Many on-line communities still rely on text messages as their privileged medium of communication and we believe it will remain so even if it can be complemented by images and video. Previous chapters have described how to infer emergent emotion dynamics from text corpus whereas we focus here on the instantaneous display of a detected emotion with a human avatar. The avatar acts as a new modality to provide an emotional visual stream of the messages through facial and body Non-Verbal Communication (NVC). In this chapter we concentrate on chat applications for which the time constraint is critical for preserving the natural flow of the discussion. We describe an efficient mapping of the Valence-Arousal-Dominance emotion model to real-time facial expressions. Within that framework, we stress the need for reconsidering the expressive power of asymmetric facial expression for better conveying a whole range of complex and ambivalent emotions. In the last section we briefly outline how the emotional avatar modality can be offered with recent software standards across systems and display environments.
