Quaternion-based fusion of gyroscopes and accelerometers to improve 3D angle measurement

Two methods to fuse a 3D gyroscope with a 3D accelerometer in order to measure rotations are presented. They are compared with a method requiring only a 3D gyroscope and assessed with a reference system. The good reported accuracies make this system suitable for clinical evaluation.
