Augmented Reality

Augmented Reality is a technology that superimposes sounds, images and text on the real world
that we can see. Images 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 people to work in real-life
environments by creating a simulation of the
reality. for example, flight simulators for pilots.

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. 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. It displays 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 almost always 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. Simulator devices, surgeons can develop
their surgical skills through simulation on digital patients
and architects can create a walk-through model of their projects .

Examples of AR & VR Applications

• Google Earth VR app lets you travel to any place on planet Earth and the moon.
• Ikea Place app allows you to envision furniture in your own home, by overlaying a 3D
representation in your room.

• YouCam Makeup app lets you virtually try on real-life cosmetics on a selfie.
