A situation awareness method can be used to provide information to a vehicle operator via first, second, and third substantially transparent ambient displays that are coupled to a windshield of a vehicle. The situation awareness method includes the following steps: (a) monitoring a physiological state of the vehicle operator; (b) monitoring a vehicle operating parameter of the vehicle; (c) monitoring a vehicle context data; (d) identifying a predetermined physiological condition based on the monitored physiological state of the vehicle operator; (e) identifying a predetermined vehicle operating condition based on the monitored vehicle operating parameter; (f) identifying a predetermined vehicle context condition based on the monitored vehicle context data; (g) adjusting a luminance of the first, second, and third substantially transparent ambient displays based on the identified predetermined physiological condition, the identified predetermined vehicle operating condition; and the identified predetermined vehicle context condition, respectively.
