=== AR, What Is It? ===
Augmented Reality (AR) is a technology that enhances a user’s real-world experience through digital features. AR uses technology to implement the experience such as object recognition, object tracking, and content rendering. To recognize objects, objects must first be identified and analyzed, then AR imposes a digital image overlayed on the object.  For AR applications that use object tracking, real-world objects are identified and tracked, then a digital image placed over them. For either of these to happen, virtual content must be rendered onto the real-world via content rendering.
