Stream IMU Data

Neon +1.1.2

Data generated by the IMU can be received using the receive_imu_data method. It returns a UTC timestamp in seconds, the head pose as a quaternion, gyro data, and accelerometer data as follows.

IMUData(
    gyro_data=Data3D(x=-0.1659393310546875, y=-0.1964569091796875, z=0.1735687255859375),
    accel_data=Data3D(x=-0.02880859375, y=-0.224609375, z=1.0068359375),
    quaternion=Quaternion(x=-0.06114135682582855, y=-0.090116947889328, z=0.8700147271156311, w=0.48084819316864014),
    timestamp_unix_seconds=1744297102.1941311
)
