A New Approach to Emotion Generation and Expression

This paper describes a new and flexible approach to emotion generation and facial mapping that forgoes emotions labelling and facial action units. A biologically inspired architecture of emotion that allows regulation of an agent emotions and behaviour is presented. The resulting emotions are expressed through a 2D animated character, representing a context-aware mobile tour guide, guiding visitors touring an outdoor attraction. We mapped three facial features: the eyes, the mouth and the eyebrows onto the arousal and valence dimensions where each dimension influences a facial feature more strongly than the others. The focus of this paper is on facial expression. We provide a review of related work, a description of our approach and finally concluding remarks.
