Students invent Bluetooth gloves that turn sign language into speech

Two University of Washington undergraduates have won a $10,000 Lemelson-MIT Student Prize for gloves that can translate sign language into text or speech.

The Lemelson-MIT Student Prize is a nationwide search for the most inventive undergraduate and graduate students. This year, UW sophomores Navid Azodi and Thomas Pryor — who are studying business administration and aeronautics and astronautics engineering, respectively — won the Use It undergraduate category that recognises technology-based inventions to improve consumer devices.

Their invention, SignAloud, is a pair of gloves that can recognise hand gestures that correspond to words and phrases in American Sign Language. Each glove contains sensors that record hand position and movement and send data wirelessly via Bluetooth to a central computer. The computer looks at the gesture data through various sequential statistical regressions, similar to a neural network. If the data match a gesture, then the associated word or phrase is spoken through a speaker.

They honed their prototype in the UW CoMotion MakerSpace — a campus space that offers communal tools and equipment and opportunities for students to tinker, create and innovate. For Azodi and Pryor, that meant finding a way to translate American Sign Language into a verbal form instantaneously and in an ergonomic fashion.

“Many of the sign language translation devices already out there are not practical for everyday use. Some use video input, while others have sensors that cover the user’s entire arm or body,” said Pryor, an undergraduate researcher in the Composite Structures Laboratory in the Department of Aeronautics & Astronautics and software lead for the Husky Robotics Team.

“Our gloves are lightweight, compact and worn on the hands, but ergonomic enough to use as an everyday accessory, similar to hearing aids or contact lenses,” said Pryor.

The duo met in the dorms during their freshman year and discovered they both had a passion for invention and problem solving. Azodi has technical experience as a systems intern at NASA, a technology lead for UW Information Technology and a campus representative for Apple. His long history of volunteer work — which includes organizing dozens of blood drives and working with Seattle Union Gospel Mission, Northwest Harvest and Ethiopia Reads — gave motivation to build a device that would have real-world impact.

“Our purpose for developing these gloves was to provide an easy-to-use bridge between native speakers of American Sign Language and the rest of the world,” Azodi said. “The idea initially came out of our shared interest in invention and problem solving. But coupling it with our belief that communication is a fundamental human right, we set out to make it more accessible to a larger audience.”
