Correct detection may not be possible when a device that includes an infrared light source ( such as a commercially available Driver Monitoring System ) is installed in the vehicle interior .
. The Driver Monitoring System may not operate correctly at the following times when the driver is wearing glasses or sunglasses . – The sunglasses do not allow the easy passage of infrared light . – The surrounding scenery is reflected strongly in the lenses of the glasses or sunglasses . – The eyes are hidden by the frame of the glasses and the user recognition camera cannot detect the eyes . – The light from an infrared light source ( LED ) is reflected in the lenses of the glasses or sunglasses . – The driver is wearing an eyepatch . – The driver is wearing a hat set deeply over the eyes . .
