Life activity display device

[0001] The present specification discloses a daily activity display device.

[0002] Conventionally, there are known devices that display a user's daily activities (lifestyle data) for multiple days. For example, Patent Literature 1 discloses a device that displays the daily life data for each day in a vertical line with the horizontal axis representing time, with the wake-up time for each day at the left end of the time axis.

[0003] International Publication No. 2012 / 008264

[0004] In order to accurately grasp a user's daily activities from lifestyle data for multiple days, it is important to make it easy to compare lifestyle data for multiple days, and there is still room for improvement.

[0005] A main object of the present disclosure is to provide a daily activity display device that displays daily activity records for multiple days and allows easy comparison of activity events that occurred on each day.

[0006] The present disclosure has adopted the following means to achieve the above-mentioned main object.

[0007] The first daily living behavior display device of the present disclosure is a daily living behavior display device that displays a user's daily living behavior record, and displays the daily living behavior record for multiple days in chronological order, starting from the start time of a meal, the time of returning home from an outing, the start time of a bath, or the start time of using the toilet, as the occurrence time of a specific behavior event that occurred on each of the multiple days, among behavior events included in the daily living behavior record for multiple days.

[0008] In the first daily activity display device of the present disclosure, daily activity records for multiple days are displayed in chronological order starting from the specific behavioral events, starting from the start time of a meal, the time of returning home from an outing, the start time of a bath, or the start time of using the toilet, as the occurrence time of the specific behavioral event for each day. This allows the user to easily compare the elapsed time from the occurrence of each behavioral event (eating, returning home from an outing, bathing, toilet) for multiple days, which is useful for understanding daily activities.

[0009] The second daily living behavior display device of the present disclosure is a daily living behavior display device that displays a user's daily living behavior records, and displays the daily living behavior records for multiple days in chronological order by day with the time on the time axis aligned, starting from the time of occurrence of a specific behavior event that occurred on any of the multiple days among behavior events included in the daily living behavior records for multiple days.

[0010] In the second living activity display device of the present disclosure, the living activity records for multiple days are displayed in a list in chronological order starting from the occurrence time of a specific behavioral event that occurred on any of the days, with the time on the time axis aligned, allowing the user to easily compare the occurrence times of each behavioral event starting from a specific behavioral event on any of the days across multiple days, which is useful for understanding living activities.

[0012] Next, embodiments of the present disclosure will be described with reference to the drawings.

[0013] FIG. 1 is a schematic diagram of a behavior monitoring system 10. As shown in FIG. 1, the behavior monitoring system 10 includes a management server 20 that manages the entire system, and monitoring devices 30 that are installed in each of residences A to C where a monitoring target person lives and monitor the monitoring target person. Residences A to C are, for example, residences where elderly people or people requiring care live alone, and, as shown in FIG. 2, each residence may have a living room (L), dining room (D), kitchen (K), bedroom, washroom, bathroom, toilet, and entrance hall. The behavior monitoring system 10 can be used, for example, to monitor the behavior of elderly people or people requiring care as monitoring targets on behalf of caregivers and to detect abnormalities in their behavior early on.

[0014] The monitoring device 30 comprises a control unit 31, a communication unit 32, an operation display unit 33 (living activity display device), a speaker (not shown), and sensors 40. The control unit 31 is configured as a microprocessor centered around a CPU, and in addition to the CPU, comprises ROM, RAM, etc. The operation display unit 33 and speaker output various information from the management server 20 by display or sound. The operation display unit 33 is configured as a touch panel display that allows the operator to input operations.

[0015] The sensors 40 are sensors for detecting where and what the monitored person living in the residence is doing, and as shown in Figure 2, include human presence sensors 41, 42, 43, 44, 45, and 46 installed in each room, a sleep sensor 47 installed in the bedroom, a toilet faucet sensor 48 installed in the toilet room, and a door sensor 49 installed at the front door.

[0016] The motion sensors 41 to 46 are sensors that detect people within their detection areas without contact, and are configured as, for example, infrared sensors that sense infrared rays and convert them into electrical signals. Motion sensors 41, 42, and 43 are installed in the living room, dining room, and kitchen of the living / dining / kitchen room, respectively. Motion sensor 44 is installed in the bedroom, and motion sensor 45 is installed in the bathroom. Motion sensor 46 is installed in the toilet.

[0017] The sleep sensor 47 is, for example, a sheet-type biosensor installed under a bed mattress in a bedroom, and acquires biometric information such as the pulse and breathing of the person sleeping in the bed. The toilet faucet sensor 48 detects the operation of the flush lever or flush switch that commands the toilet to flush, and in this embodiment, it distinguishes between the large flush operation and the small flush operation. The door sensor 49 detects the opening and closing of the front door, and is configured, for example, as a magnetic opening and closing sensor having a permanent magnet fixed to the door side and a magnetic sensor fixed to the frame side.

[0018] The management server 20 comprises a processing unit 21, a communication unit 22, and a storage unit 23. The processing unit 21 is configured as a microprocessor centered around a CPU, and in addition to the CPU, comprises a ROM, a RAM, etc. The communication unit 22 of the management server 20 is connected to the communication units 32 of each monitoring device 30 and the communication unit 52 of the mobile terminal 50 via the network 11, and exchanges data and signals with each other. The storage unit 23 is configured with a hard disk drive (HDD), a solid state drive (SSD), etc., and receives data measured by each monitoring device 30 and stores the data for a certain period of time.

[0019] Next, the operation of the behavior monitoring system 10 configured as described above will be described. That is, the operation of the monitoring device 30 and the operation of the management server 20 will be described.

[0020] The data measurement process is a process of measuring (collecting) the location of a person being monitored using sensors installed in each room of the residence. Fig. 3 is a flowchart showing an example of the data measurement process executed by the control unit 31 of each monitoring device 30. This process is repeatedly executed at predetermined time intervals.

[0021] When the data measurement process is executed, the control unit 31 of the monitoring device 30 first determines whether or not there is a reaction from the living room motion sensor 41 installed in the living room (step S100). If the control unit 31 determines that there is a reaction from the living room motion sensor 41, it determines that the person to be monitored is present in the living room (step S102), transmits the determination result to the management server 20 as measurement data (step S136), and ends the data measurement process.

[0022] If the control unit 31 determines in step S100 that there is no reaction from the living room motion sensor 41, it next determines whether there is a reaction from the dining room motion sensor 42 installed in the dining room (step S104). If the control unit 31 determines that there is a reaction from the dining room motion sensor 41, it determines that the person to be monitored is present in the dining room (step S106), transmits the determination result to the management server 20 as measurement data (step S136), and ends the data measurement process.

[0023] If the control unit 31 determines in step S104 that there is no reaction from the dining room motion sensor 42, it then determines whether there is a reaction from the kitchen motion sensor 43 provided in the kitchen (step S108). If the control unit 31 determines that there is a reaction from the kitchen motion sensor 43, it determines that the person to be monitored is present in the kitchen (step S110), transmits the determination result to the management server 20 as measurement data (step S136), and ends the data measurement process.

[0024] If the control unit 31 determines in step S108 that there is no reaction from the kitchen motion sensor 43, it then determines whether there is a reaction from the bedroom motion sensor 44 installed in the bedroom (step S112). If the control unit 31 determines that there is a reaction from the bedroom motion sensor 44, it determines that the person to be monitored is present in the bedroom (step S114). Then, the control unit 31 acquires a detection signal from the sleep sensor 47 (step S116), transmits the determination result and the detection signal from the sleep sensor 47 as measurement data to the management server 20 (step S136), and ends the data measurement process.

[0025] If the control unit 31 determines in step S112 that there is no reaction from the bedroom motion sensor 44, it then determines whether there is a reaction from the bathroom motion sensor 45 provided in the bathroom (step S118). If the control unit 31 determines that there is a reaction from the bathroom motion sensor 45, it determines that the person to be monitored is present in the bathroom (step S120), transmits the determination result to the management server 20 as measurement data (step S136), and ends the data measurement process.

[0026] If the control unit 31 determines in step S118 that there is no reaction from the bathroom motion sensor 45, it next determines whether there is a reaction from the toilet motion sensor 46 provided in the toilet (step S122). If the control unit 31 determines that there is a reaction from the toilet motion sensor 46, it determines that the person to be monitored is present in the toilet (step S124). Then, the control unit 31 acquires a detection signal from the toilet faucet sensor 48 (step S126), transmits the determination result and the detection signal from the toilet faucet sensor 48 as measurement data to the management server 20 (step S136), and ends the data measurement process.

[0027] If the control unit 31 determines in step S122 that the toilet motion sensor 46 has not responded, it then determines whether the front door sensor 49 installed on the front door has responded (step S128). If the control unit 31 determines that the front door sensor 49 has responded, it determines in step S134 (described later) whether the monitored person has been determined to be at home (step S130). If the control unit 31 determines that the monitored person has been determined to be at home, it determines that the monitored person has left the house (step S132), transmits the determination result to the management server 20 as measurement data (step S136), and terminates the data measurement process. On the other hand, if the control unit 31 determines that the monitored person has not been determined to be at home (i.e., has been determined to be out), it determines that the monitored person has returned home, i.e., is at home (step S134), transmits the determination result to the management server 20 as measurement data (step S136), and terminates the data measurement process.

[0028] Next, a description will be given of the operation of the management server 20. Fig. 4 is a flowchart showing an example of a measurement data reception process executed by the processing unit 21 of the management server 20. This process is repeatedly executed at predetermined time intervals.

[0029] When the measurement data reception process is executed, the processing unit 21 of the management server 20 first determines whether measurement data has been received from the monitoring device 30 (step S200). If the processing unit 21 determines in step S200 that measurement data has not been received, the process proceeds to step S206. On the other hand, if the processing unit 21 determines that measurement data has been received, the processing unit 21 accesses a time server via the Internet to obtain time information including the current date, time (hour / minute / second), and day of the week (step S202), associates the obtained time information with the measurement data, and stores it in the storage unit 23 (step S204), and then proceeds to step S206. Note that the time information may be obtained by reading the current time from an RTC (real-time clock).

[0030] Next, the processing unit 21 determines whether a certain period of measurement data (e.g., one day's worth) has been accumulated in the storage unit 23 (step S206). If the processing unit 21 determines that the certain period of measurement data has not been accumulated, the processing unit 21 proceeds to step S212. On the other hand, if the processing unit 21 determines that the certain period of measurement data has been accumulated, the processing unit 21 extracts predetermined behavioral events from the certain period of measurement data (step S208) and registers the extracted behavioral events in the storage unit 23 together with their occurrence times (step S210). In this embodiment, behavioral events include waking up, going to bed, eating, small bowel movements, large bowel movements, bathing, etc. For example, waking up can be determined based on the sleep sensor 47 detecting a change from a sleeping state to a waking state while the user is in the bedroom. Going to bed can be determined based on the sleep sensor 47 detecting a change from a waking state to a sleeping state while the user is in the bedroom. A meal can be determined based on the determination that the user has moved from the kitchen to the dining room and then stayed in the dining room for a certain period of time or longer. Bathing can be determined based on whether a person has stayed in the bathroom for a certain period of time or more. Small excretion can be determined based on whether a small flush operation is detected by the toilet faucet sensor 48 while the person is in the toilet. Large excretion can be determined based on whether a large flush operation is detected by the toilet faucet sensor 48 while the person is in the toilet. Small excretion may be determined based on whether a person has stayed in the toilet for less than a certain period of time, and large excretion may be determined based on whether a person has stayed in the toilet for more than a certain period of time. In this case, the faucet sensor 48 may be omitted.

[0031] Next, the processing unit 21 determines whether or not a request to transmit an activity record has been received from the monitoring device 30 (operation display unit 33) (step S212). If the processing unit 21 determines that a request to transmit an activity record has not been received, it terminates the measurement data registration process. On the other hand, if the processing unit 21 determines that a request to transmit an activity record has been received, it transmits the activity events stored in the storage unit 23 and their occurrence times as a daily activity record to the monitoring device 30 that has received the transmission request (step S214), and terminates the measurement data registration process.

[0032] Next, the operation of the monitoring device 30 that has received a behavioral event will be described. Fig. 5 is a flowchart showing an example of an behavior record display process executed by the control unit 31 of the monitoring device 30. This process is executed when the user operates the operation display unit 33 to instruct display of the daily activities of the monitored person.

[0033] When the behavior record display process is executed, the control unit 31 displays a display setting screen on the operation display unit 33 (step S300). Next, the control unit 31 accepts the selection of a specific behavior event on the display setting screen (step S302) and accepts the settings of a display period and a display time width (step S304). Here, the specific behavior event is a behavior event that serves as the starting point for displaying daily behavior events arranged in chronological order. FIGS. 6 and 7 are explanatory diagrams showing an example of the display setting screen. In this embodiment, as shown in FIG. 6, specific behavior events include waking up, going to the toilet, eating, returning home from an outing, and bathing. The user selects a specific behavior event by selecting one of these multiple behavior events and pressing the "Next" button. In this embodiment, meals are categorized by the time period in which they occur: breakfast (e.g., 7:00-10:00), lunch (e.g., 11:00-14:00), and dinner (e.g., 17:00-20:00). The user selects a meal by choosing one from breakfast, lunch, and dinner. The display period and display time width are set by inputting the start and end dates of the display period as numerical values, and by inputting a numerical value between 1 and 24 for the display time width, and then pressing the "OK" button.

[0034] Next, the control unit 31 acquires from the management server 20 behavioral events within a display time range starting from the occurrence time of a specific behavioral event for each day among the daily behavior records within the display period (step S306). For example, if waking up is selected as the specific behavioral event, May 5th to May 8th are set as the display period, and 15 hours are set as the display time range, the control unit 31 acquires behavioral events that occurred between the wake-up time for each day of May 5th to May 8th, setting the wake-up time as the start point and 15 hours after the wake-up time as the end point. The control unit 31 then arranges the acquired behavioral events in chronological order by day and displays a list on the operation display unit 33 according to the elapsed time from each specific behavioral event for each day (step S308).

[0035] FIG. 8 is an explanatory diagram showing an example of a display of several days' worth of daily activity records, starting from the wake-up time. As shown in the figure, the daily activity records displayed on the operation display unit 33 include information on whether the user is at home, meals, toileting, bathing, sleep, and sleep status (e.g., sleep depth level in non-REM sleep and REM sleep). When waking up is selected as a specific behavioral event, the daily activity records are displayed in a chronological order, starting from the wake-up time of each day and based on the elapsed time from that start point. FIG. 9 is an explanatory diagram showing an example of a display of several days' worth of daily activity records, starting from the return home time from going out. When returning home from going out is selected as a specific behavioral event, the daily activity records are displayed in a chronological order, starting from the return home time of each day and based on the elapsed time from that start point. In this way, the daily activity records for several days are displayed as the elapsed time from the specific behavioral event, making it easier for the user to understand daily activity patterns from the records for several days.

[0036] After displaying the list, the control unit 31 determines whether an end operation has been performed (step S310). If the control unit 31 determines that an end operation has not been performed, it determines whether a return operation has been performed (step S312). If the control unit 31 determines that a return operation has not been performed, it returns to step S310, and if it determines that a return operation has been performed, it returns to step S300. If the control unit 31 determines that an end operation has been performed in step S310, it ends the action record display process.

[0037] Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure described in the claims will be described. That is, the operation display unit 33 of the present embodiment is an example of the behavior record display device of the present disclosure.

[0038] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be embodied in various forms as long as they fall within the technical scope of the present disclosure.

[0039] For example, in the above-described embodiment, the control unit 31 arranges behavioral events occurring within the display time range by day in chronological order, starting from the occurrence time of each specific behavioral event on each day of the specified display period, and displays a list of the elapsed time from each specific behavioral event on each day. However, the control unit 31 may also arrange behavioral events occurring within the display time range by day in chronological order, starting from the occurrence time of a specific behavioral event occurring on any day of the specified display period, and display the list with the time on the time axis aligned. In this case, the control unit 31 may execute the behavior record display process illustrated in FIG. 10 . The behavior record display process illustrated in FIG. 10 will be described below. Note that the same steps as those in FIG. 5 among the steps in the behavior record display process in FIG. 10 are assigned the same step numbers, and their descriptions will be omitted to avoid duplication.

[0040] In the behavior record display process of FIG. 10 , the control unit 31 accepts the selection of a specific behavior event (step S302), accepts the setting of the display period and display time width (step S304), and accepts the selection of a time to be used as the display start point among the occurrence times of specific behavior events that occurred on each day of the display period (step S400). FIG. 11 is an explanatory diagram showing an example of a display setting screen. As shown in the figure, the display start point times include the earliest time, latest time, average time, median time, and the time of a specific day specified within the display period. The user selects a time by selecting one of these multiple times and pressing the "OK" button. Note that the specific day is selected by entering the numerical value of the month and day to be specified within the display period.

[0041] Next, the control unit 31 acquires behavioral events for the display time range starting from the selected time from the management server 20 (step S402).The control unit 31 then arranges the acquired behavioral events in chronological order by day, aligns the time on the time axis for each day, and displays a list of the events on the operation display unit 33 (step S404), and proceeds to step S310.

[0042] FIG. 12 is an explanatory diagram showing an example of displaying daily activity records for several days according to another embodiment. When waking up is selected as a specific behavioral event and a specific day (May 8) is selected as the display start time, the daily activity records are displayed in a list format aligned on the time axis for each day, starting from the occurrence time of the specific behavioral event on the specific day. Therefore, for days on which a specific behavioral event occurred later than the occurrence time of the specific behavioral event on the specific day, the remaining time of the specific behavioral event is displayed, and for days on which a specific behavioral event occurred earlier than the occurrence time of the specific behavioral event on the specific day, the specific behavioral event is not displayed. Because daily variations in the behavioral events are displayed in a list format aligned on the time axis, it is easy to understand the temporal variations in the behavioral events from day to day. Furthermore, because the occurrence time of a specific behavioral event is used as the starting point, this can be useful for understanding behavioral patterns based on the specific behavioral event.

[0043] In the above-described embodiment, the management server 20 transmits the daily activity record of the monitoring subject to the monitoring device 30, and the monitoring device 30 executes an activity record display process based on the received daily activity record of the monitoring subject, thereby displaying the activity record on the operation display unit 33. However, the management server 20 may transmit the daily activity record to a display terminal (e.g., a tablet terminal) other than the monitoring device 30, and the display terminal may display the activity record by executing a process similar to the above-described activity record display process based on the received daily activity record.

[0044] In the first activity record display device of the present disclosure described above, daily activity records for multiple days are displayed in chronological order starting from the occurrence time of a specific activity event for each day, such as the start time of a meal, the time of returning home from an outing, the start time of a bath, or the start time of using the toilet. This allows the user to easily compare the elapsed time from the occurrence of each activity event (eating, returning home from an outing, bathing, toilet) for each day across multiple days, which can be useful in understanding daily activities.

[0045] In addition, in the second behavior record display device of the present disclosure, daily behavior records for multiple days are displayed in a list in chronological order starting from the occurrence time of a specific behavior event that occurred on any of the days, with the time on the time axis aligned, so that the user can easily compare the occurrence times of each behavior event starting from a specific behavior event on any of the days across multiple days, which is useful for understanding daily behavior.

[0046] In the second behavior record display device of the present disclosure, the starting point may be the earliest occurrence time of the specific behavioral events that occurred on each of the plurality of days, the latest occurrence time of the specific behavioral events that occurred on each of the plurality of days, the average time or median time of the occurrence times of the specific behavioral events that occurred on each of the plurality of days, or the occurrence time of the specific behavioral events that occurred on a specific day designated by the user. In this way, the user can have an opportunity to understand their daily behavior patterns from various perspectives.

[0047] In the second behavioral record display device of the present disclosure, the occurrence time of the specific behavioral event may be the time of waking up, the time of starting a meal, the time of returning home from going out, the time of starting to take a bath, or the time of starting to use the toilet, thereby providing the user with an opportunity to understand their daily behavior patterns from various perspectives.

[0048] The present disclosure is applicable to the manufacturing industry of behavior record display devices.
