Upon entering the station, each participant is given a small wireless sensor that monitors his or her exact three-dimensional position. Presented on the giant screen on the ceiling are interactive animations of a ring and a disc which make low drones as they float around the screen. Conversely, the disc follows the sensor in the remote station, so that the local participant can infer the displacements of the other participant through the movement of the disc. The blue beams point to the local participant, while the yellow beams point to the position of the remote participant. The point of intersection of the yellow beams corresponds to the exact position of the sensor in the remote station.
Fog machines accentuate the light beams.
Ten speakers distributed around each station broadcast sounds that seem to originate from the relative position of the remote participant. For instance, if a participant moves to the right, the other participant hears the sound also moving in that direction. Similarly, the sound becomes louder as one approaches the other participant. Each station has a giant monitor that presents statistics, messages and graphics designed to give the participants quantitative information about their movements. The presence of the remote participant is ghostly and mysterious since one knows nothing about him of her, except for his or her three-dimensional movement.
