The overarching goal of my research is to bring the ease of use of pen and paper interactions to computer interfaces. Pen and paper are an extremely versatile tool used extensively by knowledge workers when sketching new concepts, exploring a design space by quickly sketching several variations, brainstorming during a meeting, or simply proofreading documents. Pen and paper interactions are rapid, fluid, and almost transparent to the user. Unfortunately, work captured on paper is often difficult to transfer back into the digital world where powerful computational resources are accessible. Through my work, I have demonstrated that the ease of use of pen and paper interactions and access to digital resources can be smoothly bridged.
