About this app

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:

- 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
- Deprecated Android Orientation Sensor (Complementary filter fusion of Accelerometer + Gyroscope + Compass)

The source code is publicly available and the link can be found in the About-section.

This is a research application. Please, rate it only if you understand it. It is an awesome piece of software. By the way, I'm not connected with the authors

I can't see any 3D cube but just 2D planes. Is that normal? Thanks.

Woul be interesting to include Madgwick 2010 filter and some cpu load indication.

Sounds like a useful extension. If you can implement that, I'm happy to add it to the app. Just create a PR: https://bitbucket.org/apacha/sensor-fusion-demo

What's new

Changed the main setting to default to the "room mode" instead of the cube mode. Long-click can still toggle between the two modes.
The app was also updated to the latest SDK to remain active in the Google Play Store.
