Claim 13:
14. A method comprising:
using a human interface sensor of an optical sensor unit comprising an optical sensor to invoke a processor to perform a registration of a bone sensor unit to a bone from bone references indicated by a stylus coupled to a stylus sensor unit, wherein: the bone sensor unit is coupled to the bone for determining a first position, the first position associated with the bone, and the bone sensor unit comprises at least one first light reflector configured to provide to the optical sensor unit a reflected light used to determine the first position in six degrees of freedom; the optical sensor is configured to detect light within a field of view, the field of view for aligning with a site of a procedure; the optical sensor unit is configured to generate and communicate sensor information derived from the light received by the optical sensor; and the stylus sensor unit is coupled to the stylus for determining a second position, the second position associated with the stylus and the stylus sensor unit comprises at least one second light reflector to provide to the optical sensor unit a reflected light used to determine the second position in six degrees of freedom;
using the optical sensor unit to generate and communicate to the processor first sensor information derived from the reflected light from each of the bone sensor unit and the stylus sensor unit, the stylus sensor unit indicating the bone references and the first sensor information for determining a relative position of the bone and the stylus to perform the registration;
using the optical sensor unit to generate and communicate to the processor second sensor information derived from reflected light from each of the bone sensor unit and a tool sensor unit to receive display information associated with a relative position of the bone and a surgical tool, wherein: the tool sensor unit is coupled to the surgical tool for determining a third position, the third position associated with the surgical tool, and the tool sensor unit comprises at least one third light reflector configured to provide to the optical sensor unit a reflected light used to determine the third position in six degrees of freedom; and the processor is configured to: determine the relative position of the bone and the surgical tool using the registration and the second sensor information, determine the display information, and provide the display information to a display unit; and
receiving the display information via the display unit.
