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.

BRIEF HISTORY

Sensorama

• By MORTON HEILIG in 1950’s.

• 3-D television

HMD

• By IVAN SUTHERLAND in 1968

• Known as “The Sword Of Damocles”

In 1985 commercial development of VR began, by VPL RESEARCH.

In 1991, 1st

commercial entertainment system VIRTUALITY was released.

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.

NON-IMMERSIVE SYSTEM

“through the windows”

Large display, but doesn’t surround the user.

Examples:- LCD’s, Play stations, Desktops.

AUGMENTED REALITY

Augmented reality is closer to real world. It add

graphics, sounds and smell to the natural world, as it

exists.

IMMERSIVE SYSTEM

In this system, the user get involved with the virtual

world.

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.

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.

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.

CONCERNS AND CHALLENGES

Health and safetyMost 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.

PrivacyThe 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 concernsAs 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.
