Augmented Reality is a new solution that can be used on any kind of device with a camera. All you need is a marker and you can mix reality with vitrual world. After identifying the marker, our device (pc, laptop, pda or any kind of smart phone) assigns a virtual 3D object that appers on the marker, and moves, turns along with the movement of the marker. So on the screen of your device you can see a virtual 3D picture, video or animation in the real environment.
Once you printed a marker on an invitation card, leaflet, package etc, you can assign different content to the same marker time to time.
