Effect of Head-Mounted Display Virtual Reality with Visual Intervention on Motion Sickness Symptoms

Motion sickness (MS) is often experienced by individuals on moving vessels which the symptoms include fatigue, anxiety, dizziness, as well as vomiting. These conditions arise when the brain receives conflicting signal from eyes, vestibular receptors, and non-vestibular receptors. While medication is often used to treat MS, non-drug alternatives can also be considered for this purpose. Therefore, this research aimed to address this problem by producing non-drug therapy tool, namely Virtual Reality (VR). Specifically, head-mounted display (HMD) VR The display was used to present visual of sea horizon with islands. To evaluate the impact on reducing MS symptoms, the research compared clear visibility with reduced visibility as form of visual intervention. Approximately two types of videos were prepared using different color tones, namely cold and warm. The research also considered passengers’ position as a variable that correlated with MS. To assess the relationship between visual intervention and MS reduction, various parametric statistical tests were used, including Multiple Linear Regression and Paired t-test. In cases where the data did not meet the assumptions of parametric testing, nonparametric Wilcoxon test was applied. The result showed that the use of warm tone videos led to a significant reduction in MS symptoms, as evidenced by the outcome of t-test. Similarly, passengers’ position significantly affected MS, but visual intervention did not affect the condition.
