In sixth-sense terms, I once heard of experiments with a belt which would vibrate to indicate magnetic north. Apparently people really missed it when they had to give it up.
Commercialized: > The original idea for North Paw comes from research done at University of Osnabrück in Germany. In this study, rather than an anklet, the researchers used a belt. They wore the belt non-stop for six weeks, and reported successive stages of integration.
Where I’ve lived my entire life I have a long river immediately due south of me that runs east to west parallel, years ago I internalise north as away from the river.
It’s really discomfiting when I’m away and lose track of that completely.
