中文摘要：

为了准确识别人机交互中体态语言的情感态度,提出了基于表面肌电的头部运动情感识别模型.针对自发表达“同意”与“不同意”态度的点头与摇头动作招募了8名被试,分别采集颈部头夹肌、胸锁乳突肌和斜方肌的表面肌电信号,通过单因素方差分析提取了这2种情感态度具有显著性差异的10个肌电时域特征向量,将其作为模型的输入变量;再利用Elman神经网络建立点头与摇头的情感识别模型;最后将该模型与基于BP神经网络和支持向量机的情感识别模型进行性能比较.实验结果表明,对测试集中“同意”与“不同意”情感态度的准确识别率超过96％,从而验证了文中模型的可靠性.

英文摘要：

To recognize emotional attitudes of body language accurately in human-computer interaction, a surface electromyography based emotion recognition model of head movements is proposed. Aiming at analyzing attitudes of agreement and disagreement expressed spontaneously by nodding and shaking head, we recorded the surface electromyographic signals from splenius capitis, sternocleidomastoids and trapeziums of 8 participants. Using one-way domain parameters, with significant differences ANOVA, 10 features of electromyographic time between two attitudes, were extracted as input parameters. The emotion recognition model of head nodding and shaking was constructed using Elman neural network. Finally, the performance of the model was compared with other two emotion recognition models using BP neural network and support vector machine. Experimental results show that correct recognition rates of our model on the test set with agreement and disagreement emotional attitudes are more than 96 %, which demonstrates the reliability of the presented model and method in this paper.
