Head tracker assembly

A method or orienting an IMU to an object, comprising:

• holding the IMU in physical alignment with the object;
• activating an input device to initiate the IMU to process the orientation of the IMU, the orientation of the IMU being that of the object to become a referenced orientation;
• coupling the IMU to the object in any orientation;
• and
• activating the input device a second time to initiate the IMU to capture the physical offset when coupled to the object;
• wherein the IMU applies the physical offset to subsequent frames of data reporting on the orientation of the object rather than the orientation of the IMU.

A method or orienting an IMU to an object, comprising:

• locating a secondary IMU in a remote electronic device;
• coupling the IMU to the object;
• locating the secondary IMU in the same orientation as the object;
• activating an input device to capture the orientation of the secondary IMU, this orientation becoming a reference orientation of the object;
• and
• capturing the orientation of the IMU upon activation of the input device to determine a physical offset between the orientations of the IMU and the object;
• wherein the IMU applies the physical offset to subsequent frames of data reporting on the orientation of the object rather than the orientation of the IMU.
