ABSTRACT=<sec><title>Background</title><p>Virtual 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.</p></sec><sec><title>Objective</title><p>In 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.</p></sec><sec><title>Methods</title><p>In 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.</p></sec><sec><title>Results</title><p>No 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 (<italic>p</italic> &lt; 0.005; <italic>p</italic> &lt; 0.01) after then the night video.</p></sec><sec><title>Conclusion</title><p>The present study examined the likely impact of brightness and contrast levels in VR environments on VIMS provocation.</p></sec>
