Abstract: 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.
