项目摘要

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.

本研究的第一个目的是提出利用面部表情和生理数据来估计人类对乐趣和愉悦的情感强度的方法。面部表情指标为口腔横向宽度，生理数据指标为心率和皮肤电导水平。这三个指数是在受试者穿着看喜剧电影的衣服时被测量的。电影结束后，受试者用四个强度级别(0、1、2和3)对他们的乐趣和快感进行了评价。利用疼痛指数，推导出基于多元回归模型的估计公式。将估计的强度与报道的强度进行了比较。估计的平均误差约为0.3，表明所提出的方法能够估计人类为娱乐和快乐而产生的情感强度。本研究的第二个目的是评价脑电的α波(8 Hz~13 Hz)在舒适性和不适性情绪上的差异，包括-1/fm波动、a波功率和功率流。受试者为16名成人，年龄20~23岁。将这些电极固定在国际10/20脑电系统中的FP_O_L 0_2上，进行1/f·m的波动分析。Fpl电极F_&lt；P_1&gt；、F_&lt；P_2&gt；、O_1、O_2的平均值：舒适情绪的m值大于不舒服情绪的平均值。这一结果与前人的研究结果一致。在功率分析中，舒适情绪和不舒服情绪在四个电极上没有显著差异，用自回归模型计算了从一个电极到另外三个电极的功率流值，实验结果表明，不舒服情绪的功率流平均值大于，F&lt；p1&gt；，F&lt；p2&gt；，O_1，O_2的功率流平均值较大。
