Description

[Technical field]

[0001] The present invention relates to a device for increasing range of motion in a joint and a method for identifying a position for utilizing the device. [Background technology]

[0002] As we age, our joints lose flexibility and our bodies become stiff, 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. In addition, there is 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, realizing supple 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 very 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.

[0003] For example, Patent Document 1 proposes a stretching aid for improving flexibility, which comprises a footboard, a heel stopper protruding from the upper side of the rear end of the footboard, and a support member which supports the footboard at a desired angle, the top surface of the footboard has a desired number of engaging grooves for angle adjustment formed in parallel in the front-to-back direction of the board at a specified interval toward the width of the board, and the support member comprises a pair of leg rods of specified length arranged parallel to each other at a distance slightly longer than the width of the board, a connecting rod which connects both leg rods fixedly together, engaging rods at the upper ends of both leg rods, positioned on a line connecting both leg rods and formed at a right angle to engage with the grooves, and a support rod located below the engaging rod and fixedly bridged horizontally between both leg rods with a distance corresponding to the thickness of the board between the engaging rod and the engaging rod.

[0004] According to the stretching aid, when 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 by the wedge action with the engaging rod, and is stably supported in an inclined state. Therefore, by standing on the footboard and using it in the same way as before, it is said to have various excellent stretching effects, such as strengthening the Achilles tendon.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-299926 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the conventional methods for increasing the range of motion of joints have problems such as using large-scale equipment and causing pain and discomfort to the muscles when stretching them, making them difficult to perform easily and continuously. In addition, if stretching is not performed for a while, flexibility returns to its original state. Thus, the 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.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an instrument that can promote muscle elongation and increase the range of motion of a joint, and a position identification method for utilizing the instrument. [Means for solving the problem]

[0008] In order to solve the above problems, the inventors discovered that pressing specific Pacinian corpuscles (specifically, those present in the palm of the hand), among the numerous Pacinian corpuscles present in the human body, promotes muscle elongation, and that this reduction can increase the range of motion of the joints, and thus completed the present invention. Effect of the Invention

[0009] According to the present invention, it is possible to provide an apparatus capable of promoting muscle elongation and increasing the range of motion of a joint, and a method for identifying a position for utilizing the apparatus. Moreover, according to the present invention, when the apparatus is used, the muscle elongation effect continues for a certain period of time (e.g., 5 minutes) even after use. Furthermore, according to the present invention, it is possible to appropriately use the apparatus. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The following description is roughly divided into the following parts.

[0012] 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 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).

[0013] (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 (A in the figure) 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) 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. (For more information on Pacinian corpuscles, see, for example, Ishiura Shoichi (editor), "Illustrated Guide to Movement and Body: Brain and Nerve Mechanisms," Mynavi Publishing, March 29, 2016, pp. 45-46; Ozawa Toji and Fukuda Koichiro (editors), "Standard Physiology," Igaku-Shoin, April 1, 2009, pp. 221-223; for the location of Pacinian corpuscles, see Johansson RS, Vallbo AB (1983) Tactile sensory coding in the glabrous skin of the human hand.

[0014] [First embodiment] (Configuration of Instrument 1) The configuration of the device 1 will be described with reference to Fig. 1 to Fig. 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 where the muscle is 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.

[0015] Fig. 1(a) is a plan view of the device 1, Fig. 1(b) is a right side view of the device 1, Fig. 1(c) is a bottom view of the device 1, Fig. 1(d) is a rear view of the device 1, and Fig. 1(e) is a front view of the device 1. Fig. 2 is an enlarged view of Fig. 1(b). Fig. 3(a) is a plan view of the device 1, and Fig. 3(b) is a left side view of the device 1. Figs. 4 and 5 are diagrams for explaining the functions of each part of the device 1.

[0016] In the following explanation, as shown in FIG. 3, the horizontal direction relative to an imaginary line connecting the two second stoppers 11B perpendicular to the Y axis is defined as the X axis, the longitudinal direction of the device 1 is defined as the Y axis, and the horizontal direction relative to an imaginary line connecting the first recess 12A and the abutment portion 21 perpendicular to the Y axis is defined as the Z axis.

[0017] The instrument 1 is designed so that when the instrument 1 is grasped by a 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 auxiliary gripping force of the ring finger. The contact portion 21 is spherical so that only the Pacinian corpuscles can be pressed with pinpoint accuracy (it is preferable that the contact portion 21 has a shape that does not stimulate (cannot be touched or is difficult to touch) anything other than the Pacinian corpuscles).

[0018] The device 1 includes a main body 10 to be 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 another 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).

[0019] The main body 10 of the device 1 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 1 within the palm of the user's hand. The first stopper 11A restricts upward movement along the Y axis.

[0020] 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 index finger and middle finger of the user when the main body 10 is held by the user to restrict rotation of the device 1 within the palm of the user. The first stopper 11A restricts downward movement of the device 1 along the Y axis.

[0021] Furthermore, the main body 10 of the device 1 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 the rotation of the device 1 in the palm of the user's hand. As shown in Fig. 3, the first stopper 11A restricts the downward movement of the device 1 along the Y axis.

[0022] As described above, the first to third stoppers 11A to 11C restrict the movement of the instrument 1 downward along the Y axis, and the position of the instrument 1 in the palm of the hand does not move in the Y axis direction when gripped. Furthermore, if the instrument 1 rotates in the palm, the contact portion 21 will be displaced from the position of the Pacinian corpuscles. In order to press the Pacinian corpuscles with the contact portion 21 by the force of the little finger, the instrument 1 must not rotate in the palm. Therefore, as shown in FIG. 4, the second stopper 11B restricts clockwise rotation, and the third stopper 11C restricts counterclockwise rotation, 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 instrument 1 is designed so that the instrument 1 comes to the intended position on the palm of the hand (the position where the contact portion 21 (Pacinian ball) of the pressing portion 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.

[0023] The main body of the instrument 1 has a first recess 12A for positioning the user's little finger at a position substantially opposite to the position where the pressing unit 20 is provided. The main body of the instrument 1 has a second recess 12B for positioning the user's ring finger adjacent to the first recess 12A. The instrument 1 of the embodiment is configured such 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.

[0024] In the embodiment of the device 1, the pressing part 20 is spherical. When the Pacinian corpuscles are pressed and stimulated, 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 part 21 (Pacinian ball) of the pressing part 20 spherical, the pressure stimulus can be concentrated only on the Pacinian corpuscles, so a predetermined range of space is formed around the contact part 21 of the ball-shaped pressing part 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), it is preferable that a space is formed around the contact portion 21 (Pacinian ball) of the pressing portion 20 of the device 1 so as not to stimulate sensory receptors other than the Pacinian corpuscles 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. In addition, the contact portion 21 of the pressing portion 20 does not necessarily have to be spherical 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.

[0025] As described above, it is preferable to pinpoint-press the Pacinian corpuscles of the palm. This point will be explained in more detail. The palm has the ulnar nerve. It is understood that in addition to the Pacinian corpuscles, other mechanoreceptors also exist on the ulnar nerve. Under these circumstances, it is preferable that the instrument according to the present invention is designed so that the pressure applied to the Pacinian corpuscles of the palm is greater than the pressure applied to the other mechanoreceptors of the palm when the instrument according to the present invention is used. From another point of view, 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 (non-contact region) where the instrument does not contact the palm is formed outside the region (contact region) where the contact portion contacts the palm so as to surround the contact region.

[0026] As described above, it is preferable that the pressing part 20 pinpoint presses the Pacinian corpuscles in the palm. The pressing part 20 can be directed to the Pacinian corpuscles in the palm during use, and the contact part 21 preferably 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 appropriately. 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 part 20 may be formed of a cylinder. When the pressing part 20 is formed of a cylinder, the bottom surface of the cylinder becomes the contact part 21, and the contact part 21 has a flat shape. The flat surface faces and contacts the Pacinian corpuscles. Furthermore, the pressing part 20 may be formed of multiple cylinders arranged concentrically with different radii. Regardless of the shape of the pressing portion 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.

[0027] (Method of holding 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 main body 10 of main body 1 by placing the little finger against second stopper 11A, the little finger in first recess 12A, and the ring finger in 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 middle finger is brought into contact with the second stopper 11B to grip the main body 10 of the main body 1 (see FIG. 7(a)). (4) The user places the base of the thumb (webbed area) against third stopper 11C and grasps main body 10 of main body 1 (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)).

[0028] As shown in FIG. 3(a), the device 1 is configured to be symmetrical about the Y axis in a plan view, but it is not necessarily required to be configured to be symmetrical about the Y axis in a plan view.

[0029] 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 a joint can be increased more effectively.

[0030] 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 and 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.

[0031] 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 to the position where the pressing unit 20 is provided, and is configured so that the Pacinian corpuscles are pressed by the pressing unit 20 when the user grasps 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.

[0032] 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 Pacinian corpuscles are pressed by the pressing part 20 by gripping 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 palm of the user's hand, so that the Pacinian corpuscles can be reliably pressed and stimulated.

[0033] 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 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.

[0034] 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, and that restricts the rotation of the device 1 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.

[0035] 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, thereby 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.

[0036] [Modifications of the embodiment] Fig. 8 is a diagram for explaining the configuration of the device 1 according to the modified embodiment. Fig. 8(a) is a diagram showing the device 1 according to the modified embodiment separated, and Fig. 8(b) is a diagram showing the device 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 device 1 were fixed to the main body part 10, but the device 1 according to the modified embodiment is configured so that the pressing part 20 and the first to third stoppers 11A to 11C are separable from the main body part 10.

[0037] As shown in Fig. 8(a), in the device 1 according to the modified embodiment, the main body 10 is configured to be separable 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 is provided with a recess 101b whose longitudinal direction is parallel to the Y-axis, and the pressing part 20 is provided with a protrusion 20a which 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 contact part 21 (Pacinian ball) of the pressing part 20 can be adjusted parallel to the Y-axis.

[0038] Moreover, the first body portion 101 is provided with a protruding portion 101a whose longitudinal direction is parallel to the Y-axis, and the second body portion 102 is provided with a recessed portion 102c which slidably engages with the protruding portion 101a of the first body portion 101. The protruding portion 101a of the first body portion 101 slidably engages with the recessed portion 102c of the second body portion 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).

[0039] Second body portion 102 is provided with protrusion 102a whose longitudinal direction is parallel to the Y-axis, and third body portion 103 is provided with recess 103b which slidably engages with protrusion 102a of second body portion 102. Then, recess 103b of third body portion 103 slidably engages with protrusion 102a of second body portion 102, so that the position of third stopper 11C (thumb stopper) can be adjusted parallel to the Y-axis.

[0040] Further, second body portion 102 is provided with convex portion 102b whose longitudinal direction is parallel to the Y-axis, and fourth body portion 104 is provided with concave portion 104b which slidably engages with convex portion 102b of second body portion 102. Then, by slidably engaging concave portion 104b of fourth body portion 104 with convex portion 102b of second body portion 102, the position of second stopper 11B (middle finger stopper) can be adjusted parallel to the Y-axis.

[0041] By configuring it in this manner, 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 differences in 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 an appropriate amount of pressure.

[0042] The function and configuration of the tool 1 according to the modified embodiment shown in Fig. 8 are the same as those of the tool 1 according to the embodiment described with reference to Figs. 1 to 7, except that 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. Therefore, a redundant description of the function and gripping method of the tool 1 according to the modified embodiment shown in Fig. 8 will be omitted (for the function and gripping method, see Figs. 4 to 7 and the corresponding descriptions).

[0043] As described later in the examples, the effect of the present invention can be achieved if the Pacinian corpuscles can be stimulated by pressing or the like. For this reason, the shape of the device does not necessarily have to be gripped with one hand like the device 1 according to the embodiment described with reference to Figs. 1 to 6, and may be, for example, a clip-shaped device provided with a pressing part that contacts the Pacinian corpuscles by pressing the Pacinian corpuscles so as to pinch the palm of the hand. Also, a pressing 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 possible to provide two pressing parts 20 in one device, corresponding to the left and right hands.

[0044] [Application] The device according to the present invention is effective for various applications involving muscle elongation, since it promotes muscle elongation. For example, specific applications include devices for improving motor function {for example, muscle elongation training (for example, stretching, yoga, muscle training); for track and field (for example, short distance, marathon, long jump), for ball games (for example, baseball, golf); for ice sports (for example, figure skating, jumping)}, and for rehabilitation (for example, lower back pain, frozen shoulder, stiff shoulder). 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 higher. 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 match, practice on the day of the match, and practice just before the match on the day of the match). 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).

[0045] 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 is stopped, flexibility is maintained to the same extent as when the device 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 is stopped, and then used again after a long time, flexibility is maintained to the same extent as before use of the device was stopped.

[0046] As mentioned above, the device according to the present invention induces muscle relaxation. Therefore, the device according to the present invention can be used in areas other than exercise and rehabilitation, such as mental care. 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. https: / / www.mext.go.jp / a_menu / shotou / clarinet / 002 / 003 / 010 / 004.htm

[0047] In addition, in order to improve symptoms of depression, social phobia, or insomnia, drugs are sometimes administered to relieve tension. For example, paragraph 0042 of Patent No. 6739846 states that "a patient (in her 30s, female) diagnosed with depression was plagued by social phobia and insomnia along with symptoms of depression, and had been prescribed intramuscular injections of Abilify (indication: depression) by a doctor at a psychiatric clinic, as well as Lexotan Tablet 2 (indication: anxiety and tension due to depression) and Brotizolam Tablet (indication: insomnia), but..." 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.

[0048] In addition, the Pacinian corpuscles are sensory receptors that detect pressure and vibration. Therefore, by vibrating the instrument, it is possible to stimulate the Pacinian corpuscles with vibrations associated with music, voice, and the like. Furthermore, it is possible to input stimuli such as the tempo, rhythm, melody, and strength of music through the Pacinian corpuscles 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 the senses of hearing and touch, and create a situation in which a person is given a sense other than the five senses (sight, hearing, smell, taste, and touch).

[0049] In addition, the Pacinian corpuscles receive vibrations of 100 to 400 Hz, and are most sensitive to vibrations of 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 the sound source include music composed only of a scale (scale frequency) of around 100 Hz to a scale of around 400 Hz, and music using a relatively large number of these scales (for example, more than half the number of scales or time). In addition, it is possible to compose new music or sound effects, or arrange (including modulation) existing music, so that the content is suitable for stimulating such Pacinian corpuscles. The term "vibration" in the present 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 by a combination of these. EXAMPLES

[0050] (Objective of this Example) In this example, a test was conducted using the grip (the device 1 described with reference to Figs. 1 to 5) on the following eight men and women of different ages (hereinafter referred to as subjects) in the following manner.

[0051] (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, 2 women in their 40s 1 woman in her 70s The attributes of the subjects measured in this study are shown in Table 1 below. [Table 1]

[0052] (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.

[0053] (Measurement method 2) The subject stood in a designated 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 (not holding anything), 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).

[0054] Specifically, the subjects were measured according to the following procedure. The subject stands along a predetermined foot position reference line and performs three types of measurement exercises. (Camera 1) Camera 1 captured images of the subject's range of joint motion during various exercises, and the data was used to confirm the expansion of the range of joint motion. (Camera 2) Camera 2 was used to capture the various exercises from the side of the subject, and it was possible to confirm from the side whether the subject's foot position was correct during exercise, as well as to confirm that the subject's body was at the correct angle during each exercise.

[0055] (Type of exercise to measure effectiveness) The exercises used to measure the effects (hereafter referred to as measurement exercises) were three types, namely, side bending, leg raising, and waist twisting, performed on both the left and right sides (see Figure 10).

[0056] (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 in a standing position with the tip of the toe aligned with the foot positioning line. The foot width was determined by dividing the vertical center line (CL) into two widths to allow each subject to easily move. 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 figure, so that the subject could return to the original position if the foot shifted during the test. The footage from Camera 1 was used to check whether the subject's standing position was correct during the movement measurement, and a decision was made as to whether the data could be used.

[0057] (b) Foot position when raising the leg (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 raised, the subject's supporting foot was set so that it was attached to the shoe to be raised, and the heel was positioned along the frame indicated by line L. The subjects checked their foot position each time they performed the leg-raising exercise. Whether the subject's foot position was correct during the movement measurement was confirmed by looking at the image from Camera 2, and a decision was made as to whether the data could be used.

[0058] (Measurement Procedure) (a) Subjects were asked to gather individually at set times. (b) The purpose of the measurements, the purpose of use of the data, safety management, and any 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.

[0059] (Detection of the location of Pacinian corpuscles in the palm) As mentioned above, the Pacinian corpuscles in the palm are one of the mechanical receptors found in the skin, and as illustrated in Figure 1, they are located on the tip of the middle finger and in the palm below the little finger, and are pressure-detecting joints.

[0060] (Detection of the position of the Pacinian corpuscle in the middle finger: see Figure 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 pad side of the tip of the middle finger (first joint) was pressed slowly and quickly with an acupressure stick to detect the area of ​​sharp pain. (c) Next, the area of ​​pain (Pacinian point) was marked with a marker.

[0061] (Detection of the location of the Pacinian corpuscles in the palm: see Figure 13(b)) In the measurements of this example, Pacinian corpuscles were detected in the palm of the hand that was pressed. (a) The subject was asked to stimulate the palm of his / her hand using a pressure point pressing stick at different locations and feel the difference in stimulation when pressed with the pressure point pressing stick. (b) Next, the center of the palm on the little finger side was pressed slowly and quickly with the acupressure stick to detect the spot where a sharp pain similar to that felt with the middle finger was felt. (c) Next, the area of ​​pain (Pacinian 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.

[0062] Figure 14 shows images showing the positions of the Pacinian corpuscles detected on the palm of each subject. Note that the marks made with a magic marker are difficult to see in the image of Figure 14, so they have been circled.

[0063] (measurement) (a) At the point where the angle of each movement was maximum, cameras 1 and 2 were operated simultaneously using two remote controls to take pictures 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 deviations in the body position (especially the position of the feet). The experimenter also made sure that the grip was properly placed on the Pacinian corpuscles and ensured that the grip was held in the designated position. (c) There was a three-minute interval between each of the three types of exercise, and the subjects completed each exercise. It should be noted that, after each exercise, it was confirmed that the pressing portion 20 of the device 1 was reliably contacting (pressing) the location of the Pacinian corpuscles on the palm of the subject's hand.

[0064] (Provision of the origin) The origin of the subject's body (the origin for measuring the effect of increasing joint range of motion) 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, and the rightward direction is positive and the leftward direction is negative.

[0065] (Grid origin) In addition, 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.

[0066] (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 leg lift right · Left leg lift origin Origin of lateral bending left and right

[0067] 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 thought to be the femoral joint (see Figure 15(a)). (b) The point where the line L2 passing through the center of the foot intersects with the line L1 is set as the origin of the left leg (see Figure 15(b)). (c) The position symmetrical about the vertical axis center line CL of the origin of the left leg-raised body is 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 the origin of the lateral bending body (see Figure 15(c)).

[0068] Next, the procedure for obtaining the measurement results will be described. The measurements for each movement were compared with respect to the origin of the body (see Figure 16). (a) From the measured images, 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 pastes all the pasted images at the center of the PPT screen at the same scale. Therefore, the grid origin of each image is in the same position on the PPT screen, allowing accurate comparison.

[0069] How to compare the dimensions of the manual and gripping grips (see Figure 17) (a) The image pasted on the PowerPoint 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) Measurement results were converted to actual size at the following magnifications: When a box with a 600mm square was measured on a 65-inch screen, it was 167mm. From this, the measurement magnification of the screen was calculated as 600 / 167 = 3.593 times.

[0070] Results of lateral bending (data was compiled in the same manner for leg raising and waist twisting) (see Figure 18) (a) Identify the body origin mentioned above (in Figure 18, the body origin for lateral bending). (b) Place a point with a pencil at the center of the elbow joint on the tracing paper. On the computer's PowerPoint, place a point on the right angle of the white triangle to match that point. (c) Draw a straight line (vertical center line) from the origin of the body in lateral bending to the point. (d) The angle of trunk flexion away 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, determine the joint movement angle from the origin when gripping (see Figure 19).

[0071] (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 on top of the image of the bare hand. All images of the human body only pasted in the PPT are extracted to the same scale and origin. Therefore, even if the image of the gripping hand is pasted onto the image of the bare hand, the exact origin and scale are maintained, resulting in an accurate comparison (see Figure 20). The comparison between the bare hand and the stick grip was also performed using the same procedure.

[0072] (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 are compared. Note that Figure 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).

[0073] (legs up) 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).

[0074] (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 toward the vertical axis center line from the state of being stretched straight down, twisting the body using only the upper body. In this example, the twisting angle (θ1) when using the hand, the twisting angle (θ2) when using the rod grip, and the twisting angle (θ3) when using the grip grip were measured with the intersection of the perpendicular line of the vertical axis center line and the twisting angle line as the center, and the differences were compared. Note that Figure 23 shows images of the twisting angle (θ1) when using the hand (dotted line) and the twisting angle (θ3) when using the grip grip (dotted line).

[0075] (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. In addition to measurement images of the "stick" and "grip (instrument 1)", Fig. 24 to Fig. 26 also show measurement images of the manual hand.

[0076] (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 understood that the range of motion of the joint is expanded. Note that only subject 7's right waist twist has a negative value of θ3, but this is a slight difference and does not affect the results of this measurement, so it can be said that the effect of the grip (instrument 1) of the present invention is clear.

[0077] (Comparison between stick and tool (grip)) FIG. 28 is a diagram showing the measurement results and the difference (Δθ2) of the angle (θ2) when holding the “stick” and the angle (θ3) when holding the “grip (instrument 1)” measured as described above. As shown in Figure 28, although there were differences in 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 increased. In addition, when gripping a stick, the range of motion of the joints is slightly greater than when using bare hands, but the difference in the effect of increasing the range of motion of the joints when gripping a grip (Equipment 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 the recording of the right leg lift was not done well. For the other subjects, the recording and measurement were done well, and the effect was also remarkable. Therefore, 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.

[0078] (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 when gripping the grip (Apparatus 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 subject 6's right leg lift, he was the first subject and we were unable to photograph him, so measurements could not be taken.

[0079] (Consideration) 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.

[0080] Furthermore, other measurements (not shown) made by the inventors showed that the muscle relaxant effect was cross-sectional between the left and right sides. For example, when the device was held in the right hand, muscle relaxation was more pronounced in the muscles on the left side of the body. In contrast, when the device was held in the left hand, muscle relaxation was more pronounced in the muscles on the right side of the body.

[0081] Taking the side bending exercises shown in Figures 24(a) and (b) as an example, when holding the tool in the right hand and performing left side bending (using Figure 24(a)), the flexibility of the body was increased compared to when holding the tool in the left hand and performing the same left side bending. Conversely, when holding the tool in the left hand and performing right side bending (using Figure 24(b)), the flexibility of the body was increased compared to when holding the tool in the right hand and performing the same right side bending.

[0082] [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 it has a ring (finger locking part) that locks onto the user's finger.

[0083] (Configuration of the device 200) The configuration of an 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. Like the above-described instrument 1, the instrument 200 according to the second embodiment is designed to apply pressure stimulation to accurate positions of the Pacinian corpuscles to increase the range of motion of the joints.

[0084] The device 200 includes a main body 210 to be held by a user, a pressing portion 220 protruding from the main body 210, and a ring portion 230 into which the user inserts his or her little finger and ring finger. In Fig. 31 and Fig. 32, the main body 210 has a rectangular parallelepiped shape with chamfered corners.

[0085] 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 adopted for fixing the ring portion 230 to the main body portion 210. For example, it is conceivable to press-fit the ring portion 230 to the main body portion 210, fix it using a general screw (fixing screw), or fix it by adopting an engaging claw structure.

[0086] 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, and these pinky ring 231 and ring finger ring 232 will be described later. It is also possible to integrally mold (synthetic resin mold) 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.

[0087] 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 adopted for fixing the pressing part 220. For example, the shaft part 222 may be press-fitted into the main body part 210, may be fixed using a general screw (fixing screw), or may be fixed by adopting 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).

[0088] The shape of the main body 210 is not limited to a rectangular parallelepiped. Various shapes of the main body 210 can be adopted in consideration of ease of gripping, improved functionality, and the like. For example, the main body 210 may be appropriately provided with projections and recesses in consideration of 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 types, katakana type, hiragana type, etc.), or symbol-shaped in consideration of design.

[0089] 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.

[0090] Here, the contact portion 221 has a shape that allows pinpoint pressure on only the Pacinian corpuscles (in this embodiment, it is ball-shaped, but it is sufficient to be able to pinpoint pressure on only the Pacinian corpuscles, and other shapes are not precluded) (it is preferable that the shape does not stimulate (cannot be touched or is difficult to touch) anything other than the Pacinian corpuscles). This point will be described later as a modified example (Figs. 59 and 60).

[0091] The shaft portion 222 connects the main body portion 210 and the contact portion 221. The shaft portion 222 also has a function of separating the main body portion 210 and the contact portion 221 from the palm of the user when the main body portion 210 is held by the user.

[0092] In the following description, as shown in Figures 31 and 32, the direction in which pressing portion 220 protrudes relative to main body portion 210 is defined as the Z-axis direction, the direction in which ring portion 230 protrudes relative to main body portion 210 is defined as the X-axis direction, and the direction perpendicular to these X-axis and Z-axis directions is defined as the Y-axis direction.

[0093] As described above, two rings, the little finger ring 231 and the ring finger ring 232, are formed side by side on the ring unit 230. The user inserts the little finger into the little finger ring 231 and the ring finger into the ring finger ring 232, and wraps the main body unit 210 around the inside of the palm with the pressing unit 220 facing the palm (FIG. 33).

[0094] The positional relationship of each part of the device 200 is designed so that, when the user grips the device 200, the abutment part 221 at the tip of the pressing part 220 comes to a position where the Pacinian corpuscles are in contact with the device 200. 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 press the Pacinian corpuscles with the abutment surface 221a of the abutment part 221, stimulating them.

[0095] 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 instrument 200 is used, it is preferable that a space is formed around the contact portion 221, as with the instrument 1 of the first embodiment. In other words, it is preferable that a region where the instrument 200 does not contact the palm (non-contact region) is formed outside the region where the contact portion 221 contacts the palm (contact region) so as to surround the contact region.

[0096] Such a ring model instrument (instrument 200 in this example) can also be described as follows: The most difficult aspect (or one of the most difficult aspects) of an instrument capable of pressing 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 or slippage.

[0097] 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 force of pressure or the movement of the fingers.

[0098] In the device 1 of the first embodiment 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.

[0099] In contrast, in the device 200 of the second embodiment, the main body portion 210 (grip) is positioned in the palm of the hand by three points: the little finger ring 231 attached to the main body portion 210, the little finger pressing portion (the portion of the main body portion 210 that is pressed by the little finger), and the abutment portion 221 (Pacinian ball) of the pressing portion 220, so that the abutment portion 221 is accurately fixed to the position of the Pacinian corpuscles.

[0100] Fig. 33 shows a state where the ring model instrument 200 is held in the left hand. However, the instrument 200 shown in Fig. 33 is a schematic illustration of a prototype of the instrument 200 shown in Figs. 31 and 32 to facilitate illustrating the positional relationship. Therefore, although the shape does not match that of the instrument 200 shown in Figs. 31 and 32, it has portions corresponding to the main body portion 210 and the ring portion 230. In Fig. 33, these portions are denoted by the reference numerals 210 and 230.

[0101] The position 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, a ring part (little finger ring 231) is provided in a position of main body part 210 facing the base of the little finger (the third joint), thereby realizing the following functions.

[0102] That is, 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).

[0103] In addition, the angle θ (θ°) between the ring part 230 and the main body part 210 is fixed, the part pressed by the little finger (point B, indicated by a triangular mark) and the pressing part 220 are aligned on the arc (D) formed by the little finger and the palm, and the pressing force of the little finger acts accurately 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.

[0104] The pressure force (pressing force, shown by arrow F) on the Pacinian corpuscles is generated by the little finger and ring finger (mainly the little finger). When the main body portion 210, whose position is restricted by the ring portion 230, is pressed mainly by the force of the little finger, the pressing portion 220 (tip at point C) is pushed into the palm by the axial force. In addition, a frictional force is generated between the main body portion 210 and the palm by the force of the little finger etc. pressing almost directly from above. Then, the force from almost directly above and the restriction by the ring portion 230 combine to suppress the left and right rotation of the instrument 200 (left and right rotation, which is a displacement around the Z axis), as shown in FIG. 33.

[0105] Therefore, when the user grasps the main body 210, the instrument 200 is affected by the pressure of the little finger and the 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 with the instrument 1 of the first embodiment, it becomes easier to perform accurate pressing of the Pacinian corpuscles.

[0106] In order to fix the main body part 210, it is sufficient that the first joint on the tip side of the little finger is in contact with the main body part 210 at point B. It is desirable to determine the shape and dimensions (size) of the main body part 210 and the relationship with the little finger so that a gap (gap 882 in the referenced FIG. 52) can be secured between the little finger and the main body part 210 at points other than point B. By floating the little finger (the portion from point B to the base side) above the main body part 210, a space for moving the little finger can be secured, and the force applied from the little finger to the main body part 210 can be easily adjusted.

[0107] (Effect when using the device 200) According to the ring model instrument 200 as described above, the range of motion of the joint can be expanded to the same extent as the instrument 1 of the first embodiment (illustrated in Figs. 1 and 8). Fig. 57 shows the results of an experiment on the effect of expanding the range of motion of the joint by the instrument 200. For comparison, a type without a ring portion (called the "Nike model"), as shown in a different orientation in Figs. 68(a) and (b), was used. This type has the basic functions of the instrument 1 of the first embodiment shown in Figs. 1 and 8, and has a main body portion 10 and a pressing portion 20 like the instrument 1.

[0108] 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 if there is no difference in the pressing force of the pressing parts (20, 220) (see Figure 57). Figure 57 shows, from top to bottom, photographic images of lateral bending in the case of bare hands (not holding anything), when using the Nike model, and when using the ring model.

[0109] According to Figure 57, in the case of bare hands (upper image), the subject's right arm stops at a position higher than horizontal. In contrast, when the Nike model (middle image) and the Ring model (lower image) are used, the subject's right arm reaches a position lower than horizontal to the same extent.

[0110] As mentioned above, with regard to misalignment in the rotational direction, by providing the ring portion 230, rotation around the Z axis (left and right rotation) can be prevented, making it easier to accurately press the Pacinian corpuscles than with the instrument 1 of the first embodiment.

[0111] [Application] As long as no trouble 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.). In addition, the uses of the ring model tool 200 can be explained as follows.

[0112] For example, when an athlete or professional athlete is performing serious exercise, it is considered that it is more suitable 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 and exercising, the device 1 falls and is likely to be damaged. However, in the ring model device 200, the fingers are passed through the ring portion 230 and are engaged with the ring portion 230, so the device 200 does not fall even if the palm of the hand is opened. In other words, the ring model does not easily fall from the palm of the hand even if the hand is opened, because there is a ring on the little finger (little finger ring 231).

[0113] Furthermore, 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 effect on movement is kept to a minimum.

[0114] Furthermore, the ring model tool 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 ordinary person performs daily exercises, walking, jogging, hiking, etc., the effect (grip effect) of the tool 200 causes muscle relaxation of the entire body, making it easier to obtain a sense of an expanded range of motion in the joints on a daily basis. Furthermore, compared to performing these actions without gripping the tool 200, the effect of lifting the legs is obtained more comfortably, and it becomes possible to feel a sense of lightness in the entire body more regularly.

[0115] 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. In addition, the size of the hand and the Pacinian point of children change almost every year as they grow. For this reason, the most effective results can be achieved by creating a device (personal grip) that is shaped and sized to fit the palm of the person's hand according to individual differences or according to age and generation.

[0116] [Invention of a method for identifying Pacinian 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.

[0117] (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. By creating a device (personal grip) with a shape and size that fits the palm of the person's hand according to individual differences or according to age and generation, it becomes easier to achieve the effects of the device 1 or device 200.

[0118] Furthermore, the Pacinian corpuscles in the palm of the hand are sensory receptors with a size of about 1 mm, which are found only in one place on the palm. It has been found that the range of movement of the mouth 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 about 0.7 mm in diameter. Tadashi Oyama et al., "New Edition: Handbook of Sensory and Perceptual Psychology", 1994 / 1 / 20, P.1180-p.1181

[0119] [A comparison test of the range of motion of joints 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 in the first embodiment of the device 1 (FIG. 13(b)).

[0120] Figure 34(a) shows the image of the palm of the subject taken at that time. A mark was made on the palm with a marker (felt-tip pen; the "marker" described so far also refers to a felt-tip pen). The position of the mark is called point P.

[0121] Next, points at a specified distance (3 mm in this case) up, down, left and right from point P were designated in order at 90-degree angles clockwise 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, to measure the expansion of the range of motion of the joint by lateral bending.

[0122] [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 closest to the subject's head) show the state of lateral bending when point P and points A to D are pressed.

[0123] A horizontal line is added to these images based on the position of the subject's elbow joint in the image marked with the symbol "P" (the image at the left end of Figure 34(b)). When the image of point P on the left end is compared with the images of points A to D marked with the symbols "A" to "D," it is found that when point P is pressed, the subject's elbow joint reaches below the horizontal line.

[0124] It can be seen that when point P is pressed, the elbow joint of the subject reaches a lower position than when points A to D are pressed. In addition, when points A to D are pressed, the flexibility is only exerted to the same degree. 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 instrument.

[0125] [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.

[0126] 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 due to stimulation of the Pacinian corpuscles can be adopted. 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 adopted as the human body reaction.

[0127] 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 column of page 11 of this paper (lines 7 to 11) states, "The Pacinian corpuscles of the touch receptors generate an action potential at their endings depending on the intensity of pressure or vibration stimuli, and as the stimulus increases, the action potential increases, generating an action potential in the sensory nerve which is transmitted to the central nervous system and recognized as a sensation."

[0128] Other examples include the following: Maki, Makoto; Kishigami, Hirotoshi; Yamaguchi, Natsuko; Wada, Tatsuhiko; Ueno, Takeharu (1995) "Preparation of electrodes for microsurface electromyography of finger muscles and its basic study", https: / / eprints.lib.hokudai.ac.jp / dspace / bitstream / 2115 / 37580 / 1 / 8_137-142.pdf Masuda Tadashi (2015) "Special Feature 3: Measurement Methods for Ergonomics Part 4: Measurement and Analysis of Bioelectrical Phenomena and Others (1) 1 -Measuring Methods for Surface Electromyograms and Their Applications to Ergonomics-" https: / / www.jstage.jst.gojp / article / jje / 51 / 6 / 51_400 / _pdf / -char / ja *The "3" in "Feature 3" is a circled number.

[0129] Action potentials can be measured using an action potential measuring device (also called an "action potential measuring device," "action potential measuring means," "human body reaction measuring device," "human body reaction measuring device," or "human body reaction measuring means"). Previous investigations by the inventors (for example, various investigations such as the investigation in the experiment described using FIG. 14) have revealed that the Pacinian point on the palm of the hand is located within a 2 cm square area for all people. This 2 cm square area will be referred to as the "distribution area" below. FIG. 35 shows that point P of a certain subject is located almost in the center of the distribution area shown enclosed in a square frame.

[0130] 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.

[0131] 36 and 37 are schematic diagrams showing the configuration of a Pacinian point identifying system (identifying system) 600 according to this embodiment. In this identifying system 600, a point identifying device 601 is used. In the point identifying 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.

[0132] 37, a Z-axis displacement mechanism 610 is provided on the Y-axis stage 608, and a pressing rod (pressing body) 612 is held in the Z-axis displacement mechanism 610. The pressing 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 a direction perpendicular to a plane (similar to the flat surface of the base plate 602) formed by the X-axis and Y-axis. Here, the X-axis, Y-axis, and Z-axis of the identification system of this embodiment are defined for the point identification device 601.

[0133] 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 for engaging the subject's arm 614.

[0134] 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 an input waveform can be used. Also, instead of the electrode sheets 618, electrodes having needles (needle electrodes) can be used.

[0135] The X-axis stage 606, the Y-axis stage 608, and the Z-axis displacement mechanism 610 may be automatically controlled via a controller (not shown), or may be manually displaced by a measurer (operator). Alternatively, automatic and manual mechanisms may be used in combination, for example, the X-axis stage 606 and the Y-axis stage 608 may be automatically controlled, and the Z-axis displacement mechanism 610 may have a manually displaced pressing rod 612.

[0136] In identifying the Pacinian point, first, the subject places his / her arm 614 with the palm facing up on the surface plate 602. The subject places the part of the arm 614 on the little finger side against the stopper 616 and positions the palm below the linear guide 604.

[0137] The measurer moves the linear guide 604 to move the pressure rod 612 within the XY plane, guiding it to the vicinity of the aforementioned distribution area (a 2 cm square area in FIG. 35) of the palm under the little finger. The measurer moves the pressure rod 612 arbitrarily within the XY plane so as not to go too far outside the distribution area. Furthermore, the measurer stops the pressure rod 612 at a position arbitrarily, and lowers the pressure rod 612 at the point where it was stopped.

[0138] When the lowered pressure rod 612 hits the palm and presses 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 areas and observes the waveform at each destination.

[0139] The point where the waveform is most clearly seen is determined to be the Pacinian point, and a mark is made at that position. This mark may be a sticker attached by the measurer, or may be ink drawn with a pen tip attached to the tip (here, the lower end) of the pressing rod 612.

[0140] 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 identifying device 1. For example, if the performance of the linear guide 604 is such that the pressing rod 612 can be moved in increments of 0.1 mm, the Pacinian points can be identified in increments of 0.1 mm. Then, by using the instrument 200 with the identified positions as a marker, it becomes possible to appropriately use the instruments (instrument 1, instrument 200, etc.).

[0141] In this embodiment, the identifying system 600 is provided with a linear guide 604 to identify the Pacinian points, but the present invention 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 pressing rod 612 held in the hand against the palm one by one within the distribution area (FIG. 38) and checking the change in the action potential with the action potential measuring device 620 (referring to FIG. 36).

[0142] In addition, according to the identification system 600, since it is possible to identify the Pacinian points based on the change in the action potential measuring device 620, it is possible to find the Pacinian points more objectively than when not using the identification system 600. In addition, it is possible to find the Pacinian points scientifically without relying on the skill of the measurer or the sense of the subject.

[0143] Therefore, it becomes possible to set up dealers, sales agents, exhibition halls, showrooms, antenna shops, and handling stations (hereinafter referred to as "dealers, etc.") of the appliances (apparatus 1, appliance 200, etc.) in a wide area in Japan 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 a manager of each store) at each dealer clearly identifies the pachinni point of each customer and then sells the appliances (apparatus 1, appliance 200, etc.). This makes it possible to make the most effective use of the appliances (apparatus 1, appliance 200, etc.).

[0144] In addition, according to the identification system 600, it is possible to find the Pacinian points objectively as described above. Therefore, it is not necessary to provide employees of stores, etc. with advanced education or guidance that requires a lot of time in order to be able to find the Pacinian points.

[0145] Furthermore, the specific system 600 may be installed and used at the home of a user of the device (such as the device 1 or the device 200). In this case, for example, it becomes possible for the user to identify the Pacinian point every morning before using the device (such as the device 1 or the device 200) and always accurately stimulate the Pacinian point.

[0146] (Creating a support jig) It is also possible to create an auxiliary tool (also called a "support tool," "2D support tool," "2D tool," or "template") that identifies and records the Pacinian points for each user, and use this auxiliary tool as a positioning format (positioning format) to make it possible to always easily reproduce the Pacinian points. The auxiliary tool (support tool) was considered for the following reasons:

[0147] That is, when 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, the user of the device (device 1, device 200, etc.) needs to know his / her Pacinian points immediately before each use of the device. Also, when the user installs the identification system 600 at home as described above, problems of cost and installation space are likely to arise. Therefore, a technology is needed that allows the user to easily identify the Pacinian points.

[0148] Therefore, at a store or the like, the identification system 600 finds the exact Pacinian point, marks the Pacinian point on the spot with a marker or the like, and takes a photograph of the palm of the hand with a camera. The camera used here may be a dedicated camera such as a digital camera, or a camera provided in a smartphone, a mobile phone, a tablet terminal, a notebook PC, an e-book reader, a wearable computer, or a portable game machine. The camera may be a camera owned by the user. Furthermore, the photographing may be performed by the user using his / her own camera, or may be performed by a camera provided at a store or the like.

[0149] Next, based on the image data of the photographed palm, the photographed 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). Figure 39(a) shows a schematic diagram of a transparent plate 622 on which an image of the palm has been printed. Note that the image of the palm may be printed semi-transparent. In addition, the printing machine used at this time may be any of a variety of general types, as long as it is capable of printing on transparent plates.

[0150] After that, for example, a circular hole 624 is made at the Patini 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 a marker to pass through, as shown in Fig. 39(b) described later.

[0151] 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 the palm matches the image of the palm. Fig. 39(b) shows a schematic diagram 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 to the side on which the palm is placed, and makes a mark on the palm.

[0152] In the example of Figures 39(a) and (b), a guide tube 628 that guides a writing implement 626 to prevent the writing implement 626 from tilting is provided on a transparent plate 622. Also, a standing wall portion 630 that forms a space for placing the palm and allows the palm to be inserted is formed on the transparent plate 622. Furthermore, reference numeral 632 in Figure 39(b) denotes a printed layer with an image of a palm.

[0153] In this way, the transparent plate 622 is produced as an auxiliary tool (support jig) and the transparent plate 622 is used to mark the palm, thereby making it possible to indicate the exact positions of the Pacinian points on the palm. Then, by placing the contact portion (such as 21 or 221) of the tool (such as the tool 1 or the tool 200) on the marked Pacinian points, the Pacinian corpuscles can be accurately pressed.

[0154] That is, the Pacinian points accurately measured by the specific system 600 are marked, a photograph of the palm is taken, and a transparent plate 622 is made with a copy of the palm image in 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 the transparent plate 622 is handed over to the user.

[0155] 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. Then, the user can 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.

[0156] The user of the equipment needs to know the exact location of the Pacinian point when starting exercise with the equipment (grip exercise). In other words, it is most effective to press the Pacinian point accurately when exercising or walking with the equipment.

[0157] For this purpose, it is necessary to mark one's own Pacinian point immediately before starting exercise, etc., and grasp the device while being aware of accurately placing the pressing part (pressing part 20, 220, etc.) on the Pacinian point. It is also desirable for the user to mark the exact position of the Pacinian point on his / her hand every 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 the appropriate use of the device. It is also possible to promote daily use of the device, such as every day, in the morning and evening.

[0158] (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 identifying Pacinian points, a large number of collected data (sample data) of Pacinian points are processed using AI (artificial intelligence) (Fig. 45, Fig. 46), and the optimal Pacinian points are selected to create an auxiliary tool (support jig) (Fig. 46).

[0159] 45 and 46 are schematic diagrams showing the configuration of an identification system 700 according to this embodiment and an identification method executed by the identification system 700. In FIG. 46, the name "Pacini point detection and printing system" is given, and this name refers to the identification system 700 according to this embodiment.

[0160] In the identification system 700 (and the identification method) shown in Figures 45 and 46, first, a predetermined number of men and women (for example, about 100 men and women in total, about 200 men and women) are selected as sample collection subjects. Then, as shown in the bottom part 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.

[0161] Here, Figures 45 and 46 show each step of the identifying method using a partial configuration of identifying system 700. S710 in Figure 45 means a step of the identifying method executed in identifying system 700. Other symbols with "S" such as "S720" and "S730" also mean each step of the identifying method.

[0162] 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 an example of 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). More accurate identification can be achieved by having a skilled worker identify the Pacinian points.

[0163] Next, the hands of each person with the Pacinian points marked are photographed (S720). Fig. 41 shows only a portion of the samples (six people) as an example. To photograph each person'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.

[0164] 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 Pacinian point with the camera 710, the hand of an 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 arranged above the base plate 704.

[0165] When the hand is placed on the base 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 so that the entire palm is included. The entire palm is then photographed by the camera 710, and image data of the palm including the Pacinian point is acquired.

[0166] Palm images are taken for all sample collection subjects (S730). The attribute data of the sample collection subjects (such as gender and age) and data obtained from the palm images are then compiled into a database and used as big data for AI-based Pacinian point detection.

[0167] For the Pacinian point exploration, AI learning (AI learning) is performed in advance (S740). For the AI ​​learning, for example, data on the feature points of each individual's hand linked to the attribute data of the sample collection subject (learning feature point data) is collected. 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.

[0168] Furthermore, 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, etc.). Furthermore, examples of measuring these items include, for example, recognizing the wrinkles and joints of the wrist through image processing, determining a part of these (such as the center) as a reference point, and measuring the distance from the reference point to the fingertip or joint.

[0169] 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 be a computer in which multiple computers are connected via a communication network. Furthermore, the processing device may be a computer connected between a computer installed at the location where the Pacinian points are identified and a computer (such as a server device) in a remote location.

[0170] 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 the position data of the Pacinian points is used as training data. For example, 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).

[0171] There are various possible applications for the training feature data. For example, we quantitatively analyze the correlation between items such as the length from the wrist to the tip of each finger, the length of each joint of each finger, etc., and create a function for regression analysis from the relationship between the analysis results and the position data of the corresponding Pacinian points.

[0172] In addition, the AI ​​learning method is not limited to the above-mentioned machine learning with teacher learning, but can also adopt other machine learning methods such as unsupervised learning and reinforcement learning. In addition, the analysis method in machine learning is not limited to regression analysis, but can also adopt 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 a coordinate that specifies a single position, clustering or other analysis methods can also be adopted as an analysis method. In addition, the AI ​​learning method is not limited to statistical machine learning, but can also adopt deep learning.

[0173] To perform such 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 determined. 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.

[0174] When the results of the AI ​​learning are used to search for the Pacinian points, as shown in the lower left of FIG. 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 having 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 it is. Here, an example is explained in which the point photographing device 702 is used as the palm photographing device.

[0175] When photographing the palm, the position of the hand is fixed by placing the palm against hand side stopper 706 and little finger stopper 708. The photographing range of camera 710 is adjusted to include the entire palm. Then, the entire palm is photographed by camera 710, and image data of the palm is acquired.

[0176] Data on the characteristics of the user's hand (user feature data) is extracted from the acquired palm image data (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.

[0177] Next, a calculation is performed to calculate the location of the Pacinian points based on the results of the AI ​​learning using the user's attribute data (e.g., data such as gender and age) and user feature data (S742).Then, the location of the user's Pacinian points is identified (discovered) by estimation, and data on the identified Pacinian points (Pacinian point location data) is stored (S750).

[0178] After that, a mark is placed on the palm of the user's hand based on the Pacinian point position data identified by the AI, and the palm is photographed (S760). In placing the mark on the palm, for example, a point printing device 711 equipped with a photographing function, as exemplified in Figures 43(a) and (b), can be used.

[0179] 43(a) and (b), a linear guide 714 is provided on a base plate 712 having a flat surface, similar to the point identifying device 601 (FIGS. 36 and 37) in the identifying system 600 described above. The linear guide 714 includes 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.

[0180] As shown in Fig. 43(b), the Y-axis stage 718 is provided with a Z-axis displacement mechanism 720, which holds a print bar 722. A typical writing implement such as a ballpoint pen or felt pen can be used as the print bar 722. The print bar 722 can be displaced in the Z-axis direction via an elastic body (such as a coil spring or a leaf spring) 723.

[0181] Here, the Z-axis direction is a direction perpendicular to a plane formed by the X-axis and the Y-axis (similar to the flat surface of the surface plate 712). Moreover, the X-axis, the Y-axis, and the Z-axis according to this embodiment are set in the same directions as the respective axes in the identification system 600 of the above-mentioned embodiment.

[0182] As shown in Fig. 43(b), a camera 724 capable of photographing the downward direction is provided on the Y-axis stage 718. As the camera 724, a camera similar to the camera 710 of the point photographing device 702 shown in Figs. 42(a) and (b) can be used.

[0183] Furthermore, the X-axis stage 716, the Y-axis stage 718, and the Z-axis displacement mechanism 720 may be automatically controlled via a controller (not shown), or may be manually displaced by a measurer (operator). Alternatively, automatic and manual mechanisms may be used in combination, for example, the X-axis stage 716 and the Y-axis stage 718 may be automatically controlled, and the Z-axis displacement mechanism 610 may be configured so that the print bar 722 is manually displaced.

[0184] 43(a), the arm (here, the right arm) 426 of the person to be marked can be placed on the base plate 712. A hand side stopper 728 and a little finger stopper 730 are provided on the base plate 712 so as to protrude upward. The arm 726 of the person to be marked is then positioned with the side surface 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.

[0185] Based on the Pacinian point position data identified by the AI, the X-axis stage 716 and the Y-axis stage 718 move the printing stick 722 so that the tip of the printing stick 722 is located directly above the Pacinian point (point P). Then, as shown in Figure 43(b), the printing stick 722 is lowered in the Z-axis direction, the tip of the printing stick 722 is placed on the palm of the hand, and the Pacinian point (point P) is marked.

[0186] Thereafter, for example, the palm is photographed by the 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), as shown in Figs. 39(a) and (b) relating to the "first embodiment of the invention of a method for identifying Pacinian points." Then, as shown in Figs. 39(a) and (b), an auxiliary tool (support jig) is produced, and marks are made on the palm via the auxiliary tool, thereby indicating the exact positions of the Pacinian points on the palm.

[0187] Alternatively, instead of the above-mentioned flat printed auxiliary tool, a three-dimensional auxiliary tool (also called a "3D support tool," "3D tool," or "template") may be created. Figure 44 shows the steps to create and use a three-dimensional auxiliary tool from left to right. Also, the lower left part of Figure 46 shows how to identify the Pacinian points when using a three-dimensional auxiliary tool.

[0188] 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 of 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).

[0189] 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 line of Figure 44, the 3D scan data is used to create female mold data for making a palm mold 748 in cooperation with 3DCAD (reference number 742 in Figure 46) (S780).

[0190] When importing 3D scan data into 3DCAD, the 3D scan data can be imported into a PC (personal computer) from the communication interface of the 3D scanner 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 3DCAD from the numerical data sheet created in the spreadsheet software. In this way, after the 3D scan data is imported into the 3DCAD, the 3DCAD corrects the data as necessary (such as multiplying a predetermined coefficient). In the spreadsheet software, the coefficients of each part (various coefficients used to calculate variables) can be listed, and the coefficients of each part can be imported from the spreadsheet software into the 3DCAD. It is also possible to perform calculations using the coefficients in the spreadsheet software, and the calculation results can be imported into the 3DCAD. The design values ​​of the female mold data determined (or imported into the 3DCAD) 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, the description of such data transmission and reception will be omitted where appropriate.

[0191] Next, in cooperation with a 3D printer (744 in FIG. 46), a palm mold (also called a "female mold" or a "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.

[0192] The Patini point is also reflected when forming the palm mold (3D jig) 748. A hole 754 into which a writing implement 752 such as a ballpoint pen can be inserted is made at the position of this Patini point, and an auxiliary tool 756 is fabricated. Then, the user's hand is placed so as to fit into the recess 750 of the auxiliary tool 756, and the writing implement 752 is inserted into the hole 754, and a mark is made on the user's palm (S800).

[0193] According to the invention of the method for identifying the Pacinian points (second embodiment), the Pacinian points can be identified accurately, as in the first embodiment. In addition, since the Pacinian points are identified using AI, it is not necessary to manually search for the Pacinian points every 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 when using the device 200.

[0194] Figure 76 shows an example of an integrated system that integrates the first embodiment (Figures 34 to 39) and the second embodiment (Figures 40 to 46) of the invention related to the system (and method) for identifying Pacinian points. By combining the invention related to the system (and method) for identifying Pacinian points in this way, it is possible to configure an integrated identifying system (and method).

[0195] The upper left part of Fig. 76 shows a first embodiment of the invention related to a system (and method) for identifying Pacinian points, and the lower left part shows a second embodiment. In the first embodiment shown in the upper left part, the Pacinian points of a subject are identified through a "linear" "measurement" using a linear guide (reference number 604 in Figs. 36 and 37), as shown as "XY position discovery."

[0196] On the other hand, 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 undergo "AI calculation" by an "AI system", and the subject's Pacinian points are identified as shown as "XY position discovery" (corresponding to steps S712, S722, S732, S742, and S750 in Figure 46).

[0197] Thereafter, a 2D jig or a 3D jig is produced through the steps of "stamping" and "photographing" common to both embodiments. In the first embodiment (FIGS. 34 to 39), "stamping" and "photographing" refer to marking with a marker or the like for producing a 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).

[0198] Thereafter, it is possible to proceed to a process for producing not only the 2D jig (transparent plate 622) of the first embodiment (FIGS. 34 to 39) but also the 3D jig (palm-shaped mold 748) of the second embodiment (FIGS. 40 to 46), and produce the 3D jig (palm-shaped mold 748). It is also possible to proceed from the process according to the second embodiment (FIGS. 40 to 46) to a process for 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 a relatively high cost due to three-dimensional modeling, a choice can be given to the user. A user who has financial means can select a 3D tool (transparent plate 622), while a user who does not have financial means can select a 2D tool (transparent plate 622). In this way, a variety of tool selections can be realized.

[0199] [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.

[0200] First, the reason why an automatic design method as described below is necessary is to maximize the effect of the device 200. That is, the size of the palm of the hand differs from person to person, and the position of the Pacinian corpuscles also differs from person to person. Therefore, in order to maximize the effect of the device 200, it is necessary to provide the device 200 that is tailored to the size of each individual user (personalized).

[0201] For example, when making custom-made clothing, predetermined 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.

[0202] (Embodiments of the invention relating to an automated design system) First, the positions of the Pacinian points on the palm of the hand of the person being measured 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) or the like (step (S) 800). Of these measurements, the measurement of the position of the Pacinian points 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 positions of the measured Pacinian points (points P) are marked with a marker.

[0203] In measuring the positions of the 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.

[0204] 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.

[0205] The measurement of these positions and lengths can be determined, for example, as positions and lengths on a coordinate system with the origin being any part of the palm (the tip of the little finger, the tip of the middle finger, the tip of the thumb, the center of the wrist, etc.) Alternatively, without being limited to this, the positions and lengths can be determined in other ways.

[0206] 47(b) shows the positions of the hand (here, the left hand) when gripping a prototype (here, designated by the reference symbol 200) having the same function as the tool 200. By passing the little finger and ring finger through the ring portion 230 and gripping the tool 200, the grip line D formed by the little finger and palm is roughly on a circular arc.

[0207] Based on the measurement results of 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 using, for example, a 3D printer. In addition, the bone model 810 is created so as to reflect the positions of K1 to K4 and the lengths of L1 to L3 described above.

[0208] 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 at the base of the metacarpal bone on the little finger side of the palm is designated as K4.

[0209] Furthermore, the length of the distal phalanx is defined as L1, the length of the middle phalanx is defined as L2, the length of the proximal phalanx is defined as L3, and the length of the metacarpals is defined as L4.

[0210] To avoid complicating the explanation and illustration, explanations of other fingers and other parts of the palm (the ball of the foot, the base of the four fingers, etc.) are omitted here, but their positions and lengths are also measured in the same way, and the measurement results are reflected in bone model 810. Then, bone model 810 is obtained that is tailored to the hand of the person being measured.

[0211] When creating the bone model 810, the measurement results of the positions of the Pacinian points and the positions of the finger joints are converted into numerical information, and are input, for example, into a numerical form of a spreadsheet software, and are imported from the spreadsheet software into the 3DCAD. The link between the spreadsheet software and the 3DCAD can be performed, for example, in the same manner as described above. In the 3DCAD, calculation processing is performed, such as multiplying the basic bone model information by a coefficient that is determined in advance according to the conditions of the person to be measured (for example, information on age, sex, and physical build). The calculation results of the 3DCAD are imported into a 3D printer, and the bone model 810 is formed by the 3D printer. Note that the creation of the bone model 810 can be omitted if an instrument that satisfies the person to be measured can be created by measurement using a dummy grip 880, which will be described later.

[0212] 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 input, for example, into a numerical sheet of a spreadsheet software, and is input into 3DCAD in the same manner as in the case of creating a bone model 810. FIG. 49 illustrates an example of 3D scan data displayed on a monitor device. In the 3DCAD, calculation processing such as multiplication by a predetermined coefficient according to the subject's conditions (for example, information on age, sex, and physical build, etc.) is performed. The calculation result of the 3DCAD is input 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. Furthermore, the positions K1 to K4 of the joints and the lengths of the joints of the hand model 820 match those of the bone model 810. Here, in FIG. 49, the display image is inverted in order to match the orientation of the hand to FIG. 47(a).

[0213] Fig. 50 shows an image of the created bone model 810 and hand model 820 arranged side by side. Fig. 51 shows an image of the hand model 820 placed over the bone model 810. Here, in Fig. 50 and Fig. 51, the displayed image is inverted to match the orientation of the hand with Fig. 47(a).

[0214] By creating 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 bone model 810 described above, the creation of hand model 820 can be omitted if an instrument that satisfies the subject can be created by measurement using a dummy grip, which will be described later.

[0215] 52, a dummy grip 880 is prepared that has a size (outer dimensions) similar to that of the instrument (200) and imitates the instrument (200), and the subject is asked to hold the dummy grip 880. Then, while holding the dummy grip 880, the shape of the subject's hand is 3D scanned by a 3D scanner (S840). At this time, the dummy grip 880 is held so that a gap 882 is formed between the dummy grip 880 and the little finger.

[0216] The 3D scan data acquired by the 3D scan is imported into, for example, a numerical data sheet in a spreadsheet software, and then imported from the spreadsheet software into 3DCAD (S850). In the 3DCAD, 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 3DCAD, calculation processing 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.) is performed (S870).

[0217] 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 part 230 of the instrument 200 are determined, and the determined sizes are used as the design values ​​of the ring part 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).

[0218] Here, the reason for using a dummy grip 880 instead of the tool 200 when 3D scanning is to prevent the acquired 3D scan data from becoming overly complex and to facilitate the measurement of the little finger and ring finger.

[0219] Fig. 53 shows the subject's hand with the little finger and ring finger bent. The 3D scan data acquired when creating bone model 810 is used after changing the parameters so that the little finger and ring finger are bent as shown in Fig. 53. Then, the data in the state where the little finger and ring finger are bent and gap 882 (see Fig. 52) is formed is used to perform design on the 3D CAD as described above.

[0220] 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 calculated 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 portion 210 and the ring portion 230 M2: Width of the main body 210 (X-axis direction) M3: Inner diameter of pinky ring 231 M4: Height of fixture 200 (Z-axis direction) M5: Width of ring part 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

[0221] Based on the design data thus obtained, the main body 210 and the ring portion 230 are produced by a 3D printer or the like (S890). Then, the instrument 200 is assembled using the main body 210, the pressing portion 220, and the ring portion 230 as components. As a result, a custom-made instrument 200 in which the pressing portion 220 accurately contacts the Pacinian point is provided to the subject.

[0222] Fig. 55 shows that the shape and size of the instrument 200 can be changed by such a design method. For example, a design change is made to a standard size instrument 200 (standard product, shown by solid line) for a custom-made product, and the position of the ring portion 230 (only the pinky ring is shown here) is moved to a position away from the main body portion 210, as shown by a 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 joint and the main body portion 210.

[0223] By employing the above-described automatic design system and automatic design method, it becomes possible to custom-make the appliance 200. In addition, it becomes possible to provide the appliance 200 of an optimal size according to individual differences and the growth of the child.

[0224] It should be noted that rather than redesigning the device 200 every year or every few years, it is also possible to adopt, for example, the following provision format. First, a plurality of devices 200 with different sizes of parts and different positional relationships of parts are manufactured and stored in a store or business. Then, at set intervals (every year or every few years, etc.), measurements of the user's palm are taken (3D scans may be performed). Then, based on the results of the measurements, an appropriate device 200 is selected and lent to the person to be measured.

[0225] Figure 77 shows an example of an integrated system of the invention of the integrated system relating to the Pacinian point identification system (and identification method) shown in Figure 76 and the invention relating to the 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).

[0226] "Pacinian point identification" shown in the upper left of Fig. 76 is a process for identifying the positions of the Pacinian points. This "Pacinian point identification" corresponds to the measurement of the positions of the Pacinian points (S800 in Fig. 56) in the embodiment related to the automated design of instruments (Figs. 47 to 56). The latter "dummy measurement" corresponds to the process (S840 in Fig. 56) of scanning a hand holding a dummy grip 880 with a 3D scanner as shown in Fig. 52.

[0227] The latter stage, "automated design," corresponds to the process (S850 to S880 in FIG. 56) of importing the 3D scan data into 3D CAD via a spreadsheet software, and determining the size and positional relationship of each part while performing calculations in the 3D CAD. And, "production" corresponds to the process (S890 in FIG. 56) of forming the instrument 200 using a 3D printer.

[0228] 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 "photography" on the left side of the lower part corresponds to photography in exploring the positions of Pacinian points (search, first embodiment) and photography in identifying the positions 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.

[0229] [Modifications Related to Ring Portion 230] Next, modified examples of the ring portion 230 in the above-mentioned ring model instrument 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. Also, they can be manufactured by the above-mentioned automated design.

[0230] The function of the ring model tool 200 as described above can be achieved in the same manner 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 tool 200 similar to that shown in FIG. 31 and FIG. 32, and this tool 200 includes a ring portion 230 in which two rings (pinky finger ring 231 and ring finger ring 232) are formed as described above. Hereinafter, this type is considered as the standard type for the ring portion 230.

[0231] It should be noted that the device 200 shown in Figure 58(a) is turned upside down with the pressing portion 220 facing forward compared to the device 200 shown in Figure 32, and the positional relationship between the main body portion 210 and the ring portion 230 is also slightly different.

[0232] 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) is partially removed to connect the internal spaces of the two rings 231 and 232 into one. Fig. 58(c) shows a type of ring part 230c having only one ring (pinky ring 231 in this case).

[0233] Figures 58(d)-(f) show a type in which the tip side of ring portions 231a-231c in Figures 58(a)-(c) is cut obliquely (here, so as to become 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 portions 230b-230f can also prevent rotation around the Z axis (left and right rotation), and can exhibit the same position fixing function as the instrument 200 of this embodiment.

[0234] [Modifications Related to Pressing Section 220] Next, there will be described various modified examples relating to 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 thereof will be omitted as appropriate.

[0235] (First Modification of Pressing Part 220) In the first embodiment described above, it has been explained that it is preferable to form a space around the contact part 21 (Pacinian ball) of the pressing part 20 of the instrument 1 so as not to stimulate sensory receptors other than the Pacinian corpuscles when the contact part 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 part 220A (particularly the contact part 221) is optimized.

[0236] For example, if the entire (or most) part of the pressing part 220 (here, 220A) or the contact part 221 (here, 221A) is spherical, if the radius of the sphere is too large, the arc (spherical surface) of the contact part 221A that contacts and presses against the palm of the hand will also be large. Then, the arc (spherical surface) that presses the Pacinian 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 an appropriate amount of force.

[0237] Also, 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 becomes difficult to transmit an appropriate pressing force to the Pacinian corpuscles. Also, the size of the palm of each individual is usually different for each element (attribute) such as an adult, child, woman, or man, and the radius at which the pressure of the contact portion 221 (Pacinian ball) is appropriately felt is different.

[0238] Considering these factors, it is most effective to make the contact portion 221A spherical like the device 1 and device 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. For example, when the radius is set to R4 within this range, the contact portion 221A suitable for a female child (girl) is obtained. When the radius is set to R10, the contact portion 221A suitable for an adult male (adult man) is obtained. According to the research by the inventors, for an average-sized Japanese adult female, R7 to 8 is suitable, and for a larger-sized person, R8 to 10 is suitable. For a smaller-sized person than the average-sized Japanese female, R4 to 7 is suitable.

[0239] (Second Modification of Pressing Part 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 midway, so a ring-shaped line is drawn in the middle of the second contact portion 221B2.

[0240] 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 spherical shape, and the radius R A For example, the size is about R4 to R10.

[0241] Radius R of the first contact portion 221B1B R is about 0.5 to 5 (R A The tip side of the second contact portion 221B2 is a small-diameter portion that is continuously connected to the first contact portion 221B1, and the radius R C (Horizontal radius in the drawing) is the radius R of the first contact portion 221B1 B The base end side of the second contact portion 221B2 is a portion on the large diameter side, and the radius R D is R A It is a smaller value than

[0242] By making the shape of the pressing part 220B a multi-stage sphere as shown in Fig. 60(a) and (b), it is possible to directly apply a stronger stimulus to the precise Pacinian point using the first contact part 221B1 at the tip. Furthermore, the first contact part 221B1 at the tip allows the pressing part 220B to be satisfactorily inserted into the palm of the hand. As a result, the contact part 221B (Pacinian ball) is prevented from slipping, and the contact part 221B (Pacinian ball) can be prevented from slipping and moving even if the user changes his / her posture during exercise.

[0243] The shape of this second modified example allows the first contact portion 221B1 to function like a pivot, making it possible to continue to press accurately on the Pacinian point without it shifting position. As mentioned above, the Pacinian corpuscles are sensory receptors measuring about 1 mm in size, so preventing the position of the pressing portion 220B from shifting is important for accurately stimulating the Pacinian point. Also, if the diameter of the first contact portion 221B1 is excessively small, there is a possibility that excessive pain will be felt when pressing. For this reason, the radius R B It is preferable that R is about 0.5 to 5.

[0244] In the second modification, 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 first contact portion 221B1 presses the palm, the second contact portion 221B2 located closer to the base end than the first contact portion 221B1 and the like function as a stopper. This prevents excessive sinking or pressure from occurring when pressing.

[0245] It is also possible to determine an appropriate degree of pressure depending on 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).

[0246] 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 shape or a pyramid shape, as 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 circumferential surface to make it easier to understand the three-dimensional shape of the pressing portion 220B. FIG. 61(a) illustrates a first contact portion 221B11 that is cone-shaped and further has a curved tip portion (which may be a spherical tip). In this case, the curved surface of the first contact portion 221B11 can be a curved surface equivalent to a spherical surface with R0.5 to 5.

[0247] 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 in the first contact portion 221B12 shown in FIG. 61(b), the whole may be cylindrical, and the tip may be a flat surface. Furthermore, the tip portion 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 approximately equal 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.

[0248] (Third Modification of Pressing Part 220) Fig. 62 shows a schematic diagram of a pressing part 220C according to a third modified example. This pressing part 220C has a height adjustment function. As explained above, the expansion degree of the range of motion of the joint changes depending on the pressure applied to the Pacinian corpuscles. When the pressure is changed to increase stepwise (for example, when the level is changed in the order of weak, medium, and strong), it is known that the range of motion of the joint is expanded most widely when the pressure is set to a strong level up to a certain pressure.

[0249] Figure 63 shows, from top to bottom, photographic images of lateral flexion in the following cases: when using bare hands (holding nothing), 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 greater than the strong level (strongest).

[0250] According to 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 level, medium level, and strong level. 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 position of the arm is slightly higher in the strongest level compared to today's level.

[0251] In this way, when the pressure exceeds the strong level, even if the force applied from the user's fingers (here, the little finger and the ring finger) to the tool 200C 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 thus 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.

[0252] Fig. 62 shows a schematic example of a mechanism for maximizing such an effect. A male screw is formed on the shaft 222C connected to the pressing portion 220C, and the shaft 222C is screwed into a nut 242 fixed to the main body 210C. For example, when a user holds the pressing portion 220C and rotates it forward or backward around the axis, the shaft 222C advances or retreats relative to the main body 210C (moves in the forward or reverse direction of the Z axis), and the amount of protrusion of the pressing portion 220C relative to the main body 210C changes. The shaft 222C and the nut 242 constitute a protrusion amount variable mechanism, and the amount of protrusion of the pressing portion 220C changes due to the protrusion amount variable mechanism.

[0253] By adopting such a mechanism, the height of the pressing part 220C can be adjusted, and a suitable pressure generating function for each user can be realized. Note that the mechanism for adjusting the height of the pressing part 220C is not limited to the one exemplified in Fig. 62, and can be modified in various ways. Also, in Fig. 62, the ring part is omitted from the illustration.

[0254] (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), similar to the example shown in Figure 62, the height of the pressing portion 220D is adjustable. 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 formed in a stepped shape and has a flange portion 246 that protrudes in the radial direction.

[0255] A columnar space 248 is formed in the main body 210D. The shaft 222D is inserted into the space 248 so as to be freely displaceable in the axial direction, with the flange 246 positioned within the space 248. A portion having a female thread is formed in a predetermined range on the inner circumferential surface of the space 248, and a disk 250 is screwed into the main body 210D.

[0256] A coil spring 252 is interposed between the disk portion 250 and the flange portion 246 of the shaft portion 222D. A 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 contacts the disk portion 250 and the flange portion 246.

[0257] A groove (driver groove) 254 for a flathead screwdriver is formed in the center of the plate surface of the disk part 250 located opposite to the coil spring 252. A lid 256 is attached to the main body part 210D, and one end (the upper end in Figs. 64(a) and (b)) of the space part 248 is closed in an openable and closable manner by this lid 256. The lid 256 can be removed from the main body part 210D by the user pulling it up by hooking his / her fingers on it, and can be inserted into the space part 248 to close the space part 248 (it is detachable).

[0258] 64(a), when the pressing portion 220D is not subjected to an external force in the axial direction, the shaft portion 222D is in a state of protruding 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 engagement of the flange portion 246 with the main body portion 210D.

[0259] Fig. 64(b) shows a state in which pressing portion 220D is subjected to an external force in the axial direction. In this case, coil spring 252 is compressed and elastically deformed via flange portion 246, and shaft portion 222D sinks into space portion 248 depending on the magnitude of the external force. Then, the amount of protrusion of pressing portion 220D from main body portion 210D (height of pressing portion 220D) becomes smaller (height becomes lower) compared to the state in which no external force is applied as shown in Fig. 40(a).

[0260] 64(b), shaft portion 222D is in contact with disk portion 250, and pressing portion 220D and shaft portion 222D are stopped as shaft portion 222D hits disk portion 250. In other words, when shaft portion 222D is retracted, disk portion 250 functions as a stopper that determines the limit of the amount of retraction.

[0261] 64(a) and (b), the height of pressing portion 220D can be adjusted (the amount of protrusion can be changed) in the same manner as in the example shown in Fig. 62. Furthermore, in the example shown in Fig. 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 coil spring 252.

[0262] 64(a) and (b), a removable lid 256 is provided on main body 210D, and a driver groove 254 is provided on disk 250. Lid 256 is screwed onto main body 210D and contacts coil spring 252. For these reasons, the elastic restoring force of coil spring 252 can be changed by removing lid 256 from main body 210D and using a flathead screwdriver to rotate disk 250 forward or backward around the axis.

[0263] Therefore, for example, even if the user grips the tool 200D with the same force, the pressing force of the pressing portion 220D can be finely changed depending on the position of the disk portion 250 and the characteristics of the coil spring 252 (such as the spring constant).

[0264] The mechanism for adjusting the height of the pressing portion 220D is not limited to the one illustrated in Figures 64(a) and (b) and can be modified in various ways. Also, in Figures 64(a) and (b), the ring portion is not shown.

[0265] (Fifth Modification of Pressing Portion 220) 65 is a schematic diagram of a pressing part 220E according to a 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 a bag (not shown) when the user carries the appliance 200E in the bag.

[0266] 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 adopted. For example, it is conceivable to adopt 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.

[0267] Also, in order to make it easier to remove the stored pressing portion 220E from the main body portion 210E, it is possible to have at least a part of the pressing portion 220E exposed from a hole or a notch in the main body portion 210E.

[0268] [Modifications Related to the Main Body 210] Next, there will be described various modified examples relating to 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 thereof will be omitted as appropriate.

[0269] (First Modification of Main Body 210) Fig. 66 shows 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 of 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 the shaft 222F (and the pressing portion 220F) as a reference. The shaft 222F is connected to the main body 210F via a hinge portion 262. Various types of hinge portion 262 can be used.

[0270] For example, it is conceivable to adopt a hinge portion 262 that can stop the main body portion 210F with respect to the shaft portion 222E by frictional force. It is also conceivable to adopt a hinge portion 262 that has a mechanism (such as a ratchet mechanism) that can stop the shaft portion 222E in multiple stages of three or more stages.

[0271] 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 configure the ring portion 230F from a material such as a flexible 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.

[0272] (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 (omitted in Fig. 67) that has passed through the ring portion 230. 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.

[0273] [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.

[0274] (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 an internal 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.

[0275] The vibration motor 312 includes an oscillator (weight) 340, and constitutes a vibration unit together with the oscillator (weight) 340. The vibration motor 312 rotates and displaces the oscillator 340 in an eccentric state, and generates vibrations in the XY plane due to a change in the center of gravity position. A pressing unit 320 is attached to the vibration motor 312 via a connection unit 322. Although not shown in the drawings, the vibration motor 312 may be of a type in which the oscillator 340 is built into a case and is made into a unit. In this case, the vibration motor 312 can be used as a vibration unit.

[0276] Vibration motor 312 is controlled by computer 314 and rotates to generate vibration at a predetermined frequency (for example, 150 to 400 Hz). The vibration generated by vibration motor 312 is transmitted to pressing portion 320, which also vibrates in the same manner. The frequency of vibration motor 312 is changed under the control of computer 314. Power for vibration motor 312 and computer 314 is supplied by built-in battery 316.

[0277] Inside the main body 310, the vibration motor 312 is surrounded by a vibration-proof case 342. The vibration-proof case 342 has a function of preventing vibrations generated by the vibration motor 312 from being transmitted to the main body 310.

[0278] In Fig. 69, reference numeral 344 denotes a lid that covers the opening of the vibration-proof case 342 and through which the connection part 322 passes. Furthermore, reference numeral 346 in Fig. 69 denotes a memory device 350 provided in the main body part 310. The memory device 350 can store data for controlling the vibration motor 312, and the like.

[0279] 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.

[0280] According to such an instrument 300, the pressing part 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 part 310 (the Z-axis direction). Therefore, in addition to achieving the same effect as the above-mentioned instrument 200, it is possible to apply vibration to the Pacinian points. And, compared to the above-mentioned instrument 200, it is possible to selectively apply pressure stimulation to the Pacinian corpuscles more effectively.

[0281] A characteristic of the Pacinian corpuscles is that they are receptors that sense pressure and vibration. Furthermore, the Pacinian corpuscles receive vibrations of 100 to 300 Hz, and are most sensitive to vibrations of around 200 Hz. By utilizing such characteristics of the Pacinian corpuscles and actively applying pressure stimuli, it is possible to further improve the effect of using the instrument 300.

[0282] Furthermore, since the vibration frequency can be changed, it is possible to generate vibrations and pressure (pressure changes) in accordance with the tempo, rhythm, melody, and strength of music (including voice). Stimuli such as music can 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 bodily sensation information from the Pacinian corpuscles. Furthermore, the instrument 300 can function as a communication tool with the user via vibrations and pressure (pressure changes). In addition, communication can be achieved using the palm of the hand, where the Pacinian corpuscles are located, as if it were a second ear.

[0283] [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 of a ring type 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.

[0284] (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 this 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).

[0285] The main body 410 of the device 400 is provided with a vibrator 412, a computer 414, and an internal battery 416. Of these, various general vibrators that vibrate when electricity is applied can be used as the vibrator 412. For example, a piezoelectric element or other piezoelectric element that generates vibration in the Z-axis direction can be used as the vibrator 412.

[0286] A vibration stick (vibrator) 444 is attached to the vibrator 412. A round bar or a square bar can be used as the vibration stick 444. 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.

[0287] The vibration stick 444 is inserted concentrically into the cylindrical connecting part 422 and penetrates the connecting part 422 and the pressing part 420. In the device 400 of the fourth embodiment, the connecting 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 connecting part 422 and the pressing part 420 and vibrates in the axial direction (Z-axis direction) within the connecting 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, about less than 1 mm) from the pressing part 420.

[0288] Regarding the relationship between such pressing portion 420 and vibrating stick 444, for example, a part of vibrating stick 444 (here, the lower end part) can be incorporated into pressing portion 420, and pressing portion 420 can be configured to include a part of vibrating stick 444.

[0289] 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 under the control of the computer 414. Power for the vibrator 412 and the computer 414 is supplied by an internal battery 416 (a button-type battery in this case).

[0290] A position sensor 446 and a pressure sensor 448 are provided as a usage state detection section (and a state detection section) inside the main body 410. These detect information related to the usage state, such as the amount of movement and the gripping force, when the tool 400 is being held and used by a user.

[0291] Of these, the position sensor 446 is for detecting the position of the instrument 400 in space. As the position sensor 446, for example, one that detects changes in acceleration (acceleration sensor) can be adopted. By integrating the output of the acceleration sensor, it is possible to obtain information on speed and displacement. The output signal (here, an acceleration signal) of this position sensor 446 is input to the computer 414, and the displacement amount of the instrument 400 can be calculated by the computer 414.

[0292] The pressure sensor 448 detects the reaction force (gripping force) when the tool 400 is held between the palm and the fingers (pinky finger and ring finger) 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.

[0293] The outputs of the position sensor 446 and the pressure sensor 448 are used for the calculations of the computer 414, and the calculation results of the computer 414 are stored in a storage device 450. As the storage device 450, various memory devices provided in the instrument 400 can be used.

[0294] 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. Also, a built-in memory of the computer 414 may be used. Also, data for controlling the vibration motor 312 may be stored in the storage device 450 in advance.

[0295] 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 transmitted 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 via, for example, a USB cable or the like, or may be performed by a wireless connection via Wi-Fi, Bluetooth (registered trademark), or the like.

[0296] Examples of external devices include smartphones, mobile phones, tablet terminals, notebook PCs, desktop PCs, e-book readers, wearable computers, portable game consoles, etc. Furthermore, the external output destination may be a server device of a service provider connected via a communication network such as the Internet.

[0297] 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.

[0298] Such an instrument 400 not only provides the same effects as the instruments 200 and 300 described above, but also enables state detection by a position sensor 446 and a pressure sensor 448. The instrument 400 can display the results of state detection and display information based on the results by providing a display device such as a liquid crystal display. Furthermore, the instrument 400 can cooperate with external devices by using a communication function.

[0299] [Invention relating to application to user information provision systems] Next, the application of the devices 1, 200, 300, 400, etc. of each of the embodiments 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 devices 1, 200, 300, 400, etc. of each of the embodiments can be appropriately selected and used, but when there is a particularly suitable device, the description will be given using the suitable device.

[0300] (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).

[0301] In the exercise promotion system 1000 shown in FIG. 71, an operating system 1010 of a management center (labeled "Health Education System" in FIG. 71), an information processing device (not shown) in a photography studio 1020, and communication terminals 1030 owned by each individual are connected via a communication network 1040.

[0302] The management center's operating system 1010 is constructed using a server device (not shown). The server device may be installed, for example, by an 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, and the like.

[0303] 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 a BIOS (Basic Input Output System) and an OS (Operating System) for causing 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 executing, with the CPU, various control programs that are stored in advance in a storage unit such as the ROM.

[0304] Here, the operating system 1010 may be configured by one server device or multiple server devices with distributed functions. The operating system 1010 may also be called an "operating device" or the like.

[0305] The information processing device of the photography studio 1020 may be a general desktop PC, a notebook PC, a server device, or the like. As described later, the information processing device of the photography studio 1020 enables videos captured by a camera in the photography studio 1020 to be distributed to individuals via a communication network 1040. The information processing device of the 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 system 1010 of the management center.

[0306] 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 electronic book reader, a wearable computer, a portable game machine, etc. 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, etc. (including the so-called cloud).

[0307] In this exercise promotion system 1000, an instructor 1022 uses an equipment (e.g., equipment 400) in a photography studio 1020 to perform exercise (grip exercise) while stimulating the Pacinian point. Examples of types of grip exercise include stretching, yoga, muscle training, etc., which are included in the above-mentioned uses. Furthermore, examples include model movements for various sports, rehabilitation movements, etc.

[0308] 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 the video to distribution.

[0309] 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 predetermined 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 operating system 1010 of the management center or storing it in the operating system 1010 of the management center and then distributing it to the communication terminal 1030.

[0310] Each individual's communication terminal 1030 is installed with application software (so-called app) that allows display of distributed videos and input related to the videos. In Fig. 71, the portion having the letters "APP" drawn over the communication terminal 1030 shows that the application software is installed in the communication terminal 1030.

[0311] Each individual also owns an implement (e.g., implement 400) and performs a 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 an implement (e.g., implement 400) becomes a participant in a grip exercise performed simultaneously around the world (a global simultaneous grip exercise), and while watching the communication terminal 1030, a large-scale grip exercise (a large-scale grip exercise) can be performed by 10 million people around the world at the same time (approximately 20 million people in FIG. 71).

[0312] In this way, a network is formed by the communication terminal 1030, the equipment (e.g., the equipment 400), and the brain of each individual that receives the neurotransmission signal from the equipment (e.g., the equipment 400). Using this network, an exercise promotion system 1000 is constructed with the aim of maintaining and improving the athletic ability of each individual.

[0313] Furthermore, the application software installed in the communication terminal 1030 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. In order 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).

[0314] 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.

[0315] Furthermore, the reference exercise information can be presented through vibrations or up-down movements (movement in the protruding direction of the pressing part 420) generated by the equipment 400. In this case, for example, the reference exercise information is presented to the user by generating vibrations or up-down movements in synchronization with the rhythm, tempo, etc. of a standard exercise by the equipment 400.

[0316] In this way, by presenting the reference movement information via the device 400, it is possible to generate a signal that is transmitted from the Pacinian corpuscles to the brain. Furthermore, when the reference movement information by video or music and the reference movement information transmitted from the device 400 are simultaneously combined (synchronized) and output, the visual information, the auditory information, and the information from the Pacinian corpuscles are transmitted to the user's brain in a unified manner. This makes it possible to transmit information in a novel manner that has never been seen before.

[0317] In the exercise promotion system 1000, a multifunctional tool 400 having a vibration function and an information collection function is used to detect the condition of each individual when a large-scale grip exercise is performed. The result of the condition detection is received by a communication terminal 1030 from the tool 400, and is transmitted from the communication terminal 1030 to an operating system 1010 in a management center via a communication network 1040. Here, the tool 400 can also have a function to communicate with the operating system 1110 via the communication network 1040.

[0318] 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, 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.

[0319] 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."

[0320] Among these, the grip monitor control system 1060 is a system that controls the contents 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.

[0321] The video distribution system 1070 is a system that controls the distribution of videos to the communication terminal 1030. In addition, the pressure / position movement analysis system 1090 is a system that receives the status information sent from the instrument 500 via the communication terminal 1030 and analyzes it.

[0322] In the operating 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, for each individual's information, comparative information such as rank and deviation value is calculated, and the obtained calculation results are transmitted to the relevant individual.

[0323] Information based on the calculation result (user information) is displayed, for example, on the communication terminal 1030 or the tool 400 and notified to the relevant individual (S1040). Examples of information displayed (presented) on the communication terminal 1030 or the tool 400 include the number of individuals (number of participants) participating in the large-scale grip exercise described above, and the ranking described above. This information indicates the position of each individual among the large number of people.

[0324] In this way, by sending and informing the relevant individual of their position among a large number of people, it is possible to stimulate the competitive spirit of participants in the large-scale grip exercise and motivate them to continue the exercise. Here, the process of generating information to be sent back to individuals using big data may be performed by statistical machine learning using AI, deep learning, or the like.

[0325] By displaying the number of participants and rankings as described above, grip exercise can be combined with playful elements. In other words, it has become difficult to find time to go to a gym or exercise these days due to dual-income households and the COVID-19 pandemic. As a result, there is an increasing demand for exercise that can be done alone in small spaces such as at home.

[0326] 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, each individual can be motivated to perform the grip exercise. For example, even if a person performs the grip exercise alone at the same time every day in his / her own place, he / she can realize that he / she is performing the grip exercise together with many people, which can encourage him / her to continue the grip exercise. The information (user information) presented to the user is not limited to information presented to the user instantly (in real time) based on collected information. For example, information related to the history of past exercise may be presented in units of one day, one week, one month, or one year. This point is the same for various embodiments and modified examples described below.

[0327] As described above, reference exercise information serving as a model for the user's exercise is transmitted, and the user can exercise based on the model, so that the user can exercise after obtaining information about appropriate exercise. After that, the operating system 1010 can obtain information on the acceleration, speed, and position of each individual's hand movements (use status information as status information) and provide feedback of personal user information to the user. This mutual communication allows the user to reflect on themselves (introspection, reflection, reflexion, etc.) and learn the relationship between their own body and exercise. Such a user information providing system can also be called an "exercise education and reflection system", etc.

[0328] It can be said that the exercise promotion system 1000 of this embodiment combines the 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, luck, 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.

[0329] According to the exercise promotion system 1000 of the present embodiment, a large-scale grip exercise adapted to various play becomes possible as a result of the distribution of the video and the mutual communication with the individual's status information corresponding to the video. It is also possible to combine the distribution of the video with audio encouraging participation in the grip exercise, or to encourage participation in the grip exercise by audio alone depending on the situation.

[0330] Such an exercise promotion system (user information providing system) 1000 can also be used as follows. First, the reference exercise information presented to the user is information conveying an exercise program tailored to each age group (assuming children to people in their 90s) created from the standpoints of physical education pedagogy, kinesiology 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.

[0331] In order to optimize a user's exercise in accordance with the reference exercise information, the rhythm and tempo of the exercise program are essential components. Therefore, it is necessary to present the exercise program to the user in accordance with the physical ability 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 has a melody added to the rhythm and tempo. The user exercises in accordance with a video or the like that matches the exercise program created with these points in mind.

[0332] After the user starts exercising, in the process of collecting status information, status information detection means (such as position sensor 446 and pressure sensor 448) installed in the equipment 400 transmits the status of the equipment 400, such as position data, movement acceleration data, changes in grip force, etc., of the equipment 400 to the operating system 1010.

[0333] Next, the operating system 1010 presents the analysis results to the user based on the analysis program. In the analysis, if it is determined that the user is performing an incomplete exercise or an exercise that does not meet the standard based on the various state information transmitted, an analysis is performed to determine which of the above-mentioned exercise 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 user's movement is selected, and the exercise task for the user is derived based on a predetermined derivation condition that integrates the quantitative and qualitative conditions of the movement.

[0334] The derived results are presented to the user, and the user can become personally aware of his / her own condition and begin to think about what he / she needs to improve. The user then continues exercising using the equipment 400 with a purpose to see improvements in his / her exercise. This cycle of user guidance and user behavior can be called a cycle of education and reflection.

[0335] (Second embodiment of the user information providing system according to the invention) Next, a second embodiment of the invention of the user information providing system will be described with reference to Fig. 72. Note that the same parts as those in the fourth embodiment of the equipment and the first embodiment of the invention of the exercise promotion system will be given the same reference numerals, and the description thereof will be omitted as appropriate.

[0336] As a user information providing 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 also a system that assumes that a large number of people (for example, 10 million people) will perform grip exercise.

[0337] In the exercise promotion system 1100 shown in Fig. 72, an operating system (indicated as "Health Education System" in Fig. 72) 1110 of a management center and a communication terminal 1030 owned by each individual are connected via a communication network (not shown). Although not shown, the same communication network as the communication network 1040 of the exercise promotion system 1000 according to the first embodiment can be applied to the communication network. Moreover, the operating system 1110 can also use a hardware configuration similar to that of the operating system 1010 according to the first embodiment.

[0338] Fig. 72 shows a case where the tool 500 is used in the exercise promotion system 1100. The tool 500 shown in Fig. 72 includes a vibrator 412, a computer 414, an internal battery 416, a position sensor 446, and a pressure sensor 448, similar to the tool 400 described in the fourth embodiment of the tool. The tool 500 has a vibration function and a state detection function.

[0339] The appliance 500 has a built-in communication circuit unit (not shown) and is capable of outputting the above-mentioned state information to the outside. This communication circuit unit (not shown) can also have the same configuration and function as the above-mentioned appliance 400. Here, the appliance 500 can also be provided with a function to communicate with the operating system 1110 via the above-mentioned communication network (1040 referring to FIG. 71).

[0340] Furthermore, the device 500 is provided with a display device 560, as shown in the lower left part 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 that shows a schematic representation of the internal devices of the main body 410 is shown on the right side of the bottom row, and the device 500 that shows a schematic representation of the outside of the main body 410 is shown on the left side. In other words, the internal and external configurations of one device 500 are shown side by side on the left side of the bottom row of Fig. 72.

[0341] In Fig. 72, the names of "total exercise result diagnosis system" and "real-time correction system" are separately described for the operating system 1110. In this operating system 1110, various internal systems operate, and exercise promotion information as user information is transmitted to the communication terminal 1030. As various internal systems of the operating system 1110, from the left, Fig. 72 illustrates a grip monitor control system 1160, a video distribution system 1170, a music vibration Hz tempo command system 1180, and a pressure / position motion analysis system 1190.

[0342] Of these, the grip monitor control system 1160, like the above-mentioned grip monitor control system (not shown), is a system that controls the contents displayed on the display device 560 of the tool 500. The video distribution system 1170, like the above-mentioned video distribution system (not shown), is a system that controls the distribution of videos to the communication terminal 1030.

[0343] The music vibration Hz tempo command system 1180 is a system that transmits information corresponding to the tempo of music (including background music for video) distributed to the communication terminal 1030 to the communication terminal 1030. Furthermore, the pressure / position movement analysis system 1190 is a system that receives status information sent from the instrument 500 via the communication terminal 1030, similar to the above-mentioned pressure / position movement analysis system (not shown).

[0344] In the management system 1110, similarly to the management system 1010 according to the first embodiment, 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 corresponding individual. Information based on the calculation results is displayed on the communication terminal 1030, for example, and notified to the corresponding individual.

[0345] More specifically, a video of the grip exercise taken in a photography studio 1020 (referring to FIG. 71) is distributed to an individual's communication terminal 1030 by a video distribution system 1170 of the operating system 1010. The individual who receives the video performs 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.

[0346] Musical pieces are distributed together with the video of the grip exercise. The music vibration Hz tempo command system 1180 of the operating system 1010 transmits command information for driving the vibrator 412 of the device 500 to each individual communication terminal 1030 in accordance with elements that affect the melody, such as the tempo, rhythm, melody, and strength of the music.

[0347] 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 illustrated in FIG.

[0348] 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 tool 500 displays the information received from the communication terminal 1030 on the display device 560.

[0349] 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 the movements larger, etc.), and other information that may be useful to the individual. In the example of Fig. 72, the display device 560 of the tool 500 displays the pressure (1.2 kg) with which the tool 500 is gripped, the number of grips (120), and the age (36 years old) estimated from the grip strength.

[0350] Also, the information to be notified to the individual may be based on the detection result (calculation result) of the walking or jogging speed, etc., compared with the previously stored personal information, judge the physical condition, and suggest taking a break or speeding up. Furthermore, it may be possible to issue a command to change the tempo of the exercise by using the vibration generated by the equipment 500.

[0351] In this way, it is possible to provide useful information (information such as suggestions, guidance, or advice) to an individual performing grip exercise via the operating system 1110. The useful information may be output 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 contents or audio output contents may be the same or different.

[0352] (Third embodiment of the invention of the user information providing system) 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 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.

[0353] As a user information providing 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.

[0354] Firstly, it is said that grip strength is proportional to overall muscle strength. Furthermore, a decline in physical flexibility is a cause of falls as people age. For example, at the beginning of "The Impact of Habitual Exercise on Health - Using Grip Strength as an Indicator" by Nakamaru Aoi et al., it is explained that "Grip strength has been 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 "Summary of Survey Results on Physical Fitness and Athletic Ability in 2014," which measured grip strength as an indicator of muscle strength and examined trends in changes associated with age. https: / / www.mext.go.jp / sports / b_menu / toukei / chousa04 / tairyoku / kekka / k_detail / 1368152.htm

[0355] Based on this idea, the exercise promotion system 1200 according to this embodiment uses the information collection function of the equipment such as the equipment 400 and the equipment 500 to collect data related to grip strength (step (S) 1200). This exercise promotion system 1200 can employ the same hardware configuration as the exercise promotion system 1000 according to the first embodiment.

[0356] In the exercise promotion system 1200 according to this embodiment, for example, the pressure of the little finger and ring finger of the individual 1210 gripping the tool 500 is detected and measured by the pressure sensor 448. The measurement result is 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.

[0357] Next, the position of the tool 500 is detected and measured by the position sensor 446 built into the tool 500. As described above, for example, an acceleration sensor 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 information on the position.

[0358] The measurement results relating to the gripping force and position are stored in the storage device 450 of the tool 500. In addition, a menu of measurement exercises is determined in advance and stored in the tool 500 and the operating system 1110. This "measurement exercise" means the exercise to be measured (measurement target exercise). Examples of the measurement exercise menu include forward bending and side bending.

[0359] When performing the measurement exercise, a file in which the measured grip force data (grip force data) and position data (position data) are saved is transferred to the management center's operating system ("Health Education System" referring to FIG. 72) via the communication terminal 1030 (S1210). The management center's operating system sets an origin using the position data of the tool 500, and calculates the value of an index based on this origin (S1220).

[0360] In the example of Fig. 73, the origin for an individual is set at the center of the upper part of the waist (around the navel position), 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) stretched straight up from the floor surface on which the individual is standing (the direction of the arm before side bending) and the direction of the arm during side bending.

[0361] Furthermore, a horizontal index (X) and a height index (Y) are also set. In the example of Fig. 73, the horizontal displacement of the hand position (horizontal displacement in the direction of lateral bending) is set to the value X1 of index X. Also, the value of index Y, which is the height of the hand from the floor surface before lateral bending, is set to Y0, and the value of the height of the hand from the floor surface during lateral bending is set to Y1.

[0362] These indices are indices that indicate the flexibility of an 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.

[0363] For these indices, data on a large number of people is collected in advance along with data (attribute data) such as age and sex, and AI learning is performed on the collected data for the purpose of calculating age. Then, based on the results of the AI ​​learning, age is calculated from the data on each of the indices 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).

[0364] 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).

[0365] 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). Then, it judges whether the notified exercise program is being performed as a habit based on the detection results of the position sensor 446 and the pressure sensor 448. It then refers to 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).

[0366] This display notifies the individual whether or not their flexibility has improved (whether or not the rejuvenation 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.

[0367] (Fourth embodiment of the user information providing system) 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 equipment (equipment 400, equipment 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.

[0368] As a user information providing 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 also promotes the exercise of each individual by mutual communication of information related to grip exercise. Furthermore, this exercise promotion system 1300 prevents the sensitivity of vibration in the Pacinian corpuscles from decreasing, and enables the effect of grip exercise to be continuously exerted.

[0369] First, as mentioned above, the Pacinian corpuscles are characterized by being receptors that sense pressure and vibration. Furthermore, the Pacinian corpuscles receive vibrations of 100 to 300 Hz, and are most sensitive to vibrations around 200 Hz. However, when a constant frequency of vibration is continuously applied, the Pacinian corpuscles are sensitive to the vibrations at the beginning, but if the state is maintained, the Pacinian corpuscles adapt to the vibrations and become less sensitive to the vibrations.

[0370] In addition, when gripping the instrument 500 and performing a gripping movement, 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 instrument 500 is maintained.

[0371] In the exercise promotion system 1300 of the present embodiment, by focusing on these points and applying them further, adaptation of the Pacinian corpuscles is prevented. More specifically, the frequency and pressure transmitted to the Pacinian corpuscles are changed in accordance with the tempo and rhythm of the music, thereby preventing adaptation of the Pacinian corpuscles. In addition, the pressure transmitted to the Pacinian corpuscles can be constantly changed by changing the gripping force and the vibration during the gripping movement.

[0372] As shown in Fig. 74, in the exercise promotion system 1300, the management center operation system 1310 is provided 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 a 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 such as the tempo, rhythm, and dynamics of a sound source affect the melody.

[0373] The tempo / rhythm command system 1340 performs data conversion on the tempo / rhythm / 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 vibration generated by the instrument 500.

[0374] 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 the sound source information include information identifying the music and sound source data of the music itself.

[0375] The communication terminal 1030 transmits a command to the instrument 500 by using a 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 as a 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 frequency of vibrations based on the vibration mode information. By changing the frequency of vibrations, it is possible to change the vibration intensity.

[0376] According to such an exercise promotion system 1300, it is possible to continuously change the stimulation to the Pacinian corpuscles by the grip exercise and the sound source 1320. The individual using the tool 500 can simultaneously perceive the auditory information from the ears and the somatic information from the Pacinian corpuscles in the brain. The individual using the tool 500 can perform the grip exercise more comfortably due to the synchronization between the auditory information and the somatic information.

[0377] The first embodiment (FIG. 71) to the fourth embodiment (FIG. 74) of the user information providing system (exercise promotion system in this case) according to the invention 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) information about the individual via the equipment (equipment 400, equipment 500, etc.) and receiving (downloading) information about the individual via the equipment or communication terminal 1030.

[0378] Furthermore, as described in the first embodiment (FIG. 71), reference exercise information serving as a model for the user's exercise is transmitted, and the user can exercise based on the model, so that the user can exercise after obtaining information about appropriate exercise. 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 equipment (such as the equipment 400 or 500). In this case, for example, the equipment (such as the equipment 400 or 500) can generate vibrations or up-down movements synchronized with the rhythm or tempo of a standard exercise, thereby presenting the reference exercise information to the user. In this way, by presenting the reference exercise information via the equipment (such as the equipment 400 or 500), it is possible to generate a signal that is transmitted from the Pacinian corpuscles to the brain.

[0379] Furthermore, when the reference motion information by video or music and the reference motion information transmitted from the device (such as the device 400 or the device 500) are simultaneously combined (synchronized) and output, the visual information, the auditory information, and the information from the Pacinian corpuscles are transmitted to the user's brain in a unified manner. This makes it possible to transmit information in a novel manner that has never been seen before.

[0380] After that, the exercise promotion systems 1000, 1100, 1200, and 1300 acquire information on each individual (usage status information as status information) through mutual communication 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 providing system can also be called an "exercise education and reflection system."

[0381] Since the information exchanged is personal information and the information given to the individual (feedback information) reflects the individual's situation, it is possible to create a situation in which a personal trainer (personal trainer) is making a diagnosis and creating indicators based on an individual's exercise menu, and providing guidance and advice (instruction, etc.).The individual who receives the guidance, etc. is then able to recognize whether their own exercise method (exercise situation) is going well, or whether it is excessive or insufficient.

[0382] Furthermore, by an individual recognizing his / her own exercise status and continuing daily exercise while improving the way he / she exercises, self-improvement can be achieved step by step, and as a result, a spiral up in the way the individual progresses in exercise can be expected. In addition, the mutual communication function that enables such a spiral up can also encourage individuals to have (including purchase) equipment (equipment 400, equipment 500, etc.).

[0383] [Other examples of information processed by devices] Next, another example of information processed by the tool (here, the tool 500) will be described. Note that the same reference numerals are used to denote parts similar to those of the tool (such as the tool 500) and the exercise promotion system according to the second embodiment of the invention (the exercise promotion system 1100, FIG. 72), and the description thereof will be omitted as appropriate.

[0384] The device 500 measures the gripping force (grip strength) and informs the individual using the device of the current gripping force, the number of grips made that day, the duration of the grip exercise, and the like. In the example of Fig. 75(a) and (b), the display device 560 of the device 500 is used as an indicator for informing the individual of the gripping force. Also, the device 500 (or the communication terminal 1030) is made capable of inputting and storing the most effective gripping force for the individual using the device. Then, if a target gripping force (target gripping force) is set, when the gripping force reaches the target value, this fact is notified. Examples of means for informing that the target has been reached include the display device 560 and a lamp (LED) of a predetermined color (e.g., green).

[0385] As another example, a sensor (health index sensor) for measuring a health index such as blood pressure is incorporated in 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 with the communication terminal 1030 is possible.

[0386] 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 (the operating system 1110 or the operating system 1310) is not limited to the information described above. For example, the appliance status information may be appliance failure information, lost information, or the like.

[0387] Regarding fault information of an appliance (such as the appliance 400 or the appliance 500), for example, a fault detection unit (state detection unit) may be provided inside the appliance (such as inside various main body parts). When the fault detection unit detects that the electrical current flowing through an electric circuit (including an electronic circuit) in the appliance is not normal, a signal indicating this and / or processed information are transmitted from the appliance to the operating system (operating system 1110 or operating system 1310).

[0388] Regarding information on the loss of an appliance (such as the appliance 400 or 500), for example, a location information system circuit unit (such as a GPS circuit unit) serving as a state detection unit may be provided in the appliance. Then, an operating system (operating system 1110 or operating system 1310) of the management center transmits the location information of the appliance to the communication terminal 1030 via a detection system (not shown). The communication terminal 1030 combines and displays map information and location information, and notifies the location of the appliance.

[0389] Although each embodiment has been described above, each embodiment can also be comprehensively described as follows: First, the exploration of the 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 Fig. 13(b) and Fig. 40), a mechanical exploration method (exploration methods such as those illustrated in Figs. 36 to 38), and an AI exploration method (exploration methods such as those illustrated in Figs. 45 to 46).

[0390] Furthermore, through various exploration methods, the hand of the instrument user is marked with the location of the Pacinian points, which are then used to create a positioning format (creation of 2D and 3D jigs) that improves the convenience of using the instrument, and for automatic design of the instrument (automatic design as exemplified in Figures 47 to 56).

[0391] 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 a 3D jig), the user can easily mark the position of the Pacinian points and confirm the position of the Pacinian points. Then, the user can smoothly start using the device on a daily basis. As a result, it is possible to promote exercise using the device and the habit of using the device.

[0392] This comprehensive approach to instruments can be referred to as an instrument provision system (instrument provision method) that includes a series of processes from instrument supply to utilization and the equipment required for that process.
