Meet the moky: a keyboard with a large invisible touchpad to help you get even more done on your mobile devices. It lets you type more conveniently on your device and also serves as a touch-enabled mouse. Whether you want to type & drag, drag & tap, or use multiple fingers to interact with your device, the moky has you covered.
It has a laser sensor to generate a large optical touch-pad. The keyboard pairs with your device via Bluetooth 4.0. The battery should last up to 3 months. The above video should give you a better idea how moky works. The project is currently active on Indiegogo.
