Abstract
A system responds to detection of a vehicle situation by comparing a sensed eye gaze direction of the vehicle operator with data stored in memory. The stored data defines a first predetermined vehicle operator eye gaze direction indicating a high probability of operator desire that an alert signal be given and a second predetermined vehicle operator eye gaze direction indicating a low probability of operator desire that an alert signal be given. On the basis of the comparison, a first or second alert action is selected and an alert apparatus controlled accordingly. For example, the alternative alert actions may include (1) generating an alert signal versus not generating the alert signal, (2) generating an alert signal in a first manner versus generating an alert signal in a second manner, or (3) selecting a first value versus selecting a second value for a parameter in a mathematical control algorithm to determine when or whether to generate an alert signal.
