This seems both promising and creepy.<p>Could make walking somewhere a lot easier for the blind. Could be a safety system that kicks in just before your kid chases a ball into traffic (if strong enough). Could help with training for sports (if precise enough).
Now combine it with transcutaneous electrical stimulation on the inner ear. In the past (2000s) there were more than a few studies show this could control walking direction of blindfolded participants too.
