[0023] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, the dimensional proportions in the drawings are exaggerated for the convenience of explanation and may differ from the actual proportions.

[0024] (Overall composition) FIG. 1 is a diagram showing the overall configuration of an information processing system 1 according to this embodiment. The information processing system 1 includes an information processing device 10, which is a service management server, a terminal device 20, and a monitoring support system 30 (also simply referred to as equipment) used in each of multiple nursing care facilities 900. These devices communicate with each other via the Internet. The information processing device 10 and the terminal device 20 are managed or used by a service provider. The service provider is an operating company that provides the monitoring support service of the monitoring support system 30, which will be described later. In addition, the operating body of the nursing care facility 900 (a medical corporation or a business that provides services covered by nursing care insurance) is the user of the monitoring support service.

[0025] In the following, an example will be shown in which one monitoring support system 30 is provided in each nursing care facility 900, but this is not limiting, and one monitoring support system 30 may be provided in multiple nursing care facilities 900. For example, in cases where an operating body operates multiple geographically different nursing care facilities 900, one monitoring support system 30 controls devices in the multiple nursing care facilities 900. Furthermore, the information processing system 1 may be composed of one information processing device 10 and one monitoring support system 30, and in this case, the information processing device 10 may be configured integrally with a monitoring device 32 of the monitoring support system 30 (see FIG. 5 etc. described below).

[0026] 2 is a block diagram showing a schematic configuration of the information processing device 10. The information processing device 10 includes a control unit 110, a communication unit 120, and a storage unit .

[0027] (control unit 110) The control unit 110 includes a CPU, RAM, ROM, etc. The control unit 110 functions as an acquisition unit 111, an analysis unit 112, and an output unit 113, either alone or in cooperation with a communication unit 120.

[0028] The acquisition unit 111 acquires operation log data from the watching support system 30. The operation log data is stored in the storage unit 130. Specific examples of the operation log data will be described later.

[0029] The analysis unit 112 analyzes the operational status of the monitoring support system 30 at each nursing care facility 900 based on the operation log data stored in the storage unit 130. The analysis unit 112 also analyzes changes over time in the operational status of the monitoring support system 30 at each nursing care facility 900 based on the operation log data for a predetermined period stored in the storage unit 130. The predetermined period is a quarter, a month, or a week, and the status of the current period is compared with the status of the immediately preceding period, or the status of the current period is compared with the period at the time of introduction (start of operation). For example, if the predetermined period is one month, the average daily operational status for this month and the average daily operational status for the previous month (or for the month at the time of introduction) are calculated. Then, the rate of change (rate of increase / decrease) for the current period relative to the past period is calculated. The one month at the time of introduction is, for example, one month (weeks 2 to 6) from the first two weeks after the introduction of the monitoring service. The first two weeks are excluded because they are a period during which users learn how to use the service and have a large error.

[0030] The output unit 113 outputs the analysis result generated by the analysis unit 112. For example, it transmits it to the terminal device 20 of the service provider. By referring to the analysis result displayed on the terminal device 20, an employee 76 of the service provider determines whether the nursing care facility 900 (operating body) is utilizing the monitoring support service as intended, and considers the possibility of this operating body withdrawing from the monitoring support service.

[0031] (Communication unit 120) The communication unit 120 is an interface for transmitting and receiving data to and from each device via wired or wireless communication over the Internet.

[0032] (Storage unit 130) Various types of data, such as service-related data, are stored in the storage unit 130. The service-related data includes operation log data, operation status analysis results, service contract information, and the like.

[0033] FIG. 3 shows examples of operation log data and operation status. The details of these will be described later. The service contract information is contract information for the operating body (user) of each nursing care facility 900 regarding the services provided by the service provider. The contract information includes information on the number of devices installed in the nursing care facility 900 (the number of rooms in which the detection unit 31 described below is installed). Depending on the contract information, for example, the service provider will process monthly or yearly billing for the user and provide the corresponding nursing care monitoring support service. The operation status analysis result is the analysis result obtained by the operation status analysis process (FIG. 16) described later, and is information useful for understanding the possibility of users dropping out of the monitoring support service or for understanding dissatisfaction with the devices of the nursing care facility 900.

[0034] (Terminal device 20) 4 is a block diagram showing a schematic configuration of the terminal device 20 (which functions as a display device). The terminal device 20 is a PC (personal computer) and includes a control unit 210, a communication unit 220, a display unit 230, and an input unit 240, which are interconnected by a bus.

[0035] The control unit 210 includes a CPU, RAM, ROM, etc. The control unit 210 may also include an HDD (hard disk drive). The communication unit 220 is an interface for various local connections, such as a network interface for wired communication according to standards such as Ethernet (registered trademark), or an interface for wireless communication according to standards such as Bluetooth (registered trademark) or IEEE802.11, and communicates with devices connected via a LAN.

[0036] The display unit 230 is, for example, a liquid crystal display, and displays various information. The display unit 230 displays, for example, the analysis results provided from the output unit 113 of the information processing device 10.

[0037] The input unit 240 includes a keyboard, a numeric keypad, a mouse, etc., and is used to input various types of information.

[0038] (Monitoring Support System 30) The configuration of the watching support system 30 and the operation log data of the watching support system 30 will be described below with reference to FIGS.

[0039] 5 is a diagram showing the overall configuration of the watching support system 30. The watching support system 30 used in the nursing care facility 900 includes a detection unit 31, a terminal device 33, a staff terminal 34, and a wireless AP (access point) 35.

[0040] The detection unit 31 is placed in each room (hereinafter also referred to as living room) of the resident 70, and detects the behavior and state of the resident 70 in the room. The staff terminal 34 is a portable terminal such as a smartphone, and is used by the staff 72, such as caregivers or nurses, who provide care and nursing for the resident 70.

[0041] The terminal device 33 is a PC and is used by an administrator 74. The administrator 74 is, for example, a manager or representative of the nursing care facility 900, or a leader of the staff 72, and performs notification settings, which will be described later. Devices such as the detection unit 31, monitoring device 32, and terminal device 33 are communicatively connected to one another via a LAN. The staff terminal 34 is connected to other devices via a wireless AP 35. Furthermore, each device in the nursing care facility 900 is connected to the Internet via an RT (router).

[0042] (Detection unit 31) FIG. 6 is a diagram showing an example of a detection unit 31 installed around a bed 60 in a room of a resident 70. A detection unit 31 (also referred to as a sensor box) is placed in each room so as to monitor the room of the resident 70, which is the observation area. The detection unit 31 includes various sensors as described below, and generates sensing information from the output of the sensors. The sensing information includes not only signals from each sensor, but also, for example, a determination result of a person's movement determined by image processing from a video signal (an event as described below), and a care call signal from a care call unit 314 (described below).

[0043] Fig. 7 is a block diagram showing a schematic configuration of the detection unit 31. As shown in Fig. 7, the detection unit 31 includes a control unit 311, a communication unit 312, a camera 313, a care call unit 314, a voice input / output unit 315, and a pause switch 316, which are interconnected by a bus or short-range wireless communication.

[0044] The control unit 311 has the same configuration as the control unit 210, including a CPU, RAM, ROM, etc. The control unit 311 may also have an HDD. The control unit 311 controls each unit of the detection unit 31 and performs calculation processing according to a program. The control unit 311 functions as an event determination unit 31a.

[0045] The communication unit 312 is an interface circuit (for example, a LAN card, a wireless communication circuit, etc.) for communicating with other devices such as the monitoring device 32 via a LAN.

[0046] The camera 313 is placed, for example, on the ceiling or upper part of a wall of the room, captures an image of the bed 60 of the resident 70 directly below as an observation area, and outputs the captured image (image data). This captured image includes still images and videos. The camera 313 is a near-infrared camera, but a visible light camera may be used instead, or a combination of these may be used. The camera 313 outputs an image signal as sensing information acquired by the imaging sensor.

[0047] The care call unit 314 includes a push-button switch, and detects a care call (also called a nurse call) when the resident 70 operates this switch. Instead of a push-button switch, a care call may be detected by an audio microphone. When the switch of the care call unit 314 is pressed, that is, when a care call is detected, the control unit 311 transmits a notification that a care call has been made to the monitoring device 32, etc., via the communication unit 312 and the LAN.

[0048] The audio input / output unit 315 is, for example, a speaker and a microphone, and enables audio communication by transmitting and receiving audio signals to and from the terminal device 33 and the staff terminal 34 via the communication unit 312. The audio input / output unit 315 may be connected to the detection unit 31 via the communication unit 312 as an external device of the detection unit 31.

[0049] The pause switch 316 is placed near the entrance of the room. This pause switch 316 includes a push button switch, and when the staff member 72 or the like operates this switch when entering the room, the determination process by the event determination unit 31a of the detection unit 31, which will be described below, is temporarily stopped.

[0050] In the event determination process described below, the event determination unit 31a of the control unit 311 determines an event based on the movement of the resident 70 based on the captured image. In this case, if a third party other than the resident 70, such as a staff member 72, enters the room, the control unit 311 may not be able to distinguish between the resident 70 and the third party and may interpret the third party's actions as those of the resident 70, resulting in an unintended event determination. In other words, there is a risk of a false alarm. To prevent this, a pause switch 316 is used. Note that the pause switch 316 may be a push button type or may also be an NFC (near field communication) sensor such as FeliCa (registered trademark). For example, the pause switch is turned on / off by holding an IC card held by the staff member 72 over a reading terminal installed at the entrance / exit of the room. Operating the pause switch temporarily suspends the event determination process, but this suspension can be released by operating the pause switch again. Note that the pause switch may be automatically released after a predetermined time has elapsed, according to a setting previously made by the staff member 72 or the like.

[0051] The detection unit 31 may further include other sensors for detecting nursing care data, such as a body movement sensor, a bed sensor, a mat sensor, a thermal sensor, or an infrared sensor. This body movement sensor may be a Doppler shift sensor that transmits and receives microwaves to and from the bed 60 and detects the Doppler shift of the microwaves caused by the body movement (e.g., breathing) of the resident 70. This body movement sensor detects chest movement (up and down movement of the chest) caused by the breathing of the resident 70. If a disruption in the period of the chest body movement or an amplitude of the chest body movement below a predetermined threshold is detected, it is determined to be an abnormal micro-body movement (e.g., due to cardiac arrest). This determination of abnormal micro-body movement may be made by the detection unit 31, or may be made by the control unit 110 of the information processing device 10 by sending only a signal to the information processing device 10. This bed sensor may be any sensor that can be attached to a bed, and may, for example, detect weight and be placed on the bed 60 or on the floor at the exit of the bed 60 as the observation area, and may detect whether or not a person is standing on the sensor, or may detect the state of sleep. This infrared sensor is also called a human presence sensor, and detects whether or not a person is present in the room. For example, it may be placed throughout the room or on the bed 60 as the observation area.

[0052] (Event detection by image processing) In this embodiment, as described above, an event is a change in the state of the resident 70 detected by the detection unit 31, such as getting up, getting out of bed, falling, or abnormal slight body movement, which requires care for the resident 70 and for which an alert (notification) should be issued to the staff 72. This event also includes a care call made by the care call unit 314. The detection unit 31 transmits the determination result of the event that has occurred to the monitoring device 32.

[0053] The event determination unit 31a of the control unit 311 detects the behavior of the resident 70 from the images captured by the camera 313. The behaviors to be detected include "getting up" which is getting up from the bed 60, "getting out of bed" which is getting away from the bed 60 after getting up, "falling" which is falling off the bed 60, and "falling down" which is falling onto the floor or the like.

[0054] The event determination unit 31a detects image silhouettes (hereinafter referred to as "human silhouettes") from multiple captured images (moving images). Human silhouettes can be detected, for example, by extracting a range of pixels with relatively large differences using time subtraction, which subtracts images captured at different times. Human silhouettes may also be detected using a background subtraction method, which subtracts a background image from a captured image. When a human silhouette is detected, it is determined that a resident 70 is present in the room.

[0055] Furthermore, the area within the rectangle circumscribing the outline of the image of the resident 70 can be detected as a human rectangle circumscribing the outline of the image of the resident 70. Furthermore, together with or instead of a human silhouette obtained from the overall image of the person, a silhouette of the image of the head of the resident 70 (hereinafter referred to as a "head silhouette") may be detected. The area within the rectangle circumscribing the outline of the image of the head of the resident 70 can be detected as a head rectangle circumscribing the outline of the image of the head of the resident 70 in the captured image.

[0056] The detection of getting up, getting out of bed, falling, and tipping over is performed by detecting the posture of the resident 70 (e.g., standing, sitting, lying down, etc.) from the detected human silhouette and their relative position to objects in the room, such as the bed 60, to determine whether the event is getting up, "getting out of bed," or "falling over." For example, "getting up" can be recognized when the width of the human silhouette crossing any side of a predetermined rectangle, viewed from above, with the four corners of the bed 60 as vertices, increases to 20 cm or more. Furthermore, "getting out of bed" can be recognized when the ratio of the silhouette's area outside the rectangle to the area inside the rectangle increases to 80% or more. Furthermore, when determining the sitting position, it may also be recognized whether the sitting position is near the edge of the bed 60 (sitting on the edge of the bed 60). When the event determination unit 31a of the detection unit 31 detects any of these types of events, such as getting up, getting out of bed, or falling over, it transmits event information indicating the occurrence of the event to the monitoring device 32, etc.

[0057] Such event determination processing by the event determination unit 31a may be performed by a program processed by the CPU of the control unit 311, or by an embedded processing circuit. As another example, all or most of the detection processing may be performed on the monitoring device 32 (control unit 321) side as described above. In this case, the control unit 311 of the detection unit 31 only transmits the captured image (data related to nursing care) to the monitoring device 32, and the monitoring device 32, upon receiving this, detects an event based on the captured image.

[0058] Fig. 8 is a block diagram showing a schematic configuration of the watching device 32. The watching device 32 includes a control unit 321, a communication unit 322, and a storage unit 323. The watching device 32 is a server (edge ​​server) and provides a watching support service by working in cooperation with the information processing device 10. Note that the device configuration shown in Fig. 8 and other figures is merely an example, and some of the functions of the watching device 32 may be performed by the information processing device 10.

[0059] (Control unit 321) The control unit 321 includes a CPU, RAM, ROM, etc. The control unit 321 functions as a notification unit 32a and a notification setting unit 32b, either alone or in cooperation with the communication unit 322. When the notification unit 32a receives event information from the detection unit 31, it notifies the staff 72 in charge of caring for the resident 70 who caused the event (see step S150 in FIG. 11, which will be described later). The notification setting unit 32b sets notification ON / OFF for each room (each observation area) according to settings made by a user (e.g., an administrator 74). If notification is set to OFF, the notification unit 32a does not notify the staff 72. The notification setting procedure will be described later (see FIGS. 14 and 15, which will be described later).

[0060] The communication unit 322 is an interface circuit (for example, a LAN card, a wireless communication circuit, etc.) for communicating with other devices such as the detection unit 31 via a LAN.

[0061] (Storage unit 323) The memory unit 323 stores a resident list, a staff list, an event list, shift information, and notification settings.

[0062] The "resident list" and "staff list" include personal IDs (names and numbers), room numbers, staff names, and assigned units for residents 70 and staff 72. A unit (also called a "responsible group") is a resident unit to which multiple residents who share a common area, such as the same floor, belong, and a group to which multiple staff members who are responsible for these resident units belong. The "event list" (see Figure 12, described below) includes event information and response status. The "notification settings" are the notification ON / OFF settings for each room. The "shift information" is the working hours or working period of each staff member 72, and is recorded corresponding to the login / logoff times, as described below. Care records may also be stored. The "care records" include care record sheets, nursing record sheets (medical charts, life records), and diagnostic charts, which record the care provided to these residents 70 by staff members 72 (caregivers, nurses, etc.).

[0063] (Terminal device 33) 9 is a block diagram showing a schematic configuration of the terminal device 33. The terminal device 33 is a PC and includes a control unit 331, a communication unit 332, a display unit 333, and an input unit 334. These components are similar to those of the terminal device 20, and therefore a description thereof will be omitted. A facility manager 74 performs notification settings, which will be described later, via the terminal device 33.

[0064] (Staff terminal 34) FIG. 10 is a block diagram showing the schematic configuration of the staff terminal 34. The staff terminal 34 includes a control unit 341, a wireless communication unit 342, a display unit 343, an input unit 344, and an audio input / output unit 345, all of which are interconnected via a bus. The control unit 341 includes a CPU, RAM, ROM, and the like, similar to the control unit 311 of the detection unit 31. The wireless communication unit 342 enables wireless communication using standards such as Wi-Fi and Bluetooth (registered trademark), and wirelessly communicates with each device via the wireless AP 35 or directly. The display unit 343 and the input unit 344 are touch panels, with a touch sensor superimposed on the display surface of the display unit 343, which is composed of a liquid crystal display or the like. The display unit 343 and the input unit 344 display various operation screens (see FIG. 13, described below) that display a list of multiple events included in the event list to the staff 72, and accept various operations through these operation screens. The accepted operations are sent to the monitoring device 32 as operation information. The voice input / output unit 345 is, for example, a speaker and a microphone, and enables the staff member 72 to make voice calls to other staff terminals 34 via the wireless communication unit 342. The staff terminal 34 can be configured as, for example, a portable communication terminal device such as a tablet computer, a smartphone, or a mobile phone.

[0065] At the start and end of work, the staff member 72 performs login authentication processing and logout processing, respectively, through the staff member terminal 34 assigned to them. These periods and times are stored in the memory unit 323 as the shift information described above. The staff member 72 inputs a staff member ID and password through the touch panel (display unit 343, input unit 344) of the staff member terminal 34 and transmits them to the monitoring device 32. The monitoring device 32 compares the authentication information stored in the memory unit 323 and transmits an authentication result according to the authority of the staff member 72 to the staff member terminal 34, thereby completing the login authentication.

[0066] Each staff member 72 belongs to the unit to which they belong. For example, 24-hour care is provided to multiple residents 70 (care recipients) belonging to a resident unit in the East Wing on the second floor of a nursing facility by multiple staff members belonging to the same unit. In this case, if an event related to a resident 70 is detected in a resident unit in the East Wing on the second floor, the event information is broadcast to the staff terminals 34 of all staff members (who are logged in) belonging to the unit in charge of that resident unit, as will be described later. The resident units and the names of the members of the units to which they belong are registered in the resident list and the staff list, respectively.

[0067] (Event handling processing) FIG. 11 is a flowchart showing the process of responding to an event related to the watching support service executed by the watching support system 30.

[0068] (Step S100) Here, a login authentication process is performed. The staff member 72 inputs a staff member ID and password via the touch panel (display unit 343, input unit 344) of the staff member terminal 34 and transmits them to the watching device 32. The watching device 32 compares the authentication information stored in the memory unit 323 and transmits an authentication result according to the authority of the staff member 72 to the staff member terminal 34.

[0069] (Step S110) The detection unit 31 monitors the observation area with a camera 313 .

[0070] (Steps S120, S130) The detection unit 31 detects an event from the movement of the resident 70 in the observation area. The detection unit 31 also detects an event through the operation of the care call unit 314. Then, the communication unit 312 (acquisition unit) of the watching device 32 acquires event information of the event detected by the detection unit 31.

[0071] (Step S140) The monitoring device 32 updates the event list based on the event information acquired in step S130. FIG. 12 shows an example of the event list stored in the storage unit 323. Events included in the event list include getting up, getting out of bed, falling, tipping over, and care calls, as described above. The most recent detected event is added to the end of the event list. Each event includes "event information" and "response status" data. The event information includes an automatically assigned primary key event ID, a room number, a target person, an event type, the date and time of occurrence, and image data. The image data (photographed images i010 to i013) included in the event information is still image data captured by the detection unit 31 when the event occurred, and transmitted in step S130. The "response status" includes the status, the staff member in charge, the date and time of response, whether live images (hereinafter also referred to simply as videos) were viewed (the use of photographed images), and whether the room was visited. The staff member in charge is the staff member who took the initiative in the processing of step S180, described below, to assign themselves to the event. Here, "visiting a room" refers to the act of visiting the room of the resident 70 who caused the event to occur.

[0072] (Step S150) Here, the notification unit 32a of the monitoring device 32 notifies one or more staff members 72 of the event information newly acquired in step S120. Note that, with reference to the notification settings in the memory unit 323, if the room in which the event occurred has notifications OFF (all OFF) or if notifications for a specific event type (see FIG. 15(b) described below) are set to OFF, notification of the corresponding event is not made. If notifications are set to ON, a broadcast notification is made to simultaneously notify the staff terminals 34 of all logged-in staff members 72 belonging to the unit to which the resident 70 belongs, based on the event information. If notifications are OFF and no notification is made, the number of notifications is not counted. If notifications are ON and a notification is made, the number of notifications is counted as one. Note that FIG. 11 only shows the processing of one staff member terminal 34 used by one staff member 72 out of multiple staff members 34.

[0073] (Steps S160, S170) Each staff member 72 checks the event that has occurred through the staff terminal 34. Fig. 13 shows examples of operation screens d1 and d2 for responding to the event notification (broadcast notification) displayed on the display unit 343 of the staff terminal 34. The operation screen d1 shown in the figure is a screen that displays a list of events. The displayed events can be scrolled up and down by flicking.

[0074] Areas a10 to a12 on the operation screen d1 correspond to event IDs 010 to 013 in the event list of FIG. 12. Area a10 displays an icon indicating that event ID 010 is a care call and that the event has been addressed. Area a11 displays an icon indicating that event ID 011 is a wake-up event and that the event has been addressed. Area a12 displays icons indicating that event IDs 012 and 013 are a wake-up event and a bed-getting event and that the event has not yet been addressed. These two events are related to the same resident 70 (Mr. C), so they are displayed together in the same area. Furthermore, because the event has not yet been addressed, area a13 displays a thumbnail image (image i013) related to the most recent event (ID 013). By operating area a13, text messages can be exchanged with other staff members 72 who are logged in. By clicking area a12 on the operation screen d1, the staff member 72 transitions to operation screen d2, which is used to confirm the next event.

[0075] (Step S170) The staff member 72 checks the details of the event on the operation screen d2 displayed on the staff terminal 34. On the operation screen d2, the name of the resident (Mr. C) who caused (determined) the event and the name of the staff member (Staff Member D) using the staff terminal 34 are displayed in area a20. The time elapsed since the event occurred is displayed in area a21. The elapsed time ("1 minute elapsed") shown in area a21 is the time elapsed since the most recent event was determined (rounded down to the nearest minute). Area a21 also displays a thumbnail image (still image) of the image captured at the time of the event (leaving bed). If the thumbnail image is insufficient and the staff member 72 wants to further confirm the status of the resident 70 who caused the bed leaving or getting up event, the staff member 72 operates the "talk" or "view" buttons in areas a23 and a24 below. Operating the "talk" button allows the staff member 72 to talk to the resident 70 (Mr. C) via the audio input / output unit 315. By operating the "Watch" button, a display request is sent to the monitoring device 32, and in response, live images (real-time captured images (video)) captured by the camera 313 can be viewed by streaming playback on the operation screen d2. When the "Watch" button is operated, as shown in the video viewing column of the event list in FIG. 12, video viewing "Yes" is recorded for this event. At this time, the video viewing time and the number of calls / call time via the "Talk" button may also be recorded in association with the event.

[0076] A staff member 72 (e.g., staff member D) operates the "Respond" button (hereinafter also referred to as "request for responsibility") in area a22 to indicate that he or she wishes to take the initiative in taking charge of the displayed events (ID012, 013) for getting up and getting out of bed. If he or she does not wish to take charge, he or she can return to the previous operation screen d1 showing the event list by operating the back button (triangle icon) in the bottom column. Note that while a staff member 72 is displaying the operation screen d2 shown in FIG. 13 and checking the status of the event, the monitoring device 32 controls the prohibition process for other staff members 72. For example, even if a staff member 72 is checking the status of an event for resident 70 (Mr. C) and another staff member 72 selects the same event (ID013), the words "Checking status" are displayed on the operation screen d1 for the other staff member 72, and the "Respond" button is not displayed or cannot be selected even when the operation screen d2 is transitioned to.

[0077] (Steps S180, S190) If staff member D wishes to take the initiative and take charge of an event, he or she operates the "take charge" button (presses the take charge button). In response to staff member D, who is the terminal user, operating the "take charge" button, the staff terminal 34 sends a request to take charge of the selected event to the monitoring device 32. In response, the monitoring device 32 replies with an approval notice. Upon approval, staff member D, who sent the request, takes charge of the event, checks the status of the event via the staff terminal 34, and, if necessary, rushes to the event to take charge (visit the room), etc.

[0078] (Step S200) The monitoring device 32 updates the event list in response to the processing of step S180. Specifically, the status of the event list (IDs 012 to 013: getting out of bed, etc.) is changed to "addressed." In this embodiment, the status is changed to "addressed" in response to the staff member 72 operating the "address" button for the event selected and displayed on the operation screen d2. That is, operating the "address" button inputs a response status of "addressed," which is information indicating confirmation, and the staff member 72 who operated the button is deemed to have responded, and the response date and time are recorded. More specifically, in the event list of FIG. 12, the time when the processing of step S180 or S190 was performed is recorded in the response date and time column. In this case, the staff member 72 may end the response without rushing to the event by checking the thumbnail image on the operation screen d2 or talking to the resident 70. However, the present invention is not limited to this, and the response date and time may be recorded in the response date and time field as the time when the staff member 72 rushes to the room of the resident 70 who has experienced an event such as a fall, a tumble, or a nurse call and determines that the staff member has visited the room (step S220 described below). As another example, the response result may be entered on a separate operation screen to mark the event as completed, and the time of entry may be recorded in the response date and time field. Furthermore, when the event list is updated, the monitoring device 32 broadcasts the updated event list to all staff members who are currently logged in.

[0079] (Step S210) Here, an example will be described in which an emergency response is performed. The staff member 72 in charge of the event visits the room of the resident 70 who caused the event to respond to the emergency response.

[0080] (Step S220) When the pause switch 316 is operated, or when the room detection unit 31 (event determination unit 31a) detects a third party other than the resident 70 based on the image captured by the camera 313, i.e., when it detects the presence of multiple people, it determines that a staff member 72 has visited (entered) the room. If a visit to the room where the event occurred occurs within a predetermined time (e.g., within 10 to 15 minutes) after the event response request (S180) was made, it is deemed that the staff member 72 who made the response request (staff member D) has visited the room. When an NFC-based reading terminal placed at the entrance / exit of the room is used as the pause switch 316, the staff member 72 may hold an IC card with ID data recorded on it over the reading terminal to determine that a visit has occurred and which staff member 72 has visited the room.

[0081] (Step S230) The detection unit 31 transmits information about the staff member's visit to the monitoring device 32. The visit information includes the resident's 70 ID number.

[0082] (Step S240) The monitoring device 32 records the room visit information received in step S230 in association with the event for which the status of the resident 70 corresponding to the ID number is "completed" and which has the latest completed date and time. For example, the monitoring device 32 updates the "visited" column of the completed status of the corresponding event ID in the event list of FIG. 12 to "yes."

[0083] (Step S250) When the staff member 72 finishes working, the staff member 72 logs out by operating a "work end" button (not shown) on the staff member terminal 34. The logout time is recorded in the storage unit 323 as shift information.

[0084] (Notification settings) Next, notification settings will be described with reference to FIGS. 14 and 15. FIG. 14 shows an example of an operation screen d3 for setting notification, and FIG. 15 shows notification settings and types stored in the storage unit 323. The operation screen d3 in FIG. 14 is displayed on the display unit 333 of the terminal device 33. The administrator 74 can set notifications ON / OFF by clicking a bell icon i01 provided corresponding to each room on the operation screen d3. The notification settings are stored in the storage unit 323. In the operation screen d3 in FIG. 14, rooms 101, 104, 105, etc. are set to notification OFF and displayed as grayed out. The other rooms (rooms 102, 103, etc.) are set to notification ON. The notification settings are stored in the storage unit 323 in the format shown in FIG. 15(a). Note that the example in FIG. 14 shows an example in which two settings, ON / OFF, are performed, but multiple settings may also be performed. FIG. 15(b) shows an example in which multiple settings are performed. Notifications for each event of getting up, getting out of bed, and falling can be individually set to ON / OFF. For example, in notification setting 7, notifications for getting up and getting out of bed are OFF, and notifications for falling are ON. In this case, the responsible staff member 72 is notified of the event of falling, but notifications for other events such as getting up and getting out of bed are not sent. For example, for a resident 70 with a low level of care needs and who can walk independently and steadily, notification setting 8 (all OFF) is set; conversely, for a resident with a high level of care needs and who has difficulty walking independently, notification setting 1 (all ON) or an intermediate notification setting such as 5 (notifications for getting up OFF) is set.

[0085] Furthermore, the operation screen d3 displays the state (state, respiratory rate, heart rate) of the resident 70 obtained from the sensing information of the detection unit 31 so that the staff 72 or manager 74 can grasp the situation in each room at once. Based on the sensing information of the camera 313, it is shown that room 102 is in an awake state (wake-up event), room 202 is in a sitting state, room 301 is in an out-of-bed state (bed-out event), and room 304 is in a sleeping state. Furthermore, when the resident is asleep or awake and lying down in bed 60 (room 102, etc.), the heart rate and respiratory rate are displayed based on the sensing information of the body movement sensor.

[0086] (Operation log data and operation status) In this way, the watching device 32 acquires sensing information related to nursing care from each device in the nursing care facility 900, generates operation log data from this information, and stores it in the storage unit 323. Referring again to FIG.

[0087] (Operation log data) The operation log data is data that indicates the operation status of each device (device present in the nursing care facility 900) of the monitoring support system 30. As shown in FIG. 3(a), the operation log data includes notification settings for each room (x1), event notifications (x2), login / logout (x3), and corresponding button press information (x4).

[0088] x1: Notification setting is an ON / OFF setting of event notification for each room, set by the notification setting unit 32b as shown in FIGS.

[0089] x2: Event notification corresponds to step S130 (or step S150) in Fig. 11 described above. This is a notification to the staff terminal 34 regarding an event requiring care for the resident 70, which was detected based on sensing information from the camera 313, the event determination unit 31a, the care call unit 314, and the notification unit 32a. This notification is associated with event information (event ID, event type, date and time of occurrence, etc.) and recorded in the event list.

[0090] x3: Login / logout corresponds to steps S100 and S250 in Fig. 11 described above, and is performed by the staff terminal 34. This signal corresponds to the start and end times of work of the staff member 72 who uses this staff terminal 34, and is stored in the memory unit 323 as shift information.

[0091] x4: The response button pressing information corresponds to step S180 in Fig. 11 described above, and is performed by the staff terminal 34. The response button pressing information is a "response request" from the staff member 72, and is recorded in the event list in association with the event information.

[0092] (Operation status) The analysis unit 112 of the information processing device 10 calculates (quantifies) at least one of the operational statuses a1 to a4 shown in FIG. 3(b) based on the operation log data accumulated in the storage unit 323, and analyzes the changes.

[0093] a1 (rate of increase / decrease in the number of notifications): The analysis unit 112 calculates the rate of increase / decrease in the number of notifications using operation log data (x2: event notifications). The number of notifications is calculated by calculating the number of notifications this month (per day, per room) and the same number of notifications last month over a predetermined period (one month). Then, the ratio of the number of notifications this month to the number of notifications last month is calculated to analyze changes over time. Furthermore, if there is an increase / decrease that exceeds a certain range, for example, if the range is 50 to 200%, and it is less than 50% or more than 200%, the analysis unit 112 determines that the number is an alert (low utilization).

[0094] a2 (proportion of all notifications ON): The analysis unit 112 calculates the proportion of all notifications ON (notification ON rate) based on the operation log data (x1: notification settings) and the service contract information (number of rooms in which the detection unit 31 (sensor) is installed). Furthermore, if the recent (current) notification ON rate exceeds or is less than a certain value, the analysis unit 112 may determine that the monitoring support service is not being used appropriately and issue an alert (low utilization).

[0095] a3 (notification OFF rate): This notification OFF rate is used when notification OFF can be set in multiple stages, as in the example shown in FIG. 15(b). The analysis unit 112 calculates the ratio of the number of notification OFF settings to the setting value (number of rooms × number of notification types) obtained by multiplying the number of rooms in which the detection unit 31 is set by the number of notification OFF setting types (3). For example, in the example shown in FIG. 15(b), when notification setting 5 is set, the number of notification OFF settings in one room is one (only wake-up is OFF), when notification setting 7 is set, it is two, and when notification setting 8 is set, it is three. Similarly, when the recent (current) notification OFF rate exceeds or is below a certain value, the analysis unit 112 determines that the monitoring support service is not being used appropriately and issues an alert (low utilization).

[0096] a4 (response time increase / decrease rate): The analysis unit 112 calculates the response time using the operation log data (x2 (event notification), x4 (response button press information)). This response time corresponds to the elapsed time from step S150 (notification) to step S180 (handling request) in FIG. 11. The analysis unit 112 calculates the average response time (per notification) for this month and the average response time for the previous month for a predetermined period (one month). Then, the analysis unit 112 analyzes changes over time by calculating the ratio of this month's average response time to the previous month's average response time. If there is an increase or decrease that exceeds a certain range, for example, if the range is 50 to 200%, the analysis unit 112 determines that the increase or decrease is less than 50% or more than 200% (low utilization). For example, if the increase or decrease is extremely short, it is suspected that the response button is simply being pressed without checking the content of the event, and if the increase or decrease is extremely long, it is suspected that the response button has stopped being used.

[0097] (Analysis of operation status) Next, the processing for analyzing the operational status based on the above-mentioned operation log data will be described with reference to Fig. 16. Fig. 16 is a flowchart showing the processing for analyzing the operational status.

[0098] (Steps S310, S320) The acquisition unit 111 acquires operation log data (see FIG. 3(a)) from each of the monitoring support systems 30 of each care facility 900. The control unit 110 stores the acquired operation log data in the storage unit .

[0099] (Step S330) The control unit 110 determines whether it is time to perform an analysis. For example, it determines that an analysis should be performed every predetermined day, such as once a month, or when a request is received from the terminal device 20 (employee 76) (YES), and proceeds to step S340; otherwise (NO), it repeats the processing from step S310 onward.

[0100] (Step S340) The analysis unit 112 analyzes the operating status of one or more nursing care facilities 900 at the time of analysis. Specifically, the analysis unit 112 analyzes the current operating status (e.g., a2 and a3 in FIG. 3(b)). The analysis unit 112 also analyzes changes in the operating status over time (e.g., a1 and a4 in FIG. 3(b)).

[0101] (Step S350) The analysis unit 112 determines whether the operating status or the change in the operating status over time is outside a predetermined range. For example, if the notification ON rate (a2) exceeds a certain value, or if the ratio of the number of notifications this month (a1) to the number of notifications last month is not outside a certain range (NO), the process proceeds to step S360. On the other hand, if it is outside the predetermined range (YES), the process proceeds to step S370.

[0102] (Step S360) The output unit 113 outputs the analysis results of the operating status. For example, the output unit 113 transmits the analysis results to the terminal device 20. The employee 76 displays a plurality of pieces of operating status data for each nursing care facility 900 side by side on a dashboard displayed on the display unit 230 of the terminal device 20. For example, the service provider (employee 76, etc.) can understand the degree of utilization of the monitoring support service in a specific nursing care facility 900 by referring to the dashboard.

[0103] (Step S370) The analysis results of the operation status are output, similarly to step S360. Furthermore, the analysis unit 112 includes an alert, i.e., the analysis result indicates that the utilization of the monitoring support service of the monitoring support system 30 is low and that there is a high possibility of dropout. The output unit 113 outputs this alert together with the analysis results. For example, the alert may be output as a report together with a response method, and the relevant item (operation status item) may be highlighted with color or marking to distinguish it from other items. In this case, the analysis results of the operation status of multiple nursing care facilities 900 may be displayed as a list. The service provider can read the decline in utilization of the monitoring support system and the occurrence of some kind of trouble through the dashboard displayed on the display unit 230. The service provider can then determine the possibility of dropout from the monitoring support service of the nursing care facility 900 and take measures to prevent dropout depending on the cause.

[0104] As described above, the information processing device according to this embodiment includes an acquisition unit that acquires operation log data of the devices in the nursing care facility, an analysis unit that analyzes the operation status of the devices based on the operation log data, and an output unit that outputs the analysis results. This makes it possible to provide information that is useful for identifying in advance user dissatisfaction with the devices, i.e., information that is useful for identifying in advance signs of withdrawal due to dissatisfaction with the monitoring support service, and ultimately makes it possible to prevent withdrawal from the monitoring support service.

[0105] The configurations of the information processing device 10 and the information processing system 1 including the same described above are merely the main components used to explain the features of the above-described embodiment. However, the present invention is not limited to the above-described configurations and can be modified in various ways within the scope of the claims. For example, the information processing system 1 may be configured with the information processing device 10 and a terminal device 20 (display device) including a display unit 23. Furthermore, the processing in the information processing device 10 according to the above-described embodiment may include steps other than those shown in the flowcharts and sequence charts, or may not include some of the steps described above. Furthermore, the order of the steps is not limited to the above-described embodiment. Furthermore, each step may be combined with other steps and executed as a single step, may be included in other steps, or may be divided into multiple steps and executed.

[0106] Furthermore, the means and methods for performing various processes in the information processing device or information processing system according to the above-described embodiments can be realized by either a dedicated hardware circuit or a programmed computer. The program may be provided, for example, by a computer-readable recording medium such as a USB memory or a DVD (Digital Versatile Disc)-ROM, or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is typically transferred and stored in a storage unit such as a hard disk. The program may also be provided as standalone application software, or may be incorporated as a function into the software of a device such as a detection unit. [Explanation of symbols]
