Abstract

Current display systems use three-dimensional (3D) images projected on two-dimensional (2D) surfaces, sometimes call 2.5D. While these surfaces provide useful information, rotating the image often causes the operator to lose perspective. A 3D display, one providing a true three- dimensional view, eliminates this problem and provides a more intuitive image. This paper examines three applications where the 3D display provides definite operational benefits over the 2.5D display. First, the 3D display greatly benefits a homeland security application - baggage examination. Given a rotating x-ray sensor and a 3D display, the inspector examines baggage from all angles, identifying objects hidden underneath other items. Also a three dimensional view of the items significantly increases the probability of recognition when compared to a flat image. Second, a 3D display provides an intuitive, less cluttered image to Air Traffic Control (ATC) operators. Third, the 3D display is very useful in command and control suites, such as AWACS or JSTARS. Operators are able to see realistic representations of the battle space. Next, a description provides integration aspects of the 3D display. This includes the operator's ability to interact with systems not providing or needing 3D representation. Finally, a novel technology for implementing an autostereo display is discussed. The display provides look-around capability and is viewable by more than one person. An autostereo system does not require the use of special glasses, head trackers or other assistive aids.
