Abstract
Improving depth perception accuracy in virtual environments is an important research topic to use 3D vision technology for quantitative practice. This study examines the impacts of various depth cues on human depth perception in a specialized virtual environment where images are magnified for viewing. It expands on the results of preliminary research that suggested promising techniques to improve depth perception accuracy. The study evaluates a focused area of the medical industry; it analyzes the application of enhanced graphics techniques selectively onto 3D medical images. Expanded experimental tests were conducted on a one-wall 3D projection system to display a scene with redesigned depth cues. The previous study showed viewers tend to underestimate depth in virtual environments. This follow-up experiment revealed the enhanced graphic techniques improved accuracy in depth estimation; it suggested future research directions for utilizing 3D vision technology in medical tasks where quantitative analysis can provide significant benefits and advantages for examining medical images.
