Abstract
The cause of visual fatigue which stereoscopic images provides could be summarized into two issues, one is the issue of disagreement between vergence and accommodation and the other is the issue of interocular discrepancy. The latter issues might be considered to consists of vertical misalignment, rotational misalignment, difference of luminance, difference of color, temporal synchronization and so on. Recently we controlled these factors using the same stimuli and tried to measure quantitatively biomedical effects using with physiological (autonomic nervous system) and psychological (subjective scores concerning visual fatigue) indexes. In this paper, we report the experimental results using the factor of rotational difference.
