VIMS can be measured by psychological and physiological methods, and the Simulator Sickness

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. The present study examines the effects of peripheral vision on reported motion sickness during exposure to 2D/3D video clips for 1 minute and for 1 minute afterwards in human subjects. The Simulator Sickness Questionnaire was administered after exposure to the video clips with or without visual pursuit of a 3D object and compared. The questionnaire findings significantly changed after the subjects viewed the video clips peripherally. This influence may result when subjects view a poorly depicted background element peripherally, which generates depth perception that contradicts daily experience.
