Abstract

A method and an apparatus for operating a displayed area of an electronic map and a recording medium are provided. In the method, a displayed area of an electronic map is displayed first. Then, an indicating object of a point of interest (POI) located outside the displayed area is displayed on an edge of the displayed area towards a direction of the POI with respect to the displayed area. When the indicating object of the POI is selected, the displayed area of the electronic map is changed to the displayed area comprising the POI. Accordingly, users are able to quickly change the displayed area and check a location and related information of each POI in a simple operation manner.

Claims

1. A method for operating a displayed area of an electronic map, comprising:

displaying a displayed area of an electronic map;

displaying an indicating object of a first point of interest (POI) located outside the displayed area on an edge of the displayed area towards a first direction of the first POI with respect to the displayed area; and

changing the displayed area of the electronic map to the displayed area comprising the first POI when the indicating object of the first POI is selected.

2. The method according to claim 1, wherein the originally displayed area of the electronic map comprises a second POI.

3. The method according to claim 2, wherein after the step of changing the displayed area of the electronic map to the displayed area comprising the first POI, the method further comprises:

displaying an indicating object of the second POI on an edge of the displayed area comprising the first POI towards a second direction of the second POI with respect to the first POI.

4. The method according to claim 1, wherein the step of changing the displayed area of the electronic map to the displayed area comprising the first POI is in a sliding or switching manner.

5. The method according to claim 1, wherein the step of changing the displayed area of the electronic map to the displayed area comprising the first POI comprises:

displaying the displayed area of the electronic map by taking the first POI as a center.

6. The method according to claim 1, wherein the step of changing the displayed area of the electronic map to the displayed area comprising the first POI comprises:

displaying the displayed area of the electronic map on the same scale.

7. The method according to claim 1, wherein the step of changing the displayed area of the electronic map to the displayed area comprising the first POI comprises:

displaying the displayed area of the electronic map on the same scale and taking the first POI as a center.

8. The method according to claim 1, wherein the step of changing the displayed area of the electronic map to the displayed area comprising the first POI comprises:

adjusting the scale of the displayed area of the electronic map and changing the displayed area of the electronic map, such that the changed displayed area comprises both of the first POI and the second POI.

9. The method according to claim 1, wherein the indicating object comprises one of an indicating text, an indicating symbol, and an indicating icon, or a combination thereof.

10. The method according to claim 1, wherein the indicating object is presented in a semitransparent or animation visual effect.

11. A recording medium, executing the method for operating a displayed area of an electronic map according to claim 1 via an electronic device.

12. An apparatus for operating a displayed area of an electronic map, comprising:

an input unit, for receiving an input signal;

a storage unit, for storing an electronic map;

a display unit, for displaying a displayed area of the electronic map; and

a processing unit, coupled to the input unit, the storage unit, and the display unit, and used for displaying an indicating object of a first point of interest (POI) located outside the displayed area on an edge of the displayed area displayed by the display unit towards a first direction of the first POI with respect to the displayed area;

determining whether the indicating object of the first POI is selected according to the input signal; and

changing the displayed area of the electronic map displayed by the display unit to the displayed area comprising the first POI when the indicating object of the first POI is selected.

13. The apparatus according to claim 12, wherein the displayed area of the electronic map originally displayed by the display unit comprises a second POI.

14. The apparatus according to claim 13, wherein the processing unit further displays an indicating object of the second POI on an edge of the displayed area comprising the first POI towards a second direction of the second POI with respect to the first POI.

15. The apparatus according to claim 12, wherein the display unit changes the displayed area of the electronic map to the displayed area comprising the first POI in a sliding or switching manner.

16. The apparatus according to claim 12, wherein the processing unit controls the display unit to display the displayed area of the electronic map on the same scale and take the first POI as a center.

17. The apparatus according to claim 12, wherein the processing unit adjusts the scale of the displayed area of the electronic map and changes the displayed area of the electronic map, such that the changed displayed area displayed by the display unit comprises both of the first POI and the second POI.

18. The apparatus according to claim 12, wherein the indicating object comprises one of an indicating text, an indicating symbol, and an indicating icon, or a combination thereof.

19. The apparatus according to claim 18, wherein the indicating icon comprises an arrow pointing to the first direction.

20. The apparatus according to claim 18, wherein content of the indicating text comprises one of a name of the first POI and a distance between the first POI and the second POI, or a combination thereof.
