The knotty gestures is a simple yet powerful technique for interacting with paper. Knots are tiny circles that can be added to any gesture. Users can leave subtle marks that permit both immediate interaction in the flow of writing and create rich opportunities for future interaction. We have conducted two experiments to evaluate the design and recognition heuristics and demonstrated that people can successfully execute knotty gestures, even without feedback. Knotty gestures provide users with a subtle, in-the-flow-of-writing technique for tagging information and subsequently interacting with the paper. The current implementation of the technique has been based on Anoto technology and Livescribe pens.
Our work on interaction techniques for paper has been based on years of experience studying diverse groups of users, such as biologists , using paper.

We focus on the creative use of paper in the music composition process, particularly the interaction between paper and end-user programming. Working in close collaboration with composers and researchers at IRCAM, we have designed paper-based interfaces to help composers create their own, individualized composition languages and tools and to experiment with music, on-paper and on-line.

Reflecting on Personal and Collaborative Activity
We studied the evolving work practices of biologists and the role of paper and electronic laboratory notebooks to support their individual and collaborative activity. In a participatory design approach, combined with longitudinal field we tested Prism, a hybrid lab notebook for biologists to capture, visualize and interact with streams of activity.
Prism provides an interactive access to cross-linked activity streams: hand-written notes on paper, type-written notes on-line, and key points (web sites, emails, analysis results) from users' computer activity, as well as web based activity.We used Prism as an extensible technology probe that users could adapt to integrate additional streams and share information from other biologists. Our key findings include the notion of master documents, whether paper or electronic, and the importance of redundancy, which biologists use to make sense of their data. Prism provides a flexible, extensible tool that supports individual and collaborative reflection in creative work.

Sustainable Design with Reusable Paper
We explored the need for sustainable design with paper: how people really print and how we can take advantage of novel, reusable paper technology. We conducted two studies to investigate user's printing behavior. A key finding of the first study was that users often need an intermediate state between the electronic and physical forms of their documents. The second study examined users' predictions of which types of documents required this intermediate state. We formulated these findings into design guidelines that take into account: examination phase, transitions, cognitive and emotional reasons, and task- and event-relevant documents.
