[0003] Patent Document 1: International Publication No. 2023 / 248820 Summary of the Invention In sports and other fields, there is a desire for techniques that enable athletes to master methods of using their bodies to improve performance. For example, by having athletes master effective techniques for using muscles with significantly high strength when moving their hands or arms, performance can be improved. However, analyzing body movements sometimes requires a significant investment of time and effort, and specialized knowledge is sometimes necessary. Therefore, it is difficult for athletes to grasp their own body characteristics (e.g., areas of high muscle strength or fascial connections) through simple methods.

[0004] This invention provides a display system, display method, and program that can easily grasp body characteristics.

[0005] The display system of the present invention includes: a measuring unit that measures a first muscle force output representing the muscle force output of a specified part of the user in a first state and a second muscle force output representing the muscle force output of the specified part in a second state; a specifying unit that determines a muscle part associated with an increase in the user's muscle force output based on a comparison result of the first muscle force output and the second muscle force output; and a display control unit that displays display information including information related to the determined muscle part.

[0006] The display method of the present invention includes: a measurement step, measuring a first muscle force output representing the muscle force output of a specified part of the user in a first state and a second muscle force output representing the muscle force output of the specified part in a second state; a specific step, determining a muscle part associated with an increase in the user's muscle force output based on a comparison result of the first muscle force output and the second muscle force output; and a display control step, displaying display information containing information related to the determined muscle part.

[0007] The program involved in this invention causes a computer to perform the following steps: a measurement step, measuring a first muscle force output representing the muscle force output of a specified part of the user in a first state and a second muscle force output representing the muscle force output of the specified part in a second state; a specific step, determining the muscle part associated with the increase in the user's muscle force output based on a comparison result of the first muscle force output and the second muscle force output; and a display control step, displaying display information containing information related to the determined muscle part.

[0016] Figure 8 This is a diagram showing a cylindrical component with the same diameter at both ends. Detailed Implementation

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same or corresponding elements are labeled with the same symbols. For clarity, repeated descriptions are omitted as needed.

[0018] <Implementation Method 1> (Display System 10) refer to Figure 1 The implementation method 1 will be described below. Figure 1 This is a block diagram illustrating the configuration of the display system 10 according to the present invention. The display system 10 includes a measuring unit 1, a measuring unit 2, a display control unit 3, and a display unit 4.

[0019] Display system 10 is a system that measures a user's muscle strength output at different times at specified body parts, and determines the muscle parts associated with the increase in the user's muscle strength output based on the measurement results. Display system 10 prompts the user with information related to the determined muscle parts by displaying such information.

[0020] The following describes an example of how the display system 10 compares the magnitude of muscle force output on the medial and lateral sides of a user's upper limbs and determines the muscle sites associated with the increase in the user's muscle force output based on the comparison results. The location of the measurement object of the display system 10 is not limited to this. For example, the display system 10 can use the lower limbs, head, or torso as the measurement object.

[0021] The measuring unit 1 measures the user's muscle force output. Specifically, the measuring unit 1 measures a first muscle force output, which represents the muscle force output of a specified part of the user when it is in a first state, and a second muscle force output, which represents the muscle force output of that part when it is in a second state.

[0022] For example, the measurement unit 1 measures the muscle force output of the user's hand during palmar flexion as the first muscle force output, and measures the muscle force output of the user's hand during dorsiflexion as the second muscle force output. Palmar flexion is the action of bending the wrist towards the palm. For example, from a position where the palm is facing down and the hand is extended forward, the action of pointing the fingertips downward is equivalent to palmar flexion. Dorsiflexion is the action of bending the wrist towards the back of the hand. For example, from a position where the palm is facing down and the hand is extended forward, the action of pointing the fingertips upward is equivalent to dorsiflexion.

[0023] The measuring unit 1 can be composed of a sensor capable of measuring muscle force output. The measuring unit 1 is, for example, a load cell. A weighing sensor or a force plate can be used as the measuring unit 1. The measuring unit 1 can directly measure muscle force output by contacting the user's body parts, or indirectly by not contacting the user's body parts.

[0024] Figure 2 and Figure 3 This is a diagram illustrating a specific example of display system 10. In Figure 2 and Figure 3 In this example, the measuring unit 1 is mounted on the mounting unit 5. The mounting unit 5 can be any component installed on a wall or ceiling surface in an environment where the display system 10 is installed.

[0025] Figure 2 This illustrates an example where the measuring unit 1 is positioned above the user's hand. Figure 3 This illustrates 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 places their hand in a palmar flexion position and presses it onto the measuring unit 1. Furthermore, as shown in the lower part of each figure, the user places their hand in a dorsiflexion position and presses it onto the measuring unit 1. In each figure, hollow arrows indicate the direction of movement of the user's hand.

[0026] exist Figure 2 In the example, the user bends or dorsiflexes their hand and presses the measuring part 1 from bottom to top. Figure 3 In the example, the user presses the measuring unit 1 downwards with their palm bent or dorsiflexed. The measuring unit 1 measures the force of the user's hand pressing the measuring unit 1 in each state. The measuring unit 1 outputs the measurement result to the designated unit 2. The measuring unit 1 can send the measurement result to the designated unit 2 via a wireless or wired network (not shown).

[0027] The specific unit 2 compares the first muscle force output and the second muscle force output received from the measurement unit 1. Based on the comparison result of the first muscle force output and the second muscle force output, the specific unit 2 determines the muscle sites associated with the increase in the user's muscle force output.

[0028] A muscular region can refer to the area of ​​a muscle itself, or to the area of ​​fascia covering a muscle or organ. Below, myofascial meridians are used as examples of muscular regions. Myofascial meridians represent the network formed by the continuous connection of muscles and fascia. Examples of myofascial meridians are as follows.

[0029] Superficial Front Arm Line (SFAL) It runs along the fascia line on the front of the arm, extending from the chest to the hand. It is involved in arm flexion and internal rotation.

[0030] • Deep Front Arm Line (DFAL) It's the fascia line that runs deeper along the front of the arm. It controls the muscles of the forearm and the subtle movements of the fingers.

[0031] Superficial Back Arm Line (SBAL) It runs along the fascia line on the back of the arm, extending from the scapula to the hand. It is involved in arm extension and external rotation.

[0032] • Deep Back Arm Line (DBAL) It's the fascia line that runs deeper along the back of the arm. It helps stabilize the scapula and arm, and assists in shoulder movements.

[0033] Which hand movement, palmar flexion or dorsiflexion, increases muscle output varies from user to user. Therefore, when using the muscle output of the arm or hand, whether it is better to coordinate with the front line of the body or the rear line depends on the user. The specific unit 2 determines which movement produces greater muscle output by comparing the measurement results of the prescribed movement during palmar flexion and the prescribed movement during dorsiflexion. The prescribed movement is the movement that allows measurement of the user's muscle output when palmar flexing or dorsiflexing the hand. Here, the prescribed movement is the movement of pressing the hand onto the measuring unit 1. In addition, the specific unit 2 performs the determination separately for the left and right hands.

[0034] For example, in cases where muscle output during dorsiflexion is less than that during palmar flexion, specific section 2 determines that the muscle output of the forearm lines (SFAL, DFAL) along the myofascial meridians is high. This is because, assuming that in the palmar flexion state of the wrist, isometric contraction of the hand flexor muscles leads to facilitation of muscles along the same line on the myofascial meridians of SFAL and DFAL, thereby increasing muscle output along the myofascial meridians. In this case, muscle output within the body is increased. Furthermore, "facilitation" refers to improving the responsiveness and movement efficiency of the target myofascial meridian by applying physical stimulation, electrical stimulation, or specific movement patterns to that meridian.

[0035] Furthermore, in cases where (muscle output during dorsiflexion > muscle output during palmar flexion), specific section 2 determined that the muscle output along the posterior arm line (SBAL, DBAL) of the myofascial meridian was high. This is because, assuming that in the dorsiflexion state of the wrist, isometric contraction of the hand root extensor muscles leads to facilitation of muscles along the same line on the myofascial meridian of SBAL and DBAL, thereby increasing muscle output along the myofascial meridian. In this case, the muscle output outside the body is increased.

[0036] Return to Figure 1 The display control unit 3 displays information containing information related to the identified muscle location. The display control unit 3 can display the information on the display unit 4 or on an external device. For example, the display control unit 3 can display the information on the display unit of the user's terminal device.

[0037] The display control unit 3, for example, uses a diagram or drawing simulating the human body to display the muscle parts identified in the specific unit 2 as being associated with an increase in the user's muscle strength output. For example, the display control unit 3 can highlight the muscle parts with higher muscle strength output compared to other muscle parts.

[0038] For example, when the muscle force output during dorsiflexion is less than the muscle force output during palmar flexion, the display control unit 3 emphasizes displaying the muscle regions along the forearm line (SFAL, DFAL) (pectoralis major, latissimus dorsi, forearm flexor muscles, pectoralis minor, biceps brachii, and bulbus thumb). Furthermore, when the muscle force output during dorsiflexion is greater than the muscle force output during palmar flexion, the display control unit 3 emphasizes displaying the muscle regions along the posterior arm line (SBAL, DBAL) (trapezius, deltoid, forearm extensor muscles, rhomboids, levator scapulae, triceps brachii, and bulbus minimi).

[0039] Display unit 4 displays information under the control of display control unit 3. Display unit 4 is a display device such as a monitor. Display unit 4 is located in a position that the user can visually recognize.

[0040] Figure 4 This diagram illustrates an example of a display screen 4a displayed by display unit 4. Display screen 4a includes a human body diagram 41 simulating a human body. Furthermore, display screen 4a includes muscle regions 43, indicating muscles with high force output. Display screen 4a also includes a shadow 42 to emphasize these regions.

[0041] The configuration of the display system 10 has been described above. Furthermore, the display system 10 includes a processor, a memory, and a storage device (not shown). The storage device stores a computer program containing the processing described in this invention. The processor can read the computer program from the storage device into the memory and execute the computer program. Thus, the processor performs the functions of the specification unit 2 and the display control unit 3.

[0042] The specific unit 2 and the display control unit 3 can each be implemented by dedicated hardware. Furthermore, some or all of each component can be implemented by general-purpose or dedicated circuitry, processors, or combinations thereof. They can be composed of a single chip or multiple chips connected via a bus. Some or all of each component can be implemented by a combination of the aforementioned circuitry and a program.

[0043] For example, the specific unit 2 and the display control unit 3 can be a personal computer (PC), a smartphone, a tablet terminal, etc. Furthermore, for example, the specific unit 2, the display control unit 3, and the display unit 4 can be integrated into one unit.

[0044] (Displays the processing of system 10) refer to Figure 5 The processing performed by the display system 10 will be explained. Figure 5 This is a flowchart illustrating the processing flow performed by the display system 10.

[0045] First, the measuring unit 1 measures the first muscle force output during palmar flexion and the second muscle force output during dorsiflexion (S1). The measuring unit 1 outputs the measurement results to the identification unit 2. Next, the identification unit 2 compares the first and second muscle force outputs (S2). Then, based on the comparison results, the identification unit 2 determines the muscle location associated with the increase in the user's muscle force output (S3). The identification unit 2 generates display information containing information related to the determined muscle location (S4). The display control unit 3 displays the generated display information on the display unit 4 (S5). Thus, the display unit 4 displays as follows: Figure 4 The display shown is screen 4a.

[0046] As explained above, the display system 10 according to the present invention can prompt the user, through simple body movements, the characteristics of muscle groups that improve performance during coordinated activity (the line indicating improved performance during coordinated activity). With this configuration, the user can intuitively grasp their own body characteristics in a simple way, and thus know the desired line for conscious movement during body activity. Therefore, it is expected to improve the quality of the user's movements. Furthermore, the display system 10 does not require measuring and evaluating multiple muscle groups, thus enabling the evaluation of the user's movements in a short time with fewer measurements.

[0047] <Implementation Method 2> This embodiment is a variation of Embodiment 1. The display system 10a according to this embodiment will be described below. The basic structure of the display system 10a is as follows: Figure 1 Since they are the same, illustrations are omitted. Furthermore, the following descriptions will focus on the differences from Embodiment 1, while omitting descriptions of the similarities as appropriate.

[0048] In this embodiment, the measuring unit 1 uses cylindrical components with different diameters at both ends to measure the first and second muscle force outputs. Figure 6 and Figure 7 This is a diagram showing an example of a cylindrical component with different diameters at both ends. Figure 6 The diagram shows a cylindrical component 7A with a smaller diameter on the little finger side and a larger diameter on the thumb side. Figure 7 This is a diagram showing a cylindrical component 7B with a smaller diameter on the thumb side and a larger diameter on the little finger side. Figure 6 and Figure 7 In the upper paragraph (a), the state in which the user holds the cylindrical component 7A or 7B is shown, and in the lower paragraph (b), the overall appearance of the cylindrical component 7A or 7B is shown.

[0049] Cylindrical components 7A and 7B are generally cylindrical. The diameters of one end of cylindrical components 7A and 7B are different from the diameters of the other end. Cylindrical components 7A and 7B can be constructed from hollow or solid components. When comparing the cross-sectional areas near one end and the other end, the cross-sectional areas of cylindrical components 7A and 7B are different.

[0050] The measuring unit 1 measures the muscle force output when the user grips the cylindrical component with the smaller end placed on the little finger side as the first muscle force output, and measures the muscle force output when the user grips the cylindrical component with one end placed on the thumb side as the second muscle force output. Specifically, the measuring unit 1 measures the muscle force output when the user grips the cylindrical component 7A and performs a prescribed action as the first muscle force output, and measures the muscle force output when the user grips the cylindrical component 7B and performs a prescribed action as the second muscle force output.

[0051] The prescribed action is an action that measures the user's muscle force output when gripping the cylindrical component 7A or 7B. For example, as in Embodiment 1, the prescribed action could be the action of pressing the hand onto the measuring unit 1. Alternatively, if the cylindrical components 7A and 7B are configured to be the length of a baseball bat, the prescribed action could be an action such as hitting a ball. In this case, the measuring unit 1 could be a sensor for measuring the speed of the ball, rather than a load sensor.

[0052] The diameters of one end and the other end of the cylindrical components 7A and 7B are different, therefore the muscle force exerted when gripping them differs. For example... Figure 6 As shown, the cylindrical component 7A is configured such that the diameter is small on the little finger side and large on the thumb side. When the user grips the cylindrical component 7A, force is easily applied to the little finger side with the smaller diameter. Therefore, the user can easily exert muscle force on the little finger side within the cylindrical component 7A.

[0053] On the other hand, such as Figure 7 As shown, the cylindrical component 7B is configured such that the diameter on the thumb side is small and the diameter on the little finger side is large. When the user grips the cylindrical component 7B, force easily enters the thumb side with the smaller diameter. Therefore, in the cylindrical component 7B, the user can easily exert muscle force on the thumb side. Using this method, the specific part 2 is determined as follows.

[0054] For example, in the case where the muscle force output of tubular component 7A is greater than that of tubular component 7B, specific part 2 determines that the muscle force output of the posterior arm line (SBAL, DBAL) along the myofascial meridian is high. This is because, assuming that when gripping tubular component 7A, compared to gripping tubular component 7B, the muscle force output of the ring finger or little finger is utilized, facilitation of muscles along the same line on the myofascial meridian of SBAL and DBAL is generated, thereby increasing the muscle force output along the myofascial meridian. In this case, the muscle force output outside the body is increased.

[0055] Furthermore, in the case where the muscle force output of tubular component 7A is less than that of tubular component 7B, specific part 2 determines that the muscle force output of the forearm line (SFAL, DFAL) along the myofascial meridian is higher. This is because, assuming that when gripping tubular component 7B, compared to gripping tubular component 7A, the muscle force output exerted by the thumb or index finger leads to facilitation of muscles along the same line of the myofascial meridians of SFAL and DFAL, thereby increasing the muscle force output along the myofascial meridian. In this case, the muscle force output inside the body is increased.

[0056] Thus, the specific part 2 can determine the magnitude of muscle force output along the medial and lateral lines of the upper limb based on the measurement results obtained when the cylindrical components 7A and 7B, which have different diameters at both ends, are held respectively.

[0057] Furthermore, the above description uses examples of cylindrical components 7A and 7B with different diameters at both ends, but it is not limited to this. A cylindrical component 7C with the same diameter at both ends can also be used instead of cylindrical components 7A and 7B.

[0058] Figure 8 This diagram shows a cylindrical component 7C with the same diameter at both ends. The cylindrical component 7C is a cylindrical component with the same diameter at both ends. For example, the specific part 2 can compare the measurement results when holding the cylindrical component 7A with the measurement results when holding the cylindrical component 7C. Furthermore, the specific part 2 can compare the measurement results when holding the cylindrical component 7B with the measurement results when holding the cylindrical component 7C.

[0059] Alternatively, tubular components 7A and 7B can be omitted, and only tubular component 7C can be used. For example, by holding tubular component 7C with the little finger, ring finger, middle finger, and index finger in that order, the same phenomenon as when using tubular component 7A can be produced.

[0060] The processing performed by the display system 10a and Figure 5 The processing of the display system 10 shown is the same, so detailed description is omitted. In this embodiment, in step S1, the measuring unit 1 of the display system 10a measures the muscle force output when the user grips the cylindrical component 7A as the first muscle force output, and measures the muscle force output when the user grips the cylindrical component 7B as the second muscle force output, which is different from the processing of the display system 10.

[0061] As explained above, the display system 10a according to the present invention can achieve the same effect as embodiment 1.

[0062] Each functional component of the aforementioned display systems 10 and 10a can be implemented by hardware (e.g., hardwired electronic circuits) or by a combination of hardware and software (e.g., a combination of electronic circuits and programs that control them). For example, the present invention can also achieve arbitrary processing by having a central processing unit (CPU) execute a computer program.

[0063] When the aforementioned program is read into a computer, it includes a set of commands (or software code) for causing the computer to perform one or more functions described in the implementation. The program can be stored in various types of non-transitory computer-readable medium or tangible storage medium. As examples, but not limited to, non-transitory computer-readable medium or tangible storage medium includes random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technologies, CD-ROM, digital versatile disc (DVD), Blu-ray disc or other optical disc storage, cassette tape, magnetic tape, disk storage, or other magnetic storage devices. Furthermore, the program can also be transmitted on various types of transitory computer-readable medium or communication medium. As examples, without limitation, transitory computer-readable medium or communication medium includes electrical, optical, acoustic, or other forms of propagation signals.

[0064] The above describes the configuration and processing capabilities of display systems 10 and 10a. Furthermore, the configuration of display systems 10 and 10a described above is only one example and can be appropriately modified. For example, when some or all of the components of display systems 10 and 10a are implemented by multiple information processing devices or circuits, these devices or circuits can be centrally or distributed. For example, the information processing devices or circuits can be implemented as client-server systems, cloud computing systems, etc., connected separately via communication networks.

[0065] Furthermore, the present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the spirit of the invention. Moreover, the above-described embodiments can be implemented in any combination.
