Think of the classic scene from Star Wars in which the robot R2-D2 projects the shimmering holographic image of Princess Leia onto the floor of Luke Skywalker's garage. It is as if she is in the room with him, though only 6 inches tall.
Now imagine you are Luke Skywalker — and Princess Leia is projected life-size, full color, and high-resolution. She sits across the table, interacting with you eye-to-eye. More movie magic? Nope. This is the future of videoconferencing.
