The expression virtual reality is usually used to describe imaginary worlds that only subsist in our minds and computers. Virtual Reality is an interactive, computer generated, three dimensional surrounding in which a person is immersed whereas augmented reality adds cues into the already existing world. It allows a digitally enhanced view of the real world and unites you with more significant substance in your daily life.
Augmented reality is different from virtual reality. Virtual reality: You only see the virtual aspect. But with augmented reality — you can still see the real world. It provides you with authentic information but does not replace the real world you’re experiencing. True virtual reality completely blocks out the real world whereas augmented reality adds to the already existing real world.
In the case of virtual reality one enters into an entirely immersive world, with the help of a computer system. Everything around the user is made fictitious by the system. This may display inside a blank room or other device that allows the user to feel present in the virtual surrounding. Some virtual reality also present aspects like feedback in the form of sound or touch to allow the user to interact with objects and spaces. This replicates real-world experiences in an entirely built environment.
However, augmented reality manifests in the real world, with added virtual factors. These include sensation, reverberation, or images produced by a system. The goal of augmented reality is to create a system in which the user cannot express the difference between the real and virtual world. Advertising campaigns that involve projections of images into real-world spaces are another type of augmented reality. In the form of gesture based apps, tablets and smart phones have discovered augmented reality experience. With use of the camera in smart phones, an augmented reality android app can allow users to visualize 3D objects such as characters from books or rooms with furniture etc.
The application of augmented reality and virtual reality are substantial. They are of interest to many industries which are looking for various ways to appeal to new patrons.
