The staff terminal 34 connects with other devices via the wireless AP 35 . Further, each device in the nursing care facility 900 is connected to the Internet via an RT (router).

(Detector 31)
FIG. 6 is a diagram showing an example of the detector 31 installed around the bed 60 in the room of the resident 70. As shown in FIG. The detection unit 31 is also called a sensor box or a monitoring support sensor, and is arranged in each room so as to monitor the room of the resident 70, which is an observation area. The detection unit 31 includes various sensors as described later, and generates sensing information from outputs of the sensors. Sensing information includes not only the signal of each sensor but also, for example, the determination result of a person's movement determined by image processing from a video signal (event described later) and a care call signal from the care call unit 314 (described later).

FIG. 7 is a block diagram showing a schematic configuration of the detector 31. As shown in FIG. 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, an audio input/output unit 315, and a pause switch 316, which are connected by bus or short-range wireless communication. , are interconnected.

The control unit 311 has a configuration similar to that of the control unit 210, such as a CPU, a RAM, and a ROM. Also, the control unit 311 may include an HDD. The control unit 311 controls each unit of the detection unit 31 and performs arithmetic processing according to a program. The control unit 311 functions as an event determination unit 31a.

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 watching device 32 via a LAN.

The camera 313 is arranged, for example, on the ceiling or the upper part of the wall of the living room, photographs the bed 60 of the resident 70 directly below as an observation area, and outputs a photographed image (image data). The captured images include still images and moving images. The camera 313 is a near-infrared camera, but a visible light camera may be used instead, or both of them may be used. The camera 313 outputs an image signal as sensing information acquired by the imaging sensor.

The care call unit 314 includes a push-button switch, which is operated by the resident 70 to detect a care call (also referred to as a nurse call). A voice microphone may be used to detect a care call instead of the push-button switch. When the switch of care call unit 314 is pressed, that is, when a care call is detected, control unit 311 transmits a notification that there is a care call to watching device 32 or the like via communication unit 312 and LAN.

The voice input/output unit 315 is, for example, a speaker and a microphone, and enables voice communication by transmitting and receiving voice signals to and from the terminal device 33 and the staff terminal 34 via the communication unit 312 . Note that the voice 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 .

A pause switch 316 is arranged near the doorway of the living room. The temporary stop switch 316 includes a push button type switch, and a temporary stop signal is sent to the control unit 311 by operating this switch when the staff member 72 or the like enters the living room. In response to this temporary stop signal, the determination processing by the event determination section 31a of the detection section 31, which will be described below, is temporarily stopped.

In event determination processing, which will be described later, 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, when a third party such as a staff member 72 other than the resident 70 enters the living room, the control unit 311 side cannot distinguish between the resident 70 and the third party, and the action of the third party is detected. There is a possibility that the behavior of the resident 70 may be regarded as an unintended event determination. That is, there is a risk of false alarms occurring. To prevent this, a pause switch 316 is utilized. It should be noted that the temporary stop switch 316 may be replaced with a push button type, or may be combined with an NFC (near field communication) type sensor such as FeliCa (registered trademark). For example, the temporary stop switch is turned ON/OFF by holding an IC card possessed by the staff member 72 over a reading terminal arranged at the doorway of the living room. By operating the temporary stop switch, the event determination process is temporarily stopped, but this cancellation is performed by operating the temporary stop switch again. It should be noted that it may be automatically canceled after the elapse of a predetermined time according to a preset setting by the staff member 72 or the like.

The detection unit 31 may further include a body motion sensor, a bed sensor, a mat sensor, a thermal sensor, or an infrared sensor as other sensors for detecting nursing care data. This body motion sensor may be a Doppler shift type sensor that transmits and receives microwaves to and from the bed 60 and detects the Doppler shift of the microwaves caused by body motion (for example, respiratory motion) of the resident 70 . This body motion sensor detects the body motion of the chest (up and down motion of the chest) associated with the breathing motion of the resident 70 . When the disturbance of the cycle of the chest body movement or the amplitude of the chest body movement that is equal to or less than a preset threshold value is detected, it is determined that there is an abnormal micromotion (for example, due to cardiac arrest). The determination of the abnormality in microbody motion may be performed by the detection unit 31 side, or may be performed 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 a sensor that is attached to the bed. may be detected, or a sleeping state may be detected. This infrared sensor is also called a human sensor and detects whether or not there is a person in the living room. For example, the entire living room or the top of the bed 60 is arranged as the observation area.

(Event judgment by image processing)
In the present embodiment, as described above, the change in the state detected by the detection unit 31 regarding the resident 70 requires care for the resident 70, such as getting up, getting out of bed, falling, abnormal micromovement, etc. An event that should be notified to the staff member 72 is called an event. This event also includes a care call by the care call unit 314 . The detection unit 31 transmits the determination result of the occurred event to the watching device 32 .

The event determination unit 31 a of the control unit 311 detects the behavior of the resident 70 from the captured image captured by the camera 313 . The behaviors to be detected include "getting up" from the bed 60, "getting out of bed" from the bed 60 after getting up, "falling" from the bed 60, and "falling" to the floor or the like.

The event determination unit 31a detects image silhouettes (hereinafter referred to as “human silhouettes”) from a plurality of captured images (moving images). A human silhouette can be detected, for example, by extracting a range of pixels having a relatively large difference based on a time difference obtained by subtracting images captured at different times. A person silhouette may be detected by a background subtraction method in which a background image is subtracted from a captured image. It is assumed that the resident 70 is in the room by detecting a person silhouette.

Also, the area within the rectangle circumscribed by the contour of the image of the resident 70 can be detected as the human rectangle circumscribed by the contour of the image of the resident 70 . In addition to or instead of the person silhouette obtained from the full image of the person, the silhouette of the head image of the resident 70 (hereinafter referred to as "head silhouette") may be detected. A region within the rectangle circumscribing the contour of the head image of the resident 70 can be detected as the head rectangle circumscribing the contour of the head image of the resident 70 in the captured image.

The detection of getting up, leaving the bed, falling, and falling is performed based on the posture of the resident 70 (for example, standing, sitting, lying down, etc.) from the detected human silhouette, and from the position relative to the installation in the living room such as the bed 60. , "getting out of bed" and "falling" are detected. For example, "getting up" can be recognized by the fact that the width of a person's silhouette crossing any side of a preset quadrangle with the four corners of the bed 60 as vertices has increased to 20 cm or more. Also, for example, "getting out of bed" can be recognized when the ratio of the outside area of the person silhouette to the inside of the rectangle increases to 80% or more. Further, when determining the sitting position, it may be recognized whether the sitting position is a sitting position near the side of the bed 60 (at the time of sitting on the edge). When the event determination unit 31a of the detection unit 31 detects any type of event such as getting up, getting out of bed, or falling, the event determination unit 31a transmits event information indicating that the event has occurred to the watching device 32 or the like.

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 may be performed by a built-in processing circuit. As another example, as described above, the monitoring device 32 (control unit 321) may perform all or most of these detection processes. In this case, the control unit 311 of the detection unit 31 only transmits the photographed image (data related to nursing care) to the monitoring device 32, and the monitoring device 32 that receives this detects the event based on the photographed image. .

FIG. 8 is a block diagram showing a schematic configuration of the watching device 32. As shown in FIG. The watching device 32 includes a control section 321 , a communication section 322 and a storage section 323 . The watching device 32 is a server (edge server), and cooperates with the information processing device 10 to provide a watching support service. Note that the device configuration shown in FIG. 8 and the like is merely an example, and a part of the functions of the watching device 32 may be performed on the information processing device 10 side.

(control unit 321)
The control unit 321 includes a CPU, RAM, ROM, and the like. The control unit 321 functions independently or in cooperation with the communication unit 322 as the notification unit 32a. When the notification unit 32a receives event information from the detection unit 31, the notification unit 32a notifies the staff member 72 who takes care of the resident 70 who caused the event (see step S150 in FIG. 11 described later).

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.

(storage unit 323)

Then, the communication unit 312 (acquisition unit) of the watching device 32 acquires the event information of the event detected by the detection unit 31 .

(Step S140)
The watching device 32 updates the event list with the event information acquired in step S130. FIG. 12 is an example of an event list stored in the storage unit 323. As shown in FIG. Events included in the event list include getting up, getting out of bed, falling, falling, and care call (also referred to as care call event) as described above. The latest 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, room number, target person, event type, date and time of occurrence (time), and image data information. The image data (photographed images i010 to i013) included in the event information is data of still images obtained by photographing by the detection unit 31 when the event occurs, which is transmitted in step S130. The "response status" includes status, response staff, response date (time), live image (hereinafter simply referred to as moving image) viewing or not (use of captured image), and room visit or not. The corresponding staff is a staff member who has taken the initiative in the process of step S180, which will be described later. Here, "visiting the room" means an act of visiting the living room of the resident 70 who caused the event.

(Step S150)
Here, the notification unit 32a of the watching device 32 notifies one or more staff members 72 of the event information newly acquired in step S120. More specifically, based on the event information, broadcast notification is performed to simultaneously notify the staff terminals 34 of all logged-in staff members 72 who belong to the unit in charge of the resident 70 . Note that FIG. 11 shows only the processing of one staff terminal 34 used by one staff member 72 among the plurality of staff terminals 34 .

(Steps S160, S170)
Each staff member 72 confirms the event that has occurred through the staff terminal 34 . 13A and 13B are examples of operation screens d1 and d2 for responding to an event notification (broadcast notification) displayed on the display unit 343 of the staff terminal 34. FIG. The operation screen d1 shown in the figure is a screen on which an event list is displayed. Events to be displayed can be scrolled up and down by flicking.

Areas a10 to a12 of the operation screen d1 correspond to event IDs 010 to 013 of the event list in FIG. Area a10 displays an icon indicating that event ID010 is a care call and that the event has been dealt with. Area a11 displays an icon indicating that event ID011 is a wake-up event and that the event has already been dealt with. Area a12 displays icons indicating wake-up event and bed-leaving event for event IDs 012 and 013, and indicates that they are not supported. Since these two events relate to the same resident 70 (Mr. C), they are collectively displayed in the same area. Also, since it is not supported, a thumbnail image (image i013) relating to the latest event (ID013) is displayed in the area a13. Text messages can be exchanged with other logged-in staff members 72 by operating the area a13. The staff member 72 clicks on the area a12 on the operation screen d1 to transition to the next operation screen d2 for confirming the contents.

(Step S170)
The staff member 72 confirms the details of the event using the operation screen d2 displayed on the staff terminal . On the operation screen d2, the name of the resident (Mr. C) who caused the occurrence (judgment) of the event and the name of the staff member (staff D) who uses the staff terminal 34 are displayed in an area a20. The area a21 displays the elapsed time from the occurrence time of the event. The elapsed time (“elapsed 1 minute”) shown in area a21 is the elapsed time (rounded down to the nearest minute) after the occurrence of the latest event is determined. In the area a21, a thumbnail image (still image) of the captured image at the time of the event (getting out of bed) determination is displayed. When the staff member 72 wants to check the situation of the resident 70 who caused the event of getting out of bed or getting up because the thumbnail image is not enough information, the staff member 72 can click the "talk" button or the "view" button in the lower areas a23 and a24. to operate. By operating the “Talk” button, the user can talk with the resident 70 (Mr. C) through the voice input/output unit 315 . By operating the "view" button, a display request is transmitted to the watching device 32, and in response to this, a live image (real-time captured image (moving image)) captured by the camera 313 is streamed on the operation screen d2. You can watch it by playback. When the "view" button is operated, as shown in the video viewing column of the event list in FIG. say). At this time, in association with the event, the video viewing time and the number of calls/call time via the "talk" button may be recorded.

The staff member 72 (for example, staff member D) takes the initiative in taking charge of getting up and leaving the bed (ID012, 013) displayed by operating the "correspondence" button (hereinafter also referred to as "response request") in the area a22. hope to If not, the back button (triangular icon) in the bottom column is operated to return to the previous operation screen d1 showing the event list. While a certain staff member 72 is displaying the operation screen d2 shown in FIG. 13 and confirming the state of the event, the other staff member 72 is prohibited by the control of the watching device 32 . For example, even if another staff member 72 selects the same event (ID013) while a certain staff member 72 is checking the event status of the resident 70 (Mr. C), the operation screen d1 of the other staff member 72 shows , and the characters "checking status" are displayed, and the "corresponding" button is not displayed or cannot be selected even if the operation screen d2 is displayed.

(Steps S180, S190)
Staff D operates the "correspond" button (depresses the corresponding button) when he or she wishes to take the initiative in taking charge of the event. The staff terminal 34 transmits a charge request for the selected event to the watching device 32 in response to the operation of the "correspond" button by the staff D who is the terminal user. In response, the watching device 32 returns an approval notice. Upon approval, the staff member D, who has sent the charge request, becomes the person in charge of the event, checks the status of the event through the staff terminal 34, and rushes to the event (visiting the room) if necessary.

(Step S200)
The watching device 32 updates the event list according to the process of step S180. Specifically, the status of the event list (ID012 to 013: getting out of bed, etc.) is changed to handled. In the present embodiment, the event selected by the staff 72 and displayed on the operation screen d2 is changed to "handled" in response to the operation of the above-described "handle" button. That is, by operating the "Response" button, the response status of "Responded", which is information indicating confirmation, is input, and it is assumed that the staff member 72 who operated the button has responded, and the date and time of response is recorded. do. More specifically, in the event list of FIG. 12, the time when the process of step S180 or S190 was performed is recorded in the corresponding date/time column. In this case, by confirming the thumbnail image on the operation screen d2 or talking with the resident 70, the response may be terminated without rushing to respond. Note that the response date and time is not limited to this, and is the time when the staff 72 decides to visit the room of the resident 70 who caused an event such as a fall, a fall, a nurse call, etc. , may be recorded in the corresponding date and time column. Further, as another example, the correspondence result may be entered through another operation screen to complete the correspondence, and the input time may be recorded in the correspondence date and time column. In addition, when the event list is updated, the watching device 32 broadcasts the updated event list to all logged-in staff members.

(Step S210)
Here, an example of a case in which rushing is performed will be described. A staff member 72 in charge of the event visits the resident 70 who caused the event as a rush response.

(Step S220)
By operating the pause switch 316 or by detecting a third party other than the resident 70 based on the image captured by the camera 313, the detection unit 31 (event determination unit 31a) of the living room detects a plurality of By detecting the presence of a person, it is determined that the staff member 72 has visited (entered) the room. At this time, if the room where the event occurred is visited within a predetermined period of time (for example, within 10 to 15 minutes) after the request for response to the event (S180), the staff member who made the request for response It is assumed that 72 (Staff D) visited the room. In addition, when using an NFC reading terminal placed at the entrance of the living room as the temporary stop switch 316, the staff member 72 holds up an IC card in which ID data is recorded to the reading terminal, thereby allowing the visit to the room to be terminated. You may make it determine whether it happened and which staff member 72 visited the room.

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

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

(Step S250)
The staff member 72 logs out by operating a button (not shown) of "end of work" on the staff terminal 34 at the end of work. The logout time is recorded in the storage unit 323 as shift information.

(Operation log data, correspondence information log data, and usage status)
As described above, the monitoring device 32 is connected to each device (also referred to as a monitoring support sensor) of the nursing care facility 900.
), and generates operation log data and corresponding information log data from this information, and stores them in the storage unit 323 . Again, refer to FIG.

(Operation log data)
The operation log data is data representing the operating state of each device of the monitoring support system 30 . As shown in FIG. 3A, the operation log data includes event notification (x1) and login/logout (x2).

x1: 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 of the resident 70 detected by monitoring support sensors such as 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.

x2: Login/logout is performed by the staff terminal 34 corresponding to steps S100 and S250 in FIG. 11 described above. 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 storage unit 323 as shift information.

(correspondence information log data)
The response information log data is information related to response to an event requiring care of the resident by the staff 72 using the watching support system 30 . As shown in FIG. 3B, the correspondence information log data includes correspondence button pressing information (y1), pause signal (y2), and room visit information (y3).

y1: Corresponding button pressing information corresponds to step S180 in FIG. The response button pressing information is a "response request" of the staff member 72, and is recorded in the event list in association with the event information.

y2: A pause signal is output in response to the operation of the pause switch 316 and recorded in the event list in association with the event information.

y3: Room visit information corresponds to step S220 in FIG. 11 described above. The image captured by the camera 313 or the operation of the temporary stop switch 316 records that the staff member 72 who sent the response request for the event has visited the room as the room visit information in the event list.

(Utilization status)
The analysis unit 112 of the information processing device 10 analyzes at least one of the usage situations z1 to z3 shown in FIG. At least one of z1 to z8 is calculated (quantified) and its change is analyzed.

z1 (rate of room visits due to notification): In response to an event notification, the number of visits a by the staff 72 to the resident's room related to the notification is defined as the number of event notification times b (step S150 in FIG. 11). Calculated by dividing by Room visit rate z1=Room visit count a/notice count b. Further, the analysis unit 112 may make an alert determination when the room visit rate z1 is outside a predetermined range, such as when the room visit rate z1 is extremely high. This is because the Live video function and the call function (corresponding to areas a23 and a24 of the operation screen d2 in FIG. 13) may not be fully used. In addition, if the monthly transition of the room visit rate z1, that is, the monthly transition comparing the room visit rate (per day) for this month and last month, if a decrease of a certain value or more occurs continuously , may be alerted.

z2 (event notification response rate): The number of times c that the staff 72 presses the response button in response to the event notification (corresponding to the requests in charge of steps S150 and S180 in FIG. 11) is divided by the number of event notification times b. Calculated by Correspondence rate z2=the number of presses c/the number of notifications b. Further, the analysis unit 112 may make an alert determination outside the predetermined range, such as when the correspondence rate z2 is extremely high. This is because there is a possibility that the corresponding button is pressed formally (perfunctory) without confirming the content of the event. In addition, if the monthly transition of the response rate z2, that is, the monthly transition comparing the room visit rate (per day) for this month and last month, if a decrease of a certain value or more occurs continuously, An alert judgment may be made. Note that the events used to calculate the response rate z2 may be calculated from all events including the care call event, or may be calculated from events other than the care call event.

z3 (care-call notification response rate): Calculates the response rate based on care-call events among events. Correspondence rate z3=number of times c of pressing/number of times of care call notification d. The calculation method and alert determination are the same as for the response rate z2, except that the type of event is limited to a specific care call. Note that the care call unit 314 may be operated continuously (continuously), and if the time interval between the preceding and following care calls is within a predetermined time (for example, within 1 second), the second and subsequent care calls are removed. Counting is preferred. This removal process can be performed on the detection unit 31 side (for example, the process of step S120).

z4 (Live video function usage rate): This is calculated by dividing the number of times e of viewing the Live video function by the number of times b of notification of the event when confirming the event details in step S170 of FIG. Usage rate z4=number of times of use e/number of times of notification b.

z5 (average moving image confirmation time): The average value of the moving image viewing time per time when the Live moving image function is used.

z6 (notification effective utilization rate): This is calculated from the number of event notifications b, response rate z2, and room visit rate z1. Utilization rate z6=number of notifications b*response rate z2*room visit rate z1. Regarding the utilization rate z4, the confirmation time z5, and the utilization rate z6, similarly to the room visit rate z1 and the response rate z2, when the numerical values are out of the predetermined range, or when the monthly transition continues outside the predetermined range An alert determination may be made.

z7 (decrease rate of number of visits to room): This uses the number of visits a itself. The analysis unit 112 calculates the transition of the monthly rate of decrease by dividing the number of visits to the room a in this month by the number of visits to the room a in January immediately after the introduction. The rate of decrease in the number of office visits is an index that indicates the efficiency of operations. For example, by omitting the visit to the room after confirming the situation using the Live video function and the call function, the time can be allocated to other tasks. If the rate of decrease is lower than a predetermined range (if the number of visits to the room remains high), an alert determination may be made. In this case, it can be inferred that the monitoring service is not effectively utilized.

z8 (working hours increase/decrease rate): The analysis unit 112 calculates the total working hours of the staff 72 based on the shift information. This working time may be normalized by the number of staff members 72 or residents 70 working at nursing care facility 900 . The analysis unit 112 calculates the transition of the monthly decrease rate by dividing the current month's working hours f by the January working hours f immediately after the introduction. The rate of increase/decrease in working hours is an index that indicates the efficiency of work. For example, if the working hours have increased, or if there is no change from immediately after introduction, an alert determination may be made. In this case, it can be inferred that the monitoring service is not effectively utilized. Regarding the usage states z1 to z8, the analysis unit 112 analyzed changes over time in monthly transitions, but instead of this, it is possible to analyze changes over time on a weekly, quarterly, or yearly basis. can be

(Analysis processing of usage status)
Next, with reference to FIG. 14, a utilization status analysis process based on the above-described operation log data and correspondence information log data will be described. FIG. 14 is a flow chart showing the analysis processing of the usage status.

(Steps S410, S420)
The acquisition unit 111 acquires operation log data and corresponding information log data (see FIGS. 3A and 3B) from the monitoring support system 30 of each nursing care facility 900 . Control unit 110 stores the acquired operation log data and correspondence information log data in storage unit 130 .

(Step S430)
The control unit 110 determines whether or not it is time to analyze. For example, every predetermined day such as every month, or when there is a request from the terminal device 20 (employee 76), it is determined that the analysis will be performed (YES), the process proceeds to step S440, Otherwise (NO), the processing from step S410 is repeated.

(Step S440)
The analysis unit 112 analyzes the utilization status of one or a plurality of nursing care facilities 900 at the analysis timing. Specifically, the analysis unit 112 analyzes the utilization states z1 to z8 in FIG. 3(c).

(Step S450)
The analysis unit 112 determines whether or not the time-dependent change in usage is outside a predetermined range. For example, it is determined whether or not the monthly transition in comparison with the immediately preceding month or immediately after introduction is outside a predetermined range (utilization statuses z1 to z8). Alternatively, it is determined whether or not the decrease outside the predetermined range has continued in the monthly transition (utilization statuses z1 to z6). If it is not outside the predetermined range (NO), the process proceeds to step S460. On the other hand, if it is outside the predetermined range (YES), the process proceeds to step S470.

(Step S460)
The output unit 113 outputs the analysis result of the usage status. For example, the output unit 113 transmits analysis results to the terminal device 20 . The employee 76 arranges and displays a plurality of usage status data of each nursing care facility 900 on the dashboard displayed on the display unit 230 of the terminal device 20 . For example, the service provider (employee 76, etc.) can grasp the degree of utilization of the monitoring support service in a specific nursing care facility 900 by referring to the dashboard.

(Step S470)
As in step S460, the analysis result of the usage status is output. Furthermore, the analysis unit 112 includes an alert, that is, the low utilization of the monitoring support service of the monitoring support system 30 and a high possibility of withdrawal in the analysis result. The output unit 113 outputs this alert together with the analysis result. As an example of outputting an alert, it is possible to output a response method as a report together, and highlight the corresponding item (item of usage status) with color, marking, etc. so that it can be distinguished from other items. may In this case, the analysis results of the utilization status of the plurality of nursing care facilities 900 may be displayed as a list. The service provider can read through the dashboard displayed on the display unit 230 that the degree of utilization of the monitoring support system has decreased and that some kind of trouble has occurred. Then, the possibility of withdrawal from the monitoring support service of the nursing care facility 900 can be grasped, and measures can be taken to prevent withdrawal according to the cause.

As described above, the information processing apparatus according to the present embodiment includes a first acquisition unit that acquires the operation log data of the monitoring support sensor, and a second acquisition unit that acquires staff response information log data in response to the notification based on the monitoring support sensor an acquisition unit, an analysis unit that analyzes the usage status of the monitoring support sensor based on the operation log data and the correspondence information log data, and an output unit that outputs the analysis result of the analysis unit. As a result, it is possible to provide useful information for grasping in advance the user's dissatisfaction with the monitoring support sensor, that is, information useful for grasping in advance the sign of withdrawal due to the user's dissatisfaction with the monitoring support service, and by extension, the monitoring support. It is possible to prevent withdrawal from the service.
