Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in such small displays, when a user physically presses the display for an operation, the display surface, especially the central part, may be widely covered by the finger or palm used for the operation. For this reason, important information such as the remaining callable time, battery level, and emergency messages displayed in the central part of the display may be hidden, resulting in the possibility that the user may miss it or not be able to grasp it instantaneously. In particular, in the case of a GPS terminal for children that has been extremely miniaturized for improved portability, a delay in information grasping in an emergency can pose a serious risk directly related to the safety of children.

[0006] ​The technology disclosed herein aims to reduce the possibility that users may not be able to smoothly grasp the necessary information when operating the display on terminals equipped with small displays. [Means for solving the problem]

[0009] Hereinafter, one embodiment of the technology described herein will be described in detail with reference to the drawings. This embodiment is illustrative to facilitate understanding of the technology described herein, and the technology is not limited to this embodiment. Elements of each embodiment may be combined as appropriate.

[0010] 1. Overall configuration of the device Figure 1 shows the overall configuration of the GPS monitoring system according to this embodiment. This system mainly consists of a GPS terminal 100, a monitoring terminal 300, and a server 400 that mediates information transmission between them.

[0011] The GPS terminal 100 is a small device carried by the child that transmits location information, emergency signals, messages, and voice messages to the server 400, and also receives information from the monitoring terminal 300 (messages, voice messages, setting changes, etc.) via the server 400. The monitoring terminal 300 (sometimes referred to as the "external setting terminal 230") is a smartphone or tablet used by a parent or guardian, and can check the location information of the GPS terminal 100 via the server 400, send messages to the GPS terminal 100, and make calls. Specifically, the monitoring terminal 300 has a dedicated application installed to link with the GPS terminal 100, and through this application it provides functions to display the current location and movement history of the GPS terminal 100 on a map in real time, to send and receive voice calls and text messages with the GPS terminal 100, and to monitor the battery level and various sensor information (e.g., temperature, humidity) of the GPS terminal 100. Furthermore, when an emergency call is issued from the GPS terminal 100, a push notification is sent to the monitoring terminal 300 to immediately inform the guardian of the emergency. It also functions as an external configuration terminal to remotely change various settings of the GPS terminal 100. The server 400 receives location and status information transmitted from the GPS terminal 100 and provides it to the monitoring terminal 300. It also plays a role in relaying messages and configuration information from the monitoring terminal 300 to the GPS terminal 100. This entire system allows guardians to check on their child's safety in real time and communicate quickly when necessary.

[0012] As shown in Figure 2, the GPS terminal 100 according to this embodiment is configured as a portable monitoring device housed in a compact casing, for example, approximately 5 cm in height, 5 cm in width, and 2 cm in thickness. This GPS terminal 100 is intended to be used by children attached to their school bags, backpacks, clothing, etc., and its small size and light weight are important features.

[0013] The GPS terminal 100 according to this embodiment is housed in an extremely compact casing with a length of about 5 cm, a width of about 5 cm, and a thickness of about 2 cm in order to enhance portability. In such a small display, when a user physically presses the display for operation, there may be a specific fundamental problem that the display surface, particularly the central part, is widely covered by the finger or the palm used for operation. Although there are conventional display switching technologies corresponding to touch operations, there has been no sufficient solution to the problem specific to small displays that "the display is hidden by the finger during physical pressing operations", particularly the problem that the necessary information becomes invisible at that time.

[0014] The reason why the technology according to the present disclosure is applied to the GPS terminal is that in this terminal used by children, the fact that important information such as battery remaining amount, callable time, and emergency messages becomes invisible by operation during an emergency is a serious problem directly related to the safety of children. Compared with general smartphones and tablet terminals used by adults, children are more likely to cover the entire small display even with small fingers, and are also likely to panic during an emergency. Therefore, the necessity of being able to surely visually recognize important information even during operation is extremely high. The technology according to the present disclosure effectively solves the problem of reduced information visibility during physical pressing in such an extremely small device, and has a remarkable effect that could not be predicted by the conventional technology in that it greatly contributes to ensuring the safety of children and improving the sense of security of guardians.

[0015] As shown in FIG. 3, the GPS terminal 100 includes, as main functional blocks, a display unit ("small display") 110, a detection unit 120 that detects input to the small display 110, and a display control unit 130 that controls the display of the small display based on the detection result. These functional blocks are mounted on a control board 240 described later. The display control unit 130 receives various information such as position information acquired from the GPS module 200, messages and emergency signals transmitted and received via the communication module 210, and remaining battery information of the battery 220, and determines the display content. Further, the communication module 210 also plays a role of performing wireless communication with an external setting terminal 230 (for example, a smartphone or a tablet terminal) operated by the parent and receiving information such as display settings. Thereby, the parent can flexibly customize the display settings of the GPS terminal 100 remotely.

[0016] As a specific hardware configuration of the GPS terminal 100, as shown in FIG. 4, a small display 110 for displaying information is arranged inside a rugged terminal housing. A pressure sensor 121 for detecting physical pressure applied to the display is incorporated under or around the display surface of the small display 110. Further, a touch sensor 122 for detecting contact such as a finger is integrally arranged on the surface of the small display 110. Detection signals from these pressure sensor 121 and touch sensor 122 are input to a control board 240 that controls the main functions of the terminal. The control board 240 has a microprocessor (CPU), memory (RAM, ROM), various I / O interfaces, etc., and executes a program for realizing various functions including the display control unit 130.

[0017] Furthermore, the GPS terminal 100 includes a GPS module 200 for acquiring position information, a communication module 210 for communicating with an external parent's smartphone or the like, and a battery 220 for supplying power to the whole.

[0018] The control board 240 is electrically connected to the GPS module 200, communication module 210, and battery 220, and works in conjunction with them to perform accurate positioning, stable communication, and efficient power management for the entire GPS terminal.

[0019] Figure 2 is a perspective view showing the external appearance of the GPS terminal 100 according to this embodiment. A small display 110 for displaying information is located in the center of the front of the housing 101. A bezel is provided around the small display 110 for ease of operation, and the shape is easy for children to grip. Physical buttons such as a power button and an emergency call button (not shown) may be located on the side of the housing 101. A strap hole (not shown) may also be provided for easy carrying by children. It is desirable that the housing 101 of the GPS terminal 100 be made of a material that is shock-resistant and waterproof.

[0020] Figure 3 shows the functional block configuration of the GPS terminal 100. The miniature display 110 is an output unit that visually displays information from the GPS terminal 100 and includes a first area 111 and a second area 112. The detection unit 120 is an input unit that detects user input to the miniature display 110 and is implemented by hardware such as a pressure sensor 121 and a touch sensor 122, which will be described later. The display control unit 130 is a central control unit that determines and controls the display content of the miniature display 110 based on signals from the detection unit 120, and its function is realized by the CPU on the control board 240 executing a predetermined program.

[0021] Figure 4 shows the main hardware configuration of the GPS terminal 100. The miniature display 110 is an integrated display that detects physical presses and touches and displays information, and displays visual information based on video signals sent from the display control unit 130. The pressure sensor 121 is a pressure detection means that converts the physical pressure applied to the miniature display 110 into an electrical signal for detection, and constitutes part of the detection unit 120, is connected to the control board 240, and outputs an analog or digital signal according to the amount of pressure. The touch sensor 122 is a contact detection means that detects contact of a finger or the like on the surface of the miniature display 110, and constitutes part of the detection unit 120, is connected to the control board 240, and outputs contact position and gesture information. The GPS module 200 is a positioning unit that receives signals from satellites and acquires the current location information of the GPS terminal 100, and the positioning results are sent to the display control unit 130 and used for map display and location information transmission. The communication module 210 is a communication unit that wirelessly communicates with an external network (mobile communication network, Wi-Fi, Bluetooth, etc.) and sends and receives data and messages with the parent external setting terminal 230. It is used for sending and receiving messages, receiving setting information, and transmitting emergency signals. The battery 220 is a power supply unit that supplies power to the entire GPS terminal 100. The remaining charge information is sent to the display control unit 130 and used for display and LED indicators. The control board 240 is a board that controls the entire GPS terminal 100 and consists of a microprocessor (CPU), ROM (read-only memory), RAM (random access memory), various I / O interfaces, timers, clock circuits, etc. The CPU executes programs stored in ROM to comprehensively control the operation of each functional block, such as the display control unit 130, GPS module 200, communication module 210, and battery 220. RAM is used as a working area when programs are executed and stores user settings and temporary data. The function of the display control unit 130 is implemented as a software module in which the CPU on the control board 240 processes signals from the detection unit 120 and controls the display of each area of ​​the miniature display 110 via a display driver.The control board 240 monitors input signals from the pressure sensor 121 and touch sensor 122 and incorporates logic to determine physical press based on a predetermined pressure threshold and duration. It also stores the types of information to be displayed (battery level, talk time, emergency messages, etc.) and their display rules (color, flashing pattern, priority) in memory and refers to them as needed. It receives signals from the detection unit 120 (pressure sensor 121, touch sensor 122) and outputs a display signal to the miniature display 110. It receives information from the GPS module 200, communication module 210, and battery 220, and determines the display content based on that information.

[0022] 2. Configuration and area of ​​small displays The small display 110 is a display device that forms the core of the user interface of the GPS terminal 100. Its display surface is logically and functionally divided into a first area 111 and a second area 112.

[0023] The first region 111 is defined as the region including the periphery of the small display 110. This region corresponds to the relatively outer part of the display that is not usually covered by the user's fingers or palm when the user physically presses the display to operate it. Specifically, the first region 111 may be set to an area less than 1 cm from the outer edge of the display. This definition clarifies the "peripheral region" in which visibility is easily ensured even during operation. The first region 111 means the part of the display relatively close to the edge that is not easily covered by the user's fingers or palm when a physical press operation is performed. Its range can be optimally set according to the size and shape of the display. In this specification, the "first region" is a concept that encompasses any displayable area that is not easily obscured by the user's fingers or palm when the display surface is physically pressed, and is not limited to a specific fixed region provided on the periphery of the display. For example, even if the entire display functions as a single display area, if the information displayed when a physical press is made is moved or reduced in size to the edges, corners, or designated non-obscured areas of the display that are less likely to be covered by the finger, that effective display area is interpreted as functioning as the "first area."

[0024] On the other hand, the second region 112 is an area that is at least partially enclosed by the first region 111 and corresponds to the central part of the display. This region is the part that the user's fingers directly touch during a physical press operation and is consequently easily covered over a wide area. The second region 112 means the central part that is enclosed by the first region and is easily hidden by the fingers during operation. In this specification, "second region" is a concept that encompasses any displayable area that is relatively easily concealed by the user's fingers or palm during a physical press operation, and refers to the actual area where information is hidden or moved to another area when a physical press is performed. Note that "the second region 112 is enclosed by the first region" does not mean that the second region 112 is not required to be completely (100%) enclosed by the first region. For example, it is a concept that can be included if 30% or more of the entire circumference of the first region is enclosed by the second region.

[0025] In this embodiment, the term "small display" is not limited to the size of a display mounted on a GPS terminal 100. For example, a compact housing approximately 5 cm in height, 5 cm in width, and 2 cm in thickness could include a display with a display area of ​​2 cm² to 15 cm². For example, a display of 100 cm² or less could qualify as a small display. The size range in this embodiment is significantly smaller than that of typical smartphone or tablet displays, and therefore the problem of the display surface being obscured by fingers during physical touch operations is particularly pronounced in this region. Various known technologies capable of displaying information can be used for the display method, such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).

[0026] 3. Configuration and operation of the detection unit The detection unit 120 is responsible for accurately detecting operations performed by the user on the small display 110. The main targets for detection are intentional user operations on the display. These intentional operations include physical presses, specific gestures, or combinations thereof.

[0027] It is more preferable to apply a pressure-sensitive sensor 121 as a specific configuration for the detection unit 120. The pressure-sensitive sensor 121 is placed directly below the display panel or in the surrounding frame area and detects changes in pressure (force) applied by the user to the display as an electrical signal. This physical press detection is distinct from simple surface contact (touch). The detection unit 120 may also further include a touch sensor 122 that detects contact with the display surface, such as a finger. The touch sensor 122 can use widely available and known touch detection technologies, such as capacitive or resistive touch sensors.

[0028] The detection unit 120 can strictly set detection conditions to prevent malfunctions caused by accidental contact or light pressure, and to detect only operations accompanied by the user's clear intention. Specifically, it may be configured to detect a physical press by detecting a press above a predetermined pressure threshold for a predetermined period of time or longer. For example, a "physical press" may be determined only when the pressure detected by the sensor exceeds a specific threshold (e.g., 0.5N) and that pressure continues for 0.5 seconds or longer. The specific determination conditions for "physical press detection" are not limited to the predetermined pressure threshold and continuous detection for a predetermined period of time or longer; furthermore, configurations that combine a specific number of consecutive physical presses (e.g., three or more) are also included in the scope of the technology of this disclosure. This dual detection condition clearly distinguishes between a simple light touch, accidental pressure in a pocket, or accidental contact by a child, and a user's intentional physical press, preventing transitions to unintended operating modes and dramatically improving the reliability of the operation.

[0029] Furthermore, if the GPS terminal 100 is equipped with both a pressure sensor 121 and a touch sensor 122, and both sensors react simultaneously, the display control unit 130 is controlled to prioritize the detection of a physical press by the pressure sensor 121. This ensures that important functions activated by a strong press by the user (e.g., emergency calls, sending voice messages to parents) are reliably executed without being confused with normal touch operations.

[0030] 4. Configuration and Operation of the Display Control Unit The display control unit 130 dynamically controls the display of information on the miniature display 110 based on the detection results from the detection unit 120. This control is a core function of the GPS terminal 100.

[0031] As shown in Figure 5, under normal circumstances, i.e., when the detection unit 120 does not detect a physical press, the display control unit 130 displays key information in the second area 112 (central area). This information includes the current time, date, or the face icon and name of the sender of the latest message from the parent. This information is placed in the central position that is most easily visible to the child when they look at the GPS terminal on a daily basis, and is designed to maximize visibility. In this case, the first area 111 (peripheral area) usually displays no information, or only very limited information (e.g., design elements).

[0032] However, when the detection unit 120 detects a physical press, the display control unit 130 switches the display mode. In this case, as shown in Figure 6, the second area 112 (central area), which is easily covered by the finger during a physical press operation, is left empty without displaying any information. Instead, important information related to the operation is displayed in the first area 111 (peripheral area), which is less likely to be covered by the finger. This makes it possible for the user to reliably see the necessary information without it being obscured by their finger, even while they are pressing the display firmly. This display switching is not limited to the form of "moving" information from the second area to the first area, but also includes, for example, in a configuration where the entire display functions as a single display area, the form of "adjusting the placement" of all the information displayed when a physical press occurs to the edge of the display that is less likely to be covered by the finger, or the form of "concentrating" the information at the edge. These forms also realize the technical idea of ​​the technology disclosed in this invention, which is to substantially avoid information obscuration by the user's finger and ensure information visibility.

[0033] The information displayed in the first area 111 is presented using one or more non-letter symbols, signs, or bars, so that even children can instantly understand it within the limited display space of a small display. This makes it possible to grasp information instantly and intuitively even in a small display area. In particular, since children may take time to recognize letters, these visually appealing representations greatly increase the reliability of information transmission in emergencies. For example, the remaining time available during a voice call with a parent is represented by a countdown bar. In addition, when the battery level is low, visual representations that intuitively convey the level of danger are used, such as lighting up the entire first area 111 in red, making the battery icon flash red, or changing the color of the battery level bar from green to yellow to red. Specifically, as shown in Figure 7, when the battery level is low, a red warning bar is displayed in the first area 111, and the battery icon flashes at the same time to emphasize the urgency. Furthermore, as the remaining talk time decreases, the countdown bar displayed in the first area 111 changes to red or flashes rapidly, visually conveying the urgency of "not much time left."

[0034] Information displayed in the first area 111 includes, in particular, the battery level (which is crucial for a GPS device), the remaining talk time for voice calls with parents, and information regarding the reception of emergency messages from parents. Because this information is directly related to ensuring the safety of children, it is prioritized and displayed in the first area 111 so that it can be reliably seen even when physically pressed. Specifically, a bar indicating the battery level decreases in stages, and when the remaining level is low, it changes to red and flashes to provide a visual warning. This allows children to intuitively understand the need to charge. The remaining time during a call is displayed as a countdown bar or number, and as the remaining time decreases, the color and flashing pattern change to help children decide whether to continue the call. When an emergency message arrives, a specific symbol (e.g., a bell mark) or icon is displayed in the first area 111 and highlighted with flashing or special colors (e.g., alternating red and white flashing) so that children can immediately notice the message and be prompted to check it.

[0035] The display control unit 130 may further control one or more of the types of information, priority, display threshold, display color, or flashing pattern displayed in the first area 111, so as to be changeable based on external setting input. For example, as shown in Figure 8, parents can flexibly customize the types of information they want to display on the GPS terminal 100 (e.g., battery level, talk time, emergency message reception, etc.) and how they are displayed (e.g., flash red when the battery level falls below 20%, flash yellow and red when an emergency message is received, etc.) through a dedicated app installed on their external setting terminal 230 (e.g., a smartphone). This external setting input is performed wirelessly (Bluetooth Low Energy (BLE) or Wi-Fi, etc.) via the communication module 210 of the GPS terminal 100, and the setting information is stored in the memory (not shown) of the GPS terminal 100. This makes it possible to provide optimal information tailored to the specific monitoring needs of each household and the characteristics of the child (e.g., visual cognitive ability), greatly improving practicality and convenience.

[0036] In this embodiment, the display control unit 130 is shown as controlling to directly display information in the first area 111 based on physical press detection by the detection unit 120, but the technology of this disclosure is not limited thereto. The display control unit 130 may further include a notification generation function that, when physical press detection occurs, notifies the user of some kind (e.g., sound, vibration, or illumination of an LED outside the first area) before displaying information in the first area 111. The display control unit 130 may then control to display information in the first area 111 only when the user makes a specific response to the notification (e.g., physically press again, give an affirmative response with sound, or press a specific physical button). In this case, the area where the information is displayed is either the same as the first area 111, or a separate display area dedicated to notification responses that has the functionality of the first area 111, and both are included within the scope of the technology of this disclosure. Such a configuration is interpreted as a sophisticated form of the display control process to make it more certain that physical press detection is not merely an error, and further improves user convenience and operational reliability.

[0037] 5. Display control processing flow The main display control processes performed by the display control unit 130 are carried out according to the flowchart shown in Figure 9. This flowchart details the logic for switching displays in response to physical button presses.

[0038] First, in step S101, it is determined whether or not any input (physical press or touch) to the display has been detected by the detection unit 120. If no input is detected (step S101: NO), the process proceeds to step S102, and the display control unit 130 continues in normal display mode. In this normal display mode, the state in which information such as the time and messages are displayed in the second area 112 (central area) is maintained.

[0039] If input is detected in step S101 (step S101: YES), the process proceeds to step S103 to determine whether the input is a physical press or not. This determination is made based on the signal from the pressure sensor 121. If it is determined in step S103 that it is not a physical press (step S103: NO, for example, a light touch operation in which only the touch sensor 122 reacts), the process proceeds to step S104, and the display control unit 130 performs display control according to the normal touch operation. In this case, the display in the second area 112 may continue, or a temporary UI element corresponding to the touch operation may be displayed.

[0040] If it is determined in step S103 that a physical press has occurred (step S103: YES), the process proceeds to step S105, where it is determined whether the detected physical press is above a predetermined pressure threshold and continues for a predetermined time or longer. This step functions as an important filter to prevent malfunctions due to accidental contact, etc., and to accurately detect only intentional physical presses by the user. For example, this threshold determination is achieved by continuously monitoring the signal value from the pressure sensor 121.

[0041] If it is determined in step S105 that the conditions are not met (step S105: NO, for example, a light press or a momentary press), the process returns to step S102, and the display control unit 130 continues the normal display.

[0042] On the other hand, if it is determined that the condition is met in step S105 (step S105: YES, determined to be an intentional physical press), the process proceeds to step S106. The display control unit 130 turns off the display of the second area 112 (central area). This intentionally hides the information in the central area that may be hidden by the finger during a physical press operation.

[0043] Next, in step S107, the display control unit 130 displays important information related to the operation (for example, a countdown bar showing the remaining talk time, a warning display showing the battery level, etc.) in the first area 111 (peripheral area). This display is in an intuitive format that is not based on text.

[0044] In step S108, it is determined whether the physical press is continuing. If the press is continuing (step S108: YES), the process returns to step S107 and continues displaying in the first area 111.

[0045] If it is determined in step S108 that the button has been released (step S108: NO), the process proceeds to step S109, and the display control unit 130 returns the display to the normal display (step S102) after a predetermined time has elapsed, for example, a few seconds after the end of a call. This automatically returns to the normal information confirmation mode after the operation is completed, without impairing user convenience.

[0046] 6. Other Embodiments In the above embodiment, the information display in the first region 111 was described as being performed on the display surface of the miniature display 110, but the technology of this disclosure is not limited thereto. As shown in Figure 10, the first region 111 may be composed of a plurality of light-emitting diodes (LEDs) provided on the outer edge of the housing of the GPS terminal 100, separately from the display surface of the miniature display 110.

[0047] In this embodiment, the display control unit 130 displays information by controlling one or more of the following: lighting, flashing, or changing the color of the multiple light-emitting diodes (LEDs) when a physical press is detected. For example, if the battery level is low, the LEDs flash red to emphasize the urgency, and if the communication status is good, they light up green to provide a sense of security. Alternatively, when an emergency message is received from a parent, an LED of a specific color flashes rapidly, enabling intuitive information provision by externally provided LEDs even when the display is covered by a finger.

[0048] This LED display offers a significant advantage in ensuring reliable information transmission, as it maintains high visibility even when the display is completely covered by physical pressure. Furthermore, it consumes less power than a traditional display, contributing to continuous information delivery, such as extended information display and low battery warnings, in small devices with limited battery life. It also boasts high durability against physical impact, allowing for greater design versatility.

[0049] Figure 10 shows another embodiment of the LED light display. The housing 101 (outer edge) is the physical outer frame of the GPS terminal 100, and multiple LEDs 105 are embedded therein. The LEDs 105 are light-emitting diodes arranged independently of the small display 110, and can be single-color LEDs or multi-color LEDs such as RGB LEDs. They light up, blink, or change color based on control signals from the display control unit 130. Functionally, they visually convey information even when the display is hidden, such as when a physical press is detected or when a specific notification occurs. For example, they can blink rapidly in red during an emergency call and blink slowly in blue when a message is received.

[0050] 7. Additional screen examples and operation explanations In addition to the above, the display control function of this embodiment can have various display variations to suit different situations.

[0051] Figure 11 shows an example of the display in the first area of ​​the call screen. When a user physically presses the display while the GPS terminal 100 is making a voice call, the display control unit 130 hides the caller information and other information displayed in the second area and displays information about the current call status in the first area. Specifically, a bar 1001 showing the call duration, a numerical value 1002 showing the remaining call time (e.g., 2 minutes 30 seconds remaining), or a countdown icon 1003 until the end of the call is displayed. This allows the user to reliably understand the call status even while on a call, without their finger obscuring it. This is particularly effective in preventing children from accidentally running out of call time.

[0052] Figure 12 shows an example of the screen and LED linked display when an emergency call is activated. When the emergency button (not shown) of the GPS terminal 100 is physically pressed, or when the detection unit 120 detects a specific physical press pattern (e.g., pressing and holding the center of the display for 5 seconds or more), the GPS terminal 100 switches to emergency call mode. At this time, as shown in Figure 12, the display control unit 130 displays an icon 1101 indicating "Emergency Call in Progress" and a message 1102 indicating the status of location information transmission (e.g., "Transmitting Location Information") in the first area 111. Simultaneously, the display control unit 130 controls the LED 105 provided on the outer edge of the housing 101 to flash rapidly in high-brightness red. This visually notifies not only the user but also those around them that an emergency has occurred, leading to early detection and assistance. Furthermore, even if the display is completely hidden, the status can be understood from the flashing LED, significantly improving the reliability of information transmission in emergencies.

[0053] Figure 13 shows an example of the display in the first area when the battery is low (gradual change). When the remaining battery level of the GPS terminal 100's battery 220 falls below a predetermined threshold, the display control unit 130 displays information about the battery level in the first area 111 when the user physically presses the display. This display can be changed in stages according to the degree of battery level depletion. For example, when the battery level falls below 50%, a green battery level bar 1201 is displayed in the first area 111, and when it falls below 20%, it changes to a yellow bar 1202 and a warning icon 1203 (e.g., a battery mark) flashes. Furthermore, when the remaining level becomes very low, such as below 5%, it changes to a red bar 1204 and the warning icon 1203 flashes rapidly to prompt immediate charging. Through such gradual visual changes, the user can intuitively and accurately grasp the battery level and take appropriate action.

[0054] 8. Additional flowcharts and operation instructions The detection and control processes in this embodiment can be represented by a more detailed flowchart.

[0055] Figure 14 is a flowchart for changing display settings using an external configuration terminal. This flowchart shows the process by which a parent can remotely customize the display settings of the GPS terminal 100.

[0056] First, in step S201, the parent launches the dedicated setting application for the GPS terminal 100 on the external setting terminal 230. Next, in step S202, the parent selects display setting items within the application (e.g., battery warning display threshold, emergency message display priority, LED flashing pattern, etc.). In step S203, the parent enters new setting values ​​for the selected setting items (e.g., red flashing at 20% battery, voice notification also used when an emergency message is received, etc.). Once the input is complete, in step S204, the setting information is transmitted wirelessly to the GPS terminal 100 via the communication module 210. On the GPS terminal 100 side, in step S205, the communication module 210 receives the setting information, and in step S206, the display control unit 130 analyzes the received setting information and updates the display settings stored in the memory of the GPS terminal 100. As a result, the new display settings are immediately reflected in the GPS terminal 100, realizing a monitoring function that aligns with the parent's intentions.

[0057] Figure 15 is a detailed judgment flowchart of the detection unit. This flowchart shows how the detection unit 120 precisely determines the "physical press detection" that triggers the display switching.

[0058] First, in step S301, the pressure value from the pressure sensor 121 to the display is continuously acquired. Next, in step S302, it is determined whether the acquired pressure value exceeds a predetermined pressure threshold (e.g., 0.5N). If the threshold is not exceeded (step S302: NO), the process returns to step S301 and continues monitoring the pressure. If the threshold is exceeded (step S302: YES), the process proceeds to step S303.

[0059] In step S303, it is determined whether the condition of being above this pressure threshold has continued for a predetermined time (e.g., 0.5 seconds) or longer. This determination of the duration is performed using a timer function or the like. If it has not continued (step S303: NO), the process returns to step S301. This is to eliminate momentary contact or accidental pressure fluctuations.

[0060] If it is determined in step S303 that the process is continuing (step S303: YES), the process proceeds to step S304. In step S304, it is determined whether this physical press has been detected continuously for a predetermined number of times (e.g., 3 times) or more. This count determination is performed using a counter function or the like. If the number is less than the predetermined number (step S304: NO), the process returns to step S301 and pressure monitoring continues.

[0061] If it is determined in step S304 that the number of presses has exceeded a predetermined number (step S304: YES), a "physical press detection confirmation signal" is sent to the display control unit 130, and the display mode switching process (from step S106 onwards in Figure 9) is initiated. This multi-stage determination process recognizes only the user's intentional operations with extremely high accuracy, preventing unnecessary display switching and function activation, thereby dramatically improving the reliability and usability of the GPS terminal.

[0062] The components in each of the embodiments described above (e.g., combination of pressure sensor and touch sensor, use of LED light, specific examples of display content, customization function, etc.) can be combined as appropriate depending on the purpose and effect. This enables diverse uses of the technology in this disclosure and flexible protection of rights in response to future technological developments.

[0063] This application includes the following issues and their solutions.

[0064] (General tasks) In devices with small displays, users may not be able to easily grasp the information they need when operating the display.

[0065] (Note 1) Issues corresponding to (Appendix 1) Information may be missed during physical button presses on GPS terminals equipped with small displays.

[0066] (Note 1) A GPS terminal equipped with a small display, wherein the small display comprises a first region including the periphery of the small display and a second region at least partially surrounded by the first region, a detection unit for detecting physical pressing of the small display, and a display control unit for controlling the display of the small display based on the physical pressing detection by the detection unit, wherein the display control unit displays information in the second region when there is no physical pressing detection, and displays information in the first region when a physical pressing is detected.

[0067] (Effects of Appendix 1) By displaying information in the peripheral area (first area) that is less likely to be covered by a finger during physical operation, rather than in the central area (second area) that may be obscured by a finger, important information can be easily grasped even during operation. This prevents information from being missed during operation and enables reliable information transmission.

[0068] More specifically, according to the technology disclosed herein, in a terminal equipped with a small display, when the display is physically pressed, information is not displayed in the central area (second area) that is easily obscured by the operating finger, but is displayed in the peripheral area (first area) that is less likely to be covered by the finger. This allows users to smoothly and reliably grasp information without missing important information even while operating the terminal. This technological effect solves the fundamental problem of reduced information visibility during operation that conventional small display terminals have suffered from. In particular, the technology disclosed herein has a remarkable effect that could not be predicted with conventional technology, as it ensures the reliable visibility of important information such as battery level and emergency messages in emergency situations in GPS terminals used by children, greatly contributing to ensuring the safety of children and improving the peace of mind of parents.

[0069] To explain in more detail, the technology disclosed herein offers the following advantages. First, it significantly improves usability. Even during physical button presses, the information the user needs remains visible at all times, allowing for continued operation without hesitation and enabling quick action, especially in emergencies. This prevents users from missing information directly related to their safety, such as low battery levels or emergency messages, and provides added value unique to GPS terminals.

[0070] (Note 2) Issues corresponding to (Appendix 2) Intuitive information transmission in small peripheral areas where text display is difficult.

[0071] (Note 2) A GPS terminal as described in the above appendix, wherein the display control unit displays information in the first area using one or more non-character codes, symbols, or bars. (Effects due to Appendix 2) Within the limited display space of a small screen, visual representations that do not rely on text allow children in particular to intuitively understand information and grasp the situation instantly. This aligns with the characteristics of visual perception and reduces misinterpretation.

(Effects of Appendix 3) By using both pressure-sensitive and touch sensors, intentional physical presses are prioritized for detection, preventing malfunctions caused by accidental touches and ensuring reliable activation of critical functions, especially in emergencies.

[0074] (Note 4) Issues corresponding to (Appendix 4) Flexibility in displaying information to meet user needs.

[0075] (Note 4) A GPS terminal as described in the above appendix, characterized in that the display control unit controls one or more of the types, priority, display thresholds, display colors, or flashing patterns of information displayed in the first area, based on external setting input.

[0081] (Note 7) A GPS terminal as described in the above appendix, wherein the display control unit displays information relating to one or more of the following in the first area: battery level, talk time, or emergency message reception. (Effects of Appendix 7) As a GPS monitoring device, it reliably provides children with particularly important and urgent information (such as low battery level, dropped calls, and emergency contacts) even while they are being operated, thereby ensuring their safety and increasing peace of mind for parents.

[0082] (Note 8) Issues corresponding to (Appendix 8) The accuracy and reliability of detecting intentional user actions.

[0083] (Note 8) A GPS terminal as described in the above appendix, wherein the detection unit detects a physical press by detecting a press of the small display at a predetermined pressure threshold or higher for a predetermined period of time or longer. The term "intentional operation by the user" as used herein includes detecting a press of the small display at a predetermined pressure threshold or higher for a predetermined period of time or longer, or a specific gesture detected by the terminal's accelerometer or gyroscope, or a specific operation pattern detected by a combination of multiple touch sensors. (Effects of Appendix 8) By eliminating mere contact or accidental pressure and accurately detecting only operations accompanied by a clear user intent, system malfunctions are prevented, dramatically improving operational reliability and safety.

[0085] (Note 9) A GPS terminal as described in the above appendix, further comprising an ambient light sensor for detecting ambient light, wherein the display control unit adjusts the brightness of the information displayed in the first and / or second regions based on the detection result of the ambient light sensor. (Effects of Appendix 9) By automatically adjusting the display brightness according to ambient light, visibility is always optimized while reducing battery consumption caused by unnecessary brightness.

[0086] (Note 10) Issues corresponding to (Appendix 10) Integration of voice notifications and visual displays.

[0087] (Note 10) A GPS terminal as described in the above appendix, further comprising a speaker for outputting sound, wherein the display control unit, upon detection of the physical press, simultaneously displays information in the first area and outputs an audio notification corresponding to the information from the speaker.
