ABSTRACT
I remember watching a blind student several years ago walking across the campus of a large state university. He guided himself with a cane, tapping it against the sidewalk which ran in spokes from building to building. Although he knew the campus well, on that particular occasion he became distracted for a moment and wandered onto the grass, where he immediately lost all sense of direction. His movements became disorganized as he searched hopelessly for a bit of cement. He became visibly panicked until a passing student came up and led him back to the appropriate path. Once again he was able to continue toward his class unaided.
