Abstract

A touch screen device and an operating method thereof are provided. The touch screen device is operated by touching a touch screen and moving a touch while the touch is maintained on the screen. A detector detects a touch point and a moving trajectory, and a controller selects a user command based on the detected touch point and moving trajectory. Then, when the user releases the touch, the controller executes the user command. User commands are classified and stored in a storage device and then executed by the controller based on operation modes associated with the device. A variety of user commands may be executed even though not all the menus are not displayed on the screen at once. Further, a user may cancel an erroneously entered user command quickly and easily.

Claims

1. A method of operating a touch screen device, comprising

detecting a touch, an initial touch point and a moving touch trajectory on a surface of a screen;

determining a command corresponding to the initial touch point and moving touch trajectory; and

executing the determined command when the touch is released.

2. A touch screen device, comprising:

a screen including a display that displays information thereon and a detector an initial touch point, a moving touch trajectory and a touch release point on the display; and

a controller that executes a command based on the detected initial touch point and moving touch trajectory.

3. A touch screen device, comprising:

a screen comprising a display that displays menu images thereon and a detector that detects a touch on the screen, wherein the detector is divided into an execution area and a selection area; and

a controller that controls the touch screen device based on the detected touch on the screen.

4. A method of operating a touch screen device, the method comprising:

detecting a touch on a screen;

executing a relevant menu placed on a touch point when the touch point is within an execution area of the screen; and

sequentially moving menu images placed on a selection area of the screen to the execution area when the touch point is within the selection area.

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

detecting a touch drag on a screen;

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

marking the detected list for a subsequent execution action.

6. A touch screen device, comprising:

a screen including a display configured to display a list of items 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 items in the list included within a range corresponding to an associated drag trajectory and to execute items adjacent the skipped items.

7. A method of operating a touch screen device, the method comprising:

displaying a plurality of menus on a screen, each of the plurality of menus including a menu bar having an expanded portion at one end thereof, wherein each of the expanded portions are arranged in an alternating pattern on the screen.

8. A touch screen device, comprising:

a screen including a display that displays menu images thereon and a detector that detects a touch on the screen; and

a controller that displays two or more menu bars on the screen, the menu bars each having an expanded portion at one end portion thereof, wherein the two or more menu bars are displayed on the screen such that the expanded portions are arranged in an alternating pattern.

9. A method of displaying images on a touch screen device, the method comprising:

displaying two or more display windows on a screen in a partially overlapped manner; and

moving an underlying display window to an overlying position when a touch is detected on the underlying display window that is covered by an overlying display window.

10. A touch screen device, comprising:

a screen comprising a display that displays images thereon and a detector that detects a touch on the screen; and

a controller that displays two or more display windows on the screen in a partially overlapped manner, and moves an underlying display window to an overlying position when a touch is detected on the underlying display window covered by an overlying display window.

11. A touch screen device, comprising:

a screen comprising a display that displays images thereon and a detector that detects a touch and movement of the touch on the display; and

a controller configured that retrieves image information corresponding to the detected movement and displays an image on the screen.

12. A method of operating a touch screen device, the method comprising:

detecting a touch and a movement of the touch on a screen;

retrieving an image corresponding to the movement; and

displaying the retrieved image on the screen.

13. A touch screen device, comprising:

a screen comprising a display that displays images thereon and a detector that detects a touch on the screen;

a controller that controls operation of the touch screen device in accordance with the screen touch detected by the detector; and

a switch that selectively transmits a signal from the detector to the controller.

14. A touch screen device, comprising:

a screen comprising a display that displays images thereon and a detector that detects a touch on the screen; and

a controller that receives signals input from the detector when an activation signal is input to the controller, and that ignores input signals when a holding signal is input to the controller.
