A Personality Based Emotion Model for Intelligent Virtual Agents

Modeling intelligent virtual agent is a new research field that integrates artificial life and computer animation together. A believable virtual agent should have personality, motivation, and emotion. Personality is an important characteristic for a virtual agent, the relative researches on intelligent agents are summarized, and the formal definitions for personality and emotions are presented in fuzzy set theory. A computational model of emotion is set up, inner motivation variable and outer stimuli variable can drive the trigger of a basic emotion, the quantitative relations among personality, motivation, and emotion are proposed. The result shows that a virtual agent with different personality variables may express an emotion or not.
