Common collaborations
• Work very closely with a small number of people
• While the composition may change over time, the location of collaborations stays pretty constant– Between two departments– Between two research groups at
different universities
![Page 8: SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN The Connection Project: Supporting Collaboration at The University of Michigan with High Quality Video Links](https://reader036.vdocuments.us/reader036/viewer/2022062515/56649f475503460f94c6903b/html5/thumbnails/8.jpg)

The Connection Project
• A project to leverage cyberinfrastructure in supporting the real-time collaboration needs of groups
• Emphasis on high-quality, high-bandwidth technologies
• Emphasis on connecting established sites together

Today’s talk
• Who needs this kind of stuff? • Why a new solution?• What we’ve done• How did it work?• Where are we going next

The School of Information is a natural laboratory for collaborative technology
experimentation.

Room use
• Meeting rooms used primarily for formal meetings
• More used by faculty than by staff– Staff opted to travel
• When not connected to remote sites, rooms frequently used for long work sessions

Do we need new solution?
• Is video quality sufficient to support large groups of people?
• Are the ergonomics correct in existing setups?
• Are training materials sufficient to encourage use?

User support
• As in many facilities, users were left with a set of instructions on the table to operate the system
• The instructions were good, but generally weren’t read
• Administrative assistants became the first line of support because they were closest

We wanted to do better.

Design Goals
• Improve video and audio quality– Leverage investments in campus
infrastructure
• Support high interactivity between sites– Natural interaction– High degree of gaze awareness
• Improve usability of the rooms• Also wanted to understand the impact
of the system upgrades

Facility Upgrade
• Dual 50” NEC Plasma Displays• Polycom VSX 7000• DVTS (beta trials)• NCast Telepresenter G2
• Table replacement

Documentation and training• Documentation process centered
around user testing– Many iterations with technical and non-
technical users
• Produced full-color print documentation• Produced a training video• Conducted training sessions with key
faculty and staff members

Some findings
• Users report that the improved audio and video quality makes the rooms a viable alternative to travel between sites.
• Users report that DVTS feels more “live” and the additional quality makes the experience more compelling

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN
Some findings
• Despite a nearly equal split of personnel between sites, meetings typically don’t include an equal number of people at each site– Design implications for future
facilities
![Page 29: SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN The Connection Project: Supporting Collaboration at The University of Michigan with High Quality Video Links](https://reader036.vdocuments.us/reader036/viewer/2022062515/56649f475503460f94c6903b/html5/thumbnails/29.jpg)
SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN
Some challenges ahead
• Organizational challenges still play a major role– Scheduling / character of use– Access issues
• While bandwidth is over-provisioned now, it’s unclear how much we can scale up use of DVTS in the future as other high bandwidth technologies come online

Work in progress
• Production integration of DVTS• HD Experimentation• Integration with network monitoring
technologies to support quality prediction and a dynamic capability set
• Social network analysis of organizational impact
• Controlled studies of video quality
