Virtual reality is a computer-simulated environment that can recreate sensory experiences like sight, sound, and touch. The history of VR began in the 1960s and has since been used in various fields like education, medicine, business, and the military. While VR offers many applications, it also faces challenges in causing simulation sickness and disorientation when users cannot see the real world. As the technology advances, VR is expected to become more integrated into daily life and human activities.

2. INTRODUCTION
 Virtual reality is a form of technology which creates
computer generated worlds or immersive
environments which people can explore and in
many cases, interact with.
 Virtual reality (VR), sometimes referred to
as immersive multimedia, is a computer-
simulated environment that can simulate physical
presence in places in the real world or imagined
worlds. Virtual reality could recreate sensory
experiences, including virtual taste, sight, smell,
sound, touch, etc.

4. IMPACT
 There has been an increase in interest in the potential social
impact of new technologies, such as virtual reality. Bailenson
review the literature on the psychology and sociology behind
life in virtual reality
 Virtual reality will be integrated into daily life and activity,
and will be used in various human ways. Another such
speculation has been written up on how to reach ultimate
happiness via virtual reality.
 Techniques will be developed to influence human
behaviour, interpersonal communication, and cognition.
 As we spend more and more time in virtual space, there will be
a gradual "migration to virtual space", resulting in important
changes in economics, worldview, and culture.

8. IMPLEMANTATION
To develop a real time virtual environment, a computer graphics library
can be used as embedded resource coupled with a common programming
language, such as C++, Perl,Java, or Python. Some of the most popular
computer graphic libraries are OpenGL, Direct3D, Java 3D, and VRML.
 Urban design
3D virtual reality is becoming widely used for urban regeneration
and planning and transport projects. In 2007 development began on a
virtual reality software which took design coordinate geometry used by
land surveyors and civil engineers and incorporated precision
spatial information created automatically by the lines and
curves typically shown
on subdivision plats and
land surveying plans.

9. Manufacturing
Virtual reality can serve to new product design, helping as an ancillary
tool for engineering in manufacturing processes, new product prototypes,
and simulation. Among other examples, electronic design
automation, CAD, Finite Element Analysis, and computer-aided
manufacturing are widely utilized programs. The use of Stereo
lithography and 3D printing shows how computer graphic modelling can
be applied to create physical parts of real objects used
in naval, aerospace, and automotive industries, which can be seen, for
example, in the VR laboratory of VW in Mladá Boleslav.

10. CONCERNS & CHALLENGES
Virtual reality technology faces a number of
challenges, most of which involve technical matters
and Simulation sickness due to virtual reality .
Users might become disoriented in a purely 'virtual'
environment, causing balance issues; computer
latency might affect the simulation, providing a less-
than-satisfactory end-user experience; the
complicated nature of head-mounted displays and
input systems such as specialized gloves and boots
may require specialized training to operate, and
navigating the 'real' environment might prove
dangerous without 'external' sensory information.
