Virtual world replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact with that world. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell.

Many virtual worlds are designed as multi user environments, allowing multiple users to meet and interact.

Most up-to-date virtual realities are displayed either on a computer screen or with an HD VR special stereoscopic displays, and some simulations include additional sensory information and focus on real sound through speakers or headphones targeted towards VR users.noqqb


Virtual reality also acts as a problem solving device in that it enables us to explore various options as a means of finding an answer to a problem.

For example, an engineering company will use virtual reality to produce a prototype which is then tested and the results fed back to the design team. The advantage of this is that it enables the designers to make alterations to their design but at far less time and cost. This is a preferred option to building a physical prototype which is expensive to build and make changes to: especially if it undergoes several alterations as part of the design process.

The aim is to move beyond standard forms of interaction such as the keyboard and mouse which most people work with on a daily basis. This is seen as an unnatural way of working which forces people to adapt to the demands of the technology rather than the other way around. However a virtual environment does the opposite. It allows someone to fully immerse themselves in a highly visual world which they explore by means of their senses. This natural form of interaction within this world often results in new forms of communication and understanding. (Virtual Reality, 2015)



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 and these students can interact with the objects in that environment in order to discover more about them.

As in real life theory based concept can be very difficult to explain and understand, virtual reality can help. 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.



The usage of VR in a training it allow education/training organisation to conduct training in a virtual environment where they can improve their skills without the consequence of failing the operation, which can result in huge cost, injuries or even death.

VR plays an important role in combat training for the military. It allows the recruits to train under a controlled environment where they are to respond to different types of combat situations. Without actually taking the risks involved.  VR vs old ways of training, tradition ways of training requires a lot more resource to conduct such as physical space, equipment’s etc, whereas VR can reduce amount of resource require for training therefore reduced cost.

VR is also used in flight simulation for the Air Force where people are trained to be pilots. The simulator would sit on top of a hydraulic lift system that reacts to the user inputs and events. When the pilot steer the aircraft, the module would turn and tilt accordingly to provide haptic feedback.


Video games

The use of graphics, sound and input technology in video games can be incorporated into VR. Several Virtual Reality head mounted displays

Several companies are working on a new generation of VR headsets: Oculus Rift is a head-mounted display for gaming purposes developed by Oculus VR and a lot more other similar products.

The Beginning Project is a project of IBM in Japan, and unfortunately, IBM has revealed they have no plans to make it a complete game. The VR experience was conceived as a showcase of their SoftLayer cloud technology, and its cognitive systems.


Architecture / Construction

Virtual reality can be extremely useful in the construction industry, which is often known as having a very high amount of inefficiency and low profit margins. Using a virtual environment, an organization can not only render the resulting structure in 3D but also experience them as they would in the real world. It helps reduce a lot of waste and errors.

An interactive VR model can reduce time wasted and resources constructing  a physical model in order to demonstrate or illustrate a design concept to target / potential clients. After the building is constructed, it allows developers to create a VR model of a space that allows potential buyers or renters to view the space in VR, even if real-life situations  make a physical visiting  not possible such as distance issues.

A lot more other applications
