Conversational and Interactive Agents
CONVERSATIONAL AND INTERACTIVE AGENTS
For a human to have real-time conversations with intelligent (virtual) agents, at HMI, we jointly address three aspects: behavior sensing, modeling and generation. Using computer vision and speech technology, we observe the human conversational participant’s body and head movements, facial expressions, and paralinguistic vocalizations. We detect social cues, which are informative of the stance and intentions of the participant. These are used to model the interaction, and to generate the agent’s appropriate conversational behavior. Our research combines corpus-based analysis with pattern recognition, multimodal behavior realization, and perceptual evaluation.
