Augmented Reality (AR) enhances the real world by overlaying computer-generated sensory inputs like graphics and sounds, creating an enriched perception of reality. In contrast, Virtual Reality (VR) immerses users in a completely simulated environment, detaching them from the real world. AR applications range from entertainment and education to military training, utilizing various devices such as smartphones, laptops, and head-mounted displays.

1. AugmentedReality
Linking Real and Virtual Worlds

2. What is Augmented Reality or AR ?
A live direct or indirect view of a physical, real-world
environment whose elements are augmented by
computer-generated sensory input, such as sound or
graphics or GPS. As a result, the technology functions
by enhancing one’s current perception of reality.

3. What is Augmented Reality or AR ?
• AR can maintain the high-level of detail and realistic shading
that one finds in the real world.
• 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.

4. What is Virtual Reality or VR???
Computer-simulated environments that can simulate physical
presence in places in the real world, as well as in imaginary
worlds.
Virtual reality replaces the real world with a simulated one.

5. AR vs VR
VR: the user is completely immersed in an artificial world and becomes divorced
from the real environment. The generated world consists entirely of computer
graphics.
an AR system is augmenting the real world sense of presence in that world. The
virtual images are merged with the real view to create the augmented display.
A main motivation for the use of AR relates to the computational resources
necessary to generate and update computer-generated scene. In VR, The more
complex the scene, the more computational resource needed to render the scene.

6. Type Of AR
Monitor Based
Laptops
Cell phones
Projectors (more Ubiquitous Computing)
Head Mounted Displays:
Video see-through
Optical see-through

7. Monitor Based AR• Simplest available
• Treat laptop/PDA/ cell
phone as a window through
which you can see AR world.
• Sunglasses demo

8. Optical see-through HMD

9. Video see-through HMD

10. Head Mounted
Displays
GOOGLE Glasses

11. Artificial Landmark Based AR

12. Applications of AR
Entertainment
Weather report
Virtual studio
Movie special
effect

Presentations
Can now be more interactive

13. •Video Games
•Physical interactions with 3D models
•Television
•You will be able to watch TV in 3D any where

21. The military has been using display in
cockpits that present information to
the pilot on the windshield of the
cockpit or the visor of their flight
helmet. This is a form fo AR display.
Military Training
