(Back in college, I had a job scanning/OCRing texts for various students who needed text-to-speech versions of their reading material. There was one guy in the class after mine who was blind, who'd come in once in a while for exams I'd proctor. He had a laptop attached to this sort of panel of flat-headed pins that he'd lay his fingers on, and the pins would bounce up and down--in Braille, I assume?--to give him the text. It was one cool piece of tech.)
