| Research Abstract |
The first purpose of this study is to propose the estimating method of the intensity of human emotion for fun and pleasure using facial expression and physiological data. The index of facial expression is the transverse width of mouth and the indices of physiological data are heart rate and skin conductance level. The three indices were measured while subjects wore seeing comedy movies. The subjects roported their evaluation for fun and pleasure with four intensity levels(0, 1, 2 and 3) after movie. Using the throe indices, the estimation formula based on multiple regression model was derived. The estimated intensity was compared with reported one. The mean error of estimation was about 0.3, It was concluded that the proposed methocl would be able to estimate the intensity of human emotion for fun and pleasure. The second purpose of this study Is to evaluate the differonce of α wave(8Hz 〜 13Hz) of electroenceph ilogram(EEG) on comfortable and uncomfortable emotron usmg three mdices - 1/f^m fluctuations, power of awave and power flow. The subjects were sixteen adults(20〜23 years old). The electrodes were attachedto Fpl Fp O_l 0_2 in the international l0/20 EEG system On 1/f^m fluctuations analysis ofFpl electrode F_<p1>, F_<p2>, O_1, O_2 mean value of m in the comfortable emotion was larger than uncomfortable one. This result was the same one as the precedrng research. On (xwave power 'analysis, there were no significant difference between comfortable and uncomfortable emotion in each four electrodes. Power f'low from one eleotrode to other three electrodos was calculated by autoregressive model. Experimental results showed that mean value of power flow in the uncomfortable emotion was larger th, an comfortable one on F_<p1>, F_<p2>, O_1, O_2.
