Just recently I watched a documentary on Youtube (http://www.youtube.com/watch?v=G1QaCeosUmw) about a blind boy, now a parvenu (he has been on Opera and in various other shows and magazines), who uses echolocation to "see". Echolocation is the method dolphins and bats use to locate objects by sound, clicking and projecting sound waves forth, then interpreting the sound waves that bounce back as objects. The video shows him rollerskating, playing his gameboy, and dribbling and shooting a basketball. Not once in these actives was he maladroit. An outsider wouldn't believe Ben is blind as his movements and actions look like that of someone how has perfect vision. Not being a credulous person I doubted that this could be possible. However, the documentary goes on to tell how Ben has developed a sonar mind. It tells of submarine sonar operators who go through extensive training that teaches them how to use their sonar machines on the submarine to locate objects in the water. The sonar operaters must study the sounds to determine the size, shape and distance using machines that cost millions of dollars. Somehow, Ben has managed to train his brain to do the work of million dollar sonar machines. All throughout the documentary Ben remains sang-froid completely unperturbed by the fact that he is blind. Ben states he wants to live on his own and that being independent will not be hard. However, later in the documentary (Part 3) the narrator states that Ben may be quixotic, and must realize he has limits, despite his extrodinary skill. Ben parent's tried to send Ben to a school for the blind for year before he started highschool, however it quickly became an anathema for Ben, who functioned better than most of the other students. Later on, Ben recieved training from another blind person (Dan) who uses echolocation for mobility. However, Ben deprecated the thought of using a cane which Dan and Ben's mother both pushed him to do. Ben thought that he was not handicapped and that the cane would label him falsely. Dan's training showed Ben that even echolocation has limits and that later on a cane would be necessary. Ben, being only 14, was obdurate and showed choler whenever somehow suggested the use of a cane.
