Blind “Batman”

http://www.vk.tv/video/528037/blinde-batman-ziet-met-tongklikgeluid.html

This video follows a blind man in the Netherlands who navigates his environment by making clicking noises with his mouth.

In the video, Dan Kish talks about how his parents treated him no differently as a child, demanding him to act as a seeing child would. With these expectations Kish developed his own way of compensating for his lack of vision, using the feedback from a clicking noise of his tongue to identify objects around him.

(BTW, The video is mostly in English)
