Sensor fusion

This application showcases the device's 3D orientation through an interactive 3D compass, offering a dynamic visualization of how the device moves in space. It leverages a suite of sensors and sensor-fusion techniques to provide users with a comprehensive understanding of the device's positioning.

By integrating data from the Gyroscope, Accelerometer, and Compass, the app presents this information in a 3D compass format that responds to the physical rotation of the device. This feature allows users to explore the real-time impact of their movements on the compass's orientation.

A standout feature of this application is its innovative use of virtual sensor fusion, introducing "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors merge the Android Rotation Vector with a virtual Gyroscope sensor, delivering an exceptionally stable and precise pose estimation that sets a new standard in mobile sensor technology.

For users interested in comparing different sensor outputs, the app offers a variety of options, including:

• Improved Orientation Sensor 1: A less stable but more accurate sensor fusion of the Android Rotation Vector and Calibrated Gyroscope.
• Improved Orientation Sensor 2: A more stable yet less accurate sensor fusion of the Android Rotation Vector and Calibrated Gyroscope.
• Android Rotation Vector: Utilizes a Kalman filter to fuse data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Represents the standalone result of Kalman filter fusion from the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: Combines gravity and compass data for orientation.
• Accelerometer + Compass: Merges accelerometer and compass data to determine position.
• Deprecated Android Orientation Sensor: Employs a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
