I've had the good fortune to see people use the balance belt, a belt that you can wear if you have bilateral vistibular loss.
The tech is simple, but seeing someone go from not being able to walk without leaning against everything to walking as if nothing is wrong - within 30 minutes - felt like a miracle.
The haptic feedback is processed in a very old part of the brain, which makes learning to process and use it fast.
That looks like an interesting device, do you know if it available in the US? I had a friend lose some of his balance due to a tumor. He said he could do surprisingly well with his eyes, probably due to a lifetime of climbing, skiing, etc but others I know do not have that advantage.
This reminds me about reading on similar device which when worn provides haptic feedback indicating North. The intention is to give the wearer an instinctive sense of North which remains even after stopping to wear the device.
