Information processing device, map display method, program, and map display system

Abstract

The present invention provides an information processing device, a map display method, a program, and a map display system that can improve the visibility of the status of each monitored object while reducing the operational burden on the monitor when displaying the location information of multiple monitored objects on a map. [Solution] The information processing device comprises a processor and a communication means. The processor receives location information from multiple GPS terminals via the communication means. It then performs a predetermined evaluation based on the location information of the GPS terminals and / or the current display status of the GPS terminals on the monitoring terminal. Based on the evaluation result, it determines the number of maps to be displayed on the display unit of the monitoring terminal. Information for displaying the determined number of maps on the display unit of the monitoring terminal is transmitted to the monitoring terminal via the communication means. This allows for automatic switching to multiple map display if displaying all monitored targets on a single map would result in an excessively small scale, or enables detailed display of maps for monitored targets with a high risk level.

Description

Technical Field

[0001] The present disclosure relates to an information processing apparatus, a map display method, a program, and a map display system.

Background Art

[0002] In recent years, in order to ensure the safety of children, the elderly, etc., a system that uses a GPS (Global Positioning System) terminal possessed by a target person and allows a monitor such as a protector to confirm the current position of the target person on a monitoring terminal such as a smartphone has been widely used. In such a system, based on the position information transmitted from the GPS terminal possessed by the monitored person, the position and movement history of the monitored person are displayed on the screen of the monitoring terminal together with a map.

[0003] For example, Patent Document 1 discloses a monitoring system that accumulates the position information of a terminal based on information uploaded from a terminal carried by a person under watch, determines the living area of the person under watch based on the accumulated position information, determines the positional relationship between the position of the terminal and the living area, and notifies the determination result to a pre-specified terminal (the protector's terminal).

Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each figure, the same or corresponding elements are denoted by the same reference numerals, and duplicate explanations will be omitted as appropriate. In this specification, main terms are defined as follows.

[0010] A "map" is a visual representation of geographical information and includes not only an independent display area that occupies the entire screen of a monitoring terminal (hereinafter also referred to as the "independent map display area"), but also partial map display areas such as inset maps and small window displays that appear on a part of the screen (hereinafter also referred to as the "inset map display area," etc.). The main map display area may also be referred to as the "base map display area."

[0011] The "number of maps" may refer to the number of independent map display areas that divide the entire screen, and may also refer to the number of partial map areas provided for individual detailed information displayed on the main map display area (base map), and may mean the number of areas of geographical information displayed from substantially different viewpoints or levels of detail. For example, in addition to the case where the display screen of the monitoring terminal is physically divided into a plurality of areas and different maps are displayed in each area, within a single main map display area, detailed information corresponding to each of a plurality of monitoring targets (including map information and related information at different scales) is presented simultaneously or selectively in a plurality of forms such as inset maps, pop-up windows, overlay displays, or switchable viewports. This may also correspond to a state where substantially multiple "map" information is displayed (i.e., a state where the "number of maps" is plural). Further, in an augmented reality (AR) environment, when a plurality of different geographical information areas are virtually displayed overlaid on the real space, if each geographical information area has an independent viewpoint and level of detail, it shall be considered to be included in the concept of the "number of maps" in the present disclosure. What is important is that a plurality of geographical information sets are provided in such a way that the monitor can efficiently grasp the situations of a plurality of monitoring targets at information granularities suitable for each of them. Further, even within a single physical map display area, when detailed geographical information regarding a plurality of monitoring targets is displayed by being switched over time, or when a display area focused on a specific monitoring target is dynamically generated and changed in response to a user operation or the like, if it can be evaluated that substantially multiple independent geographical information is provided from different viewpoints and levels of detail, these shall also be considered to correspond to a state where "the number of maps is plural" as a whole. This is because it enables the monitor to grasp the situations of individual targets at information granularities suitable for each of them, and as a result, contributes to an improvement in visibility that is difficult to achieve with a single static wide-area map, and is based on the same technical concept as physical screen division and simultaneous display of inset maps. Terms such as "predetermined evaluation", "current display state", "degree of danger", etc. will be specifically described in each of the embodiments described later.

[0012] The background of this embodiment will be briefly explained below. Conventional GPS monitoring systems, such as the one described in Patent Document 1 mentioned above, have the problem that when monitoring multiple targets simultaneously, it is difficult to fully grasp the status of each target within the limited screen size of the monitoring terminal. Specifically, when multiple targets are geographically separated, if one tries to fit all of them on a single map screen, the map scale becomes extremely small (wide-area display), making it difficult to grasp the specific situation around each target in detail (e.g., exact location, type of building, whether or not they are approaching a dangerous place).

[0013] To solve this problem, when a monitor manually selects a specific target and zooms in on the map of its surroundings, a new problem arises: the status of other targets may be off-screen or displayed very small, making it impossible to monitor their status in real time. To comprehensively grasp the status of multiple targets, monitors need to frequently switch screens and adjust the zoom level, resulting in a heavy operational burden. In particular, in situations where monitors cannot constantly monitor the screen (so-called "multitasking monitoring"), such as while driving or performing other tasks, this operational burden and the interruption in monitoring represented a significant area for improvement in ensuring safety. As a result, it became difficult to quickly and accurately determine whether individual targets were in dangerous situations, leading to a decline in the quality of monitoring and sometimes failing to adequately alleviate the monitor's anxiety.

[0014] Figure 1 is an overview diagram showing an example of the overall configuration of the monitoring system 100 according to this embodiment. The monitoring system 100 comprises GPS terminals 200A, 200B, etc. (hereinafter also referred to as GPS terminals 200) each possessed by a plurality of monitored persons M1, M2, etc. (hereinafter also simply referred to as monitored persons M), an information processing device 300 (e.g., a server device) that receives and processes information from these GPS terminals 200, and a monitoring terminal 400 (e.g., a smartphone, tablet terminal, PC, etc.) operated by the monitor U. These are connected to each other so as to be able to communicate with one another via a network 500 (e.g., the internet, a mobile phone network, etc.).

[0015] Figure 2 is a block diagram showing an example of the hardware configuration of the information processing device 300 according to this embodiment. The information processing device 300 can be configured as a general-purpose computer, comprising a CPU (Central Processing Unit) 301, RAM (Random Access Memory) 302, ROM (Read Only Memory) 303, a communication interface (I / F) 304, a storage device 305 (e.g., an HDD or SSD), and a bus 306 connecting these components. The CPU 301 controls the operation of the entire information processing device 300 by loading programs stored in the storage device 305 and ROM 303 into the RAM 302 and executing them, thereby realizing the processing of each functional unit described later. The communication I / F 304 sends and receives data to and from the GPS terminal 200 and the monitoring terminal 400 via the network 500. The storage device 305 stores the OS (Operating System), various application programs, and data necessary for processing (various tables, evaluation logic, log data, etc., described later). For example, the storage device 305 may store user information, GPS terminal information, location history of each GPS terminal, pre-configured dangerous area information, monitoring schedule information, facility information such as home and school, and display rule settings (for example, default settings for display size according to the level of danger, and custom settings by the user).

[0016] Figure 3 is a functional block diagram showing an example of the functional configuration of the information processing device 300. The information processing device 300 functions primarily as a communication unit 310, a location information receiving unit 320, an evaluation unit 330, a map number determination unit 340, and a display information transmission unit 350, through the execution of a program by the CPU 301. These "units" can be implemented by hardware, software, or a combination thereof. The processing steps and algorithms performed by each functional unit are described in detail throughout this specification. Program modules for implementing these functions are stored in the storage device 305 and executed by the CPU 301.

[0017] The communication unit 310 controls the transmission and reception of data with external devices (GPS terminal 200, monitoring terminal 400) via the communication interface 304. This performs a part of the function equivalent to "communication means".

[0018] The location information receiving unit 320 receives location information transmitted from each of the multiple GPS terminals 200 via the communication unit 310. The received location information, along with a timestamp, is stored as history in the storage device 305 and can be used not only for real-time or near-real-time evaluation, but also for evaluation for past behavioral analysis, as will be described later.

[0019] The evaluation unit 330 performs a "predetermined evaluation" based on the location information of the multiple GPS terminals 200 and / or the current display state of the multiple GPS terminals 200 on the monitoring terminal 400 (for example, the current map scale information received from the monitoring terminal 400, or the scale that would be expected if all GPS terminals 200 were displayed on a single map). Here, in this specification, when the information processing device "performs a predetermined evaluation based on" specific information (for example, the location information of the GPS terminals, the current display state of the GPS terminals on the monitoring terminal, etc.; hereinafter referred to as "evaluation target information"), it means that the evaluation target information is actively referenced as a parameter that can influence the evaluation result in the evaluation logic for determining the number of maps, and that changes in the value or state of the evaluation target information have an objectively recognizable influence, logically or statistically, on the final determination of the number of maps or the intermediate judgments leading to that determination. For example, this includes cases where the information to be evaluated is used as an input value for the evaluation logic, and the output of the evaluation function changes in accordance with the changes in that input value, or where the information to be evaluated is used as a branching condition for the evaluation logic, and different processing paths are selected depending on whether or not that condition is met. Even if other information (e.g., fixed rules on the server side, user pre-configurations, static importance parameters) is involved in the evaluation, as long as the information to be evaluated is incorporated into the evaluation process in a way that has the above-mentioned influence, the evaluation will be "based on". The evaluation unit 330 performs a "predetermined evaluation" based on the location information of the multiple GPS terminals 200, and / or the current display state of the multiple GPS terminals 200 on the monitoring terminal 400 (for example, the current map scale information received from the monitoring terminal 400, or the scale that would be expected if all GPS terminals 200 were displayed on a single map).

[0020] Furthermore, the "current display state of the multiple GPS terminals on the monitoring terminal" is not necessarily limited to the scale and layout information of the map actually displayed on the monitoring terminal's screen. It is a broader concept that includes display-related parameters that are held or set on the monitoring terminal and can serve as a basis for map display, such as the display scale (expected scale) that would inevitably be determined by the screen size and resolution of the monitoring terminal if all GPS terminals were displayed on a single map, or display presets set by the user in past operations or default display magnification for specific monitoring targets. Moreover, the monitoring terminal 400 may be configured to generate "display context information" such as the display scale of the main GPS terminals at that time, their location information on the screen, or the number of GPS terminals displayed on the screen, and transmit this information to the information processing device 300 when the user performs map operations (zooming in / out, scrolling, selecting a specific GPS terminal, etc.) or selects a display mode (e.g., list display, individual focus display, N-screen split display, etc. See Figure 14), in addition to simply the selected mode information. The evaluation unit 330 of the information processing device 300 uses the received "display context information" as one aspect of the "current display state of the multiple GPS terminals on the monitoring terminal" for evaluation (see Figure 17). For example, if a particular GPS terminal is displayed at a very large scale (detailed display), it is determined that the terminal is highly important, and if the display of other terminals is too wide, the system can maintain the display of the highly important terminal while reserving a separate map area for the other terminals (increasing the number of maps). The information processing device 300 records the display context information used in this evaluation and the judgment results based thereon as a log in the storage device 305. This log shall include information indicating the specific details of the received or estimated "current display state" (e.g., scale received from the monitoring terminal, list of GPS terminals to be displayed, user selection mode, etc.), which parameters of the evaluation logic were affected by the display state, and how (or did not change) the determination of the number of maps as a result. This log data can be used not only for verifying and debugging system operation, but also as objective evidence that the information processing device actually used the "current display state" for evaluation, and may be referenced as needed.This reduces the difficulty in identifying and proving the contribution of the "current display state" to the evaluation process within the information processing device.

[0021] Furthermore, in this specification, "predetermined evaluation" refers to a logical or empirical judgment process for determining the number of maps to be displayed on the monitoring terminal, the scale of each map, the display range, the layout, or whether or not highlighting is present, in order to achieve the objective of improving the ease and speed of monitoring by the monitor in understanding the situation of the monitored target, using as input the location information of multiple GPS terminals, and / or the current display status of the multiple GPS terminals on the monitoring terminal, as well as additional information that may be associated therewith (for example, static attributes linked to the GPS terminals, time, day of the week, pre-registered area information (see Figure 8), environmental information obtained from an external system, schedule information of the monitored target, real-time traffic information and weather information, etc.; see Figure 16). This decision-making process may include, for example, the degree of geographical dispersion of GPS terminals (scale evaluation), the safety of the surrounding environment of each GPS terminal (risk evaluation), the relative importance and urgency of each GPS terminal (evaluation based on static or dynamic importance parameters), the monitor's current operational intentions and areas of interest (evaluation of user display mode selection information), or the degree of deviation from past behavioral patterns (past log analysis evaluation), and detection of anomaly signs through machine learning of the positional relationships, movement speed, direction, and activity level change patterns of multiple monitored targets. Specific evaluation items and evaluation logic are not limited to those exemplified herein, and are included in the scope of "predetermined evaluation" as long as they are reasonably used to achieve the aforementioned objectives. Furthermore, the evaluation may also include whether or not the monitored target deviates from its schedule, and whether or not it is inside a pre-registered facility (e.g., home, school). In addition to the GPS terminal location information itself, additional information related to that location information that is used to determine the map display method can be collectively referred to as "situational information."

[0022] The "location information" that is the subject of the "predetermined evaluation" performed by the evaluation unit 330 is not limited to the latest location information received in real time or near real time from the GPS terminal 200, but also includes past location information history (log data) stored as history in the storage device 305. The evaluation unit 330 can analyze this location information history and extract specific behavioral patterns (for example, use of routes different from the usual, past approaches to specific dangerous areas, changes in the range of activity within a certain period, etc.) and make them the subject of "evaluation". Furthermore, regarding "the current display status of the multiple GPS terminals on the monitoring terminal", not only the display status in the strict sense of real time, but also the display context when the user is referring to the results of a specific past behavioral analysis, and the display settings specified by the user during past log analysis can be indirectly used in the evaluation as contextual information for the analysis. Furthermore, in accordance with the evaluation results based on such past behavioral analysis, the map number determination unit 340 determines the "number of maps" (for example, multiple maps showing multiple related locations or time periods, or multiple maps arranged in chronological order) that is suitable for presenting and allowing the user to confirm the past behavioral patterns and analysis results, and the display information transmission unit 350 transmits the corresponding information. This mode of operation is also included within the scope of the technical concept of this disclosure.

[0023] In this specification, "objectively recognizable influence" on the evaluation result of the information being evaluated means, for example, that if the information being evaluated is excluded from the evaluation logic, or if its value fluctuates beyond a predetermined range, the final determination of the number of maps changes with a statistically significant frequency or with a probability exceeding a predetermined threshold, all other conditions being equal. Conversely, if the information being evaluated is included in the evaluation logic, but does not substantially change the final determination of the number of maps (for example, if it is always overwritten by other dominant factors, or if the change can be considered within the margin of error), it is not interpreted as having been evaluated "based" on the information as used herein. This ensures that the information being evaluated functions not merely as a formal input, but as a substantive factor in determining the number of maps.

[0024] (Scale evaluation) The evaluation unit 330 evaluates the map scale when all monitored GPS terminals 200 are displayed on a single map display area on the display unit 401 (not shown) of the monitoring terminal 400. This evaluation is calculated based on the geographical dispersion of the latest location information of each GPS terminal 200 and the screen size information of the monitoring terminal 400 (either acquired in advance or received from the monitoring terminal 400). It then determines whether the calculated scale is below a "first predetermined scale" (e.g., 1 / 50000) that makes it difficult to identify detailed geographic information (e.g., the shape of individual buildings, narrow alleys, facility names, etc.). This "first predetermined scale" may be set in advance as a specific scale value, or it may be dynamically determined according to the screen resolution and display size of the monitoring terminal 400. A scale smaller than this indicates a level where it becomes difficult to grasp the surrounding situation of individual monitored targets M. Furthermore, the evaluation unit 330 may be configured to display a warning message (e.g., "The display is too wide. Do you want to switch to detailed display?") on the monitoring terminal 400 when the calculated scale approaches the "first predetermined scale" and, for example, enters a range of 120% of it, prompting the user to choose to increase the number of maps. In this case, the user's choice itself is considered part of the "predetermined evaluation" (part of the current display state), and the map count determination unit 340 determines the number of maps based on that choice.

[0025] (Risk assessment) The evaluation unit 330 evaluates the "risk level" around each GPS terminal 200 based on the current location information of the GPS terminal 200. The risk level is evaluated by comparing the location of the GPS terminal 200 with a hazard area information table 810 (e.g., busy intersections, bodies of water, places where suspicious persons have been reported in the past) that has been pre-registered, as shown in Figure 8, to determine whether or not the terminal is within a hazard area, and based on the risk level set for that hazard area (e.g., a numerical value from 1 to 5). Real-time incident / accident information, weather information, etc., can also be obtained from external sources and incorporated into the risk level evaluation. In risk assessment, it is desirable that the assessment unit 330 records as a log in the storage device 305 of the information processing device 300, associated with the GPS terminal ID and timestamp, the result of matching the GPS terminal's location information with the risk area information table 810 (e.g., which risk area ID it corresponds to or does not correspond to), the referenced risk level, and, if external information (weather, incident information, etc.) is considered, the source and content of that information, as well as the final risk score and risk level determination result calculated by combining these, in order to verify the system's operation and, if necessary, as evidence to support claims of infringement. Furthermore, the risk area information table 810 does not necessarily have to be fixed information, and may be dynamically updated based on real-time suspicious person information and accident occurrence information provided by local governments or police.

[0026] The map count determination unit 340 determines the number of maps to be displayed on the display unit 401 of the monitoring terminal 400 based on the evaluation results from the evaluation unit 330. In this specification, the series of processes by the processor to "perform a predetermined evaluation" and "determine the number of maps based on the evaluation results" is not necessarily limited to a mode in which the system performs all evaluations and decisions completely autonomously. For example, if a user provides input for the selection of a specific display mode (e.g., "list display mode", "focus display mode", "N-split display mode", etc.; see Figure 14) via the user interface of the monitoring terminal 400, the selection information by the user may be considered as part or all of the main input information for the "predetermined evaluation", or the selection itself may be processed as trigger information equivalent to the "evaluation result" that the system should consider, and the map count determination unit 340 may "determine" an appropriate number of maps (for example, one map for "list display mode", multiple maps according to user settings or system specifications for "N-split display mode") based on this, and this mode may also be within the scope of the technical ideas of this disclosure. In this case, the user's explicit mode selection functions as a specific aspect of the system's "evaluation and decision" process, leading to subsequent information transmission by the display information transmission unit 350. In other words, it also includes a process in which the system understands the user's selection intent and ultimately determines and provides a display configuration, including the number of maps, in accordance with that intent. Furthermore, when the map number determination unit 340 "determines the number of maps," as mentioned above, it is a concept that includes not only determining the number of independent map display areas that occupy the entire display screen of the monitoring terminal 400, but also determining whether or not to add multiple partial map areas (for example, inset maps or maps displayed in small windows; including forms such as 1310A and 1310B in Figure 13) to display the area around each monitored GPS terminal 200 in detail at different scales, while keeping the number of main map display areas (base maps) at one, and determining the number of such areas. That is, control that substantially increases or decreases the number of areas of detailed map information displayed on a single base map based on the evaluation results can also be included in "determining the number of maps."For example, if, based on the evaluation results, it is decided to display one base map and three separate inset maps, this can be interpreted as displaying map information with four different viewpoints or levels of detail. In this case, the display information transmission unit 350 transmits information about the single base map and information about the multiple inset maps to be superimposed on it (such as the display position, content, and scale of each inset map) to the monitoring terminal 400.

[0027] (Modification: Dynamic overlay display) In this modified version, the information processing device 300 may transmit information to display multiple detailed map information and status information related to a specific monitoring target as temporary overlay windows on a single base map of the monitoring terminal 400, based on the evaluation results (see new Figure 18). These overlay windows may dynamically change their display content and position, or switch between being displayed and hidden, depending on user operation, the passage of time, or further evaluation results. Even in such cases, if each overlay window can be interpreted as providing substantially independent geographic information or monitoring target information, the information processing device 300 is considered to be displaying information equivalent to substantially multiple "maps".

[0028] For example, if the scale calculated as a result of the scale evaluation is less than or equal to the "first predetermined scale," the map number determination unit 340 decides to increase the number of maps to "multiple."

[0029] Furthermore, if the risk assessment results in any GPS terminal 200 having a risk level of "first predetermined risk level" (for example, a threshold that the monitor judges to require attention, such as risk level 3 or higher), the map number determination unit 340 decides to increase the number of maps to "multiple".

[0030] Furthermore, if both conditions are met—that the scale is less than or equal to the "first predetermined scale" and that the risk level of at least one GPS terminal 200 is equal to or greater than the "first predetermined risk level"—the map number determination unit 340 increases the number of maps to "multiple."

[0031] On the other hand, even if the scale falls below the "first predetermined scale," if the risk level of all GPS terminals 200 is below the "third predetermined risk level" (for example, a level considered extremely safe, such as inside one's home or on school grounds), the map number determination unit 340 maintains the number of maps at "single."

[0032] The display information transmission unit 350 transmits information (map data, location information of each GPS terminal, display layout instructions, etc.) to the monitoring terminal 400 via the communication unit 310, which is necessary to display the number of maps determined by the map number determination unit 340 on the display unit 401 of the monitoring terminal 400.

[0033] If it is decided to increase the number of maps to "multiple", the display information transmission unit 350 transmits information to display the surrounding conditions of the corresponding GPS terminal 200 in each reconfigured independent map display area at a "second predetermined scale" (e.g., 1 / 2500, a scale more detailed than the "first predetermined scale") that allows for the identification of detailed geographic information (e.g., street address level, individual buildings can be identified).

[0034] If there are three or more GPS terminals 200 to be monitored, and it is decided to increase the number of maps to multiple, the display information transmission unit 350 may transmit information to set the display size of the independent map display area corresponding to the GPS terminal 200 with a relatively high risk level to be larger than the display size of the independent map display area corresponding to the GPS terminal 200 with a relatively low risk level, based on the risk level of each evaluated GPS terminal 200. The specific determination of this display size can be made, for example, using a table based on the risk ranking described above. This allows the monitor to intuitively identify the target that requires the most attention. Figure 10 shows an example of such a display.

[0035] (Variation: Various means of emphasis) Means of highlighting information corresponding to GPS terminals with a relatively higher risk level are not limited to increasing the display size of the independent map display area (see Figure 19). For example, any means of visual or auditory differentiation that can attract the observer's attention, such as changing the color, thickness, or style (e.g., dashed line, blinking) of the border of the area, changing the background color, overlaying a dedicated warning icon, changing the font size or color of related text information (such as the name of the monitored device), or combining it with audio notifications, may also be included in the technical ideas of this disclosure. The important thing is that the information is presented in a way that makes the difference in risk levels easily identifiable by the observer.

[0036] Furthermore, if there are three or more GPS terminals 200 to be monitored and it is decided to increase the number of maps to multiple, the display information transmission unit 350 may identify multiple GPS terminals 200 whose positions are within a predetermined distance range (e.g., within a radius of 50m) as the same group, and transmit information to display the location information of multiple GPS terminals 200 belonging to that same group together in a single independent map display area. This avoids cluttering the screen. Figure 11 shows an example of such grouping display. In addition, when the distance between GPS terminals falls below a first threshold, the display of the map corresponding to one GPS terminal may be temporarily integrated (for example, one map is hidden and the other map is enlarged to display both terminal markers), and then, when the distance exceeds a second threshold greater than the first threshold, the maps of each terminal are separated and displayed again. This allows for a hysteresis effect that prevents frequent display switching near the threshold.

[0037] (Example: Advanced grouping conditions) The criteria for grouping GPS devices are not limited to simple horizontal distance. For example, grouping may be based on three-dimensional distance considering altitude information obtainable by GPS devices, whether or not they are located in the same building by referring to building polygon information included in map information, or on semantic relationships such as whether multiple monitored devices are participating in the same event (e.g., same school, same extracurricular activity) by linking with calendar information and facility information. These advanced grouping criteria are also consistent with the purpose of this disclosure, which is to efficiently manage and display multiple monitored devices.

[0038] Furthermore, layout information may be transmitted to display multiple independent map display areas by dividing the display screen of the monitoring terminal 400 vertically (see Figure 9A), horizontally (see Figure 9B), or in a grid pattern (see Figure 9C).

[0039] Figure 4 is a flowchart showing the main processing flow of the information processing device 300 in this embodiment. This flowchart also shows an example of a map display method performed by the information processing device 300.

[0040] First, the location information receiving unit 320 of the information processing device 300 receives location information that is periodically transmitted from multiple GPS terminals 200 (step S401). This step is achieved by the program being executed by the CPU 301. Next, it is determined whether or not a map display request has been made from the monitoring terminal 400 (step S402). If there is no display request (NO in S402), the process returns to S401.

[0041] If a display request is made (YES in S402), the evaluation unit 330 performs the aforementioned "predetermined evaluation" (including scale evaluation, risk level evaluation, and other evaluations) using a predefined algorithm or machine learning model, etc., based on the latest received location information and / or the current display state (including display context information) received from the monitoring terminal, as well as various information stored in the storage device 305 (static parameters, hazard area information, past logs, etc.) (step S403). This evaluation process is also realized by the execution of a program by the CPU 301.

[0042] (Supplementary information regarding the observability and logging of the evaluation process) In the "predetermined evaluation" process performed by the evaluation unit 330 of this information processing device, it is desirable to record information as log data in the storage device 305 as appropriate, for the purpose of increasing the transparency and verifiability of the decision leading to the final determination of the number of maps, and for the purpose of making it easier to objectively demonstrate that an evaluation included in the scope of rights disclosed in this application is being performed as needed, including the types of main input data used in the evaluation (e.g., an index showing the geographical dispersion of GPS location information, the presence or absence and main content of display context information received from the monitoring terminal, the record ID of the referenced hazard area information table, the value of the applied static importance parameter, etc.), important intermediate indicators generated internally by the evaluation logic (e.g., the calculated assumed scale, the evaluated hazard score, the recommendation score for a specific display mode by the machine learning model, etc.), and an overview of how they contributed to the map number determination logic (e.g., which conditional branch was affected, and with what weight was it considered, etc.). These log data not only contribute to verifying the normal operation and performance evaluation of the system, but can also be used as an aid in determining whether the system is operating within the scope of the technical concept of this disclosure in the event of suspected infringement of rights, and as objective evidence in expert opinions, etc. Furthermore, during the system development phase and maintenance, providing a debug interface and management functions that allow easy external access and analysis of these internal indicators and log information is also effective from the perspective of ensuring system reliability and accelerating problem resolution.

[0043] Next, the map count determination unit 340 determines the number of maps to be displayed on the monitoring terminal 400 (or the number of geographic information areas to be displayed with substantially different viewpoints or levels of detail) based on the evaluation result of S403 (step S404). At this time, for example, conditional branching or more complex decision logic is executed as a program.

[0044] Finally, the display information transmission unit 350 generates information (map data, location information for each GPS terminal, display layout instructions, highlighting instructions, inset map information, etc.) for displaying the number of maps determined in S404 (including control as described in claims 4, 7, 8, 9, and 11 if there are multiple maps) on the monitoring terminal 400, and transmits it via the communication unit 310 (step S405). This information generation and transmission process is also controlled by the program. After that, the process ends (or returns to the standby state).

[0045] The monitoring terminal 400 displays a map on its display unit 401 based on information received from the information processing device 300. Figure 5A is an example screen showing a state where multiple GPS terminals 200A and 200B have their location markers 511A and 511B displayed in a single map display area 510. From this state, for example, if GPS terminals 200A and 200B are geographically separated and the scale evaluation determines that the distance is below the "first predetermined scale", the number of maps is determined to be two, as shown in Figure 5B, and the screen is divided into two independent map display areas 520A and 520B. Map display area 520A displays a detailed map of the area around GPS terminal 200A at the "second predetermined scale", and map display area 520B displays a similarly detailed map of the area around GPS terminal 200B.

[0046] In the specification, "predetermined evaluation" is a higher-level concept. Supporting concepts include "evaluation of the geographical location of the GPS terminal," "evaluation of the security of the GPS terminal," and "evaluation of the intentions and concerns of the observer." Further lower-level concepts include "evaluation of the scale when multiple GPS terminals are displayed on a single map," "evaluation of the degree of danger around each GPS terminal," "evaluation of the distance between GPS terminals," "evaluation based on static importance parameters stored in the information processing device," "evaluation of display mode selection information from the user via the monitoring terminal," and "analysis and evaluation of accumulated past location information history."

[0047] Similarly, "determining the number of maps" is a higher-level concept, while intermediate-level concepts include "deciding whether to display one or multiple maps," and lower-level concepts include "deciding to increase to multiple maps when the scale is less than or equal to a first predetermined scale," "deciding to increase to multiple maps when the level of danger is greater than or equal to a first predetermined danger level," "deciding to include a single base map display area and multiple inset map display areas superimposed on it," and determining the number of actual geographic information areas in the various display modes described above.

[0048] (Combinations of elements in each embodiment) The components disclosed in each of the above embodiments can be combined as appropriate to the extent that they do not contradict each other. For example, one possible combination is to determine the number of maps by combining scale evaluation and risk evaluation, and if there are multiple maps, to adjust the display size according to the risk level, and further to group adjacent maps. In addition, each embodiment and modification disclosed herein can be combined as appropriate, some parts omitted, or replaced with other elements or steps, without departing from the spirit thereof.

[0049] (Variation: Evaluation based on static information on the server side) In the above embodiment, an example was mainly described in which the evaluation unit 330 considers at least one of the location information of the GPS terminal and the current display state of the monitoring terminal, but it is not limited to this. For example, the evaluation unit 330 considers the location information received from each GPS terminal and static importance parameters associated with each GPS terminal that are pre-stored in the storage device 305 of the information processing device 300 (e.g., priority of monitored targets set by the user, default attention levels according to age and health status, deviation risk indicators statistically derived from past behavior patterns, etc.) (The term "static importance parameters" here is distinct from dynamic parameters that are calculated and change in real time each time an evaluation is performed according to the location information transmitted in real time from the GPS terminal or the display state of the monitoring terminal at that time. That is, they are either set in advance by the user or analyzed and set by the system based on relatively long-term data such as past behavior history, and are individual This refers to parameters that are referenced as fixed values ​​in each evaluation session. For example, even if the parameter itself is updated periodically over several hours, days, or weeks by batch processing, or if it is a deviation risk indicator that is reviewed by statistical analysis based on past log data, it is included in the category of "static importance parameters" in this disclosure as long as it is treated as a predetermined value when used as input for individual real-time evaluation processes. This is intended to ensure a certain level of stability and predictability of the evaluation logic while also allowing for the optimization and adaptability of parameters from a medium- to long-term perspective. The number of maps and their respective display modes (scale, size, etc.) may be determined based solely on the "predetermined evaluation". These "static importance parameters" are information managed on the information processing device side independently of the display state of the monitoring terminal at any given time. With this configuration, there is an advantage in that it is possible to achieve optimal map display according to the unique characteristics of each monitored target and the pre-set importance without directly using the dynamic "current display state" on the monitoring terminal side as evaluation input.

[0050] (Variation: Detailed display of multiple objects using inset maps) In the above embodiment, an example in which the screen of the monitoring terminal is divided into multiple independent areas for display when the number of maps is determined to be multiple (see Figures 5B, 9A to 9C) has been mainly described, but the invention is not limited to this. For example, if the map number determination unit 340 evaluates that detailed information of multiple monitoring targets should be provided simultaneously (i.e., it determines that there are essentially multiple maps), the display information transmission unit 350 may transmit information to the monitoring terminal 400 to overlay multiple inset maps (maps displayed in small windows, see 1310A and 1310B in Figure 13) or similar additional detailed map display areas (for example, pop-up windows and overlay displays mentioned above, referring to any partial map display area, not limited to the form of traditional inset maps) that display the surrounding conditions of each monitoring target GPS terminal 200 at a detailed scale (for example, the second predetermined scale) on the main single map display area (hereinafter referred to as the "base map," corresponding to 510 in Figure 5A). In this case, the base map is displayed at a scale that allows for an overview of the entire situation (for example, a wide-area display close to the first predetermined scale), while each inset map displays a magnified view of the vicinity of the corresponding monitored object. The display position, size, scale, etc., of each inset map can be individually determined based on the evaluation results. This configuration has the advantage that the monitor can simultaneously view detailed information on multiple specific objects without losing the overall geographical context.

[0051] (Variation: A configuration primarily based on user-selected display mode switching) The above embodiment mainly describes an example in which the system automatically evaluates the location information and display state of a GPS terminal and actively changes the map display mode based on that evaluation. However, the scope of application of this disclosure is not limited to this. For example, the display unit 401 of the monitoring terminal 400 may always or as needed display multiple display mode selection means (e.g., "list display mode button", "focused mode button", "two-screen split mode button", "four-screen split mode button", etc.; see Figure 14) for the user to directly select a desired display mode. When the user operates any of the display mode selection means, the monitoring terminal 400 transmits the selection information to the information processing device 300. The evaluation unit 330 or the map number determination unit 340 of the information processing device 300 treats the display mode selection information received from the user as the main "evaluation information" or "evaluation result itself", and determines the optimal "number of maps" corresponding to the selected display mode. For example, if "list display mode" is selected, the number of maps is determined to be 1, and if "two-screen split mode" is selected, the number of maps is determined to be 2. Based on the number of maps determined in this way, the display information transmission unit 350 optimizes the specific display content (target assignment, scale, etc.) of each display area (one or more) by taking into account the latest location information of each GPS terminal and, if applicable, other circumstances (such as the degree of danger), and transmits the information for this purpose to the monitoring terminal 400. The monitoring terminal 400 displays the map according to the received information. With this configuration, the user can proactively switch the display mode according to their own intentions and judgment of the situation, and the system respects the user's choice while providing optimal information within the framework of the selected mode. In this case as well, the system determines the final number of maps and display configuration and transmits the information based on the evaluation trigger of the user's choice, and this is included in the basic framework of this disclosure.

[0052] (Variation: Proposed map display based on analysis of past activity logs) The above embodiment describes an example in which the map display mode is dynamically determined mainly based on real-time or near-real-time location information and immediately displayed on the monitoring terminal, but the scope of application of this disclosure is not limited thereto. The evaluation unit 330 of the information processing device 300 may primarily analyze the location information history of one or more GPS terminals 200 over a long period of time (e.g., several hours ago, the previous day, or several weeks ago) stored in the storage device 305. This analysis may be performed as a periodic batch process during times when the system load is low, such as at night, or it may be performed on demand in response to explicit instructions from the user of the monitoring terminal 400, such as a "request for behavioral analysis report" or "confirmation of past behaviors of concern." The evaluation unit 330 identifies "locations requiring attention" or "notable behavioral patterns" through this past log analysis. These include locations where a particular monitored subject exhibited unusual behavioral patterns (e.g., frequent travel on routes not normally used, unusually long stays in specific areas), periods and patterns of frequent approaches to dangerous areas in the past, or events where multiple monitored subjects exhibited unique aggregation / dispersion patterns at specific points in the past or over specific periods. The map count determination unit 340 determines the optimal "number of maps" and their respective display contents (period to be displayed, scale of the target maps, presence and method of highlighting, etc.) to present these identified "locations requiring attention," related time periods, or behavioral patterns revealed by the analysis to the user in an easily understandable manner. For example, regarding a particular deviant behavior of a monitored subject, it can be determined to display three maps that are temporally or geographically linked, such as a map of the point where the deviation began, a map of the main points along the way during the deviation, and a map of the final destination. Alternatively, it may be decided to display multiple maps organized by target and time period to show situations where multiple monitored targets approached a specific area at different times. Based on these decisions, the display information transmission unit 350 sends a summary of the past log analysis results to the monitoring terminal 400 (e.g., "Last Monday, when leaving school, student A traveled a different route than usual for 30 minutes. Would you like to check the details?").(See Figure 15) Along with this, information prompting the user to review relevant past situations on a predetermined number and content of maps is transmitted, or detailed map information is sent to display those maps according to the user's selection. With this configuration, in addition to real-time monitoring, it becomes possible to systematically review past behavior to discover signs of potential risks that may not immediately become apparent, and to gain deeper insights into the behavioral tendencies and lifestyle patterns of the monitored person, thereby realizing more comprehensive monitoring support.

[0053] This disclosure contributes to improving the functionality of the computer (information processing device 300 and monitoring terminal 400) and the user interface (UI).

[0054] (Improvements to computer functionality) Reduced processing load (reduced cognitive load on monitors): By automating the complex screen operations (zooming in / out, switching targets) previously performed manually by monitors to understand the status of multiple monitored objects, and by providing the optimal map display (number of maps, scale, layout) according to the situation, the cognitive load on monitors is significantly reduced. This improves the processing efficiency of computers in monitoring tasks (overall efficiency including human processes).

[0055] Improved real-time data processing and display (real-time situational awareness): The system automatically detects dangerous situations and changes in situations requiring attention (risk of information loss due to wide-area coverage, entry into dangerous areas) and immediately switches to the most optimal detailed display, thereby improving real-time situational awareness by the monitor.

[0056] (Improved User Interface) Improved Usability: Reduced Operational Burden: Even with multiple monitored targets, the system automatically provides an easy-to-understand map display, eliminating the need for frequent manual operation by the monitor and improving usability. Usability is significantly improved, especially when monitoring while doing other tasks.

[0057] Improved visibility: By preventing a reduction in information due to wide-area display on a single map and simultaneously displaying detailed maps of each target at an appropriate scale when necessary, the visibility of the situation of individual targets is improved. Adjusting the display size according to the level of danger, grouping displays, and organized divided layouts also contribute to improved visibility.

[0058] Prevention of operational errors: Reducing complex manual operations lowers the chances of operational errors.

[0059] Improved accessibility: Enhanced visibility and reduced operational burden can lead to improved accessibility, for example, by making information more accessible to users with visual impairments or those who have difficulty with fine screen operations.
