Abstract

According to an embodiment of the present invention, a method for operating an image display device using a pointing device includes displaying, on a display of the image display device, a handwriting region, receiving a pointing signal from the pointing device, determining whether a location of an image based on positional information corresponding to the received pointing signal is included in the handwriting region, and displaying the image corresponding to the received pointing signal at a boundary area of the handwriting region closest to the location when the location of the image is determined to be not included in the handwriting region.

Claims

1. A method for operating an image display device using a pointing device, the method comprising:

displaying, on a display of the image display device, a handwriting region;

receiving a pointing signal from the pointing device;

determining whether a location of an image based on positional information corresponding to the received pointing signal is included in the handwriting region; and

displaying the image corresponding to the received pointing signal at a boundary area of the handwriting region closest to the location when the location of the image is determined to be not included in the handwriting region.

2. The method according to claim 1, further comprising:

resealing the image to fit within the handwriting region and displaying the resealed image in the handwriting region when the location of the image is determined to be not included in the handwriting region.

3. The method according to claim 1, further comprising:

displaying the image at a particular region of the handwriting region according to the positional information when the location of the image is determined to be included in the handwriting region.

4. The method according to claim 1, further comprising:

determining whether a trajectory of the image associated with the received pointing signal corresponds to a particular image;

collecting information associated with the particular image when the trajectory is determined to be corresponding to the particular image; and

displaying the collected information in a list region of the display,

wherein the list region is different from the handwriting region.

5. The method according to claim 4, wherein the particular image includes a specific character, a part of a specific character or a string of characters.

6. A method for operating an image display device using a pointing device, the method comprising:

displaying, on a display of the image display device, a handwriting region;

receiving a pointing signal from the pointing device;

determining whether or not a pointing signal trajectory corresponds to a specific character; and

displaying a list of operations associated with the specific character on an area adjacent to the handwriting region when the pointing signal trajectory is determined to correspond to the specific character.

7. The method according to claim 6, further comprising:

determining whether a location of a pointer associated with the pointing signal trajectory corresponds to inside of the handwriting region based on positional information; and

displaying a first pointer moving at a first movement speed according to the pointing signal when the location is determined to be outside of the handwriting region, or

displaying a second pointer moving at a second movement speed according to the pointing signal when the location is determined to be inside the handwriting region.

8. The method according to claim 7, wherein the second movement speed is less than the first movement speed.

9. The method according to claim 7, wherein the second pointer has a different shape from the first pointer.

10. The method according to claim 7, further comprising:

transmitting a signal allowing an output of a vibration to the pointing device or outputting an effect sound when the first pointer has been removed and the second pointer has been displayed.

11. The method according to claim 6, further comprising:

performing an operation from the list of operations associated with the specific character in response to a selection signal.

12. The method according to claim 6, wherein the pointing signal trajectory is a trajectory of discontinuously received pointing signals as long as a combination of the trajectory of the discontinuously received pointing signals forms the specific character.

13. A method for operating an image display device using a pointing device, the method comprising:

displaying, on a display of the image display device, a handwriting region;

determining whether or not a pointing signal trajectory on the handwriting region corresponds to at least a part of multiple characters;

displaying a list of operations associated with the multiple characters on an area adjacent to the handwriting region when the pointing signal trajectory corresponds to the at least part of multiple characters; and

updating the list of operations on the area adjacent to the handwriting region as the pointing signal trajectory changes.

14. The method according to claim 13, further comprising:

performing an operation from the list of operations associated with the at least part of multiple characters in response to a selection signal.

15. The method according to claim 13, wherein the pointing signal trajectory is a trajectory of discontinuously received pointing signals as long as a combination of the trajectory of the discontinuously received pointing signals forms the at least part of multiple characters.

16. The method according to claim 13, further comprising:

determining whether a location of a pointer associated with the pointing signal trajectory corresponds to inside of the handwriting region based on positional information; and

displaying a first pointer moving at a first movement speed when the location is determined to be outside of the handwriting region, or

displaying a second pointer moving at a second movement speed when the location is determined to be inside the handwriting region.

17. The method according to claim 16, wherein the second movement speed is less than the first movement speed.

18. The method according to claim 16, wherein the second pointer has a different shape from the first pointer.

19. The method according to claim 16, further comprising:

transmitting a signal allowing an output of a vibration to the pointing device or outputting an effect sound when the first pointer has been removed and the second pointer has been displayed.
