Development of driver's emotional recognition system

The driver's feelings can affect the safety of traffic. As a result, cars will soon be equipped with driver identification and rating systems to enhance road safety.

The system has exactly identified the face of the driver

Scientists at the Swiss Federal Polytechnic University Lausanne (EPFL) and PSA Peugeot Citroen (France) have jointly developed a driver's identity model based on facial expressions . The device consists of a small infrared camera (to capture the face of the subject) and is mounted behind the steering wheel to avoid distracting the driver.

This system can identify many different types of emotions such as anger, fear, joy, grief, horror, surprise or suspicion. "We know that in addition to fatigue, the driver's emotional state is a risk factor. For example, when angry, drivers become aggressive and less focused , "the scientists explained.

Currently, this system can accurately identify the driver's anger in most cases and the next goal is to make it possible to detect real-time emotion with a more advanced algorithm. Experts are also testing a fatigue and sleep deprivation tester based on the driver's level of closeness to develop an alarm system that prevents drivers from falling asleep while driving. In addition, they also researched the driver's mental states using a voice recognition system and lip motions.
