<Embodiment>
<Configuration of the embodiment>
FIG. 1 shows a configuration of a pressure measurement system according to an embodiment. The pressure measurement system PMS according to the embodiment is applied to the grounding portion of the toe when the foot of the person who receives the measurement of the pressure applied to the toe (hereinafter referred to as “measured person instep”) is grounded. In order to measure the pressure, as shown in FIG. 1, it includes a pressure measuring device PM, a pressure display device PD, and a communication channel TL.

  The pressure measuring device PM includes a control unit CT (PM), a main unit MN (PM), and a communication unit CM (PM). For ease of explanation and understanding, the following description assumes that only the left toe is measured, not both toes.

  The control unit CT (PM) includes a CPU 10, a ROM 20, and a RAM 30. The ROM 20 stores a program 40 for monitoring and controlling the operation of the pressure measuring device PM, in other words, the operations of the control unit CT (PM), the main unit MN (PM), and the communication unit CM (PM). Yes. The CPU 10 monitors and controls the pressure measuring device PM as a whole in accordance with the contents of the program 40 while using the RAM 30 as a work area.

  As shown in FIG. 1, the main unit MN (PM) includes a plurality (five) of detection units D1 to D5.

  2 is a perspective view showing the external appearance of the main unit, FIG. 3 is a front view showing the external appearance of the main unit, and FIG. 4 is a bottom view showing the external appearance of the main unit. As shown in FIGS. 2 to 4, the main body unit MN (PM) has a shape imitating the shape of a so-called five-finger sock as a whole. The main body unit MN (PM) is composed of fibers and the like, similar to general socks. The main unit MN (PM) can be attached to and detached from the foot of the person to be measured, and the shoe (the shoe SH shown in FIG. 8) can be attached to and detached from the foot to which the main unit MN (PM) is attached. .

  More precisely, the main body unit MN (PM) includes a main body portion B and convex portions C1 to C5 as shown in FIG. The main body portion B approximately approximates the shape of a five-finger sock, and accurately approximates the shape of a five-finger sock that does not have a portion corresponding to a finger. The convex portions C1 to C5 extend forward from the main body portion B, and more specifically, from the position corresponding to the position of the base of the toe in the main body portion B to the position of the tip of the toe. Extends to the corresponding position. The convex portions C1 to C5 have the shape of the toes, that is, the first heel (thumb), the second heel (index finger), the third heel (middle finger), the fourth heel (ring finger), and the fifth heel (small finger). Each has a simulated shape, and each has a size approximately equal to the size of the first to fifth ridges.

  In other words, the main body unit MN (PM) includes a bag-like cloth portion that covers the toes as a whole in a broad sense, and in the narrow sense, the five fingers (first to fifth heels). ) Including a bag-like cloth portion (convex portions C1 to C5) having a shape corresponding to a toe portion. About the latter, it is provided with only the bag-like cloth part (convex part C1-C5) which has the shape of what is called a finger sack like the below-mentioned modification 1 (illustrated in FIG. 5). Part B is substantially equal to nothing). In addition, convex parts may be connected like FIG. 5, and may be an independent convex part with which each finger | toe is mounted | worn.

  Here, the “bag” of the “bag-shaped cloth part” has at least a part to be attached to and detached from the toe, and the other part is closed by sewing, pasting, etc. It means that you only need to put your finger inside. The “cloth” in the “bag-shaped cloth portion” means that a representative material is cloth, and does not mean to exclude other materials such as paper and leather.

  As shown in the bottom view of FIG. 4, the main body unit MN (PM) is a finger on the outer bottom surface (the surface in contact with the shoe sole or insole) of the convex portions C1, C2, C3, C4, C5, that is, Detectors D1, D2, D3, D4, and D5 are provided at positions corresponding to the positions of the grounding portions of the first rod, the second rod, the third rod, the fourth rod, and the fifth rod, respectively. Here, the detection units D1 to D5 are arranged on the bottom surface inside the main body unit MN (PM) (the surface directly in contact with the foot) instead of being arranged on the bottom surface outside the main body unit MN (PM). You may arrange | position in the position corresponding to the position of the grounding part of 1st-5th base, ie, the position which contacts the grounding part of a toe. This arrangement, that is, that the detectors D1 to D5 are arranged on the bottom surface inside the main unit MN (PM), more precisely, between the main unit MN (PM) and the toes, It does not mean that other members such as thin socks and stockings are interposed between the detection units D1 to D5 and the toes. The convex portions C1 to C5 are at positions corresponding to the positions of the bases (not shown) of the respective toes of the foot in order to further reduce the positional deviation between the detecting units D1 to D5 and the toes. It is desirable to have a pressing force that presses the foot from the surface of the foot base toward the inside of the foot base. For example, since the convex portions C1 to C5 of the main unit MN (PM) are formed of a stretchable fabric, the main unit MN (PM) is fitted to the toes, that is, a pressing force is applied so as to fit. In addition, it is possible to reduce the displacement of the detection units D1 to D5.

  FIG. 5 is a bottom view showing an external appearance of Modification 1 of the main unit. As shown in FIG. 5, Modification 1 of the main unit MN (PM) is only the portion corresponding to the toes of the main unit MN (PM) shown in FIG. 4. Similarly to the main unit MN (PM) illustrated in FIG. 4, the main unit MN (PM) of Modification 1 also includes a main body B and convex portions C1 to C5. In the main body unit MN (PM) of the first modification, as in the main body unit MN (PM) illustrated in FIG. 4, the first rod, the second rod, the third rod, the fourth rod, Detectors D1, D2, D3, D4, and D5 are provided at positions corresponding to the positions of the fifth ground contact portions, respectively.

As shown in FIG. 6, the second modification of the main unit MN (PM) is in contrast to the first modification shown in FIG. 5, and the toe of the main unit MN (PM) shown in FIG. It consists of parts other than the part corresponding to. The main body unit MN (PM) of Modification 2 has a main body portion B, similar to the main body unit MN (PM) illustrated in FIG. 4, and is different from the main body unit MN (PM) illustrated in FIG. 4. And support members S1 to S5. In the main body unit MN (PM) of the modified example 2, the support members S1 to S5 extend from the position corresponding to the base of the finger in the main body unit MN (PM), and more at the tip of the support members S1 to S5. Precisely, the detection units D1 to D5 are provided at positions corresponding to the positions of the first to fifth ground contact portions of the person to be measured wearing the main body unit MN (PM) of Modification 2. . Here, the support members S1 to S5 correspond to “convex portions”.

  The detection units D1 to D5 illustrated in FIGS. 1, 4, 5, and 6 are pressure sensors. The pressure sensor may be any material, method, output element, base material, or the like. The pressure sensor method may be any of resistance wire type, diffusion type, capacitance type, mechanical type, etc., and the output element of the pressure sensor may be any of strain gauge, metal film, etc. Any of a diaphragm, a spring and the like may be used. More typically, for example, a pressure-sensitive conductive rubber sensor, a piezo sensor, a fabric sensor using a conductive fiber or a piezoelectric fiber, or a membrane sensor can be used as the pressure sensor.

  The detection units D1 to D5 may have any shape, and may be, for example, a circle or a rectangle. The circular diameter and one side of the rectangle are preferably 5 mm to 15 mm, for example, in view of the size of the toe area. The detectors D1 to D5 are preferably 2 mm or less in thickness, for example, in view of a sense of discomfort to the foot.

  The detection units D1 to D5 may be embedded in the fibers of the main unit MN (PM) made of fibers or the like, or may be attached by being attached to the surface of the fibers of the main unit MN (PM). If the detection units D1 to D5 are made of fibers, they may be knitted into the main unit MN (PM).

  It is desirable that the detection units D1 to D5 are entirely covered with a stretchable fabric from the viewpoint of wearing comfort on the foot.

  For example, the detection units D1 to D5 desirably have elasticity to cope with the movement of the toes, or the detection units D1 to D5 are connected to the main body unit MN (PM). In the case of attachment, it is desirable that the member (fabric or the like) for attachment has elasticity.

  The communication unit CM (PM) communicates with the pressure display device PD via the communication path TL. More specifically, the communication unit CM (PM) transmits data DT (toe pressure indicating toe pressure) to the pressure display device PD by near field communication (for example, NFC, Blue Tooth (registered trademark), ZigBee, WiFi). Hereinafter, abbreviated as “toe pressure data DT”). The “toe pressure data DT” includes an AD conversion value before conversion into a pressure value.

  Here, the communication unit CM (PM) corresponds to “transmission unit”, and the toe pressure data corresponds to “pressure data”.

  The control unit CT (PM) and the communication unit CM (PM) are preferably attached to any part of the measured subject's back. For example, as shown in FIG. 2, the main unit MN (PM) has a sock-like shape. If it is a thing, it can be attached or detached to the side surface of main body unit MN (PM) with which the to-be-measured person's back was mounted | worn.

  The control unit CT (PM), the main unit MN (PM), and the communication unit CM (PM) are connected by a wiring WR as shown in FIGS.

  As shown in FIG. 2, for example, the wiring WR is as light as possible and can be expanded and contracted in consideration of reducing the burden on the foot when the main unit MN (PM) is worn. Is desirable.

  The wiring WR may be, for example, a lead wire or a conductive fiber such as a plated fiber (a metal-plated fiber), or a mixture of conductive fiber and non-conductive fiber (for example, a main unit MN (PM)) The necessary areas of the non-conductive fabric (woven fabric and knitted fabric) that make up the fabric are printed with conductive fibers woven, conductive embroidery, and conductive paste as wiring WR. (Including those in which a conductive paste is printed after the base is printed).

  From the viewpoint of stretchability, it is desirable that the wiring WR has a stretchable base material (for example, a film or sheet) printed with stretchable conductive paste, or twists conductive fibers. The conductive yarn itself may be provided with stretchability by thread processing such as. The conductive yarn can also be wired by bonding to a stretchable fabric.

  The wiring WR is detachable by being attached to the main unit MN (PM).

  The connection between the control unit CT (PM), the main unit MN (PM), the communication unit CM (PM) and the wiring WR is sufficient as long as an electrical connection is established. A separate connector may be attached and connected by the connector, may be bonded with a conductive paste, or may be sewn with a conductive thread. When the detection units D1 to D5 are fabric type sensors, the detection unit D1 to D5 and the wiring WR may be integrally woven or knitted into one piece of fabric.

  Next, the pressure display device PD is, for example, a personal computer, and includes a control unit CT (PD), a display unit DP (PD), and a communication unit CM (PD).

  Control unit CT (PD) is provided with CPU50, ROM60, and RAM70 similarly to control unit CT (PM) of pressure measuring instrument PM.

  The ROM 60 stores a program 80 for monitoring and controlling the operation of the pressure display device PD, in other words, the operation of the control unit CT (PD), the display unit DP (PD), and the communication unit CM (PD). .

  In accordance with the contents of the program 80 stored in the ROM 60, the CPU 50 monitors and controls the operation of the pressure display device PD as a whole, with the RAM 70 as a work area.

  The display unit DP (PD) is made of, for example, a liquid crystal or an organic EL, and displays toe pressure data DT.

  The communication unit CM (PD), in order to receive the toe pressure data DT from the pressure measurement device PM via the communication path TL, is short-range wireless communication as with the communication unit CM (PM) of the pressure measurement device PM. (For example, NFC, Blue Tooth (registered trademark), ZigBee, WiFi).

  Here, the communication unit CM (PD) corresponds to a “reception unit”.

  Regarding the power source, the pressure measuring device PM is operated by, for example, a battery (not shown), and the pressure display device PD is operated by, for example, an AC power source (not shown).

<Operation of the embodiment>
FIG. 7 is a flowchart illustrating the operation of the pressure measurement system according to the embodiment. Hereinafter, the operation of the pressure measurement system of the embodiment will be described with reference to FIG.

  FIG. 8 is a diagram illustrating a state where the measurement subject wears the main unit and shoes. In the following description, prior to measurement, the person to be measured (1) wears any of the main unit MN (PM) shown in FIGS. 4, 5, and (2), and (2) (3) It is assumed that the shoe SH illustrated in FIG.

  FIG. 9 is a diagram showing the pressure applied to the toe of the measurement subject, measured using a foot pressure distribution measurement system “F-SCAN” manufactured by Nitta Corporation. In FIG. 9, a dark part shows that a pressure is strong. With regard to the pressure (load) applied to the toe of the person to be measured who is standing upright while wearing the main unit MN (PM) and the shoe SH, when looking down at FIG. The pressure Pbs applied and the pressure Pk applied to the kite are the highest, and the pressures P1, P2, P3, P4, P5 applied to the first kite, the second kite, the third kite, the fourth kite, and the fifth kite are also large. The value is shown. Moreover, for the pressures P1, P2, P3, P4, and P5, the pressures P1, P2, P3, P4, and P5 are small in the order of the first rod, the second rod, the third rod, the fourth rod, and the fifth rod. It has become.

  Step S1: In FIG. 7, when the power of the pressure measuring device PM is turned on, or the communication unit CM (PM) of the pressure measuring device PM is transferred from the communication unit CM (PD) of the pressure display device PD. When the pressure measurement device PM receives an instruction to measure the pressure applied to the grounding unit, the control unit CT (PM) informs the main unit MN (PM) that the pressure on the toes should be measured. Instruct. Upon receiving the instruction, in the main unit MN (PM), the detection units D1 to D5 receive the first toe, second toe, third toe, fourth toe, and fifth toe of the person being measured from the ground. Measure the pressure.

  Step S2: When the measurement of the pressure applied to the ground contact portion of the toe is completed by the detection units D1 to D5 in Step S1, the control unit CT (PM) sends the measured toe pressure data to the communication unit CM (PM). Instructs that DT should be transmitted to the pressure display device PD. When receiving the instruction, the communication unit CM (PM) transmits the toe pressure data DT to the pressure display device PD. In the present embodiment, the toe pressure data DT is transmitted to the pressure display device PD after the measurement. However, when pressure is measured at every passage of time such as walking, the data is measured at the measured timing (in real time). Can also be sent.

  Step S3: When the toe pressure data DT is transmitted from the communication unit CM (PM) of the pressure measuring device PM in Step S2, the communication unit CM (PD) of the pressure display device PD receives the toe pressure data DT. To do.

  Step S4: When the communication unit CM (PD) receives the toe pressure data DT in step S3, the control unit CT (PD) instructs the display unit DP (PD) to display the toe pressure data DT. To do. Upon receiving the instruction, the display unit DP (PD) displays the pressure applied to the ground contact portion of the toe of the person to be measured, which is determined by the toe pressure data DT.

  FIG. 10 shows the pressure applied to the ground contact portion of the toe, measured by an actual pressure measurement system. As shown in FIG. 10, the display unit DP (PD) of the pressure display device PD is configured such that the pressure applied to the ground contact portion of the toe of the person to be measured is the first heel, the second heel, the third heel, Smallness is displayed in the order of 4 趾 and 5 趾. As shown in FIG. 9, the pressure applied to the toe of the to-be-measured person's toes is smaller in the order of first toe, second toe, third toe, fourth toe, and fifth toe. Is consistent with that. This confirms that the ability to measure toe pressure by the actual pressure measurement system, more precisely the actual body unit, is reliable.

<Effects of the embodiment>
FIG. 11 is a bottom view of the insole of the comparative example. As shown in FIG. 11, the pressure measurement system PMS of the embodiment, more precisely, the bottom surface (surface in contact with the shoe sole) of the insole IS of the comparative example, which is the comparison target of the main body unit MN (PM) of the embodiment, A pressure sensor d1 is provided at a position corresponding to the first heel on the foot of the person to be measured (illustrated by a two-dot chain line), a pressure sensor d2 is provided at a position corresponding to the second heel, and corresponds to the third heel. The pressure sensor d3 is provided at a position where the pressure sensor d3 is provided, and the pressure sensor d4 is provided at a position corresponding to the middle of the fourth and fifth eyelids. Here, the pressure sensors d1 to d4 have performance equivalent to the detection units D1 to D5 of the embodiment.

  FIG. 12 shows the result of measuring toe pressure with the insole of the comparative example. In place of the main unit MN (PM) shown in FIGS. 4, 5, and 6, the pressure applied to the toe of the measured person when the measured person's back wears the insole IS of the comparative example is As shown in FIG. 12, the second heel, the third heel, and the first heel are smaller in order, and this result is completely the same as the order of pressure applied to the toe of the person to be measured shown in FIG. Does not match.

  From the comparison between the measurement result by the actual pressure measurement system and the measurement result by the insole of the comparative example, the main body unit MN (PM) of the embodiment has a toe of the toe of the person to be measured rather than the insole IS of the comparative example It is confirmed that the pressure can be measured with higher accuracy.

As described above, the detection units D1 to D5 of the embodiment are provided at positions corresponding to the positions of the ground contact portions of the toes in the main unit MN (PM). Accordingly, since the amount of the position of the detection units D1 to D5 deviating from the position of the ground contact portion of the toe is reduced compared to a conventional device or the like in which the pressure sensor is arranged on the shoe sole or insole, the foot It is possible to accurately measure the pressure applied to the grounding portion of the finger.
In addition, the body unit MN (PM) of the embodiment can be attached to and detached from the foot, and the shoe SH can be attached to and detached from the foot on which the body unit MN (PM) is attached. In order to measure the pressure applied to the ground contact part of the toes, it is sufficient to attach the main unit MN (PM) and further to wear the shoes SH. The measurement can be made in the procedure.
Furthermore, the main body unit MN (PM) of the embodiment is a small space having a size corresponding to a five-finger socks, that is, unlike a conventional system or the like, it can be measured in a narrow space and a narrow area. In addition, the main unit MN (PM) substantially includes only the detection units D1 to D5 that are pressure sensors or the like, and thus performs the measurement at a lower price than a conventional system or the like. It becomes possible.

  As described above, the convex portions C1 to C5 of the embodiment extend from the position corresponding to the position of the base of the toe in the main body B toward the position corresponding to the position of the tip of the toe. In addition, it is desirable that the detection units D1 to D5 are provided at positions corresponding to the positions of the ground contact portions of the toes in the convex portions C1 to C5. Thereby, since the freedom degree of the position of convex part C1-C5 is restrict | limited by presence of a toe, inevitably the position of the detection part D1-D5 arrange | positioned in each of convex part C1-C5 is carried out. The degree of freedom is also limited, and as a result, the amount of displacement of the positions of the detection parts D1 to D5 from the position of the ground contact part of the toe is further reduced, and as a result, the pressure applied to the ground contact part of the sole of the foot is further increased. It becomes possible to measure accurately.

  As described above, it is desirable that the convex portions C1 to C5 of the embodiment are provided at positions where the convex portions C1 to C5 are in contact with the ground contact portion of the toes. As a result, the detection units D1 to D5 are directly subjected to the pressing force from the ground contact portion of the toe, and as a result, the amount of the detection units D1 to D5 is deviated from the position of the ground contact portion of the toe. Further, since the pressure is further reduced, the pressure applied to the ground contact portion of the toe can be measured more accurately.

  As described above, the convex portions C <b> 1 to C <b> 5 of the embodiment preferably have a shape imitating the shape of a toe and have a size equal to the size of the toe. Thereby, the convex portions C1 to C5 are not easily deformed by the presence of the toes themselves, and as a result, the amount of the positions of the detection units D1 to D5 deviating from the position of the ground contact portion of the toes is further reduced. It becomes possible to measure the pressure applied to the ground contact portion of the toe even more accurately.

  As described above, the convex portions C1 to C5 of the embodiment are pushes that press the base of the foot from the surface of the base of the foot toward the inside of the base of the foot at a position corresponding to the position of the base of each finger of the foot. It is desirable to have pressure. As a result, the convex portions C1 to C5 become more difficult to deform, and as a result, the amount that the positions of the detection portions D1 to D5 deviate from the position of the ground contact portion of the toe is further reduced, It becomes possible to measure the pressure applied to the grounding part of the finger more accurately.

Instead of the above-described detection units D1 to D5 of the main unit MN (PM) measuring the pressure of the toe of the person to be measured once, in order to increase the accuracy of the measurement, the detection units D1 to D1 For example, after D5 is measured twice or more, the control unit CT (PM) or the control unit CT (PD) preferably uses the average value.
Moreover, the pressure measurement system of the present invention can also measure during walking. At that time, the average value calculated from the peak value of the pressure applied to the ground contact portion of each toe may be evaluated, and the operations of steps S1 to S4 may be performed in the same manner.

<Evaluation of floating finger>
FIG. 13 is a flowchart illustrating an operation for evaluating a floating finger. Hereinafter, with reference to FIG. 13, the operation | movement which evaluates a floating finger by the pressure measurement system of embodiment is demonstrated.

  Step S10: The pressure of the toe of another person (hereinafter referred to as “measured person B”) who receives the measurement of the pressure applied to the toe is measured in the same manner as in steps S1 to S3 described above. The toe pressure data DT of the measurement subject B reaches the control unit CT (PD) of the pressure display device PD, which is measured by the main unit MN (PM) of the device PM.

  FIG. 14 is a diagram illustrating a result of measuring the pressure of the toe of the measurement subject. The pressure of the toe of the measurement subject B is as shown in “Before wearing the floating finger reduction insole” (left bar graph) in FIG.

  Step S <b> 11: The control unit CT (PD) stores the toe pressure data DT (“before wearing the floating finger reducing insole” in FIG. 14) stored in the ROM 60 and a predetermined threshold TH. (For example, threshold TH determined from weight, height, sex, age, foot size, etc.). Here, in the control unit CT (PD), when the first rod, the second rod, and the third rod of the person to be measured are each smaller than the threshold value TH, the first rod, the second rod, and the third rod are floated. Judgment is likely to be a finger.

  FIG. 15 is a diagram illustrating an insole for reducing floating fingers.

Step S12: The to-be-measured person B puts a floating finger by himself or by a company having a pressure measurement system PMS (for example, a shoe store, a shoe manufacturer, a shoe repair shop, a department store) as shown in FIG. An insole IS (F) for reduction, that is, an insole for floating finger reduction (IS (F)) is prepared. As the floating finger reducing insole (IS (F)), the one shown in FIG. 15 disclosed in Japanese Patent No. 5134072 is preferable. Specifically, the floating finger reducing insole (IS (F)) includes a base material portion 100 and an elastic portion 200.
In the region between the second heel and the third heel, the elastic portion 200 tries to use the foot heel, particularly the first heel and the second heel, by setting the position beyond the joint between the midfoot and heel joints as the periphery. In the region between the third heel and the fourth heel, the elastic part 200 tries to use the foot heel, particularly the third heel and the fourth heel, by setting the position corresponding to the position in front of the metatarsal head as a peripheral edge. To do. Accordingly, the floating finger reducing insole (IS (F)) promotes the use of the toes, and as a result, the floating fingers can be reduced.

  Step S12: Similar to the above-described steps S1 to S3, in other words, the main unit MN (PM) of the pressure measuring device PM is now the floating finger reducing insole IS (F), similar to the above-described step S11. The pressure of the toe of the person to be measured who wears the toe is measured, and the measured toe pressure data DT reaches the control unit CT (PD) of the pressure display device PD. Here, the toe pressure data DT measured in step S12 is as shown in “After wearing the floating finger reducing insole” (right bar graph) in FIG.

  Step S13: The control unit CT (PD) displays the toe pressure data DT (before wearing the floating finger reducing insole) and the toe pressure data DT (wearing the floating finger reducing insole) on the display unit DP (PD). After that, the display unit DP (PD) displays the toe pressure data DT (before wearing the floating finger reduction insole) and the toe pressure data DT (floating finger reduction). (After wearing the insole) is displayed as shown in FIG.

  Step S14: The to-be-measured person B is toe pressure data DT shown in FIG. 14 by himself or by a company having a pressure measurement system PMS (for example, a shoe store, a shoe manufacturer, a shoe repair shop, a department store). By comparing the toe pressure data DT (after wearing the floating finger reduction insole) (after wearing the floating finger reduction insole), the first toe, second toe, and third toe of the person to be measured Check if the level of the floating finger is reduced.

  Here, in FIG. 14, the load of the first toe, the second toe, and the third toe of the person to be measured, that is, the pressure, the insole for reducing the floating finger is compared with the insole for reducing the floating finger. Since the one after wearing is larger, it can be said that the first leg, the second leg, and the third leg of the person being measured were reduced.

  By using the pressure measurement system PMS of the embodiment, it can be determined whether or not the toe of the person to be measured is a floating finger, and a finger that is highly likely to be a floating finger is reduced in floating finger It can also be confirmed whether it was reduced by wearing for insole IS (F).

  Moreover, if the pressure measurement system PMS of this invention is used, it will become possible to evaluate whether a floating finger can be reduced by the difference in shoes other than an insole. Note that the pressure measurement system PMS of the present invention can be used for purposes other than evaluation of floating fingers.

<Application example>
In the pressure measurement system PMS of the embodiment, instead of or in addition to measuring the pressures of the first to fifth rods by the detectors D1 to D5, other detectors (detector D1) Measures the pressure in the vicinity of the main ball, the small ball, the heel, and the second and third metatarsals, which are most important on the sole of the foot from the viewpoint of load. By doing this, it is possible to grasp the distribution of the load applied to both the left and right feet, and further, it is possible to grasp the timing of landing during walking, etc. by continuing the measurement over time is there.

  In addition to measuring the first to fifth pressures by the detection units D1 to D5, the pressure measurement system PMS of the embodiment includes other sensors (for example, a gyro sensor, an acceleration sensor, and an atmospheric pressure sensor), By measuring the situation of other parts of the body, for example, it is possible to grasp the walking state, running state, jumping state, etc. (including walking, running state, jumping speed).
