Hmm—AR glasses + smart watch (or FitBit) + ring? 🧐
[A] finger could be used to write legibly in the air without a touch surface, as well as providing input taps, flick gestures, and potentially pinches that could control a screened device from afar. Thanks to the magnetic sensing implementation, researchers suggest that even a visually obscured finger could be used to send text messages, interact with device UIs, and play games. Moreover, AuraRing has been designed to work on multiple finger and hand sizes.
