The system can include a controller, a waveform generator, and an electrical driver. The waveform generator can produce calibration waveforms under control of the controller. The system can also include conductive loops which are energized with electrical currents corresponding to the calibration waveforms. The controller can cause the waveform generator to generate a first calibration waveform to calibrate a first type of magnetic sensor in the display device, and to generate a second calibration waveform to calibrate a second type of magnetic sensor in the display device. The system may also include one or more optical fiducial markers in a known spatial relationship with respect to the conductive loops. The optical fiducial markers can be used to calibrate the alignment direction of one or more optical sensors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration of magnetic and optical sensors in a virtual reality or augmented reality display system","description":"A system for calibrating alignment of magnetic and optical sensors in a virtual reality (VR) or augmented reality (AR) device.
