4. WHAT IS AR? • A combination of
• A real scene viewed by a user and
• A virtual scene generated by a
computer that augments the scene
with additional information
Augmented reality is defined as a real time
direct or indirect view of a physical real world
environment that has been augmented by
adding virtual computer generated
information to it.

6. AUGMENTED REALITY
VS VIRTUAL REALITY
AR
System augments real
world scene
User maintains sense
of presence in real
world
Needs mechanism to
combine virtual & real
worlds
Hard to register real &
virtual
VR
Totally immersive
environment
Senses are under
control of system
Need mechanism to
feed virtual world to
user
Hard to make VR world
interesting
7. AR Hype Cycle
•AR grabs marketer’s attention.
•Research needs to be carried out.
•As AR moves up on the slope, it should really
take care on how it can use these new
developments in providing a good and
valuable experience to the user
•The Gartner curve seems to be progressing
slowly with the help of 2D images and videos
8. USES OF AR In the following slides we will be
covering the application in
Manufacturing in detail…
• Entertainment
• Military training
• Engineering design
• Manufacturing and other processes
• Marketing
• Simulation
• Navigation
• Medical
9. DISPLAY
TECHNOLOGIES
• Monitor based
• Laptops
• Cell phones
• Projectors
• Head mounted displays
• Video see-through
• Optical see-through
Augmented reality can be created on
multiple platforms depending on the use and
maturity in technology
10. MONITOR BASED AR • Simplest available
• Treat laptops/PDA/cell phones as a
window through which you can see
AR world
Majorly used in Product development &
Prototyping
11. OPTICAL SEE-
THROUGH HMD
Optical see through HMD’s work by
placing optical combiners in front of
the user’s eyes. These combiners
are partially transmissive, so that
the user can look directly through
them to see the world
Used in Assembly and Servicing
12. ASSEMBLY • Examples
• Boeing –For assembly of airplanes. -
information to workers inform of
diagrams, voice over instructions and
illustrations
• Furniture assembly system –
ARToolkit is used for tracking and
assembly instruction augmentation.
• Training-Deliverance of assembly
information and instructions
• Information about assembly (instruction
manuals, drawings or semantics)
• detached from equipments
• paper manual or electronic manual
• It leads to inefficiency and error because
of switching in workspace
• It places the digital assembly
information in the area of view of
operator
• Roadblock -what kind of information has
to be shared virtually and where and in
what proportion
13. MAINTENANCE,
SERVICE, REPAIR AND
INSPECTION
Examples
• An aircraft mechanic can see virtual
information panels ->real image of a jet
engine +‘‘see through’’ machinery without
disassembling it.
• A technician working on CPU and receives
step-by-step instructions servicing it
• Remotely operated vehicles (ROVs) in a
dangerous environment where user cannot
go
• Underground pipe inspection, maintenance
• Used for aircraft maintenance and repair .
• Quality assurance of inspectors in food
processing
Superimposition of images, voice instructions
over the actual equipment providing step by
step information
14.
15. MANUFACTURING
LAYOUT
• A physically existing production
environment is superimposed with
virtual objects
• AR based systems provide an
interactive interface
• It assists users in modelling,
validation of the simulation model,
and the subsequent optimization of
the production system
• Focus is on design-test-verify
approach
AR simulation is used to create effective and
efficient production systems
Through this method product and process
development cycles are sought to be
shortened
16. TELE-ROBOTICS
• AR used to enhance interaction between
humans and robots
• Operator uses a visual image that
contains details and other significant
points about the scene and superimposes
it over the scene
• This allows operation & inspection of
equipment in difficult and/or hazardous
environments
• This process reduces the learning time
and increases the intuitiveness of the
programming process
It involves controlling robots remotely to
perform certain activities in the real world
However, currently tele-robotics doesn’t
come with the desired level of accuracy or
control
17. PRODUCT
DEVELOPMENT
New Augmented Tangible Interfaces
(ATI) -can be used for
• 3D browsing
• 3D position/orientation
• 3D assembly/disassembly
• To take care of the design process
Multiuser collaborative AR
• Help in interaction between experts
that are located at geographically
dispersed locations
AR can be used as a tool to simulate the
product development
Mixed prototyping approach- Mock non-
reconfigurable parts with 3D prototypes.
User to assess and evaluate the synthetic
prototypes in the environment directly.

21. FUTURE SCOPE Content for AR Applications
• Better content and/or contexts are required to make better
AR research and prototypes.
• Better applications are mostly in a better position to drive
the research into new groundbreaking projects.
A Need for Cross Fields Research
• Tracking and Positioning are some of the Major problems
for AR
• Artificial Intelligence as a field can provide various
technologies that can be extremely helpful in creating AR
systems that can be implemented in several specific
problem domains common systems.
It is following a sciatic process which is a
rather slow moving process
It should primarily focus on developing and
exploring the basic ideas and enabling
technologies of Augmented Reality.
