Not OP, but another visual aphant. Navigation - I'm doing the same thing, but without "seeing" it. I know Georgetown is N-NE of Austin, Liberty Hill is due W from Georgetown, IH-35 runs N-S but actually slightly NE-SW through Austin for example. I can draw pretty good maps on command (if not to scale), but I don't "see" that until I put it on paper. I think I actually have a much better recall of spatial relations than my wife, who has a vivid mind's eye. Regarding math: again a similar process, but I don't "see"the equations. Coding is interesting because when I'm really in the zone I feel like I can sit, think, and come up with a holistic design for some problem. Then as I start to write the code I can "feel" the congruence or discongruence between the code I've written and the design I conceptualized. But it's not, for example, a visualized graph in my head. It's more of a physical graph, like holding a carved statue and feeling the curves, edges, and features. Except it's not the same physical sensation as touch, but a mental analog. Edit: another commentator called it "imaginary proprioception" which I find very apt.
