The notes for a demo I gave to the LondonWeb meetup on 17th October 2013.

During the demo I showed attendees Dragon Naturally Speaking and NVDA screen reader. I also did quick demos of Voiceover (screen reader for iPhone and iPad) and Talkback (the Android equivalent).

I have some of the useful keyboard and gesture commands used with each of the screen readers.
