Electrophysiological Changes in the Virtual Reality Sickness EEG in the VR sickness

This paper proposes a specific brain wave in which changes in virtual reality (VR) sickness are noticeably observed by comparing stages before and during the watching VR video. Although VR sickness generally induces physical symptoms such as headache, dizzy, and nausea and causes difficulties in using VR devices, there were still insufficient methods to quantify the degree of VR sickness. We divided the experiment into three conditions: baseline, VR video, and recovery. Each condition was measured by electroencephalography (EEG) to examine which frequency band responded prominently. The absolute power of alpha wave decreased during VR video condition compared to the baseline, and after the VR sickness was relieved, the absolute power of alpha wave increase during recovery condition compared to the VR video condition.
