In recent years, the automatic analysis of human behaviour has been attracting an increasing amount of attention from researchers because of its important applicative aspects and its intrinsic scientific interest. In many technological fields (pervasive and ubiquitous computing, multimodal interaction, ambient as-sisted living and assisted cognition, computer supported collaborative work, user modelling, automatic visual surveillance, etc.) the awareness is emerging that system can provide better and more appropriate services to people only if they can understand much more of what they presently do about users’ attitudes, preferences, personality, etc., as well as about what people are doing, the activities they have been en-gaged in the past, etc. At the same time, progress on sensors, sensor networking, computer vision, audio analysis and speech recognition are making available the building blocks for the automatic behavioural analysis. Multimodal analysis—the joint consideration of several perceptual channels—is a powerful tool to extract large and varied amounts of information from the acoustical and visual scene and from other sensing devices (e.g., RFIDs, on-body accelerometers, etc.). In this thesis, we consider small group meetings as a challenging example and case study of real life situations in which the multimodal analysis of social signals can be used to extract relevant information about the group and about individuals. In particular, we show how the same type of social signals can be used to reconstruct apparently disparate and diverse aspects of social and individual life ranging from the functional roles played by the participants in a meeting, to static characteristics of individuals (per-sonality traits) and behavioural outcomes (task performance).
