Abstract

A method for changing a screen size using a multi-touch preferably comprises: executing a contents; inputting a multi-touch signal that requests a display size change of a contents screen that executed the contents. At least one of the horizontal display size and the vertical display size of the contents screen are changed in size according to the inputted multi-touch signal, and outputting the changed contents screen.

Claims

1. A method for changing a screen display size using a multi-touch, the method comprising:

executing a contents by a controller and outputting the contents to a display;

receiving by a touch screen a multi-touch input signal that requests a display size change of a contents screen that executed the contents; and

changing by the controller the display size of at least one of a horizontal display size and a vertical display size of the contents screen being displayed according to the inputted multi-touch signal, and outputting signal to the display to change the size of contents screen being displayed.

2. The method according to claim 1, wherein the controller only changes the horizontal display size of the content screen being displayed in response to the received multi-touch input signal.

3. The method according to claim 1, where the controller only changes the vertical display size of the content screen being displayed in response to the received multi-touch input signal.

4. The method of claim 1, wherein the received multi-touch input signal comprises a predetermined plurality of touch points.

5. The method of claim 1, wherein the received multi-touch input signal comprises touches three points substantially simultaneously.

6. The method of claim 1, where in the received multi-touch input signal is a captured gesture that is matched by the controller with a gesture in a template database.

7. The method of claim 4, wherein changing at least one of the horizontal display size and the vertical display size of the contents screen comprises:

increasing the horizontal display size and the vertical size of the contents screen at the same time in response to detecting by the display three touch points in a circle and a distance between the three touch points being increased by stretching a distance between three fingers;

increasing the horizontal display size of the contents screen when detecting a user touching three horizontal touch points in a row, and detects movement of two end touch points of the three horizontal touch points in a horizontal direction away from a middle touch point of the horizontal row; and

increasing the vertical display size of the contents screen when detecting a user touching three vertical touch points in a column, and detecting movement of two end points of the three vertical touch points moving in a vertical direction further from the touch point in the middle of the column.

8. The method of claim 4, wherein changing at least one of the horizontal display size and the vertical display size of the contents screen comprises:

decreasing the horizontal display size and the vertical display size of the contents screen at the same time when detecting touches of three points in a circle, and pinching the three touch points toward each other;

decreasing the horizontal display size of the contents screen when detecting touches of three points horizontally in a row, and detecting movement of the touches of two end points in a horizontal direction toward the touch point in the middle of the horizontal row; and

decreasing the vertical display size of the contents screen when detecting touches of three points vertically in a column, and detecting movement of the touches of two end points in a vertical direction toward the touch point in the column.

9. The method of claim 4, wherein changing at least one of the horizontal display size and the vertical display size of the contents screen comprises:

increasing the screen size by detecting movement of only one corresponding side from among a plurality of sides of the contents screen when detecting one of the touch points of two end points is moved in a direction away from the touch in the middle while touching three points in a row; and

decreasing the screen display size by detecting movement of only one corresponding side from among a plurality of sides of the contents screen when detecting one of the touches of two end points is moved in a direction closer to the touch in the middle while touching three points in a row.

10. The method of claim 1, further comprising:

restoring by the control the changed contents screen into the original size when detecting input of a preset restoration key signal.

11. The method of claim 1, wherein changing at least one of the horizontal display size and the vertical display size of the contents screen comprises:

converting image data for the contents screen output to correspond to a display size of the changed contents screen according to a multi-touch input.

12. An apparatus for changing a screen size using a multi-touch, the apparatus comprising:

a display panel that receives and outputs a contents screen that displays a contents;

a touch panel that generates a multi-touch input signal based on detected touch to request a display size change of the contents screen; and

a controller that controls change of at least one of the horizontal display size and the vertical display size of the contents screen according to the inputted multi-touch and outputs the changed contents screen.

13. The apparatus of claim 12, wherein the multi-touch detected by the touch panel touches comprises detecting touch of a plurality of points at substantially a same time.

14. The apparatus of claim 13, wherein the multi-touch detected by the touch panel comprises detecting touch of three points at substantially the same time.

15. The apparatus of claim 13, wherein the controller increases the horizontal display size and the vertical display size of the contents screen at the same time when the controller detects touching of three points in a circle, and detects stretching of the touches of the three points in a direction away from each other;

and increases the horizontal display size of the contents screen when the controller detects touching of three points horizontally in a row, and detects movement of the touches of two end points in a horizontal direction further away from the middle of the row while fixing the touch in the middle; and

increases the vertical display size of the contents screen when the controller detects touching of three points vertically in a column, and detects movement of the touches of two end points in a vertical direction is away from the touch in the middle while fixing the touch in the middle.

16. The apparatus of claim 13, wherein the controller decreases the horizontal display size and the vertical display size of the contents screen at the same time when the controller detects touching of three points in a circle, and detects pinching of the touches of the three points;

the controller decreases the horizontal display size of the contents screen when the controller detects touching of three points horizontally in a row, and detects movement of the touches of two end points in a horizontal direction closer to the touch point in the middle while fixing the touch in the middle; and

the controller decreases the vertical display size of the contents screen when the controller detects touching of three points vertically in a column, and detects movement of the touches of two end points in a vertical direction closer to the touch in the middle while fixing the touch in the middle.

17. The apparatus of claim 13, wherein the controller changes the screen display size by moving display of only a side corresponding to a touch movement from among all sides of the contents screen when detecting movement of one of the touches of two end points while touching three points in a row.

18. The apparatus of claim 12, further comprising:

an input unit comprising a restoration key that restores the changed contents screen to the original size for display.

19. The apparatus of claim 12, further comprising:

a display-panel-driving driver that converts image data for the contents screen to correspond to a size of the changed contents screen according to a multi-touch input.
