What is the difference between raw data and calibrated data?

Raw inertial data contains the 16 bit analog to digital converter readings of the MT's internal sensors. No calibration or other processing is applied before the data is sent from the motion tracker to the PC.

Calibrated data is unprocessed, that is, only the physical calibration model is applied to the values retrieved from the analog-to-digital converters. No additional filtering or temporal processing is applied to the data. The calibration comprises scaling and offset removal, misalignment correction, temperature compensation etc.

The orientation output is estimated by our XKF fusion algorithm.
