What is Augmented Reality (AR)?

 
Augmented Reality (AR) overlays virtual objects on the real-world environment. Augmented reality (AR) overlays computer-generated content on top of the real world. This superimposed digital overlay can superficially interact with the environment in real time. AR is primarily experienced via a wearable glass device or through smartphone applications.
 
Augmented reality offerings layer over what an individual is seeing through a device. That layer could be a Pokémon, or it could be a text explanation of how mummification worked in ancient Egypt. Augmented reality typically requires an application (app) on a phone or tablet to be used in order for the individual to see the extra layer of information.  Augmented reality triggers can be GPS points or images viewed through the lens of the camera on the device.
 

The Difference Between AR and VR

 
Virtual Reality and Augmented Reality are two sides of the same coin. You could think of Augmented Reality as VR with one foot in the real world: Augmented Reality simulates artificial objects in the real environment; Virtual Reality creates an artificial environment to inhabit.

In Augmented Reality, the computer uses sensors and algorithms to determine the position and orientation of a camera. AR technology then renders the 3D graphics as they would appear from the viewpoint of the camera, superimposing the computer-generated images over a user’s view of the real world.

In Virtual Reality, the computer uses similar sensors and math. However, rather than locating a real camera within a physical environment, the position of the user’s eyes are located within the simulated environment. If the user’s head turns, the graphics react accordingly. Rather than compositing virtual objects and a real scene, VR technology creates a convincing, interactive world for the user.
