Touch device and method for providing tactile feedback

摘要

A touch device (150) includes a touch panel (10) and a vibration device (50) to provide tactile feedback to a user to locate a key (65) on a display (20) of the touch panel (10). A processor (100) generates a drive signal (130) to the vibration device (50) when the position on the display (20) touched by a finger or stylus (70) corresponds to a location of a key (65) on the display (20). The vibration device (50) causes the display (20) to vibrate (55) in response to the drive signal (130) to provide a tactile key location indication to the user while the key (65) is touched.
