This application provides a dynamic visualization of the device's 3D orientation through a 3D compass interface, showcasing the advanced capabilities of multiple sensors and their fusion techniques. By integrating data from the Gyroscope, Accelerometer, and compass, the app allows users to interact with a rotatable 3D compass by simply moving their device.
A standout feature of this application is the introduction of two novel virtual sensor fusions: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors combine the Android Rotation Vector with a virtual Gyroscope to deliver an unprecedented level of stability and precision in pose estimation.
For a comprehensive comparison, the app also includes the following sensors:
- Improved Orientation Sensor 1: A fusion of the Android Rotation Vector and a Calibrated Gyroscope, offering less stability but higher accuracy.
- Improved Orientation Sensor 2: Another 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 fuse data from the Accelerometer, Gyroscope, and Compass.
- Calibrated Gyroscope: Represents the separate result of a Kalman filter fusion of the Accelerometer, Gyroscope, and Compass.
- Gravity + Compass: Combines these two sensors for orientation data.
- Accelerometer + Compass: Merges these sensors to provide orientation feedback.
- Deprecated Android Orientation Sensor: Uses a complementary filter to fuse the Accelerometer, Gyroscope, and Compass.
