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.
Claims8
A touch pad comprising:
- touch pad means having a surface to be touched by a user to provide an output as a function of the location touched on the surface;
- and
- at least one vibrator fixed to the touch pad means surface to be touched to provide a tactile vibrating sensation to the user for a predetermined fixed time at a predetermined fixed frequency between 100 and 5000 Hz. when any location of the surface is being touched.
A touch pad comprising:
- touch pad means having a surface to be touched by a user to provide an output as a function of the location touched on the surface;
- and
- at least one vibrator fixed to the touch pad means surface to be touched to provide a tactile vibrating sensation to the user for a predetermined fixed time between 50 ms. and 1000 ms. at a predetermined fixed frequency when any location of the surface is being touched.
