  1. Low-Cost Telepresence at Technical Conferences Robert W. “Bill” Nelson; JPL; 818-393-5291; robert.w.nelson@jpl.nasa.gov David W. Scott (Scotty); NASA – MSFC EO50; 256-544-3226; scotty@nasa.gov

  2. Why Do This? $ Enrichment Potential Reason We Tried it in 2011 Suggested by a Reviewer Telepresence Isn’t Just Video! Goal: People on each end feel as if everyone’s present in one place … So let’s get past web-conferencing-with-talking-heads, eh?

  3. Setup for IEEE Aeroconf 2011 Facility’s Overhead Sound System Dell PC Laptop Windows XP USB HD Webcam Remote Controllable Pan-Tilt-Zoom Apple MacBook Built-in i-Sight Camera OS 10.6 Additions to Existing Assets USB camera Audio & Ethernet cables Internet VSeeConferencing Client

  4. A Little Audio Challenge-allenge-allenge Overhead Mic Built In To Camera D/A & A/D Conversion Delay A/D & D/A Conversion Delay Internet Transmission Delay ? x!#@ ~1.5 second round trip The Fix (if echo-canceling hardware/software not available) Bonus! – Independent of house sound systems. Audio from remote aimed away from mic P.S. Camera movement was LOUD to remotes, but silent to conference room.

  5. TelepresenceGeometry 101! In the diagrams that follow… Sightlines: Show panning angles to center lens on areas of interest, e.g, if remote participant wants to look folks in the eye. (Zoom lens!) Panning angles to capture area in lens field of view can be significantly less Primary area of interest Blue - - - - - for 2011 Green - - - - - for suggestions Secondary area of interest Always Orange - - - - - • Assumptions: • 2011 – One remote participant (‘cause that’s all there was!) • Suggestions – Up to 3 remote participants • Remote camera controls usually not shown. • Only 1 camera. (Better presence with more, but more complex and much easier to mess up.) • Abbreviations: • Hopefully obvious. Along the lines of IRP (In-Room Presenter), RV (Remote Viewer) • Something to Think About: • How to position windows so that participants can look as directly as possible into camera for benefit of those on the other end while still digesting the content of the windows?

  6. Remote Viewing Geometry at IEEE 2011 Charts Remote Viewer IRP/Aud In-Room Presenter Worked fairly well. Remote viewer discovered challenge related to both viewing and presenting: Audience Keeping one’s eyes looking into the lens is harder than it looks! (pun intended)

  7. Suggestions: In-Room Presenter, Remote Viewer(s) Conference Room Charts RV Remote Participant(s) – View or Don’t View? Driver = Level of Distraction If single remote, let remote control the camera. If multiple remote, have someone in the room drive – they can pick up room focus without “fishing”, can avoid joystick wars. IRP/Aud In-Room Presenter Bonus! How ‘bout a report “live from the scene”? Charts (App Share) IRP Remote Site RV Audience RV Self HD Camera View of IRP & Charts or RV RV Better “presence” from RV perspective if picture quality high

  8. Remote Presenting Geometry at IEEE 2011 Charts (App Share) RP Aud Audience Images are actually from panel discussion, but show good room coverage and zoom for Q&A Same glance-down issue as for remote viewing (Darn!)

  9. Suggestions: In-Room Viewers, Remote Presenter Conference Room Charts Aud Remote Presenter and Charts RP or Aud Better “presence” from Conference perspective if picture quality high Note who’s missing! Why? When balancing chart vs. participant window size, consider proportionality of talking heads. Remote Site Audience Self Audience Charts RV RV

  10. Panel Discussion Geometry at IEEE 2011 Charts RV IRP/Aud Remote Viewer challenges: Huge panning angle to see all panel members Inner panel member blocked outer member More panning to engage audience Audience

  11. Suggestions: Panel Discussions RP1 RP2 RP3 Either Room Configuration RP1 RP2 RP3 Charts P/A P/A or A bit more natural for audience Remotes still have to pan Screen Audience Ditch the charts if you can… It’s supposed to be a discussion! Panel/Aud RP2 RP2 RP3 RP3 Charts Panel/Aud Screen No panning for remotes to engage panel In-room panelists need to turn some to engage audience Self Self Remote Site 1, Either Room Configuration Audience or

  12. Cultural (Hence Habit) Issues ? o Conference o Traditional Augmented Poster Session E-Poster Hall T-Presence Hall A year or two Make it even richer! Don’t Lose ‘Em – Hook ‘Em! Keep Those Home Fires Burning

  14. Parting Thoughts Telepresence Principles = Pirates Code More what you call guidelines than actual rules Put people at the center! Thematically and physically Presence… The eyes have it! Help folks look directly “at” their colleagues Position windows to draw eye focus towards camera
