QUEST FOR THE HOLY BRAILLE

摘要

Digital tablets provide access to a world of information-but there's no elegant, affordable way for the visually impaired to read from them. That's because current braille readers, which attach to the bottom of a tablet, provide room for only one line of text at a time. Researchers at the University of Michigan, led by Brent Gillespie, Alex Russo-manno, Mark Burns, and Sile O'Modhrain, hope to develop a refreshable display to translate an entire page at once. The project was partially motivated by O'Modhrain, who is visually impaired. "Existing displays don't allow you to access lots of braille code and graphical information," she says. "Math and music codes, for example, are displayed spatially, so that they're spread over multiple lines."
