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;

displaying a pointer on the pointing signal;

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

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; and

transmitting a signal allowing an output of a vibration to the pointing device or outputting an effect sound when the pointer is moved from outside of the handwriting region to inside the handwriting region or from inside of the handwriting region to outside the handwriting region.

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

rescaling the image to fit within the handwriting region and displaying the rescaled 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, wherein the pointing signal includes information about movement of the pointing device, and

wherein the pointing signal is wirelessly received through an RF module.

5. 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.

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

7. 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;

displaying a pointer based on the pointing signal;

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

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; and

transmitting a signal allowing an output of a vibration to the pointing device or outputting an effect sound when the pointer is moved from outside of the handwriting region to inside the handwriting region or from inside of the handwriting region to outside the handwriting region.

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

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

9. The method according to claim 7, 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.

10. The method according to claim 7, wherein the pointing signal includes information about movement of the pointing device, and

wherein the pointing signal is wirelessly received through an RF module.

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

determining whether a location of the 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.

12. The method according to claim 11, wherein the second movement speed is less than the first movement speed.

13. The method according to claim 11, wherein the second pointer has a different shape from the first pointer.

14. 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;

displaying a pointer based on the pointing signal;

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;

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

transmitting a signal allowing an output of a vibration to the pointing device or outputting an effect sound when the pointer is moved from outside of the handwriting region to inside the handwriting region or from inside of the handwriting region to outside the handwriting region.

15. The method according to claim 14, 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.

16. The method according to claim 14, 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.

17. The method according to claim 14, wherein the pointing signal includes information about movement of the pointing device, and

wherein the pointing signal is wirelessly received through an RF module.

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

determining whether a location of the 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.

19. The method according to claim 18, wherein the second movement speed is less than the first movement speed.

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