Mobile Control with Facial Gestures
From: ECN Magazine - 07/05/2017

Rostock researchers have evaluated various technologies with which the
movements of a person's head and face can be interpreted. In this process,
great importance was placed on practical use in everyday life. For example,
systems that read gestures using sensors directly on one's face are very
accurate and able to recognize a large number of gestures. They are so
conspicuous and unpleasant to wear, though, that they are not suitable for
daily use in public. Instead, systems are needed which are as inconspicuous
as possible, such as EarFS, a proprietary development of the Fraunhofer IGD.
This is a special ear plug that measures the muscular currents and
distortions of the ear canal which occur during facial movements. The sensor
detects even the smallest movements in the face through the way the shape of
the ear canal changes and measures muscle currents that arise during the
movement of the face or head.

The use of the technology is also imaginable in the medical field. For
example, it could help people with locked-in syndrome to communicate more
easily by allowing them to operate computers with facial movements.
