Graphic User Interface for Data Processing Device A handheld data processing device ( 82 ) has a touch-sensitive display screen ( 84 ) and interface means for generating a graphic user interface (GUI) on the screen, the GUI having one or more image elements ( 88, 92, 94, 96, 98, 100, 102 ), each representing an input. The screen ( 84 ) generates a control signal corresponding to an input in response to a portion of the screen on which an image element ( 88, 92, 94, 96, 98, 100, 102 ) representing said input is displayed being touched by a user of the device. The device has processing means for processing the control signal. The interface means is operable to locate the image elements ( 88, 92, 94, 96, 98, 100, 102 ) on an accessible portion of the screen ( 84 ) so that in use the image elements are within reach of a digit ( 90 ) of a hand in which the device is held. The image elements may, for example, be located in a fan in a corner of the screen, or in linear fashion along the edges of the screen. |
