 In fundamental terms, the expression augmented
reality, often abbreviated to AR, refers to a simple
combination of real and virtual (computer-generated)
worlds.
 Given a real subject, captured on video or camera, the
technology 'augments' (= adds to) that real-world
image with extra layers of digital information.
 Combining digital information, photographs and 4G
video, streets are represented by three-dimensional
graphics which even allow the user to enter buildings
and see a live video stream.

3.
 A notable example of an augmented reality app is
Recognizer, which links face recognition software to
social networking profiles. This means that you could
simply capture a person's image in your mobile's
viewfinder, and potentially have access to their
identity, contact details and a range of personal
information.
Most Augmented Reality
research focuses on see-
through devices, usually worn
on the head that overlay
graphics and text on the
user's view of surroundings.

4.
 Just as monitors allow us to see text and graphics
generated by computers, head-mounted displays
(HMDs) will enable us to view graphics and text
created by augmented-reality systems.

5.
 There are two basic types of HMDS:
◦ optical see-through
◦ video see-through

 Handheld Augment Reality employs a small
computing device with a display that fits in a
user's hand. Handheld AR employed sensors such
as digital compasses and GPS units for its six
degree of freedom tracking sensors.

7.
 Spatial Augmented Reality (SAR) makes use of
digital projectors to display graphical
information onto physical objects.

8.
 Objects in the real and virtual
worlds have to be properly
aligned with respect to each
other.
 Some applications demand
accurate registration., e.g., virtual
surgery where error can be fatal!!
 Registration errors can also cause
motion-sickness.

 Technological Limitations:
◦ Displays, trackers, and AR systems in general need
to become more accurate, lighter, cheaper, and less
power consuming.
◦ The display isn’t very bright and completely washes
out in bright sunlight.
◦ The equipment isn’t nearly as portable as desired.
Since the user must wear the PC, sensors, display,
batteries, and everything else required.
 User Interface Limitations:
o Need a better understanding of how to display data
to a user and how the user should interact with the
data.

11.
 AR has a great future
as it promises better
navigation and
interaction with real
and virtual world in
ways which has
previously been
unimaginable.
