New technology created by a team of Georgia Tech researchers could make controlling text or other mobile applications as simple as “1-2-3.”
Using acoustic chirps emitted from a ring and received by a wristband, like a smartwatch, the system is able to recognize 22 different micro finger gestures that could be programmed to various commands — including a T9 keyboard interface, a set of numbers, or application commands like playing or stopping music.
A video demonstration of the technology shows how, at a high rate of accuracy, the system can recognize hand poses using the 12 bones of the fingers and digits ‘1’ through ‘10’ in American Sign Language (ASL).
