What is it?
• Augmented reality (AR) is a term for a
live direct or indirect view of a physical
real-world environment whose
elements are merged with (or
augmented by) virtual computer-
generated imagery - creating a mixed
Augmented Reality (AR) is a variation of VE/VR.
• VR technologies completely immerse a user inside a
synthetic environment. While immersed, the user
cannot see the real world around him.
• In contrast, AR allows the user to see the real world,
with virtual objects superimposed upon or
composited with the real world.
AR supplements reality, rather than completely
replacing it. It creates the illusion that the virtual and
real objects coexisted in the same space.
AR can be thought of as the "middle ground“ between VE
(completely synthetic) and telepresence (completely real)
• AR enhances a user’s perception of interaction with the real world.
• The virtual objects display information that the user cannot directly
detect with his own senses.
• The information conveyed by the virtual objects helps a user perform

The military, particularly the Office of Naval Research and Defense
Advanced Research Projects Agency or DARPA, are some of the
original pioneers of augmented reality systems. One of the main uses
of augmented reality systems to the military is providing field soldiers
crucial information about their surroundings as well as friendly
troops and enemy movements in their particular area.
One of the interesting uses for AR in the medical field involves live interactive
imaging for assisting physicians, medical students and children. Minimally
invasive surgery (MIS) includes procedures where a camera is inserted into the
patient's body to help the doctor visualize the procedures he or she is conducting
This form of surgery is aided with the use of AR imagery
of a brain superimposed onto the patient's head, giving
the doctor a more tangible visualization.
Augmented Reality applications that can enhance textbooks to have
the power to engage a reader in ways that have never been possible.
Children learn better the lesson if they see it like a game.
In mathematics and geometry the main advantage of using an AR
system is that students actually see three dimensional objects.
AR in medicine, where an
“error” could drive to a disaster.
A surgeon learns laparoscopic surgery in an augmented reality
situation, there are no real consequences if mistakes are made during
training. These types of training provide opportunities for more
authentic learning and appeal to multiple learning styles.
Tells you exactly what stars, constellations, and satellites you’re looking at as
you point your device at the sky. The camera records both your position in
relation to the sky and where you’re pointing. It then presents information to
you about the cosmos. The app also has a feature called Time Machine that
shows you what the sky looked like in the past or will look like in the future.
Google Sky Map
This Android app lets you point your smartphone camera to
the sky and identify the stars, constellations, and planets above
you. Details and scenery change in real time as you move your
handset across the sky.
An iOS game that uses the to create level layouts for the game.
The game recognizes the images taken by the camera, redefines
them digitally, and incorporates them into the game world.
Tissot has launched the first augmented reality
window display at which allows consumers on the
street the chance to virtually "try-on" a 3D watch
from Tissot's pioneering T-Touch watch collection.
• Though Augmented Reality has both
advantages & disadvantages, it is a great
way of delivering entertainment media
that uses computer generated graphics
transposed over a real life scene.
