[0024] The present invention is described below by way of the embodiments, but the present invention is not limited to the following embodiments. In addition, the structures described in the embodiments are not all necessary technical means for solving the problems. For the purpose of clear description, the following description and the accompanying drawings are appropriately omitted and simplified. In each of the accompanying drawings, the same symbols are marked for the same elements, and repeated descriptions are omitted as needed.

[0025] <Implementation method 1>

[0026] Figure 1 The block diagram shows a structural example of the motion state monitoring system 1 involved in the first embodiment. The motion state monitoring system 1 is a system for monitoring the motion state of the subject. Based on the monitoring result, a user such as a caregiver can implement support for making the motion of the subject closer to the desired motion. The following is a specific description.

[0027] like Figure 1 As shown, the action state monitoring system 1 includes an action state monitoring device 10 and a plurality of measuring instruments 20. The action state monitoring device 10 can also be referred to as an action state monitoring system as a single unit. The action state monitoring device 10 and the plurality of measuring instruments 20 are configured to be able to communicate with each other via a wired or wireless network. In addition, the action state monitoring device 10 and the plurality of measuring instruments 20 can also perform wireless communication in accordance with the Bluetooth (registered trademark) standard, short-range wireless communication in accordance with NFC (Near field communication), UWB (Ultra Wideband), WiFi (registered trademark), etc. In this embodiment, the case where 11 measuring instruments 20 are set is used as an example for explanation. In the following, the 11 measuring instruments 20 are distinguished respectively, and are also referred to as measuring instruments 20_1 to 20_11.

[0028] The measuring instruments 20_1 to 20_11 are respectively worn at the parts p_1 to p_11 of the motion detection target among various parts of the body of the subject P, and use motion sensors (hereinafter referred to as sensors) 21_1 to 21_11 composed of gyro sensors and acceleration sensors to detect the motion of the parts p_1 to p_11. In addition, the measuring instruments 20_1 to 20_11 are respectively associated with the parts p1 to p_11 by pairing processing performed between the measuring instruments 20_1 to 20_11 and the motion state monitoring device 10.

[0029] Figure 2 FIG. 2 is a diagram showing an example of the wearing target parts of the measuring instruments 20_1 to 20_11 worn on the body of the subject P. Figure 2 In the example of FIG. 1 , the wearing target parts p_1 to p_11 of the measuring instruments 20_1 to 20_11 are respectively the right upper arm, the right forearm, the head, the chest (trunk), the waist (pelvis), the left upper arm, the left forearm, the right thigh, the right calf, the left thigh, and the left calf. In addition, it is not necessary to wear all the measuring instruments 20_1 to 20_11 on the body of the subject P. Only the measuring instruments required for measuring the monitoring target action (including the movement of the part) that the user wants to monitor among the measuring instruments 20_1 to 20_11 are worn on the body of the subject P.

[0030] The monitored actions include, for example, right shoulder flexion and extension, right shoulder adduction and abduction, right shoulder internal and external rotation, right elbow flexion and extension, right forearm pronation and supination, head flexion and extension, head rotation, thoracolumbar flexion and extension, thoracolumbar rotation, thoracolumbar lateral flexion, left shoulder flexion and extension, left shoulder adduction and abduction, left shoulder internal and external rotation, left elbow flexion and extension, left forearm pronation and supination, etc. In addition, the monitored actions also include the movement of the part where the sensor is worn.

[0031] For example, the monitoring target action also includes angles of joints of the body of the subject P measured based on the detection results of multiple sensors, angles of joints in an arbitrary coordinate system measured based on the detection results of arbitrary sensors, etc. The monitoring target action can be specified by a user such as a caregiver.

[0032] Here, as an example, it is assumed that the right elbow flexion and extension movement of the subject P is monitored. The right elbow flexion and extension movement can be measured based on the detection results of the sensors worn on the right upper arm (part p1) and the right forearm (part p2). In this case, for example, two different measuring instruments are worn on the right upper arm (part p1) and the right forearm (part p2) of the subject P, respectively.

[0033] In addition, the user can also select different items of multiple monitoring target actions at the same time. For example, the user can also select "right elbow flexion and extension", "right shoulder internal and external rotation", or select "left elbow flexion and extension", "left shoulder internal and external rotation".

[0034] The right elbow flexion and extension movement can be measured based on the detection results of the sensors worn at the right upper arm (part p1) and the right forearm (part p2). Similarly, the right shoulder internal and external rotation movement can be measured based on the detection results of the sensors worn at the right upper arm (part p1) and the right forearm (part p2). In addition, the left elbow flexion and extension movement can be measured based on the detection results of the sensors worn at the left upper arm (part p6) and the left forearm (part p7). Similarly, the left shoulder internal and external rotation movement can be measured based on the detection results of the sensors worn at the left upper arm (part p6) and the left forearm (part p7).

[0035] (Configuration Example of Measuring Instruments 20_1 to 20_11)

[0036] Figure 3 20_1 is a diagram showing a configuration example of the measuring device 20_1. Since the configurations of the measuring devices 20_2 to 20_11 are the same as those of the measuring device 20_1, their description will be omitted.

[0037] like Figure 3 As shown, the measuring device 20_1 includes a sensor 21_1, a wearing pad 22_1, and a belt 23_1. The belt 23_1 is formed so as to be able to be wrapped around the motion detection target part of the subject P. The sensor 21_1 is, for example, incorporated into the wearing pad 22_1. The wearing pad 22_1 in which the sensor 21_1 is incorporated is formed on the belt 23_1 in a detachable manner.

[0038] Figure 4 FIG. 2 is a diagram showing an example of a method of wearing the measuring instrument 20_1 on the subject P. Figure 4 In the example of FIG. 1 , the belt 23_1 is wrapped around the right upper arm (part p1) of one of the motion detection target parts of the subject P. The sensor 21_1 is attached to the belt 23_1 via the wearing pad 22_1 after the correspondence establishment process and calibration are completed.

[0039] (Configuration Example of Operation Status Monitoring Device 10)

[0040] The action state monitoring device 10 is a device that outputs a calculation result representing the action state of the subject P based on the detection results (detection values) of the sensors 21_1 to 21_11. The action state monitoring device 10 may be, for example, a PC (Personal Computer), a mobile phone terminal, a smart phone, and a tablet terminal. The action state monitoring device 10 may also be configured to be able to communicate with the sensors 21_1 to 21_11 via a network not shown. The action state monitoring device 10 may also be referred to as an action state monitoring system. The action state monitoring device 10 may also include a processor and a memory storing various control programs. In this case, the action state monitoring device 10 has a function as a computer and performs processing based on various control programs, etc.

[0041] like Figure 1 As shown, the operation status monitoring device 10 includes a storage unit 11 , a display unit 12 , a designation unit 13 , a display control unit 14 , a reception unit 15 , and a processing unit 16 .

[0042] The storage unit 11 is implemented by a storage device accessible by a computer. The monitored object movement and the sensor wearing position are associated and stored in the storage unit 11. For example, the right elbow flexion and extension movement is associated with the right upper arm (part p1) and the right forearm (part p2).

[0043] The display unit 12 is, for example, a display device, and displays a plurality of sensor icons corresponding to the plurality of sensors 21_1 to 21_11, respectively. Figure 5 , an example of a display screen S displayed on the display unit 12 is shown. An area in the display screen S where sensor icons are displayed is referred to as a sensor icon display area S1. The display screen including the sensor icon display area S1 includes a human body schematic diagram S2 showing a portion of a subject where the sensor is to be worn. Figure 5 The display screen S shown is displayed when a process of establishing a one-to-one correspondence relationship between any sensor among the plurality of sensors 21 and any part of the part p of the subject P to be worn is executed.

[0044] exist Figure 5 In the illustrated example, the front side and the back side of the human body are separately displayed. Figure 2 The parts p1 to p11 of the wearing object of the subject P are respectively Figure 5The p_1 to p_11 of the human body schematic diagram S2 correspond to each other. Hereinafter, as required, the p_1 to p_11 of the human body schematic diagram S2 are referred to as the right upper arm, the right forearm, the head, the back (trunk), the waist (pelvis), the left upper arm, the left forearm, the right thigh, the right calf, the left thigh, and the left calf, respectively. In addition, the display unit 12 can display the calculation results based on the detection results of each of the more than one sensors in a graphical form, for example.

[0045] Reference Figure 1 The designation unit 13 designates the monitoring target action of the subject. The designation unit 13 may designate a plurality of monitoring target actions.

[0046] The designation unit 13 may also designate the monitored action according to the user's input operation. For example, when the display screen S includes a selection list of items of the monitored action (e.g., right shoulder flexion and extension, right shoulder adduction and abduction, etc.), the designation unit 13 may designate the monitored action selected by the user.

[0047] In addition, the designation unit 13 may also designate the monitored object action based on the input operation on the joint in the human body schematic diagram S2. Specifically, the designation unit 13 may also designate the monitored object action related to the joint tapped by the user. For example, the designation unit 13 may also designate the flexion and extension of the right elbow as the monitored object action when the user taps the right elbow of the human body schematic diagram S2. In the case where there are multiple actions related to the tapped joint, the designation unit 13 may further designate the monitored object action based on an input operation indicating the rotation direction around the joint, etc.

[0048] In addition, the designation unit 13 may determine the monitoring target action based on the history of the wearing position of the sensor. The designation unit 13 may designate the action corresponding to the last wearing position as the monitoring target action, or may designate the action corresponding to the wearing position where the sensor is worn the most times as the monitoring target action. In addition, when there are multiple actions related to the joint tapped by the user, the designation unit 13 may further designate the monitoring target action by considering the history of the wearing position of the sensor.

[0049] The designation unit 13 may also use a machine learning model to extract the features of the action from the captured image of the subject P, and designate the action corresponding to the feature as the monitoring target action. The monitoring target action can be designated by the subject P performing the same action as the monitoring target action. In addition, the designation unit 13 may also designate the monitoring target action based on information input by the user through voice or text. In this case, the designation unit 13 may also use a large-scale language model.

[0050] The display control unit 14 refers to the storage unit 11 and displays the wearing part corresponding to the specified monitoring object action on the display unit 12. For example, the display control unit 14 may set the wearing part corresponding to the monitoring object action to be displayed in a different display mode (for example, color, flashing, shadow, etc.) from other parts to emphasize the display. When multiple monitoring object actions are specified, the display control unit 14 may display the wearing part corresponding to the first monitoring object action (also called the first part) and the wearing part corresponding to the second monitoring object action (also called the second part) in different display modes (for example, flashing speed). The display control unit 14 may also make the thickness of the line surrounding the first part different from the thickness of the line surrounding the second part. In addition, the display control unit 14 may also make the size of the displayed parts different.

[0051] For example, in the case where the right elbow flexion and extension movement is specified, Figure 5 As shown, p_1 corresponding to the right upper arm (part p1) and p_2 corresponding to the right forearm (part p2) are highlighted.

[0052] The display control unit 14 may animate the human body schematic diagram S2 based on the captured image of the subject P. The user can grasp the relationship between the human body schematic diagram S2 and the body of the subject P smoothly.

[0053] In order to establish a correspondence between the sensor 21 and the part p of the wearer, the user selects the above-mentioned multiple sensor icons. The acceptance unit 15 accepts a setting action for the sensor icon displayed on the display unit 12. The setting action refers to an input action for the sensor icon for establishing a correspondence between the sensor corresponding to the sensor icon and any one of the parts p of the wearer. For example, the user moves the sensor icon i21_1 displayed on the sensor icon display area S1 to the right upper arm p_1 on the human body schematic diagram S2. Specifically, the user drags and drops the sensor icon i21_1 displayed on the sensor icon display area S1 to the right upper arm p_1 of the human body schematic diagram S2 through mouse operation or touch operation. The setting action is performed by Figure 5 The middle dotted line indicates that the user has performed a setting operation on the sensor icon. Since p_1 and p_2 are highlighted, the user can perform the setting operation smoothly.

[0054] Reference Figure 1The processing unit 16 establishes a correspondence relationship between the sensor corresponding to the sensor icon and the wearing object part of the subject P according to the set operation. The correspondence establishment process is performed in the following manner, that is, pairing is performed between the action state monitoring device 10 and the sensor 21 in advance, and the identification information of the wearing object part p and the identification information of the sensor 21 are associated with each other on the application of the action state monitoring device 10.

[0055] By displaying (for example, highlighting) the wearing part associated with the monitored target action, the action state monitoring system 1 according to the first embodiment can smoothly grasp the wearing position of the sensor and wear the sensor.

[0056] In addition, the setting action is not limited to drag and drop. The setting action can be any operation input for the displayed wearing position. The user can also click the sensor icon displayed in the sensor icon display area S1 and the wearing target part of the human body schematic diagram S2 within a predetermined time, so that the receiving unit 15 accepts the setting action.

[0057] Alternatively, the user may click on the wearable part of the human body diagram S2 to cause the accepting unit 15 to accept the setting operation. The processing unit 16 can automatically establish a correspondence between any one of the sensors corresponding to the plurality of sensor icons displayed on the display unit 12 and the wearable part p of the subject P according to the setting operation.

[0058] (Operation of the Operation Status Monitoring Device 10)

[0059] Next, use Figure 6 , the operation of the operation status monitoring device 10 is described. Figure 6 Flowchart showing the operation of the operation state monitoring device 10. Here, as described above, it is assumed that the state monitoring device 10 is used to monitor the right elbow flexion and extension of the subject P. That is, sensors are respectively worn on the right upper arm (part p1) and the right forearm (part p2) of the subject P. In addition, it is assumed that the monitored object operation and the wearing position of the sensor are associated with each other and stored in the storage unit 11.

[0060] First, the operating state monitoring device 10 causes the display unit 12 to display a plurality of sensor icons i21_1 to i21_11 corresponding to a plurality of sensors, respectively ( S11 ).

[0061] On the display unit 12, the following is displayed: Figure 5 The display screen shown includes a sensor icon display area S1 and a human body schematic diagram S2 showing the wearing object's parts.

[0062] Next, the designation unit 13 of the motion state monitoring device 10 designates the motion to be monitored (S12). For example, the designation unit 13 may designate the right elbow flexion and extension selected by the user as the motion to be monitored.

[0063] The display unit 12 displays the wear target part of the sensor for measuring the designated monitoring target action. The display unit 12 sets the right upper arm p1 and the right forearm p2 in the human body schematic diagram S2 to be displayed in a different display mode (color, flashing, shadow, etc.) than the other parts p3 to p11 and emphasizes the display. Figure 5 In the human body schematic diagram S2, the right upper arm p1 and the right forearm p2 are displayed differently from the other parts p3 to p11.

[0064] Then, in the operation state monitoring device 10, the user drags and drops one sensor icon i21_1 from the sensor icons i21_1 to i21_11 displayed in the sensor icon display area S1 to the right upper arm p_1 of the human body schematic diagram S2. As a result, the receiving unit 15 receives the setting operation (S13).

[0065] Thereafter, the action status monitoring device 10 establishes an association between the identification information of the sensor 21_1 corresponding to the sensor icon i21_1 and the identification information of the right upper arm (part p1) of the wearer of the subject P according to the set action. Thus, the correspondence establishment process (S14) between the sensor 21_1 and the right upper arm (part p1) of the subject P is implemented. In addition, for other wearer parts (right forearm (part p2)), the dragging and dropping of the sensor icon i21_2 and the correspondence establishment process between the sensor 21_2 and the right forearm (part p2) of the subject are also implemented. That is, Figure 6 S12 and S13 in the above steps can be repeatedly performed according to the number of parts of the subject where the wearing object is worn.

[0066] After establishing the correspondence between sensor 21_1 and wearing object part p1, and between sensor 21_2 and wearing object part p2, respectively, next, calibration of sensors 21_1 and 21_2 for measuring the movement of the monitoring object is performed (S15). Calibration refers to, for example, measuring the output value (error component) of the sensor used in the measurement of the movement of the monitoring object in a stationary state and subtracting the error component from the measured value. In this example, at least calibration of sensors 21_1 and 21_2 is performed. However, calibration is not limited to the case where it is performed on sensors for measuring the movement of the monitoring object, and for example, it can also be performed on all sensors 21_1 to 21_11 before the display processing of the sensor icon corresponding to the paired sensor.

[0067] After the calibration is completed, the sensors 21_1 and 21_2 are attached to the subject P ( S16 ). Thereafter, based on the detection results of the sensors 21_1 and 21_2 , the motion of the monitoring target is measured ( S17 ).

[0068] The calculation result indicating the action state of "right elbow flexion and extension" can be calculated by the difference between the detection result of the sensor 21_1 worn on the right upper arm (part p1) of the subject P and the detection result of the sensor 21_2 worn on the right forearm (part p2). The action state monitoring device 10 generates the calculation result indicating the action state of "right elbow flexion and extension" based on the detection results of the sensors 21_1 and 21_2. The display unit 12 displays the details of the measurement result (for example, a graphical measurement result, etc.).

[0069] In this way, the action state monitoring system according to the present embodiment displays the wearing part corresponding to the designated monitoring object action on the human body diagram, thereby making it possible to smoothly grasp the wearing position of the sensor and wear the sensor.

[0070] In addition, the order of processing of the operation state monitoring system 1 is not limited to Figure 6 In the order of the processes shown, for example, calibration may be performed before displaying the sensor icon corresponding to the paired sensor.

[0071] When a correspondence is established between the action of the monitored object and the wearing position of the sensor and stored in an external server, etc., the action status monitoring device 10 can also temporarily receive information from the external server, etc. and store the received information in a storage unit 11 of the action status monitoring device 10 with a temporary storage function.

[0072] The operation status monitoring device 10 may be a PC, but may also be a server which is not necessarily a personal computer.

[0073] In addition, the present disclosure can realize a part or all of the processing of the operation state monitoring system 1 by causing a CPU (Central Processing Unit) to execute a computer program.

[0074] The above-mentioned program is included in the command group (or software code) for making the computer perform one or more functions described in the embodiment when being read by the computer. The program can also be stored in a non-temporary computer-readable medium or a tangible storage medium. As a non-limiting example, the computer-readable medium or the tangible storage medium includes a random access memory (random-access memory (RAM)), a read-only memory (read-only memory (ROM)), a flash memory, a solid-state drive (solid-state drive (SSD)) or other memory technology, a read-only compact disk (CD-ROM), a digital versatile disc (digital versatile disc (DVD)), a Blu-ray (Blu-ray (registered trademark)) optical disk or other optical storage, a cassette, a magnetic tape, a magnetic disk storage or other magnetic storage device. The program can also be sent on a temporary computer-readable medium or a communication medium. As a non-limiting example, a temporary computer-readable medium or a communication medium includes an electrical, optical, acoustic or other form of transmission signal.

[0075] According to the disclosure described in this way, it is obvious that the embodiments of the present disclosure can be changed in many ways. Such changes should not be regarded as departing from the spirit and scope of the present disclosure, and, for those skilled in the art, all such modifications are obvious and are included in the scope of the technical solution.
