• 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
Classroom Presenter
• TabletPC-Based Distributed Presentation System
• Instructor navigation and annotation on local and
remote displays
• Open Source License

Classroom Activities
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
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
