Claim 4:
5. A method comprising:
obtaining a first output of a spatial orientation sensor when the spatial orientation sensor is at a first orientation;
rotating the spatial orientation sensor from the first orientation to a second orientation;
obtaining a second output of the spatial orientation sensor when the spatial orientation sensor is at the second orientation;
obtaining a third output of the spatial orientation sensor when the spatial orientation sensor is at a third orientation;
rotating the spatial orientation sensor from the third orientation to a fourth orientation;
obtaining a fourth output of the spatial orientation sensor when the spatial orientation sensor is at the fourth orientation;
determining a first rotation of the spatial orientation sensor from the first orientation to the second orientation based on the first output and the second output;
determining a second rotation of the spatial orientation sensor from the third orientation to the fourth orientation based on the third output and the fourth output;
determining a relative orientation of the spatial orientation sensor with respect to a reference frame based on the first rotation and the second rotation;
wherein at least three of the first orientation, the second orientation, the third orientation, and the fourth orientation are different from one another; wherein the first orientation and the second orientation are different; wherein the third orientation and the fourth orientation are different.
