No, she can't do it for books because there are no Raised Print books anymore.
As far as being tedious and reading one letter at a time, I think it's like learning to read in the first place; at first you have to sound out every letter, but soon you're clipping along and not doing that at all anymore. This is the way it is with braille too; at first you have to learn each letter, but after you're proficient a bit you use Contracted Braille, which is a sort of shorthand. A lot like the way people text - u instead of you, etc.
My grandmother is also quite hard of hearing too, so audio books are not a possibility for her. I just think that a refreshable display using the alphabet one already knows is much easier that trying to learn the entirely new braille alphabet at an advanced age. A person would still have to develop sensitivity in their fingertips, but they would have to do that with braille too.
Shrug.
I think it's worth a thought.
I'm sorry about your sight!
