What is Virtual Reality?

Definition of Virtual Reality:

Virtual Reality, as the name suggests is a combination of two words, “virtual” and “reality”, where ‘virtual’ means close to, and ‘reality’ is a human experience. So, it can be said that the virtual reality is something close to reality or close to a human experience.

In technical terms, virtual reality is a computer-generated three-dimensional environment that is capable of being interacted with by a human being. The interacting or exploring person becomes immersed in the virtual environment and is capable of transforming things or performing actions as if they were really there, in the simulated environment.


As human beings, we are blessed with the five senses of sight, smell, taste, sound and touch. These are the most obvious systems and organs for perception and sense that we easily recognise. The fact that mostly remains neglected is the fact that the human body is designed with multiple other systems to analyse, process, manufacture and store information. The brain is the best example of analysing the environment, processing the information, thinking of the possible reactions, choosing the best possible reaction, formulating escape plans. For these reasons alone, It will not be untrue if it is said that the human’s perception of reality revolves around the senses and brain.

Virtual reality is an artificial environment achieved by software. This environment is engineered in such a way that the user in experience interprets it as a real experience. The environment is perceived as being real in a virtual reality setting with the use of two primary senses, sight and sound. The most common example to name is a 3D image that is perceived a reality upon sight because of its ability to present itself this way.

In a virtual reality system, the vibrations are transmitted accompanied with other sensations towards the user in such a way through a haptic system or game controller that it achieves the status of a reality or real-life experience.

How To Achieve A Virtual Reality Scenario?

Achieving a state of virtual reality is more difficult than is commonly thought of. This is because the human senses and the brain are synchronised to take on complex information and processes so that even if there are slight deviations or errors, it would be easily detectable making the whole effort useless. In order to make every second worthwhile, a perfect or near to perfect combination of software, hardware and sensory synchronisation is required to manage a virtual reality experience and a sense of presence.

It is at this time that a user will feel like the environment he/she is experiencing is where they are and completely immersive.

Applications Of Virtual Reality:

The applications of virtual reality lie mainly in the entertainment industry, 3D films, Video games, architecture, medicine, sports and arts. However, the technology is highly expensive and is made available for real-life scenarios with an element of danger involved. for example; trainee fighter pilots or trainee medical surgeons. Its main use still focuses on entertainment purposes and the experience is becoming ever more advanced as time progresses.
