USER INTERFACE WITH ENLARGED ICON DISPLAY OF KEY FUNCTION

摘要

A user interface combines the use of capacitive sensors (20) with tactile sensors (22) in an input device (18). When a user places a finger near a key (16a-d, 17), a capacitive sensor causes the display (14) to display temporarily an indication of the key function in an enlarged format. The user may then press the associated key to activate the desired function. In one exemplary embodiment, the capacitive sensor fixes the functionality to the function indicated in the display. A tactile input applied to any key, whether the correct key, multiple keys, or single incorrect key, results in activating the function indicated in the display as a result of the capacitive input.
