Could emotion detectors make driving safer?

Researchers in EPFL’s Signal Processing 5 Laboratory (LTS5), working with PSA Peugeot Citroën, have developed an emotion detector based on the analysis of facial expressions in a car, using an infrared camera placed behind the steering wheel. The researchers say they can read facial expressions and identify which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise, or suspicion. The problem was to get the device to recognize irritation on the face of a driver. Everyone expresses this state somewhat differently — a kick, an epithet, a nervous tic or an impassive face. To simplify the task at this stage of the project, Hua Gao and Anil Yüce, who led the research, chose to track only two expressions: anger and disgust. How to detect irritation The system “learned” to identify the two emotions using a series of photos of subjects expressing them. Then the same exercise was carried out using videos. When the test failed, it was usually because this state is very variable from individual to individual — given the diversity of how we express anger.
