<Configuration>
FIG. 1 is a block configuration diagram showing an information processing system 1 according to an embodiment of the present disclosure. In this information processing system 1, for example, the management server 100 receives user measurement data from the measurement device 300 via the network NW at predetermined periodic timings, and performs predetermined calculations on the measurement data. biometric data and generates a predetermined notification based on the biometric data.

The information processing system 1 has a management server 100, a user terminal device 200, a measuring device 300, and a network NW. The management server 100 and the user terminal device 200 are connected via a network NW. The network NW includes the Internet, an intranet, a blockchain network, a wireless LAN (Local Area Network), a WAN (Wide Area Network), BLE (Bluetooth Low Energy), and the like.

The management server 100 is, for example, a device that receives user measurement data from the measurement device 300 via a network at predetermined periodic timing via the user terminal device 200 and performs calculation from the measurement data to biometric data. There is, for example, a server device that provides various Web services.

The user terminal device 200 is an information processing device such as a personal computer, a tablet terminal, a smart phone, a smart watch, a mobile phone, a PHS, a PDA, etc. owned by a predetermined user. It is used to display data as a waveform graph or the like, or to display a predetermined notification (details will be described later) generated based on biometric data. User information such as user identification number, date of birth, gender, height, weight, stride length, etc. is registered in advance in the user terminal device 200, and user information including age calculated from the date of birth is measured data. to the management server 100 via the network NW.

Also, the user terminal device 200 may be configured such that the user inputs the state of data acquisition by the measuring device 300 using a touch panel or the like. The user terminal device 200 can input the 'data acquisition state' as tag information, for example, 'running' when running or 'eating' when eating. In this case, the user terminal device 200 associates the measurement data received from the measurement device 300 with predetermined periodic timing with the tag information and transmits it to the management server 100 via the network NW.

The measuring device 300 is a device that measures a user's biological data, and is a so-called wearable device that the user wears on his or her body such as a wrist or arm. This measurement device 300 is a device for measuring, for example, the user's electrocardiogram, pulse wave, skin temperature (body temperature), acceleration, and angular velocity data at predetermined periodic timings using a known method. The predetermined cycle may be set in advance or may be arbitrarily set by the user. More specifically, for example, a time period in units of seconds may be set, or the same may be set depending on the frequency.

As a specific example of the configuration of the measurement device 300, two electrodes may be brought into contact with the skin, and an electrocardiogram may be obtained as electrocardiogram data from changes in the detected potential difference over time. The waveform may be data obtained by galvanic skin response. In addition, the skin is irradiated with light from LEDs that emit green, red, and infrared light, and the change in intensity of the light received by the photodiode over time changes the volume of blood vessels caused by the heartbeat of the user, generating a pulse wave. It may be configured with a device that acquires pulse waveform data, and the pulse waveform that can be detected by this method is a photoelectric volume pulse waveform. Alternatively, the apparatus may be configured by a device that acquires the user's skin temperature as data from a temperature sensor that is brought into contact with the user's skin. Further, it may be composed of a three-axis acceleration sensor that detects the deformation state of each of the orthogonal XYZ axes, acquires the user's motion as acceleration data, and for example, the measuring device 300 is worn on the user's wrist, arm, or the like. In this case, the measurement device 300 acquires acceleration data as acceleration obtained by synthesizing the swing of the wrist or arm and the movement of the whole body. Furthermore, it may be composed of a gyro sensor (angular velocity sensor) that detects rotational angular velocities in each of the orthogonal XYZ axes. If so, the measurement device 300 acquires angular velocity data as an angular velocity obtained by synthesizing the rotation of the wrist, arm, etc. and the movement of the whole body.

Between the user terminal device 200 and the measuring device 300, Bluetooth (registered trademark), Near Field radio Communication (NFC), Afero (registered trademark), Zigbee (registered trademark), Z-Wave (registered trademark) ), or a wireless LAN or the like. A wired connection may be used instead of such a wireless connection. In addition, the user terminal device 200 and the measurement device 300 may be integrated equipment, for example, the measurement device 300 may be equipped with a SIM to have a communication function, or a management server using BLE (Bluetooth Low Energy). 100 may be configured to be directly communicable.

One or a plurality of user terminal devices 200 are connected to the network NW for the number of users using the measuring device 300 . One or a plurality of measuring devices 300 are connected to the same number of user terminal devices 200 used by one user. When one user uses multiple measuring devices 300 , multiple measuring devices 300 are connected to one user terminal device 200 .

<Management Server 100>
FIG. 2 is a diagram showing the hardware configuration of the management server 100. As shown in FIG. FIG. 3 is a block diagram illustrating functions of the storage unit 120 and the control unit 130. As shown in FIG. Note that the illustrated configuration is an example, and other configurations may be employed.

The management server 100 includes a communication unit 110 , a storage unit 120 , a control unit 130 and an input/output unit 140 . These functional units are realized by executing a predetermined program for the management server 100. FIG.

The communication unit 110 is a communication interface for communicating with the user terminal device 200, and communication is performed according to a communication protocol such as TCP/IP (Transmission Control Protocol/Internet Protocol).

The storage unit 120 stores programs, input data, and the like for executing various control processes and functions in the control unit 130, and is composed of RAM (Random Access Memory), ROM (Read Only Memory), and the like. be. Further, as shown in FIG. 3, the storage unit 120 includes a measurement data DB 121 that stores data measured by the measurement device 300 in association with user information, and a biometric data that is calculated and generated from the measurement data in association with the user information. , a notification information DB 123 that stores various notifications sent to the user terminal device 200, and a user information DB 124 that stores user information including user identification numbers. The user information may include account information generated by the data management unit 131, and the user information DB 124 may store the account information in association with other user information. Furthermore, the storage unit 120 temporarily stores data communicated with the user terminal device 200 . Note that the data structure of the DB is not limited to this, and part of the DB described above may be stored in the user terminal device 200 or the measurement device 300 .

The control unit 130 controls the overall operation of the management server 100 and includes a CPU (Central Processing Unit) and the like. Further, as shown in FIG. 3, the control unit 130 includes functional units such as a data management unit 131, a biometric data generation unit 132, a notification generation unit 133, and a data output unit .

Data management unit 131 generates account information for each user who uses measuring device 300 . This account information generation is performed when the user using the measuring device 300 registers the account information with the user terminal device 200 . Therefore, the data management unit 131 controls access to various DBs in the storage unit 120 for each account of the user terminal device 200 and other terminal devices of the user. The data management unit 131 stores various data such as measurement data and biometric data in a corresponding DB in association with user information. Also, at this time, the data management unit 131 can store the measurement data in association with predetermined tag information.

FIG. 4 is a schematic diagram showing an example of tag information associated with the measurement data of FIG. Data D1 shown in FIG. 4 is measurement data of the measurement device 300 . The tag T1 is tag information associated with the data D1. For example, time information when the measuring device 300 measured the data D1 or time information when the data D1 was transmitted from the measuring device 300 to the user terminal device 200 is time-series. stored as data. Alternatively, both the measured time information and the transmitted time information may be associated. For example, in the first line of the tag T1 shown in FIG. 4, "20180620120746144" is stored, which indicates June 20, 2018 12:07:46:144 milliseconds. Such time information can be obtained from communication logs. This makes it possible to ascertain which time period the measurement data belongs to.

It should be noted that the association between the measurement data and the biometric data using such tag information is not limited to the time information, and the physical information and behavior information indicating the user's physical condition and behavior can be entered freely and stored as tag information. (For example, in response to the question "How are you feeling now?", select one of "1: good, 2: normal, 3: bad", etc.) , the selected answer may be stored. Alternatively, when the user takes a predetermined action (for example, sitting, standing, walking, running, sleeping, eating, driving, resting, etc.), the user records measurement data or biometric data as tag information (for example, It may be a choice format or free description). Furthermore, instead of or in combination with the recording by the user, for example, measurement data and biological data (for example, walking speed information, stride length information, movement information of the wearing part, posture information, position information of the center of gravity, heartbeat information, etc. ), tag biometric data etc. by estimating predetermined behavior (for example, sitting, standing, lying down, walking, running, sleeping, waking up, going to bed, eating, driving, resting, etc.) by a known method You may associate as information (behavior information). At this time, for example, the learning model may be estimated based on the teacher measurement data, and the learning model may be personalized by performing additional learning based on the results recorded by the user. As a result, when biometric data is generated by the control unit 150, by associating the tag information with the biometric data, it becomes possible to generate biometric data with higher accuracy, and the biometric data itself is also used as action information. becomes possible.

Further, for example, the data management unit 131 can manage data based on tag information, such as rearranging (sorting) the data D1 in chronological order of the tags T1, and extracting only predetermined physical information and behavior information.

The biometric data generation unit 132 performs a predetermined operation on the measurement data stored in the measurement data DB 121 to generate biometric data. This biological data may be any information as long as it can be calculated from the measurement data. For example, the user's blood sugar level information, blood pressure information, heartbeat information, Electrocardiogram information, respiratory rate, body temperature information, step count information, stride information, center of gravity position information, posture information, stress information, exercise amount information, exercise load information, movement distance information, movement speed information, activity amount information, hands or legs, etc. , which is data such as motion information of the attachment site, and is calculated from measurement data by a known method. Biometric data generated by the calculation is stored in the biometric data DB 122 .

Further, by a known learning device, for example, measured data, biological data generated based on the measured data (such as heartbeat information and blood pressure information) and positive biological data (such as heartbeat information based on known medical equipment) , blood pressure information, etc.), and a learning model is created in advance based on the teacher data associated by the correspondence relationship (for example, information indicating the degree and range of error may be included), and the biometric data generation unit 132 Alternatively, determination using the learning model may be used as the above-described predetermined calculation (analysis) to generate biometric data.

The notification generating unit 133, for example, instructs the user to increase the blood sugar level based on the blood sugar level information generated from the measurement data received at predetermined periodic timing by the measuring device 300 that the user wears on a daily basis. Generate prompt notifications. The generation of notifications here includes determining which notifications are to be output data. including determining from Details will be described later.

Here, conventionally, for example, after administration of insulin, the user's blood sugar level drops, but when the user finds themselves in a dizzy state when the blood sugar level drops excessively. Taking actions to increase blood sugar levels, such as replenishing sugar to However, in this case, the blood sugar level of the user is once inadequate, and the user needs to be aware of this state. Even if the blood glucose level becomes insufficient once, even if sugar is taken, the condition does not recover immediately, and the user continues to be in an uncomfortable condition. This is true not only after administration of insulin, but also in any situation in which the blood sugar level plummets.

Therefore, in the present embodiment, the blood sugar level of the user is increased based on the blood sugar level information generated from the measurement data received at predetermined periodic timing by the measuring device 300 that the user wears on a daily basis. Generate a notification prompting you to As a more specific example, for example, preset reference blood sugar level information is compared with blood sugar level information generated at a predetermined timing, and based on the comparison result, it is determined that the blood sugar level is not sufficient for the user. If so, generate a notification prompting the user to raise their blood glucose level and send the notification to the user's user terminal 200 and/or the user's associated user terminal 200 . The person associated with the user is, for example, associated with the user information and has identification information such as account information stored in the user information DB 124 or the like. It may be a relative such as a partner, a caregiver, an assistant, etc. The reference blood sugar level information is, for example, stored in advance various blood sugar level trend information (or known blood sugar level trend information) obtained by prior experiments, etc., and contains at least age, sex, height, and weight. Based on user information including either, a value that indicates that the blood sugar level is insufficient or a value close thereto may be set, or physical condition information recorded by the user (for example, feeling unwell, feeling unwell, etc. physical condition information) and blood glucose level information associated with the physical condition information may be stored and estimated based on past blood glucose level information including the blood glucose level (e.g. mean, maximum, median, etc.). Further, in the reference blood sugar level, by setting the reference value in a plurality of steps, the user can recognize step by step whether the blood sugar level is approaching an insufficient state.

The notification urging the user to raise the blood sugar level is text information describing content urging the user to raise the blood sugar level (for example, content urging eating (including snacks), that is, content urging intake of sugar). Any information can be used as long as it is possible to recognize that it is necessary to raise the blood sugar level, such as text that encourages snacking, especially candy, but for example, which reference value is below (or not below), or to which group the reference blood sugar level information belongs to among groupings set as boundaries (for example, normal group, preliminary group, required group). attention group, etc.).

The data output unit 134 outputs biometric data and predetermined notification information to the user terminal device 200 . In the user terminal device 200, the output data may be displayed on the screen via a dedicated application, for example, so that the user can easily check it. Further, when a plurality of groups are provided by setting a plurality of reference blood sugar level information as described above, the user is prompted to increase the blood sugar level when the group falls under the predetermined reference blood sugar level information. A notification may be sent, or the content of the notification may be changed depending on which reference value information is exceeded (for example, the lower the exceeded reference value, the more the display of notation, color, characters, etc.) highlighted notification, etc.).

The input/output unit 140 is an information input device such as a keyboard and a mouse, and an output device such as a display.

The registered user information is stored in the user information DB 124 by the data management unit 131 . The processing of step S101 may be performed as preprocessing for the user to use the measuring device 300, or may be performed when the user uses the measuring device 300 for the first time.

As the process of step S102, when the user uses the measuring device 300, the measured data is transmitted from the measuring device 300 to the management server 100 via the user terminal device 200 and received via the communication unit 110 at predetermined intervals. The data management unit 131 stores the measurement data in the measurement data DB 121 of the storage unit 120 in association with the user information.
