Summary of Collaborative VEs APIs,and applications developed at VT
Faculty VE and visualization projects (chronological order starting with the NSF ARI proposal)
UVAG
• Initially their where 29 CoPIs on the NSF white paper (1995) to build a CAVE, but more important, to build a VE-visualization group associated with ACITC (Torgersen Hall): (NSF-$890K) + ($530K: 5-Colleges, RGS, AIS). This seminar is about the people who came together as a group which will be the future Center for Virtual Environments and Visualization (CVEV).
• AtomView (1997): John Shalf (NCSA), R. Kriz, D. Farkas• CAVE Collaborative Console (1998): K. Curry, F. Das Neves, J. Kelso, M. Rosson, J. Carroll, and R. Kriz• CCC_atom (1999): G. Edwards, F. Das Neves, and R. Kriz• College of Architecture Viz Lab (1998): R. Schubert and D. Jones
• Interior Design Futures Lab (1998): J. McLain-Kark• Entomology (1998): A. Sharov and T. Mack• Extending CCC for K12 (1999): F. Neves and R. Kriz

Observations & Conclusions:
• Virtual and collaborative design environments have been at best working prototypes that are too difficult to use by the academic community.
• Better API’s are needed so that scientists, engineers, and educators can build their own applications based on the content within their discipline.
• The best designed collaborative environments will work only within existing collaborative groups
UVAG
VE-Viz Recommendations:• Identify researchers and educators who have experience in building collaborative applications and their associated APIs.
• Build a working collaborative design environment prototype API with participants identified above and select a specific research and educational demonstration project. Participants should include scientists and engineers depending on target application.• Include in the design a usability evaluation based on a “user-centered-design” philosophy.
University “BIG-Picture” Recommendations:• Differentiate between administrative computing and research & academic computing
• Draft a plan for research and academic computing
