Well that's not fair. The "occlusion mask" is referenced in a patent application, but basically is just a LCD that blocks out light that sits in front of your eye. re: fullscreen google glass, at best.
Well, that's exactly the point: an anti-display which lets through what parts of reality the system wants you to see, and blocks light from what it wants you to not see - so another display can render something to fill in the blocked-out areas. Rather than the "ghosting" of putting an elephant over your hand, with the light of both being added, the LCD acts as a dynamic precision cutout shutter, blocking the light from where the elephant would be and letting another display fill in _all_ the light you'd expect from that visual addition.
Does this mean that people looking at me using my magic leap will be able to see an outline of shapes which I'm projecting? That's going to be awkward.
