Abstract
A smile may communicate different communicative intentions depending on subtle characteristics of the facial expression In this article we propose an algorithm to determine the morphological and dynamic characteristics of virtual agent’s smiles of amusement politeness and embarrassment The algorithm has been defined based on a virtual agent’s smiles corpus constructed by users and analyzed with a decision tree classification technique An evaluation in different contexts of the resulting smiles has enabled us to validate the proposed algorithm
