Patent ID: 8616974

Claim:
A video game controller system comprising: a passive controller including a first magnetic sensor having a first plurality of sensor coils for sensing a magnetic field to generate first magnetic sensor data; and an active controller in a physically separate housing from the passive controller, the active controller including: a second magnetic sensor having a second plurality of sensor coils for sensing the magnetic field to generate second magnetic sensor data; a wired receiver operative to receive the first magnetic sensor data from the passive controller; a processing unit operative to phase correct the first magnetic sensor data and calculate a position and orientation of the passive controller using the phase corrected first magnetic sensor data; the processing unit further operative to phase correct the second magnetic sensor data and calculate a position and orientation of the active controller using the phase corrected second magnetic sensor data; and a wireless transmitter operative to transmit to a video game system the calculated position and orientation of the active controller and the calculated position and orientation of the passive controller.
