摘要
情感模型的建立可以使计算机具备基本的情感识别和表达能力,在和谐人机交互方面有着广泛的应用。文中借助于Picard教授关于情感计算的理论,将线性系统理论和数字信号处理方法应用到情感信号与系统建模上,用信号很好地表示了人类的内在情感和情绪,并通过MATLAB仿真实验分析证明了模型的正确性。最后结合情感的高层次认知推理机制,将情感模型应用到情感虚拟人当中,形象地实现了情感对人脸表情变化的控制。
Emotional model of the computer can meet the basic emotional identification and presentation skills, and man-machine interaction in a harmonious have a wide range of applications. It has the aid of Picard Professor＇s affective computing theory, applying the linear systems theory and digital signal processing to the emotional signals and system modeling, using signal to express the inner human feelings and sentiments finely, and through MATLAB simulation analysis proves the correctness of the model. Finally Combining emotional high-level cognitive reasoning mechanism to apply the emotional model to the virtual human, and achieving the control of the emotion to facial expressions＇ changing.
