KC (left) shows Roma (right) her BrailleNote. It's like a PDA with a braille display. It has capabilities for email, address book, word processing, alarms and schedules, and more.
Roma's device is a Screenbraille; it's used by deaf-blind people so they can communicate with sighted, hearing people who can't sign or fingerspell. The sighted person types, and their words are displayed in braille. The deaf-blind person types, and their words display in print.
