The DFKI department Cognitive Assistants (COS) focuses on the development of basic principles of multimodal Human-Machine Interaction and personalized dialogue systems that integrate speech, gestures, and facial expressions with physical interaction. In the COS research group Human-AI Interaction we investigate the interconnections between applied AI technologies and UX. In our research and industry projects, we build conversational and multimodal dialogue systems for diverse applications in different domains.
