Abstract
A mixed-reality system for augmenting spatial sensor device readings comprises a first magnetic sensor device configured to transmit a magnetic field signal at a reduced rate relative to a previous transmission rate. The system also comprises a second magnetic sensor device configured to determine a measurement of the magnetic field signal. The measurement indicates a pose estimation of the first magnetic sensor device. Additionally, the system comprises a third spatial input device configured to acquire pose data of the first spatial input device through means other than the magnetic field signal. Further, the system comprises one or more processors configured to compute a pose of the first magnetic sensor device by at least augmenting the measurement of the magnetic field signal with the pose data acquired by the other spatial input device.
