2. WHAT IS AUGMENTED
REALITY?
Augmented reality (AR) adds
digital content onto a live
camera feed, making that
digital content look as if it is
part of the physical
world around you.
3. HOW DOES IT
WORK?
First, computer vision understands what is in the
world around the user from the content of the
camera feed. This allows it to show digital content
relevant to what the user is looking at. This digital
content is then displayed in a realistic way, so that it
looks part of the real world - this is called rendering.
Since augmented reality is live, all the above has to
happen every time a new frame comes from the
camera. Most modern phones work at 30 frames per
second, which gives us only 30 milliseconds to do all
this. In many cases the AR feed you see through the
camera is delayed by roughly 50 ms to allow all this
to happen, but our brain does not notice!
4. SIMPLE USE CASE
Consider playing an augmented
reality board game using a real
cereal box as the physical support
like in the figure below. First,
computer vision processes the raw
image from the camera, and
recognizes the cereal box. This
triggers the game. The rendering
module augments the original frame
with the AR game making sure it
precisely overlaps with the cereal
box. For this it uses the 3D position
and orientation of the box determined
by computer vision.

6. 10 REAL USE
CASES FOR
AUGMENTED
REALITY
• Medical Training
• Retail
• Repair & Maintenance
• Design & Modeling
• Business Logistics
• Tourism Industry
• Classroom Education
• Field Service
• Entertainment Properties
• Public Safety
7. AUGMENTED
REALITY IN
HEALTHCARE
• Better routine care – This includes
everything from simple blood tests and
all the way to surgeries. For example,
even experienced doctors can have
trouble finding veins in the patient,
causing additional discomfort.
• Assisting doctors – Also, new tools have
been created to help doctors during
surgeries by allowing them to be
constantly aware of patient data during
the procedure.
• Interactive education – Before AR,
doctors had to read books and journals to
get an understanding of the material.
Nowadays, there are AR visualizations
that present this knowledge in greater
detail.
8. AUGMENTED
REALITY IN
EDUCATION
Interactive textbooks – Reading textbooks for
many hours is one of the most dreadful activities
for pretty much any student. However, thanks to
AR, the material contained in the textbook comes
to life.
Help with homework – When students leave the
classroom, they often have to deal with
homework problems on their own. They can
point their phone or tablets at the worksheet,
and immediately all kinds of hints and essential
information will pop out.
Safer lab experiments – When students conduct
chemistry and other experiments that involve
chemicals and dissection, there are many safety
procedures that need to be followed. In a
traditional classroom setting, this can be hard to
control, but with AR, students are always safe
even when something goes wrong.
9. AUGMENTED REALITY IN TOURISM
Better navigation – If you
love using apps like
Google Maps for getting
around, you will love the
AR version of them as
well. Basically, it
superimposes direction
and details on display,
rather than just
presenting you with a
map.
Information about sites –
When you are walking
about the city, the AR app
can automatically send
you notifications about
any landmarks or
important sites nearby. It
can also provide users
with all kinds of
information about a
particular building or
location as well.
Deciding where to go –
While it is possible to read
all kinds of brochures and
magazines about a
particular city or site, it
does not quite paint the
same picture as
experiencing it for
yourself. AR gives you the
ability to get a glimpse of
the location you are
considering to see if it is
worth traveling to.
11. AUGMENTED REALITY IN TODAY'S
WORLD
• Augmented reality is often presented as a kind of futuristic
technology, but a form of it has been around for years. For example,
the heads-up displays in many fighter aircraft as far back as the
1990s would show information about the attitude, direction and
speed of the plane, and only a few years later they could show
which objects in the field of view were targets.
• “While research in holography plays an important role in the
development of futuristic displays and augmented reality devices,
today we are working on many other applications, such as ultrathin
and lightweight optical devices for cameras and satellites,"
researcher Lei Wang, a doctoral student at the ANU Research
School of Physics and Engineering, said in a statement.
12. KEY BENEFITS OF
AUGMENTED
REALITY
AR increases engagement and interaction and provides a
richer user experience
Research has shown that AR increases the perceived
value of products and brands
Well implemented AR activity conveys innovation and
responsiveness from forward-thinking brands
AR is mobile and personal and, therefore, hugely
accessible to a rapidly growing smartphone market
AR is an inexpensive alternative to other media
platforms as no specific media needs to be purchased
Brands have access to detailed analytics enabling them
to truly understand their audience
13. THE CONS OF
AUGMENTED
REALITY
Cannot be Used Without the
Required Devices -Perhaps you
needed to show your client a
property, but you did not have a
smart phone, tablet or AR
headset on hand. Unfortunately,
you wouldn’t be able to show
your clients the property.
Technical Issues - If you have ever
used a laptop, computer, or cell
phone you know that technology
has its flaws. Sometimes it freezes
up, there is a glitch in the system,
etc., With augmented reality
relying so heavily on technology,
you face the potential issue of
having a technological issue.
Privacy Concerns - The downfall
to using technology is the threat
to a user’s privacy. Augmented
reality is a way to learn a lot
about a user and what they do.
14. THE FUTURE OF AUGMENTED REALITY
This doesn't mean that phones and tablets will
be the only venue for AR. Research continues
apace on including AR functionality in contact
lenses, and other wearable devices. The
ultimate goal of augmented reality is to create
a convenient and natural immersion, so there's
a sense that phones and tablets will get
replaced, though it isn't clear what those
replacements will be. Even glasses might take
on a new form, as "smart glasses"
are developed for blind people.
