I would definitely love such a device!
But I predict that this summer we will at most see a working prototype in a very well-controlled environment with pre-set projections custom-built for some hand-picked objects in that environment.
I’m not questioning if they can model the room. After all, the system uses geometric patterns projected on the environment + a camera to create a digital 3D model of the environment. All of that is ‘old tech’.
The way I see it, the real challenge will be customising the actual projections to be meaningful in the perceived environment. After all, not everybody has a map of the city pasted to the wall for the device to project an itinerary on. Or even if you have a map, will the device recognise it as such? And recognise the city? Most lkely not.
So unless you also buy some standardised props for these cool projections to work on, remind yourself that you’ll most likely be limited to some default pattern-projections on a vase or table. Maybe a picture and/or a text on a blank spot of a wall.
Related to that: what resolution would this thing have? Even a 4K projection smeared out over a room will have reasonably big pixels… Maybe too big to actually use for text?
