SMARTING PRO features an integrated 9D inertial motion unit for measuring gyroscope, accelerometer, and magnetometer data with high precision. The way they are combined allows very precise head motion tracking in all three directions.
It’s possible to record gyroscope and accelerometer data in X, Y and Z axes, as well as 4 quaternion channels.
Quaternion data is used for Head model motion in our software (see gif). Based on the movement of the SMARTING PRO amplifier, it’s possible to reproduce the movement of the head during the experiment. You can observe the movements in our software or record quaternions in a file and reconstruct the movements with your own head model.
