2. Announcement of the Center The Center for Collaborative Technologies at the University of Washington will develop the ConferenceXP platform, apply the technologies to a wide range of educational and collaborative scenarios, and strengthen the educational and research communities that use these collaboration tools. The Center has been funded by Microsoft Research External Research and Programs for a period of three years. The Center is a collaboration between members of the University of Washington’s Department of Computer Science and Engineering, the Pacific Northwest Gigapop, and the ResearchChannel.
