Abstract

A display system having an eye-box or viewing window from within which image content formed by thereby can be seen. The display system comprises an image projector and a user-tracking system such as an eye-tracking system. The image projector is arranged to project a virtual image at a virtual image distance from the eye-box. In some embodiments, the image projector is arranged to project a first virtual image at a first virtual image distance and project a second virtual image at a second virtual image distance different to the first virtual image distance. The user-tracking system is arranged to try and determine an eye-box position of a user within the eye-box. The user-tracking system is further arranged to determine a corresponding confidence value or level associated with the determination. The image projector is arranged to project the virtual image at a finite virtual image distance if the confidence value is above a threshold value. The image projector is further arranged to project the virtual image at an infinite virtual image distance if the confidence value is below the threshold value.
