Yesterday I read an article in the paper about a legally blind man who is a so called "wizard" as a hitting coach for baseball.  The man said that he is able to see his pupils swing out of the corner of his eye.  And out of the corner of his eye he said he is able to just see a triangle between the hitters chin, the end of the bat, and the players elbow/torso.  He then said he is able to fill in the rest of the image and he even went on to say he is able to see what will happen next in the swing. 

This got me thinking about the conversation on edges and how we fill in the pictures.  One of the interesting things in the article was that there were many people who believed his hitting instruction was nonsense because he was blind.  On the other hand he was contracted by pro-baseball teams, sent 30+ players to D1 schools, and coaches many youngsters.  It seems that a man who has been legally blind for 35 years is able to create the correct image in his brain more times than not.  This may be from the fact that putting images together in the brain is not only a function of seeing, but the man may use his other senses to piece together the swing.  Maybe since his eyesight is week, the inputs from his other senses are stronger?
