But now, thanks to your smartphone, you can now experience augmented reality with the help of apps. Whether you use an iOS device, Android device, BlackBerry or Symbian3 smartphone, you can get free AR apps for various purposes.

You could play a shoot-em-up game, with your enemies appearing on a live view of the room around you.
