Abstract

A terminal device having a dual touch screen capable of controlling a content is disclosed. The terminal device displays at least one content to a display unit. A processor coupled to the terminal is configured to checking content mapped to an area at which a touch event is detected and released from the dual touch screen including a first touch sensor and a second touch sensor and to control the content according to the touch event.

Claims

1. A method, comprising:

receiving a touch event from a touch screen of a display unit comprising a first touch sensor and a second touch sensor formed at a front side and/or a rear side of the display unit, wherein a content is displayed;

detecting the touch event applied from the first touch sensor and/or the second touch sensor, and checking an area at which the touch event is detected and released, the area is mapped to the content; and

controlling the content according to the touch event.

2. The method of claim 1, further comprising:

performing a function associated with the content in response to detection of the touch event from the first touch sensor; and

displaying detailed information associated with the content in response to detection of the touch from the second touch sensor.

3. The method of claim 1, further comprising:

determining whether a first area, corresponding to a first contact detected from the first touch sensor, is matched to a second area corresponding to a second contact detected from the second touch sensor;

determining whether movements of the first contact and the second contact are detected; and

changing a position of the content according to moving directions of the first contact and the second contact.

4. The method of claim 3, wherein the change of the position of the content further comprises:

deleting the content according to the moving directions.

5. The method of claim 3, wherein the determining whether the movements of the first contact and the second contact are detected comprises determining duration of time for which the first contact and the second contact are maintained, wherein zooming in or zooming out the content is performed according to the duration of time.

6. The method of claim 3, wherein the determining whether movements of the first contact and the second contact are detected comprises determining sizes of the first area and the second area, wherein zooming in or zooming out the content is performed according to sizes of the first area and the second area.

7. The method of claim 3, further comprising:

determining whether at least one of the first contact or the second contact moves in response to detection of the first area that is not matched to the second area; and

controlling a size of the content according to the movements.

8. The method of claim 7, wherein the control the size of the content comprises:

checking a distance between the first contact and the second contact according to the movements;

enlarging the size of the content in response to detection of the distance value that is greater than about 0 (zero); and

reducing the size of the content in response to detection of the distance that is approaching to about 0 (zero).

9. The method of claim 7, further comprising:

rotating the content according to movement of at least one of the first contact or the second contact in response to detection of the movement.

10. The method of claim 1, wherein the content comprises a menu icon to select a function, a multimedia icon to reproduce moving picture data and music data, an image, a thumbnail, and a data name set by data types, and wherein the touch event comprises a move event, a rotate event, a hold event and a combination at least one of the touch, move, hold or rotate event.

11. A terminal device comprising:

a touch screen comprising a display unit to display a content;

a first touch sensor formed at one side of the display unit and a second touch sensor formed at the other side of the display unit, wherein the touch screen is configured to detect a touch event via the first touch sensor and/or the second touch sensor; and

a control unit to check an area, mapped to a content, at which the touch event is detected and released from the first touch sensor and/or the second touch sensor, and to control the content according to the touch event.

12. The terminal device of claim 11, wherein the control unit is configured to cause performing a function relating to the content in response to detection of the touch event from the first touch sensor, and to control the display unit to display detailed information relating to the content in response to the touch event from the second touch sensor.

13. The terminal device of claim 11, wherein the control unit is configured to control the content according to whether a first area, at which a first contact is detected from the first touch sensor, is matched to a second area at which a second contact is detected from the second touch sensor.

14. The terminal device of claim 13, wherein the control unit is configured to determine whether the first contact and the second contact move in response to detection of the first area that is matched to the second area, and to control the display unit to change a position of the content according to moving directions of the first contact and the second contact in response to detection of movements of the first contact and the second contact.

15. The terminal device of claim 14, wherein the control unit is configured to control the display unit to zoom in or zoom out the content according to time duration at which the first contact and the second contact are maintained.

16. The terminal device of claim 14, wherein the control unit is configured to control the display unit to zoom in or zoom out the content according to sizes of the first area and the second area.

17. The terminal device of claim 13, wherein the control unit is configured to determine whether one of the first contact and the second contact moves in response to detection of the first area that is not matched to the second area, and to control a size of the content according to movement of at least one of the first contact or the second contact in response to detection of movements of the first contact and the second contact.

18. The terminal device of claim 17, wherein the control unit is configured to check a distance between the first contact and the second contact according to the movement and to control the display unit to enlarge the size of the content in response to detection of the distance value that is greater than about 0 (zero) and to reduce the size of the content in response to detection of the distance is approaching to about 0 (zero).

19. The terminal device of claim 17, wherein the control unit is configured to control the display unit to rotate and display the rotated content in response to detection one of the first contact and the second contact is fixed and the other one of the first contact and the second contact moves based on the fixed contact.

20. The terminal device of claim 11, wherein the content comprises a menu icon to select a function, a multimedia icon to reproduce moving picture data and music data, an image, a thumbnail, and a data name set by data types, and wherein the touch event comprises a move event, a rotate event, a hold event and a combination at least one of the touch, move, hold or rotate event.
