This Cool AR Creator firstly uses the built-in camera of the mobile device to capture the specific image within the live view of the reality.
The image being captured would then trigger an Overlay.
The Overlay may be a video, an animation, a 3-D object, another image, a link to a website or any combinations.
In short, Reality (1) + Overlay (1) = (Reality integrated with Overlay) (2) = Augmented Reality Action (or in short "Aura")
What kinds of Augmented Reality you may create? Your imagination is the only limit.
