2. I.Background 1998 – Database “Lego” experimental assembly of an online event (Avatars98, Inside Cybespace)

3. I.Background Database assembly of space, but also database/agent operation: “booth bot”, “slide-changing bot”

4. I.Background NASA Needs: STS-61, Hubble Repair training (JSC 1993)

5. II. BrahmsVE Platform A virtual environment platform for discrete agent work practice simulation Begun in 1999, models of activities aboard Mars Analog Habitats FMARS and MDRS (SimHab) Humans and robotics in future mission concepts, modeled from captured habitat crew activities Backed by database/multi-agent system (Brahms)

6. II. BrahmsVE Platform Building “real-world” interfaces for a multi-agent work-practice simulator AgentViewer 2D interface Virtual Environment 3D interface

7. II. BrahmsVE Architecture High level components Web-based 3D player (Adobe Atmosphere) with AX components Javascript/SOAP, PHP and MySQL-based lightweight protocols Brahms, Java-based agent system 3D Content: XML schemas, Atmosphere/VP models, Havok physics Synchronized, multi-user collaboration, chat, voice

21. Conclusions Work is in an early stage development but based on a decade of prior work Use of lightweight web-distributed environments a significant development in collaborative modeling and simulation Development is much more rapid (10% compiled binary components, rest script and database) and agent and 3D models can be developed in a fraction of the time. BrahmsVE is funded to product introduction in the Fall of 2005 Seeking proof of concept projects (contact damer@digitalspace.com, 831 338 9400) damer@digitalspace.com
