This Is How Blind People Play Tennis

"Most blind kids just don't get early experience interacting with flying projectiles," says Daniel Kish, president of World Access for the Blind, an organization that teaches echolocation and mobility skills worldwide. Which is why it's hard to imagine children who are blind or even partly blind playing a game of tennis. However, an adapted version of the sport that uses a foam ball with suspended ball bearings so players can hear the trajectory of the ball, is just beginning to catch on in the United States, perhaps changing the way we see (or hear) the game of tennis.
