DESCRIPTION
Virtual Reality is a way to submerged into the imaginary world even being in real world. The two words contrast each other. Here we combine virtual which mean imaginary and reality which means something which actually exist. Hence virtual reality signifies making the imaginary things to seem as they are in real world

VIRTUAL REALITY
Virtual reality is computer generated multi-sensory
information program which tracks a user in real time.
It is a technology which allow user to visualize,
manipulate and interact with a computer
simulated environment.
Virtual reality is, plainly speaking, Seeing, hearing, smelling,
testing, feeling an imaginary world, rather than the real
one. The imaginary world is a simulation running in a
computer. The sense data is fed by some system to our
brain.

NON IMMERSIVE SYSTEM
It is “through the window” system.
It involves displaying virtual world on a screen without surrounding
the user.
Augmented realityAugmented reality (AR) is a term for a
live direct or an indirect view of a
physical, real-world environment whose
elements are augmented by computer-
generated sensory input, such as sound
or graphics, haptic feedback.
User Stay in real world, but
see simulated objects
IMMERSIVE SYSTEM
A type of VR in which the user
becomes immersed (deeply
involved) in a virtual world.
The CAVE (Cave Automatic
Virtual Environment) provides
the illusion of immersion by
projecting stereo images on
the walls and floor of a room-
sized cube.
User See simulated world and
"be" in that simulated world.
Practice performing
surgery.
Perform surgery on a
remote patient.
Teach new skills in a
safe, controlled
environment
MEDICINE
• Driving simulators
• Flight simulators
• Ship simulators
• Tank simulators
EDUCATION AND TRAINING
• Designers can interactively test a building before construction begins.
• Allow designers and clients to examine homes and office buildings, inside and out, before they're built.

ADVANTAGES
DISADVANTAGES
VR replacing reality. Disengagement with real world. People preferring VR to reality. Difficulty of distinguishing between virtual and real, ‘false realities represented in
VR. Lack of standardization of hardware and protocols Possible impacts on real body
FUTURE
●1999 10% of the world's computing power was
non-human
●2029 99% of the world's computing capacity
will be non-human
we should have computers powerful enough to run immersive VR programs in every home by the year 2037.
