Daniel Kish: How I use sonar to navigate the world

submitted by Zawash

9 years 7 months 3 weeks ago

YT: Daniel Kish has been blind since he was 13 months old, but has learned to "see" using a form of echolocation. He clicks his tongue and sends out flashes of sound that bounce off surfaces in the environment and return to him, helping him to construct an understanding of the space around him. In a rousing talk, Kish demonstrates how this works and asks us to let go of our fear of the "dark unknown."

I remember hearing about this guy last week on NPR, pretty amazing stuff. But I find the comparison to Batman to be a little off, Daredevil would be a better match.

True that.

Here's a short where he rides a mountain bike:

As I understand it, the visual cortex does for real start adopting this other sensory input as if it were coming from the eyes and put together a "fuzzy" representation of the world in your brain. Our brains take what they can get and work with it. Neuroplasticity FTW.
