  1. Data-Driven Virtual Environment Assembly and Operation Virtual Iron Bird Workshop – Naval Postgraduate School(04/02/2004) I. Background II. BrahmsVE Platform III. BrahmsVE/SimStation Online

  2. Background1998 – Database “Lego” experimental assembly of an online event (Avatars98, Inside Cybespace)

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

  4. BackgroundNASA Needs: STS-61, Hubble Repair training(JSC 1993)

  5. II. BrahmsVE PlatformA 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 PlatformBuilding “real-world” interfaces for a multi-agent work-practice simulator • AgentViewer 2D interface • Virtual Environment 3D interface

  7. II. BrahmsVE ArchitectureHigh 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

  8. II. Architecture of BrahmsVEInternal engine fundamental building blocks

  9. II. BrahmsVE/SimHabModeling process • Video and other activity capture • Brahms agent model • Geographic model: waypoints • Object, gesture and agent 3D models

  10. II. BrahmsVE/SimHabExample: planning meeting

  11. II. BrahmsVE/SimHabExample: EVA prep

  12. II. BrahmsVE/Personal Satellite AssistantExample: PSA aboard ISS with astronaut-agents NASA ISS PSA Design SimulationA robot assistant aboard the Space StationHuman Centered Computing (HCC) project

  13. II. BrahmsVE/PSA – web interface

  17. III. BrahmsVE/SimStation Online Online Instance of SimStationA rendition of SimStation project of Shirley, Cochrane et al,goals for online collaboration and document linking,early development phase

  18. III. BrahmsVE/SimStation Online • Web-based plugin (Adobe Atmosphere) with PHP/MySQL and Constructor parses XML component connection model to assemble station, components link to: • online documents • close-out photography • video • Notations • multi user collaboration • voice loops • Future: construction/EVA viz

  20. III. BrahmsVE/SimStation OnlineWeb architecture

  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)
