Design and Perception Testing of a Novel 3-D Autostereoscopic Holographic Display System; Conference paper

摘要

U.S. Army Tank-Automotive Command (TACOM) researchers are in the early stages of developing an autostereoscopic, 3-D holographic visual display system. The present system uses holographic optics, low and high-resolution projectors, and computer workstation graphics to achieve real-time, 3-D user- interactivity. This system is being used to conduct 3-D visual perception studies for the purpose of understanding the effects of 3-D in military target visual detection and as an alternative technique to CAD model visualization. The authors describe the present system configuration, operation, some of the technical limitations encountered during the system development, and the results of a human perception test that compared subject response times, hit rates and miss rates of visual detection when subjects used conventional 2-D methods versus the 3-D holographic image produced by the holographic display system. The results of this study revealed that 3D HOE system increased the perception of accuracy of moving vehicles. This research has provided some insights into which technology will be the best for presenting 3-D simulated objects to subjects or designers in the laboratory.
