Bizarre mouthpiece lets you fully control your smartphone or computer using your TONGUE

Have you ever remembered something for your shopping list while cooking or working out, and couldn't grab your phone to note it down? Soon you may be able to log your groceries using only your mouth, thanks to a smart retainer developed at the Massachusetts Institute of Technology (MIT). The device, MouthPad, connects to smartphones or computers via Bluetooth, and allows the user to select buttons by sweeping their tongue across a trackpad chip. They can left click by pressing it, and right click by making a'sip' gesture. The team from startup Augmental, a spinoff from MIT Media Lab, hope their invention will help those with impaired hand control to live more independently.
