An impressive Kickstarter project out of Japan was launched recently called Ring. No, it doesn't involve a haunted videotape. This smart ring detects movement with enough fidelity to recognize gestures drawn in the air by an index finger and transmit them to your iPhone. Using the iOS app, users can program those gestures to execute commands, such as translating into text, launching apps, or approving transactions. A small sensor on the inside has to be touched in order to initiate a command, plus there's a vibration motor and LEDs in there to let you know about incoming notifications from your iPhone. There's going to be a Ring store which highlights apps that make use of Ring's API, and they've already tested it with a few popular accessories, like Philips Hue, AR Drone, Google Glass, and WeMo.
