How very interesting - I would find north to be unhelpful as it's not intrinsically relevant to me. compared to say - which direction my house is from here.
Can you use sun or shadow based heuristics? (the sun rises in the east and sets in the west - give or take a correction factor for how far towards the poles you are). And maybe note the direction of a few star signs for night-time. cloudy-time is a bit harder to manage.
There are probably compass devices you can probably get as a bracelet. as an example http://www.ebay.com.au/itm/NEW-Tactical-WRIST-COMPASS-Military-Outdoor-Survival-Watch-Strap-Band-Bracelet-/121644526398?hash=item1c52942b3e Try camping stores also for similar devices? There is probably a watch with a built in compass.
To my knowledge there are no internal-magnet systems that impart a north-knowledge by having them inside your body.
I have a natural sense of direction (I assume nearly everyone does) can you train yours?
Question: I have a strong sense of a "dominant" direction (often, but not always, west). This direction is self-apparent in virtually every memory or mental visualization of any location I can think of. So, for example, captain's chair on the USS enterprise "obviously" faces "east", and the library on Myst island is obviously on the north side. I'm not going to forget which direction is down, and I'm not going to forget which direction is (usually) west.
Does anyone else here have oriented spacial memories?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
