A free app for Android, by Alexander Pacha.
This is a virtual app for the Android platform that is designed to demonstrate the capabilities of various sensors and sensor-fusions.
You can play with the virtual sensors, which are a combination of the accelerometer, gyroscope, and compass. It will give you the information in the form of a cube that can be rotated by rotating the device.
You can compare the results of different sensor-fusions and choose the combination that is best for you.
This app is designed to work on Android devices that have a sensor fusion that can be used to determine the position and orientation of the device.
