Abstract

In a method and apparatus of a touch screen portable terminal, a screen is classified into a first region displaying scrollable contents and a second region displaying non-scrollable contents. The contents of the first region are scrolled to previous or subsequent contents of a contents sequence responsive to a touch drag gesture detected on the second region. The second region may be a favorite shortcuts region of a home screen. Scrolling speed may be set according to moved distance of the touch drag gesture, or a speed of the touch drag gesture.

Claims

1. A screen change method of a touch screen portable terminal, the screen change method comprising:

classifying a screen into a first region displaying scrollable contents and a second region displaying non-scrollable contents; and

scrolling displayed contents of the first region to previous or subsequent contents of a contents sequence responsive to a touch drag gesture detected on the second region.

2. The screen change method of claim 1, wherein the contents displayed in the first region comprises at least one of application shortcuts and widgets.

3. The screen change method of claim 1, wherein the second region includes at least one of a region displaying favorite application shortcuts and a region displaying operating conditions of the portable terminal.

4. The screen change method of claim 1, further comprising:

detecting that the touch drag gesture has stopped at a point in the second region;

continuing to display the previous or subsequent contents if touch contact is detected to be released at the stopped point; and

continuing to scroll the displayed contents if the touch contact is detected to be maintained at the stopped point.

5. The screen change method of claim 1, wherein the scrolling of displayed contents comprises:

providing the subsequent contents when touch drag in one of a left and right direction is generated, and providing the previous contents when touch drag in the other of the left and right direction is generated, and/or providing the subsequent contents when touch drag in one of an upper and lower direction is generated and providing the previous contents when touch drag in the other of the upper and lower direction is generated.

6. The screen change method of claim 1, wherein the scrolling is performed at a speed proportional to a moved distance of the touch drag gesture.

7. The screen change method of claim 1, wherein the scrolling is performed at a speed proportional to a speed of the touch drag gesture.

8. The screen change method of claim 1, wherein the scrolling is performed at a speed proportional to a number of application shortcuts in the second region through which the touch drag gesture passes.

9. The screen change method of claim 1, wherein the scrollable contents displayed in the first region is data according to execution of an application, the data being scrolled according to the touch drag gesture.

10. The screen change method of claim 9, wherein the application is a word processing application and the data is data written by the application.

20. A non-transitory computer readable recording medium storing program instructions which, when executed within a portable terminal, cause the portable terminal to perform the method of claim 1.

11. A screen change apparatus for a portable terminal, the screen change apparatus comprising:

a touch screen unit that displays an image and outputs a signal according to touch input;

a storage unit storing operations data of the portable terminal; and

a controller configured to classify a screen provided through the touch screen unit into a first region displaying scrollable contents and a second region displaying non-scrollable contents and to control scrolling of the scrollable contents to previous or subsequent contents of a contents sequence responsive to a touch drag gesture detected on the second region.

12. The screen change apparatus of claim 11, wherein the scrollable contents displayed in the first region comprises at least one of application shortcuts and widgets.

13. The screen change apparatus of claim 11, wherein the controller designates at least one of a region displaying favorite application shortcuts and a region displaying operating conditions of the portable terminal are displayed as the region whose contents are fixed.

14. The screen change apparatus of claim 11, wherein the controller is further configured to:

detect that the touch drag has stopped at a point in the second region;

continue to cause the display of the previous or subsequent contents if touch contact is detected to be released at the stopped point; and

continue to scroll the displayed contents if the touch contact is detected to be maintained at the stopped point.

15. The screen change apparatus of claim 11, wherein the controller provides the subsequent contents when touch drag in one of a left and right direction is detected and provides the previous contents when touch drag in the other of the left and right direction is detected, and/or provides the subsequent contents when touch drag in one of an upper and lower direction is detected and provides the previous contents when touch drag in the other of the upper and lower direction is detected.

16. The screen change apparatus of claim 11, wherein the controller sets a speed at which the contents are scrolled to a speed proportional to a moved distance of the touch drag gesture.

17. The screen change apparatus of claim 11, wherein the controller sets a speed at which the contents are scrolled to a speed proportional to a speed of the touch drag gesture.

18. The screen change apparatus of claim 11, wherein the controller sets a speed at which the contents are scrolled to a speed proportional to a number of application shortcuts through which the touch drag gesture passes in the second region.

19. The screen change apparatus of claim 11, wherein the scrollable contents in the first region is data provided according to the execution of a word processing application, the data being scrolled according to the touch drag gesture.
