The use of Virtual Reality (VR) is essential to entertainment, architecture, and other industry as well as science. So, it is important to develop the cost-effective VR with the superior feeling of “Reality”. To accomplish the requirement, we have to provide human appropriate sensory stimuli to enhance the sense of reality and immersion. In human, the most part of sensory information are owing to vision, and it is sure to play an important role in VR environment. One of the important psycho-physiological effects in VR is visually induced perception of self-motion, called vection. In this study, we investigated circular vection to specify the optimal parameter for the visual stimulus, such as spatial frequency, temporal frequency, and stimulus speed. And we revealed that the induction of circular vection depended on the multiple parameter of visual stimulus. Our results are suggested that selecting fundamental parameter of visual stimuli is important to improve the human experience of reality and reduce the side effects, such as motion sickness.
