How virtual reality sickness affects the brain

Abstract

Cybersickness is a form of motion sickness that results from exposure to virtual reality (VR) environments. We aim to gain insight on the causes of cybersickness by using an electroencephalogram (EEG) machine. The EEG records electrical activity of the brain throughout a VR simulation, which sends event triggers to the EEG to signify changes in velocity. We created a new VR roller coaster simulation built in Unity, added effects that mitigate the symptoms of cybersickness and simulate various hardware limitations, and developed data analysis processes.
