3. WHAT IS VIRTUAL REALITY?
 Virtual Reality(VR), also known as Immersive
Multimedia or Computer-Simulated Reality, is a
computer technology that replicates an environment, real
or imagined, and simulates a user's physical presence and
environment in a way that allows the user to interact with
it.
 Virtual realities artificially create sensory experience,
which can include sight, touch, hearing, and smell.

4. BRIEF HISTORY
Sensorama
• By MORTON
HEILIG in
1950’s.
• 3-D
television
HMD
• By IVAN
SUTHERLA
ND in 1968
• Known as
“The
Sword Of
Damocles”
In 1985
commercial
development
of VR began,
by VPL
RESEARCH.
In 1991, 1st
commercial
entertainmen
t system
VIRTUALIT
Y was
released.

5. FEATURES OF VIRTUAL REALITY
 Believable
 Interactive
 Computer-generated
 Explorable
 Immersive

6. VIRTUAL REALITY SYSTEMS
VR Systems can be divided into three groups:
 Non-immersive systems (like workstations)
See information about the real world, presented via computer - location
based services, GIS .
 Augmented reality systems (like HMD)
Stay in real world, but see simulated objects.
 Immersive systems (like CAVE)
See simulated world and "be" in that simulated world.

7. NON-IMMERSIVE SYSTEM
 “through the windows”
 Large display, but doesn’t surround the user.
Examples:- LCD’s, Play stations, Desktops.

8. AUGMENTED REALITY
 Augmented reality is closer to real world. It add
graphics, sounds and smell to the natural world, as it
exists.

9. IMMERSIVE SYSTEM
 In this system, the user get involved with the virtual
world.

12. APPLICATIONS OF VIRTUAL REALITY
Business:
 Virtual tours of a business environment.
 Training of new employees.
 A 360° view of a product.
Training
 Virtual reality environments have been used for training
simulators.
 Examples include flight simulators, battlefield simulators
for soldiers, paratrooping etc.

13. APPLICATIONS OF VIRTUAL REALITY
Engineering and Design:
 It gives better understanding of the design and facilitates
changes wherever necessary
 It helps to reduce the time and cost factor.
 Examples: Building construction, car designing.

14. APPLICATIONS OF VIRTUAL REALITY
Medical
 Healthcare encompasses surgery simulation, phobia treatment,
robotic surgery and skills training.
Entertainment
 The entertainment industry is one of the most enthusiastic
advocates of virtual reality, most noticeably in games and virtual
worlds.
 Virtual Museum, e.g. interactive exhibitions.
 Virtual theme parks.

15. CONCERNS AND CHALLENGES
 Health and safety
Most virtual reality systems come with consumer warnings, including: seizures,
developmental issues in children, trip-and-fall and collision warnings, discomfort,
repetitive stress injury, and interference with medical devices.
 Privacy
The persistent tracking required by all VR systems makes the technology particularly
useful for, and vulnerable to, mass surveillance. The expansion of VR will increase
the potential and reduce the costs for information gathering of personal actions,
movements and responses.
 Conceptual and philosophical concerns
As we spend more and more time in virtual space, there could be a gradual "migration
to virtual space", resulting in important changes in economics, worldview, and
culture.
