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.
