This application provides a dynamic visualization of the device's 3D orientation through an interactive 3D compass interface. By leveraging a variety of sensors and sophisticated sensor-fusion techniques, it showcases how data from the Gyroscope, Accelerometer, and compass can be merged to enhance the user's experience. Users can manipulate the 3D compass simply by rotating their device, offering an engaging and intuitive way to understand spatial orientation.

A standout feature of this application is the integration of virtual sensors, specifically "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors combine the Android Rotation Vector with a virtual Gyroscope sensor, resulting in a highly stable and precise pose estimation that sets a new benchmark in mobile device orientation tracking.

In addition to these innovative sensors, the application includes several other sensor options for users to explore and compare:

• Improved Orientation Sensor 1: This sensor fuses the Android Rotation Vector with a Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: Utilizing the same fusion technique, this sensor prioritizes stability over accuracy.
• Android Rotation Vector: This utilizes a Kalman filter to integrate data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: The output of a separate Kalman filter fusion involving the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A combination that provides orientation data based on gravity and magnetic field readings.
• Accelerometer + Compass: Another method to determine orientation using these two sensors.
• Deprecated Android Orientation Sensor: An older sensor using a complementary filter to combine data from the Accelerometer, Gyroscope, and Compass.
