Abstract
A method, system, device and computer readable medium for adaptively warning a driver includes detecting a behavior of the driver, the behavior including engagement in a secondary activity, which is an activity other than driving a vehicle. Based on the detected behavior, a level of engagement in the secondary activity is estimated, and, based on the estimated level of engagement in the secondary activity, the driver's level of perception of an external hazard is determined. A warning alert for the driver, when the level of perception is below a threshold is actuated. A reaction of the driver to the actuated warning alert is determined. Based on the reaction of the driver to the actuated warning alert, the warning alert is adjusted, and the warning alert is terminated when the level of perception becomes above the threshold because of the reaction of the driver to the actuated warning alert.
