OK I'll say it. It's describing the next gen. VR headset from Ready Player One.

I always enjoy reading about this kind of thing. I don't know what's the novel aspect of this patent though — the idea of using multiple overlapping projectors so that the display can be farther from the eye and still paint the full retina through the pupil? Something else?

  I imagine that it’s focal length. With current headsets you’re staring at a screen directly in front of your eyes, only giving the illusion of depth. This appears to be modulating the wavefront so that optically it’s similar to a scene that is actually x distance away from you. Your eyes can tell what distance you’re focusing at, so this should be significantly more immersive should anything come of it. In other words, with this device, objects would actually be in the distance, rather than being smaller on a nearby screen.

    It reminds of a video about research Nvidea was conducting on lenses that allowed to have a display closer than the 7 or so cm that was the limit in how close our eyes could focus on an object. In other words, this isn't just about being more immersive, it's about having headsets that are not these big blocks of plastic we put on our heads, but more like everyday glasses or at least goggles.

A hologram is by definition a wavefront reconstruction. This sounds a lot like the Hololens? The intellectual property game has gotten extremely confusing. The more I study it, the less firm it has become. At least this patent _application_ has some decent figures.

  I think it's doing what the hololens does (waveguide) but the hololens is not particularly near-eye. If you can put the display closer to you, you can have less bulky gear (assuming the focus-distance of a wave-guide was the issue...?)

Suggestion: tag these links with [patent] or something similar. Those who work in the industry in question may appreciate the heads-up, in order to avoid inadvertently gaining knowledge that could expose them to willful-infringement claims later.
