Researchers at Osaka University in Japan have developed a human-machine interface that actually allows you to control something simply by grinding your molars together. The main idea is to help those who are unable to use their hands properly, where a hair band with infrared sensors will be able to detect motion muscles in your temple generates simply by pressing the rearmost teeth together. Errors are reduced as talking and eating movements result in totally different muscle movements instead. Hopefully, this technique will one day be expanded to controlling electric wheelchairs, as it currently only works great in turning a CD player on and off. I just won’t wear this when sleeping if I’m a tooth grinder, as I might wake up in a home where the TV is turned on, the vacuum has gone amok, and the blender has burnt itself out.
