This application provides an immersive experience by visualizing the 3D orientation of your device as a dynamic 3D compass. It showcases the power of sensor technology and sensor-fusion techniques, utilizing data from the Gyroscope, Accelerometer, and compass to create a responsive 3D compass that you can interact with by simply rotating your device.

One of the standout features of this app is its innovative use of virtual sensor fusion. It introduces "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2," which combine the Android Rotation Vector with a virtual Gyroscope sensor. This results in a pose estimation that offers unprecedented stability and precision.

For those interested in comparing different sensor technologies, the app includes the following options:

• Improved Orientation Sensor 1: A fusion of the Android Rotation Vector and a Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: Another fusion of the Android Rotation Vector and a 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: Represents the individual output of the Kalman filter fusion from the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A straightforward combination of these two sensors.
• Accelerometer + Compass: Another basic sensor fusion approach.
• Deprecated Android Orientation Sensor: Uses a complementary filter to blend 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.
