Embodying models of expressive behaviour and learning with a biomimetic virtual infant

Face to face interaction is vital to social learning, however detailed interactive models which capture the richness and subtlety of human expression do not currently exist. As a step towards this goal, this paper gives an overview of the novel approach we are taking to develop BabyX, an experimental computer generated psychobiological simulation of an infant combining models of the facial motor system and theoretical computational models of basic neural systems involved in interactive behaviour and learning. These models are implemented in a novel modeling language for neural systems designed for animation and embodied through advanced 3D computer graphics models of the face and upper body of an infant. The system analyzes video and audio inputs in real time and generates autonomous animation through neurobehavioural models.
