Research on Depth Perception when Walking in Virtual Space

Abstract

People perceive depth on a daily basis because of the presence of both eyes. The factors that contribute to depth perception include binocular disparity, motion disparity, and convergence. In our previous studies, we quantified the visual effects of size and the amount of information in the visual field, and conducted experiments to evaluate CG images displayed on a display. In these experiments, the relationship between the depth of the content and the sense of discomfort was demonstrated by using inverse-viewing (switching the left and right images) as a means of evaluation. In this study, as a new attempt of research on depth, we consider depth perception using inverse-viewing when walking in a virtual space. As an experiment, we created two types of rooms in a virtual space and subjectively evaluated the difference in depth brought about by the addition of information and movements in the virtual space in the forward-viewing state and the reverse-viewing state.
