It is shown that As the range data, in addition to the range surrounded by the position coordinates, for example, the range corresponding to the icon ID "002" is surrounded by a circle with a radius R1 centered on the position coordinates P5 as the reference of the range. It can also be defined as Further, like the icon ID “003”, a range surrounded by a circle with a radius R2 centered on the position coordinates P6 and a range surrounded by a circle centered on the position coordinates P7 with a radius R3 are set to a school (not attending school) range. ) can also be in the range. ID "004" is based on the same idea. That is, what is enclosed in parentheses (for example, (P5, R1)) indicates one range defined by the position information and radius information in the parentheses. As described above, when there are multiple items enclosed in parentheses, the combined range of the respective ranges becomes the range information. The data format for the range information of the target icon ID table 1 is automatically generated by the icon display setting unit 217 . In addition, the recorded range information can be stored in a data format (surrounded by three or more position coordinates) by tapping the target range information 92 displayed as having been set on the screen shown in FIG. , a circle defined by one positional coordinate and one radius information, etc.) and the positional coordinates can be manually modified by the user. Further, the mobile terminal 20 may store the information of the icon data table 3, which will be described later, in the auxiliary storage unit 23 when the application program (app) is installed.

In this embodiment, the schedules registered for each of the children A and B are stored in the auxiliary storage unit 23 as the schedule table 2 . The schedule registration in the schedule table 2 can be easily executed by linking with, for example, a calendar function or a schedule book function installed in the mobile terminal 20 . FIG. 7 shows a configuration example of the schedule table 2. As shown in FIG. In the schedule table 2, for example, items such as date, day of the week, time zone, schedule (location), and remarks (name of each schedule, such as “cram school” and “club activity”) are provided for each terminal ID to be monitored. is provided. FIG. 7 is an example of a child A to whom a terminal ID “A” is assigned. It is indicated that child A is scheduled to stay at Y elementary school, which is not the school that child A attends, until 18:30 due to extracurricular activities. As will be described later, in the case where there is a school that the child A attends and a school that the child A does not attend, the configuration is such that different icons can be assigned to the X elementary school and the Y elementary school. .

<Display terminal>
Next, the configuration of the display terminal 30 will be described. As described above, the hardware configuration of the display terminal 30 in the present embodiment is substantially the same as the configuration of the positioning terminal 10 illustrated in FIG. 2, so description thereof will be omitted.

Each icon has a positioning terminal 10 such as facilities (features) such as "home", "school", and "park", "commuting to and from school", and "moving to the place of learning" (behavior). It is possible to intuitively grasp the current position and behavior of the child being watched over at a glance without using map information (features such as facilities, roads, etc.) around the current position according to the current position and activity type of the child being watched over. It is an image designed to "Cram School", "Music Class", "Swimming", "Abacus Class", "Calligraphy", "English/English Conversation", "PC/Programming", "Martial Arts Class", "Ballet Class" in icon data table 3 , ``baseball club'', and ``soccer club'' represent facilities (features) such as facilities for club activities such as lessons and sports, classrooms, plazas, and ball game fields. It should be noted that whether or not the target is performing an action is determined by whether the time-series data of the location information transmitted from the positioning terminal 10 is within the range set as "commuting to and from school" or "moving to the place of learning". Judge by what. As will be described later, each icon display data is created in advance according to the display area and resolution of the display device provided in the display terminal 30 such as a smartwatch.

<Icon Display Processing in Display Terminal 30>
The icon display on the display terminal 30 of this embodiment is
(1) Calculation of location information based on positioning satellite signals in the positioning terminal 10 and transmission of the location information to the mobile terminal 20 (2) Based on the location information received from the positioning terminal 10 and the set range information Determining the current position of the target, determining whether it is within any range, determining whether it is taking a specific action, extracting the icon ID based on the determination result, and transmitting it to the display terminal 30 (3) From the mobile terminal 20 The positioning terminal 10, the mobile terminal 20, and the display of reading the corresponding icon display data based on the received icon ID and displaying the icon display data in a display form determined based on the reception timing, the attitude and movement of the display terminal 30 It is realized through cooperation of the terminals 30 and data processing by each terminal device. The icon display processing will be described below with reference to a data processing flow example in this embodiment.

FIG. 10 is a flowchart showing an example of icon display processing on the display terminal 30 in this embodiment. The processing flow of FIG. 10 starts with reception of positioning satellite signals by the positioning terminal 10 on the left side of the page. It is assumed that the positioning terminal 10, mobile terminal 20, and display terminal 30 are powered on and in operation.

In step S<b>1001 , the location information acquisition unit 114 of the positioning terminal 10 performs positioning processing based on the positioning satellite signals from the positioning satellites GS received by the GNSS unit 16 . In step S<b>1002 , the location information acquisition unit 114 uses the positioning result in step S<b>1001 to calculate location information consisting of latitude and longitude indicating the current location of the positioning terminal 10 . In step S<b>1003 , the location information acquisition unit 114 transmits the calculated location information to the mobile terminal 20 .

Although not shown in FIG. 10, the positioning terminal 10 may upload the location information to a server located on the network N once. In this case, the mobile terminal 20 accesses the server at appropriate timing and downloads and acquires the location information uploaded by the positioning terminal 10 .

In step S1004, the current location information receiving unit 215 of the mobile terminal 20 waits to receive location information from the positioning terminal 10 (No in step S1004). If it is determined that position information has been received (Yes in step S1004), the current position information receiving unit 215 executes reception processing in step S1005. In step S<b>1006 , the current position determination unit 216 of the mobile terminal 20 compares and determines whether the received position information is included in any range stored in the target icon ID table 1 . If it is determined that the received position information is included in any range (Yes in step S1006), in step S1007, the current position determination unit 216 selects the icon ID associated with the range as the target icon. It reads out from the ID table 1 and transmits it to the display terminal 30 . If it is determined that the received position information is not included in any range (No in step S1006), the current position determination unit 216 determines that the target name information is associated with "not applicable" in step S1008. The icon ID “000” is read from the target icon ID table 1 and transmitted to the display terminal 30 .

In step S1009, which is before the icon ID information is received from the mobile terminal 20, the display terminal 30 configured as a smart watch displays the time display screen of the digital clock, which is the normal display. An example of the time display screen is shown in FIG. 11A.

In step S1010, the icon display control unit 316 of the display terminal 30 waits until the icon ID is received from the mobile terminal 20 (No in step S1010). If it is determined that the icon ID has been received (Yes in step S1010), the icon display control unit 316 executes icon ID reception processing in step S1011. In step S1012, the icon display control unit 316 of the display terminal 30 determines whether or not a predetermined time has passed since the previous reception of the icon ID. If it is determined that the predetermined time has not elapsed (No in step S1012), the icon display control unit 316 waits until reception of the next icon ID. This process reduces or eliminates the annoying feeling that may be given to the user due to frequent switching of the screen display on the display terminal 30 to the icon main display described later in response to reception of the icon ID from the mobile terminal 20. This secures the time for restricting display switching.

In step S1012, when the icon display control unit 316 determines that the predetermined time has passed since the previous reception of the icon ID (Yes in step S1012), in step S1013, the icon display control unit 316 changes the icon data The icon display data corresponding to the icon ID is read out from the table 3, and processing for displaying only the corresponding icon on the display screen of the display terminal 30 is performed. FIG. 11B shows an example of a display screen displaying only the corresponding icon. In the example of FIG. 11B , the entire display screen of the smart watch, which is the display terminal 30, is used to display the icon image indicated by the icon display data “commuting to and from school (moving on school route)” (icon ID=004). there is In the present application, such a display mode in which icons are displayed using the entire display screen of the display terminal 30 is referred to as "icon main display". As shown in FIG. 11B, icons are displayed using the entire display screen of the display terminal 30 such as a smart watch that the parent wears. Even if P cannot operate the mobile terminal 20 immediately, the map information (buildings, roads, etc.) surrounding the target (buildings, roads, etc.) indicates where the child C who is the target (watching target) is, or what actions are being taken. It is possible to intuitively understand and comprehend without displaying attributes (including character information representing building names, road names, etc.). In other words, the icon image displayed on the output unit 35 of the display terminal 30 can easily inform the guardian P of where the child C is or what action the child C is taking.

Returning to the description of FIG. 10, in step S1014, the icon display control unit 316 continues the icon main display for a predetermined time (for example, 10 seconds) set by the timer. After the predetermined period of time has elapsed, in step S1015, the icon display control unit 316 displays the icons displayed on the entire display screen of the display terminal 30 by the icon main display in a small size by moving them to one of the corners of the display screen. Switch to display mode. In the present application, such a display mode is referred to as "icon sub-display". FIG. 11C shows an icon sub-display example. In FIG. 11C, the display terminal 30 in the form of a smart watch displays a digital clock, which is an original function, and the icon indicating "commuting to and from school" in the upper right of the display screen is displayed smaller than the icon main display. there is According to this icon sub-display, it is possible to know the whereabouts and behavior of the target child C while using the original functions of the display terminal 30 .

<Other Display Modes of Display Terminal 30>
11D-11F show other display modes on the display terminal 30. FIG. FIG. 11D shows the icon "moving to lessons" (30C) in the icon data table 3 of FIG. 9 in the icon main display mode. is displayed. This indicates that the child C who has the positioning terminal 10 is moving to a lesson such as a music class, and that the lesson start time is 7 minutes and 54 seconds. Such a display can be achieved by, for example, pre-storing the child C's activity schedule in the schedule table 2 of the mobile terminal 20, and comparing the activity schedule with the time when the position information is received from the positioning terminal 10. Calculate the remaining time until the next appointment. Then, the mobile terminal 20 indicates the icon ID information (021) corresponding to "moving to the place of the lesson" and "07:54 until the start" from the time-series data of the location information and the action schedule from the positioning terminal 10. It can be realized by transmitting the information to the display terminal 30 .

FIG. 11E shows an example of graphically displaying the weather (30E) at the current location of the positioning terminal 10 on the display screen of the display terminal 30 in the icon main display mode. The weather at the current location of the positioning terminal 10 can be obtained by, for example, a method in which the mobile terminal 20 that has received the location information from the positioning terminal 10 acquires weather information from an external device via the Internet using the location information. can. According to this, the guardian P can know the weather of the place together with the location of the child C, so that it can be used for judgment such as whether it is necessary to bring an umbrella when picking up the child C.

FIG. 11F is an example of graphically additionally displaying the watching situation on the school route on the icon main display screen for the icon indicating "commuting to and from school". That is, in the example of FIG. 11F, an image of five small flags (30F) is displayed above the "to/from school" icon. In some cases, parents and volunteer staff keep watch over children at key points on school routes to ensure the safety of children on their way to and from school. A positioning terminal 10 such as a smart watch possessed by a child and a mobile terminal such as a smart phone possessed by a parent or volunteer staff are enabled to perform data communication by short-range wireless communication, and the positioning terminal of the child is provided. Each time positioning terminal 10 performs data communication with the mobile terminal of a guardian or volunteer staff, positioning terminal 10 transmits information indicating that data communication has been performed to mobile terminal 20 . Upon receiving the information, the mobile terminal 20 determines that the positioning terminal 10 on the way to and from school has passed a point where a parent or volunteer staff is present at a key point. image data of a flag indicating ) is transmitted to the display terminal 30 at any time. As a result, the display terminal 30 can indicate the progress of the child C on the school route used for commuting to and from school by the number of displayed flag images. Therefore, in the present application, for example, instead of a general display (a display with a large amount of information) in which the current position of the child C is superimposed on the map displayed on the output unit 35 of the display terminal 30, the watching target is shown in FIG. The current position of the child C can be grasped intuitively by a simple display of only the image indicating the location and the supplementary information (the number of flag images) regarding the location.

FIG. 12 is a flowchart showing another example of icon display processing on the display terminal 30 in this embodiment. The processing flow of FIG. 12 starts with reception of positioning satellite signals by the positioning terminal 10 on the left side of the page, as in FIG. It is assumed that the positioning terminal 10, mobile terminal 20, and display terminal 30 are powered on and in operation. FIG. 12 shows an example of display on the display terminal 30 when the positioning terminal 10 is once determined to be within a certain range in the process flow of FIG. 10 and then goes out of that range.

In step S1201, the location information acquisition unit 114 of the positioning terminal 10 transmits the location information calculated in steps S1001 and S1002 of FIG.

In step S1202, the current location information receiving unit 215 of the mobile terminal 20 waits to receive location information from the positioning terminal 10 (No in step S1202). If it is determined that position information has been received (Yes in step S1202), the current position information receiving unit 215 executes reception processing in step S1203. In step S<b>1203 , the current location information receiving unit 215 of the mobile terminal 20 performs a process of receiving location information from the positioning terminal 10 . In step S<b>1204 , the current position determination unit 216 of the mobile terminal 20 compares and determines whether the received position information is outside any range stored in the target icon ID table 1 . If it is determined that the received position information is still included in any range (No in step S1204), the current position determination unit 216 continues monitoring the position information. If it is determined that the received location information is not included in any range (Yes in step S1204), the current location determination unit 216 determines in step S1205 that the positioning terminal 10 is included immediately before. An icon ID corresponding to the range is read from the target icon ID table 1 and transmitted to the display terminal 30 .

In step S1206, the icon display control unit 316 of the display terminal 30 waits until the icon ID is received from the mobile terminal 20 (No in step S1206). If it is determined that the icon ID has been received (Yes in step S1207), the icon display control unit 316 executes icon ID reception processing in step S1207. At this point, the display terminal 30 configured as a smartwatch is performing icon main display or icon sub-display for the icon corresponding to the immediately preceding position range.

In step S1208, the icon display control unit 316 of the display terminal 30 "inverts black and white" for the icon main display for the icon corresponding to the immediately preceding range. This reverse display allows the parent P wearing the display terminal 30 to know that the child C has left the location.

In steps S1209 to S1211, icon display control unit 316 continues the inverted icon main display for the time set by the timer, and then returns to normal display in FIG. 11A in step S1212. That is, in step S1209, icon display control section 316 initializes and starts a timer. In step S1210, the icon display control unit 316 waits until a predetermined period of time has elapsed since the timer was started (No in step S1210). If it is determined that the predetermined time has elapsed (Yes in step S1210), the icon display control unit 316 stops the timer for initialization, and then proceeds to the process of step S1212.

FIG. 13 shows a flowchart of a modification of the icon display process on the display terminal 30 shown in FIG. The processing flow of FIG. 13 is almost the same as the processing flow of FIG. 10, but the processing of suppressing frequent icon display switching in S1009 is different from that of FIG. Here, for the sake of simplicity, this different processing part will be explained.

That is, in FIG. 13, if it is determined in step S1012 that the predetermined time has not passed since the icon ID was received last time (No in step S1012), the icon display control unit 316 further proceeds to step S1012A. Determine the importance of the icon ID. If it is determined that the importance of the received icon ID is not low (No in step S1012A), the icon display control unit 316 performs the icon main display in step S1013 even before the predetermined time has elapsed. If it is determined that the received icon ID is of low importance (Yes in step S1012A), the icon display control unit 316 executes icon sub-display in step S1015. It should be noted that the determination of whether or not the importance of the icon ID in step S1010A is low is made by comparison with a preset reference value (threshold value).

In this way, the degree of importance is set according to the icon ID, and for the icon ID with high degree of importance, the icon main display is performed on the display terminal regardless of the elapsed time since the icon main display was performed last time. Thus, the parent P wearing the display terminal 30 can know without delay when the child C enters a place of high importance regardless of the frequency of the icon main display. Here, the importance of the icon ID can be determined by the icon display control unit by providing items such as importance A (high), B, and C (low) corresponding to the icon ID in the target icon ID table 1. 316 can be used for determination processing. In this case, the degree of importance can be appropriately defined according to criteria such as, for example, public behavior (eg, going to school) is more important than private behavior (eg, visiting a friend's house, hairdressing). Regarding the setting of the degree of importance, when setting the target range information 92, the target icon information 93, the target name information 94, etc. using the screen of FIG. , etc., may be set together.

<Other display processing>
FIG. 14 shows another example of display processing on the display terminal 30 in this embodiment. In the example of FIG. 14, the icon display control unit 316 of the display terminal 30 is configured to display an image showing the passage of time in the case of the icon main display. That is, in FIG. 15, an icon (30C) representing a "park" is displayed in the icon main display mode, accompanied by an image (30G) representing the passage of time, in which a frog grows from an egg to a tadpole to adulthood. 14(A) to 14(E). When displaying the icon indicating the passage of time, the child C to be watched over enters a location not registered in the schedule table 2 of the mobile terminal 20, such as the "park" illustrated in FIG. The icon display control unit 316 can control to display the icon on the display terminal 30 when the icon is displayed.

Icons for indicating the passage of time can adopt an easy-to-understand appropriate motif, such as a frog growing from an egg or plants growing from a seed, as shown in FIG. 15, for example. In FIG. 15, for example, in the case of a frog, each stage of an egg, a tadpole, a tadpole with hind legs, a frog with a remaining tail, and an adult frog is set to represent 15 minutes. By displaying such an icon representing the passage of time together with an icon representing a place, for example, in the example of FIG. Parent P wearing 30 can take actions such as encouraging child C to go home early by phone or e-mail. Further, the above display processing is not limited to the fact that the child C enters a place not registered in the schedule table 2 of the mobile terminal 20 for the current day. The display process may be performed even when the child C enters the location registered in the schedule table 2 of the mobile terminal 20 .

Also, the exercise information acquisition unit 116 of the positioning terminal 10 acquires the movement (activity) status of the positioning terminal 10 (walking, running, moving by bicycle, etc.) based on each measurement value obtained from the sensors included in the sensor unit 17. may be detected and transmitted to the mobile terminal 20 via the communication unit 18 . Then, the portable terminal 20 may cause the output unit 35 of the display terminal 30 to display an image related to the activity based on the acquired movement (activity) situation and the icon data table 3 . In this case, the name of the activity (walking, running, biking, etc.) included in the detected movement state is compared with the information of the name, which is a constituent element of the icon data table 3, and the corresponding icon display data is generated. Extract (for example, "walking" means going to and from school, "biking" means traveling to a place of learning, etc.).

Further, although icon display data (still image) is registered as an icon in the icon data table 3 in this embodiment, the present invention is not limited to this. A moving image (which may include sound) may be registered as an icon.

The information about the object may be information about the current location of the object and information about the activity.

In this way, the display terminal 30 can grasp the current position and activity of the child C to be watched over.

The processing unit 31 of the display terminal 30 may prevent the output unit 35 from displaying other images showing features near the current position.

In this way, on the display terminal 30, it is possible to intuitively grasp only the current position and activities of the child C to be watched over.

The processing unit 31 causes the output unit 35 to display the icon associated with the acquired position information in the first size, and after a predetermined time has elapsed, displays the icon in the second size smaller than the first size. may be displayed on the output unit 35 by .

In this way, the limited display area of the output section 35 of the display terminal 30 can be effectively used.

The processing unit 31 may display the icon of the second size and other information on the output unit 35 so as not to overlap each other.

In this way, on the display terminal 30, the current position of the object such as the child C can be confirmed by the icon, and other information such as the clock displayed by the function of the display terminal 30 can also be visually recognized.

Based on position information indicating the current position of the child C and information on the object such as the child C held at the time of acquisition of the position information, the processing unit 31 displays the position information on the display terminal. The icon displayed on the output unit 35 of 30 may be changed and displayed on the output unit 35 .

In this way, the icon display on the output unit 35 of the display terminal 30 can indicate whether the facility is the same school as the target child C is attending or other schools. It can be identified at a glance, and the current position of the object can be known more specifically.

The processing unit 31 determines whether the position information indicating the current position of the target is within a preset range, and determines that the target has left the range based on the position information of the target. When it is determined, the display mode of the icon displayed on the output unit 35 may be changed and displayed.

In this way, it can be known that the target has moved out of a specific range and has moved on to the next action.

The processing unit 31 acquires weather information at a point where the target exists from an external device on the network N based on the position information indicating the current position of the target, and causes the output unit 35 to display the weather information. may

In this way, it is possible to take measures (such as picking up the child C) as necessary based on the weather information at the current position of the target.

Based on the position information indicating the current position of the target, the processing unit 31 displays an icon representing the elapsed time since entering the facility when the target is staying in the facility indicated by the icon. , may be displayed on the output unit 35 of the display terminal 30 .

In this way, the parent or the like of the child C, who is the subject, can call attention according to the time of staying in the range by means of telephone, e-mail, etc., or urge them to leave as soon as possible.

The processing unit 31 may cause the output unit 35 to display icons related to at least one of facilities and activities at the current position of the target.

In this way, the guardian or the like can intuitively grasp the situation of the child C to be watched over.

Further, the embodiment of the present invention includes: a positioning terminal 10 that transmits information about an object; It can be configured as a display control system that includes the processing unit 31 that causes the output unit 35 to display icons related to at least one of the activities.

In this case, the positioning terminal 10 is configured as a wireless terminal device driven by a battery, and at least one of information about the state of the battery and information indicating the state of wireless communication of the positioning terminal 10 is sent to the display terminal 30. You may make it

In this way, a parent or the like who owns the display terminal 30 can easily know the cause when it becomes difficult or impossible to receive the position information from the positioning terminal 10. .
