Form in Potential Functions While Maintaining an Upright Posture during Exposure to Stereoscopic Video Clips
Visually induced motion sickness (VIMS) is a well-known phenomenon in viewing video, playing video games and others. The VIMS is caused by sensory conflict, the disagreement between convergence and visual accommodation while observing stereoscopic images. The VIMS can be measured by psychological and physiological methods. We propose a mathematical methodology to measure the effect of 3-dimensional (3D) images on the equilibrium function. In this study, body sway in the resting state is compared with that during exposure to 3D video clips on a liquid crystal display and on a head mounted display. In addition, the Simulator Sickness Questioner (SSQ) was completed immediately afterward. Based on the statistical analysis of the SSQ sub-scores and each index for stabilograms, we succeeded in determining the quantity of the VIMS duing exposure to the stereoscopic images. Moreover, we discuss the metamorphism in the potential functions to control the standing posture during the exposure to stereoscopic video clips.
