Application Description

This application provides an innovative visualization of the 3D orientation of your device through a dynamic 3D compass. By leveraging the power of various sensors and advanced sensor-fusion techniques, it combines data from the Gyroscope, Accelerometer, and compass to create an interactive experience where rotating your device directly influences the 3D compass display.

A standout feature of this app is the introduction of two novel virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors merge the Android Rotation Vector with a virtual Gyroscope sensor, resulting in unprecedented stability and precision in pose estimation. This fusion sets a new standard for accuracy in device orientation tracking.

To provide a comprehensive understanding of sensor performance, the application includes several other sensors for comparison:

Improved Orientation Sensor 1: This sensor combines the Android Rotation Vector with a Calibrated Gyroscope. It offers higher accuracy but slightly less stability.
Improved Orientation Sensor 2: Also a fusion of the Android Rotation Vector and Calibrated Gyroscope, this sensor prioritizes stability over accuracy.
Android Rotation Vector: Utilizes a Kalman filter to merge data from the Accelerometer, Gyroscope, and Compass.
Calibrated Gyroscope: Represents the standalone result of Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
Gravity + Compass: A straightforward combination of these two sensors.
Accelerometer + Compass: Another basic sensor combination for orientation tracking.
Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
