the other hand, the boundaries between the upper first exercise booth 202a, the second exercise booth 202b, and the third exercise booth 202c and the lower fourth exercise booth 202d, the fifth exercise booth 202e, and the sixth exercise booth 202f are: They are partitioned by a white roll screen 209 that is installed in the center in the lateral direction so as to block the field of view.

  A mirror display 105 is arranged for each exercise booth 202 along the upper and lower sides of the fitness gym 200 in the figure. The respective mirror displays 105 are arranged so as to face the central roll screen 209 and face each other with the roll screen 209 interposed therebetween, and have a counter electrode positional relationship in which the distance between them is the largest. A circular motion space 204 is arranged so that the center of the mirror display 105 is, for example, about 2.5 m. The exercise space 204 is, for example, a circle having a diameter of 1.8 m, and the user always falls within the detectable range of the posture sensor 107 as long as the user moves within the exercise space 204, and the detection of the user's posture is ensured. Near the side of the mirror display 105, the motion control device 12 is installed. The motion control device 12 is mainly operated by the instructor 208 and can also be operated by the user.

  If a person other than the user is detected by the posture sensor 107, the posture detection of the user and the image processing control are hindered. Therefore, the installation position of the instructor 208, the motion control device 12, and the adjacent exercise space 204 is set to the posture of the posture sensor 107. Set outside the detection range 206. First, the plurality of exercise booths 202 may be arranged at intervals such that the overlapping of detection angles can be suppressed between the posture sensors 107 included in each of the plurality of adjacent exercise booths 202. The setting position of the exercise space 204 for the user is clearly shown to the user by drawing a circle on the floor. The movable range of the instructor may be drawn on the floor. As a result, the detection accuracy of the attitude sensor 107 is kept high, and malfunctions are prevented. In addition to drawing a circle on the floor, the exercise space 204 may be provided with a projection on the floor surface by lighting, a mat that clearly shows the area of the exercise space 204, a cone for a mark, or the like. May be recessed or a step may be provided. The attitude sensor 107 may be provided in the exercise space 204.

  The floor is formed of a soft member, so that vibration is not easily transmitted to the mirror display 105, the posture sensor 107, and the motion control device 12, and an injury when the user falls is prevented. Making it difficult for vibration to be transmitted to the attitude sensor 107 leads to stable and highly accurate attitude detection. Further, even if the mirror display 105 falls down due to an unexpected situation, the glass of the mirror 103 is prevented from being broken. However, in the case of a specification in which the mirror 103 is fixed to the floor with an anchor, the floor material needs to be rigid enough to drive the anchor.

  In order to perform maintenance of the mirror display 105, the attitude sensor 107, the display control device 104, and the like, a passage 210 is provided behind the mirror display 105 as a maintenance space where employees in charge of maintenance can enter. Thereby, the maintainability of the mirror display 105, the display control device 104, and the attitude sensor 107 can be improved.

  As a modified example of the arrangement of the exercise booth 202, an arrangement in which a plurality of exercise booths are installed around an island type space, or a single room type in which each exercise booth 202 is separated by a partition may be used.

<Training principle>
1. Purpose The effects of electrical stimulation on muscle fatigue and metabolic responses have been reported in many studies, but there are differences in metabolic dynamics when used in combination with voluntary exercise, and when there are individual differences such as age and body composition. There are many unknown effects. Therefore, the effects of combining electrical stimulation and voluntary exercise were examined for subjects with various ages and body compositions.
2. Method The test subjects were 13 men aged 24-60 years. As an electrical stimulation application method, an electrode is placed in the proximal part of the quadriceps, hamstrings, greater gluteus, rectus abdominis, abdominal oblique, greater pectoral, latissimus dorsi, biceps, and triceps. The wear type skeletal muscle electrical stimulation device that was placed was used. The basic stimulation frequency was 20 Hz and electrical stimulation was performed for 15 minutes. The intensity of this electrical stimulation is an intensity set as high as possible within a range where the subject can voluntarily exercise. Two tests were conducted, one for receiving electrical stimulation alone and the other for performing voluntary exercise while receiving electrical stimulation. The two tests were performed randomly on different days. Before and after the test, the maximum muscle strength (MVC) and blood lactate level during isometric knee extension were measured.
3. Results FIG. 12 is a table showing the test results for 13 subjects. For example, the maximum strength of the quadriceps muscle is 85.8% (14.2% decrease) on average compared to before the test in the case of electrical stimulation (EMS) alone, and electrical stimulation + voluntary exercise (EMS + training) In the case of), a significant decrease was observed in all cases, such as an average of 82.9% (a decrease of 17.1%) compared to before the test (significance probability p value <0.05). Regarding the blood lactate level, in the case of electrical stimulation alone, from 1.4 ± 0.4 before the test to 3.2 ± 1.2 mmol / L after the test, and in the case of electrical stimulation + voluntary exercise, 1 before the test. A significant increase was observed, such as a change from .3 ± 0.4 to 4.8 ± 2.6 mmol / L after the test (the blood lactate level after the test of electrical stimulation + voluntary exercise was only for electrical stimulation) Significantly higher than the blood lactate level after the test (significance p value <0.05). In addition, a significant negative correlation was observed between the blood lactate level of electrical stimulation + voluntary exercise, body fat percentage, and subcutaneous fat thickness (abdomen). In addition, a negative trend was observed for blood lactate level, body fat percentage, and subcutaneous fat thickness (abdomen) after electrical stimulation.
4). Summary From this experiment, it was confirmed that training using voluntary exercise combined with electrical stimulation of the whole body can induce a more prominent metabolic response. Moreover, it is estimated that the effect is influenced also by individual differences, such as body composition.

In this way, the muscles are dissolved and cooled down while switching between a site where the output rate is 100% and a site where the output rate is 30% so that electrical stimulation flows from the upper body to the lower body.

  FIG. 14 is a table showing details of the configuration of the second exercise program. The second exercise program includes “WARM UP” as a preparatory exercise, “SQUAT & LAT-PULLDOWN” as the first training item, “CHEST PRESS” as the second training item, “LUNGE SIDE VENT” as the third training item, It is determined that the fourth training item “KICKBACK” and the fifth training item “PUNCH / KNEE & ELBOW / HIGH KNEEE” are executed in this order. In addition, between the first to fifth training items, “CONDITIONING”, which is a break for hydration and the like, is determined. Finally, “COOL DOWN”, which is an organizing exercise, is determined.

  “WARM UP” is set with the same frequency, time, and output rate as “WARM UP” in the first exercise program. In “SQUAT & LAT-PULLDOWN”, the same frequency, time, and output rate as “SQUAT & FLY” in the first exercise program are set. “CHEST PRESS” is a program item of 96 seconds that repeats 8 sets of electric stimulation with a frequency of 20 Hz for 4 seconds, 4 seconds for electrical suspension, and 2 seconds for electrical stimulation for 4 seconds. The output rate of each muscle to the electrical stimulation module is set to 70% for quadriceps, hamstrings, greater gluteal muscles, and oblique oblique muscles, and 100% for latissimus dorsi, great pectoral muscles, rectus abdominis, and others. 50% of the muscle.

  As described with reference to FIGS. 13 and 14, electrical stimulation is applied to the user according to the frequency, time, and output rate set for each item, and the user executes a predetermined movement as a voluntary movement under the circumstances. Moreover, not only can the upper and lower body be trained at the same time, but by applying electrical stimulation in both concentric contraction (shortening contraction) and eccentric contraction (extensible contraction), effective training is achieved in a short time. be able to. Thereby, the muscles of the whole body can be trained with a good balance.

<Attitude determination>
FIG. 15 schematically shows a posture determination screen. The display control device 104 displays the character string “X POSE” on the upper part of the screen of the display device 106, and displays the action model 212 having the shape of a human body as a pose example in the lower right corner to determine the posture to the user. Encourage a pose for. On the other hand, when the user spreads his hands and stops, the posture estimation unit 252 estimates the positions of the user's skeleton and joints based on the posture detection result by the posture sensor 107. Based on the estimated skeleton information, the display control device 104 displays the user's skeleton model 214 on the screen of the display device 106 as shown in the figure, and deforms the skeleton model 214 to follow the movement of the user's posture to be detected. . When the estimation of the position of the skeleton and the joint by the posture estimation unit 252 is completed, the posture determination ends with the display of “COMPLETE!”.

<Level adjustment>
FIG. 16 is an example of a screen for adjusting the electrical stimulation level to each body part. The screen of this figure is displayed on both the display device 106 of the mirror display 105 and the display unit 74 of the motion control device 12. As illustrated, the display control device 104 displays the muscle model 216 so as to overlap the image of the user reflected on the mirror 103. The muscle model 216 has the shape of the muscle of each body part to which electrical stimulation is applied, and displays the electrical stimulation level (voltage level) for each body part detected by the motion control device 12 as a number. The user can touch any muscle portion or number portion on the screen of the display unit 74 and turn the dial 272 to increase or decrease the electrical stimulation level for each muscle. Further, in order to confirm the electrical stimulation level with the user's own body, while applying electrical stimulation to a predetermined body part for a predetermined short time, a portion corresponding to the body part is lit on the muscle model 216. Thus, the user can adjust the electrical stimulation level for each body part while feeling it visually and bodily. As a modification, an image of the same muscle model shown in the figure may be displayed during training, and it may be displayed which body part is subjected to electrical stimulation. In that case, training that is more conscious of the part to be trained becomes possible. Furthermore, the lighting display of the muscle model may be displayed with light and darkness above and below the electrical stimulation level. In that case, the user can intuitively grasp the level of electrical stimulation.

  FIG. 17 is a diagram illustrating an example of a screen that displays an operation state using an object. On the screen of the display device 106, an operation model 212 is displayed in the lower right corner, and the operation to be performed by the user is indicated by the movement of the operation model 212. This figure is an example of a screen corresponding to an operation called “EXPANDER” for expanding and contracting both arms. When the first position state image 220a and the second position state image 220b, which are double circular objects for indicating positions corresponding to both hands of the user, are displayed in yellow and the user spreads both arms, the first position state image 220a The second position state image 220b moves so as to spread laterally following the both hands of the user, and changes to orange. At this time, the motion state image 222 which is a double rhombus object indicating the motion state is also deformed so as to expand in the lateral direction following the movement of both arms of the user. When reaching the position where both arms are fully extended, the first position state image 220a and the second position state image 220b return to yellow, and the diamond-shaped object having only the frame shape is separated from the operation state image 222 prior to the next operation. By deforming so as to contract in the lateral direction, it is guided that the next operation is contracting.

  When the user contracts both arms, the first position state image 220a and the second position state image 220b move toward the center so as to contract in accordance with both hands of the user, and change to orange. At this time, the operation state image 222 indicating the operation state is also deformed so as to contract following the movement of both arms of the user. When both arms reach the fully contracted position, the first position state image 220a and the second position state image 220b return to yellow, and the first position state image 220a and the second position state image 220b are both hands prior to the next operation. By moving to the movement target position, the next movement is guided and the movement state image 222 also moves following the first position state image 220a and the second position state image 220b. In addition, a rhombus object having only a frame shape is separated from the motion state image 222 and deformed so as to extend in the horizontal direction, thereby guiding that the next operation is an operation of extending both arms.

  As described above, when the user should spread both arms, the frame shape is separated from the motion state image 222 in advance of the user's movement and spreads in the horizontal direction, and at the timing when the user should shrink both arms. Prior to the movement, the frame shape is separated from the operation state image 222 and the movement is contracted in the horizontal direction. The first position state image 220a and the second position state image 220b also move to the target position prior to the user's movement. In this way, while guiding the user so that the direction to be performed next can be grasped visually and intuitively, the movement state is visualized following the movement of the actual user, so that the movement of the user can be visualized. Can make it easier to grasp. In other operations as well, the user's operation target and operation state are indicated by the operation model 212, the position state image 220, the operation state image 222, and the like on the same screen.
