Abstract

A touch screen device and a method of operation are provided. The device and method allow for scrolling and selection of files from a file list, and for skipping or reversing an execution order of the selected files simply by performing a drag on a touch screen. The method of selecting files on the touch screen device includes detecting a diagonal drag on a screen, selecting file(s) included within a corresponding range, and skipping file(s) within the range. The method may also include changing an execution order of the selected file(s) when a drag with a return trajectory is detected. The method may also include scrolling through the file list in accordance with a direction and speed of the drag. The device and method allows a plurality of files to be selected and skipped at a time, and a desired file to be rapidly and easily located.

Claims

1. A method of selecting files on a touch screen, comprising:

detecting a touch drag on a screen;

detecting a file list included within a range corresponding to a touch drag trajectory of the detected touch drag; and

marking the detected file list for a subsequent execution action.

2. The method of claim 1, wherein detecting a drag on a touch screen comprises detecting an initial touch and a touch movement on the screen, and wherein the drag trajectory corresponds to a direction of the touch movement.

3. The method of claim 1, wherein marking the detected filed list for a subsequent execution action comprises skipping files included in the detected file list.

4. The method of claim 1, wherein marking the detected file list for a subsequent execution action comprises changing an execution order of files in the detected file list.

5. The method of claim 1, wherein the range corresponding to the touch drag trajectory is a range defined by a rectangle with a diagonal equal to a straight line which connects a start point and a release point of the touch drag.

6. The method of claim 1, further comprising:

determining whether the touch drag trajectory is a return trajectory; and

changing an execution order of files in the detected file list if it is determined that the touch drag trajectory is a return trajectory, wherein the detected file list is within a range corresponding to a rectangle with a diagonal equal to a maximum distance of the touch drag trajectory.

7. The method of claim 6, wherein changing an execution order of files in the detected file list comprises rearranging the execution order of the files in accordance with user preferences.

8. The method as claimed in claim 6, wherein changing an execution order of the files in the detected file list comprises reversing an execution order of the files included in the detected file list.

9. The method of claim 1, further comprising changing an appearance or a background color of the files included in the detected file list.

10. The method of claim 9, wherein changing an appearance of the files included in the detected file list includes changing at least one of a size, a letter color, or a background color of the files included in the detected file list.

11. The method of claim 9, wherein the files included in the detected file list are one of an audio file, a video file, or a graphic file.

12. A method of selecting files on a touch screen, comprising:

detecting a touch and a touch drag on a screen;

determining a direction and a speed of the touch drag; and

scrolling a file list displayed on the screen based on the determined direction and speed of the drag.

13. The method of claim 12, further comprising:

stopping the scrolling if a release of the touch is detected.

14. The method of claim 13, wherein the direction and speed of the drag are based on a touch point and a release point of the touch on the screen, and a time taken to move between the touch point and the release point.

15. A touch screen device, comprising:

a screen including a display configured to display a file list thereon and a detector configured to detect a touch on a screen; and

a controller configured to control operation of the device based on the touch on the screen detected by the detector, wherein, when a drag is detected on the screen, the controller is configured to skip files in the file list included within a range corresponding to an associated drag trajectory and to execute files adjacent the skipped files.

16. The device of claim 15, wherein the controller is configured to determine whether the drag trajectory is a return trajectory, and to change an execution order of files in the file list if the drag trajectory is a return trajectory.

17. The device of claim 16, wherein the controller is configured to determine that the drag trajectory is a return trajectory if a touch release point is substantially the same as an initial touch point.

18. The device of claim 16, wherein the controller is configured to change an execution order of files within a range in the file list corresponding to the drag trajectory if the drag trajectory is a return trajectory.

19. The device of claim 18, wherein the controller is configured to reverse an execution order of files in the file list if the drag trajectory is a return trajectory.

20. The device of claim 18, wherein the controller is configured to rearrange an execution order of the files in the file list in accordance with user preferences if the drag trajectory is a return trajectory.

23. Digital equipment comprising the touch screen device of claim 15.

24. The digital equipment of claim 23, wherein the digital equipment is an MP3 player, a PMP, a PDA, a notebook computer, a mobile communication terminal, or a portable navigation terminal.

21. A touch screen device, comprising:

a screen including a display configured to display a file list thereon and a detector configured to detect a touch and a drag on a screen; and

a controller configured to control operation of the device based on the touch and the drag on the screen detected by the detector, to determine a direction and a speed of the drag, and to scroll the file list based on the determined direction and speed of the drag.

22. The device of claim 21, wherein the controller is configured to detect a release of the touch and to stop the scroll if the touch is released.

25. Digital equipment comprising the touch screen device of claim 21.

26. The digital equipment of claim 25, wherein the digital equipment is an MP3 player, a PMP, a PDA, a notebook computer, a mobile communication terminal, or a portable navigation terminal.
