By the way, in many sports, the quality of the competition results depends on the state of stillness before moving the body. For example, in shooting competitions that compete for how accurately the target was shot with an arrow or bullet, the use of the body at rest before the movement that shoots the arrow or bullet greatly affects the quality of the competition result. . However, the techniques disclosed in Patent Documents 1 to 4 perform evaluations while athletes and subjects are exercising, and want to train how to use the body at rest before starting the exercise. That was not enough.
The present invention has been devised under such a background, and an object of the present invention is to provide a mechanism that supports training of how to use the body at rest before starting exercise.

An exercise support apparatus according to a preferred aspect of the present invention includes a detection unit that detects a shake of one or a plurality of parts of an exerciser's body, and a notification that generates a notification sound that changes according to the shake detected by the detection unit. Sound providing means.
According to this aspect, since the notification sound changes according to the shaking of each part of the exerciser's body, it is confirmed that each part of the exerciser's body is completely stationary or is approaching complete stationary. Notification can be made through a change in the notification sound. The exerciser can learn how to use the body during the rest before starting the exercise by repeating exercises while paying attention to the change of the notification sound.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
A first embodiment of the present invention will be described. The exercise support apparatus according to the present embodiment supports archery training. In archery, the end of the arrow, called the YUDO, is hung on the bow string and picked with your fingers, pulled in the opposite direction to the target until the bow is sufficiently bent, and then released. Is fired. And if each part of the body is not completely stationary when the arrow is released, the possibility of removing the target is high.
The exercise support apparatus according to the present embodiment generates a notification sound indicating the vibration of each part of the body of an exerciser who performs archery training, and changes the notification sound based on a detection value of an acceleration sensor attached to each part. . Here, “notification sound” means a pure tone, a composite tone (a sound composed of two or more pure tones with different frequencies, or a sound other than a pure tone), a music sound, a sound, a sound effect (a wave sound or a clap sound) , A sound indicating repetition such as a water drop sound).

  FIG. 1 is a diagram illustrating a configuration of an exercise support apparatus 10 according to the first embodiment of the present invention and a mode of wearing the apparatus. The exercise support apparatus 10 includes acceleration sensors 11, 12, 13, 14, shake evaluation units 15, 16, 17, 18, a sound source 19, a notification sound synthesis unit 20, and a speaker 21. One acceleration sensor 11-14 is attached to each part of the body of the exerciser. In the example shown in FIG. 1, the acceleration sensor 11 is mounted on the right shoulder of the athlete, the acceleration sensor 12 is mounted on the top of the head, the acceleration sensor 13 is mounted on the left wrist, and the acceleration sensor 14 is mounted on the abdomen. Hereinafter, each part of the body to which the acceleration sensors 11 to 14 are attached is appropriately referred to as “attachment part”.

The acceleration sensors 11 to 14 are sensors for detecting the movement of the wearing site and its direction. It is desirable that the acceleration sensors 11 to 14 have a sufficiently small dynamic range and a sufficiently fine resolution so that even a slight movement of the wearing site can be detected. In this example, the acceleration sensors 11 to 14 are triaxial acceleration sensors, and digital signals of samples a _x , a _y , and a _{z obtained} by sampling acceleration applied to the x-axis direction, the y-axis direction, and the z-axis direction, respectively. Is output. Here, for example, when acceleration is applied from one side in the x-axis direction, the sign of the acceleration sample a _x is positive, and when acceleration is applied from the opposite side, the sign of the acceleration sample a _x is Become negative.

The shake evaluation units 15 to 18 are based on the speeds v _x , v _y , and v _z obtained by integrating the acceleration samples a _x , a _y , and a _z output from the acceleration sensors 11 to 14, and the fluctuations of those wearing parts are detected. It has a first role for calculating the period and a second role for calculating the amplitude of fluctuation based on the positions p _x , p _y and p _z obtained by further integrating the velocities v _x , v _y and v _z .
In the first role, the shake evaluation unit 15 integrates the acceleration samples a _x , a _y , and a _z of the right shoulder of the athlete, respectively, and the velocity v _x in the right shoulder direction, The velocity v _y and the velocity v _z in the z-axis direction are respectively obtained, and the absolute value | v | = √ (v _x ² + v _y ² + v _z ² ) of the right shoulder velocity is obtained. Every time the absolute value | v | of the velocity of the right shoulder falls within the range of 0 to α (α is a sufficiently small positive value) (hereinafter, this time is referred to as “speed zero” for convenience), The elapsed time from the speed zero is obtained, and the period of the latest fluctuation is set to twice this elapsed time, and a periodic signal indicating this period is output. Similarly, the shake evaluation units 16 to 18 obtain the period of each shake from the respective accelerations for the top, left wrist, and abdomen of the exerciser, and each output a periodic signal indicating the period of each shake.
In the second role, shaking evaluation unit 15 to 18, each time specifying the speed zero point by the first role, the position _p x at that _time, p y, the position of the speed zero and a preceding _{p z p} x, p 1/2 of the distance between _y and p _z is set as the latest amplitude of the fluctuation, and an amplitude signal indicating the amplitude is output. The distance is the square of the sum of the squares of the differences between the positions p _x , p _y , p _z at the preceding speed zero and the positions p _x , p _y , p _z at the subsequent speed zero. Determine by.

  The sound source 19 has a memory that stores four types of sound waveform data constituting chords. When a power source (not shown) is turned on, the sound source 19 reads out sound waveform data stored in the memory and outputs an audio signal having a waveform indicated by the sound waveform data. Such a set of four sound waveform data, for example, records a sound wave to make four copies of the sound waveform data and individually adjusts the pitch of each of the replicated sound waveform data using a pitch shifter. It is good to acquire by doing.

The notification sound synthesizer 20 mixes the filters 22, 23, 24, and 25 for performing signal processing on each of the audio signals generated by the sound source 19, the amplifiers 26, 27, 28, and 29, and the audio signal that has undergone signal processing by them. And a mixer 30 for output. The filters 22 to 25 and the amplifiers 26 to 29 are circuits for controlling the sense of distance of the notification sound to be heard by the athlete. Specifically, the filters 22 to 25 in the notification sound synthesizer 20 increase the attenuation amount of the high-frequency component of the audio signal passing through the filters 22 to 25 as the period indicated by the periodic signals output from the fluctuation evaluation units 15 to 18 increases. To do. In addition, the amplifiers 26 to 29 in the notification sound synthesizing unit 20 decrease the gain of the audio signal that passes through the amplifiers 26 to 29 as the amplitudes indicated by the amplitude signals output from the fluctuation evaluation units 15 to 18 are smaller.
The speaker 21 emits a notification sound indicated by the audio signal mixed by the mixer 30.
Among the components described above, the acceleration sensors 11 to 14 and the shake evaluation units 15 to 18 constitute “detection means for detecting the shake of one or more parts of the body of the exerciser”, and the sound source 19 and notification The sound synthesizer 20 and the speaker 21 constitute “notification sound providing means for generating a notification sound that changes according to the detected fluctuation”.

According to the above configuration, the exercise support apparatus 10 according to the present embodiment emits a notification sound from the speaker 21 that indicates the degree of shaking of each attachment site of the acceleration sensors 11 to 14. Then, the longer the fluctuation period of each wearing part, the larger the attenuation amount of the high-frequency component of the audio signal of the notification sound corresponding to them, and the smaller the fluctuation amplitude of each wearing part, the more the notification sound corresponding to them. Reduce the gain of the audio signal. Therefore, as each wearing part of the exerciser approaches the stationary state, if the period of the shaking of each wearing part becomes longer and the amplitude thereof becomes smaller, the distance of the notification sound corresponding to those wearing parts becomes longer. A sense of hearing is given to the athlete. An exerciser must rely on the sense of distance of the notification sound emitted from the speaker 21 to grasp the degree of shaking of each of his / her wearing parts, and repeat training to release an arrow when all of the notification sounds are not audible. Thus, it is possible to learn how to use the body to accurately project the target.
In addition, the notification sound corresponding to each wearing part is generated based on the sound waveform data with a pitch difference so as to form a chord, so that the exerciser can change the pitch of the notification sound generated from the speaker 21. From this, it is possible to grasp which mounting part of itself does not reach a complete stationary state.

(Second Embodiment)
A second embodiment of the present invention will be described. The exercise support apparatus according to the present embodiment supports training for cruising start of land sprint running. The crouching start is performed according to the following procedure. First, release both hands, put them on the ground, erect the knees on the front legs, and wait for the “preparation” signal with the legs on the back legs on the ground. When there is a “preparation” signal, raise the knees on the hips and hind legs, and wait for a pistol sound while standing still in that position. And at the same time as the pistol sounds, it kicks the ground and jumps forward. In this crouching start, in order to efficiently convert the force of kicking the ground to the force of moving forward, it is an ideal ideal for performing such conversion of the center of gravity of the body while waiting for the pistol sound. It is said that it is important to keep it stationary at the position.
The exercise support apparatus according to the present embodiment generates a notification sound that informs the amount of deviation between the position of the center of gravity of the exerciser who performs the training for crouching and the ideal position, and is a position that is attached to each part of the body of the exerciser The notification sound is changed based on the detection value of the sensor.

  FIG. 2 is a diagram showing a configuration of an exercise support apparatus 10A according to the second embodiment of the present invention and an aspect of wearing the apparatus. The exercise support apparatus 10 </ b> A includes a position sensor 40-k (k = 1 to 9), a gravity center fluctuation evaluation unit 51, a sound source 52, an amplifier 54, and a speaker 55. Hereinafter, the position sensors 40-k (k = 1 to 9) are collectively referred to as “position sensors 40” as appropriate. One position sensor 40 is attached to each part of the body of the exerciser. In the example shown in FIG. 2, the position sensor 40-1 is located on the left shoulder of the athlete, the position sensor 40-2 is located on the right shoulder, the position sensor 40-3 is located on the left wrist, and the position sensor 40-4 is located on the right wrist. Position sensor 40-5 is mounted on the knee, position sensor 40-6 is mounted on the right knee, position sensor 40-7 is mounted on the left ankle, position sensor 40-8 is mounted on the right ankle, and position sensor 40-9 is mounted on the buttocks. ing. Hereinafter, those parts where the position sensor 40 is attached are appropriately referred to as “attachment parts”.

The position sensor 40 is a sensor for detecting the position of the wearing part in the three-dimensional space, and is composed of, for example, an acceleration sensor and a double integrator. The position sensor 40 outputs digital signals of samples p _x , p _y , and p _{z obtained} by sampling positions in the x-axis direction, the y-axis direction, and the z-axis direction.
The center-of-gravity fluctuation evaluation unit 51 plays a role of calculating a shift amount between the center-of-gravity position and its ideal position based on the position samples p _x , p _y , and p _z output from the position sensors 40.
In this role, the center-of-gravity fluctuation evaluation unit 51 inputs the samples p _xk (k = 1 to 9) output from each of the position sensors 40-k (k = 1 to 9) to the following calculation formula (1). The position G _x of the center of gravity in the x-axis direction is obtained, and the sample p _yk (k = 1 to 9) is input to the following calculation formula (2) to obtain the position G _y of the center of gravity in the y-axis direction. The position G _z of the center of gravity in the z-axis direction is obtained by inputting p _zk (k = 1 to 9) into the following calculation formula (3). Then, the difference between the positions G _x , G _y , and G _z and the respective ideal positions set in advance is obtained and summed as the latest deviation amount, and a deviation amount signal indicating the deviation amount is output. In the following calculation formulas (1), (2), and (3), m _k (k = 1 to 9) is the left shoulder, right shoulder, left wrist, right wrist, left knee, right knee, and left ankle of the athlete , A constant corresponding to the mass of each of the right ankle and buttocks.

  The sound source 52 has a memory that stores sound waveform data of the notification sound. When a power source (not shown) is turned on, the sound source 52 reads sound waveform data stored in the memory and outputs an audio signal having a waveform indicated by the sound waveform data. The amplifier 54 decreases the gain of the audio signal generated by the sound source 52 as the deviation amount output from the center-of-gravity fluctuation evaluation unit 51 decreases. When the center of gravity of the exerciser's body is deviated from the ideal position, or when the body is close to the ideal position but is not able to stand still, the fact that the sound is emitted from the speaker 21 through the signal processing by the amplifier 54 is indicated. Will be guided. Specifically, when the position of the center of gravity of the body of the exerciser is deviated from the ideal position, a sound notification sound of a volume corresponding to the amount of deviation continues to be emitted, and unless the position of the center of gravity overlaps with the ideal position The volume does not become zero. In addition, when the center of gravity of the athlete's body is swaying, the volume of the notification sound also changes according to the change in the deviation from the ideal position, and the athlete feels as if it is a beating sound. Given to.

  According to the above configuration, the exercise support apparatus 10 </ b> A according to the present embodiment emits a notification sound for notifying the deviation amount between the center of gravity of the exerciser performing the crouching start training and the ideal position from the speaker 55. The gain of the audio signal of the notification sound is reduced as the deviation from the ideal position is reduced. Therefore, as the center of gravity of the exerciser's body approaches the ideal position and the amount of deviation between the center of gravity and the ideal position decreases, the volume of the notification sound emitted from the speaker 21 decreases. The exerciser grasps the amount of deviation between the center of gravity of the body and the ideal position and the degree of the fluctuation based on the volume of the notification sound emitted from the speaker 21 and the change thereof, and the notification sound before the pistol sounds. The ability to start crouching can be improved by repeated training in a posture that makes it impossible to hear.

(Other embodiments)
The present invention can be modified in various ways.
(1) In the first embodiment, a physical quantity detected by attaching a gyro sensor (angular velocity sensor), a position sensor, an angle sensor, or the like to each part of the body of the exerciser instead of the acceleration sensors 11 to 14 By performing a predetermined calculation, the period and amplitude of shaking of each part may be acquired.
(2) In the second embodiment, a gyro sensor (angular velocity sensor), an angle sensor, or the like is attached to each part of the body of the exerciser instead of the position sensor 40, and a predetermined calculation is performed on the physical quantity detected by these sensors. By applying, the position of the center of gravity of the body may be acquired.
(3) In the first and second embodiments, the muscle tension level, which is one of physical quantities related to the movement of the exerciser's body, is detected by the myoelectric potential sensor, and the magnitude of the tension level indicated by the myoelectric potential sensor is detected. The notification sound may be changed according to the above. Although it is difficult to visually judge the degree of muscle tension and relaxation, it is easier to achieve good performance if you start exercising from a relaxed still state without straining your muscles. Therefore, for example, when a myoelectric potential sensor is attached to the body of an exerciser, the volume of the notification sound is increased as the degree of tension indicated by the output signal of the myoelectric potential sensor is increased, and the volume of the notification sound is decreased as the degree of tension is lower. Good. According to this aspect, the exerciser can recognize that his / her muscle is in a relaxed state when the volume of the notification sound is sufficiently low.
(4) In the first embodiment, the present invention is applied to archery training, and in the second embodiment, the present invention is applied to cruising start training for short-distance running. However, sports training to which the present invention is applied is not limited to these, and is an exercise that starts from a ready posture that requires sufficient stillness, and the time from the preparation posture to the end of the exercise is approximately 30. You may apply this invention to exercise | movement which is less than a second, for example, training of the sumo wrestling and the start of a swimming race.
(5) In the first embodiment, the period and amplitude of the athlete's shake are detected based on the acceleration samples a _x , a _y , and a _z output from the acceleration sensors 11 to 14, and the longer the period of the shake, the longer the fluctuation period becomes. The attenuation amount of the high-frequency component of the notification sound was increased, and the volume was reduced as the amplitude of the fluctuation was reduced. However, one or both of the fluctuation period and amplitude may be detected based on the output signals of the acceleration sensors 11 to 14, and characteristics different from the attenuation amount and volume of the high frequency component may be changed according to the detected value. . The characteristics of the notification sound to be changed according to the fluctuation period and amplitude include the following.
a. Frequency characteristics In addition to the adjustment of the attenuation amount of the high-frequency component in the first embodiment, for example, the audio signal generated by the sound source 19 is subjected to signal processing by an equalizer, whereby the attenuation or enhancement of a specific frequency band is increased as the fluctuation period increases. There is a mode in which the degree is increased and the degree is reduced as the fluctuation period is reduced. Further, a reverberation sound is added to the audio signal generated by the sound source 19 through signal processing by an effector, and the reverberation time of the reverberation sound is lengthened as the fluctuation period is large, and the reverberation time is shortened as the fluctuation period is small. May be.
b. Pitch For example, by using the audio signal generated by the sound source 19 for signal processing such as a pitch shifter, the pitch of the notification sound is increased as the amplitude of the shake is increased, and the pitch of the notification sound is decreased as the amplitude of the shake is reduced. There are aspects.
c. Tempo (playback speed)
For example, a player that plays music data as a notification sound is mounted instead of the sound source 19, and the playback speed of music data is increased as the amplitude of fluctuation is increased, and the playback speed is decreased as the amplitude of fluctuation is reduced. There is.
(6) In the first embodiment, a plurality of notification sounds are generated based on sound waveform data with a pitch difference so as to constitute a chord. However, instead of a plurality of notification sounds having different pitches, a plurality of notification sounds having different one or more of volume, frequency characteristics, and tempo (reproduction speed) may be generated.
(7) In the first and second embodiments, the number of acceleration sensors 11 to 14 and position sensors 40 may be increased or decreased. In addition, it is not necessary to attach these sensors to the same site as in the above-described embodiment, and the site where these sensors are to be installed may be changed according to the nature of the exercise for supporting.
(8) In the first embodiment, the order of the time when the period and amplitude of the vibration of each mounting part reach a certain condition is specified, and the volume, frequency characteristic, pitch, and the volume of the notification sound corresponding to each mounting part, and Any one or more of the tempos may be changed according to the order. For example, on the condition that the period of shaking of each wearing part is longer than the threshold, specify the order in which the shaking of each wearing part satisfies the condition, and correspond to the wearing part whose order was higher The volume of the notification sound to be increased may be increased, and the volume of the notification sound corresponding to the wearing part whose order is lower may be decreased. In addition, on the condition that the amplitude of the vibration of each wearing part is smaller than the threshold value, the order in which the shaking of each wearing part satisfies the condition is specified, and it corresponds to the wearing part whose order is higher. The pitch of the notification sound to be performed may be increased, and the pitch of the notification sound corresponding to the mounting site in the lower order may be decreased. Depending on the nature of the exercise, the order of the resting parts may affect the success or failure of the competition, and these modifications are suitable for supporting that type of exercise.
(9) In the first and second embodiments, headphones may be mounted instead of the speakers 21.
(10) Same functions as the swing evaluation units 15 to 18, the center of gravity swing evaluation unit 51, the filters 22 to 25, the amplifiers 26 to 29 and 54, and the mixer 30 of the exercise support devices 10 and 10A according to the first and second embodiments. May be downloaded from a server device on the WWW (World Wide Web) to various terminals such as a personal computer, a PDA (Personal Data Assistance), and a mobile phone terminal. In this case, the sound source, the speaker, the acceleration sensor, and the like that are provided as standard in those terminals can be controlled by the downloaded program, and the same operation as that of the motion evaluation apparatus can be realized. Also, depending on the type of terminal, an acceleration sensor is not provided as standard, but in this case as well, by connecting the acceleration sensor to the interface of the terminal and detecting the shake using the output signal of the acceleration sensor It is possible to realize the same operation as that of the motion evaluation apparatus. Further, such a program may be distributed after being stored in a storage medium.
(11) In the second embodiment described above, the deviations between the position of the center of gravity of the exerciser performing the crouching start and the ideal position are represented by the position samples p _x , p _y , p output from the position sensors 40. Calculated based on _z . However, the fluctuation of the position of the center of gravity itself may be calculated, and the notification sound may be changed according to this fluctuation. For example, a set of positions G _x , G _y , G _z calculated based on the samples p _x , p _y , p _z output from the acceleration sensor 40 is stored in time series in the memory, and the latest position stored in the memory G _{x, G} y, the position previously stored and one its _{G z G x, G y,} in accordance with the magnitude of the difference between _{G z,} the notification sound volume, frequency characteristics, pitch, tempo (playback speed) It is good to change.
(12) In the said 1st Embodiment, the volume of the notification sound corresponding to them was made small, so that the amplitude of the shake of each mounting part became small. However, a sound whose sound volume changes periodically may be output as a notification sound, and the change period of the sound volume of the notification sound may be changed according to the amplitude or period of the fluctuation. For example, by preparing waveform data of a wave sound and periodically changing the volume of the wave sound, the sound that the wave is coming in is given while the wave sound is increasing, and the wave is heard while the wave sound is decreasing. It is possible to give a pulling sensation. In addition, the cycle of the change in volume is lengthened as the amplitude of fluctuation of the wearing part becomes smaller, and the volume is made constant when the amplitude of fluctuation becomes 0 (that is, an infinite cycle). Thereby, the exerciser can recognize that the wearing site is completely stationary when the volume of the wave sound has converged to a constant volume. In conjunction with this, the volume of the wave sound itself may be made smaller as the amplitude of the fluctuation becomes smaller.

It is a figure which shows the structure of the exercise assistance apparatus which is 1st Embodiment of this invention. It is a figure which shows the structure of the exercise assistance apparatus which is 2nd Embodiment of this invention.
