Peripheral viewing during exposure to a 2D/3D video clip: effects on the human body

Abstract

Objectives Symptoms of three-dimensional (3D) sickness, such as intoxication and eye fatigue, have been observed in subjects viewing 3D films and vary according to the image quality and visual environment. In addition, the influence of stereoscopic vision on the incidence of 3D sickness has not been explored sufficiently. Therefore, it is important to examine the safety of viewing virtual 3D content. Methods The present study examines the effects of peripheral vision on reported motion sickness during exposure to 2D/3D video clips for 1 min and for 1 min afterwards in human subjects. Stabilograms were recorded during exposure to video clips with or without visual pursuit of a 3D object and compared, and subjects were administered the simulator sickness questionnaire after stabilometry. Results There were no significant main effects of solidity of the visual stimulous (2D/3D) and the vision method (visual pursuit/peripheral viewing) in accordance with the two-way analysis of variance of the sway values, although the sway values during the 2D/3D video clips were higher than in control subjects. A consistent trend in the main effect of stability was observed. Further, the sway values changed remarkably after the 3D video clip was viewed peripherally and produced a persistent instability in equilibrium function. The questionnaire findings also significantly changed after the subjects viewed the video clips peripherally. Conclusions Subjective exacerbation and deterioration of equilibrium function were observed after peripheral viewing of 3D video clips. This persistent influence may result when subjects view a poorly depicted background element peripherally, which generates depth perception that contradicts daily experience.

On Mathematical Models of Two-Minute Stereoscopic Viewing on Human Balance Function

“…Previous studies have measured the body sway dur- ing/after the exposure to the video clips [11,17,18], and it has been shown that the equilibrium function is affected by the 3D viewing. Especially, the significant influence was obtained from the sway values with the eyes closed after viewing the 3D video clips [17,18].…”

Incidence and severity of Visually Induced motion Sickness during 3D laparoscopy In Operators who had No experience with it (VISION).

“…The primary outcome measure was the incidence and severity of VIMS. The score of VIMS was evaluated using the validated Simulator Sickness Questionnaire (SSQ), introduced by Kennedy et al [5] and used in many studies on 3D movies, 3D glasses, and 3D virtual reality games [6][7][8]. The questionnaire consists of 16 items on a four-point scale from 0 (none) to 3 (severe), with higher scores indicating worse motion sickness.…”

Expression of balance function during exposure to stereoscopic video clips

“…In previous studies, subjective exacerbation and deterioration of equilibrium function were observed after peripheral viewing of a 3D video clip [8,9]. A persistent influence has been observed while subjects view a poorly depicted background element peripherally, which generates depth perception that contradicts daily life.…”
