Abstract (en)
[origin: WO2017136833A1] An augmented reality display system includes an electromagnetic field emitter to emit a known magnetic field in a known coordinate system. The system also includes an electromagnetic sensor to measure a parameter related to a magnetic flux at the electromagnetic sensor resulting from the known magnetic field. The system further includes a depth sensor to measure a distance in the known coordinate system. Moreover, the system includes a controller to determine pose information of the electromagnetic sensor relative to the electromagnetic field emitter in the known coordinate system based at least in part on the parameter related to the magnetic flux measured by the electromagnetic sensor and the distance measured by the depth sensor. In addition, the system includes a display system to display virtual content to a user based at least in part on the pose information of the electromagnetic sensor relative to the electromagnetic field emitter.
