Abstract: An integrated attitude director indicator and horizontal situation indicator is disclosed that utilizes stereopsis to combine information that normally requires two display surfaces onto a single electronic display. One embodiment of the display comprises left and right eye versions alternately presented on the display in synchronism with alternate eye shuttered lenses worn by the viewer. The viewer has an instantaneous sense of the real world direction from his aircraft as apparently suspended within a spherical grid. The integrated display provides a presentation somewhat similar to existing flat screen separate instruments with an aircraft symbol lying at the center of the sphere with roll, pitch and heading scales displayed on this sphere. The sphere itself has one color such as blue above the horizon line and a different color such as brown below the horizon line.

Abstract: A design and evaluation system is disclosed which enables the computer generation of graphic displays and symbology used in the design of electronic instrument displays. The graphics and symbology may be positioned, rearranged, altered, and replaced with other graphics or symbology representative of that used in the intended instrument. The display may then be dynamically tested in accordance with programmed or selected manual inputs to determine the aesthetic and functional interactions between symbols or groups of symbols and to evaluate their acceptability in their intended environment. The proposed display may be repeatedly updated, altered and modified during testing until a final version has been selected for the instrument display.
