Abstract: To equip the Agent with emotions, enhance its fidelity and natural interaction with human beings and to satisfy the real-time requirement in intelligent virtual environment, according to basic emotion theory and cognitive evaluation theory in psychology, an emotion model based on fuzzy rules was proposed. Firstly, "emotion factor" was generated according to the emotion elicitation rules based on fuzzy IF-THEN rules. Then a nonlinear function restricted by personality, emotion factor and emotion state at the previous moment were used to compute emotion strength. The simulation result shows that this model can simulate the fuzzy and nonlinear characteristic of human emotion to a certain extent, and more importantly, it is easy to realize by computer program.
