Conclusion
Augmented Reality
Ronald Azuma defines an augmented reality system as one that:
Combines real and virtual world aspects
Is interactive in real-time
Is registered in three dimensions
Simple Example of Augmented Reality
Lbw decisions in cricket is a very basic example
History and Development
 1960s -The first AR system was developed by Ivan Sutherland and his
students at Harvard University and the University of Utah.
 1970s and 1980s - augmented reality was studied at institutions such as the
U.S. Air Force's Armstrong Laboratory, the NASA Ames Research Center
and the University of North Carolina at Chapel Hill.
 Early 1990s- the term "augmented reality" was coined by scientists.
 Presently-Augmented reality is still in an early stage of research and
development at various universities and high-tech companies.
Augmented reality system
 Adds virtual computer-generated objects
 Audio
 Other sense enhancements to a real-world environment in real time.
Goal of AR
 To enhance a person’s performance and perception of the world
 But, what is the ultimate goal????
AR Vs VR
Augmented Reality
 The user sees the real world but
with the addition of computer
generated images which are
overlaid on various objects
within the real world
Virtual Reality
 Is based upon a complete
simulation of a real world
environment which the user can
explore and interact with by means
of a head mounted display (HMD)
and input device.
AR Vs VR
Augmented Reality
 Augmented reality enhances
real life with artificial images.
Virtual Reality
 Virtual reality replaces the real
with the artificial.
Milgram’s reality-virtuality continuum
Miligram coined the term “Augmented Virtuality” to identify systems which
are mostly synthetic with some real world imagery added such as texture
mapping video onto virtual objects.
This is How AR works
 Pick A Real World Scene
 Add your Virtual Objects in it.
 Delete Real World Objects
 Not Virtual Reality since Environment Real.
Advantages of AR
 Give better experience to user.
 Enhancing the world by relevant information.
 Setting a new market.
Display
 Head-mounted Display(HMD)
device paired to a headset such as
a harness or helmet
 Eye Glasses
eye wear that employs cameras to
intercept the real world view and
re-display it's augmented view
through the eye pieces
Display
 Contact Lenses
Contain the elements for display
embedded into the lens including
integrated circuitry, LEDs and an
antenna for wireless
communication.
Under development
 Virtual Retina Display
a personal display device under
development .
a display is scanned directly onto
the retina of a viewer's eye.
 Handheld
a small display that fits in a user's hand.
Portable
Universal
Physical constraints of the user having to hold the device
 Spatial
makes use of digital projectors to display graphical
information.
user is not required to carry equipment or wear the
display over their eyes.
can be used by multiple people at the same time without
each having to wear a head-mounted display.

Future of AR
Military:
The Office of Naval Research has sponsored AR research
AR system could provide troops with vital information about their
surroundings.
Medical:
Superimpose an image from an MRI onto a patient’s body.
This might allow surgeons to pinpoint a tumor to remove.
Education:
Used in labs where students can learn more about the experiments they are
participating in.
Future of AR
 Gaming:
• ARQuake is an AR version of the
popular game Quake.
• 1st person shooter that allows the user
to run around in the real world while
playing a game in the computer
generated world.
• Uses GPS, a hybrid magnetic and
interior orientation sensor, gun
controller, and a standard laptop carried
in a backpack.
Issues in AR
 Performance Issues
Real time processing of images can be a challenge and often can slow down
augmented reality systems.
 Interaction Issues
Users within a mixed environment because of augmented reality have difficulties
interacting with the environment as normal.
 Alignment Issues
People working in an augmented reality are more sensitive to alignment errors.
Proper calibration and alignment with the reference frame of the world is crucial.
Why Continue Research in AR
 AR systems will instantly recognize what someone is looking at, and
retrieve and display the data related to that view.
 There are hundreds of potential applications for such a technology,
gaming and entertainment being the most obvious ones.
 Any system that gives people instant information, requiring no research
on their part, is bound to be a valuable to anyone in any field.

  • 4. Simple Example of Augmented Reality Lbw decisions in cricket is a very basic example
  • 5. History and Development  1960s -The first AR system was developed by Ivan Sutherland and his students at Harvard University and the University of Utah.  1970s and 1980s - augmented reality was studied at institutions such as the U.S. Air Force's Armstrong Laboratory, the NASA Ames Research Center and the University of North Carolina at Chapel Hill.  Early 1990s- the term "augmented reality" was coined by scientists.  Presently-Augmented reality is still in an early stage of research and development at various universities and high-tech companies.
  • 6. Augmented reality system  Adds virtual computer-generated objects  Audio  Other sense enhancements to a real-world environment in real time.
  • 7. Goal of AR  To enhance a person’s performance and perception of the world  But, what is the ultimate goal????
  • 8. AR Vs VR Augmented Reality  The user sees the real world but with the addition of computer generated images which are overlaid on various objects within the real world Virtual Reality  Is based upon a complete simulation of a real world environment which the user can explore and interact with by means of a head mounted display (HMD) and input device.
  • 9. AR Vs VR Augmented Reality  Augmented reality enhances real life with artificial images. Virtual Reality  Virtual reality replaces the real with the artificial.
  • 10. Milgram’s reality-virtuality continuum Miligram coined the term “Augmented Virtuality” to identify systems which are mostly synthetic with some real world imagery added such as texture mapping video onto virtual objects.
  • 11. This is How AR works  Pick A Real World Scene  Add your Virtual Objects in it.  Delete Real World Objects  Not Virtual Reality since Environment Real.
  • 12. Advantages of AR  Give better experience to user.  Enhancing the world by relevant information.  Setting a new market.
  • 13. Display  Head-mounted Display(HMD) device paired to a headset such as a harness or helmet  Eye Glasses eye wear that employs cameras to intercept the real world view and re-display it's augmented view through the eye pieces
  • 14. Display  Contact Lenses Contain the elements for display embedded into the lens including integrated circuitry, LEDs and an antenna for wireless communication. Under development  Virtual Retina Display a personal display device under development . a display is scanned directly onto the retina of a viewer's eye.
  • 15.  Handheld a small display that fits in a user's hand. Portable Universal Physical constraints of the user having to hold the device  Spatial makes use of digital projectors to display graphical information. user is not required to carry equipment or wear the display over their eyes. can be used by multiple people at the same time without each having to wear a head-mounted display. Display
  • 20. Future of AR Military: The Office of Naval Research has sponsored AR research AR system could provide troops with vital information about their surroundings. Medical: Superimpose an image from an MRI onto a patient’s body. This might allow surgeons to pinpoint a tumor to remove. Education: Used in labs where students can learn more about the experiments they are participating in.
  • 21. Future of AR  Gaming: • ARQuake is an AR version of the popular game Quake. • 1st person shooter that allows the user to run around in the real world while playing a game in the computer generated world. • Uses GPS, a hybrid magnetic and interior orientation sensor, gun controller, and a standard laptop carried in a backpack.
  • 22. Issues in AR  Performance Issues Real time processing of images can be a challenge and often can slow down augmented reality systems.  Interaction Issues Users within a mixed environment because of augmented reality have difficulties interacting with the environment as normal.  Alignment Issues People working in an augmented reality are more sensitive to alignment errors. Proper calibration and alignment with the reference frame of the world is crucial.
  • 23. Why Continue Research in AR  AR systems will instantly recognize what someone is looking at, and retrieve and display the data related to that view.  There are hundreds of potential applications for such a technology, gaming and entertainment being the most obvious ones.  Any system that gives people instant information, requiring no research on their part, is bound to be a valuable to anyone in any field.
