Sensor fusion

This application provides a dynamic visualization of your device's 3D orientation through an interactive 3D compass. By leveraging the power of various sensors and advanced sensor-fusion techniques, it offers an engaging way to see how your device's movements translate into real-time 3D space.

The app harnesses data from the gyroscope, accelerometer, and compass, combining them in unique ways to display a 3D compass that responds to your device's rotations. This not only showcases the potential of sensor technology but also enhances the user experience with a novel approach to understanding device orientation.

One of the standout features of this application is the introduction of two innovative virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors integrate the Android Rotation Vector with a virtual gyroscope, resulting in an unprecedented level of stability and precision in pose estimation. This fusion technique sets a new standard for accuracy and reliability in orientation tracking.

In addition to these advanced sensors, the application offers a variety of other sensors for users to explore and compare:

• Improved Orientation Sensor 1: A sensor fusion of the Android Rotation Vector and a calibrated gyroscope, offering less stability but greater accuracy.
• Improved Orientation Sensor 2: Another sensor fusion of the Android Rotation Vector and a calibrated gyroscope, providing more stability but slightly less accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to combine data from the accelerometer, gyroscope, and compass.
• Calibrated Gyroscope: Represents a separate result of Kalman filter fusion from the accelerometer, gyroscope, and compass.
• Gravity + Compass: A simpler approach to orientation using gravity and compass data.
• Accelerometer + Compass: Combines data from the accelerometer and compass for orientation tracking.
• 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 of the application is available to the public. You can find the link in the About section of the app.
