A team of Swiss researchers has developed an in-car camera to detect angry or upset drivers, as the latest weapon to be used against driver-distraction.
The camera is mounted to the steering wheel, and has so far been programed to recognise ‘anger’ and ‘disgust’.
The team from the Swiss Federal Institute Of Technology said that early results were promising, with successful tests in both an office environment and a vehicle supplied by PSA Peugeot Citroen.
As to how the research team plans to use the data to improve road safety is unclear, but adjusting reaction times for autonomous safety features such as emergency city braking could be one advantage.
The camera will soon be programed to recognise fatigued drivers as well, able to monitor the driver’s eyelids throughout the journey.
The technology is still in its infancy, with the research team admitting that human emotions displayed through facial expressions can vary greatly.
