Abstract

A method for providing road guidance information includes displaying supplemental local area information in response to a prompt by a user on a map displayed for road guidance. In another method, the method includes receiving an information request for supplemental local area information, selecting supplemental local area information conforming to the information request among obtained local area information, and displaying the selected local area information on a map for road guidance. An apparatus for providing road guidance information includes a display device, a detector configured to detect a current location of the apparatus, a storage unit storing map data, and a controller configured to read out a region from the stored map data, and to display the region on the display device as a road guidance map. The controller further displays supplemental local area information on the road guidance map in response to an external request.

Claims

1. A method for providing road guidance information, the method comprising:

displaying supplemental local area information in response to a prompt by a user on a map displayed for road guidance.

2. The method of claim 1, wherein the displaying supplemental local area information includes:

selecting one of a plurality of supplemental local area information filters; and

displaying the one supplemental local area information filter on the map display.

3. The method of claim 2, wherein the displaying supplemental local area information includes:

selecting a second of the plurality of supplemental local area information filters; and

replacing the one supplemental local area information filter displayed previously on the map with the second local area information filter is displayed instead thereof.

4. The method of claim 2, wherein the displaying supplemental local area information includes:

selecting a second of the plurality of supplemental local area information filters; and

overlaying the second of the plurality of supplemental local area information filters on the one local area information filter displayed previously on the map.

5. The method of claim 2, wherein the plurality of supplemental local area information filters contain categorized local area information differentiated from each other.

6. The method of claim 1, wherein the displaying supplemental local area information includes:

overlaying a plurality of supplemental local area information filters on the map display.

7. The method of claim 1, wherein the displaying supplemental local area information includes:

receiving the supplemental local area information from a remote place through a network.

8. The method of claim 1, further comprising:

inputing a condition for the supplemental local area information; and

removing supplemental local area information not conforming to the input condition from the displayed supplemental local area information.

9. The method of claim 8, wherein the input condition is a code constituting a character, and removing supplemental local area information includes:

comparing the code to character strings for the supplemental local area information and removing the supplemental local area information when the character string is not in the same placement order as the input code.

10. The method of claim 1, wherein a path for road guidance is displayed on the map.

11. The method of claim 1, further comprising:

detecting a current location of the user; and

displaying objects on the map display including at least roads.

12. A method for providing road guidance information, comprising:

receiving an information request for supplemental local area information;

selecting supplemental local area information conforming to the information request among obtained local area information; and

displaying the selected supplemental local area information on a map for road guidance.

13. The method of claim 12, wherein the selected supplemental local area information is selected from a plurality of local area information filters.

14. The method of claim 12, wherein the information request is a code constituting a character, and selecting supplemental local area information includes:

comparing the code to character strings for the supplemental local area information; and

returning the supplemental local information when the character string is in the same placement order as the input code.

15. The method of claim 14, further comprising:

detecting a current location of the user; and

displaying objects on the map display including at least roads.

16. An apparatus for providing road guidance information comprising:

a display device;

a detector configured to detect a current location of the apparatus;

a storage unit storing map data; and

a controller configured to read out a region from the stored map data, the region being associated with the detected current, and to display the region on the display device as a road guidance map,

the controller further configured to display supplemental local area information on the road guidance map in response to an external request.

17. The apparatus of claim 16, wherein the supplemental local area information is either stored in the apparatus or obtained from an external device via a network.

18. The apparatus of claim 16, wherein the controller, based on the map data, is configured to search for a path to reach a destination designated by a user and to display the path found from the search on the road guidance map displayed on the display device.

19. The apparatus of claim 16, wherein the displayed supplemental local area information belongs to at least one of a plurality of supplemental local area information filters.

20. The apparatus of claim 16, wherein the displayed supplemental local area information is selected information conforming to an information request for supplemental local area information.

21. The apparatus of claim 20, wherein the information request is a code constituting a character, and the supplemental local area information is selected information where a character string for the supplemental local area information is in the same placement order as the input code.

22. The apparatus of claim 16, wherein the road guidance map displays objects including at least roads.
