3Augmented 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

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
Can increase knowledge and information. People can share experiences with each other in real time over long
distances. Games that provide an even more "real" experience. Things come to life on people's mobile. Form of escapism.

Display
Head-mounted Display(HMD)device paired to a headset such as a harness or helmet
Eye Glasseseye wear that employs cameras to intercept the real world view and re-display it's augmented view through the eye pieces

a small display that fits in a user's hand.Portable UniversalPhysical constraints of the user having to hold the device
Spatialmakes 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 researchAR 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 IssuesReal time processing of images can be a challenge and often can slow down augmented reality systems.
Interaction IssuesUsers within a mixed environment because of augmented reality have difficulties interacting with the environment as normal.
Alignment IssuesPeople 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.
