Extending the Use of Collaborative Virtual Environments to Engineering Design Using High Speed Networks Lockheed Martin University Grant Program Pat McKenzie Lockheed Astronautics Denver, Colorado “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.” UVAGUVAG !!! IDEA !!! The CAVE desktop simulator allows desktop-to-desktop collaborative design with a fully immersive option

UVAGUVAG 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.
