The TeleHuman, as the technology is known, works with two people standing in front of their own cylindrical display video-conferencing pods. Each person communicates to holographic life-size 3D projections of one another. This image is visible 360 degrees around the pod and creates the illusion of another person standing within the pod.
"Why Skype when you can talk to a life-size 3D holographic image of another person?" said Roel Vertegaal, director of the Human Media Lab, on the Queen's University website.
