[0002] Japanese Patent Application Laid-Open No. 2022-34449 discloses an operation state monitoring system that monitors the operation state of a subject based on detection results of a plurality of sensors respectively worn at a plurality of parts of the subject's body. Summary of the invention

[0003] In the motion monitoring system as in the related art, sometimes the wearing positions of a plurality of sensors are displayed on the display unit of the motion state monitoring device in the form of icons, etc. In this case, there is a problem that it is unclear which icon corresponds to each sensor.

[0004] The present disclosure is made in view of the above background, and its purpose is to provide an operation status monitoring system, a control method and a program product that can determine which of multiple sensors used in an operation status monitoring device corresponds to a sensor icon displayed on a display unit.

[0005] The motion status monitoring system involved in the present disclosure includes a plurality of sensors that respectively establish corresponding relationships with a plurality of parts of the body of a subject and a motion status monitoring device that monitors the motion of the subject based on the detection results from the plurality of sensors, wherein the motion status monitoring device includes: a display unit that displays a plurality of sensor icons corresponding to the plurality of sensors; and a display control unit that changes the display mode of the corresponding sensor icon based on the input from one of the plurality of sensors.

[0006] In this operation state monitoring system, the display mode of the sensor icon can be changed according to the input from the sensor. Therefore, the user can easily recognize the sensor icon corresponding to the sensor only by checking the display unit.

[0007] In addition, the motion state monitoring system can also perform calculation processing using a learned model generated by machine learning using past sensor detection results. The motion state monitoring system can more accurately calculate whether the motion state of the subject's monitored motion is good by performing calculation processing using the learned model.

[0008] Alternatively, the display control unit may change the display mode by causing the corresponding sensor icon to take an action corresponding to the action of one of the plurality of sensors. In addition, the display control unit may also rotate the corresponding sensor icon about a predetermined axis according to the rotation action of the sensor.

[0009] Alternatively, the sensor may include an acceleration sensor. Alternatively, the display control unit may change a display mode based on a tap input to the sensor collected by the acceleration sensor.

[0010] The sensor may include a switch. The display control unit may change a display mode based on a pressed state of the switch.

[0011] The display unit may display a diagram simulating a human body showing a portion where the sensor is to be worn. The sensor icon may be displayed on the portion where the sensor is to be worn.

[0012] The control method of the motion status monitoring system involved in the present disclosure is a control method of the motion status monitoring system, which includes a plurality of sensors that respectively establish corresponding relationships with a plurality of parts of the body of a subject and a motion status monitoring device that monitors the motion of the subject based on the detection results from the plurality of sensors, wherein the motion status monitoring device performs the following processing, namely: a processing of displaying a plurality of sensor icons that respectively establish corresponding relationships with the plurality of sensors; and a processing of changing the display mode of the corresponding sensor icon based on the input from one of the plurality of sensors.

[0013] In the control method of the operation state monitoring system, the display mode of the sensor icon can be changed according to the input from the sensor. Therefore, the user can easily recognize the sensor icon corresponding to the sensor only by checking the display unit.

[0014] The program product involved in the present disclosure is a program for controlling a motion state monitoring system including a plurality of sensors that respectively establish correspondences with a plurality of parts of a subject's body and a motion state monitoring device that monitors the subject's motions based on detection results from the plurality of sensors, and which enables the motion state monitoring device to perform the following processing, namely: a process of displaying a plurality of sensor icons that respectively correspond to the plurality of sensors; and a process of changing the display mode of the corresponding sensor icon based on input from one of the plurality of sensors.

[0015] In this program, the display mode of the sensor icon can be changed according to the input from the sensor. Therefore, the user can easily recognize the sensor icon corresponding to the sensor only by checking the display unit.

[0016] According to the present disclosure, it is possible to provide an operation status monitoring system, a control method, and a program capable of determining which of a plurality of sensors used in an operation status monitoring device corresponds to a sensor icon displayed on a display unit.

[0027] 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.

[0028] Figure 1 The block diagram shows a structural example of the motion state monitoring system 1 involved in the 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.

[0029] like Figure 1 As shown, the operation state monitoring system 1 includes a plurality of measuring instruments 20 and an operation state monitoring device 10. The operation state monitoring device 10 can also be referred to as an operation state monitoring system as a single unit. The operation 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, in this embodiment, an example of setting 11 measuring instruments 20 is described. Hereinafter, the 11 measuring instruments 20 are distinguished from each other and are also referred to as measuring instruments 20_1 to 20_11.

[0030] 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 the motion of the parts p_1 to p_11 is detected using motion sensors (hereinafter referred to as sensors) 21_1 to 21_11 composed of gyro sensors and acceleration sensors. Hereinafter, the sensors 21_1 to 21_11 are also collectively referred to as sensors 21. In addition, the sensors 21_1 to 21_11 establish corresponding relationships with the parts p1 to p11 respectively through the corresponding relationship establishment process performed between the sensor 21_1 to 21_11 and the motion state monitoring device 10 described below.

[0031] Figure 2 FIG. 2 is a diagram showing an example of a part where the measuring instruments 20_1 to 20_11 are worn. Figure 2In the example, the wearing 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 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. In this example, the back and the waist are the back side of the subject P. 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 20_1 to 20_11 required for measuring the monitoring object action (including the movement of the part) that the user wants to monitor are worn on the body of the subject P.

[0032] (Configuration Example of Measuring Instruments 20_1 to 20_11)

[0033] 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.

[0034] 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.

[0035] 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, which is one of the target parts for motion detection 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.

[0036] (Configuration Example of Operation Status Monitoring Device 10)

[0037] 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 (detection 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 smart phone, and a tablet terminal. The motion state monitoring device 10 is configured to be able to communicate with the sensors 21_1 to 21_11 via a network (not shown).

[0038] The operating state monitoring device 10 includes a communication unit 11, a 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 operating state monitoring device 10 can receive identification information and detection results of the sensors 21_1 to 21_11 via the communication unit 11.

[0039] In addition, the communication unit 11 may also establish a connection for short-range wireless communication and communicate. Here, the short-range wireless communication may apply various standards such as Bluetooth (registered trademark), BLE (Bluetooth Low Energy), and UWB (Ultra-Wide Band). For example, the communication unit 11 may receive respective identification information from a plurality of sensors 21_1 to 21_11 located within a predetermined distance through short-range wireless communication.

[0040] Here, it is assumed that the communication unit 11 performs data communication in accordance with the Bluetooth (registered trademark) standard as short-range wireless communication. The operation status monitoring device 10 exchanges identification information such as Bluetooth addresses with the sensor 21 present in the communication range to authenticate each other, thereby performing pairing and connecting with the sensor 21. Once pairing is completed, the required information is stored in each other's devices, and later, when the sensor 21 is within a predetermined distance from the operation status monitoring device 10, it is connected without pairing.

[0041] The calculation processing unit 12 performs calculation processing based on the detection results of each of the sensors 21_1 to 21_11, and generates a calculation result representing the action state of the monitored action of the subject P. The monitored action includes, 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, and the like. In addition, the monitored action also includes the movement of the part where the sensor is worn. For example, the monitored action also includes the angles of the joints of the body of the subject P measured based on the detection results of multiple sensors, the angles of the joints in an arbitrary coordinate system measured based on the detection results of an arbitrary sensor, and the like. Hereinafter, the generation of the calculation result representing the action state of the monitored action is also referred to as the measurement of the monitored action.

[0042] For example, the calculation processing unit 12 performs calculation processing based on the detection results of sensor 21_1 worn on the right upper arm (part p1) of the subject P and sensor 21_2 worn on the right forearm (part p2) among sensors 21_1 to 21_11, and generates a calculation result representing the action state of the right elbow flexion and extension movement of the subject P.

[0043] Alternatively, the calculation processing unit 12 performs calculation processing based on the detection results of the sensor 21_5 worn at the waist (part p5) of the subject P and the sensor 21_8 worn at the right thigh (part p8) among the sensors 21_1 to 21_11, and generates a calculation result representing the movement state of the right side lumbar lateral flexion movement of the subject P.

[0044] In addition, the calculation processing unit 12 may also perform calculation processing using a learned model generated by machine learning using past sensor detection results. The calculation processing unit 12 can perform calculation processing using the learned model to more accurately calculate whether the motion state of the monitored motion of the subject P is good. The calculation processing unit 12 sends the calculation result to the display control unit 15.

[0045] The operation unit 13 may include an input device such as a mouse and a keyboard. The operation unit 13 may also be a touch panel in which a display device and an input device are integrated. For example, the user operates the mouse or keyboard of the operation unit 13, or operates the touch panel of the operation unit 13 by touching with a touch pen or a finger, and inputs information related to the subject, monitoring results to be displayed by the display unit 14, etc.

[0046] 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. Figure 5 2 shows an example of the display screen S displayed on the display unit 14. The area in the display screen S where the sensor icons are displayed is referred to as a sensor icon display area S1.

[0047] The display unit 14 can also display a diagram simulating a human body showing the parts to be worn by the sensors 21_1 to 21_11. The display screen including the sensor icon display area S1 includes a human body schematic diagram S2 showing the parts to be worn by the sensors. Figure 5 The display screen S shown is displayed, for example, when a process of establishing a one-to-one correspondence between any sensor among the plurality of sensors 21 and any site among the sites p of the subject P to be worn is executed.

[0048] exist Figure 5In the illustrated example, the human body schematic diagram S2 separately displays the front side and the back side of the human body. Figure 2 The parts p1 to p11 of the wearing object of the subject P are respectively Figure 5 The parts p_1 to p_11 of the human body schematic diagram S2 correspond to each other. Hereinafter, the parts p_1 to p_11 on the human body schematic diagram S2 are also collectively referred to as parts p_. As needed, p_1 to p_11 of the human body schematic diagram S2 are respectively referred to as right upper arm, right forearm, head, back (torso), waist (pelvis), left upper arm, left forearm, right thigh, right calf, left thigh, and left calf. In addition, the display unit 14 can display the calculation results based on the detection results of more than one sensor, for example, in a graphical form.

[0049] In addition, the display unit 14 displays an input screen for information related to the subject, a selection screen for monitoring results to be displayed by the display unit 14, etc., or displays monitoring results generated after monitoring the motion state of the subject when accepting an operation from the user. Figure 1 In the illustrated example, the operation status 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.

[0050] The display control unit 15 displays a sensor icon different for each sensor on the display unit 14 based on the received identification information of the sensors 21_1 to 21_11. That is, a list of sensor icons corresponding to the available sensors that have not been associated with the wearable object parts is displayed on the display unit 14. In order to associate the sensor 21 with the wearable object part p of the subject, the user selects the multiple sensor icons displayed on the icon display unit S1.

[0051] For example, the user operates the operating unit 13, such as Figure 5 As shown by the dotted arrow mark, the sensor icon i21_1 displayed in the sensor icon display area S1 is moved 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 in the sensor icon display area S1 to the right upper arm p_1 of the human body schematic diagram S2 by mouse operation or touch operation.

[0052] Thus, the user's setting action for the sensor icon is accepted, and according to the setting action, a correspondence is established between the sensor corresponding to the sensor icon and the subject's wearing object part. 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 and the identification information of the sensor 21 are associated in the application of the action state monitoring device 10.

[0053] When the corresponding relationship establishment process is executed, such as Figure 6 As shown, the sensor icon i21_1 disappears from the icon display unit S1 and is displayed at the part p_1 of the human body schematic diagram S2. In this way, by a simple operation of moving any sensor icon to any part of the parts p_1 to p_11 on the human body schematic diagram S2, a corresponding relationship can be established between the sensor corresponding to the sensor icon and the parts p1 to p11 of the subject P. In addition, the sensors 21_1 to 21_11 can also be sequentially associated with the parts p1 to p11, respectively. That is, the sensors 21_1 to 21_11 are associated as being dedicated to the parts p1 to p11, respectively.

[0054] In addition, the plurality of sensors 21 may also include a light emitting unit capable of changing the color of light emitted. As the light emitting unit, for example, a full-color LED may be used. As an example, the light emitting unit may have a structure in which a red LED chip, a green LED chip, and a blue LED chip are sealed by a light-transmitting resin. The light emitting unit can realize a variety of light emission colors by controlling the brightness of the three types of LED chips.

[0055] The action state monitoring device 10 may further include a color control unit that performs processing to make the display colors of the plurality of sensor icons the same as the luminous colors of the luminous parts of the plurality of sensors. The user can select a sensor having the same luminous color as the display color of the sensor icon and confirm the human body schematic diagram S2 while actually wearing it at the part of the subject P to be worn. Thus, it is possible to prevent the sensor from being worn incorrectly.

[0056] 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 according to the input from one of the sensors 21_1 to 21_11. 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.

[0057] The sensor 21 worn on the subject P usually moves three-dimensionally. For example, the sensor 21 includes a gyro sensor and can detect angular velocities around mutually orthogonal X-axis, Y-axis, and Z-axis, respectively. The display control unit 15 can rotate the sensor icon, for example, using the detection result from the sensor 21 for any one of the X-axis, Y-axis, and Z-axis.

[0058] The display control unit 15 can rotate the sensor icon i21_1 of the object with a predetermined axis as the rotation axis according to the rotation action of the sensor 21_1. Figure 7 As shown, the display control unit 15 can make Figure 7 As indicated by the middle dotted arrow mark, an image in which the sensor icon i21_1 of the object is rotated about an axis passing through the center of gravity thereof is displayed on the display unit 14 .

[0059] In this way, by changing the display form of the sensor icon according to 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 .

[0060] 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 according to the input from the sensor. In addition, the sensor icon may also flash or vibrate.

[0061] The processing of changing the display mode of the sensor icon according to the movement of the sensor 21 by the display control unit 15 can be performed before or after the sensor is worn at each part of the subject P. For example, when the sensor 21_2 is rotated before being worn at the part p2 of the subject P, as shown in FIG. Figure 8 As shown, the sensor icon i21_2 displayed on the icon display portion S1 is rotatable.

[0062] When the sensor 21 is worn on the subject P, the sensor 21 may be worn under the clothes of the subject P, or the sensor 21 may be covered by the accessory parts such as the wearing pad 22_1 or the belt 23_1, so that it cannot be seen. In this case, after the sensor 21 is worn on the subject P, the sensor icon corresponding to the sensor 21 can be easily determined by performing a process of changing the display mode of the sensor icon according to the movement of the sensor 21 and only slightly moving the sensor 21.

[0063] In addition, the display control unit 15 is not limited to the movement of the sensor 21, and can also change the sensor icon of the object displayed on the screen of the display unit 14 over time according to the physical input to 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 the tapping 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 at an intensity exceeding a threshold intensity, the display control unit 15 can change the display mode of the corresponding sensor icon.

[0064] In addition, the sensor 21 may also 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 pressed state of the switch. For example, when the user presses the switch button multiple times within a predetermined period or presses the switch button for a time exceeding a threshold time, the display control unit 15 can change the display mode of the corresponding sensor icon.

[0065] In addition, the display mode of the sensor icon may also be changed based on changes in the surrounding environment of the sensor 21. For example, the sensor 21 may also have a detector that detects the pressure, temperature, illumination, or sound vibration of 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 hand. In addition, for example, the user can change the brightness around the sensor 21 by putting the sensor 21 into the wearing pad 22_1. The display control unit 15 can change the display mode of the corresponding sensor icon according to changes in the air pressure, temperature, or illumination around the sensor 21.

[0066] In addition, the user can generate a sound by, for example, snapping his fingers near the sensor 21. When the sensor 21 detects a sound exceeding a threshold, the display control unit 15 can change the display mode of the corresponding sensor icon. In addition, the display mode of the sensor icon can be changed by detecting a change in the radio wave strength between the paired sensor 21 and the operation status monitoring device 10.

[0067] The display control unit 15 displays the information (calculation result) received from the calculation processing unit 12 on the display unit 14 in a visualized form such as a graph. This allows the user to understand the motion state of the monitored motion of the subject P, which can help in caring for the subject P, for example.

[0068] (Operation of the Operation Status Monitoring Device 10)

[0069] Next, use Fig. 9 , the operation of the operation status monitoring device 10 is described. Fig. 9Flowchart showing the operation of the motion state monitoring device 10. Assume that the motion state monitoring device 10 monitors the right elbow flexion and extension of the subject P. That is, it is assumed that the sensors 21_1 and 21_2 correspond to the right upper arm (part p1) and the right forearm (part p2) of the subject P, respectively.

[0070] like Fig. 9 As shown, first, the operation state monitoring device 10 causes the display unit 14 to display sensor icons i21_1 to i21_11 corresponding to the plurality of sensors located within a predetermined distance (S11). At this time, the operation state monitoring device 10 does not display the plurality of sensor icons corresponding to all sensors 21_1 to 21_11, and there may be sensor icons that are not displayed depending on the distance from the operation state monitoring device 10.

[0071] Here, as an example, it is assumed that all sensors 21_1 to 21_11 are located within a predetermined distance from the operation state monitoring device 10. Therefore, it is assumed that sensor icons i21_1 to i21_1 corresponding to all sensors 21_1 to 21_11 are displayed in the operation state monitoring device 10.

[0072] On the display unit 14, the following is displayed: Figure 5 The display screen shown includes: a sensor icon display area S1 displaying sensor icons corresponding to sensors within a predetermined distance from the operation status monitoring device 10; and a human body schematic diagram S2 displaying a wearing object portion.

[0073] In addition, when the user specifies the monitoring target action of the subject P, the display unit 14 can display the wear target part of the sensor used to measure the specified monitoring target action. The display unit 14 of the motion state monitoring device 10 can set the right upper arm p_1 and the right forearm p2 to be displayed differently from the other parts p3 to p11 in the human body schematic diagram S2 and highlight them. That is, Figure 5 In the human body schematic diagram S2, the right upper arm p_1 and the right forearm p_2 can be displayed differently from the other parts p3 to p11.

[0074] Then, the user drags and drops, for example, 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. As a result, the operation state monitoring system 1 accepts the setting operation (S12).

[0075] 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 (S13) 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 P are also implemented in the same manner. That is, Fig. 9 S12 and S13 in the above steps can be repeatedly performed according to the number of parts of the subject P where the object is worn.

[0076] After establishing the correspondence between sensor 21_1 and the wearing object part p1, and between sensor 21_2 and the wearing object part p2, respectively, next, calibration of sensors 21_1 and 21_2 for measuring the movement of the monitoring object is performed (S14). 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.

[0077] Then, the sensors 21_1 and 21_2 are put on the subject P (S15). After that, after the measuring instruments 20_1 and 20_2 respectively equipped with the sensors 21_1 and 21_2 are actually put on the subject P, the sensor 21 can be determined (S16). The determination of the sensor 21 can be performed by moving the sensor 21 to change the display mode of the sensor icon. As an example, by rotating the sensor 21_1, as shown in FIG. Figure 7 As shown in FIG. 1 , the sensor icon i21_1 rotates. Thus, even when the sensors 21_1 and 21_2 are not visible after wearing, the corresponding sensor icon displayed on the display unit 14 can be identified.

[0078] Thereafter, based on the respective detection results of sensors 21_1 and 21_2, the measurement of the monitored object movement is performed (S17). The calculation result representing the movement state of "right elbow flexion and extension" can be calculated by the difference between the detection result of sensor 21_1 worn on the right upper arm (part p1) of the subject P and the detection result of sensor 21_2 worn on the right forearm (part p2). The movement state monitoring device 10 generates a calculation result representing the movement state of "right elbow flexion and extension" based on the respective detection results of sensors 21_1 and 21_2. The details of the measurement results (for example, graphical measurement results, etc.) are displayed on the display unit 14.
