<< Operation of map information display system 100 >>
Various processes performed by the map information display system 100 configured as described above will be described below. The various processes described below in the present embodiment are based on the premise that the smartwatch 1 and the smartphone 2 are in a state of mutual data communication.

(Map information display switching process)
First, the map information display switching process performed by the map information display system 100 of the present embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart showing an example of the map information display switching process according to the present embodiment. FIG. 6 is a diagram showing an example of a screen displayed on the display unit 104 when the user browses the map information.

The map information display switching process is performed when a predetermined operation is performed by the operation input unit 102 of the smart watch 1 at an arbitrary timing when the user wants to view the map information.
Further, the display of the map information on the display unit 104 in the map information display switching process is not intended to guide the user to the destination set by the user, such as a navigation terminal, but the user. It is done for the purpose of providing the map information itself.

First, as shown in FIG. 5, the CPU 101 of the smart watch 1 requests the current position information from the smartphone 2 by the communication unit 106 (step S101).

Next, the CPU 201 of the smartphone 2 acquires the current position information indicating the user's current position by the satellite radio wave receiving module 208, and transmits the current position information to the smart watch 1 by the communication unit 206 (step S102).

Next, the CPU 101 of the smart watch 1 acquires the current position information by the communication unit 106 (step S103).

Next, the CPU 101 of the smart watch 1 acquires map information from the storage unit 105 (step S104). The map information acquired here is map information stored in the storage unit 105 as partial map information in the map information storage process described later, and is a display mode corresponding to the area where the current position indicated by the current position information exists. It is map information. The display mode of the acquired map information is based on the area information stored in the storage unit 105 together with the partial map information in the map information storage process described later. When the map information of the corresponding display mode is not stored in the storage unit 105, the map information of the display mode when the map information is displayed immediately before may be acquired. Further, the map information acquired here may be map information of a preset display mode regardless of the current position.

Next, the CPU 101 causes the display unit 104 to display the acquired map information and the current position information (step S105). Here, the map information displayed on the display unit 104 will be described with reference to FIG.

For example, the screen G6a shown in FIG. 6A is displayed on the display unit 104. On the screen G6a, a map within a predetermined distance range is displayed centering on the current location pin P61 indicating the current position of the user. The current location button P62, the zoom button P63, the memo type button P64, the function drawer P65, and the like are further displayed on the screen G6a. The position of the current location pin P61 on the map information is determined based on the current position information acquired in step S103.

When the display unit 104 is swiped by the user while the screen G6a is displayed, the CPU 101 scrolls the map information according to the swiping direction, and the map information around the current location pin P61, for example, FIG. 6 (b). ) Is displayed on the display unit 104. Further, when the current location button P62 is tapped by the user while the screen G6b is displayed, the CPU 101 causes the display unit 104 to display the screen G6a centered on the current location pin P61 again.

Further, when the zoom button P63 is tapped or the push button switch 102a is pressed while the screens G6a, G6b, etc. are displayed, the CPU 101 may perform an operation of enlarging or reducing the map information. A possible screen (not shown) is displayed on the display unit 104.

Further, when the memo type button P64 is tapped or the push button switch 102c is pressed by the user while the screens G6a, G6b, etc. are displayed, the CPU 101 adds an icon on the map information or maps. A screen (not shown) capable of performing an operation such as leaving memo information by voice input or the like on the information is displayed on the display unit 104.

Further, when the function drawer P65 is tapped by the user or swiped upward from the bottom of the display unit 104 while the screens G6a, G6b, etc. are displayed, the CPU 101 displays the function drawer screen (not shown). It is displayed on the display unit 104. With the function drawer screen displayed, the user can change various settings by performing a predetermined operation.

Further, when the screens G6a, G6b, etc. are displayed on the display unit 104 and no operation by the user is input for a predetermined time, the CPU 101 displays the current location button P62, the zoom button P63, the memo type button P64, and the display unit 104. The function drawer P65 may be eliminated. These various buttons P62 to P65 may be disappeared at the same time, or may be sequentially disappeared according to the elapsed time. Further, the various buttons P62 to P65 may be changed to an inconspicuous expression by lightening the color without disappearing.

As shown in FIG. 5, next, the CPU 101 of the smart watch 1 requests the current position information from the smartphone 2 by the communication unit 106 (step S106).

Next, the CPU 201 of the smartphone 2 acquires the current position information indicating the user's current position by the satellite radio wave receiving module 208, and transmits the current position information to the smart watch 1 by the communication unit 206 (step S107).

Next, the CPU 101 of the smart watch 1 acquires the current position information by the communication unit 106 (step S108). As a result, when the user moves from the time of the previous acquisition of the current position information to the time of the current acquisition of the current position information, the current location pin P61 on the display unit 104 also moves to the position corresponding to the current current position, and the current location The map information is automatically scrolled and redisplayed so that the pin P61 is located at the center of the display unit 104.

Next, the CPU 101 determines whether or not the current position indicated by the current position information acquired this time has moved from the first area to the second area (step S109). Specifically, the CPU 101 has a second area in which the current position indicated by the current position information acquired this time is different from the first area in which the current position indicated by the currently acquired current position information exists, based on the map information and the area information. Determine if you have entered the area.

When it is determined that the current position has moved from the first area to the second area (step S109; YES), the CPU 101 displays the map information displayed on the display unit 104 without changing the scale of the current position. The map information is switched to the map information of the display mode corresponding to the second area where the current position indicated by the information exists (step S110). That is, the CPU 101 acquires the map information of the display mode corresponding to the second area where the current position exists from the storage unit 105 based on the area information stored in the storage unit 105, and changes the scale of the acquired map information. It is displayed on the display unit 104 without doing so. As a result, the map information of the display mode suitable for the second area where the current position exists can be easily displayed on the display unit 104. If the map information of the display mode corresponding to the second area after movement is not stored in the storage unit 105, the CPU 101 may not switch the map information displayed on the display unit 104. A screen (not shown) prompting the execution of the map information storage process described later may be displayed on the display unit 104.

If it is determined that the current position has not moved to the second area (step S109; NO), the CPU 101 skips the process of step S110 and performs the process of step S111.

Next, the CPU 101 determines whether or not to end the display of the map information based on the user's operation (step S111). Specifically, for example, when the push button switch 102b is pressed by the user while the screens G6a, G6b, etc. shown in FIG. 6 are displayed, the CPU 101 determines that the display of the map information is finished.

If it is determined that the display of the map information is not finished (step S111; NO), the CPU 101 performs the process of step S106. That is, the CPU 101 requests the current position information from the smartphone 2 and acquires it again.

When it is determined that the display of the map information is finished (step S111; YES), the CPU 101 ends the map information display switching process.

In step S110, the map information is switched to a different display mode based only on whether or not the current position has moved from the first area to the second area, but the present invention is not limited to this.
For example, the map information may be switched to a different display mode based on the current time. More specifically, when the current position moves to the downtown area (second area) and the current time is 12:00 to 13:00, detailed map information of the display mode corresponding to the area is used. It may be switched to map information in which store information and the like are posted.

Further, for example, the map information may be switched to a different display mode based on the information input by the user. More specifically, for example, a smartwatch can be used to move a program for activities such as mountain climbing, trekking, cycling, skiing, and snowboarding by moving the current position to an area such as a mountain or highland (second area) and operating the user. When 1 is being executed, it may be switched to the map information of the display mode corresponding to the area. Further, for example, when the current position is moved to an area such as the sea or river (second area), and the smartwatch 1 is executing a program for activities such as fishing and surfing by the user's operation, the area is concerned. It may be switched to the map information of the display mode corresponding to.

Further, for example, the CPU 101 may function as an analysis means for analyzing the user's behavior, and may switch to map information having a different display mode based on the analyzed user behavior information. More specifically, the CPU 101 acquires various information such as the history of the current position, the moving distance, the moving speed, the date and time, the temperature, the humidity, the atmospheric pressure, the user's heart rate or the amount of change thereof, and based on these. Analyzes the user's behavior and acquires behavior information indicating the user's behavior. Then, for example, when the current position moves to an area such as a mountain or a highland (second area) and the user's action indicated by the action information is mountain climbing, trekking, cycling, skiing, snowboarding, or the like, the area concerned. It may be switched to the map information of the display mode corresponding to. Further, for example, when the current position moves to an area such as the sea or river (second area) and the action information is fishing, surfing, etc., the map information is switched to the display mode corresponding to the area. Is also good.

(Map information memory processing)
Subsequently, the map information storage process performed by the map information display system 100 of the present embodiment will be described with reference to FIGS. 7 to 9. FIG. 7 is a flowchart showing an example of map information storage processing according to the present embodiment. FIG. 8 is a diagram showing an example of a screen displayed on the display unit 104 when the user determines the area to be downloaded. FIG. 9 is a diagram showing an area displayed on the display unit 104 and an area downloaded as partial map information.

The map information storage process is a process of downloading the map information displayed in the map information display switching process via the smartphone 2 and storing it in the storage unit 105 of the smart watch 1. The map information storage process is performed when a predetermined operation is performed by the operation input unit 102 of the smartwatch 1 at an arbitrary timing when the user wants to store the map information in the smartwatch 1. For example, when it is assumed that the smart watch 1 cannot connect to the smartphone 2 in communication or the smartphone 2 cannot connect to the communication network N, it is preferable that the map information storage process is performed in advance.

As shown in FIG. 7, first, the CPU 101 determines whether or not the display mode of the map information to be downloaded is selected based on a predetermined operation by the user (step S201). For example, the user can select the map information of the display mode desired to be downloaded from the map information of the plurality of display modes including the example shown in FIG.

If it is determined that the map information display mode is not selected (step S201; NO), the CPU 101 ends the map information storage process.

When it is determined that the map information display mode has been selected (step S201; YES), the CPU 101 requests the smartphone 2 for the map information for viewing by the communication unit 106 (step S202).

Next, the CPU 201 of the smartphone 2 communicates with the server 3 via the communication network N by the communication unit 206, acquires the browsing map information from the browsing map information database 31 of the server 3, and acquires the browsing map information. Is transmitted to the smart watch 1 (step S203). Here, the CPU 201 acquires the current position information indicating the user's current position by the satellite radio wave receiving module 208 together with the acquisition of the map information for browsing, and based on the current position information, the current position indicated by the current position information is the center. It is preferable to acquire the map information for browsing within the predetermined distance range.

Next, the CPU 101 of the smart watch 1 acquires the map information for viewing by the communication unit 106 (step S204).

Next, the CPU 101 causes the display unit 104 to display the acquired map information for browsing (step S205). Here, the screen displayed on the display unit 104 will be described with reference to FIG.

For example, the screen G8 shown in FIG. 8 is displayed on the display unit 104. On the screen G8, the browsing map information centered on the user's current position is displayed, and the intersection P81 of the cross line displayed on the browsing map information indicates the center position (current position). Further, the current location button P82, the enlargement button P83, the reduction button P84, and the "determine map" button P95 are displayed.

When the display unit 104 is swiped by the user while the screen G8 is displayed, the CPU 101 scrolls the viewing map information according to the swiping direction, and the area displayed on the display unit 104 is the viewing map. Move on the information. As a result, the viewing map information of the area centered on the position other than the current position is displayed on the display unit 104, and the area can be set as the download range. Further, when the current location button P82 is tapped by the user while the area centered on the position other than the current position is displayed, the CPU 101 causes the area displayed on the display unit 104 to be centered on the current position. Is returned to, and the screen G8 is displayed on the display unit 104 again.

Further, when the enlargement button P83 is tapped or the push button switch 102a is pressed by the user, the CPU 101 causes the display unit 104 to display a screen (not shown) in which the map of the screen G8 is enlarged by a predetermined magnification. Similarly, when the reduction button P84 is tapped or the push button switch 102c is pressed by the user, the CPU 101 causes the display unit 104 to display a screen (not shown) in which the map of the screen G8 is reduced by a predetermined magnification. As a result, the area that is enlarged or reduced and displayed on the display unit 104 can be set as the download range.
In this way, the CPU 101 can specify an arbitrary area of the map information for browsing by the user's operation and display the area on the display unit 104.

As shown in FIG. 7, the CPU 101 next determines whether or not the download range has been determined (step S206). Specifically, for example, when the user taps the "determine map" button P95 while the screen G8 shown in FIG. 8 is displayed, the CPU 101 determines that the download range has been determined.

If it is determined that the download range is not determined (step S206; NO), the CPU 101 ends the map information storage process.

When it is determined that the download range has been determined (step S206; YES), the CPU 101 requests the smartphone 2 to download the partial map information (step S207). Specifically, the CPU 101 requests the download of partial map information, which is an area corresponding to the entire area displayed on the display unit 104 among the browsing map information. For example, when the entire area displayed on the display unit 104 is the area L1 in FIG. 9, the CPU 101 uses the rectangular area L2 including the area L1 as the partial map information. In this way, by setting an area wider than the area displayed on the display unit 104 as the download area, the user tries to confirm the slightly outside of the area L1 on the map information acquired after the map information storage process is completed. Sometimes it is not necessary to re-download, which can improve convenience. The CPU 101 may set only the entire area displayed on the display unit 104 of the browsing map information as the download area, or may be set in advance from the entire area displayed on the display unit 104. The area narrowed by that amount may be set as the download area.

In step S201, the display mode of the map information to be downloaded is selected based on a predetermined operation by the user, but the present invention is not limited to this. For example, the map information of all the downloadable display modes may be downloaded at once, and in this case, the process of step S201 may not be performed.
Further, for example, the process of step S201 may be performed after it is determined that the download range is determined by the process of step S206. In this case, the CPU 101 may acquire the area information corresponding to the determined download range and select one of the map information of the display mode included in the area information.
Further, for example, the CPU 101 does not perform the process of step S201, and after it is determined that the download range is determined by the process of step S206, the CPU 101 acquires the area information corresponding to the determined download range and uses the area information. Based on this, map information of the display mode corresponding to each area may be downloaded for each area included in the download range.

Further, in step S207, the display unit 104 is circular as shown in FIG. 1 and the like, and the rectangular region L2 including the circular region L1 shown in FIG. 9 is used as partial map information, but the information is limited to this. is not. For example, the display unit 104 may be rectangular and a circular area including the entire area displayed on the display unit 104 may be used as partial map information, or the display unit 104 may be circular or rectangular and the display unit may be displayed. The entire area displayed in 104 may be used as it is as partial map information. Further, the shape of the display unit 104 may be a shape other than a circle or a rectangle, and the partial map information may be any shape as long as it corresponds to the entire area displayed on the display unit 104. good.

Further, in step S208, the CPU 201 of the smartphone 2 communicates with the server 4 via the communication network N by the communication unit 206 to download the partial map information, but the present invention is not limited to this. For example, the CPU 201 determines whether or not data communication with the server 4 is possible by wireless communication of a method such as Wi-Fi (registered trademark), and if possible, displays a screen for switching to the Wi-Fi method. It may be displayed on 104. When the Wi-Fi method is switched to, the download time of the partial map information can be shortened, and the convenience can be further improved.

<< Modification example >>
A modified example of the map information display system 100 of the above-described embodiment will be described. The points other than those described below are assumed to be configured in the same manner as the map information display system 100 of the above embodiment.

The map information display system according to the modified example differs from the map information display system 100 of the above embodiment in the following points. That is, the map information display system according to the modified example does not include the smartphone 2, but is composed of the smart watch 1, the server 3, and the server 4. The smart watch 1 is a server by the communication unit 106 without using a smartphone or the like. It is configured to be able to send and receive data by communicating with external devices such as 3 and 4. Therefore, the map information display system according to the modified example performs various processes performed by the map information display system 100 of the above embodiment by the smart watch 1 alone. Therefore, it is sufficient for the user to have only the smart watch 1, and the smart watch 1 does not have to be in a state where data communication can be performed with the smartphone 2.

For example, the map information display system according to the modified example, that is, the smart watch 1, performs the map information display switching process and the map information storage process as follows.

(Map information display switching process)
First, the map information display switching process according to the modified example will be described with reference to FIG. FIG. 11 is a flowchart showing an example of the map information display switching process according to the modified example.

The map information display switching process is performed when a predetermined operation is performed by the operation input unit 102 of the smart watch 1 at an arbitrary timing when the user wants to view the map information.

First, as shown in FIG. 11, the CPU 101 of the smart watch 1 acquires the current position information indicating the current position of the user by the satellite radio wave receiving module 108 (step S301).

Next, the CPU 101 acquires map information from the storage unit 105 (step S302). The map information acquired here is map information stored in the storage unit 105 as partial map information in the map information storage process described later, and is a display mode corresponding to the area where the current position indicated by the current position information exists. It is map information. The display mode of the acquired map information is based on the area information stored in the storage unit 105 together with the partial map information in the map information storage process described later.

Next, the CPU 101 causes the display unit 104 to display the acquired map information and the current position information (step S303).

Next, the CPU 101 acquires the current position information indicating the user's current position by the satellite radio wave receiving module 108 (step S304).

Next, the CPU 101 determines whether or not the current position indicated by the current position information acquired this time has moved from the first area to the second area (step S305). Specifically, the CPU 101 has a second area in which the current position indicated by the current position information acquired this time is different from the first area in which the current position indicated by the currently acquired current position information exists, based on the map information and the area information. Determine if you have entered the area.

When it is determined that the current position has moved to the second area (step S305; YES), the CPU 101 displays the map information displayed on the display unit 104 without changing the scale of the current position indicated by the current position information. Switch to the map information of the display mode corresponding to the area where is present (step S306).

If it is determined that the current position has not moved to the second area (step S305; NO), the CPU 101 skips the process of step S306 and performs the process of step S307.

Next, the CPU 101 determines whether or not to end the display of the map information based on the user's operation (step S307).

If it is determined that the display of the map information is not finished (step S307; NO), the CPU 101 performs the process of step S304.

When it is determined that the display of the map information is finished (step S307; YES), the CPU 101 ends the map information display switching process.

(Map information memory processing)
Subsequently, the map information storage process according to the modified example will be described with reference to FIG. FIG. 12 is a flowchart showing an example of map information storage processing according to a modified example.

The map information storage process is performed when a predetermined operation is performed by the operation input unit 102 of the smartwatch 1 at an arbitrary timing when the user wants to store the map information in the smartwatch 1. For example, when it is assumed that the smartwatch 1 cannot connect to the communication network N, it is preferable that the map information storage process is performed in advance.

As shown in FIG. 12, first, the CPU 101 determines whether or not the display mode of the map information to be downloaded is selected based on a predetermined operation by the user (step S401).

If it is determined that the map information display mode is not selected (step S401; NO), the CPU 101 ends the map information storage process.

When it is determined that the map information display mode is selected (step S401; YES), the CPU 101 communicates with the server 3 via the communication network N by the communication unit 106, and from the map information database 31 for browsing of the server 3. Acquire the map information for browsing (step S402).

Next, the CPU 101 causes the display unit 104 to display the acquired map information for browsing (step S403).

Next, the CPU 101 determines whether or not the download range has been determined (step S404).

If it is determined that the download range is not determined (step S404; NO), the CPU 101 ends the map information storage process.

When it is determined that the download range has been determined (step S404; YES), the CPU 101 downloads the partial map information (step S405). That is, the CPU 101 communicates with the server 4 via the communication network N by the communication unit 106, and downloads and acquires the partial map information from the partial map information database 41 of the server 4. Further, the CPU 101 downloads and acquires the partial map information as well as the area information indicating the area included in the partial map information and the display mode associated with each area from the area database 42 of the server 4.

Next, the CPU 101 stores the acquired partial map information in the storage unit 105 together with the area information (step S406).

Map information storage processing is performed as described above.

(Technical effect of modified example)
As described above, according to the modified example, since the map information display system is not provided with a smartphone, not only the technical effect obtained in the above embodiment but also the convenience is significantly improved because the user does not need to possess the smartphone. be able to.

《Others》
The description in the above embodiment and the modified example is an example of a suitable map information display system according to the present invention, and is not limited thereto. In particular, the various images displayed on the display unit 104 of the smart watch 1 are examples, and the present invention is not limited to these.

For example, in the above-described modification, the map information display system includes the smartwatch 1, the server 3, and the server 4, but the present invention is not limited to this. That is, the map information display system may not include the smartwatch 1 but may include a smartphone 2, a server 3, and a server 4. In this case, the smartphone 2 independently performs various processes such as the map information display switching process and the map information storage process described above.

Further, in the above-described embodiment, the time limit per cycle of the processes of steps S106 to S111 is not particularly set in the map information display switching process, but the time limit is not limited to this. For example, the setting may be changed so that the CPU 101 acquires the current position information every 1 second, every 5 seconds, every 60 seconds, etc. based on the user's operation. By setting this time limit short, the accuracy of the current position can be improved, and by setting the time limit long, the battery consumption of the smartwatch 1 can be reduced. Further, for example, when the CPU 101 of the smart watch 1 is executing a program for activities such as mountain climbing, trekking, cycling, skiing, snowboarding, fishing, and surfing, the time limit is set according to those activities. May be.

Further, in the above-described embodiment, when the current position is included in the first area, the map information of the display mode corresponding to the first area is displayed on the display unit 104, and the current position is the second area. When the map information of the display mode corresponding to the second area is displayed on the display unit 104, that is, the automatic switching mode has been described, but the present invention is not limited to this. For example, in addition to the automatic switching mode, the CPU 101 manually switches between displaying the map information in the display mode corresponding to the first area and displaying the map information in the display mode corresponding to the second area. The manual switching mode may be performed. In the manual switching mode, it may be possible to switch only to the map information of the display mode stored in the storage unit 105 in advance, or the operation of switching to the map information of the display mode other than the display mode stored in the storage unit 105 is performed. In this case, a screen (not shown) prompting the execution of the map information storage process may be displayed on the display unit 104. Further, for example, the automatic switching mode and the manual switching mode may be appropriately switched based on the setting operation by the user, or in the state of being set to the automatic switching mode, the first area may be set. The display of the map information in the corresponding display mode and the display of the map information in the display mode corresponding to the second area may be switched manually by the user.

Further, in the above-described embodiment and modification, when the current position moves from the first area to the second area, the map information is switched to the map information of the display mode corresponding to the second area where the current position exists. However, it is not limited to this.
For example, the CPU 101 causes the display unit 104 to display composite map information in which the map information of the display mode associated with the first area and the map information of the display mode associated with the second area are linked. It may be a thing. Specifically, the CPU 101 generates composite map information displayed in a display mode corresponding to the area for each area based on the area database 42 of the server 4, and displays the generated composite map information on the display unit 104. It may be made to do. Here, the composite map information is map information in which a plurality of map information of display modes associated with each area are linked and displayed in different display modes for each area. As a result, it is possible to obtain map information of a display mode suitable for each land. Further, in this case, when the current position moves from the first area to the second area, the map information is not switched to the map information of the display mode corresponding to the second area where the current position exists, but the composite map information. May be provided to the user at all times. Therefore, the timing for displaying the composite map information may be, for example, when the map information is displayed on the display unit 104 (for example, the timing of step S105 of the map information display switching process shown in FIG. 5). It may be when the current position moves from the first area to the second area and the map information is switched (for example, the timing of step S110 of the map information display switching process shown in FIG. 5). Further, after displaying the composite map information on the display unit 104, it is not necessary to switch to the map information of another display mode.

Further, the CPU 101 determines a display mode of map information for each area based on predetermined conditions, for example, time information, information input by a user, and the like, and generates composite map information based on the determined display mode. It may be something to do. Specifically, for example, when the time information indicating the time at the time of generating the composite map information or the time information input by the user's operation indicates a time zone within a predetermined range, the map information is according to the time zone. The display mode of the above may be selected and determined for each area, and the composite map information may be generated based on this. Further, for example, when the CPU 101 is executing a program for activities such as mountain climbing, trekking, cycling, skiing, snowboarding, fishing, and surfing by a user's operation, the map information display mode is changed according to those activities. It may be selected and determined for each area, and composite map information may be generated based on this. In these cases, it is possible to generate composite map information that is more suitable for the situation in which the user is placed, and it is possible to improve convenience.
Further, the generation of the composite map information by the CPU 101 may be performed, for example, when the user selects to acquire the composite map information. In this case, for example, after the download area is determined in the same manner as in steps S202 to S206 of the map information storage process, the display mode of the map information is determined for each area included in the download area, and the map information is displayed in the download area. Map information of the corresponding display mode may be acquired for each included area.
Further, the composite map information may be stored in the storage unit 105 in advance, and the CPU 101 may acquire the information from the storage unit 105 and display it.

Further, in the above-described embodiment and modification, the CPU 101 acquires the map information from the storage unit 105 and displays it (for example, steps S104 and S105 of the map information display switching process shown in FIG. 5). It is not limited to. For example, the CPU 101 may request and acquire the map information for viewing from the smartphone 2 and display it on the display unit 104. That is, the CPU 101 is not limited to the map information storage process, and may request and acquire the map information for browsing according to the operation of the user and display it on the display unit 104. Further, for example, when the map information can be acquired from the storage unit 105 and the map information for viewing can be acquired from the smartphone 2, the CPU 101 may acquire the map information from the storage unit 105. As a result, the display speed of the map information on the display unit 104 and the responsiveness of the operation by the user can be improved as compared with acquiring and displaying the map information for viewing from the smartphone 2, and the communication with the smartphone 2 is performed. Power consumption can be suppressed.

Further, in the above-described embodiment and modification, the CPU 101 or the CPU 201 acquires the browsing map information from the browsing map information database 31 and the partial map information from the partial map information database 41, but this is limited to this. It is not something that can be done. For example, the CPU 101 or the CPU 201 may acquire the browsing map information and the partial map information from the same external database.

Further, in the above-described embodiment and modification, the CPU 101 is supposed to display the partial map information stored in the storage unit 105 on the display unit 104, but the present invention is not limited to this. For example, the CPU 101 may display the partial map information on the display unit 204 of the smartphone 2 or other display devices.

Further, in the above-described embodiment and modification, the CPU 201 of the smartphone 2 acquires the current position information indicating the current position of the user by the satellite radio wave receiving module 208, or the CPU 101 of the smart watch 1 uses the satellite radio wave receiving module 108 of the user. Although the current position information indicating the current position is acquired, the present position information is not limited to this, and it is of course possible to acquire the current position information by using the network position information such as indoor location technology. ..

Further, in the above-described embodiment, an example in which a hard disk, a non-volatile memory of a semiconductor, or the like is used as a computer-readable medium of the program according to the present invention has been disclosed, but the present invention is not limited to this example. As another computer-readable medium, a portable recording medium such as a CD-ROM can be applied.
