Abstract
A low-cost semiconductor user input device for controlling the position of a pointer on a display includes a small array of composite sensors. Each composite sensor of the array is adapted to detect movement of a fingerprint feature. The user input device moves the pointer based upon the net movement detected by the composite sensors of the array.
