Augmented Reality
Augmented Reality (AR) is a technology that overlays digital information, such as images, videos,
or 3D models, onto the real-world environment, enhancing the user's perception of reality.
It is the blending of virtual world and real life. AR uses technology to superimpose information
such as sounds, images and text on the real-world that we can see.
The virtual content is created by developers within applications and is designed to blend seamlessly
with the real-world content. AR users can interact with virtual content in the real-world and can
also distinguish between virtual and real content.
Tech Funda
Augment means to make greater in size or amount.
AR is not a new technology. It was first used in the display panels of fighter aircraft in the 1990s.
The panel displayed information about the altitude, direction and speed of the aircraft. A few
years later, the panels were upgraded to display target objects.
In 2009, Massachusetts Institute of
Technology’s developed SixthSense.
It is a small device worn like a pendant
that and combines the use of a
camera, small projector, smartphone
and mirror. The projector and the
camera are connected to the mobile
device in the user’s pocket. The
projector projects the visual
information on physical surfaces such
as walls and other objects. The camera
recognises and tracks the user’s hand
gestures with the help of computer-

vision techniques.
Google Glass, created in 2013, is an example of wearable AR
interface. It helps the user to remain focussed on the work.
It displays information on the user’s glass screen through a
small projector. It responds to voice commands to activate
an application any time.
