May the Force/Boss Be With You, in 3-D
"A Dallas company, Teleportec, has introduced technology to transmit holographic images of people over high-speed digital circuits. A chief executive can stand at a lectern in New York, for instance, while a three-dimensional, life-size image of him is projected onto a stage in San Francisco. The executive can remotely see the audience, and the participants on both sides of the transmission can communicate in real time.
"The optical portion of your brain insists the person is in the room because he meets all the criteria," said Philip Barnett, a vice president at Teleportec and one of its founders. "He's life-size, he's making eye contact, and there's no latency between when his mouth moves and you hear the words."
