Is the brightness- contrast level of virtual reality videos significant for visually induced motion sickness? Experimental real-time biosensor and self-report analysis

BackgroundVirtual reality is no longer created solely with design graphics. Real life 360° videos created with special shooting techniques are now offered as open access to users’ experience. As a result, this widespread use of VR systems has increased the incidence of visually induced motion sickness.ObjectiveIn the present study, we aimed to investigate impact of brightness-contrast levels of real-life 360° videos on susceptibility to visually induced motion sickness during immersive virtual reality headset viewing.MethodsIn this study, 360° real-world day and night driving videos publicly available on YouTube VR were used as stimuli. Stimuli were presented in 2-min segments. Electrodermal activity was recorded throughout the stimulus presentation, and SSQ was administered immediately afterward.ResultsNo significant difference was found between the experiments in terms of dermal activity. There is a statistically significant difference in total SSQ scores and in symptoms of fatigue, eye strain, head fullness, blurred vision, and dizziness (p < 0.005; p < 0.01) after then the night video.ConclusionThe present study examined the likely impact of brightness and contrast levels in VR environments on VIMS provocation.
