1. A system for aiding in interaction with a physical object, the system comprising:
a display device defining a plane and being located on a first side of the physical object; and
a navigation system coupled to a control system and being configured to:
register computer images to the physical object;
track a pose of the physical object and the display device in a common coordinate system; and
control the display device to render the registered computer images according to the tracked pose of the physical object and the display device; and
wherein a perspective of the rendering is based on a virtual camera that has a virtual position located on a second side of the physical object opposite to the first side, and wherein the virtual camera has a field-of-view that faces the plane of display device, and wherein the virtual position of the virtual camera updates automatically in response to adjustment to the pose of the display device; and
wherein the virtual position of the virtual camera is located at a predetermined distance from the plane of display device and wherein the predetermined distance updates automatically.
