For Spatial Computing I had a lot of thoughts how interactivity should work in a 3d context. I'm building out development for it with Vive. Here's a working document of some user stories I'm working on to create this. Not positive on what's actually MVP, and what's not. Have been interested in arranging all this stuff in a perceptual hierarchy of needs (don't make me sick being more fundamental than being able to touch things)... maybe that reorganization of these ideas is next.
