Aria: Gesture Control for Smartwatches & Phones

Meet the Aria: a smart device that adds gesture control to your Pebble or Android Wear smartwatch, allowing you to get things done with simple finger gestures. It will be available as a clip or smartstrap for Android Wear and Pebble watches respectively. It connects to Android Wear devices via Bluetooth, allowing you to control music and other features on your smartphone.

As you can see in the above video, you can use such a solution to communicate with your GoPro camera with simple finger gestures. The project is getting funded on Kickstarter.
