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.
