Description

The present invention relates to an information processing device and a program.

Conventionally, there is technology for obtaining location information of protected persons and monitoring their movements. Patent Document 1 discloses a technology in which a receiver is provided on the route to school to receive a detection signal from a transmitter carried by a child, and if the detection signal is not detected for a predicted movement time, a notification is issued that the child is not on the route to school. In Patent Document 1, when children are traveling to or from school in a group, the predicted movement time is set based on the grade level of the students in that group.

JP 2015-179433 A

However, the technology described in Patent Document 1 only uses the predicted movement time of the lowest-grade student in the group, and does not take into account the risks of group activities. In other words, it does not take into account the possibility that children acting in groups may behave carelessly and thus behave more dangerously than predicted.

Therefore, the object of the present invention is to enable a monitoring service to control notifications depending on whether or not the monitored subject is engaged in collective behavior.

According to the present invention,
a first acquiring means for acquiring location information from a first portable terminal of a first person, and acquiring location information of a second person from a second portable terminal that is present within a predetermined range from the first portable terminal ;

An information processing device according to one embodiment of the present invention monitors the location information of a person to be monitored, and when the person is engaged in group activities, switches the control content of sending information to a specified contact. In this embodiment, the information processing device is a server, and for a protected person engaged in group activities, the degree of warning sent to users of vehicles traveling near the protected person or the protected person's guardian is increased, but this is one example and is not particularly limited to this.

[system]
A system including an information processing device according to this embodiment will be described below with reference to Fig. 1. Fig. 1 is a diagram showing the configuration of a monitoring system that provides a monitoring service according to this embodiment. The information processing device according to this embodiment is a server 100, which is communicably connected to a mobile terminal 200 via a network 300.

In the monitoring service illustrated in FIG. 1, the server 100 acquires location information of the first person 211 who is to be protected from the mobile terminal 200a, and transmits the information to a specified contact when the first person 211 is in a specified area. Here, the server 100 transmits the information to the in-vehicle device 610 mounted on the vehicle 600, or the mobile terminal 200b of the second person 212, as the specified contact.

Here, the vehicle 600 is a vehicle capable of transmitting various information to the server 100 by the in-vehicle device 610, and each vehicle information is registered in the server 100. In this embodiment, information including the location information and identification information of the vehicle 600 is managed by the server 100, and for example, when the second person 212 is present in a specified area, a notification is sent to the vehicles 600 located in the vicinity of the second person 212.

Here, the second person 212 is a person (guardian) registered as the first person 211, and is registered in association with the server 100 so that information about the mobile terminal 200a is sent to the mobile terminal 200b. In this embodiment, the "guardian" refers to a person who is in a position to protect and supervise a specific person, or a person who temporarily acts as a substitute for protection and supervision, regardless of whether they have a duty of protection or supervision, such as a parent, parental authority, caregiver, person obligated to support, contributor, curator, relative, supervisor, or chaperone. In contrast, the "protected person" refers to a person who is protected and supervised by a guardian, regardless of whether they are related by blood or family register, or whether they are a minor. In this embodiment, the following description will be given assuming that the protected person is the child 211 and the guardian is the parent 212, but in another aspect, the protected person and guardian may be a "student" and a "teacher," a "child" and a "community monitoring volunteer," or a "resident of a specific facility" and a "manager/staff member of a specific facility," respectively. In this example, the children 211 and the parents 212 are associated with each other, but multiple parents 212 may be associated with one child 211, and multiple children 211 may be associated with one parent 212. Furthermore, the registration of these associations can be changed as desired.

When the child 211 enters (is present in) a specific area that has been set in advance as being high risk, such as a busy intersection or an accident scene, the server 100 can send a notification to that effect to a specific contact. When sending information, the server 100 may turn notifications on/off, may send notifications in stages according to the level of risk, or may perform the processes described in the following examples, but is not limited to these processes.

The mobile terminals 200a and 200b and the in-vehicle device 610 have installed therein an application program (monitoring app) that provides a monitoring service, and the transmission and reception of each piece of information will be described as a process performed by the monitoring app. The mobile terminals 200a and 200b are terminals that are carried by users and capable of transmitting and receiving data, such as smartphones. The in-vehicle device 610 is assumed to be a communicable device mounted on the vehicle 600, but is not particularly limited as long as it is capable of presenting information to the user of the vehicle 600, such as a mobile terminal owned by a person set as the user of the vehicle 600 or a mobile terminal linked to the vehicle 600. In other words, in the following description, information notified via the in-vehicle device 610 of the vehicle 600 may also be notified to the vehicle 600 via a mobile terminal.

Figure 2 is a block diagram showing an example of the hardware configuration of the server 100 according to this embodiment. The server 100 includes a processing unit 201, a memory unit 202, and a communication unit 203. The processing unit 201 is a processor such as a CPU, and executes programs stored in the memory unit 202. The memory unit 202 is a storage device such as a RAM, a ROM, or a hard disk. The communication unit 203 includes a wired or wireless communication interface capable of communicating with the in-vehicle device 610 or the mobile terminal 200 via a communication network.

The storage unit 202 stores various data in addition to the programs executed by the processing unit 201. The programs may be installed in the server 100 from a storage medium such as a CD-ROM. In the example of FIG. 2, databases (DB) 221 to 223 are illustrated as examples of data stored in the storage unit 202. DB 221 is a DB in which information about the vehicle 600 is registered, and DB 221 may be called a vehicle DB. DB 222 is a DB in which information about users such as child 211 and parent 212 is registered, and DB 222 may be called a user DB 222. To receive the service of this embodiment, the information stored in DB 221 and DB 222 must be registered in advance. DB 223 is a DB in which other information such as map information is accumulated.

Note that DB221, DB222, and DB223 may each be separate databases, or may be combined into one database. In this embodiment, for convenience, the databases are described separately, but this is not limited to each existing as a separate database.

The vehicle DB 221 stores a record for each vehicle 600, and manages vehicle information related to each vehicle. When the corresponding in-vehicle device 610 is in a state where the location can be detected, the vehicle information is updated by sequentially receiving position information from the in-vehicle device. The records stored in the vehicle DB 221 include a vehicle ID 321, a current position 322, and a contact 323, as illustrated in FIG. 3(b). Here, the vehicle ID 321 is identification information that uniquely identifies each vehicle 600. The current position 322 is information indicating the current position of the vehicle 600. The contact 323 is information indicating the contact used when transmitting information to the in-vehicle device 610 of the vehicle 600. In other words, when warning information is transmitted to the contact 323, a notification related to the warning information is issued in the corresponding vehicle 600, and the driver of the vehicle 600 can be informed that a child 211 is present in the vicinity.

User DB 222 stores records for each user, including children 211 and parents 212, and manages user information relating to each user. This user information (particularly location information) is updated sequentially as the server 100 receives location information measured on the mobile terminal 200 used by the user. The records stored in user DB 222 include a user ID 301, a terminal ID 302, a current location 303, a protected user flag 304, a linked user ID 305, and contact information 306, as exemplified in FIG. 3(a).

Here, user ID 301 is identification information that uniquely identifies each user. Furthermore, used terminal ID 302 is identification information that uniquely identifies the mobile terminal used by the user, such as the terminal identification information, MAC address, or IP address of the mobile terminal. Current location 303 is information that indicates the current location of the user. Current location 303 is sequentially updated as the server 100 receives location information measured on the mobile terminal 200 used by the user, and is managed as the current user's location information.

The protected flag 304 is information indicating whether the user is a protected person or not. The protected flag 304 may be, for example, logical information, and indicates that the user is a protected person when it is "True", and indicates that the user is a guardian when it is "False". Whether the user is a protected person or a guardian is determined and managed based on information input at the time of user registration or various settings, which is performed when the monitoring app is started on the mobile terminal 200. The linked user ID 305 is identification information (user ID of the other user) that uniquely identifies another user linked with the user. Here, "linking" refers to associating a protected user with a guardian user, and in this embodiment, the user ID of the parent 212 is stored in the linked user ID 305 for the user of the child 211, and the user ID of the child 211 is stored in the linked user ID 305 for the user of the parent 212. The contact information 306 includes the user ID and terminal information of the parent 212 who is linked to the user of the child 211, or the email address and phone number of the parent 212. That is, contact information 306 is information about the destination to which warning information is sent when the user of child 211 is in a specified area.

Figure 4 is a block diagram showing an example of the hardware configuration of the in-vehicle device 610 according to this embodiment. The in-vehicle device 610 includes a processing unit 401, a storage unit 402, a communication unit 403, an input unit 404, a display unit 405, and a GPS (Global Positioning System) sensor 406. The processing unit 401 is a processor such as a CPU, and executes programs stored in the storage unit 402. The storage unit 402 is a storage device such as a RAM or ROM. The programs stored in the storage unit 402 also include application programs for using the service of this embodiment.

The communication unit 403 is a wireless communication device capable of communicating with the information processing device 2 via a communication network. The input unit 404 is a device that accepts input from the user 5. The display unit 405 is an electronic image display device equipped with an input function. In this embodiment, the input unit 404 and the display unit 405 form a touch panel display, but may also be operable using, for example, a mechanical switch or dial. The GPS sensor 406 is a sensor that detects the current position of the mobile terminal 200.

Figure 5 is a block diagram showing an example of the hardware configuration of the mobile terminal 200 according to this embodiment. The mobile terminal 200 can be implemented with the same configuration as the in-vehicle device 610 shown in Figure 4, except that it has a short-range communication unit 501 and an acceleration sensor 502, so duplicated explanations will be omitted. The mobile terminal 200b according to this embodiment can perform short-range wireless communication with another mobile terminal 200b by the short-range communication unit 501. Here, the communication method of the short-range wireless communication will be described as ad-hoc communication such as Bluetooth (registered trademark), UWB, ZigBee (registered trademark), etc., but it is not limited to these and may be any method that wirelessly connects devices located in a short distance. The mobile terminal 200b according to this embodiment refers to the communication state by short-range wireless communication to determine whether or not there is another mobile terminal 200b linked to it, but detailed explanations will be omitted. Additionally, the acceleration sensor 502 is a sensor for detecting the acceleration of the mobile terminal 200, and is capable of calculating the acceleration using general acceleration detection technology, such as detecting frequency changes using a quartz crystal oscillator.

[Monitoring Service]
The server 100 according to this embodiment acquires location information of the child 211 from the mobile terminal 200b, and transmits information to a predetermined contact (here, the vehicle 600) when the child 211 is in a predetermined area. When the child 211 is engaged in group behavior, it is considered that the child 211 is less attentive to the surroundings, such as when talking with friends, compared to when the child 211 is traveling alone. From this viewpoint, the server 100 according to this embodiment acquires group behavior information on whether the child 211 to be monitored is engaging in group behavior with other children 211, and switches control of transmitting information to the predetermined contact when the child 211 is engaging in group behavior.

Below, the details of the processing performed by the server 100 in the monitoring service according to this embodiment will be explained. The processing unit 401 of the mobile terminal 200 transmits the location information acquired by the GPS sensor 406 to the server 100 via the communication unit 403, for example at a predetermined time interval. When the processing unit 201 of the server 100 receives the location information from each mobile terminal 200, it updates the information of the current location 303 of the corresponding user information. For this reason, at least one of the user ID and the terminal ID used is attached to the location information transmitted from the mobile terminal 200.

In this embodiment, when location information (child 211's location information) is received from mobile terminal 200a used by child 211, mobile terminal 200 determines whether the location indicated by the location information is included in a predetermined area. That is, it determines whether child 211 is in a predetermined area. The predetermined area may include areas determined to be high-risk, such as busy intersections, intersections with poor visibility, and accident sites, as well as areas set individually for each child 211, such as areas excluding school/cram school routes and acquaintances' homes. Information on each area may be stored in advance in storage device 102 of server 100, for example, or may be updated sequentially by obtaining update information from an external server, etc.

When the child 211 is in a specified area, warning information about the child 211 is sent to the contact point related to the vehicle within the specified range, which is set as the specified contact point. Here, vehicles within a specified range (for example, a radius of 300 m, which can be set arbitrarily) from the current location of the child 211, or vehicles in or around the specified area, are set as the specified contact points to which the server sends information. In the following, when a "vehicle" is mentioned as a contact point, any of these may be used. The warning information according to this embodiment may be information that notifies the user of the vehicle 600 when it is determined that there is a high risk of a traffic accident between the vehicle 600 and the child 211 (for example, the child 211 may run out onto the road). By notifying the vehicle 600 of such warning information, it is possible to prevent a traffic accident from occurring.

The server 100 according to this embodiment may, for example, set the process of transmitting warning information to the vehicle 600 to ON when the child 211 is acting in a group. In this case, when the child 211 is acting in a group, information indicating that the area is dangerous is transmitted to the vehicle 600. Here, the server 100 may notify the dangerous area in which the child 211 is located by coloring or displaying a character string on the display of the in-vehicle device 610 (for example, on the display of a map for car navigation), or may notify the danger by playing a sound or vibrating, or may combine these processes. Note that here, it is assumed that the display is made as to whether the area in which the child 211 is located is dangerous, but for example, it may be possible to display whether a predetermined area centered on the child 211 is dangerous, or to display the child acting in a group in color (for example, red or blinking) on the map, and any process can be performed as long as a warning can be given to the child 211.

In addition, when a child 211 is acting in a group, the server 100 may increase the level of warning for that child 211 in the warning information sent to the vehicle 600. That is, it is possible to perform a gradual warning notification rather than simply turning the warning notification on and off. In this case, for example, the server 100 sets a danger level for the child 211 based on whether the child 211 is acting in a group, the location information of the child 211, information on the area the child 211 has entered, or information set for the child 211, and issues warning information according to the danger level.

An example of the above-mentioned danger level will be described below. In this embodiment, for example, three levels of danger level are set, low/medium/high, and the display will display a different color for each danger level. The server 100 sets the initial danger level of each child 211 (or area) to "low" and can increase the danger level by one when a predetermined condition is met. The predetermined condition may be met, for example, when the child 211 is acting in a group, when the child 211 enters a predetermined area that is considered dangerous, when the acceleration of the child 211 exceeds a predetermined threshold value (which can be set arbitrarily), or when other conditions used in general monitoring technology to determine whether the monitored subject is in a dangerous situation are met. In this case, for example, on the display of the in-vehicle device 610, no warning is given for the child 211 walking alone, or a safety notification (e.g., green display) is given, a vigilance notification indicating that caution is required for the child 211 acting in a group outside a specified area is given (e.g., yellow display), and a warning (e.g., red display) is given for the child 211 who enters a specified area while acting in a group. This display may be, for example, a form in which an icon indicating the child 211 having the mobile terminal 200b with a monitoring app installed is always displayed on the map, and the color of the display may be changed according to the degree of danger, or a form in which a display is made according to the highest degree of danger among the children 211 present within a specified range of the vehicle 600 (e.g., by a pop-up notification, or by changing the color of the icon indicating the frame or vehicle), or a form in which a color is displayed according to the degree of danger of the child 211 within each area on the map, and any desired notification form can be adopted as long as the presence of the child 211 at high risk can be presented to the user.

The risk level is not limited to three levels, low/medium/high, and may be set to two levels, for example, safe/dangerous, or may be set to ten levels from 0 to 9, or may be set to more detailed levels, such as a numerical setting with a decimal point. These risk levels may be increased by more than one level when a certain condition is met. For example, when the risk level varies depending on the acceleration of the child 211, a value that varies depending on the acceleration may be calculated. By setting the risk level high when the acceleration of the child 211 increases, it is possible to notify the child 211 of danger when, for example, the child 211 suddenly starts running or jumps onto a curb, which may cause the child 211 to playfully jump out onto the roadway. The risk level may also vary depending on the number of children 211 in a group of children 211 who are acting in a group. In this case, the risk level can be increased, taking into consideration that the more people in a group, the more likely the child is to become distracted. The acceleration is detected by an acceleration sensor included in the mobile terminal 200b and transmitted to the server 100, but it can also be calculated by the server 100 based on, for example, the position information of the child 211 at each time.

Next, the process of acquiring group behavior information indicating whether the child 211 is engaged in group behavior will be described with reference to FIG. 6(a) to FIG. 6(b). The server 100 according to this embodiment can acquire group behavior information based on the location information of the child 211 and the child 211 that is linked to the mobile terminal 200b that is present within a predetermined range from the child 211 or that is carried by the child 211.

In the example of FIG. 6, the server 100 uses the movement direction of each child 211 calculated from the position information of that child 211 to determine whether or not the child 211 is engaged in group behavior. The predetermined range set here can be set arbitrarily as a range that can be considered for positioning as a group, and may be, for example, within a radius of 3 meters.

The mobile terminal 200b can determine whether it is linked to another mobile terminal 200b and transmit the determination result to the server 100. In this embodiment, the mobile terminal 200b is "linked" to mean a state in which the mobile terminals 200b are connected to each other via short-range wireless communication. Here, the mobile terminal 200b may determine that it is linked to the other mobile terminal 200b, for example, if a response from the other mobile terminal 200b is returned within a set time, depending on the signal strength of the connection via short-range wireless communication. This process makes it possible to refer to the communication state between the mobile terminals and determine whether they are moving in the same direction relative to the linked target.

The server 100 according to this embodiment calculates the direction of movement of each child 211. Next, the server 100 determines whether the movement directions of two people who are within a specified range or whose mobile terminals 200b are linked are the same, and if they are heading in the same direction, it determines that the child 211 is taking part in a group activity. In other words, if the children 211 are moving in the same direction, it determines that they belong to the same group and are taking part in a group activity.

Here, the server 100 can determine that the children 211 are engaged in group behavior when the difference in the movement direction of each child 211 on the map is within a predetermined angle (e.g., 30°). Also, for example, the server 100 can classify the movement direction of the children 211 on the map into a predetermined number of categories (four categories: north/east/south/west, two categories: before/after the route, or eight categories, etc.), and determine that the children 211 are engaged in group behavior when there is a child 211 in the same category.

In FIG. 6, children 601 and 602 are walking side by side and are determined to be moving in the same direction, so the in-vehicle device of vehicle 600a is notified that child 601 is acting in a group and caution is required. On the other hand, children 603 to 605 are moving in the opposite direction to children 603 and 604, and children 603 and 605 are moving in the same direction but are walking apart (the distance between the people is not within a specified range), so none of them are acting in a group and the user of vehicle 600b is notified that it is safe.

In this example, the server 100 judges whether the child 211 is engaged in group behavior based on each piece of location information, but for example, the mobile terminal 200b may judge whether the child 211 possessing the mobile terminal 200b is engaged in group behavior and transmit the judgment result to the server 100 as group behavior information. For example, when there is a mobile terminal 200b that is maintained in a connected state (linked) for a predetermined time or more by short-range wireless communication, the mobile terminal 200b may judge that the mobile terminal 200b is a terminal possessed by the child 211 engaged in group behavior. Also, for example, the mobile terminal 200b may check the connection state with other mobile terminals 200b at predetermined time intervals,

In addition, groups of children 211 may be registered in advance on the server side (or the mobile terminal side), and when children 211 registered in the same group are within a predetermined range or the mobile terminals 200b they carry are linked, it may be determined that the children 211 are engaged in group behavior.

Figure 7 is a flowchart showing an example of a notification process performed by the mobile terminal 200b according to this embodiment. The process according to Figure 7 is realized, for example, by the CPU of the processing unit 401 reading a program stored in the ROM or the storage unit 402 into the RAM and executing it. Note that, for the process according to Figure 7, a monitoring app is launched in advance on the mobile terminal 200b in order to use this monitoring service.

In S701, the mobile terminal 200b determines whether or not there is a mobile terminal 200b linked to the mobile terminal 200b. If there is, the process proceeds to S702, and if there is not, the process proceeds to S703. In S702, the mobile terminal 200b records information indicating the mobile terminal 200b linked to the mobile terminal 200b, and the process proceeds to S703. In S703, the mobile terminal 200b transmits to the server 100 the current location information obtained by the GPS sensor 406 and, if recorded in S702, information indicating the linked mobile terminal 200b, and ends the process.

Figure 8 is a flowchart showing an example of a transmission control process performed by the mobile terminal 200b according to this embodiment. The process shown in Figure 8 is realized, for example, by the CPU of the processing unit 401 reading a program stored in the ROM or the storage unit 202 into the RAM and executing it. In the example shown in Figure 8, the risk level for the child 211 is set to three levels: low/medium/high, with the initial value being set to "low."

In S801, the server 100 acquires the information transmitted from the mobile terminal 200b in S703. In S802, the server 100 determines whether the information acquired in S801 includes information indicating the mobile terminal 200b that is linked to the mobile terminal 200b. If it does, the process proceeds to S803, and if it does not, the process proceeds to S808.

In S803, the server 100 calculates the movement direction for each child 211 having the linked mobile terminal 200b. Here, the server 100 can calculate the movement direction of the child 211 based on, for example, current location information and location information from 10 seconds ago. In S804, the server 100 determines whether the movement directions calculated in S803 are the same direction. If they are the same direction, the process proceeds to S805, and if not, the process proceeds to S806. In S805, the server 100 increases the risk level for the child 211 by one and proceeds to S806.

In S806, the server 100 determines whether the child 211 is located in a specified area. If it is located in a specified area, the process proceeds to S807, and if it is not located in a specified area, the process proceeds to S808. In S807, the server 100 increases the risk level for the child 211 by one and proceeds to S808.

In S808, the server 100 determines the content of the information transmission control to a specified contact based on the risk level set for the child 211. Here, the server 100 issues a safety notification to the vehicle 600 in green if the risk level is low, issues a caution notification in yellow if the risk level is medium, and issues a warning in red if the risk level is high. In S809, the server 100 controls the transmission of the content determined in S808, and ends the process.

This type of processing makes it possible to control the sending of information to contacts depending on whether the person being monitored is engaged in group activities. In particular, if the person being monitored is engaged in group activities, it is possible to increase the level of warning given to nearby vehicles, as the person may be acting carelessly. Thus, the vehicle user will be able to recognize the presence of a child 211 who is engaged in group activities and requires caution, and will be able to take precautions to prevent accidents, such as slowing down or honking the horn.

In this embodiment, an example of sending information to an in-vehicle device as shown in FIG. 8 etc. has been described, but as described above, it is also possible to contact the guardian's mobile terminal 200a or the like as a specified contact point. In that case, the server 100 may increase the danger level by one level when the child 211 enters outside a predetermined range that is preset as the child's movement range, for example, and send a notification according to the danger level to the mobile terminal 200a of the parent 212. Also, the mobile terminal 200a illustrated in FIG. 1 is the destination of the information notification, but this does not necessarily have to be a terminal that the user can carry, and any device, such as a personal computer (PC), can be used as long as it is a terminal that can operate a monitoring app.

In the above example, the children 211 moving in the same direction are determined to be engaged in group behavior, but if they are moving by train or car, for example, they do not require attention even if they meet the above-mentioned conditions. In consideration of such cases, the server 100 may perform filtering based on a predetermined condition and perform the above-mentioned information transmission control only for the children 211 who meet the condition. For example, if the speed of the children 211 is a predetermined speed or higher (e.g., 20 km/h or higher, 30 km/h or higher, or 40 km/h or higher), the information transmission process by the mobile terminal 200b as shown in FIG. 7 may not be performed, or the information transmission control process by the server 100 as shown in FIG. 8 may not be performed. Similarly, the above-mentioned filtering process may also be performed when the children 211 are determined to be underground (e.g., when the Z coordinate obtained by the GPS sensor 406 is a predetermined value or lower).

The conditions for calculating the risk level are not limited to those exemplified above. For example, it is possible to set a high risk level for a child 211 who is deemed to be prone to risky behavior based on his/her behavioral history. From this perspective, the server 100 may vary the risk level based on information set for the child 211 or information set for the vehicle 600. For example, the server 100 may save a log of warnings issued for each child 211 as history, and may increase the initial risk level by one level for a child 211 that has issued warnings more frequently than a predetermined frequency.

Note that the server 100 according to this embodiment is an example of an information processing device, and similar processing may be performed by an information communication terminal used by an event organizer at an event venue, for example. In this case, the selection processing is executed by a CPU (not shown) built into the information communication terminal expanding a selection processing program recorded in a storage device such as an HDD into a RAM or the like. Here, the selection processing program executed by the CPU may be installed in the storage device of the information communication terminal via a storage medium such as a CD-ROM.
