  2. CAVE Research and Development 1992—Prototype CAVE 1993—10’x10’x10’ CAVE 1994—SIGGRAPH VROOM 1995—I-WAY at SC’95 1997—100 CAVES and derivatives worldwide 1997-8—NSF funding for CAVERN and new desktop VR devices for the Grid, STAR TAP and NCSA

  3. Electronic Visualization Laboratory (EVL) • 25 years at UIC • Joint program: EECS and Art & Design • 2 directors and 12 associated faculty • 10 staff • 50 graduate students (27 EVL supported) • Long-time application collaborations • National Center for Supercomputing Applications (NCSA) • Argonne National Laboratory • Building the Grid together

  4. EVL Computing and Networking Facilities • 4 CAVE-sized Onyx rack computers • 2 CAVEs, 8 ImmersaDesks, many workstations, at EVL and allied UI labs • OC-3 networking to MREN, vBNS, and STAR TAP • Access to the Grid: Very large SP2s, SGI’s at Argonne and NCSA and >100 CAVEs and ImmersaDesks worldwide

  5. The Grid:Blueprint for a New Computing InfrastructureI. Foster, C. Kesselman (Eds),Morgan Kaufmann, 1999 • ISBN 1-55860-475-8 • 22 chapters by expert authors including Andrew Chien, Jack Dongarra, Tom DeFanti, Andrew Grimshaw, Roch Guerin, Ken Kennedy, Paul Messina, Cliff Neuman, Jon Postel, Larry Smarr, Rick Stevens, and many others “A source book for the history of the future” -- Vint Cerf http://www.mkp.com/grids

  9. CAVERN Networks not only facilitate but seem to mandate partnerships • CAVE Research Network (CAVERN) • CAVE Research Network User’s Society (CAVERNUS)

  10. Tele-Immersion • Tele-Immersion is the merger of VR worlds and people--3D phone calls! • For each user, Tele-Immersion needs to support: • Viewer-centered perspective • Large angle of view • Stereo • Seeing and talking to distant collaborators

  11. Why Represent People ? • Need to know relationship of people to synthetic world • To signal exchange and shared control • To communicate states of collaborators • To recognize people and tell who is talking • And, people want to be “in the picture”

  12. Two Representations of People • Video images • Synthetic models (avatars)

  13. Tele-Immersion and CAVERNsoft • Tele-Immersion requires expertise in graphics, VR, audio/video compression, networking, databases • Rapidly build new tele- immersive applications • Retro-fit old applications • CAVERNsoft enables applications!

  17. Requirements for Tele-Immersion • Collaborative interaction and manipulation • Communication: audio, video & avatars (virtual participants) • Synchronous and asynchronous work • Network and database quality of service • Multiple heterogeneous data streams

  18. More Requirements for Tele-Immersion • Flexible connectivity • High level modules for developers • Performance monitoring • Recordability • Trans-oceanic capability • Cultural sensitivity (e.g., avatar gesture translators)

  22. iGrid: The International GridResearch Demonstrations, SC’98 • 22 demonstrations that featured technical innovations and application advancements requiring high-speed networks, with emphasis on distributed computing, tele-immersion, large datasets, remote instrumentation, and collaboration • 10 countries: Australia, Canada, Germany, Japan, Netherlands, Russia, Singapore, Switzerland, Taiwan, USA

  23. International Applications-Level Networking Issues • Building relationships • Time zones • Asynchronous collaboration • Annotations and recording • Network speeds / QoS needs • Speed of light • Audio • Culture

  29. Impact: Five Years From Now • Tele-immersion and data mining over high speed networks will be routine; audio, video, gesture and haptics will be integrated with latency tolerant techniques • Methods for recording, editing, annotating, replaying, and broadcasting tele-immersive sessions will be perfected; avatars will help convey a true sense of tele-presence

  30. International Impact • Tele-immersion is particularly critical for trans-oceanic science and engineering users • Implementation is particularly difficult and challenging as distance increases • Significant participation expected by international researchers via STAR TAP, given support for applications development
