Between voice commands, motion tracking, and brainwaves, there are many ways the future can go when it comes to controlling our next-generation of mobile devices. A new wearable called NailO could be one of those options.

Created by a group of MIT researchers, it’s a wireless mobile controller that looks nothing more than a decorative nail sticker at first glance. Under the sticker’s colorful facade, though, sits an ensemble of tiny electronic components that allow it to pair with devices over Bluetooth to serve as a miniature trackpad.
