In an effort to bridge the communication gap between American Sign Language (ASL) speakers and people with hearing, two undergraduates at the University of Washington developed gloves that translate sign into text or speech.
The SignAloud gloves, invented by Thomas Pryor and Navid Azodi, won the Lemelson-MIT competition. Sensors in the gloves record hand position and movement and send the data via Bluetooth to a central computer that analyzes the data through various sequential statistical regressions. When a match with a gesture is found the corresponding word or phrase is played through a speaker.
