| Abstract(in English) | The state of mind of human being is closely related to the brain functional activities. Hence the features of the state of mind are considered to appear in the complexity of EEG potential dynamics. In practice, on the basis of the spatio-temporal dynamics of EEG, Musha proposed the emotion spectrum analysis method, ESAM , for abbreviation. In his approach, EEG features were extracted from the cross-correlation coefficients of EEGs measured through ten EEG electrodes in the θ, α, and β frequency bands so as to extract the fundamental emotions such as anger, joy, sadness, and relaxation. In this paper, prior to EEG analyses by means of the Emotion Spectrum Analysis Method, we perform Independent Component Analysis for EEG signals. In addition we shall evaluate the relationship between the input vector characteristics and emotion output in terms of an emotion matrix. We shall examine the relations between the measured location and the resultant emotions. As results, the improvement in the recognition accuracy up to 23[%] -51[%] is found be carried out by means of the Independent Component Analysis. When subjects imagine four fundamental emotions, one may find the relation between the measured location on the basis of F_4, T_3, and O_1 and the emotions through the constructed emotion matrix. |
