PERIPHERAL SALIENT FEATURE ENHANCEMENT ON FULL-WINDSHIELD HEAD-UP DISPLAY
First Claim
1. Method to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon visual information present in a peripheral zone of vision, the method comprising:
- monitoring a location of visual information corresponding to critical information with respect to the windscreen;
processing the location of the visual information to generate display requirements describing the visual information as present in the peripheral zone of vision, the processing comprising;
monitoring an estimated operator gaze location with respect to the windscreen;
comparing the estimated operator gaze location to the location of visual information; and
generating the display requirements when the estimated operator gaze location is distant from the location of visual information by more than a threshold distance;
generating the graphical images to be projected based upon the display requirements; and
projecting the graphical images upon the transparent windscreen head up display based upon the estimated operator gaze location.

Abstract
A method to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon visual information present in a peripheral zone of vision includes monitoring a location of visual information corresponding to critical information with respect to the windscreen, processing the location of the visual information to generate display requirements describing the visual information as present in the peripheral zone of vision, generating the graphical images to be projected based upon the display requirements, and projecting the graphical images upon the transparent windscreen head up display based upon the estimated operator gaze location.

12. Method to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon prompting to a visible feature not directly visible through the windscreen, the method comprising:
-
monitoring a location of a visible feature corresponding to critical information; monitoring an estimated operator head location; determining whether the visible feature is directly visible through the windscreen based upon the monitored location of the visible feature and the estimated operator head location; and when the visible feature is not directly visible through the windscreen, projecting the graphical images upon the transparent windscreen head up display prompting to the visible feature. - View Dependent Claims (13, 14, 15)

16. System to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon visual information in a peripheral zone of vision, the system comprising:
-
the transparent windscreen head up display; an enhanced vision system system manager monitoring a location of visual information corresponding to critical information; monitoring an estimated operator gaze location with respect to the windscreen; determining the location of visual information to be in the peripheral zone of vision based upon comparing the location of the visual information and the estimated operator gaze location to a threshold distance; and generating display requirements prompting a view to the visual information when the location of visual information is in the peripheral zone of vision; a graphics system generating the graphical images to be displayed based upon the display requirements; and a graphics projection system communicating with the graphics system and displaying the graphical images upon the transparent windscreen head up display. - View Dependent Claims (17, 18, 19)
