Abstract

During dyadic interactions, participants adjust their behavior and give feedback continuously in response to the behavior of their interlocutors and the interaction context. In this paper, we study how a participant in a dyadic interaction adapts his/her body language to the behavior of the interlocutor, given the interaction goals and context. We apply a variety of psychology-inspired body language features to describe body motion and posture. We first examine the coordination between the dyad's behavior for two interaction stances: friendly and conflictive. The analysis empirically reveals the dyad's behavior coordination, and helps identify informative interlocutor features with respect to the participant's target body language features. The coordination patterns between the dyad's behavior are found to depend on the interaction stances assumed. We apply a Gaussian-Mixture-Model-based (GMM) statistical mapping in …
