시각 자극에 따른 EEG 신호 기반 감정 분석

초록

In this paper, we analyze the emotional changes based on EEG(Electroencephalogram) signal and the artifacts from the experimental environments according to the visual stimulation. We measured the activity of alpha, beta, and gamma waves of two subject in terms of ten target images. Experimental results show that alpha wave occurs in happiness, beta wave occurs in confusion, and gamma wave occurs in disgust and nervous emotion. In the case of sadness, three waves occurs together. In addition, we observed various artifacts such as EOG (Electrooculography), EMG(Electromyo graphy), latency of experimental progress, and noises in experimental environment.
