Sensor fusion

This application provides an innovative visualization of the device's 3D orientation through a dynamic 3D compass. By harnessing the power of various sensors and advanced sensor-fusion techniques, users can explore the capabilities of their devices in a new and interactive way.

The application combines data from the Gyroscope, Accelerometer, and Compass to create a 3D compass that responds to the physical rotation of the device. This real-time interaction allows users to experience the impact of their movements directly on the screen, offering a practical demonstration of sensor technology.

A key feature of this application is the integration of virtual sensors, specifically "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2". These sensors merge the Android Rotation Vector with a virtual Gyroscope sensor, resulting in a pose estimation that boasts exceptional stability and precision. This fusion represents a significant advancement in sensor technology, providing users with a more accurate and reliable experience.

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

• Improved Orientation Sensor 1: A sensor fusion of the Android Rotation Vector and Calibrated Gyroscope, known for its higher accuracy but slightly less stability.
• Improved Orientation Sensor 2: Another sensor fusion of the Android Rotation Vector and Calibrated Gyroscope, offering greater stability at the cost of some accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Provides a separate result from the Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: Combines gravity and compass data for orientation.
• Accelerometer + Compass: Merges accelerometer and compass data for orientation.
• Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
