Summary of the Invention

Problems to be Solved by the Invention

[0004] In fields such as sports, a technique for players to know how to use their bodies to improve performance is desired. For example, by knowing the muscle parts with high muscle strength and the efficient way to move the muscle parts when a player moves their hands or arms, it is possible to improve performance. However, analyzing the movement of the body may take a lot of time and effort. Also, specialized knowledge may be required in the analysis. Therefore, it is difficult for players to know the characteristics of their own bodies (for example, strong muscle parts and fascial connections) in a simple way.

[0005] This disclosure provides a display system, display method, and program that enable the easy acquisition of information about a person's physical characteristics. [Means for solving the problem]

[Effects of the Invention]

[Figure 7] Figure 7 shows a cylindrical member in which the diameter is smaller on the thumb side and larger on the little finger side. [Figure 8] Figure 8 shows a cylindrical member with the same diameter at both ends. [Modes for carrying out the invention]

[0011] Embodiments of the present disclosure will be described in detail below with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals. For clarity of explanation, redundant explanations will be omitted where necessary.

[0012] <Embodiment 1> (Display system 10) Embodiment 1 will be described with reference to Figure 1. Figure 1 is a block diagram showing the configuration of the display system 10 according to this disclosure. The display system 10 comprises a measurement unit 1, a specification unit 2, a display control unit 3, and a display unit 4.

[0013] The display system 10 is a system that measures the user's muscle output at different timings when the state of a predetermined part of the user is different, and identifies the muscle parts related to the improvement of the user's muscle output based on the measurement results. The display system 10 presents the information to the user by displaying the information related to the identified muscle parts.

[0014] Hereinafter, an example will be described in which the display system 10 compares the magnitudes of the muscle outputs of the inner and outer sides of the user's upper limb, and identifies the muscle parts related to the improvement of the user's muscle output based on the comparison results. The part to be measured by the display system 10 is not limited to this. The display system 10 may measure, for example, the lower limb, the head, or the trunk.

[0015] The measurement unit 1 measures the user's muscle output. Specifically, the measurement unit 1 measures a first muscle output indicating the muscle output when a predetermined part of the user is in the first state, and a second muscle output indicating the muscle output when the part is in the second state.

[0016] For example, the measurement unit 1 measures the muscle output when the user's hand is in palmar flexion as the first muscle output, and measures the muscle output when the user's hand is in dorsal flexion as the second muscle output. Palmar flexion is an action of bending the wrist toward the palm side. For example, the action of turning the fingertips downward from the state where the palm is facing downward and the hand is extended forward corresponds to palmar flexion. Dorsal flexion is an action of bending the wrist toward the back side. For example, the action of turning the fingertips upward from the state where the palm is facing downward and the hand is extended forward corresponds to dorsal flexion.

[0017] The measurement unit 1 may be composed of a sensor capable of measuring muscle output. The measurement unit 1 is, for example, a load sensor. As the measurement unit 1, a load cell or a force plate may be used. The measurement unit 1 may directly measure the muscle output by contacting the user's body part, or may indirectly measure the muscle output without contacting the user's body part.

[0018] Figures 2 and 3 show specific examples of the display system 10. In the examples in Figures 2 and 3, the measuring unit 1 is attached to the mounting unit 5. The mounting unit 5 may be any member provided on a wall or ceiling surface in the environment where the display system 10 is installed.

[0019] Figure 2 shows an example where the measuring unit 1 is positioned above the user's hand. Figure 3 shows an example where the measuring unit 1 is positioned below the user's hand. As shown in the upper part of each figure, the user presses their hand against the measuring unit 1 with their palm flexed. Also, as shown in the lower part of each figure, the user presses their hand against the measuring unit 1 with their hand dorsiflexed. In each figure, the direction of movement of the user's hand is indicated by a white arrow.

[0020] In the example in Figure 2, the user flexes or extends their hand and presses the measuring unit 1 from bottom to top. In the example in Figure 3, the user flexes or extends their hand and presses the measuring unit 1 from top to bottom. The measuring unit 1 measures the magnitude of the force applied by the user's hand to the measuring unit 1 in each state. The measuring unit 1 outputs the measurement result to the identification unit 2. The measuring unit 1 may also transmit the measurement result to the identification unit 2 via a wireless or wired network (not shown).

[0021] The identification unit 2 compares the first muscle output and the second muscle output received from the measurement unit 1. Based on the comparison result between the first and second muscle outputs, the identification unit 2 identifies the muscle area related to the improvement in the user's muscle output.

[0022] A muscle region can be a muscle itself, or a region of fascia covering muscles or organs. In the following, myofascial meridians are used as an example of muscle regions. Myofascial meridians represent a network formed by the continuous connection of muscles and fascia. Examples of myofascial meridians include the following:

[0023] SFAL (Superficial Front Arm Line) This is a fascial line that runs along the front of the arm, extending from the chest to the hand. It is involved in arm flexion and internal rotation. DFAL (Deep Front Arm Line) This is a fascial line that runs deeper along the front of the arm. It controls the muscles of the forearm and the fine movements of the fingers. ·SBAL (Superficial Back Arm Line) This is a fascial line that runs along the back of the arm, extending from the scapula to the hand. It is involved in arm extension and external rotation. ·DBAL (Deep Back Arm Line) This is a fascial line that runs deeper along the back of the arm. It contributes to the stability of the scapula and arm, and supports shoulder movement.

[0024] The degree to which hand movement—palmar flexion or dorsiflexion—improves muscle output varies from user to user. Therefore, when using arm and hand muscle output, it is different for users whether it is better to coordinate the front or back lines of the body. The specific unit 2 compares the measurement results of a predetermined movement in palmar flexion and a predetermined movement in dorsiflexion to determine which movement produces greater muscle output. The predetermined movement is a movement that allows measurement of the user's muscle output when the hand is in palmar flexion or dorsiflexion. In this case, the predetermined movement is the movement of pressing the hand against the measurement unit 1. The specific unit 2 performs the determination for both the left and right hands separately.

[0025] For example, if (muscle output in dorsiflexion < muscle output in palmar flexion), specific part 2 determines that the muscle output of the front arm line (SFAL, DFAL) of the myofascial meridian is high. This is because, in the palmar flexion state of the wrist, isometric contraction of the carpal flexor muscles causes facilitation of the muscles along the same line of the myofascial meridian of SFAL and DFAL, and it is assumed that the muscle output along the myofascial meridian has improved. In this case, the muscle output on the internal surface improves. Note that "facilitation" refers to the improvement in the responsiveness and operational efficiency of the target myofascial meridian by applying physical stimulation, electrical stimulation, or a specific movement pattern to that myofascial meridian.

[0026] Furthermore, if (muscle output in dorsiflexion > muscle output in palmar flexion), specific area 2 determines that the muscle output of the back arm line (SBAL, DBAL) of the myofascial meridian is high. This is because, in the dorsiflexed state of the wrist, isometric contraction of the carpal extensor muscles causes facilitation of muscles along the same line of the myofascial meridian of SBAL and DBAL, and it is assumed that the muscle output along the myofascial meridian has improved. In this case, the muscle output on the external surface of the body improves.

[0027] Returning to Figure 1, the display control unit 3 displays display information including information about the identified muscle region. The display control unit 3 may display the display information on the display unit 4, or on an external device. For example, the display control unit 3 may display the display information on the display unit of a terminal device used by the user.

[0028] The display control unit 3 displays the muscle areas identified by the identification unit 2 as being related to the improvement of the user's muscle output, for example, using a diagram or picture that mimics the human body. For example, the display control unit 3 may highlight muscle areas that have high muscle output compared to other muscle areas.

[0029] For example, if (muscle output in dorsiflexion < muscle output in palmar flexion), the display control unit 3 highlights the muscle groups of the front arm line (SFAL, DFAL) (pectoralis major, latissimus dorsi, forearm flexor muscles, pectoralis minor, biceps brachii, thenar muscles). Also, if (muscle output in dorsiflexion > muscle output in palmar flexion), the display control unit 3 highlights the muscle groups of the back arm line (SBAL, DBAL) (trapezius, deltoid, forearm extensor muscles, rhomboids, levator scapulae, triceps brachii, hypothenar muscles).

[0030] The display unit 4 displays information according to the control of the display control unit 3. The display unit 4 is a display device such as a display. The display unit 4 is installed in a position visible to the user.

[0031] Figure 4 shows an example of a display screen 4a displayed by the display unit 4. The display screen 4a includes a human body diagram 41 that mimics the human body. The display screen 4a also includes muscle area information 43 as information about muscle areas that have been determined to have high muscle output. The display screen 4a also includes shading 42 to highlight the relevant areas.

[0032] The configuration of the display system 10 has been described above. The display system 10 also includes a processor, memory, and storage device, although these are not shown in the figures. The storage device stores a computer program on which the processing described herein is implemented. The processor can load the computer program from the storage device into memory and execute the computer program. In this way, the processor realizes the functions of the specific unit 2 and the display control unit 3.

[0033] The specific unit 2 and the display control unit 3 may each be implemented with dedicated hardware. Furthermore, some or all of each component may be implemented by general-purpose or dedicated circuits, processors, etc., or combinations thereof. These may be configured by a single chip or by multiple chips connected via a bus. Some or all of each component may be implemented by a combination of the aforementioned circuits, etc., and programs.

[0034] For example, the specific unit 2 and the display control unit 3 may be a PC (Personal Computer), a smartphone, a tablet terminal, etc. Also, for example, the specific unit 2 and the display control unit 3 and the display unit 4 may be provided as an integrated unit.

[0035] (Processing by display system 10) Refer to Figure 5 to explain the processes performed by the display system 10. Figure 5 is a flowchart showing the flow of processes performed by the display system 10.

[0036] First, the measurement unit 1 measures the first muscle output when the user's hand is flexed and the second muscle output when it is flexed (S1). The measurement unit 1 outputs the measurement results to the identification unit 2. Next, the identification unit 2 compares the first muscle output and the second muscle output (S2). Subsequently, the identification unit 2 identifies the muscle area related to the improvement in the user's muscle output based on the comparison results (S3). The identification unit 2 generates display information including information about the identified muscle area (S4). The display control unit 3 displays the generated display information on the display unit 4 (S5). As a result, the display unit 4 displays a display screen 4a as shown in Figure 4.

[0037] As explained above, the display system 10 disclosed herein can present to the user the characteristics of muscle groups that improve performance when moved in coordination (lines that improve performance when moved in coordination) using simple human body movements. With this configuration, users can intuitively understand the characteristics of their own bodies in a simple way, and thus understand the lines that they should consciously move when moving their bodies. This is expected to improve the quality of the user's movements. In addition, since the display system 10 does not require the measurement and evaluation of many muscle groups, the user's body movements can be evaluated in a short time with a small number of measurements.

[0038] <Embodiment 2> This embodiment is a modification of Embodiment 1. The display system 10a according to this embodiment will be described below. The basic configuration of the display system 10a is the same as in Figure 1, so its illustration is omitted. Furthermore, the differences from Embodiment 1 will be explained below, while common points will be omitted as appropriate.

[0039] In this embodiment, the measuring unit 1 measures the first and second muscle outputs using cylindrical members with different diameters at both ends. Figures 6 and 7 show examples of cylindrical members with different diameters at both ends. Figure 6 shows a cylindrical member 7A with a smaller diameter on the little finger side and a larger diameter on the thumb side. Figure 7 shows a cylindrical member 7B with a smaller diameter on the thumb side and a larger diameter on the little finger side. In Figures 6 and 7, the upper (a) shows the user gripping the cylindrical member 7A or 7B, and the lower (b) shows the overall appearance of the cylindrical member 7A or 7B.

[0040] The cylindrical members 7A and 7B are configured to be substantially cylindrical. The cylindrical members 7A and 7B are configured such that the diameter at one end is different from the diameter at the other end. The cylindrical members 7A and 7B may be made of hollow or solid material. When comparing the cross-sections of the cylindrical members 7A and 7B near one end and near the other end, the cross-sectional areas are different.

[0041] The measuring unit 1 measures the muscle output as the first muscle output when the user grips the cylindrical member with the smaller diameter end facing the little finger, and measures the muscle output as the second muscle output when the user grips the cylindrical member with the other end facing the thumb. Specifically, the measuring unit 1 measures the muscle output as the first muscle output when the user grips the cylindrical member 7A and performs a predetermined movement, and measures the muscle output as the second muscle output when the user grips the cylindrical member 7B and performs a predetermined movement.

[0042] The predetermined action is an action that can measure the user's muscle output when gripping the cylindrical member 7A or 7B. The predetermined action may be, for example, an action such as pressing the hand against the measuring unit 1, as in Embodiment 1. Alternatively, if the cylindrical members 7A and 7B are configured to be the length of a baseball bat, the predetermined action may be an action such as hitting a ball. In this case, the measuring unit 1 may be a sensor that measures the speed of the ball, rather than a load sensor.

[0043] Since the cylindrical members 7A and 7B have different diameters at one end and the other, the muscles exerted when gripped differ. As shown in Figure 6, the cylindrical member 7A has a smaller diameter on the little finger side and a larger diameter on the thumb side. When a user grips the cylindrical member 7A, it is easier to apply force to the little finger side, which has a smaller diameter. Therefore, with the cylindrical member 7A, the user can easily exert muscle strength on the little finger side.

[0044] On the other hand, as shown in Figure 7, the cylindrical member 7B has a smaller diameter on the thumb side and a larger diameter on the little finger side. When a user grips the cylindrical member 7B, it is easier to apply force to the thumb side, which has a smaller diameter. Therefore, with the cylindrical member 7B, the user can easily exert muscle strength on the thumb side. Using this, the specific unit 2 makes the following determination.

[0045] For example, if (muscle output in cylindrical member 7A > muscle output in cylindrical member 7B), the specific unit 2 determines that the muscle output of the back arm line (SBAL, DBAL) of the myofascial meridian is high. This is because when gripping cylindrical member 7A, the muscle output of the ring finger and little finger is exerted more than when gripping cylindrical member 7B, and it is assumed that muscle facilitation occurs in the same line of the myofascial meridian of SBAL and DBAL, resulting in an improvement in muscle output along the myofascial meridian. In this case, the muscle output on the external surface of the body improves.

[0046] Furthermore, if (muscle output in cylindrical member 7A < muscle output in cylindrical member 7B), the specific unit 2 determines that the muscle output of the front arm line (SFAL, DFAL) of the myofascial meridian is high. This is because, when gripping cylindrical member 7B, the muscle output of the thumb and index finger is exerted more than when gripping cylindrical member 7A, and it is assumed that facilitation of muscles along the same line occurs in the myofascial meridians of SFAL and DFAL, resulting in improved muscle output along the myofascial meridian. In this case, the muscle output on the internal surface improves.

[0047] In this way, the specific unit 2 can determine the relative magnitudes of muscle output along the medial and lateral lines of the upper limb based on the measurement results when gripping each of the cylindrical members 7A and 7B, which have ends with different diameters.

[0048] In the above explanation, examples of cylindrical members 7A and 7B with different diameters at both ends were used, but the explanation is not limited to these. A cylindrical member 7C with the same diameter at both ends may be used instead of cylindrical members 7A and 7B.

[0049] Figure 8 shows a cylindrical member 7C with the same diameter at both ends. The cylindrical member 7C is a cylindrical member with the same diameter at both ends. For example, the specific unit 2 may compare the measurement result when gripping cylindrical member 7A with the measurement result when gripping cylindrical member 7C. Alternatively, the specific unit 2 may compare the measurement result when gripping cylindrical member 7B with the measurement result when gripping cylindrical member 7C.

[0050] Alternatively, only the cylindrical member 7C may be used without using the cylindrical members 7A and 7B. For example, the same phenomenon as when using the cylindrical member 7A can be produced by the user gripping the cylindrical member 7C in the order of little finger, ring finger, middle finger, and index finger.

[0051] The processing performed by the display system 10a is equivalent to that of the display system 10 shown in Figure 5, so a detailed explanation will be omitted. In this embodiment, in step S1, the measurement unit 1 of the display system 10a differs from the display system 10 in that it measures the muscle output when the user grips the cylindrical member 7A as the first muscle output, and measures the muscle output when the user grips the cylindrical member 7B as the second muscle output.

[0052] As described above, the display system 10a according to this disclosure can achieve the same effects as in Embodiment 1.

[0053] Each functional component of the display systems 10 and 10a described above may be implemented by hardware (e.g., hardwired electronic circuits) or by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls it). For example, the present disclosure can also be implemented by having a CPU (Central Processing Unit) execute a computer program.

[0054] The program, when loaded into a computer, includes a set of instructions (or software code) for causing the computer to perform one or more of the functions described in the embodiments. The program may be stored in various types of non-transitory computer-readable medium or tangible storage medium. Examples, but not limited to, include RAM (Random-Access Memory), ROM (Read-Only Memory), flash memory, SSD (Solid-State Drive), or other memory technologies, CD-ROM, DVD (Digital Versatile Disc), Blu-ray® disc, or other optical disc storage, magnetic cassette, magnetic tape, magnetic disk storage, or other magnetic storage devices. The program may also be transmitted over various types of transient computer-readable medium or communication medium. Examples, but not limited to, include transient computer-readable medium or communication medium, including electrically, optically, acoustically, or otherwise propagating signals.

[0055] The configuration and processing of the display systems 10 and 10a have been described above. Note that the configurations of the display systems 10 and 10a described above are merely examples and can be modified as appropriate. For example, if some or all of the components of the display systems 10 and 10a are implemented by multiple information processing devices or circuits, these devices may be centrally located or distributed. For example, the information processing devices or circuits may be implemented in a form where each is connected via a communication network, such as a client-server system or a cloud computing system.

[0056] This disclosure is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. Furthermore, the embodiments described above can be combined in any way. [Explanation of Symbols]
