Sensor fusion

This application provides a dynamic 3D visualization of device orientation, functioning as an advanced 3D compass. It leverages the power of multiple sensors and sophisticated sensor fusion techniques to deliver an immersive user experience. By integrating data from the Gyroscope, Accelerometer, and Compass, the app offers a real-time 3D compass that users can interact with simply by rotating their device.

A key feature of this application is its innovative approach to sensor fusion, introducing two virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors combine the Android Rotation Vector with a virtual Gyroscope sensor, resulting in a pose estimation that boasts exceptional stability and precision, setting a new standard in sensor technology.

In addition to these novel sensors, the application includes a range of other sensors for users to compare and analyze:

• Improved Orientation Sensor 1: This sensor integrates the Android Rotation Vector with a Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: This variant fuses the Android Rotation Vector with a Calibrated Gyroscope, providing more stability at the cost of reduced accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Represents the isolated result of a Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A combination of gravity and compass data.
• Accelerometer + Compass: Merges data from the accelerometer and compass.
• Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.

For those interested in the technical aspects, the source code is openly accessible, and the link to it can be found in the About section of the app.
