Abstract
Viewing stereoscopic films may have adverse effects, such as asthenopia and visually induced motion sickness (VIMS). The phenomenon of VIMS is not fully understood, so the aim of this study is to evaluate the effect of viewing a long stereoscopic film on the human body. We conducted stabilometric analysis on subjects in the Romberg posture, carried out flicker tests, and provided subjective questionnaires to detect fatigue and eye strain every 20 min. Symptoms of VIMS were detected during exposure to an hour-long stereoscopic film. The display size and the engagement were analyzed for their affect on the total locus length and the sway area, respectively. The severity of the motion sickness induced by viewing the 3D film was measured by stabilometry, and the analogous sway was not observed in participants after viewing the 2D film in this study. Based on these results, guidelines can be developed to ensure safety while viewing stereoscopic movies.
