A
touchpad or
trackpad is a
pointing device featuring a
tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is outputted to the screen. Touchpads are a common feature of
laptop computers, and are also used as a substitute for a
mouse where desk space is scarce. Because they vary in size, they can also be found on
personal digital assistants (PDAs) and some
portable media players. Wireless touchpads are also available as detached accessories.
