Refreshable braille displays translate information from computer screens into raised characters, often along the bottom of a keyboard. But this technology can cost thousands of dollars and is limited, typically displaying a string of characters much shorter than most sentences. Researchers now report an improved material that could take these displays to the next level, allowing those who are blind or who have low vision to more easily understand text and images, while lowering cost.
