picoRing signals

Caption

The different scroll directions and button push send signals of different frequencies for the wristband to interpret and pass to the device. The angle of the ring also affects the signal-to-noise ratio. Careful engineering of the signal coils optimizes for the most natural angle it takes on your finger.
