EEG(Electroencephalogram) based emotion analysis according to visual stimulus

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 know that laboratory temperature, laboratory noise, posture, and eye movement should be minimized to remove artifacts, and the desired EEG waveform can be obtained using various filters 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.
