The use of virtual reality (VR) has made significant advancements, and now it’s widely used across a range of applications. However, consumers’ capacity to fully enjoy VR experiences continues to be limited by a chronic problem known as cybersickness. The proposed framework combines EEG neurofeedback with virtual reality, allowing users’ brain wave activity and cognitive states to be monitored and assessed throughout VR encounters. The empirical evidence amassed from the investigation delineates a significant correlation between the manifestation of cybersickness and enhanced neural activation within the parietal and temporal lobes. These findings were consistently manifested under two experimental conditions non simplification and geometrical simplification within the virtual reality (VR) environment. Notably, the observed decrement in activation intensity when employing geometrical simplification substantiates the effectiveness of our VR environment simplification strategy in the attenuation of cybersickness.
