Psychophysical Influence of Mixed-Reality Visual Stimulation on Sense of Center-Of-Gravity
Last modified: 2011-09-02
Abstract
Mixed reality (MR) is the technology which merges real and virtual worlds in real-time. In MR space, a real object can be changed its visual appearance by superimposing a CG image (CGI) on it. Because it is said that the feeling of the weight is affected strongly by visual stimulation, we believe that it is affected similarly, in the case of presenting MR visual stimulation. If the behavior and extent of such an influence are well investigated, one real object can be perceived differently. In this study, we focus on the center-of-gravity (COG), and verify the influence of MR visual stimulation on sense of COG in MR environment. In this paper, we describe the systematic experiments of the influence. As the result, we obtained the interesting and promising result: (1) the sense of COG can be changed by MR visual stimulation, and (2) although the different feelings of COG between vision and sense of force, the feeling of COG can be represented by MR visual stimulation under certain conditions, (3) the influence from MR visual stimulation becomes smaller when COG positions of a real object and a CG image is distant.
