“(AR) is an interactive experience of a real-world environment
where the objects that reside in the real-world are enhanced by
computer-generated information”
Introduction to Augmented Reality

5. 8/14/2019 Academy Of Technology 5
 Combine real world and virtual world environment
 Run interactively
 Run in real-time
 Registers real and virtual information together
Properties of Augmented Reality

6.  break out of the confines of our screens.
enhance a person’s performance and perception of the world.
 create deeper human connections.
Goals of Augmented Reality

7.  1901 – First recorded reference to AR by L. Frank Baum.
 1960 – Ivan Sutherland creates first see through HMD
 1990 – Tom Caudell, coins the term ‘augmented reality’
 1997 – Azuma published a survey
 Since then, AR’s growth and progress have been remarkable.

Real world Applications

9. Augmented Reality Vs Virtual Reality
Virtual Reality
•Immersive environment
•Senses are under control of system
•Need a mechanism to feed virtual world to
user
•Hard to make VR world interesting
Augmented Reality
•Enhances the real world scene
•Sense of presence in real world
•Needs a mechanism to combine virtual
and real worlds
•Hard to register real and virtual

11. Head-worn Display
8/14/2019 Academy Of Technology 11
 Mount this type of display on head
 Forms image directly on the retina
 Advanced AR

12. Handheld Display
8/14/2019 Academy Of Technology 12
 Use handheld flat-panel displays
 Acts as a window

13. Projection Based Display
8/14/2019 Academy Of Technology 13
 projected directly on physical objects
 Can cover large surface

14. Challenges with AR development &
Adoption
1) Limited Hardware Capabilities
2) Software issues
3) Unsatisfying Experience
4) Uncomfortable Architecture
5) Public Acceptance
8/14/2019 Academy Of Technology 14

15. Issues faced by AR
1) Update rate for generating the augmented image.
2) Accuracy of the registration of real and virtual image
3) Noise
4) Time delay

16.  AR is relatively new field and is far behind maturity.
 A breakthrough is required in real-time HMD tracking in
outdoors at the accuracy required by AR.
 AR has a great future as it promises better navigation and
interaction with real and virtual world in ways which was
science fiction.
