  33. 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. U V A G

  34. 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. • Perform a usability evaluation, upgrade-modify application • and associated API. U V A G
