> Supposedly AR glasses with multiple focal planes and with localized occlusion (blacking out the world; I recommend being more specific when referring to occlusion with respect to AR systems. There are two primary forms: (1) "Real Occlusion" in which selected wavefronts are blocked (occluded) such that a transparent near-eye display is capable of displaying black, (2) "Virtual Occlusion" in which real objects are actively scanned/tracked to permit virtual objects to appear occluded being real objects. ML system claims both capabilities, and I agree with you that Real Occlusion is several orders of magnitude more difficult. I think real occlusion is valuable, because in addition to displaying black it enables images to appear solid vice translucent. However, I don't feel it's an absolutely necessary feature for a quality AR systems. After all, ultra bright projection displays present perfectly fine images without displaying true black. They simply exploit the properties of human eye perception with respect to brightness contrast of adjacent pixels. An AR system can do the same. Personally, I would prefer to have a quality AR system with unlimited FOV constraints and virtual occlusion capability sooner rather than wait for real occlusion to be perfected.
