'FingerPing' Wearable Recognizes Small Hand Gestures to Control Smart Tech
Using acoustic sounds emitted from a ring and received by a wristband, this wearable system from Georgia Tech can recognize 22 different micro finger gestures that could be programmed to various commands - including application commands like playing or stopping music. "FingerPing" can recognize hand poses using the 12 bones of the fingers and digits %9D1%9D through %9D10%9D in American Sign Language.

Tech Briefs spoke to lead researcher Cheng Zhang about promising applications for the technology.
