This application demonstrates the capabilities of various sensors and sensor-fusions. Data from the Gyroscope, Accelerometer and compass are combined in different ways and the result is shown as a cube that can be rotated by rotating the device.
Read the full documentation here.
The major novelty in this application is the fusion of virtual sensors: Improved Orientation Sensor 1 and Improved Orientation Sensor 2 fuse the Android Rotation Vector with the virtual Gyroscope sensor to achieve a pose estimation with a previously unknown stability and precision.
Apart from these two sensors, the following sensors are available for comparison:
- Improved Orientation Sensor 1 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - less stable but more accurate)
- Improved Orientation Sensor 2 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - more stable but less accurate)
- Android Rotation Vector (Kalman filter fusion of Accelerometer + Gyroscope + Compass)
- Calibrated Gyroscope (Separate result of Kalman filter fusion of Accelerometer + Gyroscope + Compass)
- Gravity + Compass
- Accelerometer + Compass
This application was developed for demonstrating the sensor fusion approach developed for my Master Thesis "Sensor fusion for robust outdoor Augmented Reality tracking on mobile devices" at the Human Interface Technology Laboratory New Zealand.
This project is an Gradle-based Android Studio project. It is also published in the Google Play Store, if you just want to try it out.
