A teleconference or telecon is a live exchange of information among several people remote from one another but linked by a communications system.
The communications system may support the teleconference by providing one or more of the following: audio, video, and/or data services by one or more means, such as telephone, computer, telegraph, teletypewriter, radio, and television.
One key technology in this area is Voice over Internet Protocol (VOIP).
A working example of an augmented reality conferencing was demonstrated at the Salone di Mobile in Milano by AR+RFID Lab.
