Face up to your road rage – on camera

A NEW system could stop you from going over the top into full-blown road rage.
A prototype has been developed which could warn you before you lose your temper behind the wheel.
Researchers working in tandem with Peugeot/Citroen used in-car cameras to analyse facial expressions and detect emotion.
They say early tests give hope it could be helpful in alerting drivers before they berate some other road user – or worse.
The infrared camera on the dashboard tracked drivers' face movements and compared them with 'normal' expressions on its database. The experts managed to build recognition of anger and disgust into the system.
Now the researchers at EPFL's Signal Processing 5 Laboratory (LTS5) are working at improving where the camera is positioned, without affecting the driver's line of vision, and updating the software to make the process more sensitive to what the facial movements indicate.
But even at this early stage the system has been able to detect irritation in 80pc of cases.
