Virtual reality involves immersing users in simulated, 3D environments through specialized headsets or displays. It has emerged as an important technology with applications in many fields. Virtual reality can be immersive, where users are fully immersed in a simulated world, or non-immersive where users view simulated content but remain aware they are not physically present. It has seen increasing commercial development and uses since the 1980s. Today, virtual reality is used for applications such as education, training, gaming, engineering design, and healthcare. While it allows for new experiences, virtual reality also has disadvantages including high equipment costs and limitations on physical interaction compared to the real world.

2. Virtual reality
 Virtual reality means feeling the imaginary world
rather than the real one. The imaginary world is
the simulation running in the computer.
 Virtual reality is the term used for the computer
generated 3D environment that allow the user to
enter and interact with the alternate realities.
 The definition of virtual is ‘Near’ and ‘reality’ is
what we experiencing as humans

3. Data
&content
Context
• Context I created or re-created ,
presented with in a dedicated
headset or special smart phone
viewer
• Data and content are presented at
the same time.

4. History of Virtual Reality
• More than one person has been
involved in the development of this
technological system.
• In 1950’s Visionary cinematographer
Morton Heilig built a single user
console called sensaroma.

5. • In 1961, Philco corporate engineers
developed the first HMD known as
Head sight
• In 1965 Ivan Sutherland
Envisioned what he called the
ultimate display.
• In 1988 commercial development
of VR begun.
• In 1991, first commercial VR
system
• “virtuality” was released.

6. Types of Virtual Reality
1.Immersive Virtual reality( see simulated world and be in
the simulated world)
2.Non Immersive Virtual reality (see information about real
world presented via computer-Location based services)
3.Augmented reality (stay in real world but see simulated
objects)

7. IMMERSIVE VIRTUAL
REALITY
• Immersive virtual reality means is a perception of
being physically present in a non physical world.
• Elements of Virtual environment that increases the
immersions of the experience.
1. Continuity of surroundings
2. Conformance to human vision
3. Freedom of movement
4. Physical Interaction
5. Feed back

8. NON IMMERSIVE VIRTUAL REALITY
Large display but does not surround the user

9. Augmented Reality
Stay in real world but see stimulated objects
Eg: HMD

10. APPLICATIONS OF VIRTUAL
REALITY

11. BUSINESS
• Virtual tours of a business environment.
• Training of new employees
• A 360 view of product

12. Engineering and Design
• It is widely used in Engineering and design
process
• It gives better understanding of the design
and facilitates changes where ever necessary.
• It helps to reduce the time and cost factor.
Example: Car designing ,Building designing

13. Medical
 Health care is one of the biggest
adopters of virtual reality which
encompasses surgery simulation
phobia treatment, Robotic surgery and
skills training.
 VR find its application in nursery,
dentistry, health issues for the
disabled.

14. Entertainment
• Virtual Museum
• Gaming
• Virtual theme parks

15. Education
Learning through experience

16. Learning through reflection

17. Learning through Creation

18. Learning through collaboration

19. Device Used in Virtual Reality
Head mounted display Cave automatic Virtual Environment

20. Data gloves

21. 3D Audio
Data Suit

22. • Virtual reality creates realistic world.
• It enables user to explore places
• Through virtual reality user can
experiment with an artificial
environment.
• Virtual reality makes the education
more easy and comfort
• The equipment's used in virtual
reality are more expensive.
• It consist of complex technology
• In virtual reality environment we
cant move like our own like in the
real world.
Advantages Disadvantages
