P‐43: Effects of Changing Image Size on Depth Perception Using a Floating 3‐D Display

A floating-image display produces 3-D effects using a lens system that makes an image appear to float in the air. The authors examine the effects on depth perception and asthenopia of viewing a floating image that continuously changes in size. The results of the experiments suggest that viewers perceive the floating image to be moving back and forth as the image size changes despite the fact that the image's actual position does not change. Monocular depth cues, especially changes in size, enhanced the 3-D effects of images presented on the floating-image display.
