Technological devices for deaf-blind children: needs and potential impact.

The authors provide a glimpse into the world of congenitally deaf-blind children and how the application of technology might enable them to lead more productive lives. They describe this population and then summarize the present status of efforts to educate and communicate with them. A review of technological devices presently usable and potentially usable to complement these efforts is given. The authors conclude with a list of technological tools that are needed for communication with deaf-blind persons.
