ABSTRACT:
A cursor control device for personal computers and workstations includes various embodiments, some of which include a patterned ball and some of which rely on other patterned surfaces, which recognizes changes in the position of the pattern relative to a sensor having an array of photosensitive elements. Circuitry associated with the sensor determines movement of the pattern across the array, and translates that movement into conventional cursor control signals supplied to a host system.
