  2. Presentation • Summary of collaborative virtual environments (VEs), • application program interfaces (APIs), and applications • developed at Virginia Tech • Future development of collaborative VEs U V A G

  3. Collaborative APIs: EVL’s CAVERNsoft: Limbo / Tandem VT’s DIVERSE Chronology: Collaborative VEs atVT AtomView (NSF PACI: NCSA-VT) Limbo Apps: CAVE Collaborative Console (CCC) CCC_atom (CCC + AtomView) DIVERSE Apps: Physics Based Simulations Crane-Ship (ONR-DURIP) Haptic Feedback - Molecular Docking (ASPIRES) NUWC’s CONRAY Undersea Warfare (ONR-NavCIITI) NIST’s RAVE: SmokeView Lockheed Martin: Collaborative Engineering Design Summary of Collaborative VEs APIs, and applications developed at VT U V A G

  4. 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.” !!! IDEA !!! The CAVE desktop simulator allows desktop-to-desktop collaborative design with a fully immersive option U V A G

  32. 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.
