Abstract
Apparatus and methods are described including tracking a tool portion and a patient marker from a first line of sight, using a first tracking device disposed upon a first head-mounted device that includes a display. The tool portion and the patient marker are tracked from a second line of sight, using a second tracking device. When a portion of the patient marker and the tool portion are both within the first line of sight, an augmented reality image is generated upon the first display based upon data received from the first tracking device and without using data from the second tracking device. When at least the patient marker portion and the tool portion are not both within the first line of sight, a virtual image of the tool and anatomy of the patient is generated using data received from the second tracking device. Other applications are also described.
