It'd just be a blurry image, or flickery. Or worse, a rainbow mess. A 180Hz DLP is projecting the same 60fps footage 3x to eliminate rainbow effects.
If there's any tech that's giving MS an advantage, it'd exist in the projector market itself also.
If there's any tech that's giving MS an advantage, it'd exist in the projector market itself also. Note there
are cheaper laser projectors out there - that revolution happened, with projectors in mobiles and camcorders. They just aren't high res or bright yet. If they were, they'd have replaced lamp-based projectors.
Possibly, although the existence of the video doesn't really show that. MS have a patent. This is PR. Maybe they can drum up interest from 3rd parties for niche activities, rather than create a real home product? Even if they have a tech they want to introduce (which MS have always had with their RnD concept home - many, many techs that haven't yet made it to the mainstream), it would only be as an expensive extra like Sony's HVD. Maybe they can release it for £400 as a peripheral, but it's not going to be a standard component of Durango. It's way too costly and clearly niche.
Here's a
concept vid from Sony showing Move's use in projection mapping tracked to a camera. It's somewhat different to MS's 3D scanning, but the same sort of idea with no special effects applied, released publicly. It's not a commercial project - just a proof of concept for PR. Like patents, the existence of a video doesn't mean the intention to create or release a product idea, and certainly it says nothing about the affordability of such a product.
