DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The present invention will be described below through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. In addition, not all of the configurations described in the embodiments are necessarily essential means for solving the problems. For clarity of explanation, the following description and drawings are omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and repeated explanations are omitted as necessary.

[0017] Fig. 1 is a block diagram showing an example of the configuration of a motion state monitoring system 1 according to an embodiment. The motion state monitoring system 1 is a system that monitors the motion state of a subject. Based on the monitoring results, a user such as a caregiver can provide support to bring the motion of the subject closer to a desired motion. A specific description will be given below.

[0018] As shown in FIG. 1, the operation status monitoring system 1 includes a plurality of measuring instruments 20 and an operation status monitoring device 10. The operation status monitoring device 10 can be referred to as an operation status monitoring system by itself. The operation status 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 this embodiment, an example in which eleven measuring instruments 20 are provided will be described. Hereinafter, the eleven measuring instruments 20 will be referred to as measuring instruments 20_1 to 20_11 to distinguish them from one another.

[0019] The measuring instruments 20_1 to 20_11 are attached to the parts p1 to p11 of the body of the subject P that are to be subjected to motion detection, respectively, and detect the motion of the parts p1 to p11 using motion sensors (hereinafter simply referred to as sensors) 21_1 to 21_11 including a gyro sensor, an acceleration sensor, etc. Hereinafter, the sensors 21_1 to 21_11 are also collectively referred to as sensors 21. The sensors 21_1 to 21_11 are associated with the parts p1 to p11, respectively, by an association process performed between the sensors and the motion state monitoring device 10, which will be described below.

[0020] FIG. 2 is a diagram showing an example of target parts for attachment of the measuring devices 20_1 to 20_11. In the example of FIG. 2, target parts p1 to p11 for attachment of the measuring devices 20_1 to 20_11 are 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 lower leg, the left thigh, and the left lower leg, respectively. In this example, the back and the waist are on the rear side of the subject P. It is not necessary to attach all of the measuring devices 20_1 to 20_11 to the body of the subject P. It is sufficient that only the measuring devices necessary for measuring the monitoring target motion (including the movement of the body part) that the user wants to monitor are attached to the body of the subject P among the measuring devices 20_1 to 20_11.

[0021] (Example of configuration of measuring instruments 20_1 to 20_11) 3 is a diagram showing an example of the configuration of the measuring instrument 20_1. Note that the configurations of the measuring instruments 20_2 to 20_11 are similar to that of the measuring instrument 20_1, and therefore the description thereof will be omitted.

[0022] As shown in Fig. 3, the measuring device 20_1 has a sensor 21_1, a mounting pad 22_1, and a belt 23_1. The belt 23_1 is formed so as to be wrapped around a motion detection target part of the subject P. The sensor 21_1 is incorporated in, for example, the mounting pad 22_1. The mounting pad 22_1 in which the sensor 21_1 is incorporated is formed so as to be detachable from the belt 23_1.

[0023] Fig. 4 is a diagram showing an example of how to attach the measuring device 20_1 to the subject P. In the example of Fig. 4, the belt 23_1 is wrapped around the right upper arm, which is one of the motion detection target parts of the subject P. The sensor 21_1 is attached to the belt 23_1 via the attachment pad 22_1 after the matching process, calibration, etc. are completed.

[0024] (Example of configuration of operation status monitoring device 10) The motion state monitoring device 10 is a device that outputs a calculation result indicating the motion state of the subject P based on the detection results (sensing values) of the sensors 21_1 to 21_11. The motion state monitoring device 10 may be, for example, a PC (Personal Computer), a mobile phone terminal, a smartphone, a tablet terminal, etc. The motion state monitoring device 10 is configured to be capable of communicating with the sensors 21_1 to 21_11 via a network not shown.

[0025] The operation state monitoring device 10 includes a communication unit 11, a calculation processing unit 12, an operation unit 13, a display unit 14, and a display control unit 15. The communication unit 11 is a communication interface with a network. The operation state monitoring device 10 can receive identification information and detection results of the sensors 21_1 to 21_11 via the communication unit 11.

[0026] The communication unit 11 may establish a connection for short-distance wireless communication and perform communication. Here, various standards such as Bluetooth (registered trademark), BLE (Bluetooth Low Energy), and UWB (Ultra-Wide Band) can be applied to the short-distance wireless communication. For example, the communication unit 11 can receive identification information from each of the multiple sensors 21_1 to 21_11 located within a predetermined distance by short-distance wireless communication.

[0027] Here, the communication unit 11 performs data communication conforming to the Bluetooth (registered trademark) standard as short-distance wireless communication. The operation status monitoring device 10 is paired with the sensor 21 present within the communication range by exchanging identification information such as Bluetooth addresses and performing mutual authentication, and is then connected to the sensor 21. Once pairing is completed, necessary information is stored in each device, and thereafter, when the sensor 21 is located within a predetermined distance from the operation status monitoring device 10, connection is made without the need for pairing.

[0028] The calculation processing unit 12 performs calculation processing based on the detection results of the sensors 21_1 to 21_11, and generates a calculation result representing the motion state of the motion to be monitored of the subject P. The motion to be monitored includes, for example, right shoulder flexion and extension, right shoulder abduction and inward rotation, right shoulder internal and external rotation, right elbow flexion and extension, right forearm pronation and outward rotation, head flexion and extension, thoracic and lumbar flexion and extension, thoracic and lumbar rotation, thoracic and lumbar lateral bending, left shoulder flexion and extension, left shoulder abduction and inward rotation, left elbow flexion and extension, left forearm pronation and outward rotation, and other motions. The motion to be monitored also includes the movement of the part itself to which the sensor is attached. For example, the motion to be monitored includes the angle of the joint of the body of the subject P measured based on the detection results of multiple sensors, and the angle of the joint in an arbitrary coordinate system measured based on the detection result of any one of the sensors. Hereinafter, the generation of the calculation result representing the motion state of the motion to be monitored is also referred to as the measurement of the motion to be monitored.

[0029] For example, the calculation processing unit 12 performs calculation processing based on the detection results of each of the sensors 21_1 to 21_11, that is, the sensor 21_1 attached to the right upper arm (part p1) and the sensor 21_2 attached to the right forearm (part p2), to generate a calculation result representing the movement state of the right elbow flexion and extension movement of the subject P.

[0030] Alternatively, the calculation processing unit 12 performs calculation processing based on the detection results of each of the sensors 21_1 to 21_11, that is, the sensor 21_5 attached to the waist (area p5) of the subject P and the sensor 21_8 attached to the right thigh (area p8), to generate a calculation result representing the movement state of the right side waist lateral bending movement of the subject P.

[0031] The arithmetic processing unit 12 may perform arithmetic processing using a trained model generated by machine learning using past detection results of the sensor. By performing arithmetic processing using this trained model, the arithmetic processing unit 12 can more accurately calculate whether the motion state of the monitored motion of the subject P is good or not. The arithmetic processing unit 12 transmits the calculation result to the display control unit 15.

[0032] The operation unit 13 may include input devices such as a mouse and a keyboard. The operation unit 13 may be a touch panel in which a display device and an input device are integrated. For example, a user inputs information about the subject and monitoring results to be displayed on the display unit 14 to the display unit 14 by operating the mouse, keyboard, etc. of the operation unit 13 or by touching the touch panel of the operation unit 13 with a touch pen or a finger.

[0033] The display unit 14 is a display device that displays a predetermined image on a screen. The display unit 14 displays a plurality of sensor icons corresponding to the plurality of sensors 21_1 to 21_11, respectively. Fig. 5 shows an example of a display screen S displayed on the display unit 14. An area of ​​the display screen S that displays the sensor icons is referred to as a sensor icon display area S1.

[0034] The display unit 14 can display a diagram of a human body showing the parts to which the sensors 21_1 to 21_11 are to be attached. The display screen including the sensor icon display area S includes a human body schematic diagram S2 showing the parts to which the sensors are to be attached. The display screen S shown in Fig. 5 is displayed, for example, when performing a process of associating one of the multiple sensors 21 with one of the parts p of the subject P to which the sensors are to be attached on a one-to-one basis.

[0035] In the example shown in FIG. 5, the human body schematic diagram S2 is displayed with the front side and the back side of the human body being separated. The parts p1 to p11 of the attachment target of the subject P in FIG. 2 correspond to the parts p_1 to p_11 of the human body schematic diagram S2 in FIG. 5, respectively. Hereinafter, the parts p_1 to p_11 on the human body schematic diagram S2 are collectively referred to as parts p. If necessary, the p_1 to p_11 on 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 lower leg, the left thigh, and the left lower leg, respectively. In addition, the display unit 14 can display the calculation results based on the detection results of one or more sensors, for example, in the form of a graph.

[0036] Furthermore, when receiving an operation from a user, the display unit 14 displays an input screen for information about the subject, a selection screen for the monitoring results to be displayed on the display unit 14, and the like, and displays the monitoring results generated after monitoring the motion state of the subject. In the example shown in Fig. 1, the motion state monitoring device 10 includes the operation unit 13 and the display unit 14, but the operation unit 13 and the display unit 14 may be formed as separate operation terminals.

[0037] The display control unit 15 causes the display unit 14 to display a different sensor icon for each sensor based on the received identification information of the sensors 21_1 to 21_11. That is, a list of sensor icons corresponding to each available sensor that is not associated with an attachment target site is displayed on the display unit 14. The multiple sensor icons displayed on the icon display unit S1 are selected by the user to associate the sensor 21 with the attachment target site p of the subject.

[0038] For example, the user operates the operation unit 13 to move the sensor icon i21_1 displayed in the sensor icon display area S1 to the right upper arm p_1 on the human body schematic diagram S2, as shown by the dotted arrow in Fig. 5. Specifically, the user drags and drops the sensor icon i21_1 displayed in the sensor icon display area S1 to the right upper arm p_1 on the human body schematic diagram S2 by a mouse operation, a touch operation, or the like.

[0039] This allows the user to set the sensor icon, and the sensor corresponding to the sensor icon is associated with the subject's body part to which the sensor is to be attached in accordance with the setting operation. This association process is performed by pairing the operation status monitoring device 10 and the sensor 21 in advance, and associating the identification information of the body part to which the sensor is to be attached with the identification information of the sensor 21 on the application of the operation status monitoring device 10.

[0040] When the association process is executed, as shown in Fig. 6, the sensor icon i21_1 disappears from the icon display section S1 and is displayed on the part p_1 of the human body schematic diagram S2. In this manner, by a simple operation of moving an arbitrary sensor icon to any one of the parts p_1 to p_11 on the human body schematic diagram S2, the sensor corresponding to the sensor icon can be associated with the part p1 to p11 of the subject P. The sensors 21_1 to 21_11 may be associated with the parts p1 to p11 in order, respectively. That is, the sensors 21_1 to 21_11 may be associated exclusively with the parts p1 to p11, respectively.

[0041] The sensors 21 may each include a light-emitting unit capable of changing the color of light emitted. For example, a full-color LED may be used as the light-emitting unit. As an example, the light-emitting unit may have a configuration in which a red LED chip, a green LED chip, and a blue LED chip are sealed with a light-transmitting resin. The light-emitting unit can realize a variety of light-emitting colors by controlling the brightness of three types of LED chips.

[0042] The operating state monitoring device 10 may further include a color control unit that executes a process of making the display color of the multiple sensor icons the same as the light emission color of the light emitting units of the multiple sensors. The user can select a sensor that emits light of the same color as the display color of the sensor icon, check the human body schematic diagram S2, and actually attach the sensor to the target part of the subject P. This makes it possible to prevent the sensor from being attached incorrectly.

[0043] In response to an input from one of the sensors 21_1 to 21_11, the display control unit 15 changes the display mode of the corresponding sensor icon i21_1 to i21_11 displayed on the display unit 14. For example, the display control unit 15 can change the target sensor icon displayed on the screen of the display unit 14 over time in conjunction with the movement of the sensor 21.

[0044] The sensor 21 attached to the subject P usually moves three-dimensionally. For example, the sensor 21 includes a gyro sensor and can detect angular velocities around the mutually orthogonal X-axis, Y-axis, and Z-axis. The display control unit 15 can rotate the sensor icon using the detection result from the sensor 21 about any one of the X-axis, Y-axis, and Z-axis, for example.

[0045] The display control unit 15 can rotate the target sensor icon i21_1 around a predetermined axis as a rotation axis in response to the rotation operation of the sensor 21_1. As an example, as shown in Fig. 7, the display control unit 15 can display on the display unit 14 an image in which the target sensor icon i21_1 rotates around an axis passing through its center of gravity as a rotation axis, as shown by a dotted arrow in Fig. 7.

[0046] In this way, by changing the display mode of the sensor icon in accordance with the movement of the sensor 21, the user can easily recognize which sensor icon displayed on the display unit 14 corresponds to the sensor 21.

[0047] The change in the display mode of the sensor icon is not limited to the rotation of the sensor icon. For example, the display control unit 15 may change the color or size of the sensor icon in response to the input from the sensor. The sensor icon may also flash or vibrate.

[0048] The process of changing the display mode of the sensor icon according to the operation of the sensor 21 by the display control unit 15 may be performed before or after the sensor is attached to each part of the subject P. For example, when the sensor 21_2 is rotated before being attached to the part p2 of the subject P, the sensor icon i21_2 displayed on the icon display unit S1 may rotate as shown in FIG.

[0049] When the sensor 21 is attached to the subject P, the sensor 21 may be attached under the clothes of the subject P or may be hidden by an attachment member such as the mounting pad 22_1 or the belt 23_1, making it impossible to see. In this case, by performing a process of changing the display mode of the sensor icon according to the movement of the sensor 21 after the sensor 21 is attached to the subject P, the sensor icon corresponding to the sensor 21 can be easily identified by simply moving the sensor 21 slightly.

[0050] The display control unit 15 can also change the target sensor icon displayed on the screen of the display unit 14 over time in response to a physical input to the sensor 21, not limited to the movement of the sensor 21. For example, the sensor 21 may include an acceleration sensor. The display control unit 15 can change the display mode based on a tap input to the sensor 21 collected by the acceleration sensor. For example, when the user taps the sensor 21 with a finger or the like with a strength exceeding a threshold strength, the display control unit 15 can change the display mode of the corresponding sensor icon.

[0051] Furthermore, the sensor 21 may include a switch for changing the display mode of the sensor icon. The display control unit 15 can change the display mode based on the pressing state of the switch. For example, when the user presses the switch button multiple times within a predetermined period of time or presses it for a time exceeding a threshold time, the display control unit 15 can change the display mode of the corresponding sensor icon.

[0052] Also, the display mode of the sensor icon may be changed based on a change in the surrounding environment of the sensor 21. For example, the sensor 21 may be equipped with a detector that detects pressure, temperature, illuminance, or sound vibrations in the surrounding environment. For example, the user can change the air pressure or temperature around the sensor 21 by covering the sensor 21 with his / her hand. Also, for example, the user can change the brightness around the sensor 21 by placing the sensor 21 in the mounting pad 22_1. The display control unit 15 can change the display mode of the corresponding sensor icon in response to the change in air pressure, temperature, or illuminance around the sensor 21.

[0053] Also, the user can generate a sound, for example, by snapping his / her fingers, near the sensor 21. When the sensor 21 detects a sound whose volume exceeds a threshold, the display control unit 15 can change the display mode of the corresponding sensor icon. Also, the display control unit 15 may detect a change in radio wave intensity between the paired sensor 21 and the operation status monitoring device 10 and change the display mode of the sensor icon.

[0054] Moreover, the display control unit 15 visualizes the information (calculation results) received from the calculation processing unit 12 in a graph or the like and displays it on the display unit 14. This allows the user to know the motion state of the subject P's monitored motion, which can be useful for, for example, assisting the subject P.

[0055] (Operation of the operation status monitoring device 10) Next, the operation of the motion state monitoring device 10 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the operation of the motion state monitoring device 10. It is assumed that the motion of bending and stretching the right elbow of the subject P is monitored by the motion state monitoring device 10. That is, it is assumed that the sensors 21_1 and 21_2 are associated with the right upper arm (site p1) and the right forearm (site p2) of the subject P, respectively.

[0056] 9, the operation state monitoring device 10 first displays sensor icons i21_1 to i21_11 corresponding to each of a plurality of sensors located within a predetermined distance on the display unit 14 (S11). At this time, the operation state monitoring device 10 does not display a plurality of sensor icons corresponding to all of the sensors 21_1 to 21_11, and some sensor icons may not be displayed depending on the distance from the operation state monitoring device 10.

[0057] Here, as an example, it is assumed that all the sensors 21_1 to 21_11 are located within a predetermined distance from the operational state monitoring device 10. Therefore, it is assumed that the operational state monitoring device 10 displays sensor icons i21_1 to i21_1 corresponding to all the sensors 21_1 to 21_11, respectively.

[0058] The display unit 14 displays a display screen including a sensor icon display area S1 in which sensor icons corresponding to sensors located within a predetermined distance from the operation status monitoring device 10 are displayed, and a human body schematic diagram S2 in which the target attachment area is displayed, as shown in FIG. 5.

[0059] When the user specifies the motion of the subject P to be monitored, the display unit 14 may display the parts to which the sensor used to measure the specified motion to be monitored is attached. The display unit 14 of the motion state monitoring device 10 may highlight the right upper arm p_1 and the right forearm p2 in the human body schematic diagram S2 in a display mode (color, blinking, shading, etc.) different from the other parts p3 to p11. That is, in the human body schematic diagram S2 of FIG. 5, the right upper arm p_1 and the right forearm p2 may be displayed in a display mode different from the other parts p3 to p11.

[0060] Then, for example, 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 onto the right upper arm p_1 of the human body schematic diagram S2, whereby the motion status monitoring system 1 accepts the setting operation (S12).

[0061] Thereafter, the operating state monitoring device 10 links the identification information of the sensor 21_1 corresponding to the sensor icon i21_1 with the identification information of the right upper arm (site p1) of the subject P1 to which the sensor is to be attached, in accordance with the setting operation. As a result, a process of associating the sensor 21_1 with the right upper arm (site p1) of the subject P1 is performed (S13). Note that similarly, for another attachment target site (right forearm (site p2)), the sensor icon i21_2 is dragged and dropped, and the process of associating the sensor 21_2 with the right forearm (site p2) of the subject P1 is performed. That is, S12 and S13 in FIG. 7 can be repeated the number of times corresponding to the number of attachment target sites of the subject P1.

[0062] After the sensor 21_1 and the attachment target part p1, and the sensor 21_2 and the attachment target part p2 are associated with each other, the sensors 21_1 and 21_2 used to measure the monitored motion are calibrated (S14). The calibration is, for example, a process of measuring an output value (error component) of the sensor used to measure the monitored motion in a stationary state and subtracting the error component from an actual measurement value. In this example, calibration is performed on at least the sensors 21_1 and 21_2. However, the calibration is not limited to the case where it is performed on the sensor used to measure the monitored motion, and may be performed on all the sensors 21_1 to 21_11, for example, before a process of displaying a sensor icon corresponding to a paired sensor.

[0063] Then, the sensors 21_1 and 21_2 are attached to the subject P1 (S15). Thereafter, the measuring instruments 20_1 and 20_2 incorporating the sensors 21_1 and 21_2, respectively, are actually attached to the subject P, and then the sensor 21 can be identified (S16). The sensor 21 can be identified by moving the sensor 21 to change the display mode of the sensor icon. As an example, by rotating the sensor 21_1, the sensor icon i21_1 rotates as shown in FIG. 7. This makes it possible to identify the corresponding sensor icon displayed on the display unit 14 even if the attached sensors 21_1 and 21_2 cannot be seen.

[0064] Thereafter, the monitored motion is measured based on the detection results of the sensors 21_1 and 21_2 (S17). The calculation result showing the motion state of "right elbow flexion" can be calculated by the difference between the detection result of the sensor 21_1 attached to the right upper arm (site p1) of the subject P1 and the detection result of the sensor 21_2 attached to the right forearm (site p2). The motion state monitoring device 10 generates a calculation result showing the motion state of "right elbow flexion" based on the detection results of the sensors 21_1 and 21_2. The display unit 14 displays details of the measurement result (e.g., a graph of the measurement result).

[0065] In this way, in the operation status monitoring system 1 according to this embodiment, it is possible to identify which of the sensor icons displayed on the display unit 14 corresponds to each of the multiple sensors used in the operation status monitoring device, simply by slightly moving the sensor 21. This allows the operation status monitoring system according to this embodiment to improve usability.

[0066] Furthermore, in the present disclosure, a part or all of the processing of the operational status monitoring system 1 can be realized by causing a CPU (Central Processing Unit) to execute a computer program.
