Effects of damping head movement and facial expression in dyadic conversation using real-time facial expression tracking and synthesized avatars

<26> Investigating the affect of expressiveness on behaviour in face-to-face interactions once required the recording of actors who simulated conversational styles. Inevitably these conversations are unnatural and compromise studies that make use of them. Our system allows natural conversations conducted over a video-link to be used. Faces are tracked and re-synthesised using a model, but prior to display, the degree of expressiveness can be manipulated. This is achieved without either conversant being aware of the manipulation and so their underlying behaviours are entirely natural. No previous studies could use real and natural data in this way.
