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.
