This application provides a dynamic visualization of the device's 3D orientation through an interactive 3D compass. By leveraging the capabilities of multiple sensors and advanced sensor-fusion techniques, it offers users a comprehensive understanding of how different sensor data can be combined to enhance orientation tracking.
The app integrates data from the Gyroscope, Accelerometer, and Compass, presenting the results in a 3D compass that users can manipulate by physically rotating their device. This hands-on approach allows for a tangible experience of how sensor data translates into real-world orientation.
A standout feature of this application is its innovative use of virtual sensor fusion. It introduces two new virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2." These sensors combine the Android Rotation Vector with a virtual Gyroscope to deliver pose estimation with unprecedented stability and precision.
For those interested in comparing different sensor technologies, the app includes the following options:
- Improved Orientation Sensor 1: A sensor fusion of the Android Rotation Vector and Calibrated Gyroscope, offering less stability but higher accuracy.
- Improved Orientation Sensor 2: Another sensor fusion of the Android Rotation Vector and 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 gravity and compass data for orientation.
- Accelerometer + Compass: Merges accelerometer and compass data.
- Deprecated Android Orientation Sensor: Uses a complementary filter to fuse data from the Accelerometer, Gyroscope, and Compass.
