Sensor fusion

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 3D compass 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)

Ratings and reviews

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.

Hi real name is Stephen can you add a ability to use the app in the background so I can do virtual reality as I don't have a gyroscope on my device am I on my mom's so really old phone

What's new

Complete overhaul of the user interface into a 3D compass.
