Abstract

A method for controlling display of an object displayed on a touch screen in a mobile terminal is provided. The method includes displaying the object on the touch screen, generating an extension bar in response to a touch that is detected on the touch screen for a period of time, generating a zoom window in response to resizing of the extension bar, and zooming in and displaying content of the object in response to movement of the generated zoom window.

Claims

1. A method for controlling display of an object displayed on a touch screen in a mobile terminal, the method comprising:

displaying the object on the touch screen;

generating an extension bar in response to a touch that is detected on the touch screen for a period of time;

generating a zoom window in response to a resizing of the extension bar; and

zooming in and displaying content of the object in response to movement of the generated zoom window.

2. The method of claim 1, wherein the generated zoom window includes at least one move button comprising a move-up button, a move-down button, a move-left button and a move-right button, and the content of the object is zoomed in and displayed in response to a touch on the at least one move button.

3. The method of claim 1, wherein the generated extension bar is resized in at least one of up, down, left and right directions, and is changed to the generated zoom window if a zoom button constituting the generated extension bar is selected.

4. The method of claim 1, wherein the generated zoom window is used to zoom in and display the content of the object in a fixed position in response to movement by a touch of an object displayed on the touch screen.

5. The method of claim 1, wherein the generated zoom window is moved along with movement by a touch of an object displayed on the touch screen.

6. The method of claim 1, wherein, if a touch is detected on the displayed object in a portion other than the generated zoom window for a period of time, the generated zoom window moves to a point of the detected touch and displays zoomed-in the content of the object.

7. The method of claim 1, wherein, if a touch is made in a portion other than the generated extension bar and the generated zoom window, the generated extension bar and the generated zoom window are released.

8. The method of claim 1, wherein the zoom is variable.

9. A mobile terminal for controlling display of an object displayed on a touch screen, the mobile terminal comprising:

the touch screen configured to display the object; and

a controller configured to generate an extension bar in response to a touch that is detected on the touch screen for a period of time, generate a zoom window in response to resizing of the extension bar, and zoom in and display content of the object in response to movement of the generated zoom window.

10. The mobile terminal of claim 9, wherein the generated zoom window includes at least one move button of a move-up button, a move-down button, a move-left button and a move-right button, and the controller zooms in and displays the content of the object in response to a touch on the at least one move button.

11. The mobile terminal of claim 9, wherein the generated extension bar is resized in at least one of up, down, left and right directions, and the controller changes the extension bar to the generated zoom window if a zoom button constituting the generated extension bar is selected.

12. The mobile terminal of claim 9, wherein the controller zooms in on the content of the object in a fixed position and displays the zoomed-in the content of the object in the generated zoom window in response to movement by a touch of an object displayed on the touch screen.

13. The mobile terminal of claim 9, wherein the controller controls movement of the generated zoom window along with movement by a touch of an object displayed on the touch screen.

14. The mobile terminal of claim 9, wherein, if a touch is detected on the displayed object in a portion other than the generated zoom window for a period of time, the controller moves the generated zoom window to a point of the detected touch, and zooms in and displays the content of the object in response to the movement of the generated zoom window.

15. The mobile terminal of claim 9, wherein the controller releases the generated extension bar and the generated zoom window in response to a touch that is made in a portion other than the generated extension bar and the generated zoom window.

16. A method for controlling display of an object displayed on a touch screen in a mobile terminal, the method comprising:

displaying the object on the touch screen;

splitting the touch screen into at least two touch screens in response to at least one of a touch that is detected on the touch screen for a period of time, and selection of a zoom window function; and

displaying content corresponding to a zoom window on a first touch screen among the split touch screens, on a second touch screen.

17. The method of claim 16, wherein the second touch screen is used to zoom in and display the content corresponding to a zoom window in response to movement of the zoom window in at least one of up, down, left and right directions.

18. The method of claim 16, wherein the zoom window on the first touch screen is reduced in size in response to a pinch-to-zoom-in input on the second touch screen.

19. The method of claim 16, wherein the zoom window on the first touch screen is enlarged in size in response to a pinch-to-zoom-out input on the second touch screen.

20. The method of claim 16, wherein the second touch screen is used to zoom in and display content in the zoom window.

21. The method of claim 16, wherein content corresponding to a moving direction of a drag by a touch on the second touch screen is displayed in the zoom window.

22. The method of claim 16, further comprising converting the first touch screen into a keypad if a text window is selected on at least one of the first touch screen and the second touch screen.

23. A mobile terminal for controlling display of an object displayed on a touch screen, the mobile terminal comprising:

the touch screen configured to display the object; and

a controller configured to split the touch screen into at least two touch screens in response to at least one of a touch that is detected on the touch screen for a period of time, and select a zoom window function, and display the content corresponding to a zoom window on a first touch screen among the split touch screens, on a second touch screen.

24. The mobile terminal of claim 23, wherein the controller zooms in and displays content on the second touch screen in response to movement of the zoom window in at least one of up, down, left and right directions.

25. The mobile terminal of claim 23, wherein the controller reduces a size of the zoom window on the first touch screen upon detecting a pinch-to-zoom-in input on the second touch screen.

26. The mobile terminal of claim 23, wherein the controller enlarges a size of the zoom window on the first touch screen upon detecting a pinch-to-zoom-out input on the second touch screen.

27. The mobile terminal of claim 23, wherein the second touch screen is used to zoom in and display content in the zoom window.

28. The mobile terminal of claim 23, wherein the controller displays, in the zoom window, content corresponding to a moving direction of a drag by a touch on the second touch screen.

29. The mobile terminal of claim 23, wherein the controller converts at least one of the first touch screen and the second touch screen into a keypad, if a text window is selected on at least one of the first touch screen and the second touch screen.

30. The mobile terminal of claim 23, wherein the touch screen is split into the first touch screen and the second touch screen if the zoom window function is selected.

31. The mobile terminal of claim 23, wherein each of the first touch screen and the second touch screen is variably resized.

32. The mobile terminal of claim 29, wherein the first touch screen detects one of a pinch-to-zoom-in and a pinch-to-zoom-out and alters magnification of the content of the first touch screen in correspondence to a movement of the one of the pinch-to-zoom-in and the pinch-to-zoom-out, and

wherein a size of the second touch screen changes in inverse proportion to the magnification of the content of the first touch screen.
