A binocular stereo display is an effective device for virtual reality. However it might bring about embarassed situation when both real environment and virtual one are visible and contradictory with each other, since the relationship of occlusion between virtual and real environments is always determined by the architecture of the device used. In this paper we show the result of the psychophysical experiments under the contradictory condition of perceived distance caused by occlusion and binocular disparity, and it is found that this might result in unstable perception to cause binocular rivalry when depth of the vertical edge of the superposed area cannot be determined absolutely. Therefore it is suggested that this problem can be avoided by adding some specific clue for unique perception.
