I am a computer scientist whose research interests include multimodal human-computer interaction (modeling and learning), computer vision, and pattern recognition. My research goals are to enable computers to sense the world from multiple cues, to understand these cues from learning, and to interact with humans in a natural way. My current research activities focus on developing technologies for three scenarios: (1) to support multimodal human computer interaction (e.g., Interact Project) and to serve humans who focus on interacting with other humans (e.g., CHIL Project); (2) to support geriatric care (e.g., CareMedia Project ); and (3) to support human collaborations (e.g., Gesture Project and Large Scale Collaboration Project ).
