Abstract
A wearable magnetic sensor system includes a wearable article that spatially arranges magnetic sensor components around a user's torso to obtain magnetic sensor data used for body pose tracking. The wearable magnetic sensor system includes magnetic sensor components that sense a magnetic field generated by a magnetic transmitter. One or more wearable articles spatially arrange the magnetic sensor components at different locations on a body of the user, such as the arms and torso. The one or more wearable articles include a transmitter attachment mechanism for affixing the magnetic transmitter at, e.g., a torso of the user, and receiver attachment mechanisms for affixing the magnetic sensor components at, e.g., locations of the body other than the torso. The magnetic sensor components are spatially arranged at different locations on the user's body so as to maximize tracking accuracy and minimize interference between the magnetic sensors and the transmitter.
