A touch screen device and an operating method are provided in which only a specific position on a touch screen is activated to receive signals. The touch screen device includes a screen including a display configured to display menu images thereon and a detector configured to detect a screen touch, and a controller configured to control operations of the device according to the screen touch detected by the detector. The controller may cause the detector to be divided into an execution area configured to execute a menu when the menu placed on the execution area is touched, and a selection area configured to sequentially move the menu images to the execution area when the selection area is touched. Alternatively, the controller may cause the detector to be divided into a moving area configured to move a menu from a touch point along a drag line while the menu is dragged, and an execution area configured to execute the relevant menu when the touch on the execution area is released. With a touch screen device so configured, the menus are executed only in a limited execution area.

Touch screen device and operating method thereof

A touch screen device and an operating method thereof are provided. More specifically, a touch screen device is provided which allows a user to selectively restrict input through a touch screen. The touch screen device includes a screen that includes a display configured to display images thereon and a detector configured to detect a touch on the display and convert the touch into an electrical signal, and a controller configured to cause images to be displayed on the display and receive and process signals from the detector. Further, a user may determine whether the controller is operated according to the signal input into the detector. The determination may be made either by a switch separately installed on an earphone or by inputting a signal into the detector by a user.

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.
