Anindya Bhattacharyya has a story in the New York Times about his travels as a deaf-blind man in the U.S.:
WHEN you are deaf-blind, technology is an ever-present companion. I travel with a laptop for e-mail, phone and Internet access. I use a G.P.S.-equipped Braille Note note-taker to get information about my surroundings. To communicate with others, I have a Screen Braille Communicator with two sides: one in Braille, which I can read; the other an L.C.D. screen with a keyboard, for someone who is sighted.
