I use echolocation especially outside.  If I know there is a building in
front of me, I can tap my cane on the ground and hear how close I am to it.
I know other blind people who do this as well, and I was once told by a
mobility instructor it was OK to do this.  This technique is especially
useful if you get disoriented and you know you're close to something that is
large and won't move.
