Description

The present invention relates to an information transmission system that displays biometric information of a user of a communication terminal.

Patent document 1 and other publications propose a biometric information processing device that displays biometric information.

JP 2017-205147 A

However, notifying other users of biometric information has not been sufficiently considered.

Therefore, an object of the present invention is to provide an information transmission system for receiving notifications of other users' biometric information, etc.

An information transmission system according to the present invention includes a first communication terminal, a second communication terminal, and an information server that communicates with the first communication terminal and the second communication terminal.
The second communication terminal has a biometric information acquisition unit that acquires biometric information of a user of the second communication terminal.
The information server records a biometric information database having biometric information of a user of the second communication terminal and information regarding normal ranges of the biometric information.
A first message containing predetermined information is sent from the information server to the second communication terminal.
When there is no response from the second communication terminal to the information server during the time from the transmission of the first message until the first waiting time has elapsed, a second message including predetermined information is transmitted from the information server to the second communication terminal.
The first communication terminal receives notification of at least one of biometric information of a user of the second communication terminal and information regarding whether the biometric information includes anything outside the normal range, and at least one of information regarding whether or not there is a response from the second communication terminal to the information server.

If no response is received from the second communication terminal even after an automatic message is sent by the information server, the first communication terminal is notified. In other words, the first communication terminal is notified of the biometric information of another user (the user of the second communication terminal). Before this notification, an automatic message is sent and the biometric information is checked for abnormalities. This makes it possible to reduce unnecessary notifications.

Preferably, the first message and the second message are generated by either the first communication terminal or the information server at predetermined time intervals.
The first message includes a message indicating that the first message was automatically sent by either the first communication terminal or the information server, and includes predetermined information.
The second message includes a notification that the second message is an automatic retransmission by either the first communication terminal or the information server, and includes predetermined information.

In addition, preferably, among messages input at the first communication terminal, one including predetermined information is the first message.
The information server determines whether or not a message input to the first communication terminal and transmitted from the first communication terminal to the second communication terminal via the information server corresponds to the first message.
The second message is generated by either the first communication terminal or the information server.
The second message includes a notification that the second message is an automatic retransmission by either the first communication terminal or the information server, and includes predetermined information.
If a time period during which the moving speed of the second communication terminal is greater than or equal to a speed threshold is included before the first standby time has elapsed, no notification is made to the first communication terminal.

More preferably, if there is no response from the second communication terminal to the information server within the second waiting time after the second message is sent, a third message including specified information is sent from the information server to the second communication terminal.
The third message is generated by either the first communication terminal or the information server.
The third message includes a notice indicating that the message is an automatic re-resend message from either the first communication terminal or the information server, and includes predetermined information.
When the second communication terminal receives the second message, it outputs a reception notification sound for a longer period of time and/or at a louder volume than when the second communication terminal receives the first message.
When the second communication terminal receives the third message, it outputs a reception notification sound for a longer period of time and/or at a louder volume than when the second communication terminal receives the second message.
If there is no response from the second communication terminal to the information server during the time from when the second message is sent until the second waiting time has elapsed and the biometric information includes information outside the normal range, the first communication terminal receives notification of at least one of the biometric information of the user of the second communication terminal and information regarding whether the biometric information includes information outside the normal range.
If there is no response from the second communication terminal to the information server during the period from the transmission of the third message until the third waiting time has elapsed, the first communication terminal is notified of information regarding the presence or absence of a response from the second communication terminal to the information server for at least one of the first message, the second message, and the third message.

Also preferably, the information server records a location information database having location information of the second communication terminal.
Based on the location information database and the biometric information database, the first communication terminal displays the location information of the second communication terminal, and at least one of the biometric information of a user of the second communication terminal and information regarding whether the biometric information includes anything outside the normal range.

By displaying the first screen, it becomes possible to output biometric information, etc. along with location information of a user of a communication terminal other than the communication terminal displaying the first screen.

More preferably, the first communication terminal displays a first screen including location information of the second communication terminal and information regarding whether the biometric information of the user of the second communication terminal is outside the normal range.

It becomes possible to inform on the first screen whether the biometric information of a user of a communication terminal other than the communication terminal displaying the first screen is within the normal range, i.e., whether there is an abnormality in the biometric information.

More preferably, the first communication terminal displays a second screen showing the biometric information of the user of the second communication terminal in chronological order.

By displaying the second screen on the communication terminal, it becomes possible to check, in chronological order, the biometric information of a user of a communication terminal other than the communication terminal displaying the second screen.
This makes it possible to visually recognize time-series changes in the biometric information of a user of a communication terminal other than the communication terminal displaying the second screen.

More preferably, the first communication terminal displays a third screen having a call instruction area to the telephone number of the user of the second communication terminal, a call instruction area to the telephone number of a related person of the user of the second communication terminal, and a call instruction area to the telephone number of a specified institution.

While viewing information (first screen or second screen) displayed on the communication terminal, the user of the communication terminal can display the third screen when he/she is concerned about the state of a user of a communication terminal other than the communication terminal displaying the first or second screen.
The third screen displays a selection of instructions to call multiple contacts.
This allows you to instantly call these contacts.

More preferably, the third screen has a call instruction area for the telephone number of a specified institution, the call instruction area being a call instruction area for the telephone number of at least one of a fire station and a police station identified based on the location information of the second communication terminal.

By operating the call instruction area for the telephone number of a specified institution, it is possible to make a call to a fire station or police station close to the location information of the user of a communication terminal other than the communication terminal displaying the third screen.

Also, preferably, the second screen has an activity status display area which shows, in chronological order, information regarding whether the user of the second communication terminal is active or not and information regarding whether the user of the second communication terminal is moving or not.
When the second communication terminal is being operated or the acceleration of the second communication terminal is greater than or equal to an acceleration threshold, it is determined that the user of the second communication terminal is active.
When the moving speed of the second communication terminal is greater than or equal to a speed threshold, it is determined that the user of the second communication terminal is moving.

Preferably, the second screen has at least one of a body temperature display area showing information on the body temperature and normal body temperature range of the user of the second communication terminal in chronological order, a pulse information display area showing information on the pulse and normal pulse range of the user of the second communication terminal in chronological order, and a blood pressure information display area showing information on the blood pressure and normal blood pressure range of the user of the second communication terminal in chronological order.

Also, preferably, the information server varies the normal range of the biometric information based on external information.

This makes it possible to accurately determine whether there are any abnormalities in biometric information in response to changes in the external environment.

Preferably, the level of detail of the location information of the second communication terminal shown on the first screen is determined based on information regarding whether or not the biometric information of the user of the second communication terminal includes information outside the normal range.

In the event of an abnormality, it will be possible to display on the first screen the location information of a user of a communication terminal other than the communication terminal displaying the first screen.

A biometric information program according to the present invention is a biometric information program executed by an information server that communicates with a first communication terminal and a second communication terminal.
The second communication terminal has a biometric information acquisition unit that acquires biometric information of a user of the second communication terminal.
The information server records a biometric information database having biometric information of a user of the second communication terminal and information regarding normal ranges of the biometric information.
The biometric information program includes a first message sending step of sending a first message including specified information to a second communication terminal; a second message sending step of sending a second message including the specified information to the second communication terminal if there is no response from the second communication terminal to the information server between the sending of the first message and the elapse of a first waiting time; and a notification step of notifying the first communication terminal of at least one of biometric information of a user of the second communication terminal and information regarding whether or not the biometric information includes anything outside the normal range, and information regarding whether or not there is a response from the second communication terminal to the information server.

Preferably, the biometric information program includes a third message transmitting step of transmitting a third message including predetermined information to the second communication terminal when there is no response from the second communication terminal to the information server during the period from the transmission of the second message until the lapse of a second waiting time; a first notification step of notifying the first communication terminal of at least one of the biometric information of the user of the second communication terminal and information regarding whether the biometric information includes anything outside the normal range, as one of the notification steps, when there is no response from the second communication terminal to the information server during the period from the transmission of the first message until the lapse of the first waiting time and the biometric information includes anything outside the normal range; and a second notification step, as one of the notification steps, of notifying the first communication terminal of at least one of the biometric information of a user of the second communication terminal and information relating to whether or not the biometric information includes anything outside the normal range when there is no response from the second communication terminal to the information server within a third waiting time after the third message is transmitted, of notifying the first communication terminal of information relating to whether or not there is a response from the second communication terminal to at least one of the first message, the second message, and the third message when there is no response from the second communication terminal to the information server within a third waiting time after the third message is transmitted.
The second message includes a notification that the second message is an automatic retransmission by either the first communication terminal or the information server, and includes predetermined information.
The third message includes a notice indicating that the message is an automatic re-resend message from either the first communication terminal or the information server, and includes predetermined information.

The first embodiment will be described below with reference to the drawings. An information transmission system 1 in the first embodiment includes an information source transmission unit 20, an information server 30 (a server communication unit 31, a server recording unit 33, a server control unit 35), and communication terminals (a 51st communication terminal M51 to a 55th communication terminal M55) (see FIG. 1).
In the first embodiment, a configuration will be described in which five communication terminals are used to mutually notify each other of location information, safety information, and biological information, but the number of communication terminals is not limited to five.

(Configuration of communication terminal)
Each of the communication terminals (51st communication terminal M51 to 55th communication terminal M55) has a communication unit 11, a display unit 12, a recording unit 13, a control unit 15, and a biometric information acquisition unit 16. Note that the communication terminal is preferably a portable terminal such as a mobile phone, but may be a device fixed to a predetermined position.

(Communication unit 11)
The communication unit 11 communicates with a server communication unit 31 and with a base station that establishes a wireless link with the communication terminal.
In particular, when the first call instruction area 302a or the like is clicked on the third screen P3, a call is made to a specified telephone number.

(Display unit 12, recording unit 13, control unit 15)
The display unit 12 displays a first screen P1 (see FIGS. 7 and 8), a second screen P2 (see FIG. 9), a third screen P3 (see FIG. 10), and a fourth screen P4 (see FIG. 11).
The recording unit 13 has the biometric information program (information transmission program) in the first embodiment installed therein.
The control unit 15 executes a biometric information program and controls each unit of the communication terminal (the communication unit 11, the display unit 12, the recording unit 13, and the biometric information acquisition unit 16).

(Biometric information acquisition unit 16)
The biometric information acquiring unit 16 acquires biometric information of the user of the communication terminal.
The biological information includes at least one of the body temperature, pulse, blood pressure, and information regarding the activity state of the user of the communication terminal (information regarding whether the user of the communication terminal is active or not).
In the first embodiment, the biometric information acquisition unit 16 has a measurement unit 16a that acquires information regarding the body temperature, pulse, and blood pressure of the user of the communication terminal, and a detection unit 16b that acquires information regarding the activity state of the user of the communication terminal.
The measuring unit 16a includes a body temperature sensor, a pulse sensor, and a blood pressure sensor.

The detector 16b detects the operation state of the communication terminal.
Furthermore, the detection unit 16b has a positioning device such as a GPS and an acceleration sensor, and detects the position information and acceleration of the communication terminal.
When the communication terminal is being operated or the acceleration of the communication terminal is greater than or equal to the acceleration threshold value, the detection unit 16b determines that the user of the communication terminal is active.
When the communication terminal is not being operated and the acceleration of the communication terminal is smaller than the acceleration threshold, the detection unit 16b determines that the user of the communication terminal is inactive.
Also, when the change in location information per unit time is large, that is, when the moving speed of the communication terminal is greater than or equal to a speed threshold (for example, 30 km per hour), it is determined that the user of the communication terminal is moving.

The biological information acquisition unit 16 may be in a form built into the communication terminal, or may be a wearable type, such as a wristwatch type, that is attached to the user of the communication terminal.
For example, the measuring unit 16a may be configured as a wearable type, and the detecting unit 16b may be built into the communication terminal.
In this case, the measurement unit 16a communicates with the communication terminal via short-range wireless communication or the like.
Some of the functions of the detection unit 16b, such as detection of the operation state of the communication terminal, may be executed by the control unit 15 as the detection unit 16b.
Furthermore, the biometric information acquisition unit 16 may identify the user and calculate the biometric information (such as body temperature) of the user from the image information obtained by the imaging device.

It is desirable for the biometric information acquisition unit 16 to acquire the biometric information at all times.
However, information on body temperature, blood pressure, and the like may be obtained at regular intervals (for example, a first time T1, which will be described later).
The biological information obtained by the biological information acquisition unit 16 is transmitted to the information server 30 via the communication unit 11 .

(Biometrics Program)
In the first embodiment, an example is shown in which a user with user ID: 11 (user name: Papa, Taro) logs in to the biometric information program (information transmission program) installed on the 51st communication terminal M51 with user ID: 11, a user with user ID: 12 (user name: Hanako) logs in to the biometric information program installed on the 52nd communication terminal M52 with user ID: 12, a user with user ID: 13 (user name: Susumu) logs in to the biometric information program installed on the 52nd communication terminal M53 with user ID: 13, a user with user ID: 23 (user name: Grandpa) logs in to the biometric information program installed on the 54th communication terminal M54 with user ID: 23, and a user with user ID: 24 (user name: Grandma) logs in to the biometric information program installed on the 55th communication terminal M55 with user ID: 24.
In addition, the screen display examples of Figures 7 to 11 are displayed after a user with user ID: 11 (user name: Papa, Taro) logs in to the biometric information program installed in the 51st communication terminal M51 with user ID: 11.

Further, the "first communication terminal" and "communication terminal" described in the claims will be described as corresponding to the 51st communication terminal M51, but are not limited to the 51st communication terminal M51.
Further, the "second communication terminal" described in the claims will be explained as corresponding to the 54th communication terminal M54, but is not limited to the 54th communication terminal M54.

Information transmission and reception between the information server 30 and the communication terminal is performed via a biometric information program.
In the first embodiment, a configuration is described in which a biometric information program installed in each communication terminal is used. However, as shown in the third embodiment , a configuration may also be used in which each communication terminal accesses a server of an ASP (Application Service Provider) via a network and uses the biometric information program stored in the server of the ASP.

(Information source sending unit 20)
The information source transmission unit 20 outputs disaster information (hazard information) to a server communication unit 31 of the information server 30 .
The disaster information includes at least information regarding the location of the disaster, and in the first embodiment, includes information regarding the type, location, and date and time of the disaster.
In the first embodiment, the disaster information is described as disaster information related to an earthquake, but it may be information about other disasters such as floods. Furthermore, the disaster information may be not only information about past occurrences such as earthquake occurrence reports, but also information about future occurrences predicted such as lightning warnings and earthquake predictions.
Furthermore, the danger information output by the information source transmission unit 20 to the server communication unit 31 of the information server 30 is not limited to disaster information and may be other danger information. For example, information on suspicious persons, accident information, and incident information such as murder and injury cases are considered as the danger information. The danger information includes information on the location corresponding to the suspicious person information.

The information source transmitting unit 20 is installed in a location such as the Meteorological Agency where disaster information can be transmitted, in a state where network connection with the information server 30 is possible.
However, the information source transmission unit 20 may not be installed, and a user who receives disaster-related information may input the disaster information to the information server 30 via an input/output terminal 70, and based on this, the information server 30 may transmit the disaster information to the communication terminal.

In the first embodiment, the information server 30 receives disaster information from the information source transmission unit 20, which has the following information: "Disaster type: Earthquake (maximum predicted seismic intensity of 6- and magnitude 7.1 in the Shikoku region), location: Shikoku region, date and time: 8:30 a.m. on August 3, 2016," and the 51st communication terminal M51 to the 55th communication terminal 55 each transmit their own location information, etc. to the information server 30 under the conditions shown below.

The 51st communication terminal M51 transmitted the location information and safety response information acquired at 8:50 on August 3, 2016 to the information server 30.
The 52nd communication terminal M52 transmitted the location information and safety response information acquired at 8:46 on Aug. 3, 2016 to the information server 30.
The 53rd communication terminal M53 transmitted the location information and safety response information acquired at 8:45 a.m. on Aug. 3, 2016 to the information server 30.
The 54th communication terminal M54 transmitted the location information acquired at 8:12 on Aug. 3, 2016 to the information server 30, but did not transmit safety response information to the information server 30.
The 55th communication terminal M55 transmitted the location information acquired at 8:27 on Aug. 3, 2016 to the information server 30, but did not transmit safety response information to the information server 30.

(Information Server 30)
Next, each unit of the information server 30 (server communication unit 31, server record unit 33, server control unit 35) will be described.

(Server communication unit 31 of information server 30)
The server communication unit 31 of the information server 30 communicates with each of the communication terminals (the 51st communication terminal M51 to the 55th communication terminal M55) registered in the location information database D1, and acquires the location information of each communication terminal and the biometric information of the user of each communication terminal every first time T1 (e.g., 30 minutes) before transmitting disaster information to these communication terminals.

For example, a configuration may be considered in which each communication terminal uses a biometric information program installed in each communication terminal to transmit location information and biometric information of the user of each communication terminal to the server communication unit 31 of the information server 30 every first time T1.

In addition, instead of obtaining location information from each communication terminal, it is possible for the server communication unit 31 of the information server 30 to communicate with any of the following in the communication carrier: a base station which forms a wireless link with the communication terminal; a mobile switching center (MSC) which performs routing (selection of communication routes) for the communication terminal, call setup/disconnection, billing, etc.; a visitor location register (VLR) which is a location registration database for each area covered by the mobile switching center; a gateway switching center (GMSC), or a home location register (HLR) which is a database that manages user information such as mobile phone numbers, identification information for the communication terminal (terminal identification numbers such as IMEI, SIM card identification numbers such as ICCID), and location information, to obtain location information for each communication terminal.

When acquiring location information of each communication terminal, there is no restriction on the level of detail of the location information, and the most detailed level of location information that can be acquired is acquired and recorded in the location information database D1.
However, when disclosing location information of a communication terminal (first communication terminal) or another communication terminal (second communication terminal), the level of detail of the location information is adjusted based on the "level of detail of the location information to be disclosed (first level of detail parameter dp1, second level of detail parameter dp2)" set by the user of the communication terminal.

In addition, the server communication unit 31 of the information server 30 receives disaster information from the information source transmission unit 20, and after receiving the disaster information (or after the disaster information is input by the input/output terminal 70), transmits the disaster information, etc. to the communication terminals (51st communication terminal M51 to 55th communication terminal M55) based on the location information database D1 and the group information database D3, and receives safety response information from the communication terminals.

(Server Recording Unit 33 of Information Server 30)
The server recording unit 33 of the information server 30 records a location information database D1, a biometric information database D2, a group information database D3, an organization information database D4, and a contact information database D5.
In addition, the server recording unit 33 has installed therein a program that communicates with the communication terminal and transmits and receives disaster information, biometric information, and the like, in response to the biometric information program (information transmission program) installed in the communication terminal.

(Location information database D1)
The location information database D1 indicates the relationship between information on users of communication terminals, the communication terminals (communication terminal names), information on the locations of the communication terminals, and information on safety transmitted from the communication terminals (see FIG. 2).
The information relating to users of the communication terminals in the location information database D1 is information input by the users via each communication terminal (information set by the user setting operation), and includes the user name, user ID (identification number for logging in to the biometric information program), and user mark (which can be a photograph) corresponding to each communication terminal.
The user names may be in a form in which different names are used for each group, such as user names: Papa, Taro corresponding to user ID: 11.

Information regarding the location of the communication terminal is information received from an HLR or the like or from the communication terminal, and includes latitude and longitude information corresponding to each communication terminal, the area name corresponding to the latitude and longitude information, and the positioning date and time.

The latitude and longitude information and positioning date and time in the location information database D1 are obtained every first time T1 by the server communication unit 31 of the information server 30 communicating with the communication terminals (the 51st communication terminal M51 to the 55th communication terminal M55) registered in the location information database D1, or by the server communication unit 31 communicating with a base station or the like in a communication carrier.

The area names corresponding to the latitude and longitude information in the location information database D1 are obtained by converting the latitude and longitude information of the communication terminal into area names using a table (not shown) that converts latitude and longitude information into area names.

The information regarding safety in the location information database D1 indicates whether or not a safety response operation has been performed from the communication terminals (51st communication terminal M51 to 55th communication terminal M55) registered in the location information database D1 by the server communication unit 31 of the information server 30, and is initialized when disaster information is sent, and the parameter in the safety type column (safety type parameter sp) is set to the initial value (sp = 1) which indicates that the safety of the users of all communication terminals is unknown (no safety response operation has been performed).

After initialization, the safety information in the location information database D1 is updated when safety response information is received from the communication terminal.

When a specific operation for responding to a safety question (safety response operation) is performed by the user of the communication terminal on the biometric information program installed in the communication terminal, the parameter value in the safety type field is changed to 0 (safety type parameter sp = 0 indicating that a response has been made). In other words, when the specific operation for responding to a safety question (safety response operation) is not performed, the initial value: 1 is maintained.

(Biometric information database D2)
The biometric information database D2 indicates the relationship between information about the user of the communication terminal, the threshold for determining abnormalities in the biometric information of the user of the communication terminal (information about the normal range), the biometric information of the user of the communication terminal, and information about the presence or absence of abnormalities in the user of the communication terminal (see Figure 3).
The information relating to the users of the communication terminals in the biometric information database D2 is information input by the users via each communication terminal (information set by the user setting operation), and includes a user name and user ID corresponding to each communication terminal.

The information relating to normal ranges in the biometric information database D2 is information input by the user via each communication terminal (information set by the user setting operation), and includes the normal range of body temperature, normal range of pulse, and normal range of blood pressure (normal range for systolic blood pressure, normal range for diastolic blood pressure) for the user corresponding to each communication terminal.
The information regarding the normal range may be set individually by each user, or may be set to a fixed value that does not vary depending on the user.

In addition, the information regarding the normal range may be set individually, may be set to a fixed value, or may be further adjusted based on external information (e.g., location information of the communication terminal, weather information, etc.).
For example, the information server 30 may communicate with an external information device 90 to obtain weather information, and if the weather information includes a prediction that the temperature in the area including the location of the user's communication terminal will be high, the upper limit of the normal range for body temperature may be adjusted to be higher, and the biometric information database D2 may be updated.
That is, the information server 30 varies the normal ranges of biological information (normal ranges of body temperature, pulse rate, and blood pressure) based on external information.
This makes it possible to accurately determine whether or not there is an abnormality in the biological information in response to changes in the external environment.

The biometric information in the biometric information database D2 is information obtained by the biometric information acquisition unit 16 of each communication terminal, and includes information regarding body temperature, pulse rate, blood pressure, and activity status (active or inactive).

The biometric information in the biometric information database D2 is obtained every first time T1 by the server communication unit 31 of the information server 30 communicating with the communication terminals (the 51st communication terminal M51 to the 55th communication terminal M55) registered in the biometric information database D2.

The information on the presence or absence of an abnormality of the user of the communication terminal in the biometric information database D2 indicates whether the biometric information of the user of the communication terminal includes anything outside the normal range.
If all of the vital signs (body temperature, pulse rate, blood pressure) are within the normal range, the parameter indicating whether or not the user is abnormal (vital sign parameter rp) is set to the initial value (rp = 0) indicating that there is no abnormality mode.
If at least one of the vital signs (body temperature, pulse rate, or blood pressure) is not within the normal range, the vital sign parameter rp is set to a value (rp=1) indicating an abnormal mode.
The determination of whether or not the abnormal mode is present may be made using only the most recent vital sign information, or may include vital sign information from the most recent vital sign information up to a second time T2 (e.g., T2 = 2 hours) in the past.

FIG. 3 shows an example of information regarding the normal range of a user with user ID: 23 (user name: Grandpa) and biometric information measured at 8:00 a.m. on August 3, 2016, and information regarding the normal range of a user with user ID: 24 (user name: Grandma) and biometric information measured at 8:00 a.m. on August 3, 2016.
The biometric information of the user with user ID: 23 (user name: Grandpa) measured at 8:00 on August 3, 2016 showed that the systolic blood pressure measurement value (132 mmHg) exceeded the normal range for systolic blood pressure (130 mmHg or less), and therefore the biometric information parameter rp was set to a value (rp = 1) indicating an abnormal mode.
For the user with user ID: 24 (user name: Grandma), all of the biometric information measured at 8:00 on August 3, 2016 was within the normal range, so the biometric information parameter rp is set to a value (rp = 0) indicating that the user is not in abnormal mode.

(Group information database D3)
The group information database D3 indicates the relationship between information about groups used in group chat (group message) in the biometric information program and information about users belonging to the groups (see FIG. 4).
The information about the group is information input by the user via the communication terminal (information set by the group setting operation), and includes the group name, group ID (group identification number), and group mark (which may be a photograph).
The information regarding users belonging to the group is information input by the user via a communication terminal (information set by the location information disclosure designation operation), and includes the name of the user belonging to the group, the user ID of the user belonging to the group, the level of detail (first level of detail parameter dp1) of the location information to be disclosed under normal circumstances (while the safety type parameter sp is 0 and the biometric information parameter rp is 0), and the level of detail (second level of detail parameter dp2) of the location information to be disclosed during a disaster (while the safety type parameter sp is 1) or in abnormal mode (while the biometric information parameter rp is 1).

In the first embodiment, a form is described in which the first level of detail parameter dp1 and the second level of detail parameter dp2 have three levels (1: discloses coarse location information (e.g., prefecture level), discloses medium level of coarse location information (e.g., city/town level), 3: discloses fine location information (e.g., street address level)), but a form having two levels or four or more levels may also be used.

It is preferable that the second detail level parameter dp2 is set to a level of detail equal to or greater than that of the first detail level parameter dp1.
For example, the first level of detail parameter dp1 may be adjustable by the user in three steps, and the second level of detail parameter dp2 may be fixed at the finest level of detail.

In the first embodiment, the group name: Tanaka family (group ID: G001) includes a user with user ID: 11 (user name: Papa, first level of detail parameter dp1: 2, second level of detail parameter dp2: 3), a user with user ID: 12 (user name: Hanako, first level of detail parameter dp1: 1, second level of detail parameter dp2: 3), and a user with user ID: 13 (user name: Susumu, first level of detail parameter dp1: 2, second level of detail parameter dp2: 3).
In addition, the group name: Parents' home (group ID: G002) includes the user with user ID: 23 (user name: Grandpa, first level of detail parameter dp1: 3, second level of detail parameter dp2: 3), the user with user ID: 24 (user name: Grandma, first level of detail parameter dp1: 3, second level of detail parameter dp2: 3), and the user with user ID: 11 (user name: Taro, first level of detail parameter dp1: 1, second level of detail parameter dp2: 3).

(Institution information database D4)
The agency information database D4 indicates the relationship between agency names (such as police, fire, etc., and telephone numbers) and information on jurisdictions for each region (see FIG. 5).
The information regarding the jurisdictional area may be detailed information that strictly corresponds to the area defined by the administrative agency, but the jurisdictional area may also be a circular area centered on approximately the center of the area and including approximately the entire area of the area.
The facility information database D4 is used when the communication terminal makes a call to the telephone number of a police station or a fire station close to the location of the communication terminal of the user corresponding to the biometric information.

(Contact Information Database D5)
The contact information database D5 indicates information regarding the user of the communication terminal, and the relationship between the user's telephone number, the telephone number and name of the user's first related person (neighbor), and the telephone number and name of the user's second related person (care manager) (see Figure 6).
The contact information database D5 is used when the communication terminal makes a call to the telephone number of the user or related persons (neighbors, care managers) corresponding to the biometric information.
The contact information database D5 may include email addresses of the user's first associates (neighbors) and the like.

(Server control unit 35 of information server 30)
The server control unit 35 of the information server 30 executes the programs installed in the server recording unit 33 , and controls the server communication unit 31 and the server recording unit 33 .

Specifically, when the information server 30 receives disaster information from the information source transmission unit 20, the server control unit 35 transmits the disaster information via the server communication unit 31 to the communication terminals (51st communication terminal M51 to 55th communication terminal M55) registered in the location information database D1.

In addition, when the information server 30 receives information about the user, information about the group to which the user belongs, or information about the level of detail of the location information to be disclosed from the 51st communication terminal M51 to the 55th communication terminal M55 through a user setting operation, a group setting operation, a location information disclosure designation operation, etc., the server control unit 35 updates the location information database D1, the biometric information database D2, the group information database D3, and the contact information database D5 recorded in the server recording unit 33.

In addition, when the information server 30 receives the location information of the 51st communication terminal M51 to the 55th communication terminal M55, the server control unit 35 updates the location information in the location information database D1 recorded in the server recording unit 33.

In addition, when the information server 30 receives safety response information from the 51st communication terminal M51 to the 55th communication terminal M55 based on the safety response operation by the user of the communication terminal, the server control unit 35 updates the safety type parameter sp in the location information database D1 recorded in the server recording unit 33.
When the 51st communication terminal M51 to the 55th communication terminal M55 transmit safety response information to the information server 30 based on the safety response operation, positioning is performed and location information is also transmitted.
Based on the transmitted location information, the location information in the location information database D1 is updated.
When the safety response information is transmitted based on the safety response operation, the location information may not be transmitted.

In addition, the server control unit 35 updates the biometric information database D2 recorded in the server recording unit 33 when the information server 30 receives information regarding the normal range from the 51st communication terminal M51 to the 55th communication terminal M55 based on the threshold setting operation by the user of the communication terminal.
Furthermore, the server control unit 35 updates the biometric information database D2 recorded in the server recording unit 33 when the information server 30 receives biometric information from the 51st communication terminal M51 to the 55th communication terminal M55.

In addition, the server control unit 35 updates the contact information database D5 recorded in the server recording unit 33 when the information server 30 receives information regarding the user's telephone number and the telephone numbers and names of related parties (neighbors and care managers) from the 51st communication terminal M51 to the 55th communication terminal M55 based on the telephone number setting operation by the user of the communication terminal.

In addition, the server control unit 35 transmits, via the server communication unit 31, to the communication terminal of the user (self) who has logged in to the biometric information program, location information, safety information, and biometric information of other users (other people) who belong to the group to which the user (self) who has logged in to the biometric information program belongs, based on the location information database D1, the biometric information database D2, and the group information database D3.
For example, a user with user ID: 11 (user name: Papa, Taro) belongs to a group with group name: Tanaka family (group ID: G001) and a group with group name: Parents' home (group ID: G002), so location information, safety information, and biometric information of users belonging to these groups (user with user ID: 12 and user ID: 13 who belong to the group with group name: Tanaka family (group ID: G001), user with user ID: 23 and user ID: 24 who belong to the group with group name: Parents' home (group ID: G002)) are transmitted to the 51st communication terminal M51 corresponding to user ID: 11.

The location information sent from the information server 30 to the communication terminal is the location information with the most detailed level, and the level of detail of the location information displayed on the display unit 12 of the communication terminal is adjusted based on the safety information (safety type parameter sp) and the biometric information (biometric information parameter rp).
Specifically, for users whose safety type parameter sp is 0 and whose biometric information parameter rp is 0, location information is displayed with the level of detail of location information disclosed under normal circumstances (first level of detail parameter dp1), and for users whose safety type parameter sp is 1 or whose biometric information parameter rp is 1, location information is displayed with the level of detail of location information disclosed in the event of a disaster (second level of detail parameter dp2).
However, at the stage of transmitting location information from the information server 30 to each communication terminal, the location information may be transmitted to each communication terminal with a different level of detail for each transmitting communication terminal and for each user to whom the location information is disclosed, based on the safety information (safety type parameter sp) and biometric information (biometric information parameter rp) recorded in the location information database D1.

(Biometrics Program)
Next, the biometric information program will be described in detail.
The biometric information program executes a receiving step of receiving location information and biometric information of other communication terminals from the information server 30, a first display step of displaying a first screen P1 (display of disaster information and location information for each user) on the display unit 12 of the communication terminal in which the biometric information program is installed, a second display step of displaying a second screen P2 (display of a list of biometric information) on the display unit 12 of the communication terminal in which the biometric information program is installed, a third display step of displaying a third screen P3 (display of a list of telephone contacts) on the display unit 12 of the communication terminal in which the biometric information program is installed, a calling step of making a call to a contact specified on the third screen P3, and a fourth display step of displaying a fourth screen P4 (display of a message) on the display unit 12 of the communication terminal in which the biometric information program is installed.

Either the first screen P1 to the fourth screen P4 is displayed on the display unit 12 of the communication terminal by operation of the user.

(First screen P1)
The first screen P1 has a disaster information display area 101, a user position information display area 103, and a screen switching button display area 105 (see FIGS. 7 and 8).

The disaster information display area 101 displays information (area, date and time, maximum seismic intensity, magnitude) about the earthquake that occurred just before, and displays a map in the background centered on the area included in the information about the earthquake.
In the disaster information display area 101, for the first disaster information and the second disaster information, a disaster level mark ma1 indicating the scale of the disaster (the numerical value of the maximum predicted seismic intensity) is provided.
In the first embodiment, the disaster level mark ma1 is displayed in outline characters.

In the first embodiment, the disaster level mark ma1 is shown surrounded by a substantially rectangular frame, but the frame may be omitted and only a numerical value indicating the scale of the disaster may be displayed in the disaster information display area 101.

If no earthquakes have occurred within a certain period of time in the past, the disaster information display area 101 will display the message "No earthquakes have occurred" along with detailed location information of the communication terminal.
Note that the disaster information display area 101 may simply display "No earthquake has occurred," without displaying detailed location information of the communication terminal.

In the user position information display area 103, for each group to which the user of the communication terminal belongs, there are provided a group mark, group name, user mark relating to the user, user name, position information, and the date and time when the position information was obtained.
Figures 7 and 8 show an example in which location information and the like of users belonging to each of two groups (first group name: Tanaka family, group ID: G001, second group name: Parents' home, group ID: G002) to which a user with user ID: 11 belongs is displayed.

If only the user of the communication terminal is set in the group and no users of other communication terminals are set, only information about the user of the communication terminal (user mark, user name, location information, date and time when the location information was acquired) is displayed. In this case, information about the group (group mark, group name, etc.) may be omitted.

When the amount of information to be displayed in the user location information display area 103 is large, it is displayed in a state in which it can be scrolled vertically. Figure 7 shows the state in which the upper area of the user location information display area 103 is displayed, and Figure 8 shows the state in which the lower area of the user location information display area 103 is displayed.

The level of detail of the location information displayed in the user location information display area 103 is determined based on the safety information (safety type parameter sp) in the location information database D1, the biometric information (biometric information parameter rp) in the biometric information database D2, and the level of detail of the disclosed location information in the group information database D3 (first level of detail parameter dp1, second level of detail parameter dp2).
For a user whose safety type parameter sp is 0 and whose biometric information parameter rp is 0, i.e., a user who has received a safety response and has no abnormalities detected in their biometric information, the user's location information is displayed with the level of detail of the location information disclosed under normal circumstances, based on the first level of detail parameter dp1.
7 and 8 show an example in which the safety type parameter sp of a user named Hanako who belongs to a group named Tanaka family is 0, the biometric information parameter rp is 0, and the location information is displayed with the level of detail of the location information disclosed under normal circumstances (first level of detail parameter dp1:1 (coarse location information level)).

Furthermore, even if the user ID is the same, the level of detail of the location information disclosed can be different for each group.
Figures 7 and 8 show an example in which a user with user ID: 11, as user name: Dad, in a group named: Tanaka family, normally displays medium location information (Minato-ku, Tokyo) based on the first level of detail parameter dp1, and in a group named: Parents' home, as user name: Taro, normally displays coarse location information (Tokyo) based on the first level of detail parameter dp1.

For a user whose safety type parameter sp1 is 1 or whose biometric information parameter rp is 1, i.e., a user who has not performed a safety response operation or whose biometric information has an abnormality detected, the user's location information is displayed with the level of detail of the location information to be disclosed in the event of a disaster, based on the second level of detail parameter dp2.
7 and 8 show an example in which the safety type parameter sp of a user name: Grandpa who belongs to a group name: Parents' home is 1, the biometric information parameter rp is 1, and the location information is displayed with the level of detail of the location information to be disclosed in the event of a disaster (second level of detail parameter dp2: 3 (fine location information level)).
FIG. 8 shows an example in which the safety type parameter sp of the user name: grandmother belonging to the group name: parent's home is 1, the biometric information parameter rp is 0, and the location information is displayed with the level of detail of the location information to be disclosed in the event of a disaster (second level of detail parameter dp2: 3 (fine location information level)).

In addition, near the user mark, user name, or location information, a safety unconfirmed mark ma2 is provided which lights up when either the safety type parameter sp is 1 (no safety response has been given) or the safety type parameter sp is 0 (safety response has been given) and is turned off in the other case.
In the first embodiment, a mark (a diamond with an exclamation mark inside) is provided to the upper right of the user mark as the unconfirmed safety mark ma2, which lights up when the safety type parameter is 1 (no safety response has been given) and turns off when the safety type parameter is 0 (a safety response has been given).
However, the shape of the safety unconfirmed mark ma2 is not limited to this, and may be another shape, such as a circular frame surrounding the user mark.

In addition, a biometric abnormality mark ma3 is provided near either the user mark, the user name, or the location information, which lights up when either the biometric information parameter rp is 1 (an abnormality has been detected in the biometric information) or the biometric information parameter rp is 0 (no abnormality has been detected in the biometric information) and is turned off in the other case.
That is, the communication terminal displays the first screen P1 including information (biometric abnormality mark ma3) regarding whether or not the biometric information of the user of the other communication terminal includes anything outside the normal range.
In the first embodiment, a mark (the word “abnormal” and a rectangular frame around the character) is provided diagonally above and to the right of the position information as the biometric abnormality mark ma3, which lights up when the biometric information parameter rp is 1 and turns off when the biometric information parameter rp is 0.
When the biological abnormality mark ma3 is clicked, the display is switched to the second screen P2. The second screen P2 will be described in detail later.

However, instead of including on the first screen P1 information regarding whether the biometric information of a user of another communication terminal includes anything outside the normal range, the communication terminal may include on the first screen P1 some or all of the biometric information of a user of another communication terminal.

In addition, when the biometric abnormality mark ma3 is clicked, instead of switching to the display of the second screen P2, it may be configured to switch to the display of the third screen P3 described below.

It should be noted that the switching of the display from the first screen P1 to the second screen P2 is not limited to clicking on the biological abnormality mark ma3.
For example, a conceivable form is that by clicking on an area in the user position information display area 103 in which the user's name is displayed, the display can be switched to the second screen P2 including the biometric information corresponding to the user's name.
In this case, it becomes possible to display details of the biometric information of a user who has been determined to have no abnormality in the biometric information (second screen P2) on the display unit 12 of the communication terminal.

By clicking on the area in the user location information display area 103 where the user mark is displayed, the display is switched to the fourth screen P4 including a message with the user ID corresponding to the user name (see FIG. 11). However, the display may be switched to the fourth screen P4 by another operation.

When the vicinity of the location information for each user displayed in the user location information display area 103 is clicked, the display switches to a map display (not shown) of that user's location information.

The screen switching button display area 105 has a home button 105a for switching to the display of the first screen P1, a chat button 105b for switching to a chat screen (not shown) of a group to which the user belongs, a disaster information button 105c for switching to a chronological list display of disaster information (not shown), a shelter button 105d for switching to a list display of shelters (not shown) close to the location of the communication terminal, and a settings button 105e for switching to an operation screen display (not shown) for editing the contents of the biometric information database D2, etc.

By displaying the first screen P1, it becomes possible to output biometric information, etc. along with location information of a user of a communication terminal other than the communication terminal displaying the first screen P1.

In particular, it becomes possible to inform on the first screen P1 whether or not the biometric information of a user of a communication terminal other than the communication terminal displaying the first screen P1 includes information outside the normal range, i.e., whether or not there is an abnormality in the biometric information.

Furthermore, the level of detail of the position information displayed together with the biometric information on the first screen P1 is determined according to the presence or absence of an abnormality in the biometric information.
For this reason, when there is no abnormality, detailed location information is not displayed in order to protect privacy, but when there is an abnormality, it becomes possible to display on the first screen P1 the location information of a user of a communication terminal other than the communication terminal displaying the first screen P1.

(Second screen P2)
The second screen P2 has a first name display area 201 for displaying the name of the user corresponding to the biometric information, and a biometric information display area 202 for displaying the biometric information (see FIG. 9). Note that the second screen P2 may also be provided with a screen switching button display area 105.
The biological information display area 202 includes a body temperature display area 202a, a pulse rate display area 202b, a blood pressure display area 202c, and an activity state display area 202d.

The information on body temperature, pulse rate, and blood pressure in the biological information display area 202 displays the user's biological information (normal ranges and measured values) in chronological order for each measurement type.
FIG. 9 shows the normal range as a dashed line and the measured value as a solid line.
It is desirable to display the measured value in a different output manner depending on whether the measured value is within the normal range or outside the normal range.
For example, a solid line representing a measurement value within the normal range may be displayed in black, and a solid line representing a measurement value outside the normal range may be displayed in red.
FIG. 9 shows an example in which measurements that are within the normal range are displayed as thin lines, and measurements that are outside the normal range are displayed as thick lines.

The body temperature display area 202a displays information about the user's body temperature in chronological order.
The pulse display area 202b displays information about the user's pulse in chronological order.
The blood pressure display area 202c displays information about the user's blood pressure in chronological order.

The information on the activity state in the biological information display area 202 is displayed in chronological order in the biological information display area 202, showing active time periods, inactive time periods, and moving time periods.
FIG. 9 shows active periods as white bands, inactive periods as black bands, and periods of movement as shaded bands.

By displaying the second screen P2 on the display unit 12 of the communication terminal, it becomes possible to check, in chronological order, the biometric information of a user of a communication terminal other than the communication terminal displaying the second screen P2.
This makes it possible to visually confirm the time-series changes in the biometric information of a user of a communication terminal other than the communication terminal displaying the second screen P2.

When a specific operation for switching to the third screen P3 (for example, an operation of sliding to the right) is performed while the second screen P2 is displayed, the display is switched to the third screen P3.
When a specific operation (for example, an operation of sliding leftward) is performed to switch to the first screen P1 while the second screen P2 is displayed, the display is switched to the first screen P1.
In the case where the screen switching button display area 105 is provided on the second screen P2, the display can be switched to the first screen P1 by clicking the home button 105a.

(Safety Confirmation Control of the Second Embodiment)
In the first embodiment, an example was described in which when a specific operation (e.g., sliding to the right) is performed to switch to the third screen P3 while the second screen P2 is displayed, the display is switched to the third screen P3, i.e., the biometric information program executes the third display step.
However, in cases where there is no reply to a message including a specific character string sent using the fourth screen P4, the screen may be switched to the third screen P3 (see the second embodiment, FIGS. 12 to 14).
In addition to switching to the third screen P3, further operations such as calling a telephone number corresponding to the first call instruction area 302a, sending a notification to a specified communication terminal (sending a specified message) may also be performed.

Here, as an example, we will explain the screen switching operation control when a first message including a specified string (specified information) is sent from the 51st communication terminal M51 of a user with user ID: 11 (user name: Papa, Taro) to the 54th communication terminal M54 of a user with user ID: 23 (user name: Grandpa).

When a message is sent using the fourth screen P4, the control unit 15 of the 51st communication terminal M51 that sent the message determines whether the message contains a specified character string related to safety confirmation, such as "Are you OK?", i.e., whether the message corresponds to the first message (see step S11 in FIG. 12).
The specified character string may be included in the biometric information program and recorded in the recording unit 13 at the time of installation, or the specified character string may be set by the user of the communication terminal and recorded in the recording unit 13.
In addition, if the message contains a specified character string, the control unit 15 of the 51st communication terminal M51 determines whether or not there is a response from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) within the first waiting time TT1 (e.g., TT1 = 20 minutes) from when the message (first message) is sent (see steps S12 and S13 in Figure 12).

The response from the 54th communication terminal M54 here is defined as the receipt of a reply to a message from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) to the 51st communication terminal M51 of the user with user ID: 11 (user name: Papa, Taro) via the information server 30.
However, the response from the 54th communication terminal M54 may be defined as the activation of the biometric information program in the 54th communication terminal M54, and the state in which the first message from the 51st communication terminal M51 of the user with user ID: 11 (user name: Papa, Taro) can be displayed (the message has been read). In this case, information indicating that the message has been read is transmitted (notified) to the 51st communication terminal M51 via the information server 30.
Furthermore, a response from the 54th communication terminal M54 may be defined as a predetermined operation (for example, a swipe operation) performed by a user on the 54th communication terminal M54. In this case, information that the predetermined operation has been performed is transmitted (notified) to the 51st communication terminal M51 via the information server 30.

However, based on information regarding the activity status of the user with user ID: 23 (user name: Grandpa), if the time period is during which the user is on the move, there is a high possibility that the user with user ID: 23 (user name: Grandpa) is safe and active, so even if there is no response, the screen switching operation control may be terminated.
In other words, if a time period during which the moving speed of the 54th communication terminal M54 is greater than or equal to a speed threshold is included between the transmission of the first message and the lapse of the first waiting time TT1, the 51st communication terminal M51 is not notified of information regarding the presence or absence of a response from the 54th communication terminal M54 to the information server 30.

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 1 (an abnormality in the biometric information is detected), the control unit 15 of the 51st communication terminal M51 switches from displaying the fourth screen P4 to displaying the third screen P3 (see steps S14 and S21 in Figure 12).

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 0 (no abnormality in the biometric information is detected), the control unit 15 of the 51st communication terminal M51 sends a second message to the 54th communication terminal M54 via the information server 30 (see steps S14 and S15 in Figure 12).
In this case, it is preferable that the second message includes information indicating that the message is to be automatically resent by the biometric information program, such as "automatic resend 1."
In addition, it is desirable for the sound output device (audio equipment, amplifier, speaker, etc.) of the 54th communication terminal M54 to output a receipt notification sound for a longer period of time and/or at a louder volume when the second message is received than when the first message is received.

The control unit 15 of the 51st communication terminal M51 determines whether or not there is a response from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) within the second waiting time TT2 (e.g., TT2 = 30 minutes) after the second message is sent (see steps S16 and S17 in Figure 12).
If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 1 (an abnormality in the biometric information is detected), the control unit 15 of the 51st communication terminal M51 switches from displaying the fourth screen P4 to displaying the third screen P3 (see steps S18 and S21 in Figure 12).

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 0 (no abnormality in the biometric information is detected), the control unit 15 of the 51st communication terminal M51 sends a third message to the 54th communication terminal M54 via the information server 30 (see steps S18 and S19 in Figure 12).
In this case, it is preferable that the third message includes information indicating that the message is being automatically resent by the biometric information program, such as "automatic resend 2."
It is also preferable that the sound output device of the 54th communication terminal M54 outputs the reception notification sound for a longer period of time and/or at a louder volume when the third message is received than when the second message is received.

The control unit 15 of the 51st communication terminal M51 determines whether or not there is a response from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) within the third waiting time TT3 (e.g., TT3 = 40 minutes) after the third message is sent (see step S20 in Figure 12).
When there is no response from the 54th communication terminal M54, the control unit 15 of the 51st communication terminal M51 switches the display from the fourth screen P4 to the third screen P3 (see step S21 in FIG. 12).

Figure 13 shows an example in which the text messages "Are you OK? (first message)", "Automatic retransmission 1: Are you OK? (second message)", and "Automatic retransmission 2: Are you OK? (third message)" are sent from the information server 30 to the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa), and these messages are displayed in the first message content display area 403b.
The screen display example in Figure 13 is displayed after a user with user ID: 11 (user name: Papa, Taro) logs in to the biometric information program installed on the 51st communication terminal M51 with user ID: 11.

When no response is received even after sending a first message generated manually by the user and sending a second message automatically by the communication terminal, the third screen P3 can be displayed.
The third screen P3 displays a selection of instructions to call multiple contacts.
This allows you to instantly call these contacts.

Thereafter, the control unit 15 of the 51st communication terminal M51 may make a call to a telephone number corresponding to any one of the first call instruction area 302a to the seventh call instruction area 302g.
In addition, the control unit 15 of the 51st communication terminal M51 may send a predetermined message to the telephone number by SMS.
The specified message includes at least one of the following: a message that no response has been received from the user of the 54th communication terminal M54; and a message that an abnormality has been detected in the biometric information of the user of the 54th communication terminal M54 (see FIG. 14).

Figure 14 shows an example in which a specified message including information indicating that no response has been received from the user of the 54th communication terminal M54 and that no abnormality has been detected in the biometric information of the user of the 54th communication terminal M54 is sent from the 51st communication terminal M51 to a terminal (such as a telephone) of a neighbor (Mr. Suzuki) of the user of the 54th communication terminal M54.
In addition, the specified message may include information showing the biometric information of the user of the 54th communication terminal M54 in chronological order, as shown on the second screen P2.
Furthermore, if an email address is set in the contact information database D5 or the like, the control unit 15 of the 51st communication terminal M51 may send the specified message to the set email address.

In other words, the communication terminal that receives the specified message (such as a communication terminal of the neighbor (Mr. Suzuki) of the user of the 54th communication terminal M54) receives notification of at least one of information regarding whether or not there is a response from the 54th communication terminal M54 to the information server 30, and information regarding the normal range of the biometric information of the user of the 54th communication terminal M54.

After the call is received, the user of the 51st communication terminal M51 may make the call, or the control unit 15 of the 51st communication terminal M51 may read out the specified message and make the call.

In the second embodiment, an example has been described in which a user of a first communication terminal (e.g., the 54th communication terminal M51) inputs a first message, and the first message is transmitted from the first communication terminal to a second communication terminal (e.g., the 54th communication terminal M54) via the information server 30. Also, an example has been described in which the first communication terminal generates a second message and a third message, and the second message and the third message are transmitted from the first communication terminal to the second communication terminal via the information server 30.

However, the information server 30 may generate the second message and the third message, and the second message and the third message may be transmitted from the information server 30 to the second communication terminal.

In addition, the information server 30 may automatically generate the first to third messages and transmit the first to third messages to a second communication terminal (e.g., the 54th communication terminal M54). If there is no response from the second communication terminal or if an abnormality is detected in the biometric information of the user of the second communication terminal, the information server 30 transmits a predetermined message to the first communication terminal, etc. (third embodiment, see Figures 15 to 17).

In the following, the 51st communication terminal M51 will be described as a first communication terminal (a specified communication terminal) that receives a specified message from the information server 30, and the 54th communication terminal M54 will be described as a second communication terminal that receives the first message to the third message from the information server 30.
The first communication terminal that receives a predetermined message from the information server 30 in correspondence with the second communication terminal is recorded in advance in the server record unit 33 of the information server 30. For example, information (telephone number, e-mail address, etc.) of the communication terminal that receives a predetermined message from the information server 30 in correspondence with the second communication terminal is set in the contact information database D5.
Here, the first communication terminal that sends the specified message is described as the 51st communication terminal M51, but it may also be another communication terminal (for example, the telephone number of a neighbor (first related party) corresponding to the second call instruction area 302b).

The 54th communication terminal M54 displays the fifth screen P5 including the first message from the information server 30 (see Figure 15).

(Fifth screen P5)
The fifth screen P5 has a second back button 501 and a second message display area 503.
When the second back button 501 is clicked, the display is switched to the first screen P1.
The second message display area 503 has an area (second sending/receiving target display area 503a) that displays the name of the user to whom the message is being sent or received (here, the information server 30), and an area (second message content display area 503b) that displays the contents of the message.

The second message content display area 503b is provided with a second message input area 503b1 (area for inputting a text message), a second send button 503b2 for instructing transmission, a second image data transmission operation button 503b3 for transmitting image data such as a photograph, and a second audio data transmission operation button 503b4 for transmitting audio data such as recorded audio.

The second message input area 503b1 corresponds to the first message input area 403b1 of the fourth screen P4.
The second send button 503b2 corresponds to the first send button 403b2 on the fourth screen P4.
The second image data transmission operation button 503b3 corresponds to the first image data transmission operation button 403b3 on the fourth screen P4.
The second voice data transmission operation button 503b4 corresponds to the first voice data transmission operation button 403b4 on the fourth screen P4.

Figure 15 shows an example in which the text messages "Automatic transmission: Are you OK? (First message)", "Automatic retransmission 1: Are you OK? (Second message)", and "Automatic retransmission 2: Are you OK? (Third message)" are sent from the information server 30 to the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa), and then the text message "It's OK" is sent (responded) from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) to the information server 30, and these messages are displayed in the second message content display area 503b.
The screen display example in Figure 15 is displayed after a user with user ID: 23 (user name: Grandpa) logs in to the biometric information program installed on the 54th communication terminal M54 using user ID: 23.

(Safety Confirmation Control of the Third Embodiment)
The server control unit 35 of the information server 30 generates a message (first message) for confirming safety, and sends the first message to the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) (first message sending step, see step S31 in Figure 16).
In this case, it is preferable that the first message includes information indicating that the message is to be automatically sent by the biometric information program, such as "automatic sending."
The first message is transmitted periodically at a predetermined time interval (for example, between 7:00 and 8:00 every day). However, the first message may be transmitted non-periodically, for example, randomly.

The server control unit 35 of the information server 30 determines whether or not a response has been received from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) between the time the first message is sent and the time the first waiting time TT1 has elapsed (see steps S32 and S33 in Figure 16).

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 1 (an abnormality in the biometric information is detected), the server control unit 35 of the information server 30 notifies a specific communication terminal (first communication terminal) (first notification step, see steps S34 and S41 in Figure 16).
Specifically, the server control unit 35 of the information server 30 transmits a predetermined message to the 51st communication terminal M51 by SMS.
The predetermined message includes information that no response has been obtained from the user of the 54th communication terminal M54 and information that an abnormality has been detected in the biometric information of the user of the 54th communication terminal M54 (see FIG. 17). Note that the predetermined message may include information that an abnormality has been detected in the biometric information of the user of the 54th communication terminal M54, and omit the information that no response has been obtained from the user of the 54th communication terminal M54.
In addition, the specified message may include information showing the biometric information of the user of the 54th communication terminal M54 in chronological order, as shown on the second screen P2.
That is, the 51st communication terminal M51 receives notification from the information server 30 of at least one of information regarding the presence or absence of a response from the 54th communication terminal M54 to the information server 30, and information regarding the normal range of the biometric information of the user of the 54th communication terminal M54.

In addition, notification to the 51st communication terminal M51 may be made by the server control unit 35 of the information server 30 calling the 51st communication terminal M51, and after the call is answered, the server control unit 35 of the information server 30 reading out the specified message and making the call.

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 0 (no abnormality in the biometric information is detected), the server control unit 35 of the information server 30 sends a second message (second message sending step, see steps S34 and S35 in Figure 16).
In this case, it is preferable that the second message includes information indicating that the message is to be automatically resent by the biometric information program, such as "automatic resend 1."
It is also preferable that the sound output device of the 54th communication terminal M54 outputs a reception notification sound for a longer period of time and/or at a louder volume when the second message is received than when the first message is received.

The server control unit 35 of the information server 30 determines whether or not there is a response from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) between the time when the second message is sent and the time when the second waiting time TT2 has elapsed (see steps S36 and S37 in Figure 16).
If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 1 (an abnormality in the biometric information is detected), the server control unit 35 of the information server 30 notifies a specific communication terminal (first communication terminal) (second notification step, see steps S38 and S41 in Figure 16).

If there is no response from the 54th communication terminal M54 and the biometric information parameter rp of the user with user ID: 23 (user name: Grandpa) is 0 (no abnormality in the biometric information is detected), the server control unit 35 of the information server 30 sends a third message (third message sending step, see steps S38 and S39 in Figure 16).
In this case, it is preferable that the third message includes information indicating that the message is being automatically resent by the biometric information program, such as "automatic resend 2."
It is also preferable that the sound output device of the 54th communication terminal M54 outputs the reception notification sound for a longer period of time and/or at a louder volume when the third message is received than when the second message is received.

The server control unit 35 of the information server 30 determines whether or not there is a response from the 54th communication terminal M54 of the user with user ID: 23 (user name: Grandpa) between the time when the third message is sent and the time when the third waiting time TT3 has elapsed (see step S40 in Figure 16).
If there is no response from the 54th communication terminal M54, the server control unit 35 of the information server 30 notifies a predetermined communication terminal (first communication terminal) (third notification step, see step S41 in FIG. 16).
Specifically, the server control unit 35 of the information server 30 transmits a predetermined message to the 51st communication terminal M51 by SMS.
The predetermined message includes an indication that no response has been received from the user of the 54th communication terminal M54.

If no response is received from the second communication terminal even after the information server 30 automatically sends a message multiple times, the first communication terminal is notified. In other words, the first communication terminal is notified of the biometric information of another user (the user of the second communication terminal). Prior to this notification, messages are sent multiple times and the biometric information is checked for abnormalities. This makes it possible to prevent unnecessary notifications, such as when the first message notification was simply overlooked and there was no abnormality in the biometric information.

In the third embodiment, an example has been described in which, as an output of a first message or the like, the first message is displayed on the fifth screen P5 of the second communication terminal.
However, the output of the first message etc. is not limited to video but may be audio, that is, the audio output device of the 54th communication terminal M54 outputs the contents of the first message as audio.

In addition, an example has been described in which the specified message includes information regarding whether or not the biometric information of the user of the second communication terminal is outside the normal range, but in addition to or instead of this, biometric information of the user of the second communication terminal may also be included.
