From ExtremeTech:
Infinite Z's zSpace technology combines stereoscopic images with infrared cameras that actually track head and hand movements to construct a more realistic holographic effect.
?
This allows you to move your head so that you can view a hovering object from different perspectives. The screen actually changes what is being displayed based on where youre looking at it.

This innovation allows the illusion of three dimensions to work much more effectively. When you add the ability to manipulate objects in 3D space with its special stylus, this stops being a gimmick. This actually has real-world uses now.

For zSpace llusion to work, you need to wear a pair of special glasses. Not only do the glasses perform the required image separation for stereoscopy, but they also have embedded infrared reflectors to help the system track your head.
