Abstract
Magnetic sensor synchronization techniques for pose tracking in artificial reality systems include managing and sending, by one or more primary magnetic sensors, a wireless synchronization signal to other magnetic sensors to trigger sensing sampling. The primary magnetic sensor may generate and send sensor data to a wireless data hub that operates as a sensor data collector and transmits data for pose tracking in the system. Each of the other (non-primary) magnetic sensors, in response to receiving the wireless synchronization signal, updates its sampling starting clock based on new synchronization timing. Each of the magnetic sensors sends generated sensor data to its corresponding primary sensor or wireless data hub according to a different schedule to avoid conflicts between the various magnetic sensors. The synchronization process may be repeated a number of times if a sensor fails to receive or respond to a synchronization signal.
