Up to four people can walk around a holographic image and interact with it wearing only a small set of glasses – a far cry from bulky AR headgear. It's set to go on sale in 2018.

The idea of the hologram table has been a staple of sci-fi for decades. Indeed, hologram tables themselves have popped up here and there, but never really caught on. That's mainly because in the past, they just haven't worked like people hoped.

The problem is this: a hologram is a computer-generated stereo image, much like the kind of image you see when you watch a 3-D movie. But if you've got a group of people standing around a table, looking at the same image, they'll all see the same perspective on it, and the image won't change as they move around. It breaks the illusion.
