An information processing device comprising: a determination unit that determines an event related to an infant based on the information and body temperature information; and a registration unit that registers information indicating the event determined by the determination unit in a predetermined recording device. .

Based on the infant's body movements and the infant 's body temperature, this information processing device detects various events caused by the infant, such as the infant's excretion, rolling over, and movement by crawling, changing diapers, and monitoring family members. Various events performed on infants by users other than infants, such as holding infants in a standing position, holding them in a lying position, and moving them in a stroller, were determined as events related to infants. Automatically register events in a predetermined recording device.

As a result of such processing, the information processing device can automatically grasp the condition of an infant who is unable to speak, and can automatically register information indicating the grasped condition in a predetermined recording device. Therefore, the information processing device can acquire useful information regarding childcare and save time and effort related to information registration.

Further, the information processing device determines an action performed by the infant as an event related to the infant. For example, the information processing device determines excretion by an infant or sleep of an infant. Note that the information processing device may determine various events caused by the infant itself, such as the infant's rolling over, crawling, falling asleep, and waking up. As a result of such processing, the information processing device can acquire information useful for childcare, such as what actions the infant performed and at what timing.

Further, the information processing device determines that the infant has defecated when the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature rises indicated by the body temperature information satisfies a predetermined condition. As a result of such processing, the information processing device can hygienically and appropriately determine the infant's excretion.

Further, the information processing device determines whether the infant is sleeping based on the periodicity of the body temperature indicated by the body temperature information and the maximum value of the body temperature. Therefore, the information processing device can appropriately determine the infant's sleep pattern.

Further, the information processing device determines an action performed by another person toward the infant as an event related to the infant. For example, the information processing device determines, as an action performed by another person, an action of replacing an absorbent article worn by an infant or an action of picking up an infant. To give a more specific example, if the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature rises indicated by the body temperature information satisfies a predetermined condition, the information processing device It may be determined that the infant has been picked up. In addition, if the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature decreases indicated by the body temperature information satisfies a predetermined condition, the information processing device may replace the absorbent article of the infant with another person. It may be determined that the Therefore, the information processing device can record the frequency of changing absorbent articles such as diapers, the frequency of picking up infants, and the like.

Further, the information processing device identifies a pattern in which an event occurs. Therefore, the information processing device can provide various types of information according to patterns in which various events related to infants occur.

Further, the information processing device provides information according to the specified pattern to a user who has a predetermined relationship with the infant. For example, the information processing device provides information that visually indicates a pattern. Therefore, the information processing device can present to the user a pattern of events caused by the infant himself or a pattern of events caused by another person, such as changing a diaper.

Further, if the timing at which it is determined that the predetermined event has occurred deviates from the pattern in which the predetermined event occurs, the information processing device provides a notification that the occurrence of the predetermined event deviates from the pattern. Note that the information processing device acquires body movement information and body temperature information for each of the plurality of infants, determines events related to the infant for each infant, identifies patterns in which events occur for each infant, and performs a predetermined process. If the timing at which it is determined that the predetermined event occurs for an infant deviates from the average pattern in which the predetermined event occurs for other infants, a notification that the occurrence of the predetermined event deviates from the pattern is provided. It's okay. As a result, the information processing device can provide various types of information to parents so that, for example, various events related to infants occur in a predetermined pattern, so that the development of infants can be promoted.

The information processing device also acquires body movement information and body temperature information detected by a detection device attached to sandwich an end of the waist of an absorbent article worn by an infant. Therefore, the information processing device can easily attach the detection device to acquire the body movement information and body temperature information of the infant.

Below, an example of an information processing apparatus, an information processing method, an information processing program, and a form for implementing the system (hereinafter referred to as "embodiment") will be described in detail with reference to the drawings. Note that the information processing apparatus, information processing method, information processing program, and system are not limited to this embodiment. In addition, in the following embodiments, the same parts are given the same reference numerals, and redundant explanations will be omitted.

[Embodiment]
[1. About an example of the provision system]
First, an example of a providing system according to an embodiment will be described using FIG. 1. FIG. 1 is a diagram illustrating an example of a providing system according to an embodiment. As shown in FIG. 1, the providing system includes an information providing device 10, which is an example of an information processing device, and terminal devices 101 and 102 (hereinafter collectively referred to as "terminal devices 100") used by users UM and UF. ). Note that the providing system may include any number of information providing devices 10 and terminal devices 100. Further, the information providing device 10 may perform processing described below with an arbitrary number of terminal devices 100.

The information providing device 10 is an information processing device that performs information processing to be described later, and is realized by, for example, a server device, a cloud system, or the like. For example, the information providing device 10 supports various mobile communication systems such as LTE (Long Term Evolution), 4G (Generation) including LET-Advanced, which is a type of LET, and 5G, which will be standardized in the future; Communication is performed with the terminal device 100 via a network N (for example, see FIG. 5), such as various wireless communication networks such as (registered trademark) or wireless LAN (Local Area Network), or various wired communication networks.

The terminal device 100 is a terminal device used by a user U, and is realized by a smart device such as a PC (Personal Computer), a server device, a smart television, a smartphone or a tablet, and is connected to an information providing device via a network N. This is a mobile terminal device that can communicate with 10. In addition, the terminal device 100 has a screen such as a liquid crystal display, which has a touch panel function, and the information providing device 10 allows the user to perform tap operations, slide operations, scroll operations, etc. using a finger or a stylus, etc. It may have a function that can accept various operations on the content that is displayed.

Here, it is assumed that the terminal device 101 is a terminal device used by the user UM who is the mother of the infant B1. Further, it is assumed that the terminal device 102 is a terminal device used by a user UF who is the father of the infant B1. It should be noted that each terminal device may be used by a user who performs various activities for the infant B1, such as a brother, grandfather, relative, nurse, housekeeper, etc., in addition to the parents of the infant B1. It may be a terminal device used by any user.

[1-1. About events involving infants]
Here, in order to promote the growth of infants, it is considered useful to determine various events that occur in infants and to provide various proposals to parents etc. based on the determined events. For example, based on the date and time when an infant defecates, it is possible to estimate the infant's excretion pattern, which in turn makes it possible to suggest efficient timing for changing absorbent products (e.g., various types of diapers, etc.). It will be done.

In addition, it is possible to estimate the infant's sleep pattern from the date and time when the infant falls asleep and the date and time when the infant wakes up.Such sleep patterns can provide information such as when is the appropriate time to put the infant to bed, It is believed that it is possible to provide predictions about when infants will wake up, promoting appropriate sleep in infants and infants, promoting growth, and improving the quality of life for parents.

Further, from the date and time when the infant was held, it is possible to estimate the pattern and amount of holding. This kind of physical contact, such as holding, is thought to be useful for the development of infants and young children. Therefore, by providing parents with information indicating the pattern and amount of holding, physical contact such as holding can be promoted, and the development of infants and young children can be promoted. It is thought that this can be promoted.

In this way, by managing the history of various events related to infants, it is possible to promote the growth of infants and improve the quality of life of parents. However, manually recording the occurrence of events related to infants in this way is time-consuming.

Moreover, various events can be considered as events that occur regarding infants. For example, such events may include the infant defecating, the infant crawling, the infant rolling over, the infant falling asleep, the infant waking, or the infant's own breast feeding. Various events can be considered that occur due to the actions of people. In addition, such events include various events that occur due to user actions different from those of infants, such as changing absorbent articles worn by infants, holding infants in arms, and moving infants in strollers. I can do it. It takes time and effort to record such various events every time they occur.

[1-2. About information processing overview]
Therefore, the information providing device 10 executes the following information processing. First, the information providing device 10 acquires body movement information indicating the infant's body movement detected by a detection device attached to an article worn by the infant and body temperature information indicating the infant's body temperature. For example, the information providing device 10 acquires the body movements and body temperature of an infant through a detection device equipped with a thermometer, various acceleration sensors, and the like.

Here, when some kind of event occurs regarding an infant, it is thought that different characteristics will appear in the infant's body movements and the infant's body temperature depending on the type of event (that is, the content of the event). For example, when a typical mammal excretes, it is thought that the body stops moving because it has to strain. Furthermore, when an infant defecates into an absorbent article such as a diaper, it is thought that the humidity within the absorbent article increases, resulting in an increase in body temperature. Therefore, if the infant's body movements are below a predetermined threshold and the infant's body temperature rises (rapidly) above the predetermined threshold, it can be determined that the infant has defecated.

Therefore, the information providing device 10 determines an event that has occurred regarding the infant based on the acquired body movements and body temperature of the infant. For example, the information providing device 10 determines events caused by actions performed by the infant, such as the infant's excretion, falling asleep, or sleep, and events caused by actions performed by the user toward the infant, such as changing a diaper or holding the infant. The information providing device 10 then registers the determination result in a predetermined recording device.

In this manner, the information providing device 10 automatically determines an event that has occurred regarding an infant and registers information on the identified event in the recording device. As a result of such processing, the information providing device 10 can provide various useful information regarding childcare, for example.

Note that the information providing device 10 can determine various events based on body movements and body temperature. The details of such determination processing will become clear in the explanation to be described later.

[1-3. Regarding an example of prediction processing]
An example of information processing will be described below with reference to FIG. For example, in the example shown in FIG. 1, an infant B1 is wearing an absorbent article D. Here, the absorbent article D may be any absorbent article that is used by infants, such as a tape-type diaper or a pant-type diaper that is worn using tape.

Here, a wearable device WD is attached to the absorbent article D as a detection device that detects the body movements of the infant B1 (hereinafter collectively referred to as "body movements") and the body temperature of the infant B1. For example, the wearable device WD is an article that can be attached to or detached from any absorbent article D, and is attached to the absorbent article D so as to sandwich the ends of the waist.

An example of the wearable device WD will be described below with reference to FIGS. 2 to 4. FIG. 2 is a front view showing an example of the shape of the wearable device WD according to the embodiment. For example, in the wearable device WD, as shown in FIG. 2, a head part P1, a connecting part P2, and a rear part P3 are integrally formed of a soft and flexible material such as silicone resin.

The head part P1 has an opening H1 smaller than a sensor S, which will be described later, and is configured to be able to hold a sensor S, which will be described later, through the opening H1. Furthermore, magnets M1 and M2 are enclosed in the head part P1 and the rear part P3, which are arranged so that their magnetic poles with respect to the front are reversed. Therefore, the wearable device WD can be fixed to an object by bending the connection part P2 and sandwiching a part of the object between the head part P1 and the rear part P3.

FIG. 3 is a cross-sectional view showing an example of the shape of the wearable device WD according to the embodiment. Note that FIG. 3 shows an example of a cross-sectional view when the wearable device WD is cut along the line AA shown in FIG. 2.

As shown in FIG. 3, a sensor S for measuring the body temperature and body movements of an infant is enclosed in the head part P1 of the wearable device WD via an opening H1. For example, the sensor S has a main body made of various resins or metals, and is equipped with a body temperature sensor, an acceleration sensor, and various circuits for performing short-range wireless communication such as NFC (near field communication). Note that the sensor S may be waterproof, and may be provided with a circuit for wireless power supply or a circuit or terminal for wired power supply. Such a sensor S is enclosed in the head part of the wearable device WD via the opening H1.

Here, the opening H1 is provided so as to face the body side of the infant B1 when the connecting part P2 of the wearable device WD is bent. For example, FIG. 4 is a diagram illustrating an example of how the wearable device according to the embodiment is worn. For example, as shown in FIG. 4, by bending the wearable device WD so that the ends of the absorbent article D are sandwiched between the magnets M1 and M2, the electromagnetic EM generated by the magnets M1 and M2 moves the wearable device WD into the absorbent article. It is possible to fix it at D. At this time, the head part P1 in which the sensor S is enclosed is placed so as to be in contact with the body (for example, around the abdomen or side) of the infant wearing the absorbent article D. As a result of this arrangement, wearable device WD can appropriately measure the body temperature of infant B1. Note that the main body portion of the wearable device WD may be hollow or may be omitted.

In this way, the wearable device WD is a detection device that can be attached to or removed from various absorbent articles D, and measures the body temperature and body movements of the infant B1. Therefore, the wearable device WD can not only be attached to an absorbent article D of any size or manufacturer, but also can be attached to a new absorbent article D when replacing an absorbent article. , it is possible to continuously measure the body temperature and body movements of the infant B1.

Note that the configurations of the wearable device WD shown in FIGS. 2 to 4 are merely examples. For example, the wearable device WD may have a clip-shaped shape made of plastic. For example, the wearable device WD is equipped with a body temperature sensor in a range that comes into contact with the infant B1 (for example, the head part P1) when worn, and an acceleration sensor in a range that does not come into contact with the infant B1 (for example, the rear part P3). It may be equipped with.

It is assumed that the sensor S is equipped with an acceleration sensor capable of measuring acceleration in three axial directions with the sensor as a reference. Acceleration acquired using such an acceleration sensor will be shown in a measurement coordinate system based on the sensor, but the information providing device 10 uses the acceleration in such a measurement coordinate system to calculate the following: Processing may be performed, for example, by identifying the direction of gravity from the measured acceleration and performing various transformations using the identified direction of gravity, the acceleration in an absolute coordinate system based on the direction of gravity can be determined. , the following processing may be executed from the acceleration based on the specified absolute coordinate system.

Returning to FIG. 1, the explanation will be continued. Such a wearable device WD detects the body movement and body temperature of the infant B1 (step S1). For example, the wearable device WD detects acceleration in each axis direction as a body movement at predetermined time intervals (for example, in units of several seconds), and also detects body temperature. Wearable device WD then uses information indicative of detected body movement (i.e., acceleration value) as body movement information, which is associated with detection time, and information in which body temperature values are associated with detection time as body temperature information. Hold.

Wearable device WD then provides body movement information indicating body movement and body temperature information indicating body temperature to terminal device 101 used by user UM (step S2). For example, the wearable device WD transmits the body movement information and body temperature information it holds to the terminal device 101 via short-range wireless communication or the like.

In such a case, the terminal device 101 transmits the body movement information and body temperature information to the information providing device 10 (step S3). In such a case, the information providing device 10 estimates an event that has occurred regarding the infant based on the body movement information and body temperature information (step S4). For example, the information providing device 10 determines various events such as whether the infant has excreted the toilet or whether the user UM or the user UF has replaced an absorbent article based on body movements and body temperature measured at the same time. The information providing device 10 then determines the time at which each event occurred from the detection time associated with the body movement and body temperature. Thereafter, the information providing device 10 associates the determined event and time and registers them in a predetermined database.

Furthermore, the information providing device 10 identifies the pattern in which the event occurs for each type of event (step S5). For example, the information providing device 10 displays various excretion patterns such as how often infants defecate, what time they defecate, and what time each day they are likely to defecate. Calculate information indicating. The information providing device 10 may, for example, know at what time the user UM replaces the absorbent article D worn by the infant B1, the number of times the absorbent article D is replaced per day, its average value, and the time when the absorbent article D worn by the infant B1 is most likely to be replaced. The belt or the like may be calculated as information indicating the exchange pattern of the absorbent article.

Then, the information providing device 10 provides information according to the pattern to the user UM (step S6). For example, the information providing device 10 provides information indicating various patterns, such as time periods in which the infant B1 is likely to defecate.

Here, if the timing at which the predetermined event is determined to have occurred deviates from the pattern in which the predetermined event occurs, the information providing device 10 provides a notification to the effect that the occurrence of the predetermined event deviates from the pattern. It's okay. For example, the information providing device 10 compares the date and time when the absorbent article D was last exchanged with a pattern based on the date and time when the absorbent article D was exchanged up to that point. Then, if there is a discrepancy between the date and time when the absorbent article D was last exchanged and the pattern based on the date and time when the absorbent article D was exchanged up to then, the information providing device 10 determines whether the daily pattern is It is determined that the absorbent article D has been replaced with a different pattern. For example, the pattern of the time interval from when it is determined that the infant has defecated until the time when the absorbent article D is replaced, and the pattern of the time interval from when it is determined that the infant has defecated until the time when the absorbent article D is replaced. If the time intervals until the replacement is different, it may be determined that the absorbent article D has been replaced in a pattern different from the daily pattern. Further, the information providing device 10 may specify, for example, an average time interval from when an infant excretes to when the absorbent article D is replaced as a pattern.

Here, if the exchange pattern of the absorbent article D changes, there is a high possibility that the absorbent article D was exchanged by a different user. Therefore, the information providing device 10 sends information to the terminal device 102 used by the user UF, not the user UM, along with information indicating that the absorbent article D has been exchanged in a pattern different from the usual pattern. That is, information indicating a pattern of events (exchange of absorbent article D) by user UM, who is a mother, is provided (step S7).

Note that, for example, it may be determined which user is exchanging the absorbent article D by registering in advance (or acquiring schedule information, etc.) which of the users UF and UM is caring for the child. . For example, when the absorbent article D is exchanged in a different pattern than usual or when the absorbent article D is not exchanged, the information providing device 10 determines whether the absorbent article D is used in childcare based on a pre-registered schedule identify the person The information providing device 10 may then provide the identified user with an exchange pattern for the absorbent article D and a message urging exchange. In addition, the information providing device 10 may notify the user of the absorbent article D if the absorbent article D is not replaced after the infant defecates and until the time interval specified as the pattern has elapsed. A notification may be sent to prompt the replacement of the

In this way, the information providing device 10 determines various events that occur in the infant B1 from the body movements and body temperature detected by the detection device attached to the absorbent article worn by the infant B1, and records the determined events. In addition to automatically performing the following, it also provides users with information according to the event. Therefore, the information providing device 10 can promote the growth of the infant B1, reduce the trouble and anxiety of the users UM and UF regarding childcare, and improve the quality of their lives. In particular, infants and young children spend more time sleeping in their lives (percentage of sleeping hours per day, number of naps, etc.) than adults.In other words, the rhythm (pattern) of infants' daily lives has a large influence on the rhythm of sleep. This will have an impact. Therefore, by providing users with information according to events and event patterns, it is possible to stabilize the rhythm of life and adjust the sleep rhythm of infants, thereby promoting the development of infants and infants. Can be done.

[2. Regarding an example of functional configuration]
An example of a functional configuration for realizing the above-described selection process will be described below. In the following description, an overview of the functional configuration of the information providing apparatus 10 will be described, and then an example of a process performed by the functional configuration of the information providing apparatus 10 will be described.

[2-1. About the overview of the functional configuration of the terminal device 100]
FIG. 5 is a diagram illustrating an example of a functional configuration of a terminal device according to an embodiment. As shown in FIG. 5, the information providing device 10 includes a communication section 20, a storage section 30, and a control section 40.

The communication unit 20 is connected to the network N by wire or wirelessly, and transmits and receives information to and from the terminal device 100. For example, the communication unit 20 is realized by a communication circuit or the like.

The storage unit 30 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk, and various data for executing output processing is registered. be done. For example, in the example shown in FIG. 2, a wearer database 31 and a user database 32 are registered in the storage unit 30.

In the wearer database 31, information regarding a wearer (that is, an infant) who wears the absorbent article D is registered. That is, the wearer database 31 registers information on users who are targets of event determination. For example, FIG. 6 is a diagram showing an example of information registered in the wearer database according to the embodiment. As shown in FIG. 6, in the wearer database 31, a wearer ID (Identifier), a responder ID, pattern information, and sensor information are registered in association with each other. Here, information having items such as date and time, body temperature information (temperature), and body movement information (x, y, z) is registered as sensor information in the wearer database 31. Further, each body movement information is associated with information having an item such as "determination information". In addition to the information shown in FIG. 6, the wearer database 31 may also register various sensor data acquired from the wearer and information regarding the wearer.

Here, the "wearer ID" is an identifier for identifying the wearer. Further, the "responder ID" is an identifier for identifying a user who performs various actions toward the wearer, such as exchanging absorbent articles, and is, for example, a user ID described later. Further, pattern information is information indicating patterns of various events determined from sensor information.

Further, the "date and time" is information indicating the date and time when the body temperature indicated by the body temperature information and the body movement indicated by the body movement information were detected, and is, for example, information indicating the detection date and time. Moreover, "body temperature information" is information indicating the wearer's body temperature (for example, degrees Celsius) detected by the sensor S. Moreover, "body movement information" is information indicating acceleration (for example, G) in each axis direction detected by the sensor S. Moreover, "judgment information" is information indicating an event that was determined to have occurred in an infant when the associated sensor information was acquired.

For example, in the example shown in FIG. 6, wearer ID "UID#1", correspondent ID "M#1, F#1", and pattern information "pattern #1" are registered in the wearer database 31 in association with each other. has been done. Such information indicates that the user who performs various actions toward the wearer indicated by the wearer ID "UID#1" is the user indicated by the responder ID "M#1, F#1", and the wearer This indicates that the pattern of various events related to is the pattern indicated by the pattern information "Pattern #1".

In the example shown in FIG. 6, the wearer database 31 includes, for the wearer ID "UID#1", the date and time "2019/05/01/10:15:25", the body temperature information "37.2", Body movement information "(0.5, 0.2, 0.2)" and determination information "hugging" are registered in association. Such information indicates that the body temperature of the wearer indicated by the wearer ID "UID #1" measured at 10:15:25 on May 1, 2019 was "37.2" degrees, and the body temperature in each axis direction was "37.2" degrees. The acceleration is (0.5, 0.2, 0.2), and when such sensor information is acquired, the event determined to be occurring in the infant is "holding". .

In addition, although the example shown in Figure 6 shows conceptual information such as "pattern #1," it actually includes the type of event, the date and time when the event occurred, the average frequency at which the event occurs, and the event Numerical values and character strings indicating patterns of various events, such as time periods in which events are likely to occur, will be registered.

Information regarding users who perform various actions toward the wearer is registered in the user database 32. For example, FIG. 7 is a diagram showing an example of information registered in the user database according to the embodiment. As shown in FIG. 7, information such as a user ID, terminal information, and related information is registered in the user database 32. In addition to the information shown in FIG. 7, the user database 32 may also register arbitrary information regarding users who perform various actions toward the wearer.

Here, the "user ID" is an identifier for identifying a user. Moreover, "terminal information" is information for identifying the terminal device 100 used by the user indicated by the associated user ID. Moreover, "relationship information" is information which shows the relationship between the user indicated by the matched user ID, and the wearer indicated by the wearer ID linked with the user ID.

For example, in the example shown in FIG. 7, information such as user ID "M#1", terminal information "T#1-1", and related information "mother" are registered in the user database 32 in association with each other. There is. Such information indicates that the user indicated by the user ID "M#1" is using the terminal device 100 indicated by the terminal information "T#1-1". In addition, such information is provided by the user indicated by the user ID "M#1" and the wearer ID "UID#1" associated with the user ID "M#1" in the wearer database 31. Indicates that she is the wearer's "mother."

Returning to FIG. 5, the explanation will be continued. The control unit 40 is, for example, an arithmetic processing device for executing various types of processing, and is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), etc., and a predetermined storage device (for example, the storage unit 30). This is realized by executing various programs (corresponding to an example of an output program) stored in the RAM using the RAM as a work area. Further, the control unit 80 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

In the example shown in FIG. 5, the control unit 40 includes an acquisition unit 41, a determination unit 42, a registration unit 43, a specification unit 44, and a provision unit 45, and executes information processing described below.

[2-2. About information processing]
An example of information processing executed by the control unit 40 will be described below with reference to FIG. 8. FIG. 8 is a flowchart illustrating an example of the process flow of the information providing apparatus 10 executed by the information providing apparatus according to the embodiment.

For example, the acquisition unit 41 determines whether it is a predetermined processing timing (step S101). For example, when receiving various sensor information such as body movement information and body temperature information from the terminal device 100, the acquisition unit 41 determines that it is processing timing. Then, if it is not the predetermined processing timing (step S101: No), the acquisition unit 41 waits until the predetermined processing timing. Then, if it is a predetermined processing timing (step S101: Yes), the acquisition unit 41 acquires various sensor information from the terminal device 100 (step S102).

Here, the acquisition unit 41 acquires body movement information indicating the infant's body movement detected by a detection device attached to an article worn by the infant and body temperature information indicating the infant's body temperature. For example, the acquisition unit 41 acquires body movement information and body temperature information from a wearable device WD attached to sandwich an end of the waist circumference of the absorbent article D. Note that the acquisition unit 41 may register the acquired sensor information in the wearer database 31.

Subsequently, the determination unit 42 determines an event that has occurred regarding the infant based on the sensor information (step S103). For example, the determining unit 42 determines the details of an event that occurred in an infant based on body movements and body temperature detected at the same time. More specifically, the determination unit 42 identifies the body temperature indicated by the body temperature information and the body movement indicated by the body movement information whose detection date and time are the same at the same time (for example, within a range of several seconds to several minutes), and determines the change in body temperature. Based on whether or not the changes in body movements and body movements satisfy a predetermined condition, an event that occurred in the infant at that time is determined. For example, the determination unit 42 determines an action performed by the infant as an event related to the infant. To give a more specific example, the determination unit 42 determines the excretion by the infant or the sleep of the infant.

For example, when an infant defecates into the absorbent article D, the infant's body movements decrease and the infant's body temperature rises rapidly. Therefore, when the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature rises indicated by the body temperature information satisfies a predetermined condition, the determination unit 42 determines that the infant has excreted the toilet. For example, the determination unit 42 determines that the period in which the body movement information is within a predetermined range (e.g., the amount of variation in each axis direction is equal to or less than a predetermined threshold) continues for a predetermined period (e.g., several tens of seconds), and If the amount or rate of increase in body temperature within a predetermined period including the period exceeds a predetermined threshold, it is determined that the infant has excreted excretion during that period.

Note that when such a determination is made, the information providing device 10 may detect the excretion of an infant even if the wearable device WD is placed at a position away from the part of the absorbent article that absorbs excrement. Can be done. Therefore, the information providing apparatus 10 can keep the repeatedly used wearable device WD sanitary.

Here, in order to promote the growth of infants, it is considered effective to maintain the sleep rhythm of infants. Therefore, it is believed that if the appropriate time for infants to fall asleep is detected and the detected information is provided to users, it will be possible to encourage infants to sleep in an appropriate rhythm and promote their development. It will be done. Therefore, the determining unit 42 may determine the appropriate time period for the infant to fall asleep.

For example, when an infant falls asleep, it is estimated that the infant's body movements decrease, and the infant's body temperature gradually increases toward the time of falling asleep, and after falling asleep, the infant's body temperature gradually decreases. Additionally, infants are generally considered to sleep at night. Therefore, the determining unit 42 determines whether the infant is sleeping based on the periodicity of the body temperature indicated by the body temperature information and the maximum value of the body temperature. For example, the determination unit 42 identifies the cycle of body temperature fluctuation indicated by the body temperature information every 24 hours. Then, the determination unit 42 determines that the infant has fallen asleep at the timing when the maximum value of body temperature during the night is measured. Note that the determining unit 42 may determine that the infant has woken up at a timing when the rate of increase in body temperature in the morning exceeds a predetermined threshold.

Further, the determination unit 42 may determine the pattern of the time period in which the infant falls asleep. Furthermore, based on the periodicity and maximum value of body temperature, a predetermined time before the maximum value may be determined as the appropriate time to fall asleep. That is, the determination unit 42 may determine the appropriate time period for putting the infant to sleep based on the periodicity and maximum value of body temperature.

Further, the determination unit 42 may determine whether the infant is sleeping or not, taking into consideration the body movement indicated by the body movement information. For example, the determining unit 42 determines that the infant has fallen asleep at the timing when the maximum value of the body temperature is measured in the periodicity of the body temperature indicated by the body temperature information and the body movement indicated by the body movement information becomes equal to or less than a predetermined threshold. You may. Furthermore, if the body movement exceeds a predetermined threshold at the time determined to be the appropriate time to fall asleep, it may be determined that a notification or information to encourage falling asleep is to be provided. That is, if the body movement indicated by the body movement information satisfies a predetermined condition at the appropriate time for falling asleep determined from the periodicity and maximum value of body temperature, the determining unit 42 determines that appropriate sleep onset has not been performed. Good too. Further, similarly to the appropriate time for falling asleep, the determining unit 42 may determine a pattern of time slots in which infants wake up (wake-up pattern) and an appropriate wake-up time that is an appropriate time for waking up.

In addition, it is thought that infants and toddlers turn over while sleeping. Therefore, the determination unit 42 determines the timing when the infant turns over, for example, by comparing the characteristics of body movement information measured in advance when turning over with the characteristics of the acquired body movement information. May be specified. Further, the determining unit 42 may determine whether the baby has turned over or not based on body movements detected during a time period in which it has been determined that the infant is sleeping.

In addition to the events described above, the determining unit 42 may determine various events that occur due to the infant's own actions. For example, the determination unit 42 determines various events such as an infant crawling or an infant drinking breast milk, depending on whether body temperature information and body movement information satisfy predetermined conditions. Good too.

Further, the determining unit 42 determines an action performed by another person toward an infant as an event related to the infant. For example, the determining unit 42 determines an action performed by another person, such as replacing an absorbent article worn by an infant or picking up an infant.

For example, when replacing an absorbent article worn by an infant, the infant's body temperature may drop dramatically and the infant's body movements may fall below a predetermined threshold. Therefore, if the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature decreases indicated by the body temperature information satisfies a predetermined condition, the determination unit 42 determines that someone else replaces the infant's absorbent article. It may be determined that the

Further, when a user picks up an infant, it is thought that an acceleration of a predetermined value or more is applied to the infant, and thereafter, fluctuations in body movement become smaller. Further, when a user picks up an infant, the infant's body temperature is thought to rise because the user and infant are in close contact with each other. Therefore, if the body movement indicated by the body movement information falls within a predetermined range and the manner in which the body temperature rises indicated by the body temperature information satisfies a predetermined condition, the determination unit 42 determines that another person has picked up the infant. Good too.

Note that the determining unit 42 may determine whether the infant is being held in a standing position or in a sleeping position, depending on the body movement indicated by the body movement information. For example, the determining unit 42 may determine whether the infant is standing or sleeping based on the acceleration in each axis direction acquired as body movement information.

In addition to the events described above, the determining unit 42 may also determine events based on actions performed by the user toward infants. For example, the determination unit 42 may determine various events such as moving an infant in a stroller. In order to judge such an event, for example, the type of event and the characteristics of the body temperature and body movement that will be measured when the event occurs are stored in advance, and the body temperature and body movement indicated by the body temperature information are stored in advance. This can be achieved by determining whether the body movement indicated by the body movement information has the characteristic.

Note that the determination unit 42 may determine events based on rules such as whether or not body movements and body temperature satisfy predetermined conditions. The above-mentioned determination may be realized using a model that has learned the relationship between body temperature and body movement characteristics that may occur.

For example, the determination unit 42 learns to output information indicating the event when body movement information indicating body movement and body temperature information indicating body temperature that were acquired when a certain event occurred are input. Get the model where the was done. Then, the determination unit 42 may input the body temperature information and body movement information to the model to determine the event that occurred in the infant when the body temperature information and body movement information were acquired. .

Any type of model can be adopted as such a model. For example, the information providing device 10 may employ SVM (Support Vector Machine) or DNN (Deep Neural Network) as a model. Here, the DNN may be a CNN (Convolutional Neural Network) or an RNN (Recurrent Neural Network). Further, the RNN may be LSTM (Long short-term memory) or the like. Further, the model may be realized by combining a plurality of models, such as a model combining CNN and RNN. Note that when determining and recording events using such a learning model, it is preferable to accept whether the recorded event input by the user is correct or incorrect. Thereby, the learning model can be updated using the input correctness or incorrectness.

The registration unit 43 registers the determination result in the database (step S104). For example, the registration unit 43 registers information indicating the event determined by the determination unit 42 in the wearer database 31 as determination information. For example, if the event determined from the sensor information acquired within a certain period is "hug", the registration unit 43 may associate the determination information "hug" with the sensor information acquired within this period. Become.

The identifying unit 44 identifies a pattern in which an event occurs based on the estimation result (step S105). For example, the specifying unit 44 refers to the wearer database 31 and specifies the commonality of time periods in which predetermined events occur, commonality of intervals, etc., thereby specifying patterns in which events of the same type occur. Note that the specifying unit 44 may specify, for example, the total amount of time the baby was held, the frequency at which the baby was held, etc. as the pattern in which the event occurred.

The providing unit 45 generates provided information according to the identified event and event pattern (step S106). The providing unit 45 then provides the provided information to the parent of the infant (step S107).

For example, the providing unit 45 may provide information indicating the determined event and information indicating the time period in which the event occurred to a user who has a predetermined relationship with the infant, such as a parent or babysitter. Further, the providing unit 45 may provide information according to the specified pattern to a user who has a predetermined relationship with the infant.

For example, FIG. 9 is a first diagram showing an example of information provided by the information providing device according to the embodiment. For example, the providing unit 45 determines an event in which the infant is picked up by a user among events that occur regarding the infant, and also specifies a pattern in which the infant is picked up. Then, the providing unit 45 provides the user with information depending on whether or not the total number of times the user was picked up within 24 hours, the total amount of time that the user was picked up, and the interval between the time periods at which the user was picked up satisfy predetermined conditions. provide.

For example, if the holding time is less than 15 minutes, the providing unit 45 may say "a little", if the holding time is 15 minutes or more and less than 30 minutes, it may be "fair", and if the holding time is 30 minutes or more and less than 45 minutes, the providing unit 45 may give "a little". The evaluation is determined according to the holding time, such as "fair", "considerable" if it takes 45 minutes or more but less than 60 minutes, and "a lot" if it takes more than 60 minutes. Then, as shown in FIG. 9, the providing unit 45 generates content C10 indicating an evaluation of the holding time (for example, "quite a lot"), and provides the content C10 to the user.

Further, the providing unit 45 may provide information indicating the replacement timing of the absorbent article estimated according to the specified pattern. For example, FIG. 10 is a second diagram showing an example of information provided by the information providing device according to the embodiment. In the case shown in FIG. 10, the providing unit 45 specifies the time period when the infant is sleeping and the time period when the infant is awake, and generates content C20 indicating the specified time period. For example, the providing unit 45 generates the content C20, which includes a bar graph showing each hour of the day, in which the sleeping time period is shown in white and the awake time period is shown in hatching.

Furthermore, the providing unit 45 generates content C20 that shows an icon indicating the timing at which the infant has excreted, together with a bar graph, as the excretion timing. For example, the providing unit 45 estimates the appropriate exchange timing for the absorbent article from the specified excretion timing. For example, the providing unit 45 estimates the appropriate exchange timing of the absorbent article based on the timing of excretion, the timing pattern, the number of excretions that one absorbent article can handle (for example, two times), etc. do. Then, the providing unit 45 generates content C20 that shows information indicating the specified exchange timing together with a bar graph and excretion timing. The providing unit 45 may then provide the generated content C20 to the user.

For example, if the number of excretions that can be handled by the absorbent article is two, the providing unit 45 specifies the number of times the infant has excreted since the last time the absorbent article was replaced, and determines that the specified number of times is two. If this is the case, an alert may be provided to the user.

Further, the providing unit 45 may provide information visually indicating the specified pattern. For example, FIG. 11 is a third diagram showing an example of information provided by the information providing device according to the embodiment. For example, the providing unit 45 estimates a time when an infant is likely to fall asleep and a time when an infant is likely to wake up, based on the cycle of body temperature indicated by the infant's body temperature information. Then, the providing unit 45 generates and provides content C30 that includes information indicating a time when an infant is likely to fall asleep and a time when an infant is likely to wake up, along with a graph indicating a cycle of body temperature indicated by the infant's body temperature information. Good too.

Here, in order to promote the growth of infants, it is considered effective to maintain the infant's daily rhythm such as excretion, sleeping, and picking up the infant. For example, if user UF attempts to replace the absorbent article at a timing different from the timing at which user UM replaces the absorbent article, there is a risk that it will stress infant B1 and cause a shift in bedtime. be. Therefore, if the timing at which it is determined that the predetermined event has occurred deviates from the pattern in which the predetermined event occurs, the providing unit 45 may provide a notification that the occurrence of the predetermined event deviates from the pattern. good. For example, if the occurrence time of an event for exchanging a certain absorbent article deviates from the pattern of the event for exchanging an absorbent article, the providing unit 45 provides the users UM and UF with this fact. Good too.

Further, in addition to the information described above, the providing unit 45 may provide information regarding various events determined by the determining unit 42, and may provide information indicating patterns of various events identified by the identifying unit 44. It's okay. Further, the providing unit 45 may provide various types of information depending on the number and frequency of determined events, the results of comparison between the timing of each event and the pattern, and the like.

For example, the providing unit 45 may provide information indicating an appropriate time for falling asleep determined from the periodicity or maximum value of body temperature. Furthermore, if it is determined that the person is not falling asleep properly, the providing unit 45 may provide information indicating this fact. For example, if the body movement indicated by the body movement information at the appropriate time for falling asleep satisfies a predetermined condition, the providing unit 45 may provide a message suggesting that the infant be calmed and put to sleep.

[3. Regarding processing variations]
Hereinafter, variations of the above-mentioned processing will be explained. Note that the output processing described below may be performed individually or in any combination.

[3-1. Regarding processing that takes into account events of other infants]
In the above description, the information providing device 10 determines the event that occurred regarding a predetermined infant and provides information according to the determination result. However, embodiments are not limited thereto. For example, the information providing device 10 may determine events that have occurred regarding a plurality of infants and provide information according to the determination results.

For example, the information providing device 10 acquires body movement information and body temperature information for each of a plurality of infants. Then, the information providing device 10 determines events related to infants for each infant, and identifies patterns in which events occur for each infant.

Further, the information providing device 10 identifies an average pattern in which a predetermined event occurs for each infant. For example, the information providing device 10 specifies an average time period when all infants go to bed as an average pattern. Then, if the time when an infant goes to bed deviates from the average time, the information providing device 10 notifies the infant's parents, etc. that the sleeping pattern deviates from the average. Good too.

As a result of such processing, the information providing device 10 may notify that the occurrence timing or pattern of an event whose derived timing or pattern can be averaged, such as bedtime or wake-up time, deviates from the average. Therefore, the development of infants can be further promoted.

[3-2. About the executing body]

Further, the terminal device 100 may register the determination result in a storage device within the terminal device 100, or may register it in a storage area on various networks such as a cloud server, for example.

[3-3. About applicable targets]
In the example described above, the information providing device 10 determined various events that occurred in the infant based on sensor information detected by the wearable device WD attached to the absorbent article worn by the infant. However, embodiments are not limited thereto. For example, the information providing device 10 uses sensor information detected by a wearable device WD attached to an absorbent article or clothing worn by a cared person who needs care to determine various events that occur in the cared person. You may.

[3-4. Utilization of posture sensor]
In the above-mentioned system, an embodiment has been described in which a temperature sensor and an acceleration sensor are mainly used as sensors. It's okay. Note that, like the acceleration sensor, the angular velocity sensor in the wearable device WD may be placed in the same position as the temperature sensor, or may be placed in a different position.

The information providing device 10 preferably manages information that associates information regarding the detected posture with the detection time as posture information together with body movement information and body temperature information. Then, the information providing device 10 may determine a holding event based on the body movement information, body temperature information, and posture information. As a result, it may be determined that the baby is being held in a hug based on the fact that the baby is in a standing position and the body movement vibrates in a periodic rhythm and the body temperature rises. Also, using posture information, it is possible to determine whether the baby is being held in an upright position or lying down.

In this way, by acquiring more detailed information about carrying, you can, for example, provide users with information on child-rearing behavior such as ``recommended holding methods'' and ``if you tend to carry on your side, we recommend a sling,'' and Information about supplies can be provided. Furthermore, information to be provided to the terminal used by the father can also be determined using, for example, information on holding the baby identified by information acquired by the terminal used by the mother. This makes it possible to share information about how to hold the child, such as ``Mom always holds the child next to her.''

Note that the measurement target is not limited to angular velocity, and may be a sensor that measures angle, angular acceleration, direction, etc., as long as the sensor can detect or calculate the posture of an infant. Further, the information providing apparatus 10 may estimate the gravity direction from the measurement result of the acceleration sensor based on the installation direction of the wearable device WD, and may estimate the infant's posture from the estimation result. Further, the information providing device 10 may estimate the infant's body movement from the measurement results of the angular velocity sensor and the angle sensor. That is, the information providing device 10 may detect or estimate various information regarding the infant, such as the infant's body movement, posture, and body temperature, based on information measured by an arbitrary sensor.

[3-5. others〕
Note that among the above-described processes, all or part of the processes described as being performed automatically may be performed manually. Further, all or part of the processing described as being performed manually may be performed automatically by a known method. In addition, information including the processing procedures, specific names, and various data and parameters shown in the above documents and drawings may be changed arbitrarily, unless otherwise specified. For example, the various information shown in each figure is not limited to the illustrated information.

Furthermore, each component of each device shown in the drawings is functionally conceptual, and does not necessarily have to be physically configured as shown in the drawings. That is, the specific form of distributing and integrating each device is not limited to what is illustrated. In addition, all or part of each component may be functionally or physically distributed and integrated in arbitrary units depending on various loads and usage conditions. Furthermore, the above-described processes may be executed in combination as appropriate to the extent that they do not contradict each other.

[4. Hardware configuration]
Further, the information providing apparatus 10 according to the embodiment described above is realized by, for example, a computer 1000 having a configuration as shown in FIG. 12. FIG. 12 is a diagram showing an example of the hardware configuration.

The cache 1040 is a cache, such as a RAM, that temporarily stores data used by the arithmetic unit 1030 for various calculations. Further, the memory 1050 is a storage device in which data used by the arithmetic unit 1030 for various calculations and various databases are registered, and is realized by ROM (Read Only Memory), HDD (Hard Disk Drive), flash memory, etc. memory.

The output IF 1060 is an interface for transmitting information to be output to an output device 1010 that outputs various information such as a monitor or a printer, and is, for example, a USB (Universal Serial Bus), a DVI (Digital Visual Interface), It may be realized by a connector of a standard such as HDMI (registered trademark) (High Definition Multimedia Interface). On the other hand, the input IF 1070 is an interface for receiving information from various input devices 1020 such as a mouse, a keyboard, and a scanner, and is realized by, for example, a USB or the like.

For example, the input device 1020 may be an optical recording medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a PD (Phase change rewritable disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, It may be realized by a device that reads information from a magnetic recording medium, a semiconductor memory, or the like. Further, the input device 1020 may be realized by an external storage medium such as a USB memory.

The network IF 1080 has a function of receiving data from other devices via the network N and sending it to the computing device 1030, and also transmitting data generated by the computing device 1030 to the other devices via the network N.

Here, the arithmetic device 1030 controls the output device 1010 and the input device 1020 via the output IF 1060 and the input IF 1070. For example, the arithmetic device 1030 loads a program from the input device 1020 or the memory 1050 onto the cache 1040, and executes the loaded program. For example, when the computer 1000 functions as the information providing device 10, the arithmetic unit 1030 of the computer 1000 realizes the functions of the control unit 140 by executing a program loaded onto the cache 1040. Further, when the computer 1000 functions as the terminal device 100, the arithmetic unit 1030 of the computer 1000 acquires various sensor information from the wearable device WD by executing a program (application) loaded on the cache 1040, This realizes a function of transmitting sensor information to a computer functioning as the information providing device 10.

That is, the applied system includes programs installed in various information processing devices such as the information providing device 10 and applications installed in the terminal device 100. An application installed in such a terminal device 100 collects body movement information indicating the infant's body movement detected by a detection device (for example, a wearable device WD) attached to an article worn by the infant and the infant's body temperature. Obtain body temperature information. Further, a program installed in such an information processing device includes a determination procedure for determining an event related to an infant based on body movement information and body temperature information acquired by the terminal device 100, and an event determined by the determination procedure. This causes the information processing device to execute a registration procedure for registering information indicating the information in a predetermined recording device.

[5. effect〕
