Augmented Reality and Virtual Reality

                 Augmented  Reality  (AR)  and  Virtual  Reality  (VR) bridge  the  digital  and  real  worlds.  Both  these
                 technologies find the greatest use in entertainment, sports/gaming, close interactive eye to eye
                 communication and aided shopping experiences. Imagine sitting at home and browsing through a
                 store in London where you can see and feel the merchandise you wish to buy. This technology is also
                 used in education. Imagine being a live participant in a historical battle or a student of anatomy
                 in medical school. You can really feel the sensation of being in the battle or interact with virtual
                 anatomical models for more immersive learning experience.

                 Augmented Reality

                 Augmented  Reality  is  a  technology  that  superimposes
                 sounds, images and text on the real world that we can see.
                 Images, information,  content  and  interactive  elements
                 are created by developers within applications that blend
                 in with content in the real world.
                 AR is used in:

                    creating  an  imaginary  world  for  the  purpose  of
                    entertainment  and  gaming,  for  example,  3D  movies,
                    video games, etc.
                    training software and help people to learn to work in
                    real-life environments by creating a simulation of the reality. For example, flight simulators for
                    pilots  to practice their skills in the condition of danger without actual risk.
                 Examples of AR experiences include Snapchat lenses and the game Pokemon Go. Disney coloring
                 book with AR has a character in the book to colour and the colored characters come to life on a
                 3D screen. The app uses the camera to detect the character that was coloured and recreates the
                 character in a 3D form on the screen. Google Glass created in 2013 is an example of wearable
                 AR interface. It helps the user remain focussed on the work while receiving digital information.
                 It displays information on the user’s glass screen through a small projector. It responds to voice
                 commands to activate an application any time

                 Virtual Reality

                 Virtual Reality is a technology that creates a complete virtual world that users can interact with.
                 In this world, you can experience places as if you were actually there. While using virtual reality,
                 the user typically wears VR devices such as HTC Vive or Google Cardboard. These devices have
                 eye-covering headset and headphones to completely replace the real world with the virtual one.
                 Using VR Simulator devices, surgeons can develop their surgical skills through simulation on digital
                 patients and architects can create a walk-through model of their projects.
