Echolocation helps a blind man “see” objects around him

Daniel Kish uses echolocation to better navigate space.

The man has been blind since childhood, but he moves calmly along the streets, avoiding any obstacles - from benches and poles to trees and cars. All thanks to clicking his tongue. The sound of the clicks bounces off objects and returns, helping Daniel's brain create something like a map.

Thanks to echolocation, he learned to determine not only the distance to an object, but also its shape, texture and even density. This is not a superpower, but a skill that the man has developed over the years, and now teaches it to others. Confidently, calmly, without ostentatious heroics. Just a man who refused to live within the framework and came up with an alternative to vision.
