Claim 8:
9. A system for viewing a subject when performing an operation on the subject, comprising:
a user wearable viewscreen and camera system configured to be carried by a single user and held relative to a first eye of the single user, having a field of view, the user wearable viewscreen and camera system including:
a mounting structure;
a first viewscreen configured to be positioned near the first eye of the user and fixed to the mounting structure; and
a first camera configured to have a first field of view from the user wearable viewscreen and camera system when worn by the single user;

an instrument tracking device fixed to an instrument viewable by the first camera;
a subject marker fixed to the subject at a first location on the subject and having an identifiable shape viewable by the first camera;
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;
a processor system configured 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 regarding a view of the instrument tracking device relative to the subject marker and (ii) generate an instrument icon to be displayed in the first viewscreen to be viewed by the first eye; and
a supplemental viewing area displayed within the field of view of the user wearable viewscreen and camera system, 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 viewing 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 is substantially transparent and configured to allow the user to view the subject, through the viewscreen;
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 the first 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.
