Abstract
Disclosed is a computerized data display system including a computer operating in accord with a window display management system for the display and control of a plurality of data windows on a display screen of a display device. The data windows are displayed on the display screen in a spatial relation corresponding to the field of view seen from a preselected viewing location selected by means of a control signal provided as an input to the computer. A head coupled image display device, coupled to the display screen of the display device, is adapted to display the data windows appearing on the display screen of the display device separately to each eye of a user to create a binocular, stereoscopic virtual screen image to the user that has a virtual screen size independent of the size of the display screen of the display device. A user controlled input position sensor, coupled to the computer, is adapted for generating the position control signal as an input to the computer to selectively change the selected viewing location.
