Sensor fusion

This application visualises the 3D orientation of the device as a 3D com.

This application demonstrates the capabilities of various sensors and sensor-fusions. Data from the Gyroscope, Accelerometer and com are combined in different ways and the result is shown as a 3D com that can be rotated by rotating the device.

The major novelty in this application is the fusion of virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2" fuse the Android Rotation Vector with the virtual Gyroscope sensor to achieve a pose estimation with a previously unknown stability and precision.

Apart from these two sensors, the following sensors are available for comparison:

- Improved Orientation Sensor 1 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - less stable but more accurate)

- Improved Orientation Sensor 2 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - more stable but less accurate)

- Android Rotation Vector (Kalman filter fusion of Accelerometer + Gyroscope + Com)

- Calibrated Gyroscope (Separate result of Kalman filter fusion of Accelerometer + Gyroscope + Com)

- Gravity + Com

- Accelerometer + Com

- Deprecated Android Orientation Sensor (Complementary filter fusion of Accelerometer + Gyroscope + Com)
