The Research of Psychology Modeling Applied to Virtual Human

Using computers to simulate human affective activities is a challenging work. After the analysis of human affective characters, this paper puts forward some artificial psychology models and mainly discusses a model based on HMM, and the concept of affective entropy which is used as the parameter index of constructing and evaluating individual characters of virtual human. This model considers human affective procedure as a two layers stochastic process. The psychology models symbolized by individual affective characters can be constructed by adjusting the initial parameters in the model. As the affective engine, it also can be used to predict the final result of affective procedure in the form of probability. So it can be applied to the fields of virtual human、game、affective robots、humanized computing, etc.
