I once saw a documentary on a haptic compass, built from some rumble packs. It allowed people to improve their way-finding skills, and if I recall correctly, people accustomed to the idea of having this extra sense after about a week or so.
I can’t easily find the original research (somewhere in the 1990s), but several hackers and artists have rebuilt or rediscovered the idea.
