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 operating method thereof are provided. The touch screen device includes a screen including a display configured to display images thereon and a detector configured to detect a user touch and movement thereof, a storage device configured to store image information corresponding to the movement, and a controller configured to retrieve and display an image corresponding to the detected drag. The image may include at least one of a trace image representing a moving trajectory, an icon image, or a text image.

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.

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.

Touch screen device and method of selecting files thereon

A touch screen device and method of displaying images using display windows and selecting execution menus displayed on the display windows in a touch screen device are provided. The touch screen device includes a screen, a display configured to display images thereon and a detector configured to detect a touch on the screen, and a controller configured to control operation of the touch screen device in accordance with the screen touch detected by the detector. The controller causes two or more display windows to be displayed in an overlapped manner. Further, if the touch is detected on an underlying display window covered by an overlying display window, the controller causes a display form to be changed in response to the touch. That is, if a touch is detected on the display window covered by the overlying display window, the touched display window is displayed as an overlying display window.

Touch screen device and method of displaying images thereon

Touch screen device and method of method of displaying images thereon

A touch screen device and method for displaying and selecting menus thereof are provided. The touch screen device includes a screen with a display for displaying menu images thereon and a detector for detecting a touch on a screen, and a controller which displays one or more menu bars on the screen. Each of the menu bars may have an expanded portion at one end thereof, and the menu bars may be displayed such that the expanded portions are arranged in a zigzag pattern to facilitate menu selection and reduce input errors. When two or more menu bars are erroneously touched, the controller may enlarge and display the touched menus so that a new touch input for the correct menu can be easily made. Thus, menus displayed on the touch screen may be arranged for easy selection, and input errors may be easily corrected.
