ABSTRACT:
A touch pad such as a keypad or a touch screen is mounted with at least one vibrator to produce a tactile feedback sensed by the user as the pad is touched with a finger or a pointer. The vibrator is controlled by a processor such that it will vibrate for a predetermined length of time in the range of 50 to 1000 ms and at a predetermined amplitude. The vibrator is also selected to vibrate at a frequency between 100 and 5000 hz. The touch screen may be any of the analog resitive, infrared, accoustic, capacitive or electromagnetic inductive type operated devices.
