Sensor fusion

This application provides a dynamic visualization of the device's 3D orientation through an interactive 3D compass. By harnessing the power of multiple sensors and advanced sensor fusion techniques, the app offers a unique experience that showcases the device's movement in real-time.

The app integrates data from the Gyroscope, Accelerometer, and Compass, combining them in various configurations to display the resulting 3D compass, which users can manipulate by simply rotating their device. This feature not only demonstrates the sensors' capabilities but also enhances the user's interaction with their device.

A significant innovation in this application is the introduction of virtual sensor fusion, specifically with the "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors blend the Android Rotation Vector with the virtual Gyroscope to deliver a pose estimation that boasts unmatched stability and precision. This advancement represents a leap forward in sensor technology application.

For users interested in exploring different sensor configurations, the app provides several options for comparison:

• 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, this time prioritizing stability over accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Provides a separate output from the Kalman filter fusion of Accelerometer, Gyroscope, and Compass data.
• Gravity + Compass: A simpler combination focused on basic orientation.
• Accelerometer + Compass: Another basic orientation configuration.
• Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
