Abstract: A method of inputting a user command includes displaying a navigation window including letter key symbols corresponding to keys on a manipulator. If a first user command as to a specific key on the manipulator is input, a specific letter key symbol on the navigation window corresponding to the specific key is activated, and if a second user command as to the specific key is input, the letter corresponding to the activated specific letter key symbol is input. Accordingly, even if the manipulator is separated from the display on which a result of the manipulator is displayed, the user can input a user command by looking at the display only.

Abstract: An input method and apparatus for a device having a graphical user interface (GUI)-based display unit includes allocating at least one region for a plurality of input units disposed on the device, defining input types different from each other for the allocated region, and controlling menu displayed on the display unit according to a signal input in the allocated region based on the defined input types. According to the method and apparatus, the use method and layout of a physically fixed input apparatus can be flexibly changed, thereby increasing the use scope of input types. Also, by integrating navigation inputs, character inputs, and button inputs, efficiency of using the area of a mobile device increases.

Abstract: Provided is a control method for a digital image processing apparatus having a movement mode in which a user moves a target object to a target position, the method including: displaying icons including an image icon of a target object and an icon indicating a target position; displaying an icon indicating a new target position in response to the detection of a target position change signal; displaying an image icon of a new target object in response to the detection of a target object change signal; and moving the target object of the image icon currently displayed to the target position indicated by the icon currently displayed in response to the detection of a movement signal.

Abstract: Provided is a digital image processing apparatus including: an array of a plurality of input buttons; and a display panel which displays icons respectively corresponding to the input buttons at positions respectively corresponding to positions of the input buttons, and a method of controlling the apparatus.

Abstract: An electronic device for 3-dimensionally inputting a user command and a method employing the same are provided. The electronic device includes a touch pad sensing a 3-dimensional interface and a controller controlling a GUI (graphical user interface) in response to the 3-dimensional interface sensed by the touch pad. Thus, a user command can be 3-dimensionally input so as to harmonize a 3-dimensional varying method of a 3-dimensional GUI with a 3-dimensional input manipulation of a user.
