Abstract:
A touch device includes a touch panel and a vibration device to provide tactile feedback to a user to locate a key on a display of the touch panel. A processor generates a drive signal to the vibration device when the position on the display touched by a finger or stylus corresponds to a location of a key on the display. The vibration device causes the display to vibrate in response to the drive signal to provide a tactile key location indication to the user while the key is touched.
