    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to “watch” TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

Now the new system changes TV signals to data a Braille line can use. “The key to the system is the possibility of using subtitles(字幕) to collect TV information, ” Garcia Crespo explains. “Subtitles travel with the image(影像) and the audio in electromagnetic waves we don’t see. But an electronic system can keep those waves. ”

First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

Now another app gets to work, which sends the data out to people’s Braille lines on demand. “This is done in real time, in less than a second, ” Garcia Crespo says. This lets a deaf-blind person “watch” TV as it’s broadcast. The system will work with various Braille lines, as long as there’s a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.
