Smartwatches such as the Moto 360 are powerful already. You can enhance their capability with a smart solution such as Aria. It is a gestural controller for wearable devices that lets you use your finger gestures to control your watch. It has sensors to detect finger tapping, flicking, and other movements.
Aria fits on any wrist and has a flexible design. You won’t even feel you are wearing it. At the same time, the device lets you control your smartwatch without having to touch it. The above video shows the Aria add-on in action. You will be able to find it on Kickstarter soon.
