Description

[Technical Field]

[0001] The present invention relates to an insole presentation system and an insole presentation method. [Background technology]

[0002] Conventionally, when walking or running in shoes, an insole is inserted into the sole of the shoe to improve the fit between the shoe and the foot and to absorb shock. It has also been proposed to acquire information on the shape of the foot and information on the movement of the foot during walking and to create insoles suited to the different foot shapes and walking movements of each individual (see, for example, Patent Documents 1 to 3).

[0003] The prior art techniques shown in Patent Documents 1 to 3 allow for the creation of custom-made or semi-custom-made insoles shaped to suit each individual, thereby reducing the impact on the feet when walking and correcting posture to ensure proper walking. This is thought to prevent injuries and diseases to the joints and muscles caused by the stress of walking or running. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2007-526028 [Patent Document 2] Special Publication No. 2017-522917 [Patent Document 3] Japanese Patent Publication No. 2022-089563 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the technologies disclosed in Patent Documents 1 and 2, a dedicated pressure sensor device is attached to measure the distribution of load on the sole of the foot. Such pressure sensor devices require specialized knowledge and proficiency in operation, including how to attach them, how to measure them, and how to maintain them, which poses a problem in that it is difficult for individual users or sales staff with little specialized knowledge to form insoles appropriately.

[0006] Furthermore, the technology disclosed in Patent Document 3 acquires data from various movements as comprehensive movement data or pentagonal movement data, and determines the convex shape of the insole near the big toe so as to correct the movement trajectory of the Center of Pressure (COP). However, the amount of data required is enormous, and it is necessary to acquire the data by performing multiple complex movements, which poses the problem of making it difficult to form the insole easily.

[0007] Furthermore, Patent Documents 1 to 3 aim to distribute the load on the sole of the foot using an insole shape, not to improve actual walking motion. Furthermore, even if the load on the sole of the foot is distributed using an insole shape, it is difficult to sufficiently improve walking motion, which occurs due to the intertwining of complex factors, or to sufficiently reduce the load on the body.

[0008] Therefore, the present invention has been made in consideration of the above-mentioned conventional problems, and aims to provide an insole presentation system and an insole presentation method that can easily obtain the necessary data through simple measurements and does not require specialized knowledge about measurements or mastery of device operation. [Means for solving the problem]

[0023] (First embodiment) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or equivalent components, parts, and processes shown in each drawing will be denoted by the same reference numerals, and redundant descriptions will be omitted where appropriate. FIG. 1 is a schematic diagram illustrating an overview of an insole presentation system 1000 according to this embodiment. As shown in FIG. 1, the insole presentation system 1000 includes an information acquisition device 100, an insole presentation device 200, and an insole selection device 300. Each device realizes various functions by executing a predetermined program on a computer equipped with a memory unit, an input unit, an output unit, a calculation unit, an information communication unit, etc., and is capable of mutual information communication. While FIG. 1 illustrates an example in which each device is configured with separate hardware and communicates information with each other via electrical information communication lines, multiple programs running on the same hardware configuration may function as each device. Alternatively, multiple functions may be realized on separate hardware configurations and function as each device in cooperation with each other.

[0024] The information acquisition device 100 is a device for acquiring information necessary for selecting an insole and transmitting the information to the insole selection device 300. In the example shown in FIG. 1, the information acquisition device 100 includes an attribute information acquisition unit 110, a foot shape data acquisition unit 120, and a foot movement data acquisition unit 130. Various pieces of information acquired by the information acquisition device 100 are transmitted to the insole selection device 300 by an information communication means via an electric information communication line or the like. The specific configuration of the information acquisition device 100 is not limited, and may be an information processing device such as a personal computer or a smartphone, or may be configured such that multiple devices are connected to each other so as to be able to communicate information with each other.

[0025] The attribute information acquisition unit 110 is a part that acquires attribute information about the insole user. The specific configuration of the attribute information acquisition unit 110 is not limited, and the attribute information acquisition unit 110 may be configured to input information into an input form displayed on a screen using an input device of an information processing device such as a personal computer or a smartphone. Also, separately recorded information about the user may be acquired by an information communication means. Here, the attribute information about the user may include age, sex, height, weight, medical history, exercise history, exercise habits, and exercise type.

[0026] The foot shape data acquisition unit 120 is a part that acquires foot shape data, which is information regarding the shape of the foot of an insole user. The specific configuration of the foot shape data acquisition unit 120 is not limited, and the foot shape data may be measured by capturing a foot shape using a plaster cast or the like and input using an information processing device. A conventionally known dedicated device for measuring foot shape data may also be used. A three-dimensional image of the foot may be captured using an imaging device or LiDAR (Light Detection and Ranging) device mounted on a smartphone or tablet, and foot shape data may be acquired using image recognition technology or three-dimensional measurement technology. Examples of foot shape data include the length from heel to toe, width, instep height, and ground contact surface shape. The foot shape data may be acquired with the foot on the ground in a weight-bearing state, or with the foot lifted from the ground in a non-weight-bearing state.

[0027] The foot movement data acquisition unit 130 is a part that acquires foot movement data, which is information about foot movement, during the period when the insole user's feet are moving (foot movement period) while walking or running. The specific configuration of the foot movement data acquisition unit 130 is not limited, and a method of detecting trajectory and tilt by installing an acceleration sensor and a gyro sensor in the shoes used during the test walking can be used. As an example, Senno Gait (registered trademark) manufactured by Sennotech can be used. Alternatively, foot movement data can be acquired by capturing video of the foot movement using an imaging device or LiDAR device installed in a smartphone or tablet, and using motion capture technology or image recognition technology.

[0028] Here, examples of foot movement data include the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion (pronation) and eversion (supination) of the ankle joint, the degree of adduction and abduction of the ankle joint, stride length, foot trajectory, foot lift height, foot swing speed, widthwise distance between the feet, etc. In this embodiment, as will be described later, the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of adduction and abduction of the ankle joint during the foot movement period are important as foot movement data.

[0029] The insole presentation device 200 is a device that receives information selected by the insole selection device 300 and presents it to the user. In the example shown in FIG. 1, the insole presentation device 200 includes an insole presentation unit 210 and a recommended exercise presentation unit 220. The insole presentation device 200 receives information about the insole selected by the insole selection device 300 and recommended exercise information from the insole selection device 300 via an electric information communication line or the like using information communication means, and presents the information to the user. The specific configuration of the insole presentation device 200 is not limited, and various information processing devices such as a computer or a smartphone can be used. In addition, known information output means such as an image display device, an audio guidance device, or a paper printing device can be used as a method of presenting information.

[0030] The insole presenting unit 210 is a device that receives information on insoles suitable for the insole user selected by the insole selecting device 300 and presents it to the insole user. The insole presenting unit 210 may also be provided with an online ordering means or the like, and may be provided with a function to access an online store connected via an electric information communication line and order the presented insole online. The insole information presented by the insole presenting unit 210 will be described in detail later.

[0031] The recommended exercise presenting unit 220 is a device that receives recommended exercise information associated with the insole selected by the insole selecting device 300 and presents it to the insole user. The recommended exercise presenting unit 220 may also transfer the recommended exercise information to another device such as an exercise aid and use it to control or adjust the operation of the exercise aid. In this embodiment, an example is shown in which the recommended exercise presenting unit 220 is provided in the insole presenting device 200, but the recommended exercise presenting unit 220 may be omitted. The recommended exercise information presented by the recommended exercise presenting unit 220 will be described in detail below.

[0032] The insole selection device 300 is a device that selects an insole suitable for an insole user based on information received from the information acquisition device 100 and transmits the selected insole to the insole presentation device 200. In the example shown in FIG. 1, the insole selection device 300 includes an attribute information database 310, a foot shape database 320, a foot movement database 330, an insole database 340, a recommended exercise database 350, an insole selection unit 360, and a recommended exercise selection unit 370. The specific configuration of the insole selection device 300 is not limited, and a server device equipped with a storage means, an information processing means, and an information communication means can be used. Although FIG. 1 shows an example in which the insole selection device 300 is configured as a device separate from the information acquisition device 100 and the insole presentation device 200, it may also be configured as the same hardware as these devices.

[0033] The attribute information database 310 is a section that records the attribute information of the insole user acquired by the attribute information acquisition unit 110. The attribute information about the user recorded in the attribute information database 310 is recorded in association with an identification number assigned to each user. The identification number is also associated with the footprint data recorded in the footprint database 320 and the foot movement data recorded in the foot movement database 330.

[0034] The footprint database 320 is a part that records footprint data acquired by the attribute information acquisition unit 110. The footprint data recorded in the footprint database 320 is recorded in association with an identification number assigned to each user in the attribute information database 310.

[0035] The foot movement database 330 is a part that records the foot movement data acquired by the attribute information acquisition unit 110. The foot movement data recorded in the foot movement database 330 is recorded in association with an identification number assigned to each user in the attribute information database 310.

[0036] The insole database 340 is a section that records information about the insoles selected by the insole selection section 360. The insole information recorded in the insole selection section 360 includes information about the shape, size, thickness, position, effect, etc. of the base insole 10 and the reinforcing insoles 11 to 17, as will be described in detail later.

[0037] The recommended exercise database 350 is a section that records recommended exercise information selected by the recommended exercise selection unit 370. The recommended exercise information recorded in the recommended exercise database 350 includes information on myofascial release methods, gait improvement methods, training methods, massage methods, rehabilitation methods, etc., as will be described in detail below.

[0038] The insole selection unit 360 is a part that selects appropriate insole information from the insole database 340 based on the foot movement data acquired by the foot movement data acquisition unit 130, and transmits the information to the insole presentation device 200. The insole selection unit 360 may also use attribute information and foot shape data associated with the same identification number.

[0039] The recommended exercise selection unit 370 is a part that selects appropriate recommended exercise information from the recommended exercise database 350 based on the information of the insole selected by the insole selection unit 360, and transmits the information to the insole presentation device 200. The recommended exercise selection unit 370 may also use attribute information and foot shape data associated with the same identification number to select recommended exercises.

[0040] 2A and 2B are diagrams showing examples of databases in the insole presentation system 1000, with Fig. 2A showing an example of the insole database 340 and Fig. 2B showing an example of the recommended exercise database 350. The examples shown in Fig. 2 are examples of the insole database 340 and the recommended exercise database 350, and each may include more items or more subdivided information.

[0041] The insole information recorded in the insole database 340 includes information on the base insole 10, which covers the entire sole of the foot, and information on the reinforcing insoles 11-17, which are placed at predetermined positions on the base insole 10. The information on the base insole 10 also includes items such as shape, material, and thickness. The information on the reinforcing insoles 11-17 also includes multiple parts (e.g., parts A, B, C, etc.) and items such as shape, material, and thickness for each part. The information on the base insole 10 and the reinforcing insoles 11-17 may further include many items or subdivided information such as size, characteristics, and effects.

[0042] The recommended exercise information recorded in the recommended exercise database 350 includes multiple pieces of information on the parts to be worked and the exercise characteristics. In addition, recommended exercises are associated with the information on each part to be worked. In addition, recommended exercises are associated with the information on each exercise characteristic. Recommended exercises include myofascial release methods, gait improvement methods, training methods, etc.

[0043] Myofascial release methods include massage and stretching methods to promote fascial stretching and range of motion in specific body parts. Methods for improving gait include how to use the toes, how to move the pelvis, head position, walking posture, and shifting the center of gravity on the soles of the feet. Training methods include exercises to strengthen muscles in specific body parts, stretching methods to increase the range of motion in specific body parts, and movement practice required for sports.

[0044] FIG. 3 is a diagram schematically illustrating an example of an insole presented by the insole presentation system 1000, where FIG. 3(a) shows the base insole 10 and FIG. 3(b) shows the reinforcing insoles 11-17. The base insole 10 has an outer shape that covers the entire sole of the foot and is inserted into the sole of the shoe to come into contact with the sole of the insole user. The reinforcing insoles 11-17 are attached to the back side (the side facing the ground opposite the sole of the user) of the base insole 10 at predetermined positions. There are no particular limitations on the method for attaching the base insole 10 and the reinforcing insoles 11-17. For example, the base insole 10 and the reinforcing insoles 11-17 may be made of a thermoplastic resin and then heated and pressed together. Alternatively, an adhesive may be applied between the base insole 10 and the reinforcing insoles 11-17 to bond them together. By attaching the selected reinforcing insoles 11-17 to the back side of the base insole 10, an insole suitable for the insole user can be formed. Further, although an example in which the reinforcing insoles 11 to 17 are attached to the rear surface of the base insole 10 has been shown here, they may be attached to the bottom surface of the base insole 10.

[0045] As shown in Figure 3(a), the base insole 10 has an outer shape that covers the entire sole of the foot. Here, the entire sole preferably includes not only the area that the sole of the foot actually comes into contact with when the insole is inserted into the shoe, but also the area of ​​the plantar arch that the sole does not come into contact with. By providing the base insole 10 including the plantar arch area, the reinforcing insoles 11-17 can be attached and held in place effectively. Furthermore, the strength and elasticity of the base insole 10 alone can be ensured.

[0046] As shown in Fig. 3(b), the reinforcing insoles 11 to 17 are attached to predetermined positions on the base insole 10. Fig. 3(b) shows the state in which all of the reinforcing insoles 11 to 17 are attached, but in an actual insole, parts selected from the reinforcing insoles 11 to 17 by the insole selection unit 360 are attached.

[0047] The reinforced insoles 11 to 17 shown in FIG. 3(b) are merely examples, and specific examples will be described below. The reinforced insole 11 is positioned and shaped to cover the medial side of the calcaneus and the talus. The reinforced insole 12 is positioned and shaped to cover the lateral side of the calcaneus and the lateral side of the cuboid. The reinforced insole 13 is positioned and shaped to cover a wide area of ​​the plantar arch. The reinforced insole 14 is positioned and shaped to cover a narrow area of ​​the plantar arch. The reinforced insole 15 is positioned and shaped to fit along the middle phalanges of the big toe to the little toe. The reinforced insole 16 is positioned and shaped to cover the ball of the foot. The reinforced insole 17 is positioned and shaped to cover the sesamoid, proximal phalanges, middle phalanges, and distal phalanges of the big toe. The shapes and positions of the reinforced insoles 11 to 17 shown in FIG. 3(b) are merely examples, and the insoles may include multiple parts, or multiple parts may be connected together to form a single unit.

[0048] As shown in Figure 3(b), the reinforcing insoles 11 to 17 are attached to the base insole 10 at predetermined positions, but they may also be attached to overlapping positions, such as the combination of reinforcing insoles 13 and 14 or the combination of reinforcing insoles 15, 16, and 17. Also, multiple pieces of each of the reinforcing insoles 11 to 17 may be stacked on top of each other. By stacking the reinforcing insoles 11 to 17, the desired thickness and strength can be easily achieved.

[0049] Figure 4 is a diagram showing the degree of plantarflexion and dorsiflexion of the ankle joint included in the foot movement data, with Figure 4(a) showing the angle at landing and Figure 4(b) showing the angle at push-off. In the diagram, the plane parallel to the contact surface is shown with a thick solid line, the ankle and toes are shown schematically, and the insole inserted into the sole is shown as a white plate. The direction perpendicular to the ground and the direction perpendicular to the insole are shown with dashed lines, respectively.

[0050] As shown in FIG. 4(a), when walking or running, the foot lands on the ground first, with the heel of the foot moved forward, and the sole of the foot then touches the ground in order toward the toes. At this time, body weight is applied to the sole, and the center of load moves forward within the plane of the sole. The angle between the direction perpendicular to the sole (insole) and the direction perpendicular to the ground surface during the movement of the foot is defined as θ1. The angle between the sole and the ground surface during the movement of the foot is defined as θ2. In this embodiment, the angles θ1 and θ2 between the heel and the ground surface during the movement of the foot are included in the foot movement data. Therefore, the foot movement data includes the degree of plantar flexion and dorsiflexion of the ankle joint, which can be calculated from the angles θ1 and θ2.

[0051] As shown in FIG. 4(b), when pushing off during walking or running, the foot remaining behind gradually leaves the ground surface from the heel to the toe. At this time, the body weight is also applied to the sole of the foot, and the center of load moves forward within the plane of the sole. The angle between the direction perpendicular to the sole of the foot and the direction perpendicular to the ground surface during the movement of the foot is defined as θ3. The angle between the sole of the foot and the ground surface during the movement of the foot is defined as θ4. In this embodiment, the angles θ3 and θ4 between the toe and the ground surface during the movement of the foot are included in the foot movement data. Therefore, the foot movement data includes the degree of plantar flexion and dorsiflexion of the ankle joint, which can be calculated from the angles θ3 and θ4.

[0052] FIG. 5 is a diagram schematically illustrating foot trajectories included in foot movement data. The four footprints shown in the figure indicate the ground contact positions of the right and left feet when the insole user is walking or running. The trajectory of the right foot's movement in the air is indicated by a solid curve TR, and the trajectory of the left foot's movement in the air is indicated by a solid curve TL. The curves TR and TL, which are actual foot trajectories, depict three-dimensional trajectories because the foot remaining on the ground surface behind is raised, the foot moves forward, reaches its highest point, and the forward foot touches the ground. The ground contact distance between the left and right feet when the right foot is forward is designated DR, and the ground contact distance between the left and right feet when the left foot is forward is designated DL. The ground contact distance in the width direction of the left and right feet is designated W. In this embodiment, the foot movement data includes the curves TR and TL, which are the foot trajectories when walking or running, the ground contact distances DR and DL in the front-to-back direction of the left and right feet, and the ground contact distance W in the width direction of the left and right feet.

[0053] Figure 6 is a diagram showing the foot orientations included in the foot movement data, where Figure 6(a) shows pronation, Figure 6(b) shows supination, Figure 6(c) shows abduction, and Figure 6(d) shows adduction.

[0054] Figures 6(a) and (b) are diagrams of the left and right feet viewed from the heel side, and the thick solid lines in the diagram indicate the talocrural joint, the direction of extension of the tibia, the direction of extension of the calcaneus, and the underside of the heel. Figure 6(a) shows the calcaneus extending downward from the talocrural joint opening outward and pronating (inward). Figure 6(b) shows the calcaneus extending downward from the talocrural joint closing inward and supinating (outward).

[0055] Figures 6(c) and 6(d) show the orientation of the soles of the left and right feet, and the solid lines in the figures indicate the direction extending from the heel to the center of the toes. Figure 6(c) shows a state in which the direction from the heel to the toes is turned outward and abducted. Figure 6(d) shows a state in which the direction from the heel to the toes is turned inward and adduction. In this embodiment, the degree of inversion / eversion of the ankle joint and the degree of abduction / inversion of the ankle joint are included in the foot movement data.

[0056] Fig. 7 is a flowchart showing an example of the operation of the insole presentation method using the insole presentation system 1000. As shown in Fig. 7, the insole presentation method of this embodiment includes an attribute information acquisition step, a foot shape data acquisition step, a foot movement data acquisition step, an insole selection step, an insole presentation step, a recommended exercise selection step, and a recommended exercise presentation step. In this embodiment, it is assumed that insole information is recorded in advance in the insole database 340, and recommended exercise information is recorded in the recommended exercise database 350.

[0057] First, in the attribute information acquisition step of step S1, attribute information of an insole user is acquired using the attribute information acquisition unit 110. As an example, the insole user inputs the attribute information using an input means such as a mobile information terminal. The attribute information acquisition unit 110 accesses the insole selection device 300 via an electric information communication line or the like, and records the acquired attribute information in the attribute information database 310 in association with an identification number. Furthermore, if the insole user is using the insole presentation system 1000 for the second time or later, the attribute information acquisition unit 110 may access the insole selection device 300 via an electric information communication line or the like, and read the attribute information from the attribute information database 310. Here, an example is shown in which the insole user operates the attribute information acquisition unit 110 himself / herself, but the information acquisition device 100 may also be operated by a salesperson or counselor at an insole retailer.

[0058] Next, in the foot print data acquisition process of step S2, the foot print data of the insole user is acquired using the foot print data acquisition unit 120. As an example, the insole user inputs foot print data measured using a tape measure or the like using an input means such as a portable information terminal. The foot print data acquisition unit 120 accesses the insole selection device 300 via an electric information communication line or the like, associates the acquired attribute information with an identification number, and records it in the foot print database 320. Furthermore, if the insole user is using the insole presentation system 1000 for the second time or later, the foot print data acquisition unit 120 may access the insole selection device 300 via an electric information communication line or the like, and read the foot print data from the foot print database 320. Here, an example is shown in which the insole user inputs the foot print data himself / herself, but the foot print data acquisition unit 120 may also be operated by a salesperson or counselor at an insole retailer.

[0059] Next, in the foot movement data acquisition process of step S3, the foot movement data acquisition unit 130 is used to acquire foot movement data of the insole user. As an example, a measurement device incorporating an acceleration sensor, a gyro sensor, and near-field communication, etc., is used. The insole user wears the shoes with the measurement device inserted into the sole and walks or runs. The measurement device acquires information such as the orientation, movement distance, and angle of the sole over time and transmits it to the information acquisition device 100 via near-field communication, etc. The foot movement data acquisition unit 130 accesses the insole selection device 300 via an electrical information communication line, etc., and records the acquired foot movement data in the foot movement database 330 in association with an identification number. The measurement by the foot movement data acquisition unit 130 may be performed by the insole user themselves, or by a salesperson or consultant at an insole retailer.

[0060] Next, in the insole selection process of step S4, the insole selection unit 360 selects an appropriate base insole 10 from the insole database 340 based on the attribute information, foot shape data, and foot movement data associated with the identification number, and selects an appropriate combination from the reinforced insoles 11 to 17. As an example, the insole selection unit 360 stores the degree of association between the attribute information, foot shape data, and foot movement data for the base insole 10 and the reinforced insoles 11 to 17 in a matrix. The insole selection unit 360 selects the base insole 10 and the reinforced insoles 11 to 17 with the highest degree of association from the attribute information, foot shape data, and foot movement data from the matrix. The insole selection unit 360 transmits information about the selected base insole 10 and the reinforced insoles 11 to 17 as insole information to the insole presentation unit 210 via an electrical information communication line. The insole selection unit 360 may also associate the insole information with the identification number and record it in the attribute information database 310.

[0061] Next, in the insole presentation process of step S5, the insole presentation unit 210 receives the insole information from the insole selection unit 360 and presents information about the selected insole to the operator of the insole presentation device 200. The operator of the insole presentation device 200 may be the insole user himself / herself, or a salesperson or counselor at an insole retailer. As an example, the shape, material, and thickness of the combination of the selected base insole 10 and the selected reinforced insole 11-17 are displayed on an image display device. The combination of the selected base insole 10 and the reinforced insole 11-17 may be displayed as a three-dimensional model on the image display device. Furthermore, instead of displaying the shape, material, and thickness, the model numbers of the selected base insole 10 and the reinforced insole 11-17 may be displayed.

[0062] Next, in step S6, a recommended exercise selection process, the recommended exercise selection unit 370 selects appropriate recommended exercise information from the recommended exercise database 350 based on the insole information selected by the insole selection unit 360. When selecting recommended exercise information, the recommended exercise selection unit 370 may also refer to attribute information, foot shape data, and foot movement data associated with the identification number. As an example, the recommended exercise selection unit 370 stores a matrix of associations between the base insole 10 and the reinforced insoles 11-17 and the recommended exercise information. The recommended exercise selection unit 370 selects the recommended exercise information with the highest association from the selected insole information using the matrix. The recommended exercise selection unit 370 transmits the selected recommended exercise information to the recommended exercise presentation unit 220 via an electrical information communication line. The recommended exercise selection unit 370 may also associate the recommended exercise information with the identification number and record it in the attribute information database 310.

[0063] Next, in the recommended exercise presentation process of step S7, the recommended exercise presentation unit 220 receives the recommended exercise information from the recommended exercise selection unit 370 and presents the selected recommended exercise information to the operator of the insole presentation device 200. The operator of the insole presentation device 200 may be the insole user himself / herself, or a salesperson or counselor at an insole retailer. As an example, the recommended exercise method, the equipment to be used, the fascia release method, etc. may be displayed on an image display device. Furthermore, the actual movements of the recommended exercise may be displayed as a video. After the recommended exercise presentation process is completed, the insole presentation method of this embodiment ends.

[0064] As an example of the insole suggestion method described above, a case will be described in which the foot shape data indicates hallux valgus on the right foot only, and the foot movement data indicates a small degree of plantar flexion and dorsiflexion at the ankle joint, resulting in inversion of the ankle joint. In the insole selection process, the shape of the heel cup of the base insole 10 is determined to match the shape of the heel so as to promote plantar flexion and dorsiflexion at the ankle joint and prevent inversion. Furthermore, since weight is applied to the right foot with hallux valgus, reinforced insoles 11 and 12 are added to the heel of the left foot. Furthermore, reinforced insoles 13 and 14 are added to raise the medial arch to relieve load on the first metatarsal head. A reinforced insole 16 is added to activate mechanoreceptors so that the ball of the foot can be firmly pressed and kicked off the ground.

[0065] In the recommended exercise presentation, we suggest releasing the posterior tibialis muscle's fascia using oil and tools specifically designed for fascia release, since the posterior tibialis muscle's function is impaired. Furthermore, we suggest releasing the fascia of the sole of the foot using specialized tools, since the fascia of the entire sole of the foot is stiff. We also present and instruct basic ankle and hip joint usage and walking techniques to effectively use insoles. By performing these recommended exercises, it becomes easier to plantarflex and dorsiflex the ankle joint, and to distribute weight across the entire sole of the foot.

[0066] As described above, the insole information, which is a combination of the base insole 10 and the reinforcing insoles 11 to 17, is selected based on the foot movement data, so that necessary data can be easily obtained by simple measurement. Furthermore, specialized knowledge about the measurement and mastery of device operation are not required.

[0067] The foot movement data preferably includes any one of the following: the degree of plantar flexion / dorsiflexion of the ankle joint, the degree of inversion / eversion of the ankle joint, and the degree of adduction / abduction of the ankle joint. More preferably, the foot movement data combines two of the degree of plantar flexion / dorsiflexion of the ankle joint, the degree of inversion / eversion of the ankle joint, and the degree of adduction / abduction of the ankle joint, and even more preferably combines all of them.

[0068] The inventors of the present application have discovered that selecting the base insole 10 and the reinforced insoles 11-17 based on foot movement data is important from the perspectives of reducing the burden on the body when walking or running, preventing falls while walking or running, and assisting recovery from a state of difficulty walking to walking on one's own. In particular, the inventors have discovered that the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of eversion and inversion of the ankle joint, and the degree of abduction and inversion of the ankle joint are important in order to easily and quickly obtain the information necessary for selecting an insole. Furthermore, the inventors have discovered that the time of landing, in particular, is extremely important during the foot movement period during which foot movement data is measured.

[0069] When walking or running, the foot repeatedly moves and the load is transferred as shown in Figure 5, but the load on the foot moves from the heel to the toes when the foot lands. Furthermore, the impact on the foot when walking or running is first felt by the heel and is greatest. Furthermore, the final point in the foot's trajectory when walking or running is the point at which the foot lands, and the angle of the heel at the time of landing varies depending on the way the foot moves. Therefore, in order to select the optimal insole to reduce the burden on the body and promote appropriate foot movement, the degree of plantar flexion and dorsiflexion of the ankle joint is an important part of foot movement data.

[0070] In addition, the path of weight transfer from the heel to the toes differs depending on the degree of inversion / eversion of the ankle joint when landing. Furthermore, when weight transfers after landing, the weight is applied from the fibula and tibia to the talocrural joint and calcaneus, so the degree of inversion / eversion of the ankle joint affects the strain on the talocrural joint, knee joint, hip joint, etc. Therefore, the degree of inversion / eversion of the ankle joint is also very important when selecting the optimal insole to reduce strain on the body and promote proper foot movement.

[0071] In addition, the path of load transfer from the heel to the toes differs depending on the degree of ankle abduction / inversion at the time of landing. Furthermore, when load transfers after landing, the force exerted when the rear foot strikes the ground is transmitted from the sole of the foot to the fibula, tibia, talocrural joint, and calcaneus. Therefore, the degree of ankle abduction / inversion affects the strain on the talocrural joint, knee joint, hip joint, etc. Therefore, the degree of ankle abduction / inversion is also extremely important when selecting the optimal insole to reduce strain on the body and promote proper foot movement.

[0072] In addition, the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and adduction of the ankle joint can be obtained simply by measuring the angle of the sole of the foot, making measurements simple and quick. Furthermore, even without directly measuring the load transfer on the sole of the foot, a combination of the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and adduction of the ankle joint can be used to estimate the load transfer or to substitute for load transfer data. This makes it possible to simply and quickly select a combination of an appropriate base insole 10 and an appropriate reinforcing insole 11-17.

[0073] Furthermore, by including stride length, foot trajectory, foot lift height, foot swing speed, and widthwise distance between the feet in the foot movement data, and further referring to this data, it is possible to select an insole with even greater precision.

[0074] Furthermore, by presenting recommended exercise information associated with the insole using the recommended exercise presentation unit 220, it is possible to advise the insole user on exercises suitable for walking or running. This not only assists walking or running through the combination of the base insole 10 and the reinforced insoles 11 to 17, but also encourages the insole user to adopt a walking posture and method that is less likely to cause falls and that reduces the burden on the joints, thereby helping to prevent injuries and illnesses.

[0075] Furthermore, by including fascia release methods, walking improvement methods, and training methods in the recommended exercise information, it is possible to provide appropriate rehabilitation information to elderly people and people with walking difficulties, and to provide information useful for preventing injury and improving athletic performance to athletes of specific sports.

[0076] In addition, the attribute information acquisition unit 110 acquires attribute information about the insole user, and when the insole selection unit 360 selects a combination of the base insole 10 and the reinforcing insoles 11 to 17, the attribute information is also used, thereby taking into account the attributes of the insole user and allowing for the selection and presentation of more appropriate insoles.

[0077] In addition, by acquiring foot shape data using the foot shape data acquisition unit 120 and using the foot shape data when the insole selection unit 360 selects a combination of the base insole 10 and the reinforcing insoles 11 to 17, it is possible to select and present a more appropriate insole taking into account the foot shape of the insole user.

[0078] As described above, in the insole presentation system 1000 and the insole presentation method of this embodiment, the insole information, which is a combination of the base insole 10 and the reinforced insoles 11 to 17, is selected based on the foot movement data, so that necessary data can be easily obtained by simple measurement. Furthermore, specialized knowledge about measurement and mastery of device operation are not required.

[0079] (Second embodiment) Next, a second embodiment of the present invention will be described. Descriptions of content that overlaps with the first embodiment will be omitted. In the first embodiment, an example was shown in which the insole selection unit 360 selected a combination of the base insole 10 and the reinforcing insoles 11 to 17 based on the degree of association between the attribute information, foot shape data, and foot movement data recorded in the matrix, but in this embodiment, the selection is based on a predetermined relationship.

[0080] As one example, foot movement data serving as a target value is recorded in advance in the insole selection unit 360 as target data, and the difference between the foot movement data of the insole user and the target data is calculated, and a combination of the base insole 10 and the reinforcing insoles 11-17 is selected based on the difference. As a more specific example, if the target data for the degree of plantar flexion and dorsiflexion of the ankle joint is X degrees and the degree of plantar flexion and dorsiflexion of the ankle joint acquired by the foot movement data acquisition unit 130 is Y degrees, the combination of the base insole 10 and the reinforcing insoles 11-17 is selected based on the difference (XY) degrees. Similarly, for the degree of ankle inversion / eversion and the degree of ankle abduction / abduction, the difference between the target data and the measured value is calculated and used for insole selection. Also, instead of recording target data in advance, the average value of the foot movement data measurement results of multiple insole users may be used as the target data.

[0081] (Third embodiment) Next, a third embodiment of the present invention will be described. Descriptions of content that overlaps with the first and second embodiments will be omitted. In this embodiment, the attribute information acquisition unit 110 acquires health condition history information, which is the current health condition, and records the identification number and the health condition history information in association with each other in the attribute information database 310.

[0082] Attribute information, foot shape data, foot movement data, information on the presented insoles, and information on the presented recommended exercises are recorded in association with the identification number in attribute information database 310. Therefore, by recording health condition history information in attribute information database 310, it becomes possible to analyze the use of insoles and recommended exercises and the history of health condition.

[0083] The insole selection unit 360 and the recommended exercise selection unit 370 use machine learning to analyze the relationships between the attribute information, foot shape data, foot movement data, presented insole information, presented recommended exercise information, and health condition history information recorded in the attribute information database 310, and can refer to the analysis results obtained by this machine learning when selecting a combination of the base insole 10 and the reinforcing insoles 11 to 17 from the next time onwards. This makes it possible to further enhance the effects of using insoles and recommended exercises, such as preventing injuries and illnesses and preventing decline in athletic ability.

[0084] (Fourth embodiment) Next, a fourth embodiment of the present invention will be described. Descriptions of content overlapping with the first to third embodiments will be omitted. In this embodiment, the information acquisition device 100 includes a posture data acquisition unit, which acquires posture data of the insole user while standing or walking. The insole selection device 300 includes a posture database, in which the posture data acquired by the posture data acquisition unit is recorded in association with an identification number. Furthermore, when selecting a combination of the base insole 10 and the reinforcing insoles 11 to 17, the insole selection unit 360 also uses the posture data recorded in the posture database, thereby taking the posture of the insole user into consideration and selecting and presenting more appropriate insoles.

[0085] (Fifth embodiment) Next, a fifth embodiment of the present invention will be described. Description of content that overlaps with the first to fourth embodiments will be omitted. In this embodiment, the insole selection device 300 includes a shoe database and a shoe selection unit, and the insole presentation device 200 includes a shoe presentation unit. The shoe database stores information about shoes associated with insoles. The shoe selection unit selects appropriate shoe information from the shoe database based on the insole information selected by the insole selection unit 360, and the shoe presentation unit presents the selected shoe information to the operator of the insole presentation device 200. The insole selection unit 360 may also reselect the shape and material of the insole based on the information about the shoe selected by the shoe selection unit (for example, the structure and material of the outsole or upper of the shoe).

[0086] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
