Sensor fusion

This application showcases the 3D orientation of your device through an interactive 3D compass, allowing you to explore the capabilities of various sensors and their fusions. By rotating your device, you can see real-time changes in the 3D compass, which is powered by a combination of data from the Gyroscope, Accelerometer, and compass.

The standout feature of this app is the innovative fusion of virtual sensors, specifically the "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors integrate the Android Rotation Vector with the virtual Gyroscope sensor to provide a pose estimation that boasts unmatched stability and precision.

For those interested in comparing different sensor technologies, the application offers several options:

• 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 slightly less accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Outputs the separate results of the Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: Combines these two sensors for orientation data.
• Accelerometer + Compass: Another straightforward sensor fusion option.
• Deprecated Android Orientation Sensor: Uses a complementary filter to merge data from the Accelerometer, Gyroscope, and Compass.

The source code for this application is openly available, and you can find the link in the About section of the app.
