What is Augmented Reality (AR)?

 

 

AR is a live direct or live indirect view of a physical real-world environment, whose elements are augmented by a computer generated accessory (sound, video, graphic). AR involves the integration of digital information with live video of the environment in real time.

It takes the existing picture while blending new information into it, resulting in a computer generated environment.

 

In AR, the view of reality is modified and ones perception is enhanced by replacing real world imagery with simulated ones. The end result is that it blurs the line between what’s real and what’s computer enhanced by taking graphics from the television screen and/or computer and integrating them into real-world environments. The goal is to create a system in which the user cannot tell difference between real world and virtual augmentation.

AR is used in military training, entertainment, engineering, robotics, CAD programs, and by advertisers to create 3D renders of products. 

Video games and cell phones drive AR, and it is useful when tied into location based technology. The key to AR is the software, which is written in special 3D augmented reality programs that allow the developer to tie in animation or contextual information into the computer program. 

To experience AR, the user must download a plugin or software application (flash or shockwave for example) and when incorporated with advanced AR technology (adding computer vision and object recognition), the information becomes interactive and digitally manipulable.

The process involves digitally rendering images, giving the sense of illusion or virtual reality.

Examples of AR use:

  • changing maps behind weather reporters
  • visual displays and audio guidance for complex tasks
  • virtually trying on clothes while webcam shopping
  • historical recreations integrated with current environment
AR is virtual reality that aims to duplicate the world’s environment in a computer by generating a composite view for users that have a combination of the real scene and the virtual scene, that have been generated by the computer which will then enhance the users sensory perception. The concept is that reality is modified by a computer, enhancing one's perception of reality by allowing technology functions by enhancing reality; replacing the real world with a simulated one.
