Car-based detector reads facial expressions to identify irritation

And in the future, dashboard emotion detectors could search for signs of irritation in a bid to identify the first signs of road rage. A prototype of the device is able to read a driver's facial expressions using a tiny embedded camera. Scientists at École polytechnique fédérale de Lausanne (EPFL), Switzerland, developed the prototype device, which identifies a driver's emotions - including anger (pictured) - using an infrared camera placed behind the steering wheel to film their face Scientists at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, have developed the system which identifies which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise, or suspicion. They believe their technology could be of use in medicine, marketing, gaming and in driver safety. 'We know that in addition to fatigue, the emotional state of the driver is a risk factor, the researchers said.
