“The goal of this project is to demonstrate that the CAVE Simulator, when combined with Limbo and CCC awareness tools can be used to deliver a collaborative virtual design environment with an emphasis on HCI and usability.”

!!! IDEA !!! The CAVE desktop simulator allows

desktop-to-desktop collaborative designwith a fully immersive option

What is a CAVE?

UVAG

Viewer immersed In 3D-structure. Gives viewer unique perspective to study

3D structure / property relationships.

Observations & Conclusions:

• Virtual and collaborative design environments have been at best working prototypes that are too difficult to use as a day-to-day application.

• 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.
