"the basic types of Augmented Reality: 1. Surface– The most understandable form of reality that is augmented would be screens, floors, walls etc that respond to the touch of people in them providing them w/virtual real time information. 2. Pattern– The AR system performs simple pattern recognition on a shape, marker (usually on a framed card in the real world scene) or face & replaces it w/a static or moving element. 3. Outline– This is where your hand, eye or body outline is picked up & seamlessly merged w/the virtual elements. Simple ex. where you can pick up a 3D object that doesnt exist because the system is tracking your hand outline. 4. Location– Based on detailed GPS or triangulation location & position/view of the camera/device the system can overlay information precisely over buildings or people as you move through real space. 5. Hologram– Using smoke & spinning mirrors literally in some cases, virtual or real items are projected in & interacted w/ the physical space"
