Sure, there are braille tablets these days that are pretty amazing. They translate several words or lines of text from websites into raised braille dots on a physical surface that scrolls through the web, opening up the world to those who can’t view the content of computers and the internet through traditional screens. But there are challenges. According to Alex Russomanno of new Ann Arbor startup NewHaptics, current braille tablets are limited to small quantities of text at a time, they’re incredibly expensive to manufacture, and they don’t have any way to translate images or graphs. This leaves the blind locked out of visual content, maps and graphs on computers.
