Emotions play a critical role in increasing the believability of virtual agents. The paper develops an emotion model of virtual agent using particle system and OCC model. To better portray emotions of virtual agents, emotional experience is reflected by two aspects, which are the outer emotion defined by the intensity of particles, and the inner feeling by the number of particles. Based on the perspective of psychic energy, the interactional effect of emotions is incarnated through particle motion. Simulation is done by using Matlab software, and the results show that the emotion model can simulate better dynamic process of emotion transferring and change spontaneously.
