Paper has been repeatedly recognized as an important medium for exchanging, editing and managing documents throughout the document life-cycle. Despite their static nature, paper documents still represent one of the preferred way of handling information in different situations, such as in office environments, on the move or in collaboration. In order to overcome the limitations of paper and exploit the advantages of digital interfaces, new technologies for interactive paper have been introduced in recent years. Technologies such as the Anoto Digital Pen and Paper enable users to access digital information through interactions with printed copies. Links to digital content and services are defined on paper and activated when users interact with the paper sheet by means of a digital pen.

We are exploring a range of different Paper-DIgital interactions that aim at better integrating Paper documents with digital services and appications. As Sellen and Harper describe in their book "The Myth of the Paperless Office"

"Rather than pursue the ideal of the paperless office, we should work toward a future in which paper and electronic document tools work in concert and organizational processes make optimal use of both."

In our research we look at Paper-Digital Interactions in a variety of domains, such as healthcare, online social networks, observational research, interaction with wall displays, and augmented office environments, and we study how to best integrate digital aids and paper documents to better support the specific everyday activity.
