For almost 200 years, the Braille system has turned the written word into raised bumps that blind people can read. But what about images? A device called an embosser pricks and crimps 3D dots and lines on paper to produce a tactile image, allowing people to perceive pictures through touch. Chancey Fleet is a technologist at the Andrew Heiskell Braille and Talking Book Library in New York City. She’s Blind and teaches low-vision and blind patrons to print their own images.
