1. A system to guide surgery comprising:
a first sensor unit comprising an optical sensor, the first sensor unit configured to be coupled to an object in a known or measurable orientation such that a relative position of the first sensor unit with respect to the object is known when attached, the optical sensor configured to receive light and determine a direction of the light;
a second sensor unit configured to be coupled to a first bone of a patient, the second sensor unit comprising markers configured to emit and/or reflect light to provide a signal representing a six degrees of freedom position to the first sensor unit and, in response to the signal, the first sensor unit generating and communicating sensor information with which to determine a relative position in six degrees of freedom of the object with respect to the first bone;
at least one human interface sensor to receive user input for an operation of the system;
a processor; and a non-transitory computer readable storage device storing instructions, which when executed by the processor, cause the system to:
perform operations to guide the surgery wherein at least some operations are responsive to the user input received and wherein the operations comprise displaying information in accordance with the relative position in six degrees of freedom of the object and the first bone as determined according to the sensor information and the relative position of the first sensor and the object.
