Evaluation of Synthetic Faces: Human Recognition of Emotional Facial Displays

Abstract

Despite the growing attention towards the communication adequacy of embodied conversational agents (ECAs), standards for their assessment are still missing. This paper reports about a methodology for the evaluation of the adequacy of facial displays in the expression of some basic emotional states, based on a recognition task. We consider recognition rates and error distribution, both in absolute terms and with respect to a human model. As to data analysis, we propose to resort to standard loglinear techniques and to information-theoretic ones. Results from an experiment are presented and the potentials of the methodology are discussed
