WEARABLE DEVICE IMU INTRINSIC CALIBRATION

Abstract: a method including during a calibration operation, establishing communication with a test fixture, via a communication channel between the test fixture and a head mounted device (hmd), during the calibration operation, obtaining inertial measurement unit (imu) data based on output from an imu in the hmd generated based on movement of the hmd caused by a text fixture to which the hmd is coupled, during the calibration operation, generating imu calibration data for the hmd based on the imu data, during the calibration operation, store the imu calibration data in the hmd, and after the calibration operation is completed (or in response to completing the calibration operation), implement at least one technical measure to prevent subsequent modification of the imu calibration data.
