Crazy Ear plugs


You may soon be able to accept a call on your mobile device with just smile or wink, thanks to scientists who have developed an earplug that can detect facial gestures to control smartphones.

Modern mobile devices are usually controlled by means of a touch screen. In everyday life, however, there are many situations in which this type of operation cannot be implemented.

Scientists at the Fraunhofer Institute for Computer Graphics Research IGD in Rostock in Germany have developed EarFieldSensing (EarFS), that recognises facial gestures via a special ear plug.
