The Affective Computing Group (ACG) is an interdisciplinary team researching Social Human-Computer Interaction in various projects. The ACG is part of the Cognitive Assistants (COS) department of the German Research Center for Artificial Intelligence (DFKI). We believe that satisfying social interaction with technical devices should follow the principles of Human-Human interaction. Within that context, we focus on modeling human emotions, communication of emotions, behavioral patterns, as well as social norms and values.
