4. INTRODUCTION
Augmented reality superimposes information in our field of view.
It takes us into a world where real and virtual worlds are tightly coupled.

5. LITERATURE SURVEY
In 1997, a survey was published which described many problems
and summarized the developments up to the point.
In the late 1990s, several conferences, workshops and symposiums
on Augmented reality was conducted.
Mixed Reality Systems Laboratory in Japan and Project ARVIKA in
Germany focused on AR.

7. VIRTUAL REALITY
Virtual reality is an environment which is computer simulated and the
simulation could be that of an imaginary world.

8. 1. Virtual reality (VR) is an
artificial, computer-generated
simulation or recreation of a
real life environment or
situation.
2. Virtual reality creates its own
reality that is completely
computer generated and
driven.
1. Augmented reality (AR) is a
technology that layers
computer-generated
enhancements atop an existing
reality.
2. Augmented reality enhances
experiences by adding virtual
components as a new layer of
interaction with the real world.

VR vs AR

10. 10
 Augmented reality and virtual reality are inverse reflections of one
in another.
 Virtual reality offers a digital recreation of a real life setting, while
augmented reality delivers virtual elements as an overlay to the
real world.

11. BEST PRACTICES OF AR

12. CONTEXT-SENSITIVE INFORMATION -
INFORMATION AT RIGHT TIME AND PLACE
AR Gadget gives information relevant to the real world object.

13. ENHANCES SENSES
AR gadgets can sense the real world thus giving us real-time information on
weather and all other user specific details.

14. EXPLORING THE VIRTUAL IN REAL
These so-called mixed-reality simulations allow users to dynamically
adapt or change virtual objects in the real environment.

15. VIRTUAL INTERFACES –
CONTROLLING THE REAL THROUGH VIRTUAL
Virtual interfaces, focuses on AR technologies that offer new options
for controlling real-world objects through digital means.

by Fraunhofer Institute for Medical Image
Computing MEVIS in Germany.
 VR Dentist is a dental app that uses virtual
and augmented reality for educational
purposes.
 Vipaar - A remote surgeon could essentially
project his hands into the display of a
surgeon on site wearing Glass and point and
guide.
 AccuVein

HARDWARE OVERVIEW
 Hand-held Devices
 Stationary AR Systems
 Spatial AR systems
 Head Mounted Displays
(HMDs)
 Heads Up Displays (HUDs)

SOFTWARE OVERVIEW
The software must derive real world coordinates, independent from the
camera, from camera images by a process called image registration .
Augmented Reality Markup Language (ARML) is a data standard
developed within the Open Geospatial Consortium (OGC), which consists
of XML grammar to describe the location and appearance of virtual
objects in the scene.
Some of the well known AR SDKs are offered by Vuforia, AR Toolkit,
Catchoom CraftAR, Mobinett AR, Wikitude, Blippar, Layar, and Meta.

26.  Perceived as the technology of the future.
 Changing perspective and transforming surrounding.
 Revolutionising company’s business models.
 One day might surpass smartphones as the dominant way people
interact with computers.
 It seems the average customer isn’t as eager to pay US $600 for
bulky goggles simply to peruse the rather limited catalogue of
available VR content.
 Can only succeed if people are educated about the true worth of the
products.
FUTURE OF
AUGMENTED REALITY
26

27. CONCLUSION
Augmented reality (AR) is quickly becoming an important technology
in the enterprise.
Bridges the digital world and the physical world .
Covered a long way from a science-fiction concept to a science-based
reality.
AR or augmented reality has gone from pipe dream to reality in just
over a century.
However, AR is limited by a highly fragmented ecosystem of
hardware platforms and operating systems.
A new step towards a better future.
