As many as two million people in the United States use American Sign Language, but not every user knows what every one of the thousands of signs mean. And there is no dictionary in which to look them up—sign dictionaries are organized by the written definition of the sign, not by the physical movement.
Now a team of researchers at Boston University is working on an interactive video project that would allow someone to trace an unfamiliar sign in front of a Web camera and have a computer program interpret and explain its meaning, according to the Associated Press.
The researchers, working with a three-year, $900,000 grant from the National Science Foundation, are trying to capture 3,000 ASL signs on video. Their goal is to develop a “backwards” dictionary that will allow people to look up any unfamiliar gesture.
If a deaf person signs to a someone who doesn’t understand the sign, that person could sit down in front of a computer, repeat the sign into a Web cam, and the program would identify possible translations by recognizing the sign’s visual properties. —Josh Fischman
