Effects of Damping Head Movement and Facial Expression in Dyadic Conversation Using Real-Time Facial Expression Tracking and Synthesized Avatars

Thursday, July 9th, 2009

Boker, S. M., Cohn, J. F., Theobald, B.-J., Matthews, I., Brick, T. & Spies, J. (in press) Effects of Damping Head Movement and Facial Expression in Dyadic Conversation Using Real-Time Facial Expression Tracking and Synthesized Avatars. Philosophical Transactions of the Royal Society B.

This article reports an experiment in which research assistants’ head movements and facial expressions were motion tracked during videoconference conversations, an avatar face was reconstructed in real time, and naive participants spoke with the avatar face. Research assistants’ facial expressions, vocal inflections, and head movements were attenuated at one minute intervals in a fully crossed experimental design. Attenuated head movements led to increased head nods and lateral head turns, and attenuated facial expressions led to increased head nodding in both naive participants and in confederates. The results are consistent with a hypothesis that the dynamics of head movements in dyadic conversation include a shared equilibrium.

(a) four facial expression (b) four attenuated facial expression.
