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 users an immersive experience of how their device moves and rotates in real-time.

The app integrates data from the Gyroscope, Accelerometer, and Compass, blending them in innovative ways to present a highly responsive 3D compass that moves as you rotate your device. This integration showcases the potential of sensor technology in mobile devices, allowing users to explore and understand the spatial dynamics of their device in a tangible and engaging format.

A standout feature of this application is the introduction of two new virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2". These sensors represent a significant advancement in sensor fusion technology, combining the Android Rotation Vector with a virtual Gyroscope sensor. This fusion results in a pose estimation that achieves unparalleled stability and precision, setting a new standard in mobile sensor technology.

In addition to these innovative sensors, the application offers a range of other sensors for users to compare and contrast:

• Improved Orientation Sensor 1: This sensor combines the Android Rotation Vector with a Calibrated Gyroscope, offering less stability but higher accuracy.
• Improved Orientation Sensor 2: This sensor also fuses the Android Rotation Vector with a Calibrated Gyroscope, but prioritizes stability over accuracy.
• Android Rotation Vector: Utilizes a Kalman filter to fuse data from the Accelerometer, Gyroscope, and Compass.
• Calibrated Gyroscope: Provides a separate result from the Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
• Gravity + Compass: A straightforward combination of these two sensors.
• Accelerometer + Compass: Another basic sensor fusion option.
• Deprecated Android Orientation Sensor: Uses a complementary filter to combine 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 to the source code in the About section of the app.
