Inertial Measurement Units (IMUs) provide data on linear and angular motion, by using a combination of accelerometers and gyroscopes and sometimes also magnetometers. Qualisys provides integration with IMUs from several leading vendors and the means to get effortless synchronization between motion capture data and IMU data, through the QTM software. Qualisys can currently integrate with IMUs from XSens, Delsys, Cometa/Myon, and Noraxon.
