A grand challenge shared between computer science and communication technology is reproducing the
face-to-face meeting across a distance. At present, we are some way from reproducing many of the
semantics of a face-to-face meeting. Furthermore, while we can reproduce some in certain mediums
and others in others, we are currently unable to reproduce most in any.
This tutorial begins by explaining some of the primary challenges in reproducing the face to face
meeting and goes on to showing how our research is examining both the problems and solutions. We
compare the approaches of "telepresent" video conferencing, immersive virtual environments, and 3D
video based tele-immersion.
A central theme is the communication of appearance and attention. We explain why video conferencing
can only faithfully reproduce the first while virtual reality only the second, and how close free
viewpoint 3D video is coming to doing both. We look at tracking technologies for driving avatars,
ranging from from eye-trackers to the Kinect, and various ways of capturing people with multistream
video and reproducing them in 3D video.
