In Augmented Reality (also called AR), graphics, sounds, and touch feedback are added into our natural world to create an enhanced user experience.

1. Augmented Reality

2. An enhanced version of reality where
live direct or indirect views of physical
real-world environments are
augmented with
superimposed computer-generated
images over a user’s view of the real-
world, thus enhancing one’s current
perception of reality.

touch feedback are added into our

3. Applications of augmented reality can be as
simple as a text-notification or as complicated
as an instruction on how to perform a life-
threatening surgical procedure.

4. How Does Augmented Reality
(AR) Technology Work?
 In most augmented reality applications, a
user will see both synthetic and natural
light.
 This is done by overlaying projected
images on top of a pair of see-through
goggles or glasses, which allow the images
and interactive virtual objects to layer on
top of the user’s view of the real world.
 Augmented Reality devices are often self-
contained, they are completely untethered
and do not need a cable or desktop
computer to function.

5. Types of Augmented Reality:
Marker Based Augmented Reality
Marker-based augmented reality (also
called Image Recognition) uses a
camera and some type of visual
marker, such as a QR/2D code, to
produce a result only when the marker
is sensed by a reader.
Markerless Augmented Reality
Markerless augmented reality, uses a
GPS, digital compass, velocity meter,
or accelerometer which is embedded
in the device to provide data based on
your location.

6. Projection
Based Augmented Reality
It works by projecting artificial light
onto real world surfaces, allow for
human interaction by sending light
onto a real world surface and then
sensing the human interaction (i.e.
touch) of that projected light.
Superimposition
Based Augmented Reality
Superimposition based augmented
reality either partially or fully
replaces the original view of an
object with a newly augmented
view of that same object.

real-world environment
Full immersion in
