GyroDroid

This is the demo application for GyroDroid, a Unity3D plugin which enables access to the native Android sensors.

So far Unity has only built-in support for the accelerometer sensor on Android mobiles.This package provides access to every single sensor of your Android device!
It can be used for augmented reality, multisensoric games, visualization and more.

See the forum thread for more information.

The package comes with several nice demo scenes (including a nice rotating robot, and a superdroid).

You can buy the package in the Unity Asset Store.
