We stumbled across this awesome little device called Aria. Aria is a small add-on that attaches to smartwatch bands (Pebble, Android and soon Apple watch). Basically once it’s clipped on it gives you the ability to control your device through finger gestures.
Instead of using the touch screen or watch dial, you just move your hand/fingers. It connects to your smartwatch using Bluetooth. Hard to explain but check out the video below.
Aria are planning on starting a Kickstarter campaign (crowd funding). Stay tuned if you want to contribute.
