# Sensor-Fusion Demo for Android
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
- Accelerometer + Compass
|
||
|
|
- Gravity + Compass
|
||
|
|
- Android Rotation Vector (Kalman filter fusion of Accelerometer + Gyroscope + Compass)
|
||
|
|
- Calibrated Gyroscope (Separate result of Kalman filter fusion of Accelerometer + Gyroscope + Compass)
|
||
|
|
- 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)
|
||
|
|
- Old Android Orientation Sensor (Complementary filter fusion of Accelerometer + Gyroscope + 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"](http://my-it.at/media/MasterThesis-Pacha.pdf) at the [Human Interface Technology Laboratory New Zealand](http://www.hitlabnz.org).

## Build and Install
|
||
|
|
|
||
|
|
This project has an Eclipse project file for building and running the application. It is also published in the Google Play Store, if you just want to try it out.
