Real-time social interaction analysis

This demonstration presents a social interaction analysis system designed to operate in real-time and under real environment conditions. A webcam is used to capture videos of a group of people interacting in an unconstrained environment. Locations of multiple people and their head poses are extracted from the videos. Direct pairwise interactions are detected based on the relative distance and head orientation using a probabilistic model. Communicative behavior analysis is carried out by grouping people based on their interaction patterns, i.e. frequency and duration, among the social group.
