Logbar‘s sensor ring recognizes finger gestures and controls devices. “Ring” allows the wearer to write text messages by drawing in the air, make mobile payments, or control lights or a television. It is being tested for use with the Pebble watch, quadcopter drones and Google Glass.

It can be programmed to respond to original shape gesture commands, which could be useful for the disabled or visually impaired.

Wearers can receive vibrating alerts or view LED pinpoints near the button port, performing up to 1,000 gestures before its battery must be recharged.
