Teaching LaTeX to visually disabled

I will teach a blind person how to use LaTeX this week. Has anyone any hints for me or package recommendations?

Not sure whether this includes output considerations. If so, see LaTeX to Braille. –  Werner Mar 7 '12 at 5:32
Here some comments on the course. There were three students, two of them seeing. The blind student used a netbook with a Braille display and audio output attached. As editor he used TeXniccenter and got along quite well with it. –  Uwe Ziegenhagen Mar 11 '12 at 7:12
