== Characteristics ==
• * Provides orientation in world coordinate system. • * The error in orientation estimation is characterized by an offset between real and estimated device orientation. Typically an accuracy of 10-20° is achieved. In the presence of strong magnetic fields orientation estimation is unusable. • * Pose estimation suffers from noticeable jitter if Compass is used as the only orientation source. • * The orientation is updated with roughly 250Hz. • * Orientation estimation is not responsive and suffers from noticeable delays. • * Requires accelerometer and magnetometer.
