Understanding how people exploit nonverbal aspects of their communication to coordinate their
activities and social relationships is a fundamental scientific challenge. Deeper insights into
nonverbal communication can have a profound impact on how we link theories of perception, learning,
cognition and action to models of interactions and groups at the social level. Models of nonverbal
behaviors in interaction are essential for collaboration tools, human-computer and virtual
interaction and other assistive technologies designed to support people in real-world activities.
This knowledge is also useful to develop models of the deficits of specific populations, such as
autistic children, and interventions that bring them into fuller participation in communities. In
general, nonverbal communication research offers high-level principles that might explain how
people organize, display, adapt and understand such behaviors for communicative purposes and social
goals. However, the specifics are generally not fully understood, nor is the way to translate these
principles into algorithms and computer-aided communication technologies such as intelligent
agents.
To model such complex dynamic processes effectively, novel computer vision and learning algorithms
are needed that take into account both the heterogeneity and the dynamicity intrinsic to behavior
data. As one of the most active research areas in computer vision, human motion analysis has become
a widely-used tool in this area. It uses image sequences to detect and track people, and also to
interpret human activities. Emerging automated methods for analyzing motion have
been studied and developed to enable tracking diverse human movements precisely and robustly as
well as correlating multiple people's movements in interaction. Some of the applications of using
motion analysis methods for Nonverbal Communication Computing include deception detection,
expression recognition, sign language recognition, behavior analysis, and group activity
recognition.
