Objective evaluation of emotion (Kansei) was proposed to evaluate the state of mind of human beings, using analysis of brain wave (EEG). The EEGs were measured during and after the time that ten young women performed tasks that would elicit some emotions such as joy, excitement, irritation, and stress, among others. The subjects evaluated their own subjective feelings after each task. From the results of principal component analysis of the subjective evaluation values, the fundamental human emotions were explained along two axes, “Comfort (comfortable - uncomfortable)” and “Arousal (excited - calm)”, according to the opinions of many prominent psychologists. On the other hand, we calculated the cross correlation coefficients from power spectral analysis of α, β and &theta: waves measured through ten EEG electrodes. We tried to make a new database in order to calculate the emotions of human beings using “The Emotion Spectrum Analysis”, as proposed by T. Musha. The emotional values which were objectively calculated using the trial database agreed with the subjective evaluation values. In addition, we verified the above-mentioned trial database using emotions elicited from some odors.
