Further, the information processing apparatus 200 may appropriately use SaaS, PaaS, and IaaS by a cloud server without providing dedicated software, hardware, OS, etc. for the sleep check system 100 .

The terminal device 300 may be an electronic device such as a mobile terminal owned by a user such as a nursery teacher who uses the sleep check system. Examples include mobile terminals, tablet terminals, smartphones, wearable terminals, personal computers, and other terminal devices. may be

Network 500 is, for example, an IP network. As long as the network 500 is an IP network, it may be wireless, wired, or a combination of wireless and wired. A LAN access point (not shown) may be accessed to communicate with the information processing apparatus 200 via a LAN or WAN. Also, the network 500 is not limited to these examples, and may be, for example, a public switched telephone network, Bluetooth (registered trademark), an optical line, an ADSL line, a satellite communication network, or the like.

Here, an overview of the sleep check system 100 according to one embodiment of the present invention will be described using FIG. FIG. 3 is a schematic diagram showing an overview of the sleep check system 100 according to one embodiment of the present invention.

As shown in FIG. 3 , in the sleep check system 100, as an example, a sensor device 400 attached to a sleep check target person such as an infant (hereinafter simply referred to as “subject”) detects the body movements of a plurality of infants during sleep. 1. Detects orientation, body temperature, presence or absence of breathing, etc. The detected data (sensing data) is transmitted to the terminal device 300 . The terminal device 300 receives the sensing data; 2. collecting sleep state information (posture information, etc.) indicating the sleep state of each infant to be checked; 3. Based on the collected sleep state information, the average number of times of rolling over in a predetermined time period is calculated for each target infant or for each of a plurality of grouped infant groups; 5. Based on the calculated average number of times of rolling over, it is determined whether or not the baby rolls over frequently for each infant or for each group; Including the determination result, display information is generated for displaying the sleep state such as body orientation, body temperature, and whether the baby rolls over frequently for each infant or group to be checked.

6. As shown in FIG. 7. When the generated display information is transmitted to the display unit 341 of the terminal device 300; For each infant, (1) whether or not they are asleep, (2) display of body orientation (for example, text display such as "upside down", image display of up arrow), (3) display of body temperature at predetermined time intervals The list is displayed on the screen all at once (for example, every 5 minutes).

Here, the "sleep state" refers to the orientation of the body, body temperature, presence or absence of breathing, etc. at a certain point in time when an infant is asleep. In addition, "sleep state information" here means posture information indicating the orientation of the infant's body, body temperature information indicating the infant's body temperature, breathing information indicating the presence or absence of breathing of the infant and breathing rate. It is configured to include information indicating the state of affairs.

The sleep check system 100 can collectively accept check inputs for the target infant at predetermined time intervals on the screen display. For example, as shown in FIG. 3, a check button for inputting that all the target infants have been checked is provided for the display representing the body orientation of each infant at 12:10 displayed on the display unit 341. Then, when the check button is pressed and executed, the display representing the body orientation of all the target infants in the column at 12:10 is changed to the columns at 12:00 and 12:05. (1) Check button The text display changes from "checked" to "done", (2) the frame line of the arrow and the emoticon indicating waking up changes from a solid line to a dotted line, and (3) the name of the nursery teacher who checked it is "Mr. Yuka". is displayed as text at the bottom of the column of the target infant, (4) the column of the checked target time is uniformly grayed out, etc., so that the completion of the check can be understood at a glance.

Conventionally, when a user such as a nursery teacher checks the sleeping state of each child at predetermined intervals and records the check results by hand, if the predetermined time is 5 minutes, the user will be in charge of a certain time. It takes 5 minutes just to check the sleep status of all the children in the class and record the check results by hand, and the next check starts before or immediately after completion. There was a problem that the burden of sleep check work was heavy. In response to such a problem, with such a configuration of the sleep check system 100, it is possible to collectively input the results checked by the user based on the sleep state detected by the sensor device 400 without recording by handwriting. Since the display of the part where the input is received is changed, it can be seen at a glance whether or not the check has been completed, so the burden of the nursery teacher's sleep check such as afternoon nap check can be reduced.
(Functional configuration)
FIG. 2 is a diagram showing a functional configuration example of the sleep check system 100 according to one embodiment of the present invention. As shown in FIG. 2 , sleep check system 100 includes information processing device 200 , terminal device 300 , and sensor device 400 .

Specifically, the sleep check system 100 is a sleep check system that checks the sleep state of a plurality of subjects, is attached to the subject, and detects the orientation of the subject's body at each first predetermined period. a detection unit 440; a collection unit 311 that collects posture data indicating the body orientation of each subject detected by the detection unit 440 and generates posture information; A display unit 341 that collectively displays, and an operation input unit 351 that collectively accepts an input for confirming a part or all of the subjects with respect to the displayed body orientation of each subject, and the display unit 341 is to change the display of the direction of the body of the subject whose confirmation has been input, when the confirmation input of the operation input unit 351 is received.

Here, the "first predetermined period" means an interval time for the posture detection unit 441 to detect the orientation of the subject's body. , the first predetermined period is "5 minutes". In the setting of the first predetermined period, in checking the sleeping state, it is sufficient to set how many minutes it is desired to check the orientation of the subject's body (sleeping on his back or sleeping on his stomach) according to measures against suffocation and SIDS. .

With such a configuration, the sleep check system 100 receives an input indicating that the sleep state of the infant has been checked collectively, and changes the display of the sleep state for which the input has been received. It is possible to provide a sleep check system that allows a kindergarten child to complete sleep check input in one go and confirm at a glance whether or not the check has been completed.

The “posture data” referred to here is data indicating the orientation of the body of the target infant detected by the detection unit 440. For example, the orientation detection unit 441 detects the orientation of the body using an acceleration sensor or a gyro sensor. In some cases, it is referred to as data indicating the degree of inclination (angle) from the initial value at the start of detection. Also, the "posture information" here is information indicating the orientation of the body of the target infant (supine, prone, etc.) determined from the orientation data.
(Information processing device 200)
The information processing apparatus 200 includes a control section 210, a communication section 220, and a storage section 230, as shown in FIG.

The control unit 210 is a processor that includes a collection unit 211 , a calculation unit 212 , and a determination unit 213 and has a function of controlling each functional unit of the information processing apparatus 200 . Also, the control unit 210 may include a generation unit 214 .

For example, the control unit 210 refers to various information such as sleep state information stored in the storage unit 230 based on processing requests from the functional units of the terminal device 300, the sensor device 400, or the information processing device 200. An update or deletion process may be performed, and output information for outputting the result of the process on the terminal device 300 may be generated. In this case, the generated output information is transmitted to the terminal device 300 via the communication unit 220 and network 500 .

Here, “output information” refers to display information and audio information output by the output unit 340 of the terminal device 300 . In addition to these information, any information may be used as long as the sleeping state of infants such as kindergarten children can be output to a user such as a nursery teacher. , may be output by vibration of the terminal device 300 .

The collection unit 211 has a function of collecting data detected and output by the sensor device 400 . For example, the collection unit 211 collects posture data indicating the orientation of the body of each subject detected by the detection unit 440 of the sensor device 400, and generates posture information. In the collection method of the collection unit 211, sensing data such as posture data received from the sensor device 400 is temporarily stored in the storage unit 230 for a predetermined period, and collected in response to an output request from the terminal device 300. Alternatively, the sensing data may be collected in pseudo-real time at the timing received from the sensor device 400 . The collection unit 211 may store the collected various data and the generated various information (posture information, body temperature information, etc.) in the storage unit 230 . The collection unit 211 may calculate the number of rollovers during the third predetermined period based on the stored posture information, and store the posture information including the calculation result. When calculating the number of rollovers in the collection unit 211, for example, the number of rollovers may be calculated by counting up (incrementing) each time the body orientation changes to the supine, sideways, or prone state. Alternatively, a predetermined angle reference or angle range may be provided, and when the reference or range is exceeded, the number of times may be calculated by counting up.

As an example, the collection unit 211 may also collect temperature data indicating the body temperature of each subject detected by the detection unit 440 of the sensor device 400 and generate body temperature information.

The “temperature data” here is data indicating the body temperature of the target infant detected by the detection unit 440. For example, when the temperature detection unit 442 detects the temperature using a thermometer or a thermographer, It refers to the temperature measured from the far infrared rays radiated from the part of the target infant's body that is in contact with the temperature detection unit 442 or from the inside of the body. Here, the "body temperature information" is information indicating the body temperature and normal temperature obtained from the temperature data of the target infant at a certain point in time.

The calculation unit 212 has a function of calculating an average value or the like for a certain period based on data stored in the storage unit 230 . Specifically, the calculation unit 212 calculates the average number of times of rolling over in the third predetermined period for each subject based on the posture data stored in the storage unit 230, for example. The calculation unit 212 may store the calculated average number of times in the storage unit 230 .

Here, the "third predetermined period" is a period during which the number of times the subject turns over during sleep is checked, and whether the subject is in a sleeping state or an awake state. When the nursery teacher checks the afternoon nap, the nap time (for example, 1 hour, 2 hours) may be set as the third predetermined period. In addition, periods separated by average REM sleep and non-REM sleep time of infants (for example, one set of REM sleep and non-REM sleep for each age, late fetal period to neonatal period: 40 to 50 minutes, 3 to 4 years old : 40 to 60 minutes, adults: 90 to 100 minutes) may be set as the third predetermined period.

Further, the calculation unit 212 may calculate the average body temperature for the fifth predetermined period based on the temperature data stored in the storage unit 230 for each subject.

Here, the "fifth predetermined period" is the period during which the body temperature of each subject is checked. or nap time (for example, 1 hour, 2 hours) may be set as the fifth predetermined period. Also, a period divided by average REM sleep and non-REM sleep time of an infant may be set as the fifth predetermined period.

The determining unit 213 has a function of determining based on information stored in the storage unit 230 . Specifically, for example, the determination unit 213 compares the number of times of tossing and turning indicated by the posture information stored in the storage unit 230 with the average number of times of turning over calculated by the calculation unit 212 for each subject. It is determined whether or not there are many rollovers during the predetermined period of 3.

Here, the "second predetermined period" refers to the period during which various data of the subject are accumulated in the storage unit 230. For example, in the case of sleep checks for infants enrolled in a nursery school, each child from the beginning of enrollment to the current time. Alternatively, as another example, the period may be six months, one year, five years, or ten years, depending on the operating environment of the sleep check system such as the storage capacity of the storage unit 230 .

The determination unit 213 may determine whether the subject is in a sleeping state or an awake state from a change in body orientation (body movement) during the third predetermined period. Here, an example of a method for determining whether the subject is in a sleeping state or an awake state from changes in body orientation in the determination unit 213 during the third predetermined period will be described with reference to FIG. 7 . FIG. 7 is a graph with the vertical axis representing the amount of change in body orientation (angle [°] from the reference position) and the horizontal axis representing time (seconds). The graph is a graph plotting over time the change amount data of the angle from the reference position for each of the sensor devices 400 (S1, S2, . . . S10) attached to the subject.

Specifically, the determining unit 213 determines the change over time of the inclination of the body detected by the detecting unit 440 of the sensor device 400 as a third predetermined value for each sensor device 400, which is plotted in the graph shown in FIG. The determination may be made using the following methods (1) to (3) based on the angle data group from the set reference position included in the posture data stored for the period.

(1) As an example, the determination unit 213 extracts, from the posture data stored in the storage unit 230, the feature amount of the orientation of the body of the posture data in each of the sleep state and the wakeful state, and prepares a state determination model in advance. Then, using the constructed state determination model, it may be determined whether the subject is in the sleeping state or in the wakeful state based on the feature amount of the body orientation during the third predetermined period. Specifically, for example, the determining unit 213 extracts feature amounts from angle data groups included in the posture data as explanatory variables and sleep and wakefulness states as objective variables, and combines the feature amounts to obtain training data. do. The determination unit 213 builds a state determination model by learning by machine learning (for example, a learning technique such as SVM (Support Vector Machine)) using the learning data. The determination unit 213 stores the constructed state determination model in the storage unit 230 . The determination unit 213 performs pattern recognition using the stored state determination model based on the feature amount of the body orientation of the posture data collected in the third predetermined period, and determines whether the state is in the sleep state or the wakeful state. It may be judged (classified) whether or not there is any. With such a configuration, if the orientation of the subject's body is detected, it is possible to accurately predict whether the subject is in a sleeping state or an awake state. You can save the trouble of checking whether you are awake or not, and you can reduce the burden of sleep checks.

(2) As another example, the determination unit 213 counts the number of passages of the graph to the reference angle or angle region in the target period in the graph shown in FIG. If the number of times is greater than or equal to , it may be determined that the user is in an awake state. Alternatively, if the counted number of passages is smaller than a predetermined number of times, it may be determined that the user is in a sleeping state.

(3) In addition to the above (1) and (2), the determination unit 213 uses interpolation, regression analysis, etc. for the graph shown in FIG. A determination method may be used in which a curve that minimizes the distance of is determined, and whether the sleep state or the wakeful state is determined (classified) based on the determined curve.

The determination unit 213 compares the average body temperature calculated by the calculation unit 212 with the body temperature indicated by the generated body temperature information for each subject, and determines whether the body temperature is normal during the third predetermined period. You may

The determination unit 213 determines whether the subject is in the sleeping state or the awake state from the change in the body orientation during the sixth predetermined period, and determines that the subject has transitioned from the awake state to the sleeping state. Assuming that the user has begun to sleep, a start processing request may be issued to start posture detection and temperature detection by the detection unit 440 of the sensor device 400 under preset conditions.

For example, in a state before the subject begins to sleep (awakening state), the determination unit 213 determines that posture detection and temperature detection by the detection unit 440 of the sensor device 400 are partially stopped (an interval obtained by thinning out the first predetermined period). posture detection state, detection stop of temperature detection, sleep state, etc.), the determination unit 213 determines that the subject has begun to sleep and transitions to the sleep state. A start processing request is transmitted to the detection unit 440 of the sensor device 400 to start a full-scale sleep check, such as detecting the orientation of detection may be initiated to initiate a routine sleep check. With such a configuration, unnecessary detection of the arousal state can be omitted, and the orientation of the subject's body can be detected efficiently from the viewpoint of processing performance, communication capacity, and storage capacity. can.

The determination unit 213 groups the subjects, and among the grouped subjects, at least one of the number of people determined to turn over frequently or the number of people determined to have abnormal body temperature is greater than a predetermined number of people. It may be determined whether Specifically, for example, in the case of an afternoon nap check at a nursery school, the determination unit 213 groups the children by the class in which they are enrolled, and among the grouped children, the number of children who turn over frequently or the number of children whose body temperature is higher than usual. It may be determined whether or not any one of the numbers is greater than a predetermined number. Here, the "predetermined number of people" may be half or two-thirds of the number of people to be grouped, and may be set according to the sleep check system.

In addition to the above, the determination unit 213 may determine whether or not the subject is in a state different from usual sleep. For example, (1) the body temperature increase rate is compared with a predetermined increase rate. (2) It may be determined whether the number of times of waking up and falling asleep is more than a predetermined number (it is difficult to fall asleep). (3) Machine learning may be used to extract features of the body orientation of the sleeping state where the person sleeps on the stomach, and predict and determine the sleeping state of the person lying on the stomach.

The generation unit 214 generates output information (display information, audio information) to be output by the terminal device 300 based on various information stored in the storage unit 230 . Specifically, the generation unit 214 generates display information to be displayed on the display unit 341 as shown in FIGS. You may The generation unit 214 transmits the generated output information to the output unit 340 of the terminal device 300 via the communication unit 220 and the network 500 .

The communication unit 220 has a function of executing communication with the terminal device 300 , the sensor device 400 or another information processing device 200 via the network 500 under the control of the control unit 210 . The communication may be wired or wireless, and any communication protocol may be used as long as mutual communication can be performed. Specifically, the communication unit 220 may transmit output information to the terminal device 300 and receive sensing data from the sensor device 400 .

The storage unit 230 has a function of storing various programs, data, parameters, and the like required when the information processing apparatus 200 performs calculation and processing under the control of the control unit 210 .

The storage unit 330 has a function of storing various programs, data, parameters, etc. required when the terminal device 300 operates under the control of the control unit 310 . Specifically, the storage unit 330 stores, for example, sensing data (posture data, temperature data), posture information, body temperature information, personal information, and the like. Specifically, the storage unit 330 is configured by, for example, a main storage device configured with a ROM and a RAM, an auxiliary storage device configured with a nonvolatile memory, etc., and various recording media such as an HDD, an SSD, and a flash memory. .

The output unit 340 includes a display unit 341 and an audio output unit 342 and has a function of outputting various information to the terminal device 300 under the control of the control unit 310 . The output unit 340 collectively outputs the body orientation of each subject based on the posture information stored in the storage unit 330, for example.

The display unit 341 has a function of outputting various information such as posture information under the control of the control unit 310 .

The display unit 341 collectively displays the body orientation of each subject based on the posture information stored in the storage unit 330 under the control of the control unit 310 . Further, when the display unit 341 receives a confirmation input from the operation input unit 351 under the control of the control unit 310, the display unit 341 collectively changes the display of the subject's body direction for which the confirmation input has been made.

By configuring the display unit 341 as described above, it is possible to confirm at a glance the body orientation and body temperature of a plurality of displayed infants, and also to see at a glance how much sleep has been checked. Therefore, it is possible to provide a sleep check system that can reduce the burden on users such as nursery teachers who have to check the sleep of a plurality of subjects at once in an afternoon nap check or the like.

In addition, under the control of the control unit 310, when the confirmation input of the operation input unit 351 is received, the display unit 341, if there is even one target person who remains in a predetermined body direction, An alert display may be displayed without changing the display of the orientation of the body. Specifically, in the afternoon nap check at a nursery school, if there is even one target whose infant's body orientation is prone, if the confirmation input is accepted and the display is changed, the check will be completed by mistake. There is a concern that check omissions may occur. In response to such a concern, the display unit 341 sets the predetermined body orientation to “face down”, and if there is even one child whose body orientation remains prone, Instead of changing the direction display all at once, an alert display with a message such as "There is a child sleeping on his stomach" may be displayed.

As an example, the display unit 341 may select and display the orientation of the subject's body to be displayed for each age of the subject, or for each age and age in months under the control of the control unit 310 . In nursery school afternoon nap checks, if there are children of different ages and ages in the same class, although it is okay to check every 10 minutes for children over 1 year old, the format is limited to the check form, and the same 5 as 0-year-old children There are cases where you have to check every minute. The operation of the sleep check differs depending on the nursery school, but there is no problem with checking every 10 minutes for children over the age of two.

For example, the display unit 341 displays the body orientation of the target display target for each age and month (for example, 0 years and several months, 1 year old, 2 years old, etc.) of the target kindergarten child, every 5 minutes if the child is 0 years old. By setting the orientation of the body as the object to be displayed, and by setting the orientation of the body every 10 minutes for a one-year-old to be displayed, it is possible to display only the amount of information to be appropriately checked, which contributes to reducing the burden on the user who checks. . In addition, by selecting and displaying on the display side, it is possible to cope with the problem without changing the detection interval set by the sensor device 400, so that it is possible to provide a highly versatile sleep check system.

Furthermore, as an example, the display unit 341 can select and display the orientation of the subject's body to be displayed based on the period of stay of the subject stored in the storage unit 330 under the control of the control unit 310. can. For example, when the sleep check system 100 is used to check a nap in a nursery school, children who have just entered the nursery school have unstable sleep, so regardless of age or age, check sleep frequently (for example, every 5 minutes). sometimes it's better to It is possible to select a check interval that is more suited to the actual situation than the selection of the check interval (selection of the orientation of the body to be displayed) according to the child's age or age in months.

As an example, the display unit 341 may change, under the control of the control unit 310, the display of the orientation of the body of the subject determined by the determination unit of each device to roll over frequently. Specifically, for example, the display unit 341 highlights an arrow display that is a display of the direction of the body of the subject determined to turn over frequently under the control of the control unit 310 (e.g., “tossing and turning abnormally frequently”). add a text display such as "It is", change the color from other arrows, make the border of the arrow thicker, blink it, change the size, etc.). With such a configuration, it is possible to notify the user such as a nursery teacher who checks sleep that the state of sleep is different from usual sleep, and to make the target kindergarten child aware that there is a high possibility that it is difficult to sleep. be able to. A user such as a nursery teacher can check the highlighted display, adjust the sleeping environment of the target child (for example, change the futon or blanket, etc.), and take preventive measures such as SIDS including sleeping on the stomach. be able to.

As an example, the display unit 341 may change, under the control of the control unit 310, the display of the orientation of the body of the subject for whom the determination unit of each device determines that the body temperature is not normal. Specifically, for example, the display unit 341 displays the body temperature (such as 37.0°) of the subject whose body temperature is determined to be not normal under the control of the control unit 310, and emphasizes it in the numerical display (for example, "body temperature is abnormally high.”, change the color from other numeric displays, make the letters bold, blink, change the size of the letters, etc.). By adopting such a configuration, it is possible to determine that there is a high possibility that the target infant is overheated (and that there is a high possibility of developing SIDS), and preventive measures such as SIDS including sleeping on the stomach. can do In addition, in the case of infants, if the temperature rises above the child's own body temperature due to the room temperature being too hot or wearing too many clothes during sleep, the autonomic nervous system will prioritize body temperature regulation and make breathing and heart movement. There are studies that show that the As research has shown that many cases of SIDS were caused by high fever due to poor physical condition or high fever due to stress due to admission to a nursery school for the first time, it is important whether the target infant was able to dissipate body temperature appropriately. It is also effective from this point of view to notify a user such as a nursery teacher that the body temperature has risen due to lying on the stomach.

As an example, the display unit 341 displays, under the control of the control unit 310, among the subjects grouped by the determination unit of each device, the number of people determined to turn over frequently or the number of people determined to have an abnormal body temperature. As a result of determining whether or not the number of people in one group is greater than the predetermined number, if it is determined that the number is greater than the predetermined number, display an alert prompting the user to change the sleep environment settings for the grouped target people collectively. may be displayed. For example, when the number of children whose body temperature is determined to be not normal is larger than the predetermined number of people, the display unit 341 displays the following message: "It seems that there are many children with abnormally high body temperatures. Please change the settings of." may be displayed in a pop-up. With such a configuration, it is possible to notify that many of the children sleeping in the same environment are sleeping differently than usual, and the overall sleeping environment is not appropriate for users such as nursery teachers. It can give you a sense of what is possible. A user such as a nursery teacher can check the alert display and adjust the overall sleeping environment of the target children (for example, change the heating and cooling settings, open the window, etc.), and can efficiently sleep. We can help you organize your environment.

In addition, the display unit 341 changes the display of the orientation of the body based on the child's enrollment period in the nursery school. Because it is short, it is possible to add an underline to the display of the name to distinguish it from the display of other children, or to display the display of the body orientation in a square box.

Under the control of the control unit 310, the display unit 341 also displays the orientation of the body based on the posture information for the child whose body orientation is “sleeping on the stomach” (in this example, “peach”). body direction detected at 13:25), a downward arrow may be displayed, and an alert display such as "<Warning> Momo is lying face down" may be displayed in a pop-up. Under the control of the control unit 310, the display unit 341 provides a “confirm” button in the pop-up display, and presses the button when the user such as a nursery teacher changes the posture of the target child from prone to supine.
