提出了一种将个性、情感、情绪分层表示的思想,并且利用贝叶斯网络进行情感建模,通过虚拟人脸的面部表情来反映情绪的变化,旨在赋予机器类人的情感,达到更加真实和谐的人机交互。最后将此情感模型应用于情感虚拟人交互系统,实验证明,该模型简单、稳定,且易于实现。 Proposed a thought of expressing personality, emotion and emotion hierarchically, and used Bayesian network to model emotion. It reflected the change of emotions through the facial expressions of virtual face, aiming at giving the emotion of humanoid machine to reach More real and harmonious human-computer interaction. Finally, the emotion model is applied to the emotion virtual human interaction system. Experiments show that the model is simple, stable and easy to implement.
