Touch pads require the light touch of a finger gliding across the
surface to move the mouse pointer. A tap of the finger acts as a
"click". They call for accurate, yet minimal arm and wrist
motion. Driver software provides for customizing the buttons for
easier control. Laptop computers often use this technology.
