CNN profiles blind man who sees with ears
As part of the CNN Ideas series, CNN Tech profiles Daniel Kish, the founder of the nonprofit World Access for the Blind. In the article, Kish talks about teaching a technique called “human echolocation” — or seeing the world through sound — to blind people all over the world. Kish contends that blind students are taught to be dependent on sighted people, partly because 99% of them, he said, are taught by people who can see. Kish aims to ‘liberate’ students. Kish believes his blind students can become less dependent on sighted people by learning to click their tongues and listen for the resulting echoes from buildings, cars and other objects to navigate their surroundings.
