[0009] 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. Two or more features from the multiple features described in the embodiments may be combined arbitrarily. Furthermore, identical or similar configurations will be given the same reference numeral, and redundant descriptions will be omitted.

[0010] ≪First Embodiment≫ <System Configuration> Figure 1 shows an example of the configuration of system SY according to an embodiment. System SY comprises a server 1 and one or more (in this case, three) mobile terminals 2. Server 1 and each mobile terminal 2 can communicate with each other via a network N.

[0011] Server 1 comprises a processor 1a, memory 1b, and storage 1c. The processor 1a is a broad-sense processing unit that performs calculations to realize each function of Server 1, and includes, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), etc. Memory 1b is a storage medium that temporarily stores intermediate data used during the calculations of the processor 1a, and volatile storage media such as RAM (Random Access Memory) and ROM (Read Only Memory) can typically be used. Storage 1c is a storage medium that stores information necessary for the calculations of the processor 1a, such as programs and parameters, and data showing the results of said calculations, and non-volatile storage media such as HDD (Hard Disk Drive) and SSD (Solid State Drive) can typically be used.

[0012] Server 1 may further include an input unit such as hardware keys, software keys, or levers, and a display unit such as an LCD display or an OLED display, which the administrator of Server 1 can use to input or update necessary information. The administrator of Server 1 corresponds to the service providers described later, and the services are provided to individual mobile terminals 2 via the network N.

[0013] Assume that one or more mobile terminals 2 are each associated with one or more users U. Here, the association means that it is sufficient if the user U is registered as the owner of the mobile terminal 2 or the user U actually owns the mobile terminal 2. Each mobile terminal 2 includes a processor 2a, a memory 2b, and a storage 2c. The processor 2a, the memory 2b, and the storage 2c may be configured to be able to realize functions similar to those of the processor 1a, the memory 1b, and the storage 1c, respectively. As the mobile terminal 2, well-known portable terminals such as smartphones, tablet terminals, and wearable devices can typically be used.

[0014] Each mobile terminal 2 further includes a microphone 2d and a position information specifying unit 2e. The microphone 2d can acquire sound information around the user U in addition to the speech of the user U himself / herself by its sound collection function. The position information specifying unit 2e is configured to be able to specify the position information of its own device (the mobile terminal 2), and its function can be realized using, for example, GNSS (Global Navigation Satellite System).

[0015] The outline of the service in this embodiment is to promote the improvement of the safety awareness of the user U using the mobile terminal 2, and accordingly, to realize the improvement of the safety of the region (hereinafter referred to as this service). A program distributed from the server 1 can be installed on the mobile terminal 2 as a part of this service (hereinafter referred to as this program). Prior to receiving this service, the user U can usually download and install this program on the mobile terminal 2 via the network N. This service can be mainly used when the user U goes out with the mobile terminal 2. The user U is often a child (under 18 years old) going to school, but may also be an adult (18 years old or older).

[0016] <Regarding user registration for this service> In this embodiment, when using this service, it is assumed that the user U performs user registration in advance. Figure 2 is a flowchart showing an example of the processing content of the mobile terminal 2 during user registration. The steps of this flowchart can be mainly executed by the processor 2a. This flowchart can be started based on, for example, the activation of this program by an operation input to the mobile terminal 2, or based on the mobile terminal 2 installed with this program being powered on.

[0017] In step S2010 (hereinafter referred to as "S2010". The same applies to other steps described later), it is determined whether user registration exists. If the user has been registered, the process proceeds to S2020; otherwise (if the user has not been registered), the process proceeds to S2110. In S2020, although details will be described later, this service is started and this flowchart ends.

[0018] In S2110, user registration is accepted, and during this time, the user U can input necessary information (hereinafter referred to as user information) into the mobile terminal 2. User information is often personal information such as the name, date of birth, and email address of the user U, but in this embodiment, it may be information necessary to identify the age of the user U or elements related thereto (for example, school year). In S2120, it is determined whether the input of user information has been completed. If the input of user information has been completed, the process proceeds to S2130; otherwise, the process returns to S2110. In S2130, the input user information is transmitted to the server 1 via the network N, and then the process proceeds to S2020. The transmitted user information is stored in the storage 1c, and thereby the user registration is completed.

[0019] <Regarding the processing content in this service> - Processing content on the mobile terminal side Figure 3 is a flowchart illustrating an example of the processing performed by mobile terminal 2 when using this service. This flowchart may be initiated, for example, based on the launch of this program on mobile terminal 2 of registered user U, or based on the mobile terminal 2 being powered on.

[0020] In S3010, the location information of the mobile terminal 2 is transmitted to the server 1 as the location information of user U. This is made possible by the location information identification unit 2e (see Figure 1). In S3020, the presence or absence of a notification signal, as described below, is determined. The notification signal can be received from Server 1. If a notification signal is received from Server 1, the process proceeds to S3030; otherwise, it returns to S3010. In S3030, the notification described below is output in response to the notification signal from Server 1, and the process returns to S3010. The output of the notification only needs to be something that alerts User U in some way, and may be done by the alarm function of Mobile Terminal 2 or by the vibration function of Mobile Terminal 2. Incidentally, the content of the notification may be output by machine voice or the like, or text information indicating the content of the notification may be displayed on the display of Mobile Terminal 2.

[0021] - Server-side processing details Figure 4 is a flowchart illustrating an example of the processing performed by Server 1 when providing this service. The flowchart outlines how, when multiple users U are located in a given area, the higher-ranking user U is identified and prompts for support from the other users U. The following steps are mainly performed by Processor 1a. This flowchart may be initiated, for example, in response to the start of distribution of this program or the start of provision of this service.

[0022] In S4010, the location information of each registered user U is obtained. Here, the location information of user U can be identified based on the location information transmitted from the mobile terminal 2 (see S3010).

[0023] In S4020, it is determined whether or not any user U is located in a predetermined area. This determination can be made by associating the location information of user U obtained in S4010 with existing map data. The predetermined area is one that is pre-set in the map data, and in this embodiment, it is a warning area that requires attention when passing through. The warning area may be an area for which a warning has been issued by a local government or executive branch, but it may also be an area set on the server 1 side based on information provided by user U (or related parties), and a typical example of this is a pedestrian crossing. The warning area may also be expressed as an area requiring attention, or more broadly, as an area of ​​interest. If any user U (referred to as user U1 to distinguish it from other users described later) is in the alert area, proceed to S4110; otherwise, return to S4010.

[0024] In S4110, it is determined whether another user U (referred to as user U2 for distinction) is located in the alert area. Here, the location information of user U2 can be identified based on the location information transmitted from user U2's mobile terminal 2, similar to the location information of user U1 (see S4010). If another user U2 is located in the alert area, proceed to S4120; otherwise, return to S4010.

[0025] In S4120, it is determined whether user U1 holds a higher position in relation to user U2. This determination can be made based on the user information stored in storage 1c (see Figure 2). For example, if user U1's age is higher than user U2's age, user U1 is identified as holding a higher position. As another example, if user U1's grade level is higher than user U2's grade level, user U1 is identified as holding a higher position. If user U1 is identified as being in a superior position, proceed to S4130; otherwise, return to S4010.

[0026] In S4130, a notification signal is sent to user U1's mobile terminal 2. This notification signal corresponds to the notification signal in S3020 (see Figure 3).

[0027] In other words, if multiple users U are located in the alert area, Server 1 identifies the user with the higher position among them and sends a notification signal to the mobile terminal 2 of the user U identified as having the higher position (user U1 in the above example). Upon receiving the notification signal, Mobile Terminal 2 outputs a notification prompting support, for example, through its alarm function (see S3030). This allows the user U identified as having the higher position to appropriately support the other users U (user U2 in the above example). The support referred to here can be any auxiliary action that helps another user U (user U2 in the example above) successfully complete their passage through the restricted area, and may be described as assisting, guiding, or escorting.

[0028] In S4210, it is determined whether user U1 has supported user U2. If it is determined that user U1 has supported user U2, the process proceeds to S4220; otherwise, it returns to S4010.

[0029] Here, the determination in S4210 can be implemented, for example, based on the respective location information of users U1 and U2. For instance, the location information of users U1 and U2 can be obtained using the same procedure as in S4010, and the determination can be made based on the relative movement patterns of their positions. Specifically, if, while the positions of users U1 and U2 are moving within the surveillance area, user U1's position moves intermittently along the trajectory of user U2's position, it can be determined that support was provided by user U1. As another example, the determination in S4210 may be implemented based on voice information obtained by microphone 2d (see Figure 1), for example, by performing known voice analysis on the voice of user U1. Here, the voice information acquired by the mobile terminal 2 is sent to server 1 and voice analysis is performed by processor 1a. Specifically, if voices such as "You can cross" or "A car is coming" from user U1 are confirmed, it can be determined that support was provided by user U1. Note that user U's voice may be registered in advance, for example, during user registration.

[0030] The determination in S4210 can be made with high accuracy by referencing both the location information and the voice information mentioned above. For example, it can be determined whether the type of support provided by user U1 is in accordance with the content of the notification output in S3030, based on both the location information and the voice information. As an example, if the content of the notification output in S3030 is to encourage the user to speak to other users in the vicinity, the determination in S4210 can be made appropriately based on the voice information.

[0031] In S4220, a reward is given to user U1 when it is determined that user U1 has supported user U2. The provision of the reward here means associating the information of the reward with user U1, specifically making the information of the reward available for use by user U1 using the mobile device 2 (the term "use" here can be broadly interpreted to include presentation to a third party, private viewing, etc.). Typical examples of rewards include points that can be used at any store, but any kind of incentive is acceptable, regardless of whether it has monetary value. Alternatively, user U1's reward may be granted based on an application from the supported user U2. This application can be made, for example, by user U2 performing a predetermined operation input on their mobile device 2. In this case, if it is determined that user U1 has supported user U2, a confirmation notification may be output to user U2's mobile device 2. This allows server 1 to appropriately grant the reward to user U1.

[0032] In S4230, the support history for user U1 is recorded or updated. The support history only needs to show the actual support provided. Typically, the support history is the cumulative number of times support has been provided, but if a warning level is set in the warning area, the cumulative number may be weighted up based on that warning level. Furthermore, the support history for each user U can be initially set to "no history" when the user is registered. This support history may be additionally referenced when making the determination in S4120 (determining whether user U is in a superior position or not). In the example above, the determination in S4120 was shown to be made based on user U's age, but it is possible that user U1 may have no support history even if user U1 is older than user U2. For this reason, the support history may be referenced when making the determination in S4120. That is, the determination in S4120 should be made based on user U's age and / or support history.

[0033] <Summary> According to this embodiment, user U actively provides support within the warning area, thereby promoting improved safety awareness and contributing to accident prevention. Furthermore, this enables improved regional safety, which in turn contributes to regional revitalization and the development of a sustainable transportation system. In this embodiment, a warning area is shown as a typical example of a predetermined area where this service is mainly utilized, and a pedestrian crossing is shown as one example of such an area. The presence or absence of traffic lights at the pedestrian crossing is irrelevant, but this embodiment is particularly advantageous in the case of pedestrian crossings where traffic lights are not installed.

[0034] In this embodiment, the mobile terminal 2 functions as an information management device that manages information about user U. At least a portion of the processing performed by the processor 2a of the mobile terminal 2 may be performed by the processor 1a of the server 1; that is, the functions of the information management device can be realized by the server 1 and / or the mobile terminal 2. This is also true for other embodiments described later.

[0035] ≪Second Embodiment≫ In the first embodiment described above, for the sake of clarity, we described the case where a superior user U1 and a subordinate user U2 are located in the caution zone. In this case, it could be said that the subordinate user U2 has no opportunity to be rewarded and therefore has no motivation to install the program and use the service. For this reason, it would be preferable to provide the service in a way that creates a motivation to use it even when the user is not in a superior position.

[0036] Figure 5 is a flowchart showing an example of the processing content of Server 1. This flowchart, like the flowchart in Figure 4 described in the first embodiment, is initiated, for example, in response to the start of distribution of this program / start of provision of this service. Its general outline is to determine whether a predetermined action has been taken by User U when passing through a restricted area, and to grant a reward to User U if the predetermined action has been taken.

[0037] If S4020 determines that user U is located in the alert area, S5010 determines whether user U has performed a predetermined action. The predetermined action can be any action that involves checking the alert area or an equivalent action, and a typical example of this is the action of checking the left and right directions of user U (hereinafter referred to as the checking action). Here, the determination in S5010, like the determination in S4210, can be made based on the location information of user U. For example, if user U's location remains stationary for a predetermined period (e.g., several seconds) before it starts moving within the surveillance area, it can be determined that user U has taken a confirmation action. If the mobile terminal 2 is a wearable device (e.g., one that can be worn on the arm, head, etc.), the determination in S5010 can be made with high accuracy. If it is determined that user U has performed a confirmation action, proceed to S5020; otherwise, return to S4010.

[0038] In S5020, a reward is given to user U in accordance with the determination that user U has performed a confirmation action.

[0039] Furthermore, steps S5010 to S5020 in this flowchart may be performed in parallel with the steps from S4110 onwards in Figure 4.

[0040] According to this embodiment, even when user U is not in a superior position (as in the case of user U2 in the first embodiment), there is an opportunity to be rewarded, and there is also an opportunity to be rewarded for user U moving alone within the patrol area. Therefore, according to this embodiment, the service can be made widely usable (available to a wider range of users), and consequently, it becomes possible to further improve the safety of the area.

[0041] ≪Third Embodiment≫ In the first and second embodiments described above, for the sake of simplicity, we described the case where a total of two users U, U1 and U2, are located in the alert area. However, it is also possible that there are three or more users U located in the alert area. For example, if in addition to users U1 and U2, there is another user U (let's call this other user U3 for distinction) located in the alert area, and user U1 is the oldest and user U2 is the youngest, then user U3 may be in an intermediate position.

[0042] In such cases, user U3 is not necessarily required to receive a notification prompting them to provide support. However, if user U3 proactively provides support, this action can be seen as a reflection of user U3's high level of safety awareness. Therefore, in such cases, user U3 may be rewarded. Furthermore, whether or not user U3 provides support can be determined based on location information (and voice information), similar to the determination in S4210.

[0043] ≪Fourth Embodiment≫ According to the first embodiment described above, it is assumed that the person to be supported (user U2 in the example of the first embodiment) is already registered. However, user registration for the person to be supported is not mandatory; for example, the contents of the first embodiment can be realized by installing surveillance cameras connected to network N in or around the area of ​​surveillance.

[0044] Figure 6 shows an example of the configuration of system SY according to the fourth embodiment. In this embodiment, system SY further includes one or more (two in this case) surveillance cameras 9. Each surveillance camera 9 only needs to be able to communicate with server 1 and / or mobile terminal 2 via network N, and may be configured together with the communication device or separately. The surveillance cameras 9 are installed to correspond to any of the surveillance areas and so that the area they are monitoring includes the surveillance area / can monitor the surveillance area, and the monitoring results from the surveillance cameras 9 are transmitted to server 1.

[0045] In this embodiment, Server 1 can perform the determination in S4120 (determining whether User U is in a superior position) and the determination in S4210 (determining whether support is available) in the flowchart of Figure 4 based on the monitoring results of the surveillance camera 9.

[0046] In this embodiment, in S4120, it is determined whether user U is in a higher position or not based on the monitoring results received from the surveillance camera 9 (video showing multiple people located in the surveillance area, including user U; one or more still images may be used instead of video). This determination can be made by known image analysis. During image analysis, since there is no user information for the other people in the surveillance area other than user U, the determination in S4120 can typically be made based on a comparison of heights. In this case, an image of user U himself, used to identify user U, can be registered in advance, for example, during user registration.

[0047] Furthermore, in S4210, it is determined whether user U, who has been identified as being in a superior position, has supported another person, based on the monitoring results received from the surveillance camera 9. In the first embodiment described above, the determination in S4210 was made based on the location information (and voice information) of user U, but in this embodiment, where the behavior of user U can be evaluated in detail through image analysis, it can be said that this can be achieved with higher accuracy.

[0048] According to this embodiment, the person to be supported does not have to be a user of this service, and this service can be used when multiple people, including user U, are located in the alert area. More precisely, this service only requires that at least one of the multiple people located in the alert area be registered as a user, and registration of all of them is not required. If user U is identified as being in a higher position among such multiple people, user U will be notified to encourage support for the others (see S3030 and S4130).

[0049] ≪Fifth Embodiment≫ In the first embodiment described above, it is possible that the map data has not been updated and no new surveillance area has been set on the map data. In such a case, the monitoring results of the surveillance camera 9 shown in the fourth embodiment described above may be transmitted to the server 1 and / or the mobile terminal 2. In this case, the surveillance camera 9 is not installed in the surveillance area, but rather the area monitored by the surveillance camera 9 is set as a surveillance area when predetermined conditions are met.

[0050] For example, the surveillance camera 9 is equipped with an evaluation means capable of evaluating the level of alert in the area being monitored, and sets the area being monitored as an alert area based on the evaluation result. For example, if the volume of vehicles and / or people passing through a certain area meets a standard (for example, if the volume of vehicles exceeds the first standard volume, or if the volume of people passing through falls below the second standard volume), that area may be set as an alert area.

[0051] The information about the alert area, as configured in this way, is sent to server 1, which allows the map data to be updated by processor 1a. This configuration reduces the processing load on server 1 and also avoids significant changes to the existing infrastructure.

[0052] ≪Variations≫ Some or all of the above can be combined with each other, and in doing so, other components may be added as long as they do not deviate from the intent of these components, thereby making it possible to further improve the safety of the region. For example, according to the combination of the second to fourth embodiments, the person to be supported does not have to be a user of this service. Therefore, user U may have an incentive to actively provide support regardless of whether the person to be supported is a user of this service or not. This makes it possible to make this service widely available, and consequently, further improves local safety.

[0053] ≪Other≫ In the embodiments described above, the service is primarily implemented by the execution of a program by a processor. However, the invention is not limited to this, and for example, a dedicated portable terminal may be used instead of the mobile terminal 2 on which the program is installed. The dedicated portable terminal may be configured to have a processor capable of executing the program, or it may be equipped with an ASIC (Application-Specific Integrated Circuit) capable of performing equivalent functions. In other words, the processing content exemplified in the embodiments described above can be implemented by either hardware or software. Furthermore, the details illustrated in the above embodiments can be modified without departing from their intent, and for example, the order of the steps shown in some flowcharts may be partially changed.

[0054] In the above explanation, for the sake of ease of understanding, each element has been given a name related to its function. However, each element is not limited to having the content described in the embodiment as its primary function, but may also have it as a secondary function. Therefore, each element is not strictly limited to its expression, and its expression can be replaced with other similar expressions.

[0055] Furthermore, the two or more elements exemplified as selectable in the embodiment are not strictly limited to those examples and may be combined in any way. For example, the two or more elements listed by "and / or" may be additionally selected or alternatively selected. As an example, in the case of two elements A and B, the expression "A and / or B" indicates either A only, B only, or both A and B, and may be rephrased as "at least one of A and B."
