Claim 18:
19. An eye tracking augmented reality device that manages display of an icon while concurrently enabling a world view of an external environment of a viewer, the eye tracking augmented reality device comprising:
a display to project the icon onto a retina of an eye such that the icon appears at a target position located at a predefined offset from a center of gaze outside a fovea;
an eye orientation tracking system to estimate changes in orientation of the eye;
a processing device, comprising:
a processor; and
a non-transitory computer-readable storage medium storing instructions that when executed by the processor cause the processor to perform steps comprising:
updating a tracked position of the icon based on the changes in orientation such that the icon appears to maintain a substantially stable appearance with respect to the world view;
detecting if repositioning criteria are met based on the tracked position;
if the repositioning criteria are not met, causing the display to project the icon at the tracked position when the tracked position is within a projectable image space of the display; and
responsive to the repositioning criteria being met, repositioning the icon to the target position.
