Claim:
1. A method for verifying registration of an anatomy tracker, comprising the steps of: attaching a mechanical interface to an anatomy of a patient; establishing an expected correspondence between a checkpoint of the interface and the anatomy tracker; contacting the interface with a surgical tool of the surgical device, wherein a position of a portion of the surgical tool corresponds to a position of the checkpoint of the interface; receiving, by a computer, information indicative of the contacting of the interface with the surgical tool of the surgical device; determining, by the computer, the position of the portion of the surgical tool when the surgical tool is contacting the interface; determining, by the computer, whether the position of the portion of the surgical tool has the expected correspondence to the anatomy tracker; and using at least the determination of whether the position of the portion of the surgical tool has the expected correspondence to the anatomy tracker to determine whether the anatomy tracker has moved relative to the anatomy of the patient since an earlier registration of the anatomy; wherein the interface is disposed on a bone of the patient.
