Holographic video that is more like Princess Leia’s is not yet possible.

Whereas the image of her appeared to be visible from all sides, Fattal’s technology makes it possible to see the hologram within a 60° arc, and even that requires 64 cameras positioned precisely. At Mobile World Congress, Fattal plans to demonstrate real-time video chat, which will require a bulky camera array. He imagines that eventually this setup could be streamlined by a dedicated device, such as a set of cameras arranged in the back of a TV set that would record images of a person looking at the screen and send them over the Internet to another screen where they would make up a hologram. “That’s something that’s completely doable in the not-so-distant future,” he says.
