Outline of Final Research Achievements

There have been reports on motion sickness and asthenopia induced by viewing stereoscopic films. Human equilibrium function deteriorates when viewing stereoscopic films, which may lead to motion sickness; however, the exact cause of such motion sickness remains unknown. In this paper, we investigate the effects of viewing 2-D/3-D films on human body, through stabilometry, electrogastrography (EGG), and subjective assessments. A comparison of time series data obtained at rest shows a significant change in the EGG 5 min after the onset of viewing the films. Further, sway values while viewing the 3-D film were considerably higher than those while viewing the 2-D film 60 min after the onset of viewing. These results show that the autonomic nervous system is affected first by long-term viewing of the stereoscopic film, and the equilibrium function deteriorates slowly over the course of the exposure.
