providing a user wearable viewscreen and camera system configured to be carried by a single user including:
(i) a first viewscreen configured to be positioned near a first eye of the single user;
(ii) a second viewscreen configured to be positioned near a second eye of the single user;
(iii) at least a first camera configured to have a first field of view or a second camera configured to have a second field of view relative to the first viewscreen and the second viewscreen from the user wearable single viewscreen and camera system when worn by the single user; and
(iv) a user wearable viewscreen and camera system tracking device fixed to the user wearable viewscreen and camera system configured to allow the user wearable viewscreen and camera system to be tracked and registered relative to the subject;

placing an instrument tracking device fixed to an instrument in the first field of view of the first camera or the second field of view of the second camera;
fixing a subject marker to the subject at a first location having an identifiable shape to be viewable by at least the first camera or the second camera;
operating a processor system to execute instructions (i) to determine a relative position of the instrument tracking device relative to the subject marker fixed to the subject based on a first signal from the first camera or a second signal from the second camera regarding a view of the instrument tracking device relative to the subject marker and (ii) generate an instrument icon to be displayed in at least one of the first viewscreen or the second viewscreen to be viewed by at least one of the first eye or the second eye; and
displaying a supplemental viewing area within the first or second field of view, where the single user can selectively select or choose information to be displayed in the supplemental viewing area including displaying real time images, pre-acquired images, and other information in the supplemental view area;
wherein the instrument representation is represented as the instrument icon and an anatomy representation is represented as an anatomy icon;
wherein the instrument icon and the anatomy icon each have a selected opacity to view both the instrument icon and the anatomy icon substantially simultaneously such that the instrument icon can be viewed within the anatomy icon substantially simultaneously;
wherein the first viewscreen or the second viewscreen are substantially transparent and configured to allow the user to view the subject, through the first or second viewscreens;
wherein the processor system is further configured to generate the instrument icon and the anatomy icon and display the instrument icon and anatomy icon at a position spaced away from the subject on at least one of the first view screen or the second view screen to allow the single user to have a substantially unobstructed view of the subject while viewing the instrument icon and the anatomy icon.
