I don't care to jump into this debate but I did happen to see a blind guy on my subway the other day... with his fingers on something that looked like something straight from Dr. Who.
After a few minutes I realized one hand on was using a chorded keyboard and the other was on the display, which appeared to be a dozen blocks of movable braille... I was fascinated by the whole setup, with the braille bumps moving up and down... watching him twitch his left hand and his right hand dance back and forth... then watching him smile... very quickly I realized, it was a notebook and he was reading a comedy...
Unfortunately, I couldn't ask him what he was doing exactly as he is Korean (and I live in Korea and my Korean sucks).
