Augmented reality (AR) uses computer-generated graphics overlaid on real-world environments, enhancing users' perceptions of and interactions with the real world. AR aims to make virtual elements seem part of the real scene by using displays like mobile phones or head-mounted devices. Examples include enhancing sports broadcasts with statistical overlays or assisting with industrial design processes. AR has applications in entertainment, military training, manufacturing, and more.

1. AUGMENTED REALITY

2. 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.
• The sensory inputs can be sounds or graphics.
• Augmented Reality is a type of virtual reality that aims to duplicate the world's
environment in a computer.
• It is a layer of virtual elements on the real world.

3. Goal:
“Create a system such that a user cannot tell the difference between the real world
and the virtual augmentation of it.”
“To enhance a person’s performance and perception of the world”

4. Examples:
Lbw decisions, spider diagrams, ball trajectories, etc. in cricket
is a very basic example

7. How AR works?
• Pick A Real World Scene
• Add your Virtual Objects in it.
• Delete Real World Objects

8. Available Display Devices In AR
• Head-mounted Display(HMD)
• Eye Glasses

9. • Handheld
• Spatial

10. Display Devices Under Development
• Contact Lenses
• Virtual Retina Display

11. Display Technologies
• Monitor Based
1. Laptops
2. Cell phones
3. Projectors
• Head Mounted Displays:
1. Video see-through
2. Optical see-through

12. Monitor Based Augmented Reality
• Simplest available
• Treat laptop/cell phone as a window through which you can see AR world.

13. Example:

15. Optical see-through HMD

16. Example:

17. Video see-through HMD

18. Example:

19. Augmented Reality is used in:
• Entertainment
• Military training
• Engineering design
• Manufacturing and other industries
• Engineering Design
• Robotics and Tele-Robotics

20. Conclusion
“Augmented reality (AR) is a way of delivering entertainment media that uses
computer generated graphics transposed over real-life scenes.”
