Description

This invention relates to an information processing device and a program.

Conventionally, there are technologies for acquiring the location information of protected individuals and monitoring their movements. Patent Document 1 discloses a technology that determines whether a transmitter is a designated notification transmitter based on a signal from that transmitter, and if it is a designated notification transmitter, it issues a notification indicating that caution is required.

Japanese Patent Publication No. 2019-053417

In the technology described in Patent Document 1, whether or not a monitored person is a target for notification is determined based on attribute information such as whether the monitored person is a child or an elderly person, and information such as the monitored person's age. However, this technology only makes a judgment based on the monitored person's current data and does not refer to the monitored person's tendency for behaviors that warrant attention when deciding whether or not to issue a notification.

Therefore, the objective of the present invention is to control the transmission of notifications through monitoring based on behavioral trends derived from the monitoring subject's activity history.

According to the present invention,

A generation means that determines whether the monitored person tends to vary their walking speed based on their behavioral history, and generates trend information indicating the behavioral tendencies of the monitored person based on the behavioral history,
The system further comprises a second acquisition means for acquiring the aforementioned trend information,
The generating means determines whether the monitored person tends to walk rapidly, based on the frequency with which the monitored person's acceleration exceeds a predetermined threshold.
The transmission control means switches the transmission control based on the trend information , and if the monitored person tends to have varying walking speeds, it increases the level of vigilance in the transmission control.
An information processing device characterized by the above is provided.

According to this invention, it is possible to control the sending of notifications based on the behavioral trends of the monitored individual, derived from their activity history.

The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims, and not all combinations of features described in the embodiments are essential to the invention.

Furthermore, identical or similar configurations will be given the same reference numeral, and redundant descriptions will be omitted.

An information processing device according to one embodiment of the present invention monitors the location information of a person being monitored and switches the control of sending warning information to predetermined contacts based on the person's behavioral tendencies. In this embodiment, the information processing device is a server and controls whether or not to send warning information to the user of a vehicle traveling in the vicinity of the monitored person or to the monitored person's guardian. However, this is just one example, and the configuration is not limited to this example.

[system]
The system including the information processing device according to this embodiment will be described below with reference to Figure 1. Figure 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 connected to a mobile terminal 200 via a network 300 so as to be able to communicate.

In the monitoring service illustrated in Figure 1, the server 100 acquires location information of the first person 211, who is the person being monitored, from the mobile terminal 200a, and transmits information to a predetermined contact based on that location information. Here, the server 100 transmits the information to either an in-vehicle device 610 installed in the vehicle 600, or a mobile terminal 200b held by the second person 212, as the predetermined contact.

Here, vehicle 600 is a vehicle capable of transmitting various information to server 100 via an on-board device 610, and information about each vehicle is registered in server 100. In this embodiment, information including the location and identification information of vehicle 600 is managed by server 100. For example, if a first person located near vehicle 600 is determined to be a person of interest based on the tendency information described later, caution information is transmitted to vehicle 600.

Here, the second person 212 is a person (guardian) registered as the supervisor of the first person 211, who is the protected person, and is registered on the server 100 in association with the mobile terminal 200a so that information about the mobile terminal 200b is transmitted to the mobile terminal 200b. In this embodiment, "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 an obligation to protect and supervise, such as a parent, parent with parental authority, caregiver, person with a duty of support, contributor, curator, relative, supervisor, or leader. In contrast, "protected person" refers to a person who is protected and supervised by a guardian, regardless of whether they are related by blood, registered in the family register, or are a minor. In this embodiment, the protected person (person under supervision) is referred to as child 211, and the guardian (supervisor) as parent 212, and the following explanation will proceed accordingly. However, in other embodiments, the protected person and guardian may be "student" and "teacher," "child" and "community supervision volunteer," or "resident of a designated facility" and "manager/staff of a designated facility," respectively. In this example, child 211 and parent 212 are associated with each other, but one child 211 may be associated with multiple parents 212, and one parent 212 may be associated with multiple children 211. Furthermore, these associations can be changed at will.

The server 100 can control the transmission of warning information to predetermined contacts based on the location information of the child 211. Here, the server 100 may, for example, refer to the location information of the vehicle 600 and, for child 211 located in the vicinity of the vehicle 600 (for example, within a radius of 200m), transmit warning information to the vehicle 600 if the child 211 is a target for attention. Alternatively, for example, if the child 211 has entered (is located in) a predetermined area designated as having a high level of alert, such as a busy intersection or an accident site, and the child 211 is a target for attention, the server 100 may transmit a notification to the predetermined contacts. As control for transmitting warning information, the server 100 may turn notifications on or off, provide gradual notifications according to the level of alert, or perform the processing described in the following example; it is not limited to these processes.

The mobile terminals 200a and 200b, and the in-vehicle device 610, are equipped with a program for an application that provides monitoring services (a monitoring app). The processing performed by the monitoring app will be described as the transmission and reception of various information. Mobile terminals 200a and 200b are, for example, smartphones, data transmission and reception devices carried by the user. The in-vehicle device 610 is assumed to be a communication-capable device mounted on the vehicle 600, but is not particularly limited as long as it can present information to the user of the vehicle 600, such as a mobile terminal owned by a person designated 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 user of 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 storage unit 202, and a communication unit 203. The processing unit 201 is a processor, typically a CPU, which executes programs stored in the storage unit 202. The storage unit 202 is a storage device such as RAM, 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 program executed by the processing unit 201. The program may be installed on the server 100 from a storage medium such as a CD-ROM. In the example in Figure 2, databases (DBs) 221 to 223 are exemplified as data stored in the storage unit 202. DB 221 is a DB where information on the vehicle 600 is registered, and DB 221 is sometimes referred to as the vehicle DB. DB 222 is a DB where information on users such as child 211 and parent 212 is registered, and DB 222 is sometimes referred to as the user DB 222. In order to receive the services of this embodiment, the information stored in DB 221 and DB 222 must be registered in advance. DB 223 is a DB where other information such as map information is stored.

Note that DB221, DB222, and DB223 may be separate databases or combined into a single database. In this embodiment, for convenience, the databases are described separately, but this does not mean that they must exist as separate databases.

The vehicle database 221 stores records for each vehicle 600, managing vehicle information specific to each vehicle. This vehicle information is updated when the corresponding on-board device 610 is capable of location detection, by sequentially receiving location information from the on-board device. The records stored in the vehicle database 221 include a vehicle ID 321, current location 322, and contact information 323, as illustrated in Figure 3(b). Here, the vehicle ID 321 is identification information that uniquely identifies each vehicle 600. The current location 322 indicates the current location of the vehicle 600. The contact information 323 indicates the contact information used when transmitting information to the on-board device 610 of the vehicle 600. In other words, when warning information is transmitted to the contact information 323, the vehicle 600 receives a notification related to that warning information, informing the driver of the vehicle 600 that a child 211 is present in the vicinity.

The user database 222 stores records for each user, including child 211 and parent 212, and manages user information related to each user. This user information (particularly location information) is updated sequentially when the server 100 receives location information measured by the user's mobile terminal 200. The records stored in the user database 222 include, as illustrated in Figure 3(a), 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.

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

Furthermore, the protected user flag 304 is information indicating whether or not the user is a protected user. The protected user flag 304 may be, for example, a logical type of information, and if it is "True", it indicates that the user is a protected user, and if it is "False", it indicates that the user is a guardian. Whether a user is a protected user or a guardian is determined and managed based on the information entered during user registration and various settings when the monitoring application is launched on the mobile terminal 200. The linked user ID 305 is identification information (the user ID of the other user) that uniquely identifies other users linked with the user. Here, "linking" means associating the protected user and the guardian user with each other, and in this embodiment, the user ID of the parent 212 is stored in the linked user ID 305 for the child 211 user, and the user ID of the child 211 is stored in the linked user ID 305 for the parent 212 user. The contact information 306 includes the user ID and terminal information of the parent 212 that is linked to the child 211 user, or the email address and telephone number of the parent 212. In other words, contact information 306 is the recipient information to which warning information will be sent if the user of child 211 is in a designated 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 RAM or ROM. The programs stored in the storage unit 402 also include application programs for using the services 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 receives 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 constitute a touch panel display, but operation by mechanical switches or dials may also be possible. The GPS sensor 406 is a sensor that detects the current location 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. Except for the presence of an acceleration sensor 501, the mobile terminal 200 can be implemented with the same configuration as the in-vehicle device 610 shown in Figure 4; therefore, redundant explanations are omitted. The acceleration sensor 501 is a sensor for detecting the acceleration of the mobile terminal 200, and acceleration can be calculated using general acceleration detection techniques, such as detecting frequency changes using a quartz crystal oscillator.

[Monitoring Services]
In this embodiment, the server 100 acquires location information of the child 211 from the mobile terminal 200a and transmits warning information to a predetermined contact (in this case, a vehicle 600) according to the location information. For example, if the child 211 frequently violates traffic rules, such as crossing the road in a place other than a pedestrian crossing, the server 100 may consider the child 211 to be a person of interest and warn the users of nearby vehicles 600. From this perspective, the server 100 acquires trend information indicating the behavioral tendencies of the child 211 based on its behavioral history and switches the control of transmitting warning information based on the trend information.

The following describes the details of the processing performed by the server 100 in the monitoring service according to this embodiment. The processing unit 401 of the mobile terminal 200 transmits location information acquired by the GPS sensor 406 to the server 100 via the communication unit 403, for example, at predetermined time intervals. Upon receiving location information from each mobile terminal 200, the processing unit 201 of the server 100 updates the current location information 303 of the corresponding user information. Therefore, the location information transmitted from the mobile terminal 200 includes at least one of the user ID and the terminal ID.

In this embodiment, upon receiving the location information of child 211 and the location information of vehicle 600, it is determined whether child 211 is located in the vicinity of vehicle 600. That is, it is determined whether child 211 is in a location that requires attention from the user of vehicle 600 (if child 211 is a person of interest). Here, the area considered to be the vicinity of vehicle 600 may be, for example, a radius of 50m centered on vehicle 600, a radius of 100m, a radius of 200m, or it may be arbitrarily set. Furthermore, the distance at which child 211 is considered to be located in the vicinity of vehicle 600 (and therefore warning information is transmitted) may vary depending on the alert level set for child 211 (details described later).

Next, the server 100 obtains tendency information about child 211 from the child 211's behavioral history located around the child 211's vehicle 600. For example, if the server 100 finds that child 211 tends to vary in speed while walking, it can increase the level of vigilance, assuming that child 211 may suddenly start running. Each item of this tendency information is explained below.

As described above, the server 100 may designate child 211 as a person of interest if there is a tendency for the child's walking speed to fluctuate. Here, for example, the server 100 determines whether the frequency of the acceleration value of child 211 stored in the user DB 222 exceeding a predetermined threshold is high. The acceleration threshold used in this determination is not particularly limited as long as it can detect actions that warrant vigilance, such as child 211 suddenly running, but it may be 1.5 m/ ^s² , 2 m/s², or ³ m/ ^s² . Furthermore, "high frequency" means that the frequency of the acceleration value exceeding the predetermined threshold exceeds the predetermined frequency. Here, for example, the server 100 may refer to a history of accelerations stored in the user DB 222 in chronological order and determine that the frequency is high if a predetermined percentage or more (for example, 20%) of the acceleration value exceeds the predetermined threshold. Here, the server 100 may refer to a certain range (which can be specified), such as the most recent 100 updates of the user DB 222, or it may make a comprehensive determination of frequency using the entire history it holds.

Furthermore, if child 211 frequently violates traffic rules, server 100 may designate child 211 as a person of concern. Traffic rule violations may include, for example, proceeding without stopping at an intersection, crossing the road in a place other than a pedestrian crossing, or any other arbitrary conditions can be set. Whether or not child 211 stopped can be determined by known technology, but for example, server 100 may determine that child 211 did not stop if, while child 211 is located in the vicinity of the intersection (for example, within a 50m radius of the location set as an intersection), no moment is recorded where child 211's speed falls below the threshold used for stopping determination (for example, 2 km/h or less). The location of the intersection is assumed to be set on a map in advance, but for example, it may be individually set by the user, or any location where child 211 is recommended to stop, such as the location of a stop sign collected in advance, may be used. Alternatively, the mobile terminal 200 may determine whether child 211 stopped based on the speed detected by the mobile terminal 200 and transmit the determination result to server 100. Detection of road crossings in locations other than pedestrian crossings may be performed based on the location information of the child 211 and the location information of pedestrian crossings recorded by the server 100. Alternatively, the mobile terminal 200 may determine whether its location is on a pedestrian crossing when crossing the road and transmit this information to the server 100. The method is not limited to any method as long as such detection is possible. Furthermore, similar to the acceleration example, "high frequency" may refer to a high frequency based on a recent range of recorded traffic rule violations, or it may refer to a high frequency determined comprehensively using the entire recorded history.

Furthermore, the server 100 may designate Child 211 as a person of concern if the frequency of evasive maneuvers by vehicles within a predetermined range of Child 211 is high. That is, if vehicles around Child 211 frequently brake suddenly or take evasive actions such as sudden steering, Child 211 can be designated as a person of concern, as it is exhibiting behavior that warrants caution. Here, the server 100 can consider a high frequency to be present if the number of evasive actions per predetermined period exceeds a predetermined number (for example, three or more times per month). Here, for example, a vehicle 600 located within a predetermined range of Child 211 (for example, a radius of 50m) detects sudden behavior, including sudden braking and sudden steering, as evasive maneuvers using a known technique involving an acceleration sensor (or gravity sensor) not shown in the vehicle 600, and sends the detection result to the server 100. However, the server 100 may also detect the occurrence of evasive maneuvers from the vehicle 600's location information.

Here, we have explained that server 100 designates child 211 as a person of concern if any of the above-mentioned items are frequently observed. However, the determination of whether or not a person of concern is made by combining evaluations of multiple items. For example, server 100 may add a warning level for each frequently observed item, and if the warning level exceeds a threshold, the child 211 may be designated as a person of concern. For example, server 100 may designate child 211 as a person of concern if a predetermined number of items (e.g., three) are frequently observed, and if the warning level, weighted and added for each item, exceeds a threshold, the child 211 may be designated as a person of concern. By adding warning levels with weights, it becomes possible to set items that are given more importance, make a comprehensive judgment on whether or not child 211 is a person of concern, and transmit warning information. Such weight settings can be arbitrarily made based on the user's desired conditions.

The server 100 transmits warning information to the in-vehicle device 610 when it determines that child 211, located near vehicle 600, is a person of interest. Here, the server 100 may switch the transmission control of the warning information on or off depending on whether child 211 is a person of interest, and may also switch the content of the warning information according to the calculated alert level for child 211.

Here, we will explain the system so that the content of the warning information transmitted is switched according to the alert level added for each item of trend information, as described above. In this embodiment, for example, the degree of alert is divided into three levels: low, medium, and high, according to the calculated alert level value, and notifications are displayed on the screen in different colors for each level. Here, for example, the alert level may be increased by 1 each time it is determined that the frequency of one item of trend information is high (initial value is 0), and the degree of alert may be divided into low, medium, and high when the alert level is 1 or less, 2 to 3, or 4 or more, respectively. The server 100 may also increase the alert level by one level each time it is determined that the frequency of one item of trend information is high. The server 100 changes the content of the notification displayed on the in-vehicle device's display, such as the color, according to the degree of alert. For example, on the display, a child 211 with a low level of alert will receive no warning or a safety notification (e.g., a green display), a child 211 with a medium level of alert will receive a warning notification (e.g., a yellow display) indicating that caution is needed, and a child 211 with a high level of alert will receive a warning (e.g., a red display) indicating that caution is needed. This display could be, for example, a map where an icon representing a child 211 with a mobile device 200a that has the monitoring app installed is always displayed, and the color of the display changes according to the level of alert; or a display corresponding to the highest level of alert among the children 211 within a predetermined range of the vehicle 600 (e.g., a pop-up notification, or a change in the color of the frame or vehicle icon); or a map area could be color-coded according to the level of alert of the children 211 within that area. Any desired notification format can be adopted as long as it can show the user the presence of children 211 with a high level of alert. By notifying the vehicle 600 of such cautionary information, it becomes possible to prevent traffic accidents.

Furthermore, the level of alert is not limited to three levels: low/medium/high. For example, a two-level setting (safe/alert) may be used, or a more detailed setting may be adopted, such as a 10-level scale from 0 to 9, or even a numerical setting including decimal points. Also, the alert level is not limited to the behavioral tendencies mentioned above; it may change when conditions are met that would generally place the child 211 in a situation requiring alert. For example, the server 100 may determine from the child 211's location information whether the child 211 is in a designated area such as a busy intersection, and increase the alert level if it is in such an area. The designated area may include areas designated as requiring high attention, such as busy intersections, intersections with poor visibility, and accident sites, as well as areas excluding school/cram school routes and acquaintances' homes, etc., which are individually set for each child 211. Information for each area may be pre-stored in the server 100's storage device 102, or it may be updated sequentially by obtaining update information from an external server, etc.

Furthermore, the server 100 may notify the user of the area requiring attention where the child 211 is located on the display of the in-vehicle device 610 (for example, on the map display for car navigation) by coloring or displaying text, or by playing sound or vibrating to indicate that it is an area requiring attention, or by combining these processes. While this example shows whether the area where the child 211 is located requires attention, it may also show whether a predetermined area centered on the child 211 requires attention, or the child requiring attention may be colored on the map (for example, red or flashing), and any processing is possible as long as a warning about the child 211 can be issued.

Next, an example of how warning information is displayed in the in-vehicle device 610 depending on whether or not the child 211 is a person of interest will be explained with reference to Figure 6. Figure 6 shows a schematic diagram of the screen displayed by the car navigation system.

In the example shown in Figure 6, the server 100 acquires the location information of each child 211 located within a predetermined range from the vehicle 600 and determines whether each child 211 is a person of interest, as described above. Here, three children, 601 to 603, are located within the predetermined range from the vehicle 600. Children 601 and 602 are identified as persons of interest and are displayed according to their respective levels of vigilance, but child 603 is not identified as a person of interest and therefore no warning is displayed.

Figure 7 is a flowchart showing an example of the transmission control processing performed by the server 100 according to this embodiment. The processing shown in Figure 7 is achieved, for example, by the CPU of the processing unit 401 reading a program held in the ROM or storage unit 202 into the RAM and executing it.

In S701, the server 100 obtains the current location information of vehicle 600 and the current location information of child 211. Here, the server 100 constantly obtains information from the in-vehicle device 610 running the application and the mobile terminal 200a, stores it in the database, and can refer to the current information of each. In S702, the server 100 determines whether child 211 exists in the vicinity of vehicle 600. If it exists, the process proceeds to S703; otherwise, the process returns to S701.

In S703, the server 100 selects one of the children 211 surrounding the vehicle 600 to be processed. In S704-S711, the server 100 determines whether the frequency of each item in the trend information is high or low for the child 211 being processed, and calculates the alert level based on the determination result. Note that no weighting of the alert level is performed here; if a single item is deemed to have a high frequency, the alert level is increased by 1.

In S704, the server 100 determines, based on the information referenced in S701, whether the frequency of the acceleration of the target being processed exceeding a predetermined threshold is high. If the frequency of the acceleration exceeding the predetermined threshold is high, the process proceeds to S706; otherwise, the process proceeds to S705. In S705, the server 100 increments the alert level of the target being processed by 1 and proceeds to S706.

In S706, the server 100 determines, based on the information referenced in S701, whether the subject of processing has a high frequency of violating traffic rules. If the frequency of traffic rule violations is high, processing proceeds to S708; otherwise, processing proceeds to S707. In S707, the server 100 increments the alert level of the subject of processing by 1 and proceeds to S708. If the subject has a high frequency of violating traffic rules in multiple areas (for example, frequently failing to stop at intersections and frequently crossing the road in places other than pedestrian crossings), the alert level may be incremented by 1 for each of these violations.

In S708, the server 100 determines, based on the information referenced in S701, whether the frequency of evasive maneuvers by vehicles within a predetermined range from the processing target is high. If the frequency of evasive maneuvers is high, the process proceeds to S710; otherwise, the process proceeds to S709. In S709, the server 100 increments the alert level of the processing target by 1 and proceeds to S710. Note that if there are multiple items with a high frequency of evasive maneuvers (for example, if the vehicle frequently brakes suddenly and also frequently swerves), the alert level may be incremented by 1 for each of these.

In S710, the server 100 determines whether the object to be processed is a high-risk object based on the calculated alert level. For example, the server 100 may determine that objects with an alert level of 2 or less are not high-risk objects, and objects with an alert level of 3 or more are high-risk objects. In S711, the server 100 determines whether all of the child objects 211 surrounding the vehicle 600 were processed in S703. If all child objects 211 were processed, the process proceeds to S712; otherwise, the process returns to S703.

In S712, the server 100 transmits warning information about the child 211, who has been identified as a person of concern, to the designated contact person and terminates processing. Here, the server 100 transmits a message to the in-vehicle device 610 indicating the presence of a person of concern, prompting the vehicle 600 user to view it.

This processing allows a system that transmits warning information based on the location information of a monitored person to acquire information indicating the monitored person's behavioral tendencies based on their activity history, and to switch the control of warning information transmission according to those tendencies. In particular, if the monitored person frequently engages in behavior requiring caution, the level of caution can be increased. Therefore, the vehicle user can become aware of the presence of the child 211 requiring caution and take preventative actions such as reducing speed or honking the horn to avoid an accident.

In this embodiment, instead of determining whether the child 211 is located near the vehicle 600 as described above, it may be determined whether the location indicated by the location information of the mobile terminal 200 (the location of the child 211) is included in a predetermined area. That is, it may be determined whether the child 211 is located in a predetermined area. The predetermined area is, as described above, a busy intersection or an intersection with poor visibility. In this case, the recipient of the warning information (a predetermined contact) may be the mobile terminal 200b owned by the parent 212. Furthermore, while the mobile terminal 200b exemplified in Figure 1 is the recipient of information notification, it does not necessarily have to be a terminal that the user can carry; any device capable of running the monitoring application, such as a personal computer (PC), can be used.

The server 100 in this embodiment is just one example of an information processing device; for example, an information and communication terminal used by an event organizer at an event venue may perform similar processing. In this case, the selection process is executed by a CPU (not shown) built into the information and communication terminal, which loads the selection process program recorded on a storage device such as an HDD into RAM. The selection process program executed by the CPU may be installed on the information and communication terminal's storage device via a storage medium such as a CD-ROM.
