My PhD work focuses on designing and evaluating digital pen applications. A digital pen contains a processor and a camera that can capture what a user writes on a physical surface, such as a sheet paper or a table. The goal of my research is to design and implement novel digital pen interfaces for paper-intensive domains such as design and architecture.
