Virtual
Reality (VR) is generally defined as a three-dimensional computer-generated
world that can be explored interactively through a variety of computer
peripheral devices. Virtual reality (VR) can also refer to a computer-simulated environment that can
simulate physical presence in places in the real world or imagined worlds. Most
current virtual reality environments are primarily visual experiences,
displayed either on a computer screen or through special stereoscopic
displays, but some simulations include additional sensory
information, such as sound through speakers or headphones. VR systems are configured
to display the computer-generated world, or virtual environment, so that the
image changes continuously depending upon the orientation and gaze of the user.
Nowadays, human senses have allowed the interaction between human and VR
technologies. These VR technologies have many usages in some specific area like
in health, education and so on.
Health and Medical
These VR technologies can be use in health, it can also
be use as a medical tool. Healthcare is one of the biggest adopters of virtual reality which
encompasses surgery simulation, phobia treatment, robotic surgery and skills
training. One of the advantages of this technology is that it allows healthcare
professionals to learn new skills as well as refreshing existing ones in a safe
environment. Plus it allows this without causing any danger to the patients. Virtual
reality is quickly finding wide acceptance in the medical community as
researchers and clinicians become aware of its potential benefits. In the
United States, significant public dollars have been invested in the research
and development of VR technologies, especially by the military which views VR
as a promising tool for both training and physical and psychosocial rehabilitation.
Revolutionary health care applications have been studied for surgical
procedures (e.g., remote surgery), medical therapy, preventive medicine,
visualization of databases, skill enhancement and rehabilitation, and medical
education and training. VR has also been shown to be highly effective as a
psychotherapeutic tool. It is often used to distract patients during painful
medical procedures or to provide graded exposure during treatment for a wider
range of anxiety disorders including posttraumatic stress disorder. VR can
provide a blend of both distraction and experiential therapies that teach
patients these techniques within a structured, safe environment. Virtual
reality is often used as a diagnostic tool in that it enables doctors to arrive
at a diagnosis in conjunction with other methods such as MRI scans. This
removes the need for invasive procedures or surgery. Below is the example video of using VR to make surgery :

Besides,
VR technologies can also be use in education. Education is another area which
has adopted virtual reality for
teaching and learning situations. The advantage of this is that it enables
large groups of students to interact with each other as well as within a three
dimensional environment. It is able to present complex data in an accessible
way to students which is both fun and easy to learn. Plus these students can
interact with the objects in that environment in order to discover more about
them. For example, astronomy students can learn about the solar system and how
it works by physical engagement with the objects within. They can move planets,
see around stars and track the progress of a comet. This also enables them to
see how abstract concepts work in a three dimensional environment which makes
them easier to understand and retain. This is useful for students who have a
particular learning style, e.g. creative or those who find it easier to learn
using symbols, colours and textures. VR can also use in education like to train teachers before they teach their students. --> Virtual Reality Classroom Trains Teachers
In conclusion, these types of
studies may also be useful to explore related concepts which rely on the
quality of information that is remembered and/or perceived within a virtual
environment. The qualities of memories are also important in training in or
learning from virtual environments. Since the Virtual Reality Monitoring
decision process defines a measure of "realism" for a virtual
reality, it can be correlated with transfer-of-training measures in order to
determine if learning benefits from the degree of realism of the simulation.
