This idea may not be vastly useful, but it has occured to me that when learning any form of new language or input system for anything there is no substitute for practice.
My idea is to make gloves that allow typing to be performed using standard sign language symbols for the letters,- i say letters
as some of the words use big actions or ones that may be ambiguous for computer use. this system would be useful for anyone who wants to/needs to learn sign language.

||This is an active topic of research. Some systems use cameras, some use gloves.
||I linked before to a virtual keyboard that could pick up gestures as well as typing. I don't know if it would be discriminating enough to pick up sign language, but I'll see if I can find the link again.
