Given the brain plasticity those earlier experiments showed possible, I wonder how well someone would adapt to these after long term wearing?

FWIW, I tried this as a student, and in a couple of hours was biking campus paths. Decades ago, but my very fuzzy recollection is the key adaptation was sort of ignoring the oddity and going with familiar behaviors. So reaching to grab an object would "just work", unless I "thought about it" - then the hand would feedback the wrong way, followed by a "stop thinking!" and recovery after the bobble, or by a freeze and trying again. IIRC, it had a similar feel to doing things while viewing myself in a mirror. Meh - I set it aside after a day or so. But YMMV - different brains deal with the world very differently. I can run on spatial/kinesthetic with only spotchecks from vision, so perhaps this was merely tweaking that role. Might be interesting to try learning an unfamiliar physical task while inverted, and watch transfer in the other direction.
