In Germany the specialists of the University of Rostock have created a unique device, namely the headphones. Thanks to them, the phone calls can be answered by a smile. It is reported Politekspert.
Researchers have noticed that people are not always convenient to answer the call hands, even if it requires only one touch. To do this, they decided to find a new way to answer the call. They analyzed all the technologies that are now widely used on the market and found that there is still one that would recognize the facial expressions of the person.
So there is a new invention. Special headphones are able to recognize the smile of the owner or other facial gesture, after which it is automatically answering an incoming call. However, the researchers excluded from the list of gestures of hand movements, vibration while walking and some other movements that might confuse the device.
