Background and Objectives : Virtual reality (VR) users have prevalently experienced motionsickness called cybersickness. Recently, it has been suggested that stimulating the mastoidby vibration relieves cybersickness. This study aimed to verify this proposition.
Subjects and Method : Fifty-four young male adults (aged 18 to 27 years) without any experienceof severe motion sickness or cybersickness participated in this study. Participants weredivided in half into two groups, the experimental group and control group. The experimentalgroup used VR with mastoid vibration, and the control group experienced VR without mastoidvibration. Participants responded to the simulator sickness questionnaire (SSQ) to quantifycybersickness.
Results : The total severity scores of cybersickness in the experimental group ranged from 0to 183.3 with the mean value of 46.7±49.0. The total severity scores of cybersickness in thecontrol group ranged from 0 to 194.9 with the mean value of 44.9±45.1. There were no significantdifferences between the two groups.
Conclusion ; There was no improvement of cybersickness in the VR participants when themastoid was stimulated by vibration. However, cybersickness might be relieved with changesin the VR condition or vibration settings.
