Sensor fusion

This application offers an immersive visualization of your device's 3D orientation through a dynamic 3D compass. By leveraging the power of various sensors and advanced sensor-fusion techniques, the app combines data from the Gyroscope, Accelerometer, and Compass to provide a comprehensive view of your device's spatial positioning. Users can interact with the 3D compass by simply rotating their device, which updates the compass in real-time.

A standout feature of this application is the integration of virtual sensors, introducing "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors fuse the Android Rotation Vector with the virtual Gyroscope sensor, achieving unprecedented stability and precision in pose estimation. This innovative approach enhances the accuracy and reliability of the 3D compass visualization.

For users interested in exploring the capabilities of different sensor configurations, the application offers a range of sensors for comparison:

• Improved Orientation Sensor 1: This sensor combines the Android Rotation Vector with a Calibrated Gyroscope, offering higher accuracy but less stability.
• Improved Orientation Sensor 2: This sensor also merges the Android Rotation Vector with a Calibrated Gyroscope, prioritizing stability over accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to fuse data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Represents the separate output of a Kalman filter fusion involving the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A straightforward combination of these two sensors.
• Accelerometer + Compass: Another basic sensor fusion method.
• Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.

For those interested in the technical aspects of the application, the source code is publicly available. You can find the link to the source code in the About-section of the app.
