1 What do these have in common?

2 Telepresence

3 Telepresence is like being there, only better Videoconferencing on steroids has potential to lessen your carbon footprint and your frequent flier miles.

4 This lecture contains marketing hype that I ll occasionally ridicule.

6 yeah, right!

7 telepresence ˈtel"ˌprez"ns the use of virtual reality technology, especially for remote control of machinery or for apparent participation in distant events.

8 telepresence ˈtel"ˌprez"ns the use of virtual reality technology, especially for remote control of machinery or for apparent participation in distant events. a sensation of being elsewhere, created by the use of virtual reality technology. Virtual presence

10 Some Applications! telecommuting! business meetings! telemedicine! distance education

11 And it always works, right?

12 Early imagination - The Telephot [Hugo Gernsback, Modern Electronics 1911] "At this moment the voiced ceased and Ralph's faceplate became clear. Somewhere in the Teleservice company's central office the connection had been broken. After several vain efforts to restore it Ralph was about to give up in disgust

13 Videoconferencing: the past [AT&T PicturePhone 1956]

14 Heilig s Sensorama [1957]

15 PicturePhone [AT&T 1970s]! faster, smaller, portable, cheaper! videoconferencing conceptualized as direct replacement for face-toface meetings (and the telephone)

16 Cisco Telepresence [2006]

19 Simply walk in and start collaborating as if you were sitting across the table in the same room...and experience clarity so realistic, you will forget you are thousands of miles apart.

21 So does it really feel like I m there?

22 [ ] What are the computing and telecommunication requirements needed to support a sense of group telepresence among separated workers?"

23 Would you want this on your desk all day long?

24 Background Activity Awareness background awareness provided by periodic snapshots of distributed group members

25 Placement of Video Avatars

26 Door Avatar

27 Privacy considerations

28 Physical Door = On-line Status! physical door state determines video accessibility! reinforces sense of shared space

29 Hydra! preserves spatial relationships! ensures gaze awareness! combined footprint of 3 devices < desk telephone

31 Limitations of Media Space! video conference is not like real life! limited field of view, resolution, 3D info! spatial discontinuities, fixed orientation...active exploration is crucial for interaction J. J. GIBSON

38 Distance and Delay New York-Ottawa (500 km), Remote Masters class, Dec. 8, 2000 Pinchas Zuckerman, Columbia U, NYC Wu Ji, Canarie ARDNOC, Ottawa *used Litton MPEG-2 10 Mbps

39 Expected Latency for Musical Performance acceptable telephony 1 actual H idealized MPEG 2 acquire compress (typical videoconferencing systems) transmit ms light speed: Montreal-LA light speed: anywhere on earth uncompressed video 1. ITU standard G.114 for acceptable conversation quality. 2. Includes only buffering time for one frame of NTSC video, as required for forward frame prediction, and assumes zero encoding and decoding delay. 3. Average measurement of Apple ichat on a local 1 Gbps connection; Xmeeting (H.264) obtained latency of 140 ms with significantly degraded quality; a Polycom (H.263+) hardware unit yielded measurements of 255 ms latency.
