ABSTRACT:
A compact, low-cost pad pointing device with improved performance, reliability and durability, having an integrated selection switch, that can be used as a cursor pointing device and selection mechanism for computers, remote controls, web TV, TV guide browsers, video games, consumer electronics, industrial controllers, medical, automotive and other applications. A contact surface can be deflected to positions on an electrical medium that results in the generation of speed and direction signals while a selection switch may be simultaneously activated through the same control element.
