We are interested in enabling natural human-computer interaction by combining techniques from computer vision, machine learning, computer graphics, human-computer interaction, and psychology. Specific areas that we focus on include: multimodal human-computer interfaces, affective computing, pen-based interfaces, sketch-based applications, intelligent user interfaces, applications of computer vision and machine learning to solving real world problems.
