Tap made a name for itself with its futuristic wearable keyboards, now it's introduced a new Minority Report-style feature guaranteed to make you feel like you're in a sci-fi movie. The Tap Strap 2's new AirMouse feature lets you control any Bluetooth-connected device with a simple, untethered wave of the hand. It comes with three modes of operation. First up is Mouse Mode, where you can control a cursor, click and scroll just like you would with a normal mouse (great for taking selfies). Then there's Multimedia Mode, where you can use airborne gestures to play and pause music, adjust volume and skip to the next or previous track.
