Designers Bhargav Bhat, Hemant Sikaria, and Priya Narasimhan have designed HandTalk, a phone for the hearing impaired. The prototype glove uses the same gestures as does sign language, then translates them into audio, and plays back on a cell phone or other mobile device. Shown recently at the Carnegie Mellon University Center Expo, the HandTalk can only detect 32 words at this point, but its creators plan on expanding its vocabulary and integrating sensors and accelerometers to work with its flexor strips.
