Separate active and passive controllers each detect a generated magnetic field. The active controller phase corrects the detected magnetic field information transmitted from the passive controller and uses that to calculate the position and orientation of the passive controller. The active controller also phase corrects its own detected magnetic field information and uses that to calculate its position and orientation. The active controller transmits each of these calculated positions and orientations to a video game system directly or indirectly through the source of the generated magnetic field. The video game system is thus informed of the position and orientation of each of the active and passive controllers. Alternatively, the active controller creates a signal matrix using the phase corrected information and the position and orientation of a controller is calculated by either the source of the generated magnetic field or the video game system using the signal matrix.
