Networks not only facilitate but seem to mandate partnerships

  • CAVE Research Network (CAVERN)
  • CAVE Research Network User’s Society (CAVERNUS)
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
why represent people
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”
two representations of people
Two Representations of People
  • Video images
  • Synthetic models (avatars)
tele immersion and cavernsoft
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!

requirements for tele immersion
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
more requirements for tele immersion
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)

impact five years from now
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
international impact
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
