There has been widespread recognition of the existence of a gap between electronic data and paper data. Past techniques to solve this problem have met with little success, and have been largely focused around the desktop environment. In this paper we present PocketPad, a mobile application framework that supports the retrieval, and interaction with content in the digital world through Anoto-based pen and paper. The specific advantage provided by PocketPad is the repurposing of digital content through a human-in-the-loop port of electronic information stored in the repository onto a digital canvas. This electronic content is combined with strokes rendered on pen and paper, bringing the advantages of pen and paper and the flexibility of electronic content together in a mobile framework. We describe each application component, and their role in supporting mobile paper-based interaction. We also describe testing that studies the ability of subjects to perform visual spatial registration of Pocket PC-based content with pen and paper based content to validate the interaction supported by the PocketPad system.


Ed Lank has been an Assistant Professor in the Computer Science Department at San Francisco State University for the last three years, and a Research Assistant Professor (Fall 2005 semester) at the University of Waterloo . He will be joining the School of Computer Science at the University of Waterloo in June 2006 full-time as an Assistant Professor. Prior to joining the faculty at San Francisco State University , Lank was a research intern at the Palo Alto Research Center in the Perceptual Document Analysis Area; was Chief Technical Officer of MediaShell Corporation, a Queen's University research start-up; and was an Adjunct Professor in the Department of Computing and Information Science at Queen's University. Prof. Lank received his Ph.D. in Computer Science from Queen's University in Kingston , Ontario in 2001 under the supervision of Dr. Dorothea Blostein. He received his Bachelor's Degree in Physics with a Minor in Computer Science and a Diploma in Engineering from the University of Prince Edward Island in 1994.
