Our work examines the link between head motion entrainment of interacting couples and human expert's judgment on certain overall behavioral characteristics (e.g., Blame patterns). We employ a data-driven model that clusters head motion in an unsupervised manner into elementary types called kinemes. We propose three groups of similarity measures based on Kullback-Leibler divergence to model entrainment...
This paper presents a computational study of head motion in human interaction, notably of its role in conveying interlocutors’ behavioral characteristics. Head motion is physically complex and carries rich information; current modeling approaches based on visual signals, however , are still limited in their ability to adequately capture these important properties. Guided by the methodology of kinesics...
Behavioral synchrony, or entrainment, is a phenomenon of great interest to psychologists and a challenging construct to quantify. In this work we study the synchrony behavior of head motion in human dyadic interactions. We model head motion using Gaussian Mixture Model (GMM) of line spectral frequencies extracted from the motion vectors of the head. We quantify interlocutor head motion similarity...
