Abstract: 

This paper focuses on the development of an expressive virtual storyteller for children and raises the challenges encountered to endow a virtual agent with storytelling capabilities. We focus on facial expressions of emotions and we present our computational model based on an appraisal theory of emotion. We also discuss different viewpoints a storyteller can adopt to evaluate the expressive content of a story event. We describe a preliminary study that we conducted with 23 children. We discuss the impact of facial expressions of appraisals on children’s memorization of story events, their perception of characters’ appraisals, their subjective perception of the virtual storyteller and more generally how emotion combines with joint attention.
