APPARATUS AND METHOD FOR INTUITIVE KEYPAD NAVIGATION WITH AUDIO FEEDBACK FOR A WIRELESS COMMUNICATION DEVICE |
摘要 |
A wireless communication device (101) having intuitive audio keypad navigation features is provided. Each of the keys (140-151) of a keypad (132) of the wireless communication device (101) is assigned a different audible signal (FIGS. 3-4). When a user of the wireless communication device (101) presses one of the keys (140-151), a processor (112) responds by triggering an output driver (124). The output driver (124) generates a unique output signal corresponding to the pressed key (140-151). A speaker (122) or alert circuit (126) is responsive to the triggering of the output driver (124) to generate a unique audible signal (FIGS. 3-4) associated with the unique output signal of the pressed key (140-151). In this manner, an audio feedback is provided to the user that uniquely identifies each of the keys (140-151) as they are pressed.
