that said, I have to admit that it doesn't really feel "right" based on what I've seen. there's so many limitations to the physical world that a virtual space doesn't have. i get that physical objects can participate in the UI and that arranging things in 3D space is sometimes nicer than using a mouse/keyboard.
However, the fact that there is still code written on pieces of paper, and that the projector can only show a 2D image (which is only primitively interactable) just looks super awkward. and the question of "what can you do" when you're staring at a blank table seems tough
again, it's super cool research but i wonder if he has plans to resolve some of these fundamental issues with mixing real and virtual
