Description

Health and behavior monitoring system

This disclosure relates to a health and behavior monitoring system.

　Traditionally, monitoring systems capable of monitoring the physical condition of a monitored person are known. For example, the monitoring system of Patent Document 1 is equipped with a sensor device capable of detecting biological information such as the body temperature, posture, heart rate, and respiratory rate of the monitored person, and is capable of monitoring the physical condition of the monitored person based on the biological information detected by the sensor device.

Patent No. 6382433

Incidentally, when the person being monitored is, for example, a child at a nursery school or an elderly person residing in a nursing home, it is desirable to monitor not only the person's physical condition but also their behavior in order to ensure their health and safety. However, in the monitoring system of Patent Document 1, the sensor device can only detect the biometric information of the person being monitored, and therefore cannot monitor the person's whereabouts or other behavior.

The purpose of this disclosure is to provide a health and behavior monitoring system that can monitor the behavior of a person being monitored in addition to their health condition.

The present disclosure relates to a health and behavior monitoring system that includes a server device and a terminal device that can communicate with each other, and a sensor device that can communicate with at least the server device, and that can monitor the health and behavior of one or more monitored persons, and includes a detection unit, a processing unit, a display information generation unit, and a display unit. The sensor device can be attached to the body of each of the one or more monitored persons. The detection unit can detect the heart rate of the monitored person as biometric information, and can detect the location of the monitored person as location information. The processing unit can process the biometric information and/or location information detected by the detection unit. The display information generation unit can generate display information based on the biometric information and/or location information detected by the detection unit or processed by the processing unit.

The display unit can display the display information generated by the display information generation unit. Therefore, the monitor can monitor the behavior of the person being monitored as well as the physical condition of the person being monitored by checking the display information displayed on the display unit.

The above and other objects, features and advantages of the present disclosure will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:

Below, a health and behavior monitoring system according to one embodiment will be explained with reference to the drawings.

(One embodiment)
A health and behavior monitoring system according to one embodiment is shown in Fig. 1. The health and behavior monitoring system 1 includes a server device 20 and a terminal device 30 that can communicate with each other, and a sensor device 10 that can communicate with at least the server device 20, and can monitor the health and behavior of one or more monitoring subjects. The health and behavior monitoring system 1 includes a detection unit 12, a display information generation unit 22, a display information generation unit 32, and a display unit 33 (see Fig. 2). As shown in Figs. 1 and 2, the sensor device 10, the server device 20, and the terminal device 30 can communicate with each other via a network 2 such as an IP network.

In this embodiment, the subjects of monitoring are, for example, kindergarten children. The physical condition and behavior monitoring system 1 can monitor the physical condition and behavior of children mainly from the time they arrive at the kindergarten until they leave.

The sensor device 10 can be attached to the body of each of the children who are to be monitored, which are one or more subjects. The sensor device 10 is, for example, a wristwatch-type wearable device with a band, and is attached to the wrist or ankle of a child who attends the kindergarten. In this embodiment, it is assumed that the sensor device 10 will be attached to multiple children.

The sensor device 10 is a device capable of detecting the biometric information, positional information, and movement information of the child to which it is attached. The sensor device 10 has, for example, a processor as an arithmetic processing unit, storage such as ROM, RAM, and flash memory as a memory unit, and a buzzer, speaker, vibrator, LED, or display as an input/output interface. The memory unit stores various data and programs required for various processes in the arithmetic processing unit. The arithmetic processing unit of the sensor device 10 executes a program stored in a non-transient physical recording medium (memory unit). Execution of this program results in the execution of a method corresponding to the program.

As shown in FIG. 2, the sensor device 10 has, as functional units or functional modules, a processing unit 100, a sensor communication unit 11, a detection unit 12, an alert unit 13, a sensor memory unit 15, a battery 14, etc. In other words, the detection unit 12 and the alert unit 13 are provided in the sensor device 10. The processing unit 100 can perform data processing or calculations on various input information and output it to the sensor communication unit 11, the detection unit 12, the alert unit 13, the battery 14, the sensor memory unit 15, etc.

The sensor communication unit 11 has, for example, a SIM card module, and can communicate with the server device 20 and the terminal device 30 by connecting to the network 2 through a telephone line of a mobile phone company or the like. The sensor communication unit 11 also has, for example, a Bluetooth (registered trademark) module capable of short-range wireless communication, and can directly communicate with the terminal device 30 within a specified distance range.

The detection unit 12 has a heart rate detection unit 121, a body temperature detection unit 122, a blood oxygen concentration detection unit 123, a location information detection unit 124, and a motion detection unit 125. The heart rate detection unit 121 has an optical heart rate sensor using, for example, an LED and a photodiode, and can detect the heart rate (pulse rate) (beats per minute: bpm) of the child wearing the sensor device 10.

The body temperature detection unit 122 has, for example, a temperature sensor, and can detect the body temperature of the child wearing the sensor device 10. The blood oxygen concentration detection unit 123 has, for example, an optical blood oxygen concentration sensor using an LED and a photodiode, and can detect the blood oxygen concentration (blood oxygen saturation) of the child wearing the sensor device 10.

The location information detection unit 124 has a GPS module that uses the Global Positioning System (GPS), which is one of the Global Navigation Satellite Systems (GNSS), and can detect the location on Earth of a child wearing the sensor device 10 as location information.

The motion detection unit 125 has, for example, an acceleration sensor and an angular velocity sensor (gyro sensor), and can detect the acceleration and angular velocity (rotation) of the sensor device 10 and detect the movements, posture, and other motions of the child wearing the sensor device 10 as motion information. By detecting the motion information of the child using the motion detection unit 125, it is possible to estimate the child's posture (face down or face up, for example), whether the child has fallen, whether the child is sleeping, etc. The motion information detected by the motion detection unit 125 can also be used to count the number of steps the child takes and calculate the calories burned.

Here, the position information detection unit 124 corrects the detected position information based on the acceleration and angular velocity of the sensor device 10 detected by the motion detection unit 125, and on information acquired by base station positioning technology, and is able to detect and calculate with high accuracy the position information of the child wearing the sensor device 10. In other words, the motion detection unit 125 can improve the accuracy of detection of position information by the position information detection unit 124.

In this way, the detection unit 12 can detect the heart rate, body temperature, and blood oxygen concentration of the child who is the subject of monitoring as biometric information using the heart rate detection unit 121, body temperature detection unit 122, and blood oxygen concentration detection unit 123, and can detect the child's location as location information using the location information detection unit 124. The detection unit 12 can also detect the child's movements, posture, and other actions as action information using the action detection unit 125. The sensor device 10 can process the detected biometric information, location information, and action information, for example, using the processing unit 100, and transmit it to the server device 20 or the terminal device 30 via the sensor communication unit 11.

<8> The detection unit 12 detects biological information every first predetermined period T1 using the heart rate detection unit 121, body temperature detection unit 122, and blood oxygen concentration detection unit 123, and detects position information every second predetermined period T2 using the position information detection unit 124. The initial values of the first predetermined period T1 and the second predetermined period T2 are, for example, one minute. Therefore, immediately after attaching the sensor device 10 to the child, the detection unit 12 detects the child's heart rate, body temperature, blood oxygen concentration, and position information every minute, that is, at one-minute intervals. Here, the initial values of the first predetermined period T1 and the second predetermined period T2 may be other than one minute, for example, 30 seconds, 2 minutes, etc., and can be changed to any value.

The detection unit 12 also detects the motion information every third predetermined period T3 using the motion detection unit 125. The third predetermined period T3 is set variably depending on the situation, for example, within the range of 0.625 ms (high frequency) to 1.28 s (low frequency). Here, the third predetermined period T3 may be a value outside the range of 0.625 ms to 1.28 s, and can be changed to any value.

The sensor memory unit 15 is, for example, a part of the memory unit of the sensor device 10, and can store biometric information, positional information, motion information, etc. detected by the detection unit 12 for each time (detection time). The sensor memory unit 15 can also store a first predetermined period T1, a second predetermined period T2, and a third predetermined period T3.

<2> The alert unit 13 has, for example, a buzzer, speaker, vibrator, LED, or display, and can output an alert (notification, warning) in the form of a beep from the buzzer, voice from the speaker, vibration from the vibrator, light from the LED, text, images, etc. from the display. The battery 14 is, for example, a rechargeable secondary battery such as a lithium ion secondary battery, and supplies power to the processing unit 100, sensor communication unit 11, detection unit 12, alert unit 13, sensor memory unit 15, etc.

At least a portion of the processing unit 100, the sensor communication unit 11, the detection unit 12, and the alert unit 13 is realized, for example, by a program stored in the storage unit of the sensor device 10.

The server device 20 is a computer device capable of processing biometric information, position information, motion information, etc., from the sensor device 10. The server device 20 has, for example, a processor as an arithmetic processing unit, storage such as ROM, RAM, HDD or SSD as a memory unit, and a keyboard, mouse, display, speaker, etc. as an input/output interface. The memory unit stores various data and programs required for various processes in the arithmetic processing unit. The arithmetic processing unit of the server device 20 executes a program stored in a non-transitive physical recording medium (memory unit).

Next, the functions of the health and behavior monitoring system 1 will be explained with reference to the drawings.

Figures 3 to 16 show the screens displayed on the display unit 33 of the terminal device 30.

On the "Dashboard" screen that is displayed by tapping or clicking on area AA00 shown in FIG. 3, the caregiver can check the general status of the biological information (physical condition) and location information (behavior) of the child wearing the sensor device 10. For example, area AA01 on the screen displays the name of the child whose biological information (physical condition) is abnormal and the alert content (content of the abnormality). For example, the alert content may display "bradycardia" when the heart rate is detected to be below a predetermined value (e.g., 60 bpm), "tachycardia" when the heart rate is detected to be above a predetermined value (120 bpm), "hypothermia" when the body temperature is detected to be below a predetermined value, "hyperthermia" when the body temperature is detected to be above a predetermined value, and "hypoxia" when the blood oxygen concentration is detected to be below a predetermined value. This allows the caregiver to check which child has an abnormality in their physical condition.

In area AA02 of the screen shown in Figure 3, an image G01 corresponding to the child is displayed superimposed on the map image at a position corresponding to the detected child's location information. This allows caregivers to easily visually confirm the child's whereabouts.

Area AA03 on the screen shown in Figure 3 displays the name of the child and information about the heart rate during the afternoon nap. For example, when the heart rate is below a predetermined value (e.g. 60 bpm), "below 60 bpm" is displayed; when the heart rate is above a predetermined value (e.g. 120 bpm), "above 120 bpm" is displayed; and when the heart rate is higher than 60 bpm and lower than 120 bpm, "normal" is displayed. This allows caregivers to check the physical condition (normal or abnormal) of the child's heart rate during the afternoon nap. Note that the criteria for normal or abnormal heart rate are not limited to the above criteria and can be changed to any criteria.

As mentioned above, the "Dashboard" screen shown in Figure 3 allows caregivers to simultaneously check the general status of children's biological information and location information on one screen, allowing them to simultaneously and easily monitor (check and understand) the children's physical condition and behavior.

In the "Nap Check" screen, which is displayed by tapping or clicking area AB00 shown in Figure 4, the caregiver can start nap monitoring (nap check) of the children by tapping or clicking the "Start Nap Monitoring" button (area AB01) at any time.

In area AB02 of the "Nap Check" screen shown in Figure 4, the state of the battery 14 of the sensor device 10 attached to the child and the connection and communication status can be checked. In the example of Figure 4, a mark M01 is displayed in a conspicuous color such as yellow to warn the child "B-chan" in the upper right corner of the icon, and a mark M02 below the icon indicates that the remaining charge of the battery 14 of the sensor device 10 attached to "B-chan" is below a specified value, and that a communication abnormality has occurred, preventing connection to the server device 20 or terminal device 30. This allows the caregiver to check the state of the sensor device 10 with an abnormality before starting nap monitoring, and take action such as replacing the sensor device 10.

In area AB02 in Figure 4, one or more children can be selected for nap monitoring (nap check). Figure 4 shows that "A-chan" and "B-chan" have been selected from "A-chan" through "H-chan."

In area AB03 shown in Figure 4, a "checker" (inspector) who visually checks the condition of the children during nap monitoring (nap check) can be selected from multiple childcare workers. Here, one or more "checkers" can be selected. In Figure 4, out of "Kobayashi Kenichi" teacher, "Yamamoto Sayaka" teacher, "Fukuyama Minato" teacher, "Inoue Honoka" teacher, and "Ichiyanagi Yuna" teacher, "Kobayashi Kenichi" teacher and "Ichiyanagi Yuna" teacher are shown to have been selected. In addition, childcare workers not displayed in area AB03 can be added by clicking the "Add new" button. By selecting multiple "checkers," checking the condition of the children can be shared among multiple people, reducing the burden on each "checker."

In area AB04 shown in FIG. 4, the scheduled time for nap monitoring can be selected. In FIG. 4, "60 minutes" is shown to be selected from among "60 minutes", "30 minutes", "45 minutes", and "90 minutes". In addition, by tapping or clicking the "Custom" button in area AB04, the scheduled time for nap monitoring can be set to any time other than "60 minutes", "30 minutes", "45 minutes", or "90 minutes".

In Figure 4, select the scheduled time for nap monitoring in area AB04, select "Verifier" in area AB03, select the children to be monitored in area AB02, and tap or click the "Start Nap Monitoring" button in area AB01 to begin nap monitoring for the selected children.

When the user taps or clicks on the calendar mark in area AB05 shown in FIG. 4, a calendar appears on the screen and any past date can be selected. When a user selects (tap or click) any date, information on the nap check for the selected past date is displayed on the screen. Information on the nap check for the past date is information on the heart rate of each child for each check time during the nap check (nap monitoring), and information on the child's condition such as "coughing" (check results, etc.), which is stored in the server memory unit 24 or the terminal memory unit 38.

Area AB06 shown in Figure 4 displays the name of the person in charge among the caregivers. Initially, area AB06 displays the name of the person in charge (caregiver) set in the initial settings, but this can be changed to a different caregiver by tapping or clicking area AB06.

Figure 5 shows the state after a predetermined time has passed, for example, when "60 minutes" is selected in area AB04 of Figure 4, teachers "Kobayashi Kenichi" and "Ichiyanagi Yuna" are selected in area AB03, and only "B-chan" is selected in area AB02, the "Start Nap Monitoring" button is tapped or clicked at 11:01, and "A-chan" is added as a target child at 11:09. In this embodiment, a nap check is carried out every predetermined period TT1. The initial value of the predetermined period TT1 is, for example, 15 minutes. In this embodiment, after nap monitoring begins, a nap check is carried out every 15 minutes, such as at 0 minutes, 15 minutes, 30 minutes, and 45 minutes past the hour. The caregiver can change the interval at which nap checks are carried out by tapping or clicking area AC02. For example, if the interval for performing a nap check is changed to 10 minutes, the predetermined period TT1 is changed to 10 minutes, and a nap check will be performed every 10 minutes, such as 0 minutes, 10 minutes, 20 minutes, 30 minutes, 40 minutes, and 50 minutes past the hour.

In Figure 5, the current time is 11:52:57, which indicates that the first through third checks have been completed in area AC01, with the fourth check scheduled for 12:00. Also, in the upper right corner of the icons for "A-chan" and "B-chan," who are the subjects of nap monitoring and are taking a nap (asleep), a mark M03 is displayed indicating that the subject children are taking a nap (asleep).

At any time, by tapping or clicking the "Start Nap" button displayed next to the name of a child who is not yet the subject of nap monitoring, the child can be added as a subject of nap monitoring. Also, if a child subject to nap monitoring wakes up, by tapping or clicking the "Wake Up" button displayed next to the child's name, nap monitoring can be ended for that child individually. Also, by tapping or clicking the "Wake Up All" button in area AC03, nap monitoring can be ended all at once for all children currently being monitored. When the nap monitoring is scheduled to end (the time that has elapsed since the start of the nap, as selected in area AB04 in Figure 4), a window will pop up to confirm whether or not to end nap monitoring.

As shown in Figure 6, when the scheduled time for the nap check arrives, a window for conducting the nap check pops up in area AD01. When this window pops up, all of the children who are the targets of nap monitoring ("A-chan" and "B-chan" in the example in Figure 6) are selected. Tapping or clicking on the icon of a selected child will deselect them.

Below the child's name in area AD01, the child's heart rate status is displayed. For example, if the heart rate has remained below a specified value (e.g. 60 bpm) for more than two minutes at that point in time, "60 bpm or less" is displayed; if the heart rate has remained above a specified value (e.g. 120 bpm) for more than two minutes, "120 bpm or more" is displayed; and if the heart rate is, for example, higher than 60 bpm and lower than 120 bpm, "normal heart rate" is displayed. Note that the criteria for normal or abnormal heart rate are not limited to the above criteria and can be changed to any criteria.

When the window for conducting the nap check pops up in area AD01, the caregiver (checker) visually checks each of the children to see if there are any abnormalities, such as lying face down. When multiple children are selected in the pop-up display in area AD01, tapping or clicking the "Check all" button in area AD02 will check all selected children at once. At this point, the checker can be added or changed using the button in area AD03. Tapping or clicking the "Back" button in area AD04 will cause the window in area AD01 to disappear and the nap check for that session to end.

When you tap or click on the "Memo" button in area AD05 in Figure 6, a window will appear where you can enter memos (information) about the child's condition, etc. (see area AE01 in Figure 7).

By tapping or clicking the "Cough," "Phlegm," "Sideways," "Vomiting," "Snoring," "Return to facedown," and "Fever" buttons in area AE02 in Figure 7, notes can be quickly entered about the child's condition. In addition, the caregiver (checker) can freely write the child's condition at the time of the check in area AE03.

The server storage unit 24 or the terminal storage unit 38 stores information about the heart rate during the nap check and information about the condition such as "coughing" for each child and for each specified period TT1. The information about the heart rate during the nap check and information about the condition such as "coughing" stored here is used when displaying information about nap checks (check results, etc.) from past dates and times.

As shown in FIG. 8, if an abnormality occurs in a child's physical condition during nap monitoring and the detection unit 12 detects an abnormality in the vital signs (physical condition), an alert window will pop up in area AF01 indicating that "an abnormality has occurred in a child's physical condition." In the example of FIG. 8, for example, the heart rate detection unit 121 detects that "B-chan's" heart rate has remained at "120 bpm or higher" for two minutes, and it is displayed that "B-chan's" heart rate is "120 bpm or higher." Here, the caregiver (verifier) can check the child's condition and take appropriate measures, or after confirming that there is no abnormality, the alert can be cancelled by tapping or clicking the "Cancel Alert" button in area AF02. Note that the criteria for normal and abnormal heart rates and alerts are not limited to the above criteria and can be changed to any criteria.

As shown in Figure 9, by tapping or clicking area AG01 and selecting "Nap Check Sheet," the nap check information for that day can be displayed in sheet format. Caregivers can also modify (edit) the nap check information by tapping or clicking the "Edit" button in area AG02. Caregivers can also print the nap check sheet (nap check information) by tapping or clicking the "Print" button in area AG03.

In the "Location Management" screen that is displayed by tapping or clicking on area AH00 shown in FIG. 10, the caregiver can check the location information (whereabouts, behavior) of the child wearing the sensor device 10. In area AH01, an image G01 corresponding to the child is displayed based on the detected location information of the child, superimposed on the map image at a position corresponding to the location information. This allows the caregiver to visually confirm the whereabouts of the child.

<6> The display information displayed in area AH01 is an image generated by the display information generating unit 22 or the display information generating unit 32 based on the position information detected by the position information detecting unit 124 of the detecting unit 12, so as to superimpose an image G01 corresponding to a child on the map image at a position corresponding to the position information.

The caregiver can set an "inside kindergarten area" corresponding to the geographical range of the kindergarten in any area on the map image (area AH02). Area AH03 displays the names of children who are in the "inside kindergarten area", children who are not in the "inside kindergarten area" ("outside kindergarten"), and children who cannot connect to the sensor device 10. In the example of Figure 10, child "Q-chan" is displayed outside the "inside kindergarten area" in area AH01, and "Q-chan" is displayed in the "outside kindergarten" column in area AH03. This allows the caregiver to easily know that "Q-chan" is "outside kindergarten".

<3> The alert unit 34 or the alert unit 13 outputs an alert when it is determined that the child has left the "school area" (area AH02), which is a predetermined geographical range, based on the detected child's location information. For example, the alert unit 34 of the terminal device 30 can output an alert indicating that "the child has left the school area" by text or image from the display (display unit 33), or by voice from the speaker. Also, for example, the alert unit 13 of the sensor device 10 can output an alert indicating that "the child (yourself) has left the school area" by a beep from a buzzer or vibration from a vibrator. This allows the caregiver and the child to notice that "the child (yourself) has left the school area." The alert output by the alert unit 34 or the alert unit 13 can be set on or off by the caregiver for each sensor device 10 and each terminal device 30 (same below).

As shown in FIG. 11, when the image of any child on the map image (for example, "C-chan") is tapped or clicked, the child's name and a "Play Sound" button, a "Route from current location" button, and a "Daily track" button are displayed in area AI01. When the "Play Sound" button (area AI02) is tapped or clicked, a beep or voice is output from the buzzer or speaker of the sensor device 10 attached to "C-chan." This can be used to warn "C-chan" if she is in a dangerous place, for example.

As shown in FIG. 12, when the "Daily Track" button (area AJ01) is tapped or clicked, a one-day track (location history) of the child's whereabouts is displayed in area AJ02. A one-day track is displayed, for example, by displaying an image of the child (child image) along with the time at a position on the map image that corresponds to the child's location information for each hour, and connecting the child images with lines from oldest to newest (see FIG. 12). This allows caregivers to reflect on the child's behavior throughout the day. By repeatedly reflecting on the child's behavior, it is possible to learn about the child's behavioral trends, such as whether the child often enters dangerous places.

In addition to the time, images of each child in the daily trajectory may also display, for example, heart rate or heart rate information (normal or abnormal). This allows the relationship between the child's behavior and heart rate to be known.

When the "Route from current location" button in area AJ03 in FIG. 12 is tapped or clicked, the route from the terminal device 30 to the child is displayed on a map image. <7> The display information displayed here is an image generated by the display information generating unit 22 or the display information generating unit 32 based on the position information detected by the position information detecting unit 124 of the detection unit 12 and the terminal position information detected by the terminal position information detecting unit 36, so as to superimpose the route from the terminal device 30 to the child on the map image.

As shown in FIG. 13, by tapping or clicking area AK01 to switch to "walk mode," the mode can be set to a mode suitable for walks, which are outdoor activities. In "walk mode," the destination of the walk can be set by tapping or clicking the "set destination" button in area AK02. In destination setting, an "activity area," which is a geographical range that corresponds to the destination, can be set at any position on the map image. When starting a walk with the children, the caregiver taps the "start walk" button in area AK03.

When the "Start Walk" button is tapped, an image (caregiver image) corresponding to the caregiver (teacher) and a circle of a specified size with the caregiver image at its center are displayed on the map image (see area AL01 in FIG. 14). Area AL02 displays the names of children who are in the "safety area" which is a specified distance (area) from the caregiver, children who are not in the "safety area" (outside the safety area), and children who cannot connect to the sensor device 10. In the example of FIG. 14, in area AL01, child "Q-chan" is displayed outside circle C1 ("inside the safety area") centered on caregiver X1 and circle C2 ("inside the safety area") centered on caregiver X2, and "Q-chan" is displayed in the "outside the safety area" column of area AL02. This allows the accompanying caregivers (caregivers X1 and X2) to easily understand that "Q-chan" is outside the "safety area".

<4> The alert unit 34 or the alert unit 13 outputs an alert when the distance detection unit 35 detects that the distance between the terminal device 30 carried by the caregiver and the sensor device 10 attached to the child is equal to or greater than a predetermined distance. For example, the alert unit 34 of the terminal device 30 can output an alert indicating that the child has left the "safety area" by text or images from the display (display unit 33) or by voice from the speaker. Also, for example, the alert unit 13 of the sensor device 10 can output an alert indicating that the child (the child) has left the "safety area" by a beep from a buzzer or vibration from a vibrator. This allows the caregiver and the child to realize that the child (the child) has left the "safety area". The criteria for being inside or outside the safety area and for the alert are not limited to the above criteria and can be changed to any criteria.

When the caregiver arrives at the destination (the "activity area"), area AM01 displays the names of children who are in the "activity area", children who are not in the "activity area" (outside the activity area), and children who cannot connect to the sensor device 10 (see Figure 15). In the example of Figure 15, child "Q-chan" is displayed outside the "activity area" in area AM02, and "Q-chan" is displayed in the "outside activity area" column in area AM01. This allows the caregiver to easily know that "Q-chan" is outside the "activity area".

<3> The alert unit 34 or the alert unit 13 outputs an alert when it is determined that a child has left the "activity area", which is a specified geographical range, based on the detected child's location information. For example, the alert unit 34 of the terminal device 30 can output an alert indicating that "a child has left the activity area" by text or image from the display (display unit 33), or by sound from the speaker. Also, for example, the alert unit 13 of the sensor device 10 can output an alert indicating that "the child (the child) has left the activity area" by a beep from a buzzer or vibration from a vibrator. This allows the caregiver and child to realize that "the child (the child) has left the activity area." Note that the criteria for being inside or outside the activity area and for alerts are not limited to the above criteria and can be changed to any criteria.

In the "Health Alert" screen, which is displayed by tapping or clicking on area AN00 shown in FIG. 16, the caregiver can check any abnormalities (alert details) that have occurred in the health (biometric information) of the child wearing the sensor device 10. For example, area AN01 on the screen displays the name of the child whose biometric information (health) has been detected to be abnormal, the alert details (details of the abnormality), and other information. In addition, in the row of the child's name, "inside the nursery" or "outside the nursery" is displayed as the location where the abnormality occurred ("location of occurrence"). This allows the caregiver to easily check whether the abnormality occurred inside or outside the nursery. Note that "inside the nursery" or "outside the nursery" is displayed as the location where the abnormality occurred ("location of occurrence") based on the location information detected by the location information detection unit 124 when the abnormality occurred.

In area AN01, the time the abnormality occurred ("hour"), "processing status", and "processor" are displayed in the row of the child's name. For example, a caregiver can check the physical condition of a child whose "processing status" is "unprocessed" by visually inspecting, measuring, listening, etc., and after taking appropriate measures or confirming that there are no abnormalities, can tap or click area AN02 to change the "processing status" to "processing completed".

Next, we will explain further functions of the physical condition and behavior monitoring system 1.

<9> When the predetermined period change unit 23 or the predetermined period change unit 37 determines that "the child is asleep" based on the sleeping condition, which is a predetermined condition, it "changes the first predetermined period T1 to be shorter than before the determination" and/or "changes the second predetermined period T2 to be longer than before the determination."

Specifically, the above-mentioned "sleeping conditions" are, for example, "when the caregiver taps or clicks the "Start Nap Monitoring" button (area AB01) on the "Nap Check" screen shown in Figure 4" or "when the caregiver taps or clicks the "Start Nap" button on the screen shown in Figure 5." When the specified

period changing unit

23 or 37 determines for each child, i.e., for each sensor device 10, that "the child is asleep (has started to sleep)" based on the sleeping conditions (sleep start conditions), it "changes the first specified period T1 to, for example, 30 seconds so that it is shorter than the 1 minute before the judgment" and "changes the second specified period T2 to, for example, 10 hours so that it is longer than the 1 minute before the judgment." As a result, during the nap, "the first predetermined period T1, which is the interval for detecting biological information, is changed to be shorter than before the judgment" to detect information regarding the child's physical condition while he or she is napping (asleep) with high accuracy, while "the second predetermined period T2, which is the interval for detecting location information, is changed to be longer than before the judgment" to reduce power consumption of the sensor device 10 and improve battery life 14.

The above "asleep condition (sleep start condition)" may be, for example, "when the caregiver taps or clicks the "Start Nap Monitoring" button (area AB01) on the "Nap Check" screen shown in FIG. 4" or "when the caregiver taps or clicks the "Nap Start" button on the screen shown in FIG. 5" and "when the child is in the "nursery area." The above "asleep condition (sleep start condition)" may be, for example, "when it is estimated that 'the child is asleep (has started sleeping)' based on the child's biological information and/or movement information detected by detection unit 12."

The "asleep condition" is released, for example, when "the caregiver taps or clicks the 'wake up' button or the 'wake up everyone' button (area AC03) on the screen shown in FIG. 5." This causes the first specified period T1 and the second specified period T2 to return to the values before the change (before the determination). The "asleep condition" may also be released, for example, when "it is estimated that 'the child has woken up (sleep has ended)' based on the child's biometric information and/or movement information detected by the detection unit 12."

<10> When the specified period change unit 23 or the specified period change unit 37 determines that "the child is engaged in activities outside a specified geographical area" based on the specified condition of "out-of-area activity," it "changes the first specified period T1 for the body temperature and blood oxygen concentration, which are among the vital signs, to be longer than before the determination."

Specifically, the above-mentioned "out-of-area activity condition" is, for example, "when the caregiver taps the "Start walk" button (area AK03) on the "Walk mode" screen shown in FIG. 13." When the predetermined period change unit 23 or the predetermined period change unit 37 determines based on the out-of-area activity condition that "the child is active outside a predetermined geographical area ("walk mode", on a walk)," it "changes the first predetermined period T1 for the body temperature and blood oxygen concentration among the biological information to, for example, 10 hours, so that it is longer than the 1 minute before the determination." In this way, by "changing the first predetermined period T1 for the body temperature and blood oxygen concentration among the biological information to be longer than the 1 minute before the determination," it is possible to reduce the power consumption of the sensor device 10 and improve the battery life of the battery 14, while continuing to detect only information related to the heart rate during the child's out-of-area activity.

The above-mentioned "out-of-range activity condition" is released, for example, when "on the "Walk mode" screen shown in FIG. 13, the caregiver taps the "Start walk" button (area AK03), arrives at the destination, and returns to the kindergarten."

<5> When the heart rate of the biological information detected by the detection unit 12 suddenly becomes zero, the alert unit 34 determines that the heart rate has not actually become zero, but that the sensor device 10 has been removed from the child's body, and outputs an alert. For example, the alert unit 34 of the terminal device 30 outputs an alert indicating that the sensor device 10 has been removed from the child's body by using text or images from the display (display unit 33) or audio from the speaker. This allows the caregiver to become aware that the sensor device 10 has been removed from the child's body.

<2> When any of the vital signs detected by the detection unit 12, such as heart rate, body temperature, or blood oxygen concentration, falls outside a predetermined range, the alert unit 34 determines that "something is wrong with the child's health" and outputs an alert. For example, the alert unit 34 of the terminal device 30 outputs an alert indicating that "something is wrong with the child's health" by text or images from the display (display unit 33), or by audio from the speaker. This allows the caregiver to become aware that "something is wrong with the child's health." The pop-up display of a window (see area AF01 in Figure 8) indicating that there is something wrong with the child's heart rate is an example of the operation of the alert unit 34.

In this embodiment, the conditions (criteria) for alert output, on/off of alert output, alert volume, detection timing (detection interval) of biometric information or positional information by the detection unit 12, etc. can be changed for each of multiple children and for each sensor device 10 attached to the child.

As described above, <1> in this embodiment, the sensor device 10 can be attached to the body of a child as a person to be monitored. The detection unit 12 can detect the child's heart rate as biometric information, and can detect the child's location as location information. The

processing units

100, 200, 300 can process the biometric information and/or location information detected by the detection unit 12. The display

information generation units

22, 32 can generate display information based on the biometric information and/or location information detected by the detection unit 12 or processed by the

processing units

100, 200, 300.

The display unit 33 can display the display information generated by the display

information generating units

22 and 32. Therefore, the caregiver who is the supervisor can monitor the behavior of the children as well as their physical condition by checking the display information displayed on the display unit 33.

By monitoring the biological information (physical condition) and location information (whereabouts) of children using the health and behavior monitoring system 1, it is possible to quickly detect signs of sudden infant death syndrome (SIDS), for example, during naptime in the kindergarten, and to prevent accidents and injuries both inside and outside the kindergarten.

<2> In this embodiment, the device further includes an

alert unit

13, 34 that can output an alert when the biometric information and/or location information detected by the detection unit 12 meets a predetermined condition. This allows the caregiver (supervisor) to quickly become aware of any abnormalities in the physical condition or location of the child (person being monitored).

<3> In this embodiment, the

alert units

13 and 34 output an alert if they determine, based on the location information, that a child has left a specified geographical area. This allows the caregiver (supervisor) or child (person being monitored) to quickly notice, for example, that a child has gone outside the kindergarten grounds.

<4> This embodiment further includes a distance detection unit 35 capable of detecting the distance between the terminal device 30 and the sensor device 10. The

alert units

13, 34 output an alert when the distance detection unit 35 detects that the distance between the terminal device 30 and the sensor device 10 is greater than a predetermined distance. This allows the caregiver (supervisor) or child (person being monitored) to quickly notice, for example, that the child (sensor device 10) has moved away from the caregiver (terminal device 30) by a predetermined distance or more while on a walk.

<5> In this embodiment, when the heart rate of the biological information detected by the detection unit 12 becomes 0, the alert unit 13 determines that "the sensor device 10 has been removed from the child (person being monitored)" and outputs an alert. This allows the caregiver (monitor) to quickly notice that the sensor device 10 has been removed from the child's body.

<6> In this embodiment, the display

information generating units

22 and 32 can generate display information in which an image corresponding to a child (a person to be monitored) is superimposed on a position on the map image corresponding to the position information detected by the detecting unit 12. This allows caregivers to easily visually confirm the whereabouts of the child.

<7> This embodiment further includes a terminal location information detection unit 36 that can detect terminal location information, which is the location of the terminal device 30. The display

information generation units

22 and 32 can generate display information in which the route from the terminal device 30 to the child (person to be monitored) is superimposed on a map image, based on the location information detected by the detection unit 12 and the terminal location information detected by the terminal location information detection unit 36. This allows the caregiver to easily visually confirm the route to the child.

<8> In this embodiment, the detection unit 12 detects biometric information every first predetermined period T1, and detects location information every second predetermined period T2. This embodiment further includes a predetermined

period change unit

23, 37 that can change at least one of the first predetermined period T1 or the second predetermined period T2. As a result, for example, under certain conditions, the first predetermined period T1 can be changed to be shorter to increase the detection accuracy (detection frequency) of information related to physical condition, or the second predetermined period T2 can be changed to be longer to improve the life of the battery 14 of the sensor device 10.

<9> In this embodiment, when the predetermined

period change unit

23, 37 determines that "the child (person being monitored) is asleep" based on the sleeping condition, which is a predetermined condition, it "changes the first predetermined period T1 to be shorter than before the determination" and/or "changes the second predetermined period T2 to be longer than before the determination." As a result, for example, while the child is taking a nap, the first predetermined period T1 can be shortened to increase the detection accuracy (detection frequency) of information related to the physical condition, while the second predetermined period T2 can be lengthened to improve the life of the battery 14 of the sensor device 10.

<10> In this embodiment, the detection unit 12 can detect the child's (person being monitored) heart rate as well as body temperature and blood oxygen concentration as biometric information. This allows for more detailed monitoring of the child's physical condition. When the predetermined

period change unit

23, 37 determines that the child (person being monitored) is active outside a predetermined geographical range based on the predetermined condition of out-of-range activity, it changes the first predetermined period T1 for the body temperature and blood oxygen concentration, which are among the biological information, to be longer than before the determination. This allows the battery 14 of the sensor device 10 to last longer during out-of-range activities, such as during walks, while continuing to detect only information related to the heart rate and monitoring the physical condition.

Other Embodiments
In other embodiments, <9-1> when the specified period changing unit 23 or the specified period changing unit 37 determines that "the child is sleeping" based on a specified condition, which is a sleeping condition, it may "change the third specified period T3 to be longer than before the determination."

Specifically, when the predetermined period changing unit 23 or the predetermined period changing unit 37 determines for each child, i.e., for each sensor device 10, that "the child is asleep (has started sleeping)" based on the sleeping condition (sleep start condition), it "changes the third predetermined period T3 to, for example, 10 hours so that it is longer than the 0.625 ms to 1.28 s before the judgment." This reduces the power consumption of the sensor device 10 and improves the life of the battery 14 by "changing the third predetermined period T3, which is the interval for detecting motion information, to be longer than before the judgment" during a nap. Note that when the "sleeping condition" is released, the third predetermined period T3 returns to the value before the change (before the judgment).

In another embodiment, the <10-1> predetermined period change unit 23 or the predetermined period change unit 37 may "change the third predetermined period T3 to be longer than before the judgment" when it is determined that "the child is not engaged in activities outside the predetermined geographical range ('walking mode', not on a walk)" based on the predetermined condition of the out-of-range activity condition. This reduces the power consumption of the sensor device 10 and improves the life of the battery 14 by "changing the third predetermined period T3, which is the interval for detecting the motion information, to be longer than before the judgment" when not in "walking mode", i.e., not on a walk. Note that when it is determined that "the child is engaged in activities outside the predetermined geographical range ('walking mode', on a walk)" based on the above "out-of-range activity condition", the third predetermined period T3 returns to the value before the change (before the judgment).

In the above embodiment, as the criteria for normal/abnormal heart rate and alert, when the heart rate is below a predetermined value (e.g., 60 bpm), "60 bpm or less" (abnormal: bradycardia) is displayed or an alert is given, when the heart rate is above a predetermined value (e.g., 120 bpm), "120 bpm or more" (abnormal: tachycardia) is displayed or an alert is given, and when the heart rate is higher than 60 bpm and lower than 120 bpm, "normal heart rate" (normal) is displayed. In contrast, in other embodiments, for example, during a nap, an alert may be output by screen display and audio, etc., indicating that the child is in danger when "the heart rate is 40 bpm or less and this (abnormal: bradycardia) state continues for two minutes" or when "the heart rate is 170 bpm or more and this (abnormal: tachycardia) state continues for two minutes." Note that it is preferable to set/change the specific numerical values (heart rate, abnormal duration) used as the criteria for determining whether the heart rate is normal/abnormal depending on the age of the child being monitored.

In another embodiment, when heading to a destination in "walk mode" and there is a single caregiver (teacher) in charge, for example, an area within a 10m radius of the terminal device 30 carried by the caregiver is defined as a "safe area," and if 30 seconds have passed since the child (sensor device 10) left the "safe area," an alert may be output by screen display, audio, etc., indicating that the child is in danger.

In another embodiment, when heading to a destination in "walk mode" and there are two or more accompanying caregivers (teachers), the "safety area" may be, for example, the space between the caregivers and within a 5 m radius of the terminal device 30 carried by each caregiver, and if 30 seconds have passed since the child (sensor device 10) left the "safety area," an alert may be output by screen display, audio, etc., indicating that the child is in danger.

In another embodiment, when a destination is reached in "walk mode", a "safety area" ("activity area") is set according to the topography of each destination, regardless of the position or number of accompanying caregivers (teachers), and if, for example, one minute has passed since a child (sensor device 10) left the "safety area (activity area)", an alert may be output by screen display, audio, etc., indicating that the child is in danger. Note that it is desirable to set/change specific numerical values (size of the range of the safety area, distance between the child (sensor device 10) and the caregiver's terminal device 30, duration of the abnormal state, etc.) as criteria for determining the safety of the child's location (placement) depending on the age, etc. of the child being monitored.

In another embodiment, in "walk mode", for example, the motion detection unit 125 may detect a child's fall, and the heart rate detection unit 121 may detect an abnormal heart rate. If this (abnormal) state continues for 30 seconds, an alert may be output by screen display, audio, etc., indicating that the child is in danger.
