Blind persons, when you get a new home do you fully map it out by touching every surface in it? (self.Blind)
submitted by sharp-string
When you move in to a new home there are rooms, doors, appliances, furniture, pipes, windows, stairs, closets and cupboards - do you map out every nook and cranny in detail to build a 3d model in your mind and how would you do it to build the model accurately and keep it accurate? For sighted people the 3d model would be re-confirmed every time their cone of vision came across those surfaces.
