A Dynamic Emotion Representation Model within a Facial Animation System

This paper presents a Dynamic Emotion Representation (DER) model, its implementation and an instance of a full humanoid emotional model built with it. The DER model has been implemented to enable users to create their own DER. The instance of the DER model described in this paper represents three types of emotions, primary, secondary emotions and mood. The design of this DER is discussed with reference to emotion theories and to the needs of a facial animation system in which it is integrated. The DER is used in our Emotionally Expressive Facial Animation System (EE-FAS) to produce emotional expressions, to select facial signals corresponding communicative functions in relation to the emotional state of the agent and also in relation to the comparison between the emotional state and the intended meanings expressed through communicative functions.
