21. UVAGUVAG Observations & Conclusions: Virtual and collaborative design environments have been at best working prototypes that are too difficult to use by the engineering design community. Better API’s are needed so that scientists and engineers can build their own applications based on physics and content. The best designed collaborative environments will work only within existing collaborative groups, otherwise the culture must change to reward collaborations not competition.

22. UVAGUVAG Recommendations: Identify key ONR researchers who have experience in building APIs, who also have advanced degrees in the sciences and engineering with an emphasis on design. Build a working collaborative design environment prototype API with participants identified above and select a specific design application as a demonstration project. Perform a usability evaluation, upgrade-modify API and improve on demonstration collaborative design application.
