An optical sensor (46) and two "click" buttons (50, 52) are mounted on a band (54) that is mountable onto the thumb of a computer user's hand. The "click" buttons (50, 52) are mounted side-by-side across the thumb. The optical sensor (46) is positioned endwise outwardly along the thumb (42) from the "click" buttons (50, 52). The band (54) is mounted on to a computer user's thumb (42) outwardly of the thumb joint. The optical sensor (46) and the "click" buttons (50, 52) confront the index and middle fingers (66, 68) on the user's hand. A relative movement of one of the user's fingers (66, 68) across the optical sensor generates a signal that controls movement of the cursor or pointer on a video display. Activation of the "click" buttons control specific software and pointing device functions. |
