My research focuses on the design of workspaces and devices that augment face-to-face interaction. Much of my work is situated in the context of augmenting medical, therapeutic, and educational interaction. I have a line of research on assistive and educational uses of surface computing. This includes research on how a surface computer supports medical communication between a doctor and patient. Some of my recent work investigates how multimodal paper-digital interfaces support communication and language learning in home, school, and therapy settings.
