This document covers augmented reality (AR) and virtual reality (VR). It defines AR as technology that superimposes digital images onto the real world, typically through a device, while VR immerses users in a simulated digital environment using headsets. The document discusses how each works, providing examples of AR apps. It outlines advantages like enhanced experiences for AR and exploring places for VR. However, both rely on technology, posing issues like battery drain and privacy concerns for AR or implementation costs for VR. The document concludes by listing VR applications in fields like military, sports, and medicine.

4. What is Augmented Reality ?
Augmented Reality (AR) is a technology that superimposes computer-generated images, videos, or information onto the
real world, typically viewed through a device such as a smartphone, tablet, or AR headset.

5. How does Augmented Reality Works?
1. Seeing the World: AR devices use cameras and
sensors to see the real world.
2. Understanding What's There: They recognize
walls, floors, objects, and people.
3. Adding Digital Magic: Once they understand the
surroundings, they overlay digital images, videos,
or information.
4. Making it Interactive: Users can interact with the
digital content, like tapping or moving it.
5. Updating as You Move: The device updates the
digital content as you move around, so it stays
connected with the real world.

7. EXAMPLE
1.Snapchat Filters: Add fun effects to your selfies and photos.
2.IKEA Place: See how IKEA furniture looks in your home
before buying.
3.Google Maps AR Navigation: Get directions with virtual
arrows overlaid on the real world.

9. Advantages of Augmented
Reality
1. Enhanced Experience.
2. AR will be Easy to Use.
3. Supports Business
Activities.
4.Educational Advantages of
Augmented Reality.

10. Disadvantages of Augmented Reality
•Dependency on Technology: Relies on specialized devices, leading to dependency and
potential costs.
•Battery Life and Performance: Drains device battery and may impact performance.
•Technical Limitations: May face issues like limited field of view and tracking inaccuracies.
•Privacy Concerns: Raises privacy risks due to data capture and process

11. What is Virtual Reality?
Virtual Reality (VR) is a technology that immerses users in a simulated digital environment, completely separate
from the real world. It typically involves wearing a VR headset that covers the user's eyes and ears, blocking out the
physical environment and replacing it with a computer-generated one.

12. How Does Virtual Reality Work?
1. Special Glasses: You wear special goggles or a
headset that has screens inside.
2. Tracking Movement: These goggles have sensors
that track your head movements in real-time.
3. Creating a World: A computer creates a whole
new world based on how you move your head.
4. Seeing and Hearing: The screens inside the
goggles show you this world, and sometimes there
are also headphones to hear sounds from the
virtual world.
5. Interacting: You can interact with this virtual
world using controllers or your hands.
6. Feeling Like You're There: When you wear the
goggles and interact with the virtual world, it feels
like you're really inside it, even though you're still
in the real world.

13. • Advantages of Virtual Reality
1.Virtual reality helps in exploring
places without actually being there.
2.It creates a realistic world
3.Increases interest and engagement
toward a subject
4.Help in providing training
5.The education system has been
improved

14. Disadvantages of Virtual Reality
1.Implementation is expensive
2.Only develop technical skills no interaction is there
3.Technology is complex
4.Addiction to Virtual Reality
5.Impact on the real human body
6.Psychological damage

15. Applications of Virtual Reality
• In the military, this technology is used in flight simulators or battlefield
simulations.
• In sports, digital training devices help athletes improve their own
performance and analyze their techniques
• In medicine, VR allows trainee doctors to train surgical techniques.
• In the Entertainment Industry
