Abstract

Provided are a display apparatus and method for recognizing locations. The display apparatus recognizes a location, and communicates with an external device having a tag reader. The display apparatus includes a display unit; a plurality of tags disposed on the display unit, each tag having a different identification (ID); a location information storage unit in which location information of each tag is stored; and a control unit which determines a location of the external device by comparing the ID with the location information stored in the location information storage unit, if the tag ID recognized by the external device is received from the external device.

Claims

1. A display apparatus which recognizes a location and communicates with an external device having a tag reader, the display apparatus comprising:

a display unit;

a plurality of tags disposed on the display unit, each of the tags having a different identification (ID);

a location information storage unit in which location information of each of the tags is stored; and

a control unit which determines a location of the external device by comparing an ID with the location information stored in the location information storage unit, if a tag ID recognized by the external device is received from the external device.

2. The display apparatus of claim 1, wherein the tags are disposed in at least one of a front side and a rear side of the display unit.

3. The display apparatus of claim 1, wherein if a plurality of IDs are received, the control unit determines a center location between corresponding tags as a location of the external device, based on the plurality of IDs and location information stored in the location information storage unit.

4. The display apparatus of claim 1, further comprising a communication unit which communicates with the external device via at least one of wired communication and wireless communication.

5. The display apparatus of claim 1, wherein the display unit comprises a touch screen panel which senses an input by a user.

6. The display apparatus of claim 5, wherein if an ID is received from the external device and the touch screen panel senses at least one input, the control unit determines a location of a corresponding tag based on the received ID and location information stored in the location information storage unit, and determines a location closest to the external device as a location of the external device.

7. The display apparatus of claim 6, wherein if a plurality of IDs are received, the control unit determines a center location between corresponding tags based on the plurality of IDs and the location information stored in the location information storage unit, and determines a location closest to the center location as a location of the external device.

8. The display apparatus of claim 5, further comprising a communication unit which communicates with the external device via at least one of wired communication and wireless communication.

9. The display apparatus of claim 6, wherein the control unit determines a direction of the external device at the determined location of the external device, based on location information sensed by the touch screen.

10. The apparatus of claim 1, further comprising:

a tag writer which records predetermined information in the plurality of tags; and

a tag antenna through which communication is established between each of the tags and the tag writer.

11. A display apparatus which recognizes a location and communicates with an external device having a tag reader, the display apparatus comprising:

a display unit;

a plurality of tags disposed on the display unit, each of the tags having different location information; and

a control unit which determines a location of the external device, based on location information, if the location information of the tags recognized by the external device is received from the external device.

12. The display apparatus of claim 11, wherein the tags are disposed in at least one of a front side and a rear side of the display unit.

13. The display apparatus of claim 11, wherein the display unit comprises a touch screen panel which senses an input by a user.

14. The display apparatus of claim 13, wherein if the location information is received from the external device and the touch screen panel senses at least one input, the control unit determines a location of a corresponding tag based on the received location information, and determines a location closest to the location of the corresponding tag as a location of the external device.

15. A method of recognizing a location of an external device having a tag reader, the method comprising:

receiving an identification (ID) recognized by the external device; and

determining a location of the external device, based on the received ID and location information of the ID.

16. The method of claim 15, wherein the determining the location of the external device comprises:

if a plurality of IDs are received, determining a center location between corresponding tags based on the plurality of IDs and the location information of the plurality of IDs, and determining the center location as the location of the external device.

17. A method of recognizing an external device having a tag reader, the method comprising:

sensing an input by using a display unit having a touch screen panel;

receiving an identification (ID) recognized by the external device; and

determining a location of a corresponding tag based on the received ID and the location information of the ID, and determining a location closest to the corresponding tag from among location coordinates sensed by the touch screen as the location of the external device.

18. The method of claim 17, wherein the determining comprises:

if a plurality of IDs and location information are received, determining a center location between corresponding tag coordinates based on the plurality of IDs and the location information of the plurality of IDs;

mapping location coordinates sensed by the touch screen closest to the center location of the tag coordinates; and

determining the mapped coordinates as a location of the external device.

19. An apparatus for communicating with an external device having a tag reader, the apparatus comprising:

a display unit;

a plurality of tags disposed on the display unit;

a tag writer which records predetermined information in the plurality of tags, wherein the predetermined information includes location information; and

a control unit which determines a location of the external device according to the predetermined information, if the external device recognizes the predetermined information and the predetermined information is received from the external device.

20. The apparatus of claim 19, wherein the tags are located in a rear side of the display unit.

21. The apparatus of claim 19, further comprising a tag antenna through with communication is established between each of the tags and the tag writer.

22. The apparatus of claim 21, wherein the tag writer and the tag antenna are located on a rear side of the display unit.

23. The apparatus of claim 19, wherein the predetermined information comprises text information.

24. A method of recognizing a location of an external device having a tag reader, the method comprising:

if predetermined information is displayed on a display unit, recording the predetermined information and location information of the predetermined information in a tag;

receiving the predetermined information and the location information from the external device if the external device recognizes the predetermined information and location information; and

determining the location of the external device based on the received predetermined information and location information.

25. The method of claim 24, wherein the recording of the predetermined information and the location information comprises recording the predetermined information and the location information in a tag via a tag antenna if the predetermined information is displayed on the display unit.
