Sensor fusion

This application serves as a dynamic 3D compass that visually represents the orientation of your device in three dimensions. By harnessing the power of multiple sensors and advanced sensor-fusion techniques, it offers an engaging way to explore how different data inputs can affect the displayed orientation.

The app integrates data from the Gyroscope, Accelerometer, and compass, fusing them in various configurations to present the result as an interactive 3D compass that responds to the device's rotation. This unique approach not only showcases the potential of sensor technology but also provides a practical tool for understanding device orientation.

A standout feature of this application is its innovative use of virtual sensor fusion. Specifically, the "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2" combine the Android Rotation Vector with a virtual Gyroscope sensor, resulting in pose estimation that boasts unprecedented stability and precision. These sensors offer users a choice between:

• Improved Orientation Sensor 1: A fusion of the Android Rotation Vector and a Calibrated Gyroscope, which is less stable but offers higher accuracy.
• Improved Orientation Sensor 2: Also a fusion of the Android Rotation Vector and a Calibrated Gyroscope, but this one prioritizes stability over accuracy.

For those interested in exploring different sensor combinations, the app also provides access to several other sensor options for comparison:

• Android Rotation Vector: Utilizes a Kalman filter to fuse data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: A separate output from the Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A simpler combination focusing on these two inputs.
• Accelerometer + Compass: Another straightforward fusion method.
• Deprecated Android Orientation Sensor: An older method using a complementary filter to combine the Accelerometer, Gyroscope, and Compass.
