Abstract:
1. An apparatus, comprising: an image source to generate display light; light bending optics to deliver the display light from the image source to a near-to-eye emission surface for emitting the display light to an eye of a user within an eyebox; an eye tracking camera system for acquiring an image of the eye for tracking movement of the eye; an eyebox actuator for adjusting a lateral position of the eyebox; and a controller coupled to the eye tracking camera system to receive image data and to determine a location of the eye based on the image data, the controller coupled to the eyebox actuator to control the eyebox actuator to dynamically adjust the lateral position of the eyebox to follow the movement of the eye in real-time such that the eyebox moves laterally when the eye looks left or right to dynamically extend an effective size of the eyebox from which the eye can view the display light, wherein the light bending optics comprise:
