WHY VIRTUAL REALITY ENVIRONMENT ?


VR

serves

as

a

cost
-
effective

problem
-
solving

tool
.

In

Virtual

Reality

(VR),

human

computer

interface

technology

leverages

the

natural

human

capabilities
.



Today's

interfaces

(keyboard,

mouse,

monitor,

etc
.
)

force

us

to

working

within

tight,

unnatural,

two
-
dimensional

constraints
.


VR

provides

engineers

with

real

audio,

visual

&

sensory

perception

in

a

more

intuitive

&

natural

manner
.





VR system lets the engineer experience data directly.







In

VR
,

engineers

can

look

and

move

around/inside

a

virtual

model

or

environment,

drive

through

it,

lift

items,

hear

things

&

feel

things
.

MISSION OF VIRTUAL REALITY LABORATORY
