Application Description

This application provides a dynamic visualization of a device's 3D orientation through an interactive 3D compass. By harnessing the power of various sensors and advanced sensor-fusion techniques, it delivers an engaging user experience where rotating the device directly influences the 3D compass display.

A standout feature of this application is its innovative use of virtual sensor fusion. The "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2" blend the Android Rotation Vector with a virtual Gyroscope sensor, resulting in an unprecedented level of stability and precision in pose estimation.

Users can compare different sensor outputs to understand their performance variances:

Improved Orientation Sensor 1: Fuses the Android Rotation Vector with a Calibrated Gyroscope, offering less stability but higher accuracy.
Improved Orientation Sensor 2: Also fuses the Android Rotation Vector with a Calibrated Gyroscope, but prioritizes stability over accuracy.
Android Rotation Vector: Utilizes a Kalman filter to combine data from the Accelerometer, Gyroscope, and Compass.
Calibrated Gyroscope: Provides a separate result of Kalman filter fusion from the Accelerometer, Gyroscope, and Compass.
Gravity + Compass: Combines these two sensors for orientation data.
Accelerometer + Compass: Another sensor fusion approach.
Deprecated Android Orientation Sensor: Uses a complementary filter to merge data from the Accelerometer, Gyroscope, and Compass.
