Abstract

This paper introduces a method to merge real and virtual worlds in a mirror, and experiments to evaluate depth perception by motion parallax in the mirror world. Recently, the functions of a real mirror are enhanced by Mixed-Reality technique. In order to merge real and virtual worlds, conventional systems use a video monitor and a video camera as a metaphor of mirror. Therefore, it is difficult for them to reproduce motion parallax of a real mirror in Mixed-Reality world. Our method can reproduce motion parallax of a real mirror in Mixed-Reality world. A user can understand 3D position of mirror images with our method. Motion parallax is well known as one of the important stimuli to understand the depth information of the observing 3D object. However, the depth perception of motion parallax in the front-back reversal space as a real mirror world has not been clarified. The results of our subjective evaluations reveal that the motion parallax improves our depth perception, even in Mixed-Reality mirror world.
