I'm currently a grad student here at the SIMS program in Berkeley working with Marc Davis and Peter Lyman. I recently interned at HP Labs in Bernardo Huberman's Information Dynamics Lab. Before that I was at PARC (formely Xerox PARC) in Marc Steffik's Human Document Interaction Group. Before that I was at the University of Minnesota working with Joe Konstan and John Reidl in the Grouplens group.
Focus + Context Screens
I worked as a long term intern at Xerox PARC for the year of 2001. I was with the Human Document Interfaces (HDI) group and my mentor was Patrick Baudisch and Mark Steffik. We created the focus and context screen, a display with a high resolution center and low resolution periphery. It offers a seamless connection between the two different displays, such that they are perceived as one single image from the users perspective. The idea behind it is that you can have create large single users displays which allocate more pixels to the high-res fovea region of the human eye and less pixels to the periphery. It got some press from the New York Times here and photos of our CHI demo are here.
I got my BSCS from the University of Minnesota Computer Science Department. There I had the privilege of working with two great professors who helped get me started with all this research stuff, John Riedl and Joe Konstan.
MovieLens
At the university of Minnesota, I worked on Filterbots with the Grouplens group and helped with implementing Movielens in the early days (http://www.movielens.org/) . MovieLens is a system that recommends movies based on similarities in user preferences using automated collaborative filtering. Filterbots are artificial autonomous agents that are included in a collaborative filtering system to improve recommendation quality by incorporating meta-data and content analysis to alleviate problems that come from sparse data sets and improve the quality of recommendations.DBLens Public Domain Software
I worked with a graduate student, Jon Herlocker, developing and using our Oracle based, free collaborative filtering system. It allowed us to play with different algorithms and see exactly what is happening with our collaborative filtering system when we tweaked things, which we couldn't do with the Net Perceptions server. DBLens is now on source forge (http://sourceforge.net/projects/dblens/).MovieLens Press links
Our Movielens project was extremely successful and gained a great deal of national publicity, as well as a large persistent user base of thousands of users. Most notably we were the subject of an ABC Nightline (http://abcnews.go.com/sections/nightline/index.html) episode called decoded by computer (Dec 10 1999) and the subject of a New Yorker article on technologies to overpower the blockbusters (http://www.gladwell.com/1999/1999_10_04_a_sleeper.htm). We have also been featured in the Wall Street Journal, as well as various local papers and magazines.
These are the slides of the talk I gave to interview at PARC. They are based largely on the slides of the talk we gave at AAAI 99.
This is a slightly more brief, less technical version given to MGM movie executives and web developers who came to Minnesota to see what we were doing.
