The NFB blog tipped me to this story. B&N hasn't talked up any of this yet, but one of the apps in the Nook App Store was developed by Benetech, the nonprofit which maintains Bookshare (the world's largest online library or people with print disabilities). The app is called Go Read, and besides being able to read Daisy format digital talking books, this app will also allow you to access a hidden settings menu.
I'm pretty sure this menu is a holdover from the underlying Android, not one which was developed by B&N, because it does not have a label nor have I found another way to get to it other than through this app. Once in the menu, I can see options for "Talk Back", "Explore by Touch", and more.
I've been playing with it for about half an hour now, and while I wouldn't want to to be stuck with that voice it is not as annoying as I expected. There are also a couple quirks. For example, the unlock screen sometimes requires a 2-finger swipe while other times only a single fingered swipe. And the accessibility features have to be enabled by someone who can see the screen.
But even with the shortcomings, Barnes & Noble has still managed to surprise me.
Update: A reader has told me that the 8.9" Kindle Fire HD has similar accessibility settings. Curiously enough, I cannot find those features on my 7" KFHD.
