Reading a computer screen in Braille is a cumbersome process today. The visually impaired people who rely on the system of raised dots only have access to one line at a time. Beyond that, current systems don't translate charts or graphs. A team of researchers from the University of Michigan are working on a solution. Their technology relies on pneumatic use of liquid or air to shrink the mechanism and expand it so it can display more at once. Their goal is for it to display the equivalent of a page of Kindle text at once.
