Abstract
Disclosed embodiments include a display system comprising an eye-box from which virtual images formed by the display system are visible. In some embodiments, the display system includes an image projector arranged to project a virtual image at a virtual image distance from the eye-box, and a user-tracking system arranged to determine an eye-box position of a user within the eye-box and a confidence value associated with the determined eye-box position. In some embodiments, the image projector is arranged to (i) project the virtual image at a finite virtual image distance after determining that the confidence value is above a threshold value and (ii) project the virtual image at an infinite virtual image distance after determining that the confidence value is below the threshold value.
