Austin Seraphin, 36, is a Philadelphia-based accessibility consultant, a volunteer museum docent and a computer programmer. He has been blind since birth — but now he can “see” with a technique known as echolocation.
“By making a simple tongue click, I can actually see visual forms around me,” Seraphin says. “Seeing through sound, instead of seeing through light.”
Echolocation is not yet widely used in the blind community. There’s only one group, World Access for the Blind, that teaches the technique.
