The Kiss Controller interface has two components: a customized headset that functions as a sensor receiver and a magnet that provides sensor input. The user affixes a magnet to his/ her tongue with Fixodent. Magnetic field sensors are attached to the end of the headset and positioned in front of the mouth. As the user moves her tongue, this creates varying magnetic fields that are used to control games.
Now, if only her controller had voice operation as well.
