"Virtual reality" is a "reality" that is created within
the constructs of a computer. It has no basis in actual
physical constructs.
Virtual reality (VR) is a computer-generated
three-dimensional environment that generally provides real-time interactivity for the
user.
Also...
Virtual reality (VR) is a term that applies
to computer-simulated environments that can simulate [mimic, replicate] physical
presence in places in the real world, as well as in imaginary
worlds.
In virtual reality,

created. Some are very basic, whereas others may be extremely sophisticated and complex.
Virtual reality has been in place since the mid-1990s, but still has quite a distance to
go before it is utilized to its greatest potential. The gaming world has moved into
using virtual reality. The business and manufacturing arenas have also experienced some
success using virtual reality in employee training, product design and areas of
management development.
For business uses, some successful applications
of VR have been in such areas as product design and modeling, employee training, data
visualization, and management decision-making
aids.
"Transportation
equipment design" has also benefitted from using virtual reality in providing design
input that will ultimately be of benefit to the driver, especially in the area of
safety; changes can be made in the virtual world without great expense, saving
automotive manufacturers a great deal of money.
For example, automotive designers can use a
simulation of proposed car design to pretest usability concerns like the driver's range
of view through the windshield, the impact of glare on the windshield, how well the
headlight design functions in different driving conditions, and a host of other design
factors. If the simulation shows unfavorable results, the design can be changed at a
relatively low cost compared to finding these problems only after a physical prototype
is made.
