I think what hes asking for is something that would only take place when you are blind. If your blinded on an ocean you still might hear water slosh against your boat when you go south. But when you hit land you might feel the grass on your feet. Something like this would be especially helpful if your summoned after being blinded. It would be nice to know when you passed from the ocean onto land, or from the forest onto a road to get your bearings. Flight would likely negate this, and wearing footwear would make it much less likely to go off. It would also be helpful for newer players who dont know the exact steps between places, without making blind suck.

Just some examples, and all of this is assuming I even understood fleshofchaos' suggestion.
