This document provides an introduction to augmented reality (AR). It defines AR as combining real and virtual scenes viewed by a user. The history of AR is traced back to 1968 with Ivan Sutherland's head-mounted display system. The ultimate goal of AR is for users to not be able to distinguish between real and virtual elements. AR is compared to virtual reality in that AR augments the real world while VR provides totally immersive virtual environments. Examples of AR applications discussed include medical, entertainment, military training, education, and more. Display techniques like head-mounted displays, eyeglasses, contact lenses, and handheld devices are also outlined.

2. Topics to discuss:
• Augmented Reality
• Augmented Reality System
• How it Works
• Display techniques
• AR vs VR
• Technology
• Applications & Examples

3. What is Augmented
Reality?
• 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.

5. History:
• The first AR technology was
developed in 1968 at Harvard when
computer scientist Ivan Sutherland
(named the “father of computer
graphics”) created an AR head-
mounted display system.

6. What is the Goal of AR?
• To enhance a person’s performance
and perception of the world.
• But, what is the ultimate goal???

7. The Ultimate Goal of AR:
• Create a system such that a user CANNOT
tell the difference between the real world
and the virtual augmentation of it.

8. Augmented Reality vs.
Virtual Reality
• System augments the
real world scene.
• User maintains a sense
of presence in real
world.
• Needs a mechanism to
combine virtual and
real worlds.
•Totally immersive
environment.
•Visual senses are
under control of
system.
•Hard to make VR
world interesting.

9. AR vs VR

10. Miligram’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.
Mixed Reality (MR)
Real
Environment
Augmented
Reality
Augmented
Virtuality
Virtual
Environment

11. ➢The difference between the two terms comes
down to where the user interaction takes place. If
the interaction happens in the real world, it is
augmented reality. If the interaction occurs in a
virtual space, it is considered augmented virtuality.

12. 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 is ‘REAL’.

13. Examples:

14. 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

15. ➢Head-mounted
display:
➢Eye
Glasses:

16. DISPLAY:
Contact Lenses
• Contain the elements for display
embedded into the lens including
integrated circuitry, LEDs and an antenna
for wireless communication.
Handheld
• a small display that fits in a user's hand.
• Portable.

17. ➢Contact
Lenses:
➢Handheld:

18. Pros of augmented-
reality:
• Experience the World
From Your Living Room.
• It enhances the
knowledge and data of
the people.
• The games of augmented
reality furnish more real
experience.

19. Cons of augmented-
reality:
• Invades Privacy.
• It has the feature of
spam.
• The avail of augmented
reality in social situations
is improper.
• Hampers Interaction
With Real-World.

20. Applications:
• Medical
• Entertainment
• Military Training
• Engineering Design
• Robotics and Telerobotics
• Manufacturing, Maintenance, and Repair
• Consumer Design
• Hazard Detection
