Researchers at the University of Chicago have unveiled an alternative user interface called LipIO that receives and transmits digital information via small lip and tongue movements. This is obviously a boon to those with certain disabilities who may not have the use of their eyes or hands.LipIO features a thin and flexible plastic sheet packed with conductive materials. The sheet is affixed to the skin along with electrodes that provide contact with the lip. The device works via electrostimulation, with the top layer receiving inputs from the tongue or lower lip via capacitive touch. The trio of researchers created the device using off-the-shelf hobbyist-grade components and have open-sourced all of their work.While the lip system is perfect for people with disabilities, the inventors see plenty of alternative uses. Various demonstrations show LipIO being used to tune a guitar, receive navigation information while cycling and provide DJs with an additional control source for adding effects.A. Jingu et al.The
