Touch screen device and method of selecting files thereon
First Claim
1. A method of selecting files using a touch screen device for a portable terminal, the portable terminal having a screen of a prescribed viewing area in x and y directions, the method comprising:
- detecting an initial touch point within a prescribed portion of the prescribed viewing area;
detecting a moving touch trajectory in a first direction on a surface of the screen, wherein the moving touch trajectory includes a substantially straight line, the substantially straight line initiating at the initial touch point and ending at a release touch point, and is determined based on x and y coordinates of the prescribed viewing area; and
executing at least one predetermined command based on the moving touch trajectory, the at least one predetermined command comprising at least one of detecting and marking a file list and skipping files in the file list, detecting and marking a file list and changing an execution order of files in the file list, or scrolling through a file list, wherein the executing step comprises maintaining the touch to continue scrolling until a desired file is located, and releasing the touch to mark the file list and skip the marked files in the file list, or to mark the file list and change the execution order of files in the file list, wherein when the file list is marked based on the moving touch trajectory, the file list includes files within a range that is defined by a rectangle with a diagonal equal to the substantially straight line of the moving touch trajectory, and wherein a different command is executed based on whether or not the initial touch point of the moving touch trajectory is the same as the release touch point of the moving touch trajectory.

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.

12. A touch screen device for a portable terminal, the portable terminal having a screen with a prescribed viewing area in x and y directions, the touch screen device comprising:
-
a screen, comprising; a display with a prescribed viewing area, wherein the display is configured to display information thereon; and a touch panel coupled to the display, wherein the touch panel is configured to detect an initial touch point within a prescribed portion of the prescribed viewing area, and a moving touch trajectory extending in a direction on a surface of the display, wherein the moving touch trajectory includes a substantially straight line, the substantially straight line initiating at the initial touch point and ending at a release touch point, and is based on x and y coordinates of the prescribed viewing area; and a controller coupled to the screen, wherein the controller is configured to execute at least one predetermined command based on the initial touch point and the moving touch trajectory, wherein the at least one predetermined command comprises detecting and marking a file list and skipping files in the file list, detecting and marking a file list and changing an execution order of files in the file list, or scrolling through a file list, wherein when the file list is marked based on the moving touch trajectory, the file list includes files within a range that is defined by a rectangle with a diagonal equal to the substantially straight line of the moving touch trajectory, and wherein a different command is executed based on whether or not the initial touch point of the moving touch trajectory is the same as the release touch point of the moving touch trajectory. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
