  2. Outline • Project Overview: Goals & Challenges • Technology Employed • ConferenceXP • Classroom Presenter • Findings and Lessons Learned

  3. Seattle – Pakistan, Spring 2008 • Masters Level Computer Science Class • University of Washington • Lahore University of Management Science • Microsoft • Class Topic: “Computing for the Developing world”

  4. The Goal Achieve an interactive class across distance and culture

  5. Challenges/Benefits • Challenges • Network bandwidth and latency to LUMS • Important not to degrade experience for UW & Microsoft students • Time zone • Benefits • Engaged faculty member present at LUMS • International perspective of high value

  6. ConferenceXP • Platform for real-time collaboration • High quality, low latency multipoint conferencing • Targeted for standard PC and high quality network • Works with commodity cameras and audio equipment • Built-in collaboration tools including presentation, whiteboard , screen sharing, video playback, chat

  7. IIIT Bangalore

  8. Overview of ConferenceXP • Began at Microsoft Research in 2001 • Numerous successful deployments for distance learning, 2003-present • UW Center for Collaborative Technology established July 2007 to continue project • Shared Source License: Free download for Research & Educational use

  9. Classroom Presenter • TabletPC-Based Distributed Presentation System • Instructor navigation and annotation on local and remote displays • Open Source License • Students contributed to class using digital ink • Students installed software on their laptops/tablets • Instructor reviewed/displayed/annotated/discussed student work • Promotes active learning

  16. Classroom Activities

  17. Project Results • High connectivity 9 out of 10 classes • One lecture originated from Pakistan • Only failure was on the UW-Microsoft Link (which also brought down UW-Pakistan) • Some early audio issues • Participation of students from Pakistan • Student activities were a positive factor • Audio latency a negative factor • Multiple rounds of audio communication

  18. Key Lessons for Deployment • Participants at all sites must have incentive • Instructor must make an effort to create multisite interaction • Active participants at remote site help • Audio is very important, and hardest to get right • Time zones and scheduling are major issues
