  21. 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. U V A G

  22. 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.
