Improved Visual Focus of Attention Estimation and Prosodic Features for Analyzing Group Interactions

Collaborative group tasks require efficient and productive verbal and non-verbal interactions among the participants. Studying such interaction patterns could help groups perform more efficiently, but the detection and measurement of human behavior is challenging since it is inherently multimodal and changes on a millisecond time frame. In this paper, we present a method to study groups performing a collaborative decision-making task using...
