1. A method for managing display of an icon in an eye tracking augmented reality device that concurrently enables a world view of an external environment of a viewer, the method comprising:
projecting 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;
estimating changes in orientation of the eye;
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, projecting the icon at the tracked position when the tracked position is within a projectable image space of the eye tracking augmented reality device; and
responsive to the repositioning criteria being met, repositioning the icon to the target position.
