The Compass internally utilizes the accelerometer and magnetometer to estimate the device orientation in relation to the magnetic north. As the compass is vulnera-ble to external influences, it is recommended to disable the Compass in the pres-ence of strong magnetic fields.
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.
