Abstract
A hand held unit can operate as a mouse to move a cursor on a display, as a hand held optical scanner for entering into a computer characters or graphic information delineated on a work sheet across which the unit is moved, or as a digitizing puck for tracing and digitizing lines or curves on a work sheet laid over a digitizing pad. The unit is connected via an electrical cable to an interface board plugged into an expansion slot inside a personal computer.
