Summary of the Invention

Problems to be Solved by the Invention

[0004] However, there has been room for improvement in the conventional system. One of the objects of the present disclosure is to improve privacy protection when a monitored person sends a message to a specific monitor, and the intuitiveness, ease, and reliability of the message transmission operation in a monitored person terminal having a limited interface.

Means for Solving the Problems

[0007] Embodiments of this disclosure will be described in detail below with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and redundant explanations are omitted as appropriate.

[0008] Conventional GPS-based monitoring systems had a problem: if multiple guardians (e.g., mother, father, grandparents, etc.) were registered as guardians, a message sent from the child's GPS device to a specific guardian would be uniformly notified to all registered guardians' devices. This made it difficult for children to send private messages that they only wanted to convey to a specific person, or messages they didn't want other family members to hear.

[0009] Furthermore, GPS terminals generally have limited screen size and input interfaces, resulting in a lack of mechanisms that allow children to intuitively select message recipients and send messages without making mistakes. In particular, for young elementary school children who are not yet proficient in reading and writing, conventional methods of selecting recipients, which involve list displays and multiple button operations, can be cognitively burdensome and may hinder the rapid transmission of information in emergencies. This embodiment can solve these problems.

[0010] 1. Overview of the entire system Figure 1 shows an example of the configuration of the monitoring system 1 according to this embodiment. The monitoring system 1 includes, for example, monitored terminals 40a and 40b (also called GPS terminals) held by the person being monitored (target person), such as a child or the elderly, a monitoring terminal 30 (also called a parent terminal) used by a supervisor, such as a guardian, and a server 20. These are connected to each other so as to be able to communicate with one another via a network 10 (for example, the internet or a mobile phone network).

[0011] Each monitored terminal 40a and 40b has a GPS function (GPS sensor 40H) and periodically acquires location information indicating its current location and transmits it to the server 20 via the network 10. Furthermore, each monitored terminal 40a and 40b includes an input unit 40C that receives message transmission instructions and a display unit 40D that displays visual information (face image, portrait, etc.) of a person who can be identified as the target of the message transmission from among multiple monitors. Details of the monitored terminals will be explained later with reference to Figure 6.

[0012] The input unit 40C of the monitored terminal 40 is not limited to physical buttons or touch sensors, but can also function as a means of receiving message transmission instructions by detecting the physical behavior of the terminal (e.g., a specific tilt, a specific vibration pattern, a specific way of shaking) acquired from an accelerometer, gyroscope, or other motion sensor mounted on the terminal. In this case, the detected terminal behavior is treated as one of the "multiple operation patterns" in this disclosure. This makes it possible for the monitored person to intuitively send a message transmission instruction even when both hands are occupied or when visual confirmation is difficult, thereby increasing the reliability of information transmission in emergencies.

[0013] Furthermore, in addition to receiving a message transmission instruction through a direct operation of the monitored person on the monitored person terminal 40 (such as pressing a physical button, touching, voice command, body movement, etc.), the input unit 40C of the monitored person terminal 40 can also function as a means for detecting a specific situation change of the monitored person based on information from environmental sensors (e.g., temperature sensor, humidity sensor, fall sensor, light sensor, heart rate sensor, etc.) mounted on the terminal or from an external sensor network (e.g., smart home sensor), and receiving this as a "message transmission instruction". In this case, the detected situation change (e.g., high temperature abnormality, fall, heart rate abnormality) is treated as a type of "message transmission instruction" in the present disclosure, and becomes a trigger for automatically transmitting a message suitable for the situation (e.g., "Suspected heatstroke", "Fell down"). Thereby, even in a situation where the monitored person himself / herself cannot perform an operation, prompt and appropriate information can be transmitted to the monitor, and the certainty of emergency response can be further enhanced. The "input unit that receives a message transmission instruction" in the present disclosure includes not only a direct intention expression of the monitored person, but also a function of detecting such a situation change of the monitored person and serving as a trigger for message transmission.

[0014] The server 20 includes a communication unit 20A (reception unit 201) that receives position information transmitted from a plurality of monitored person terminals. Further, it includes a display control information determination unit 204 that identifies a main monitor for message transmission from the monitored person terminal based on a predetermined criterion (such as schedule information, proximity information based on position information, risk level information, etc.) among a plurality of monitors. It includes a communication unit 20A (transmission unit 202) that transmits information regarding the identified main monitor and information regarding other monitors to the monitored person terminal. Furthermore, it includes a communication unit 20A (reception unit 201) that receives message data and transmission destination identification information for identifying the transmission destination of the message from the monitored person terminal, and a communication unit 20A (transmission unit 202) that transmits the message data only to the monitor terminal 30 corresponding to the received transmission destination identification information based on the received transmission destination identification information. The details of the server will be described by referring to FIGS. 2 and 3 described later.

[0015] The monitoring terminal 30 is equipped with a display unit 30D that receives information from the server 20 and displays a map. The monitoring terminal 30 is, for example, a smartphone, tablet, or PC, and has dedicated application software installed. Based on the information received from the server 20, the monitoring terminal 30 displays a map and receives messages on its own display unit. Details of the monitoring terminal will be explained later with reference to Figures 4 and 5.

[0016] In this system, the server 20 identifies the main monitor based on a predetermined criterion and transmits the visual information and other monitor information of that person to the monitored terminal 40. On the display unit 40D of the monitored terminal 40, the visual information of the main monitor is displayed based on the received information. In the input unit 40C of the monitored terminal 40, a plurality of operation patterns with different operation difficulties (e.g., single click, double click, simultaneous pressing of multiple buttons, specific tilt pattern, specific vibration pattern) are provided. Specifically, for sending a message to the main monitor, who is the person the user wants to contact most frequently, the simplest operation pattern such as a single click that the monitored person can operate reflexively and intuitively, or a specific tilt pattern or a short-time vibration pattern is assigned. This enables even a young child to quickly send a message without hesitation, especially in an emergency. On the other hand, for switching to or sending a message to other monitors other than the main monitor, a "slightly difficult operation pattern" that requires a more intentional operation such as a double click, long press, or simultaneous pressing of multiple buttons, or a more complex tilt pattern or continuous vibration pattern is assigned. This difference in operation difficulty reduces the risk of mistransmission and provides a time buffer for the monitored person to consciously confirm "who am I about to send a message to", which is extremely important for improving privacy protection and psychological comfort. When a specific operation pattern (e.g., single click, or specific tilt pattern) is detected, the message data corresponding to the main monitor displayed on the display unit 40D is transmitted to the server 20. When other operation patterns (e.g., double click, or different tilt pattern) are detected, the visual information of the person displayed on the display unit 40D is switched to another monitor other than the main one, and the message data corresponding to the switched person is transmitted to the server 20. The server 20 routes the message only to a specific monitor terminal 30 based on the transmission destination identification information of the received message.

[0017] In this embodiment, the "input unit" is not limited to physical buttons or touch sensors, but may include any means that accept message transmission instructions from the monitored person, such as a voice recognition unit or gesture recognition unit. Furthermore, the "display unit" is not limited to a display that shows visual information such as a person's facial image, but may include non-visual information presentation means that can identify a person, such as LED flashing patterns, vibration patterns, or specific sound patterns. The core technical challenge of this disclosure, "improving the intuitiveness, ease, and reliability of message transmission to a specific monitored person," is achieved by combining visual information from the display unit with differences in difficulty due to operation patterns. However, its essence lies in a mechanism that allows the monitored person to quickly and accurately select the intended recipient and send a message on a monitored terminal with a limited interface. Therefore, a system that achieves the same objective by combining specific voice patterns or voice guidance in addition to, or as an alternative to, visual information about a person may also be included within the scope of the technical concept of this disclosure. For example, a configuration in which a specific person's name is recognized by voice recognition and a decision is made to send a message to that person is also conceivable.

[0018] Furthermore, the aforementioned multiple operation patterns are not necessarily used solely for the purpose of directly switching the human visual information displayed on the display unit 40D. For example, it is also possible to configure the system to cyclically select a specific destination from among multiple transmission candidates by performing a series of operations (e.g., pressing the button multiple times in succession) on a single physical button or a multi-function button (input unit 40C). In this case, the selected destination may be presented to the monitored person by a simple display on the display unit 40D (e.g., number, icon, number of flashes) or by voice guidance (e.g., "Mom has been selected"). Such a configuration also achieves the objective of this disclosure, which is to intuitively select multiple destinations within a limited interface and send messages without errors.

[0019] Furthermore, the display unit 40D of the monitored terminal 40 may be configured to simultaneously display visual information of multiple monitors. In this case, the monitored person can directly select a specific destination from among multiple monitors in response to operation instructions from the input unit 40C (e.g., touch operation, cursor movement). At this time, the switching control unit can also assist the monitored person in selecting the desired destination more easily and intuitively by controlling the display order, size, brightness, blinking pattern, or presence or absence of highlighting of the multiple visual information of the displayed persons based on information received from the server 20 (e.g., past message transmission history, a favorites list set by the monitored person, or information on monitors who are frequently contacted based on the monitored person's behavior patterns). This makes it possible to achieve the "improvement of intuition, ease of use, and reliability" that is the objective of this disclosure.

[0020] The "transmitting unit for sending messages" in this embodiment is not limited to a configuration that directly transfers message data from a monitored terminal to a specific monitoring terminal. For example, it may also include a function that uploads or updates message data (e.g., pre-written messages, voice message files) from a monitored terminal to a shared cloud storage or common data management server accessible to the monitoring terminal. In this case, the monitoring terminal receives the message data by periodically checking the shared storage or by receiving update notifications from the shared storage. Even such indirect information sharing is included in the technical concept of this disclosure, which is to "send" a message from a monitored person to a specific monitoring person to ensure reliable information transmission and rapid information sharing.

[0021] 2. Explanation of the Configuration Block Diagram (Hardware Configuration Diagram, etc.) (server) Figure 2 is a block diagram showing an example of the hardware configuration of server 20. Server 20 is configured as a general computer system, comprising a CPU (Central Processing Unit) 20C, main memory (RAM (Random Access Memory) and ROM (Read Only Memory) (not shown), auxiliary storage (storage device 20B, e.g., HDD or SSD), and a communication interface (IF) 20A for communicating with other devices (monitoring terminal 30, monitored terminal 40, etc.) via network 10. Storage device 20B stores the OS (Operating System), programs for realizing various functions described later, and data necessary for processing (user information, monitored terminal information, location history, risk level information, schedule information, facility information, map data, monitor person visual information, etc.). The CPU 20C controls the operation of the entire server 20 by reading and executing programs from storage device 20B.

[0022] (Surveillance terminal) Figure 4 is a block diagram showing an example of the hardware configuration of the monitoring terminal 30. The monitoring terminal 30 comprises a CPU 30E, a main memory (RAM, ROM, etc., not shown), an auxiliary memory device 30B (e.g., flash memory), a communication IF 30A for communicating with the server 20 etc. via the network 10, an input device 30C (e.g., touch panel, buttons) for receiving instructions from the user, and a display device 30D (e.g., liquid crystal display, organic EL display) for displaying maps and various information. In this embodiment, a microphone 30F and a speaker 30G for audio input and output may also be provided. The memory device 30B stores the OS, application programs for realizing functions such as message reception and map display, and data necessary for processing. The CPU 30E controls the operation of the entire monitoring terminal 30 by executing programs.

[0023] (Monitored user terminal) Figure 6 is a block diagram showing an example of the hardware configuration of the monitored terminal 40 (40a, 40b). The monitored terminal 40 includes a CPU 40E, a main memory (RAM, ROM, etc., not shown), an auxiliary memory device 40B (e.g., flash memory), a communication IF 40A for communicating with the server 20 etc. via the network 10, and a GPS sensor 40H for determining its own position by receiving signals from GPS satellites. In this embodiment, a simple display device 40D (e.g., LED, small display) for notifying the user, etc., a microphone 40F, speaker 40G for audio input / output, and an input device 40C (e.g., physical button, touch sensor) for operation may also be included. The memory device 40B stores firmware and programs for controlling the operation of the monitored terminal 40. The CPU 40E controls the operation of the entire monitored terminal 40 by executing the firmware and programs, and periodically transmits the position information acquired by the GPS sensor 40H to the server 20 via the communication IF 40A. Furthermore, the CPU 40E receives a message transmission instruction from the input device 40C, displays the visual information of multiple observers on the display device 40D, and performs the process of sending a message according to a specific operation pattern, as well as the process of switching the visual information of the observers.

[0024] 3. Explanation of the Functional Block Diagram (server) Figure 3 is a block diagram showing an example of the functional configuration of server 20. Server 20 functions primarily as a receiving unit 201, a transmitting unit 202, a storage device control unit 203, a display control information determination unit 204, a location information management unit 205, and a related information management unit 206, with the CPU 20C executing a program stored in the storage device 20B.

[0025] The receiving unit 201 receives location information, message data, destination identification information, etc. from monitored terminals 40a and 40b via the communication IF 20A, and also receives map display requests and various setting information from the monitoring terminal 30.

[0026] The transmitting unit 202 transmits information about the main monitor determined by the display control information determination unit 204, information about other monitors, message data, and related information such as the display size and scale of the map to the monitored terminal 40 and the monitoring terminal 30 via the communication IF 20A.

[0027] The storage device control unit 203 controls the reading and writing of data to the storage device 20B.

[0028] The display control information determination unit 204 is the core functional unit of this embodiment and performs control to identify the main monitor in message transmission from the monitored terminal 40. Specifically, it determines the visual information of the main monitor to be displayed on the monitored terminal 40 based on location information stored in the storage device 20B and various information managed by the related information management unit 206 (risk level, schedule, facility information, etc.). This determination is made by considering, for example, at least one of the risk level information, schedule information, or proximity information based on location information of the monitored terminal 40.

[0029] "Risk level information" refers to information about the risk level of the area where the monitored terminal is located (risk level score set by the operator, traffic information, suspicious person information, etc.). The display control information determination unit 204 determines that the situation is urgent when the monitored terminal is in a high-risk area and prioritizes setting a specific monitor (e.g., parent representative) as the main monitor.

[0030] "Schedule information" refers to the schedule information (scheduled location, time, route, etc.) of the monitored terminal (child) registered by the user (monitor). The display control information determination unit 204 considers the situation to be equivalent to a predetermined risk level if the monitored terminal deviates from the schedule and automatically switches the main monitor.

[0031] "Proximity information based on location information" refers to information that is determined when a monitor is within a predetermined distance, based on the location information of the monitored terminal and the location information of the monitor terminal. The display control information determination unit 204 sets the monitor closest to the monitored person's current location as the main monitor.

[0032] These criteria can be applied based on priority, for example, with risk information taking top priority, followed by schedule information, and finally proximity information based on location. This ensures that messages reach the most appropriate monitors in high-priority situations.

[0033] In particular, the priority application of risk information in the display control information determination unit 204 is highly effective in emergency response. The server compares the GPS location information of the monitored terminal 40 with the risk area information table 224 stored in the storage device 20B, and if it determines that the monitored person has entered a "risk area," it highly evaluates the urgency. At this time, it forcibly identifies a "specific monitor who has been registered in advance as an emergency contact (e.g., the primary guardian or a guardian with the function of coordinating with the police / emergency services)" as the main monitor and transmits that person's visual information to the monitored terminal 40. As a result, when a child is in a dangerous situation, even in a panic state, a message can be sent to the most appropriate guardian, predetermined by simply pressing the main button once. This contributes to a dramatic improvement in the reliability and responsiveness of emergency response, which is difficult to achieve with conventional systems.

[0034] The location information management unit 205 stores and manages the location information of each monitored terminal 40 received in the storage device 20B (database), associating it with the terminal ID and timestamp.

[0035] The related information management unit 206 manages various related information necessary for the main monitor identification and message routing by the display control information determination unit 204 (for example, dangerous area information set by the operator, schedule information registered by the user, facility information, visual information of each monitor, standard message phrases, etc.) in the storage device 20B.

[0036] (Surveillance terminal) Figure 5 is a block diagram showing an example of the functional configuration of the monitoring terminal 30. The monitoring terminal 30 primarily functions as a receiving unit 301, a transmitting unit 302, a storage device control unit 303, an input receiving unit 304, and a display device control unit 305, with the CPU 30E executing an application program stored in the storage device 30B.

[0037] The receiving unit 301 receives message data, map display size and scale information, and related information transmitted from the server 20 via the communication IF 30A.

[0038] The transmitting unit 302 sends map display requests, user-entered configuration information, and other data to the server 20 via the communication IF 30A.

[0039] The storage device control unit 303 controls the reading and writing of data to the storage device 30B.

[0040] The input reception unit 304 receives instructions from the user (monitor) to display a map, input of various settings, etc., via the input device 30C (touch panel, etc.).

[0041] The display device control unit 305 displays maps and messages on the display device 30D based on the information received by the receiving unit 301 (map data, message data, location information, display size and scale information, etc.).

[0042] (Monitored user terminal) The monitored terminal 40 functions primarily as an input unit 40C, a display unit 40D, a transmission unit (part of the communication IF 40A), and a switching control unit (controlled by the CPU 40E), with the CPU 40E executing a program stored in the storage device 40B.

[0043] Figure 7 is a flowchart showing the flow of the destination selection process on the monitored terminal 40.

[0044] First, the system receives visual information about the main monitor and information about other monitors from the server 20 (S100). This visual information may include, for example, a facial image, a caricature, or an icon symbolizing a family (see Appendix 2). The display unit 40D displays the visual information about the main monitor based on the received information (S110). Figure 9 shows an example of the display screen in this state.

[0045] Here, it is preferable, but not necessarily limited, that the visual information of a person be displayed directly as a facial image or portrait. For example, if the display unit 40D is small and cannot display a facial image, or in a system where voice input is the primary method, the system may be configured to allow the monitored person to intuitively understand who they are trying to message by outputting an abstract icon that can identify each monitored person, a flashing pattern of a specific color, or related sounds (e.g., "Mom's voice," "Dad's voice") for a short time. In this case, even if the displayed information is not visual information of a person, as long as it is information that can identify that person, it may be included in the scope of this disclosure.

[0046] In this embodiment, "visual information of a person" is not limited to images or portraits that directly depict a person's face, but refers to any visual representation that makes the person visually distinguishable and identifiable from other people. For example, an abstract icon assigned to a specific person, a geometric pattern of a specific color, or a character image such as an animal or vehicle is included in the scope of this disclosure as "visual information of a person" as long as it is recognized as associated with the person by the monitored person or the monitor and allows for intuitive identification of the recipient. This is intended to ensure that the essence of the disclosure is not impaired even if the display means is simplified depending on the age, cognitive characteristics, or cost constraints of the monitored person.

[0047] Next, the input unit 40C receives a message transmission instruction (S120). The input unit 40C is provided with multiple operation patterns of varying difficulty (corresponding to Appendix 3). For example, it can include at least one of a single click, a double click, or a long press, or a specific tilt pattern, a specific vibration pattern, or even a specific detection pattern of sensor information indicating the physical state of the monitored person or environmental changes.

[0048] The system determines whether a specific operation pattern (for example, a single click, a specific tilt pattern, or detection of an anomaly in a specific environmental sensor value) has been detected (S130). If a specific operation pattern is detected (S130: Yes), the transmission unit sends message data corresponding to the main monitor displayed on the display unit 40D to the server 20 (S140). Figure 10 shows the screen when this operation is transmitted. At this time, the transmission unit may add information regarding urgency or privacy level to the message to be sent, depending on the type of specific operation pattern (corresponding to Appendix 4).

[0049] If no specific operation pattern is detected (S130: No), the system determines whether another operation pattern (e.g., double-click, or a specific different tilt pattern) has been detected (S150). If another operation pattern is detected (S150), the switching control unit switches the person visual information displayed on the display unit 40D to a different monitor other than the main one (S160). Figure 11 shows the screen at the time of switching. At this time, the switching control unit may display text information of the monitor corresponding to the switched person visual information (e.g., "Dad") for a predetermined time (e.g., 2 seconds) (corresponding to Appendix 7). This display of text information has technical significance in that it significantly reduces erroneous transmissions and improves the reliability of the operation by providing an opportunity for final visual confirmation, considering the possibility that the monitored person may mistakenly identify similar people based on face images alone, or that their attention may be diverted to another point during the switching operation. Figure 12 shows the display screen after switching. Furthermore, the switching control unit can also identify the main monitor by considering at least one of the following: risk level information, schedule information, or proximity information based on location information of the monitored terminal, and control the display of the visual information of the main monitor (corresponding to Appendix 5). In particular, it is desirable to identify the main monitor by prioritizing risk level information over schedule information and proximity information based on location information (corresponding to Appendix 6).

[0050] In addition to the function of switching the visual information of a person displayed in the display unit 40D to a different monitor other than the main monitor, or as an alternative, the switching control unit also has the function of sequentially presenting candidate monitors as recipients in accordance with the monitored person's operation pattern (e.g., pressing a button multiple times in succession). This presentation can be in any form that allows the monitored person to identify the recipient they have selected, including not only visual information (e.g., updating of displayed numbers or icons) but also voice guidance, flashing count, or vibration pattern. This allows the monitored person to recognize the intended recipient through various interfaces without being limited to the limited form of switching visual display content, thereby preventing accidental transmission. The expression "switching visual information of a person to a different monitor" in this disclosure encompasses all such methods of presenting candidate recipients.

[0051] The switching control unit has a function to switch the visual information of a person displayed on the display unit 40D to a different monitor other than the main one, or a function to sequentially present candidate recipients, or as an alternative, a function to visually highlight a monitor that the monitored person should select, or is likely to select, from among multiple visual information of people simultaneously displayed on the display unit 40D. This highlighting can be performed in various forms, such as changing brightness, blinking, adding a border, changing the icon size, or displaying in a different color. This highlighting can be controlled based on "predetermined criteria" such as risk information, schedule information, or proximity information based on location information of the monitored person's terminal, or it can be controlled based on past message transmission history or a favorites list set by the monitored person themselves. The expression "switching the visual information of a person displayed on the display unit to a different monitor" in this disclosure encompasses all such methods of highlighting candidate recipients and assisting selection.

[0052] After the visual information of the person is switched, the transmitting unit may disable message transmission until a predetermined time (for example, a few seconds) has elapsed (corresponding to Appendix 8). This prevents erroneous operation immediately after the switch and gives the monitored person time to reconfirm the recipient. After the predetermined time has elapsed, or in response to input to the voice guidance prompting transmission confirmation (corresponding to Appendix 9), the transmitting unit sends message data corresponding to the switched person to the server 20 (S170). The message to be sent can be a pre-written message or a voice message (corresponding to Appendix 10). Figure 13 shows an example of a voice message recording screen. The transmitting unit may also transmit messages using Low Power Wide Area (LPWA) communication (corresponding to Appendix 11). The use of LPWA communication (for example, LTE-M or NB-IoT) has an important technical effect in that its low power consumption characteristics can significantly extend battery life, especially in small monitored terminals 40. Furthermore, LPWA communication covers a wide area and enables relatively stable communication even in places where conventional cellular networks have difficulty reaching, such as underground or inside buildings. This reduces the risk of battery depletion in emergencies and improves the reliability and stability of communication by allowing messages to be sent regardless of location. While voice messages tend to be larger in data size than text data, LPWA communication is optimized for "intermittent transmission and reception of small amounts of data," enabling efficient transmission of short voice messages. This provides a concrete solution to the technical challenge of reliable voice message transmission in monitoring systems, where low power consumption, wide coverage, and stable communication are simultaneously required. Even if such transmission involves indirect data sharing via shared cloud storage, the characteristics of LPWA communication are effective in enhancing its efficiency and reliability.

[0053] 4. Explanation of the table structure of the data stored in the memory unit. Figure 14 shows an example of the structure of the main data stored in the storage device 20B of the server 20. The configuration examples of each table are described in more detail below.

[0054] The User Information Table 220 is a table that manages information about the monitor (parent). Its main fields include a "User ID" (primary key) that uniquely identifies the user within the system, the user's name, contact information (email address and phone number), "password information" used for login authentication, and a "related monitored terminal ID list" that holds a list of IDs of monitored terminals that the user has registered as monitored targets. It may also include data paths or IDs of personal visual information (face image, portrait, etc.) associated with each monitor, and default urgency settings when sending messages.

[0055] The monitored terminal information table 221 is a table that manages information about monitored terminals (child terminals) that are being monitored. Its main fields include a "Terminal ID" (primary key) that uniquely identifies the terminal, a "Terminal Name" set by the user for easy identification (e.g., child's name), the "Date of Birth" of the person using the terminal (e.g., child), the terminal's current "Battery Level," the "Last Communication Date and Time" indicating the date and time of the last communication with the server, the "Terminal Status" indicating the terminal's operating status, and the "Current Contract Plan" indicating the currently applied service plan. It also includes an "Associated User ID" (foreign key to the User Information Table) that indicates the user who manages this terminal.

[0056] The location information history table 222 is a table that stores location information transmitted chronologically from each monitored terminal. Its main fields include a "history ID" (primary key) that uniquely identifies each history, a "terminal ID" (foreign key to the monitored terminal information table) that indicates the terminal that transmitted the location information, "latitude" and "longitude" that indicate the determined location, and a "positioning time" (timestamp) that indicates the date and time the positioning was performed.

[0057] The parent-child relationship (monitoring relationship) table 223 is a table that manages the relationships between which users have registered which monitored devices as targets for monitoring. This table uses a pair of "User ID" (foreign key to the user information table) and "Device ID" (foreign key to the monitored device information table) as its primary key. If multiple users (e.g., father and mother) monitor the same monitored device, multiple records will be generated.

[0058] The Hazardous Area Information Table 224 is a table that manages information about hazardous areas set by operators and users. Its main fields include "Area ID" (primary key) which uniquely identifies the area, "Area Name" which indicates the name of the area, "Area Definition" which defines the geographical extent of the area (e.g., a list of polygon coordinates), and "Hazard Level" which indicates the degree of danger of the area (e.g., a numerical value from 1 to 10).

[0059] The Schedule Information Table 225 is a table that manages the schedule information of monitored devices (children) registered by the user (supervisor). Its main fields include a "Schedule ID" (primary key) that uniquely identifies the schedule, a "Device ID" (foreign key to the monitored device information table) that indicates the target device, an "Appointment" (e.g., tutoring, extracurricular activity) that indicates the content of the schedule, a "Location" (foreign key to the facility information table or address string) that indicates the location where the appointment is scheduled, and the "Start Time" and "End Time" of the appointment.

[0060] 5. Explanation of the processing flow Figure 8 is a sequence diagram showing the flow of the main message transmission process in the monitoring system 1.

[0061] First, the monitored terminal 40 periodically determines its own location and transmits it to the server 20 (S200: Location information transmission). The server 20 stores the received location information in a database (location information history table 222, etc.) (S210: Location information storage).

[0062] The display control information determination unit 204 of the server 20 identifies the main monitor to be displayed on the monitored terminal 40 based on the location information of the monitored terminal 40, related information (danger area information table 224, schedule information table 225, etc.), and monitor information (user information table 220, etc.), and generates display control information including the visual information of that person (S220: display control information generation).

[0063] Server 20 sends the generated display control information to the monitored terminal 40 (S230: Display control information transmission).

[0064] The display unit 40D of the monitored terminal 40 displays the visual information of the main monitor and information about other monitors (e.g., for display during switching) based on the received display control information (S240: Display of visual information of the monitor).

[0065] When the monitored user performs a message transmission operation on the monitored user terminal 40, the input unit 40C receives the message transmission instruction (S250: Message transmission instruction received). At this time, multiple operation patterns with different difficulty levels are detected (S250).

[0066] The switching control unit of the monitored terminal 40 determines whether or not to switch the displayed person visual information according to the type of message transmission instruction (operation pattern) (S260: destination switching determination). If switching is to be done (S260: Yes), the person visual information on the display unit 40D is switched (S270: person visual information switching). Subsequently, the monitored terminal 40 generates message data to which the monitor corresponding to the displayed person visual information is the destination (S280: message data generation).

[0067] The generated message data (including recipient identification information) is sent from the transmission unit of the monitored terminal 40 to the server 20 (S290: Message data transmission).

[0068] Server 20 identifies the monitor terminal 30 to which the message will be sent based on the destination identification information contained in the received message data, and routes the message data (S300: Message routing).

[0069] The monitoring terminal 30 receives message data routed from the server 20 (S310: message received) and displays the message on the display unit 30D (S320: message displayed).

[0070] 6. Contributes to improvements in computer functionality and user interface. The monitoring system according to this embodiment improves the functions and user interface of the computer (monitored user terminal 40, server 20, monitoring terminal 30).

[0071] Specifically, by providing a mechanism that allows monitored individuals to send messages only to specific monitors, which was difficult with conventional systems due to the limited interface of the monitored terminal, this enhances the privacy protection and psychological security of monitored individuals. This goes beyond simply improving the efficiency of information transmission and contributes to a qualitative improvement as a computer system that takes into account the psychological aspects of the user.

[0072] Furthermore, by combining the display of visual information about individuals (such as facial images) with differences in the difficulty of operation (easy operation / slightly difficult operation), even young elementary school children who are unfamiliar with reading and writing can quickly send messages to their intended recipients without confusion. This contributes to improving usability on the monitored terminal. In particular, the measures to prevent accidental operation (such as displaying text information when switching, delaying the activation of sending, and confirmation by voice guidance) are human interface designs optimized for the cognitive characteristics of the target user, and by ensuring rapid and reliable information transmission in emergencies, they enhance the reliability and responsiveness of the entire system.

[0073] Furthermore, the automatic switching of the main monitor based on schedule settings and location information (proximity) reduces the processing load on the display control information determination unit 204 of the server 20, eliminating the need for monitors to constantly adjust settings manually, thereby making the monitoring system more flexible and efficient. This also reduces the management load on the system side, enabling smoother operation. In addition, reducing erroneous transmissions reduces unnecessary communication processing and server load, ultimately contributing to the overall resource efficiency of the system (reduced processing load, reduced number of communications and communication volume). The use of LPWA communication contributes to suppressing battery consumption of the monitored terminal, which has technical significance in improving the overall operational efficiency and continued usability of the system.

[0074] 7. Combining elements of each embodiment as appropriate. The components of each of the above embodiments and examples can be combined as appropriate, within the bounds of consistency.
