ABSTRACT:
Information presented on a visual display is varied in content and size through the use of a single operator-manipulated input device. The foregoing is accomplished through the use of a novel command signal generator which includes a pivotally mounted rotatable shaft, high-resistance switches operatively associated with the shaft and logic circuitry responsive to command signals provided by the switches and by shaft rotation sensors for generating display control signals.
