DID YOU KNOW?
Did you know that it's possible for blind people to locate objects through echolocation? While others use a white cane, a guide dog, or apps for the blind like the Be My Eyes, others rely on echolocation to navigate. Ever wondered how the blind can ride bicycles on the road, even with bumper-to-bumper traffic? That's echolocation coming into play. How does it work, you might ask. Well, to put it simply, echolocation is the process of using sound waves to locate objects in the area. As a matter of fact, bats use this to find food in the dark. But blind and visually impaired people can also take a cue from these flying mammals. One example is Daniel Kish, an American expert of human echolocation who currently serves as the President of World Access for the Blind. Some has even given him the moniker of the real Batman.
Mr. Kish has been blind since he was an infant, but that has never been a reason to stop living his life on his own terms. True enough, he follows his bliss through hiking and mountain biking. Through human echolocation, he uses sound waves to create a blueprint of his environment on his brain. Now, how does he do it? Simple: by clicking his tongue. According to Mr. Kish, the process is very much similar to how bats use echolocation - you produce a sound and the sound waves bounce back from the physical surface. This means that when a person clicks their tongue and listens to the echoes, they are likely to get a mental picture of their surroundings. It gives them an idea of the object's distance, size, texture, and density. Impressive, right?
