I don't know much about it, but I was browsing Apple accessories the other day, and in the accessibility section, there is this amazing device[1]. As I understand it, somehow it takes the text on screen and raises tiny dots to make braille that can be re-written very quickly. I assume blind people knew about this, but I was stunned at how difficult I assumed it was to control the hundreds of dots on even a small display. Similarly, MOOCs with good captions plus these kinds of devices probably works at least as well as being in a classroom.
