Augmented Reality

Ronald Azuma defines an augmented reality system as one that:Combines real and virtual world aspectsIs interactive in real-timeIs 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 Glasseseye wear that employs cameras to intercept the real world view and re-display it's augmented view through the eye pieces

Display

Contact LensesContain the elements for display embedded into the lens including integrated circuitry, LEDs and an antenna for wireless communication.Under development

Virtual Retina Displaya personal display device under development .a display is scanned directly onto the retina of a viewer's eye.

Handhelda 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.
