Study on the correlation between spatial information processing and EEG in VR environment

Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study is to quantitatively evaluate the effects of immersion factors in VR spaces on brain activity, focusing on differences in visual environments and locomotion methods. Previous experiments have confirmed that the stereoscopic effect in VR may promote theta activity in the frontal region. In this report, through experiments involving variations in bodily factors and locomotion methods, we found that the presence or absence of interactivity potentially causes differences in the response of high-frequency brainwave bands. Furthermore, in a comparison between real walking and joystick-based movement, no significant differences in frontal theta activity were observed due to the locomotion method. These results suggest that frontal theta activity remains independent of external factors and could serve as a stable indicator for evaluating the quality of the spatial environment itself.
