Claim 16:
17. A method comprising:
attaching a first target to an anatomy of a patient, the first target configured to provide positional information in up to six degrees of freedom to an optical sensor configured to provide optical information;
positioning a registration device to define at least one axis relative to an anatomy of the patient, the registration device attached to a second target in a known positional relationship, the second target configured to provide positional information in up to six degrees of freedom to the optical sensor;
using a sensor to provide to an intra-operative computing unit:
measurements for determining a direction of gravity; and
first optical information for the first target and the second target;

wherein the sensor comprises the optical sensor, and a measuring sensor configured to provide measurements for determining the direction of gravity; and
performing a registration with the intra-operative computing unit to register the anatomy of the patient in the intra-operative computing unit using the measurements for determining a direction of gravity and the first optical information.
