Augmented Reality (AR) is the application of technology to superimpose information on digitally rendered images into real world environments to give a sense of virtual reality or create an illusion. For example, images and sounds are superimposed over what users see and hear.
Unlike Virtual Reality where computer generated environments are used to interact with human beings and human beings get immersed into them, AR takes the real world of the present and projects digital imagery and sound into it.
The presentation of augmented reality is in some form of futuristic technology, despite the fact that it has been around for many years. For example, the heads-up display in many fighter jets utilizes the principles of augmented reality, and this date back to the early 1990s when they were used to show information about altitude, speed and direction of the aircraft.
