This application provides a dynamic visualization of the device's 3D orientation through an interactive 3D compass, showcasing the advanced capabilities of sensor technology and sensor-fusion techniques. By integrating data from the Gyroscope, Accelerometer, and Compass, the app displays a 3D compass that dynamically updates as the device is rotated, offering users an immersive experience of orientation tracking.

The standout feature of this application is the innovative 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 an exceptionally stable and precise pose estimation, setting a new standard in orientation tracking.

For those interested in exploring different sensor configurations, the application offers a variety of sensors for comparison:

• Improved Orientation Sensor 1: This sensor uses a fusion of the Android Rotation Vector and a Calibrated Gyroscope, providing less stability but higher accuracy.
• Improved Orientation Sensor 2: This sensor also fuses the Android Rotation Vector with a Calibrated Gyroscope but offers more stability at the cost of slightly reduced accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Represents a separate 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: Employs a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
