• the optical path of at least one eyepiece configured to direct the virtual GUI towards the corresponding eye;
• and
• at least one eyepiece is associated with an eye-tracker configured to track movement of the corresponding eye relative to the virtual GUI to yield a tracked eye, the eye tracker further comprising abeam-splitter configured to:
• receive the image and direct the image along the optical path towards the corresponding eye;
• and
• receive light reflected from the corresponding eye and direct the light towards a sensor of the eye-tracker;
• and
