Outline of Final Research Achievements

Three dimensional visualization in movies, televisions and video games has been advancing rapidly. However, physiological and psychological effects of artificial stereoscopic vision on humans have not sufficiently been clarified. This study aimed at elucidation of the onset condition of so-called 3D sickness which is caused by artificial stereoscopic vision and the relationship between 3D sickness and visual fatigues. The experimental results have shown the followings: 1) Physiological indices for evaluation of 3D sickness may include psychological disturbance but it can be suppressed by adaptation. 2) It is possible that the cause of visual fatigue in stereoscopic vision can be explained using the contradiction between convergence and accommodation mechanisms. 3) Vertical disparity caused by the tilt of the head should be less than about 0.6 degree to avoid 3D sickness.
