Claim 13:
14. A method for foveated display of augmentation imagery, the method comprising:
receiving, using an eye tracking system, a position of a pupil of a user;
generating, using the eye tracking system, 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;
estimating, using a head tracking system, a change in orientation of the user's head at a head tracking rate;
generating, using the head tracking system, jitter data at a jitter sensing rate, wherein the jitter data represents the change in orientation of the user's head;
generating, using a light generator, a color encoded light associated with the augmentation imagery, wherein the light generator comprises a 2D pixelated display and an optical system;
receiving, using a controller in communication with the light generator, the head tracking system and the eye tracking system, render data, the eye tracking data, and the jitter data, wherein the render data comprises content and location information relating to the augmentation imagery;
generating, using the controller, 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;
generating, using the controller, a color mapping with a plurality of resolutions, as a function of the render data and the eye tracking data;
estimating, using the controller, 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;
stabilizing, using the controller, 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;
projecting, using the 2D pixelated display, the color encoded light incident to an optical system at a refresh rate equal to or greater than the projector update rate; and
imaging, using the optical system, the color encoded light into the field of view of the user.
