Sensor fusion

This application provides a dynamic visualization of the device's 3D orientation through an interactive 3D compass. It leverages the capabilities of multiple sensors and advanced sensor-fusion techniques to offer a comprehensive demonstration of how these components work together to enhance user experience.

By integrating data from the Gyroscope, Accelerometer, and Compass, the app showcases the device's orientation in a 3D model that can be manipulated by physically rotating the device itself. This feature not only makes the app engaging but also serves as an educational tool for understanding sensor technology.

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 combine the Android Rotation Vector with the virtual Gyroscope to deliver a pose estimation that boasts unprecedented stability and precision.

For users interested in a detailed comparison, the app includes the following sensor options:

• Improved Orientation Sensor 1: A sensor fusion of the Android Rotation Vector and Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: A sensor fusion of the Android Rotation Vector and Calibrated Gyroscope, providing more stability but with slightly reduced accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to fuse data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Presents 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 readings.
• Deprecated Android Orientation Sensor: Employs a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.

The source code for this application is openly accessible, and interested users can find the link in the About section of the app.
