Mode for Carrying Out the Invention

[0016] Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. For the sake of clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same reference numerals are assigned to the same elements, and duplicate explanations are omitted as necessary.

[0017] FIG. 1 is a block diagram showing a configuration example of an operation state monitoring system 1 according to an embodiment. The operation state monitoring system 1 is a system that monitors the operation state of a subject. Based on this monitoring result, for example, a user such as a caregiver can provide support to bring the subject's movements closer to desired movements. This will be specifically described below.

[0018] As shown in FIG. 1, 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 by itself. 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 this embodiment, an example in which 11 measuring instruments 20 are provided will be described. Hereinafter, each of the 11 measuring instruments 20 will also be referred to as measuring instruments 20_1 to 20_11 for distinction.

[0019] The measuring instruments 20_1 to 20_11 are respectively attached to the parts p1 to p11 to be detected for movement among various parts of the subject P's body, and detect the movements of the parts p1 to p11 using motion sensors (hereinafter simply referred to as sensors) 21_1 to 21_11 including gyro sensors and acceleration sensors. Hereinafter, the sensors 21_1 to 21_11 will also be collectively referred to as sensor 21. The sensors 21_1 to 21_11 are respectively associated with the parts p1 to p11 by an association process performed with the operation state monitoring device 10 described below.

[0020] FIG. 2 is a diagram showing an example of the attachment target parts of the measuring instruments 20_1 to 20_11. In the example of FIG. 2, the attachment target parts p1 to p11 of the measuring instruments 20_1 to 20_11 are respectively the right upper arm, right forearm, head, back (trunk), waist (pelvis), left upper arm, left forearm, right thigh, right lower leg, left thigh, and left lower leg. In this example, the back and waist are on the back side of the subject P. It should be noted that it is not necessary to attach all of the measuring instruments 20_1 to 20_11 to the body of the subject P. Only the measuring instruments necessary for measuring the monitoring target movement (including the movement of the part) that the user wants to monitor among the measuring instruments 20_1 to 20_11 need to be attached to the body of the subject P.

[0021] (Example configuration of measuring instruments 20_1 to 20_11) Figure 3 shows an example of the configuration of measuring instrument 20_1. Note that the configurations of measuring instruments 20_2 to 20_11 are the same as those of measuring instrument 20_1, so their explanation is omitted.

[0022] As shown in Figure 3, the measuring instrument 20_1 includes a sensor 21_1, a mounting pad 22_1, and a belt 23_1. The belt 23_1 is formed to be wrapped around the area of ​​the subject P whose movement is to be detected. The sensor 21_1 is incorporated, for example, into the mounting pad 22_1. The mounting pad 22_1, into which the sensor 21_1 is incorporated, is formed to be detachably attached to the belt 23_1.

[0023] Figure 4 shows an example of how the measuring instrument 20_1 is attached to subject P. In the example in Figure 4, the belt 23_1 is wrapped around subject P's upper right arm, which is one of the body parts targeted for motion detection. The sensor 21_1 is attached to the belt 23_1 via the mounting pad 22_1 after the mapping process and calibration are completed.

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

[0025] The operating status monitoring device 10 includes a communication unit 11, an arithmetic 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 the network. The operating status monitoring device 10 can receive identification information and detection results from sensors 21_1 to 21_11 via the communication unit 11.

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

[0027] Here, the communication unit 11 performs data communication compliant with the Bluetooth® standard as short-range wireless communication. The operating status monitoring device 10 pairs with the sensor 21, which is within communication range, by exchanging identification information such as Bluetooth addresses and performing mutual authentication, and connects to the sensor 21. Once pairing is complete, the necessary information is stored on both devices, and thereafter, if the sensor 21 is within a predetermined distance from the operating status monitoring device 10, pairing is not required and a connection is established.

[0028] The arithmetic processing unit 12 performs calculations based on the detection results of each of the sensors 21_1 to 21_11 to generate calculation results that represent the operational state of the monitored movements of subject P. The monitored movements include, for example, movements such as right shoulder flexion and extension, right shoulder abduction and adduction, 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 abduction and adduction, left shoulder internal and external rotation, left elbow flexion and extension, and left forearm pronation and supination. The monitored movements also include the movement of the body parts to which the sensors are attached. For example, the monitored movements include the angles of the joints of subject P's body measured based on the detection results of multiple sensors, and the angles of the joints in an arbitrary coordinate system measured based on the detection results of any of the sensors. Hereinafter, the generation of calculation results that represent the operational state of the monitored movements will also be referred to as the measurement of the monitored movements.

[0029] For example, the arithmetic processing unit 12 performs calculations based on the detection results of sensor 21_1 attached to subject P's upper right arm (part p1) and sensor 21_2 attached to his right forearm (part p2), among the sensors 21_1 to 21_11, to generate calculation results that represent the motion state of subject P's right elbow flexion and extension movement.

[0030] Alternatively, the arithmetic processing unit 12 performs calculations based on the detection results of sensor 21_5 attached to the lower back (part p5) and sensor 21_8 attached to the right thigh (part p8) of subject P, from among sensors 21_1 to 21_11, to generate calculation results that represent the motion state of the lateral flexion movement of the right side of subject P's lower back.

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

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

[0033] The display unit 14 is a display device that displays a predetermined image on the screen. The display unit 14 displays multiple sensor icons corresponding to multiple sensors 21_1 to 21_11. Figure 5 shows an example of the display screen S displayed on the display unit 14. The area of ​​the display screen S that displays the sensor icons is called the sensor icon display area S1.

[0034] The display unit 14 can also display a diagram simulating a human body showing the mounting locations for sensors 21_1 to 21_11. Sensor icon display area S 1 The display screen includes a schematic diagram of the human body S2 showing the parts of the body to which the sensors are attached. The display screen S shown in Figure 5 is displayed, for example, when performing a process to associate one of the multiple sensors 21 with one of the parts of the subject P to which the sensors are attached.

[0035] In the example shown in Figure 5, the human body schematic diagram S2 displays the front and back sides of the human body separately. The parts p1 to p11 to which the subject P in Figure 2 is attached correspond to parts p_1 to p_11 in the human body schematic diagram S2 in Figure 5, respectively. Hereafter, parts p_1 to p_11 on the human body schematic diagram S2 will be collectively referred to as part p_. If necessary, parts p_1 to p_11 on the human body schematic diagram S2 will be referred to as the right upper arm, right forearm, head, back (trunk), waist (pelvis), left upper arm, left forearm, right thigh, right lower leg, left thigh, and 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 a graph.

[0036] Furthermore, the display unit 14, upon receiving an operation from the user, displays an input screen for information about the subject, a screen for selecting the monitoring results to be displayed on the display unit 14, and displays the monitoring results generated after monitoring the subject's operating state. In the example shown in Figure 1, the operating state monitoring device 10 includes an operation unit 13 and a 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 displays a different sensor icon for each sensor on the display unit 14 based on the identification information of the received sensors 21_1 to 21_11. That is, the display unit 14 displays a list of sensor icons corresponding to each available sensor that has not yet been associated with a mounting area. These multiple sensor icons displayed on the icon display unit S1 are selected by the user in order to associate the sensor 21 with the mounting area p of the subject.

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

[0039] This allows the user to perform a setting action on a sensor icon, and in response to the setting action, the sensor corresponding to that sensor icon is associated with the mounting location on the subject. This association process is performed by pairing the operating state monitoring device 10 and the sensor 21 in advance, and by linking the identification information of the mounting location with the identification information of the sensor 21 on the application of the operating state monitoring device 10.

[0040] When the mapping process is executed, as shown in Figure 6, the sensor icon i21_1 disappears from the icon display unit S1 and is displayed on part p_1 of the human body diagram S2. In this way, by simply moving any sensor icon to any of the parts p_1 to p_11 on the human body diagram S2, the sensor corresponding to that sensor icon can be mapped to parts p1 to p11 of subject P. Sensors 21_1 to 21_11 may be mapped to parts p1 to p11 in order. That is, sensors 21_1 to 21_11 may each be associated exclusively with parts p1 to p11.

[0041] Furthermore, multiple sensors 21 may be equipped with light-emitting units capable of changing the color of the emitted light. For example, a full-color LED can 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. By controlling the brightness of the three types of LED chips, the light-emitting unit can achieve a variety of emitted colors.

[0042] The operating status monitoring device 10 may further include a color control unit that performs a process to make the display color of multiple sensor icons the same as the emission color of the respective light-emitting parts of the multiple sensors. The user can select a sensor with the same emission color as the display color of the sensor icon, check the human body diagram S2, and actually attach it to the target part of the subject P. This makes it possible to prevent incorrect sensor installation.

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

[0044] The sensor 21 attached to subject P typically moves in three dimensions. For example, the sensor 21 is equipped with a gyroscope and can detect angular velocities around the mutually orthogonal X, Y, and Z axes. The display control unit 15 can rotate the sensor icon using, for example, the detection result from the sensor 21 for one of the X, Y, or Z axes.

[0045] The display control unit 15 can rotate the target sensor icon i21_1 around a predetermined axis in response to the rotational movement of the sensor 21_1. For example, as shown in Figure 7, the display control unit 15 can display on the display unit 14 an image of the target sensor icon i21_1 rotating around an axis passing through its center of gravity, as indicated by the dotted arrow in Figure 7.

[0046] In this way, by changing the display mode 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.

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

[0048] The process by which the display control unit 15 changes the display mode of the sensor icon in accordance with the operation of the sensor 21 may be performed before or after attaching the sensor to each part of the subject P. For example, if the sensor 21_2 is rotated before attaching it to part p2 of the subject P, the sensor icon i21_2 displayed on the icon display unit S1 may rotate, as shown in Figure 8.

[0049] When the sensor 21 is attached to subject P, it may be hidden from view if it is attached under subject P's clothing or if it is concealed by attachment components such as the mounting pad 22_1 or belt 23_1. In this case, after attaching the sensor 21 to subject P, a process is performed to change the display mode of the sensor icon according to the movement of the sensor 21, so that the sensor icon corresponding to the sensor 21 can be easily identified by simply moving the sensor 21 slightly.

[0050] Furthermore, the display control unit 15 can change the sensor icon displayed on the screen of the display unit 14 over time, not only in response to the movement of the sensor 21, but also in response to physical input to the sensor 21. For example, the sensor 21 may include an accelerometer. The display control unit 15 can change the display mode based on tap input to the sensor 21 collected by the accelerometer. For example, if a user taps the sensor 21 with a force exceeding a threshold intensity using their finger or the like, 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 state in which the switch is pressed. For example, if a user presses the switch button multiple times within a predetermined period, or presses it for a period exceeding a threshold time, the display control unit 15 can change the display mode of the corresponding sensor icon.

[0052] Furthermore, the display mode of the sensor icon may be changed based on changes 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, a user can cause changes in the atmospheric pressure or temperature around the sensor 21 by covering the sensor 21 with their hand. Also, for example, a 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 changes in atmospheric pressure, temperature, or illuminance around the sensor 21.

[0053] Furthermore, the user can generate sound near the sensor 21, for example, by snapping their fingers. The display control unit 15 can change the display mode of the corresponding sensor icon when the sensor 21 detects a sound that exceeds a threshold. Alternatively, the display mode of the sensor icon may be changed by detecting a change in radio wave intensity between the paired sensor 21 and the operating status monitoring device 10.

[0054] Furthermore, the display control unit 15 visualizes the information (calculation results) received from the calculation processing unit 12 in the form of a graph or the like, and then displays it on the display unit 14. This allows the user to know the operating status of the monitored action of subject P, which can be used, for example, to assist subject P.

[0055] (Operation of the operational status monitoring device 10) Next, the operation of the motion state monitoring device 10 will be explained using Figure 9. Figure 9 is a flowchart showing the operation of the motion state monitoring device 10. The motion state monitoring device 10 will monitor the flexion and extension of the subject P's right elbow. Specifically, sensors 21_1 and 21_2 will be associated with the subject P's upper right arm (part p1) and right forearm (part p2), respectively.

[0056] As shown in Figure 9, first the operating status monitoring device 10 displays sensor icons i21_1 to i21_11 corresponding to each of the multiple sensors located within a predetermined distance on the display unit 14 (S11). At this time, the operating status monitoring device 10 does not display multiple sensor icons for all of the sensors 21_1 to 21_11; there may be sensor icons that are not displayed depending on their distance from the operating status monitoring device 10.

[0057] Here, as an example, we assume that all sensors 21_1 to 21_11 are within a predetermined distance from the operating status monitoring device 10. Therefore, the operating status monitoring device 10 will display sensor icons i21_1 to i21_1 corresponding to all sensors 21_1 to 21_11.

[0058] The display unit 14 displays a display screen that includes a sensor icon display area S1, which displays sensor icons corresponding to sensors within a predetermined distance from the operating status monitoring device 10, as shown in Figure 5, and a schematic diagram of the human body S2, which displays the mounting target area.

[0059] Furthermore, when the user specifies the monitoring target movement of subject P, the display unit 14 may display the mounting location of the sensor used to measure the specified monitoring target movement. The display unit 14 of the motion state monitoring device 10 can highlight the upper right arm p_1 and the right forearm p2 in the human body schematic diagram S2 using a different display method (color, blinking, shading, etc.) than the other parts p3 to p11. That is, in the human body schematic diagram S2 of Figure 5, the upper right arm p_1 and the right forearm p2 may be displayed in a different manner than the other parts p3 to p11.

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

[0061] Subsequently, the operation status monitoring device 10 associates the identification information of sensor 21_1 corresponding to the sensor icon i21_1 with the identification information of the upper right arm (part p1) of subject P1, where the sensor is to be attached, according to the set operation. This completes the process of associating sensor 21_1 with subject P1's upper right arm (part p1) (S13). Similarly, for other attachment sites (right forearm (part p2)), the process of dragging and dropping sensor icon i21_2 and associating sensor 21_2 with subject P1's right forearm (part p2) is performed. In other words, steps S12 and S13 in Figure 7 can be repeated for each attachment site of subject P1.

[0062] After the correspondence between sensor 21_1 and mounting location p1, and between sensor 21_2 and mounting location p2, the sensors 21_1 and 21_2 used to measure the monitored operation are then calibrated (S14). Calibration is a process that measures the output value (error component) of the sensor used to measure the monitored operation in a stationary state, and subtracts that error component from the measured value. In this example, at least sensors 21_1 and 21_2 are calibrated. However, calibration is not limited to sensors used to measure the monitored operation; for example, it may be performed on all sensors 21_1 to 21_11 before the display process of the sensor icon corresponding to the paired sensor.

[0063] Next, sensors 21_1 and 21_2 are attached to subject P1 (S15). After that, the measuring instruments 20_1 and 20_2, each incorporating sensors 21_1 and 21_2 respectively, are attached to subject P, and then sensor 21 can be identified (S16). Sensor 21 can be identified by moving sensor 21 to change the display pattern of the sensor icon. For example, by rotating sensor 21_1, the sensor icon i21_1 rotates as shown in Figure 7. This makes it possible to identify the corresponding sensor icon displayed on the display unit 14 even when sensors 21_1 and 21_2 are not visible after attachment.

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

[0065] Thus, in the operating state monitoring system 1 according to this embodiment, by simply moving the sensor 21 slightly, 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 operating state monitoring device. As a result, the operating state monitoring system according to this embodiment can improve usability.

[0066] Furthermore, this disclosure can be implemented by having a CPU (Central Processing Unit) execute a computer program to perform some or all of the processing of the operational status monitoring system 1.

[0067] The program described above includes, when loaded into a computer, a set of instructions (or software code) for causing the computer to perform one or more of the functions described in the embodiments. The program may be stored in a non-temporary computer-readable medium or a physical storage medium. Examples, but not limited to, include RAM (Random-Access Memory), ROM (Read-Only Memory), flash memory, SSD (Solid-State Drive), or other memory technologies, CD-ROM, DVD (Digital Versatile Disc), Blu-ray® disc, or other optical disc storage, magnetic cassette, magnetic tape, magnetic disk storage, or other magnetic storage devices. The program may be transmitted over a temporary computer-readable medium or a communication medium. Examples, but not limited to, include temporary computer-readable medium or a communication medium that includes electrically, optically, acoustically, or otherwise propagating signals.
