Abstract

Provided are a method and apparatus for searching for a target location using a reference point and a relative location in relation to the reference point, the method comprising receiving a reference point related to the target location; receiving relative location information relating to from the reference point to the target location; and then searching for the target location based on the reference point and the relative location information.

Claims

1. A method of searching for a target location, the method comprising:

receiving a reference point related to the target location;

receiving relative location information relating to location relationships between the reference point and the target location; and

searching for the target location based on the reference point and the relative location information.

2. The method of claim 1, wherein the receiving of the relative location information comprises:

requesting input of the relative location information; and

receiving the relative location information corresponding to the request.

3. The method of claim 2, wherein in the requesting of the input of the relative location information, a relative location information list, in which detailed items representing the relative location information are listed, is output, and

in the receiving of the relative location information, at least one of the detailed items is received as the relative location information corresponding to the output relative location information list.

4. The method of claim 3, further comprising managing the relation location information list for at least one of addition, modification, and deletion of the detailed items included in the relative location information list.

5. The method of claim 1, wherein the relative location information is at least one of direction information from the reference point to the target location and distance information from the reference point to the target location.

6. The method of claim 5, wherein the direction information to the target location includes at least one of ‘

left’

, ‘

right’

, ‘

make a left’

, ‘

make a right’

, and ‘

opposite to’

, and

the distance information to the target location includes at least one of ‘

100 m’

‘

200 m’

, and ‘

one block’

.

7. The method of claim 1, wherein the relative location information includes first relative location information and second relative location information, and the searching for the target location comprises:

searching for a first target location based on the reference point and the first relative location information; and

searching for a final target location based on the first target location and the second relative location information.

8. The method of claim 1, wherein the method of searching for target location is performed in a navigation device of a mobile terminal to guide a user of the mobile terminal.

9. The method of claim 1, wherein the location relationships correspond to information from the reference point to the target location.

10. An apparatus of searching for a target location, comprising:

an interface unit which receives a reference point related to the target location and relative location information relating to the location relationships between the reference point and the target location; and

a target location searching unit which searches for the target location based on the reference point and the relative location information.

11. The apparatus of claim 10, further comprising an output unit which requests input of the relative location information,

wherein the interface unit receives the relative location information corresponding to the request of the output unit.

12. The apparatus of claim 11, wherein the output unit outputs a relative location information list in which detailed items representing the relative location information are listed, and

the interface unit receives at least one of the detailed items as the relative location information.

13. The apparatus of claim 12, further comprising a list manager which manages at least one of addition, modification, and deletion of the detailed items included in the relative location information list.

14. The apparatus of claim 10, wherein the relative location information is at least one of direction information from the reference point to the target location and distance information from the reference point to the target location.

15. The apparatus of claim 14, wherein the direction information to the target location includes at least one of ‘

left’

, ‘

right’

, ‘

make a left’

, ‘

make a right’

, and ‘

opposite to’

, and

the distance information to the target location includes at least one of ‘

100 m’

, ‘

200 m’

, and ‘

one block’

.

16. The apparatus of claim 10, wherein the relative location information includes first relative location information and second relative location information, and the searching for the target location comprises:

searching for a first target location based on the reference point and the first relative location information; and

searching for a final target location based on the first target location and the second relative location information.

17. The apparatus of claim 10, wherein the apparatus is in a navigation device of a mobile terminal to guide a user of the mobile terminal.

18. The apparatus of claim 10, wherein the relative location information corresponds to location relationships between the reference point and the target location.

19. A computer readable medium storing a computer program performing a method of searching for a target location, the method comprising:

receiving a reference point related to the target location;

receiving relative location information relating to location relationships between the reference point and the target location; and

searching for the target location based on the reference point and the relative location information.
