Users of the remote-communication HyperMirror feel as if they are looking into a mirror that displays both their remote selves and anything in the background as an integrated, single image. One user looked by reflex toward the "real" speaker when this speaker started to explain the system. The user soon realized, however, that this was remote communication and turned to the HyperMirror. It took just a second to understand what was happening, clearly demonstrating the "reality" of communication through the HyperMirror even when users understand a virtual image is involved in such remote communication.
