  • Dynamic Emotion Representation

    • A Dynamic Emotion Representation Model Within A Facial Animation System

      Abstract:This paper presents a Dynamic Emotion Representation (D.E.R.) model, its implementation and an instance of a full humanoid emotional model built with it. The D.E.R. model has been implemented to enable users to create their own D.E.R. The instance of the D.E.R. model described in this paper represents three types of emotions, primary, secondary emotions and mood. The design of this D.E.R. is discussed with reference to emotion theories and to the needs of a facial animation system in which it is integrated. The D.E.R. 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.

    • A Layered Dynamic Emotion Representation for the Creation of Complex Facial Expressions

      Abstract: This paper describes the Dynamic Emotional Representation (D.E.R.): a series of modules for representing and combining the many different types and time-courses of internal state which underly com- plex, human-like emotional responses. This system may be used either to provides a useful real-time, dynamic mechanism for animating emo- tional characters, or to underly the personality and action-selection of autonomous virtual agents. The system has been implemented and tested in a virtual reality animation tool where it expresses different moods and personalities as well as real-time emotional responses. Preliminary results are presented.
