Tablets. Wave of the future. Heck, wave of NOW, right? Well, what if you're blind? How's that flat, keyboard-less screen going to help you? Researchers at Stanford have come up with a way that blind people can navigate these mobile devices. The BBC quotes one of the researchers, Sohan Dharmaraja, "Instead of having fingers that find the buttons, we built buttons that find the fingers." The idea is that you place your fingers on the screen and the keyboard adapts to their position. No timeframe for when an app like this will be available to the public, but Dharmaraja is hopeful.
