Recently, various studies of human factors have been conducted to reveal stereoscopic characteristics of the human visual system and visual fatigue. In this paper, we investigate the effect of vergence-accommodation conflict and parallax difference on binocular fusion for random dot stereograms. The aim of this paper is to provide a study on visual fatigue induced by the conflict. We measured the time required for fusion under various conditions that include foreground parallax, background parallax, focal distance, aperture size, and corrugation frequency. The results show that foreground parallax and parallax difference between foreground parallax and background parallax have significant influences on fusion time. In addition, we verify the relationship between fusion time and visual fatigue by conducting a subjective evaluation of stereoscopic images.
