Effects of Two-Minute Stereoscopic Viewing on Human Balance Function
Recently, with the rapid progress in image processing and three-dimensional (3D) technologies, stereoscopic images are not only available on television but also in theaters, on game machines, and elsewhere. In contrast to two-dimensional (2D) films that project flat images, stereoscopic films elicit the feeling of being at a live performance. However, asthenopia and visually-induced motion sickness (VIMS) can result from the exposure to these films. Even though various hypotheses exist, the pathogenesis of VIMS is still unclear. There is not enough knowledge on the effects of stereoscopic images on the living body, and the accumulation of basic research is thus important. The aim of this paper is to accumulate information relevant to VIMS and to examine whether the exposure to 3D video clips affects the human equilibrium functions. We evaluated body sway by conducting stabilometry studies. As a result, we verified that 3D viewing effects on our equilibrium function depends on exposure time.
