Abstract

An apparatus and method for providing a user interface for interacting to various touch events detected by multiple touch sensors formed on the different surfaces of a mobile terminal are provided. The method, for a mobile terminal having a first touch area and a second touch area, includes detecting a touch event that includes a first touch sensed on the first touch area and a second touch sensed on the second touch area, identifying a movement pattern of the touch event, and providing a user interface in accordance with the movement pattern. The apparatus and method for providing a user interface according to the present invention is advantageous to input various user commands intuitively using multi-touch gestures and improve utilization of the mobile terminal with enriched emotional expressions.

Claims

1. A method for providing a user interface in a mobile terminal having a first touch area and a second touch area that are formed on opposite surfaces, the method comprising:

detecting a touch event that includes a first touch sensed on the first touch area and a second touch sensed on the second touch area;

identifying a movement pattern of the touch event; and

providing a user interface in accordance with the movement pattern.

2. The method of claim 1, wherein the movement pattern comprises at least one of an opposite direction movement pattern in which the first and second touches move in opposite directions, a same direction movement pattern in which the first and second touches move in the same direction, and a single touch movement pattern in which one of the first and second touches moves in a direction while the other stays at a position.

3. The method of claim 1, wherein the movement pattern comprises at least one of a vertical movement pattern in which at least one of the first and second touches moves up and down, a horizontal movement pattern in which at least one of the first and second touches moves left and right, and a circular movement pattern in which at least one of the first and second touches move circularly.

4. The method of claim 2, further comprising:

executing a plurality of applications and content items before the detecting of the touch event; and

displaying an execution window of one of the plurality of applications and content items in response to the touch event.

5. The method of claim 4, wherein the providing of the user interface comprises:

displaying the execution windows of the plurality of applications and content items in overlapped manner at a regular distance in accordance with a direction and speed of the movement pattern.

6. The method of claim 4, wherein the providing of the user interface comprises:

displaying the execution windows of the plurality of applications and content items in overlapped manner at a regular distance in accordance with a direction and distance of the movement pattern;

determining whether the distance of the movement pattern is greater than a threshold value; and

displaying, if the distance of the movement pattern is greater than a threshold value, the execution windows at a fixed interval.

7. The method of claim 2, further comprising:

locking a screen of the mobile terminal by activating a screen lock function before the detecting of the touch event,

wherein the providing of the user interface comprises unlocking the locked screen in response to the touch event.

8. The method of claim 2, further comprising:

playing a music file before the detecting of the touch event,

wherein the proving of the user interface comprises adjusting the volume of the music file being played in response to the touch event.

9. The method of claim 2, further comprising:

displaying a picture before the detecting of the touch event.

10. The method of claim 9, wherein the providing of the user interface comprises one of zooming in and out the picture in response to the touch event.

11. The method of claim 9, wherein the providing of the user interface comprises:

rotating the picture in accordance with the direction of the movement pattern of the touch event.

12. The user method of claim 9, wherein the providing of the user interface comprises:

moving, when the movement pattern is made only with movement of the touch on the first touch area, the picture in accordance with the direction of the movement; and

zooming, when the movement pattern is made only with movement of the touch on the second touch area, the picture in accordance with the direction of the movement.

13. The method of claim 9, wherein the picture comprises a 3-dimensional picture and the providing of the user interface comprises:

moving, when the movement pattern is made only with movement of the touch on the first area, the picture in accordance with the direction of the movement; and

changing, when the movement pattern is made only with movement of the touch on the second touch area, a view point of the 3-dimensional picture in accordance with the direction of the movement.

14. The method of claim 1, wherein the movement pattern comprises movement of the first touch in a first direction and movement of the second touch in a second direction.

15. The method of claim 14, further comprising:

executing at least one application and displaying an execution window of the at least one executed application before the detecting of the touch event, and

wherein the providing of the user interface in accordance with the movement pattern comprises altering the displayed execution window in accordance with the movement pattern.

16. A mobile terminal comprising:

a sensing unit including a first touch area and a second touch area that are formed on opposite surfaces of the mobile terminal;

a user interface unit for providing a user interface; and

a control unit for detecting a touch event that includes a first touch sensed on the first touch area and a second touch sensed on the second touch area, for identifying a movement pattern of the touch event, and for providing a user interface in accordance with the movement pattern.

17. The mobile terminal of claim 16, wherein the control unit distinguishes among an opposite direction movement pattern in which the first and second touches move in opposite directions, a same direction movement pattern in which the first and second touches move in the same direction, and a single touch movement pattern in which one of the first and second touches moves in a direction while the other stays at a position.

18. The mobile terminal of claim 16, wherein the control unit distinguishes among a vertical movement pattern in which at least one of the first and second touches moves up and down, a horizontal movement pattern in which at least one of the first and second touches moves left and right, and a circular movement pattern in which at least one of the first and second touches move circularly.

19. The mobile terminal of claim 16, wherein the movement pattern comprises movement of the first touch in a first direction and movement of the second touch in a second direction.
