Morgan Dixon mdixon@cs.washington.edu University of Washington Room 606 Paul Allen Center I am a second year Computer Science and Engineering Ph.D. student at the University of Washington, where I work with James Fogarty. I received my bachelors in computer science and mathematics from the University of Maryland. My advisor was Francois Guimbretiere. I am fortunate to be partially funded by ARCS. I am interested in Human-Computer Interaction and User Interface Software and Technology. I am a member of the DUB group. Here is a link to my CV. Projects and Publications Codex The Codex is a dual-screen tablet computer, about the size of a 4" x 6" day planner, with a self-supporting binding and embedded sensors. The device can be oriented in a variety of postures to support different nuances of individual work, ambient display, or collaboration with another user.

(PDF) (Video) Improved Electronic Reading Devices Ethnographers report that when reading, people frequently read from multiple display surfaces. We designed a prototype dual display e-book reader and explored how it can be used to interact with electronic documents. Chen, N., Guimbretiere, F., Dixon, M., Lewis, C., Agrawala, M.

ACM Press, New York, NY, 1779 - 1788. (PDF) Crossing-based Interfaces As Tablet PCs become more popular, it is important to better understand the characteristics of interfaces specifically designed for pen interactions. We explore crossing-based interfaces in which all interactions are performed by crossing targets on the screen. Namely, we provided optimized parameters for the space-speed trade-off that occurs in crossing interfaces and proposed a new crossing-based dialog box implementation based on our results.

(PDF) ExperiScope We presented ExperiScope, an analytical tool to help designers and experimenters explore the results of quantitative evaluations of interaction techniques. The tool makes it easy to identify and compare key patterns of use encountered during data collection.This promotes a deeper understanding of the results of a given evaluation.
