Electrophysiological characteristics of differences in emotional arousal between stereoscopic and non-stereoscopic virtual reality films

There are two modes for displaying panoramic movies in virtual reality (VR) environment, non-stereoscopic vision mode (2D) and stereoscopic vision mode (3D), whether there are differences in the activation effect of these two different continuous playback modes on emotional arousal and the correlation The properties of neural activity have not been adequately studied. This paper designs a cognitive psychology experiment, analyzes the scalp EEG signals collected synchronously, and compares the effects of VR-2D and VR-3D visual modes on emotional arousal, and uses support vector machines to verify VR-2D and VR-3D modes. Differences in neurophysiological characteristics. The results found that the brain electrical energy induced by VR-3D movies was significantly higher than that of VR-2D movies (mainly reflected in α and β activities), and the significantly increased β wave energy in VR-3D mode indicated that stereo vision brought more intense energy. At the same time, the stronger alpha activity in the occipita
