Claim 0:
1. A system for foveated display of augmentation imagery, the system comprising:
an eye tracking system configured to:
receive a position of a pupil of a user; and
generate eye tracking data, at an eye tracking rate, in response to the position of the pupil of the user, wherein the eye tracking data comprises a gaze vector;

a head tracking system configured to:
estimate a change in orientation of the user's head at a head tracking rate; and
generate jitter data at a jitter sensing rate, wherein the jitter data represents the change in orientation of the user's head;

a light generator configured to generate, a color encoded light associated with the augmentation imagery, the light generator comprising a 2D pixelated display and an optical system;
a controller in communication with the light generator, the head tracking system, and the eye tracking system, the controller configured to:
receive render data, the eye tracking data, and the jitter data, wherein the render data comprises content and location information relating to the augmentation imagery;
generate a field mapping, at a projector update rate no greater than the eye tracking rate, the head tracking rate, and the jitter sensing rate, in response to the render data, wherein the field mapping comprises a color mapping;
generate a color mapping with a plurality of resolutions, as a function of the render data and the eye tracking data;
estimate an image displacement with respect to the augmentation imagery as a function of the change in orientation of the user's head, at an augmentation stabilization rate that is equal to or greater than the projector update rate; and
stabilize, in response to the jitter data, a position of the color encoded light within a field of view of the user, wherein the position of the color encoded light within the field of view of the user is stabilized at the augmentation stabilization rate; and

wherein:
the 2D pixelated display is configured to project the color encoded light incident to an optical system at a refresh rate equal to or greater than the projector update rate; and
the optical system is configured to image the color encoded light into the field of view of the user.
