Social Signal Processing
Non-verbal behavior, including but not limited to gaze, facial expression and body language, is extremely significant in human interaction. In the analysis of group behavior some key variables are the proximity and focus of attention indicating the object or person one is attending to. We apply computer vision monitoring in combination with other sensing modalities (e.g. audio) to explore the relationship between proxemics, visual attention, social signals and personality traits during interaction.
