About

Dr. Lieu-Hen Chen is a distinguished researcher whose work bridges human-computer interaction, visualization, and affective computing. His key research areas include user-generated content analysis, nonverbal behavior recognition, and human-robot interaction. Dr. Chen made significant contributions by developing an interactive visualization system that clusters and displays user opinions from vast amounts of user-generated content, enabling rapid comprehension of emotional features without manual examination. This work, cited 4 times, addresses the critical challenge of information overload in social media analytics. In another highly cited study (4 citations), Dr. Chen pioneered the analysis of nonverbal behavior—such as gestures, facial expressions, and posture—to detect awkward situations during human-robot communication. This research advances the field of social robotics by enabling machines to recognize and respond to subtle social cues, improving the naturalness of interactions in public settings like marketplaces. His work is particularly notable for its practical applications in designing empathetic robots that can navigate complex social dynamics, laying groundwork for more intuitive and responsive AI systems in everyday life.
