A method to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon a need for enhanced vision includes monitoring informational inputs describing an operational environment for the vehicle, processing the informational inputs to generate display requirements, generating the graphical images to be projected based upon the display requirements, and projecting the graphical images upon the transparent windscreen head up display. Processing of the informational inputs can include determining the need for enhanced vision based upon the informational inputs and generating the display requirements based upon the informational inputs and the need for enhanced vision.
