Sensor fusion

This application provides a dynamic visualization of your device's 3D orientation through an innovative 3D compass interface. It showcases the power of sensor technology and sensor-fusion techniques by integrating data from the Gyroscope, Accelerometer, and compass. By simply rotating your device, you can interact with the 3D compass and see how different sensor combinations affect the orientation display.

One of the standout features of this application is its use of virtual sensor fusion, introducing "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors combine the Android Rotation Vector with a virtual Gyroscope to deliver unparalleled stability and precision in pose estimation.

For a comprehensive comparison, the application includes the following sensors:

• Improved Orientation Sensor 1: A fusion of the Android Rotation Vector and Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: Another fusion of the Android Rotation Vector and Calibrated Gyroscope, providing more stability but less accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Represents the separate output from the Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A straightforward combination of gravity and compass data.
• Accelerometer + Compass: Merges data from the Accelerometer and Compass.
• Deprecated Android Orientation Sensor: Uses a complementary filter to integrate data from the Accelerometer, Gyroscope, and Compass.
