Psychologically grounded avatars expressions

Progress in computer graaphics over the last decade has ren- dered the creation of believable anthropomorphic graphical avatars pos- sible.

We explain how we created our animation on Scherer’s theory of emotion gener- ation associated with facial expressions to create five facial expression animations (happiness, disgust, sadness, fear and anger) that are con- gruent with Scherer’s theory. We discuss the specific steps and issues we followed as well as the evaluation results of a user study we conducted
