1. A method of alerting a vehicle'"'"'s driver, comprising:

  • with a processor;

    measuring head movements of the driver by a wearable mount placed on the driver;

    calculating an azimuth value indicating a horizontal orientation facing direction of a head of said driver;

    receiving a vehicle bearing value indicating a current vehicle moving direction of a vehicle driven by the driver;

    calculating an angular difference between the azimuth value and the vehicle bearing value;

    receiving a first set of image data, the first set of image data captured by a first image capture module coupled to the wearable mount and directing outwardly from the driver to capture a driver'"'"'s perspective;

    receiving a second set of image data, the second set of image data captured by a second image capture module mounted on the vehicle and oriented toward the current vehicle moving direction to capture a vehicle'"'"'s perspective;

    processing the first and second sets of image data to determine a comparison result, the comparison result determined according to image similarity between the first and second sets of image data;

    generating an alert according to said comparison result and when the angular difference deviates from an angular threshold, said angular threshold selected from a plurality of predefined angular thresholds according to a traffic condition; and

    automatically presenting the alert via an alert module to the driver.
