Abstract
A touch pad machine control system uses a touch pad having an overlay to define control strip surface areas which perform different functions. The contact of an operator's finger along one of the defined control strips selects a desired function and produces the desired machine motion from the rate, distance or duration of finger contact according to the desired function. The result is equivalent control motion without the need for moving parts.
