Virtual reality (VR) refers to computer-generated simulations that immerse users in an artificial 3D environment that can be interacted with. The document provides an overview of VR, discussing its history from early prototypes in the 1950s-60s to modern implementations. It describes different types of VR systems including immersive, augmented, and desktop VR. The hardware components and data flow that enable the VR experience are outlined. Applications of VR in fields like gaming, medicine, aviation, and military training are highlighted. The document suggests VR will continue advancing in the future.

2. Overview
• Introduction
• History
• Types
• Explanation
• Hardware components
• Conceptional Videos
• Future of VR

3. Introduction
Few Questions for Audience:
• So how many you knows about VR?
• What is Reality?
• What does virtual means?

4. Reality?
• If you’re talking about what you
feel, touch, taste, smell is reality then
it is simply electrical signals
interpreted by brain!
• As Mr. Einstein said: “Reality is
merely an illusion”.

5. Virtual
• Well, It is something which not real.
e.g. Virtual Memory.
• And the funny thing is that VIRTUAL is opposite of REALITY.

6. Virtual Reality
• Virtual Reality refers to a high-end user interface that involves real-time
simulation and interactions through multiple sensorial channels.
• In simple words,
Virtual reality is a computer generated world with which the user can interact.
Interaction can vary from looking around to interactively modifying the world.

7. And here’s the Virtual
Reality Device
• It will provide you 4D
environment.
• Build specially to give you
the concept of presence.
• New World of your desire.

8. Now Let’s discuss
some dates:
1950’s visionary cinematographer
Morton H Eilig built a single user
console called Sensorama . This
enabled the user watch television in
three dimensional ways.

9. In 1961, Philco Corporation engineers developed the
first HMD known as the Headsight.

10. It was built in 1965 IVAN SUTHERLAND
envisioned what he called the “Ultimate Display.”

11. Types of VR System
Immersive Virtual Reality
Augmented Virtual Reality
Desktop (Window on a World) Virtual Reality
Video Mapping Virtual Reality

12. Augmented
VR
• AR integrate the
computer-generated
virtual objects into the
physical world.
• This involves literally
augmenting reality with
virtual information.
• Eg. Pokemon Go game.

13. DESKTOP
VR
• Desktop-based virtual
reality involves displaying
a 3-dimensional virtual
world on a
regular desktop
display without use of any
specialized movement-
tracking equipment.
• Modern computer
games can be used as an
example

14. Video
Mapping VR
• The user watches a
monitor that shows his
body's interaction with
the world.
• The element of
interaction depends on a
number of factors like
speed, range and mapping.

15. Data Flow

16. Components of Oculus Rift VR Headset

17. How we get 3D View

18. Future Of Virtual Reality

19. VR in Military
• For Soldier training.

20. VR in Gaming
• VR is widely used in Gaming giving you a sense
of “Presence”.
• Here are few VR games.

21. Brain Activity

22. VR in Medical Science

23. VR in Aviation
Technologies
• Widely beneficial in
Aviation technology.
