Abstract
A workstation with multiple, functionally related displays clustered under and controlled by a common transparent overlay control device. The position of a hand-held stylus is sensed by the overlay control device and is used as a system input to control system operations, system communications and input, manipulation and editing of images displayed on the displays. Control of certain workstation operations is achieved by directing the stylus towards function symbols which are affixed to the overlay surface. Actuators or other adjustment mechanisms are provided for adjustment of the height and pitch of the workstation for the comfort of the operator. Further, the workstation provides integrated data audio communication over ordinary narrow-band telephone lines or high speed data lines with other linked workstations.
