Abstract

We conducted an experiment that examined how visual discomfort arises while viewing autostereoscopic displays in a practical viewing situation. Visual discomfort was evaluated by measuring subjective symptoms and accommodative step response before and after viewing displayed material. Subjective discomfort measurements showed that viewing autostereoscopic displays resulted in relatively less discomfort than viewing 3D television with active shutter glasses. Moreover, we calculated the correlations between subjective visual discomfort and accommodation amplitude to near and far visual targets using an infrared optometer. With an autostereoscopic display and a 2D display, there was moderate correlation, whereas 3D television showed no correlation. This suggests that the discomfort arising from viewing autostereoscopic and 2D displays could be related to accommodative response. However, the discomfort arising from viewing 3D TV probably derives from other factors in a practical viewing.
