If you had no eyes to see with, how would you navigate your surroundings?
Daniel Kish had both eyes removed at the age of 13 months after being diagnosed with retinoblastoma, an aggressive form of cancer. He didn’t let that slow him down. Though blind he can mountain bike, navigate the wilderness alone and recognize a building as far away as 1,000 feet. Kish is president of a nonprofit organization called. World Access offers training on how to interact with one’s environment, using echolocation as a primary tool. Kish hears echos and interprets their meaning to visualize objects, similar to the way bats, beluga whales and dolphins ”see” objects…
He can hear the variation between a wall and a bush and a chain-link fence. Bounce a tennis ball off a wall, Kish says, then off a bush. Different response. So too with sound. Given a bit of time, he can echolocate something as small as a golf ball. Sometimes, in a parking garage, he can echolocate the exit faster than a sighted person can find it.
