I quickly narrowed down on VR experiences that provide a decent feeling of facsimile to real life being the most interesting and engaging. Beat Saber is a case in point here but for me it was combat flight sims using stick, throttle and pedals. Moving to gestures and eye tracking wrecks all of that.
I also don’t know why the original article calls using a mouse indirect as if we aren’t masters at that as well. As well as a spatially aware species we are also a tooling using species. We are experts at leveraging our spatial reasoning to manipulate tools in the world to do things we otherwise couldn’t. A mouse movement in the world translating to moving a cursor on screen is a perfect fit.
You have those when moving a mouse while holding a button, but that's not related to UI, you could just as well use it to do nothing, feedback is the same - NOT from the UI
Otherwise your fingers have the same things, so any gesture involving those is feedback just like the one you get if you touch non-finger object like a mouse
All of this is exactly the same - you have no tactile UI feedback
I suspect that we are going to see most apps centre around this finger/thumb motion.
