Claim 24:
25. A non-transitory computer readable storage device storing instructions, which when executed by a processor, cause the processor to perform steps comprising:
receiving input from at least one human interface sensor of an optical sensor unit for invoking the processor to perform a registration of a bone sensor unit to a bone, wherein: the optical sensor unit comprises an optical sensor configured to detect light within a field of view, the field of view for aligning with a site of a procedure; and the optical sensor unit is configured to generate and communicate sensor information derived from the light received by the optical sensor;
performing a registration to register a relative position of the bone sensor unit to the bone using first sensor information received from the optical sensor unit to perform the registration, the first sensor information indicating references for the bone, the first sensor information derived from reflected light from each of the bone sensor unit and a stylus sensor unit, and 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; and the stylus sensor unit is coupled to a stylus for identifying the references for the bone, 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 comprising at least one second light reflector to provide to the optical sensor unit a reflected light used to determine second position in six degrees of freedom;
determining a relative position of the bone and a surgical tool in six degrees of freedom in accordance with the registration and second sensor information, the second sensor information derived from reflected light of the bone sensor unit and a tool sensor unit, 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 to provide to the optical sensor unit a reflected light used to determine the third position in six degrees of freedom;
determining display information in accordance with the relative position of the bone and the surgical tool; and
providing the display information for presenting by a display unit.
