Data description
The backpack sensor data are saved in a row-column format. Each row represents one time step, and each of the 13 columns corresponds to a different variable. The data are logged to the file at 100 Hz. The following table provides an overview of the sensor data structure, and the physical units are given in brackets.
The calibration status for each of the three sensor types (accelerometer, rate gyro and magnetometer) is given on a scale from 0 (no calibration) to 3 (perfect calibration).
