I’m quite sure you must have boggled listening to the concept called virtual reality when you heard it for the first time. I mean, ‘virtual’ and ‘real.’ They are simply antonyms. You would think how is it possible that it becomes a single term? Yes! The advancements in visual technology and video creation tools have made it possible to set up anything virtual that feels to be real! Simply talking, virtual reality is a computer generated replica of three-dimensional picture or ambiance that you can interact apparently with real or physical manner using an individual electronic device. For example, imagine that you are wearing a helmet inside which a small screen is fitted to your eye level to give you a feel as if you are driving a bike. Or, you might be provided with gloves having sensors that vibrate. 

Virtual reality is surpassingly becoming popular among the users day by day. The reason behind, it rightly puts a user into the artificially created environment to offer a complete experience of the situation. Hence, it highly enriches the user interface and user experience. As mentioned above, a simulation may take place in any form of touch, feel, vision or hearing. In VR technology, a computer uses many sensors and computing functions. It is set up in such a way that user’s eyes are located within the simulated environment. For example, if user bows head, graphics operate accordingly. The world created by virtual reality is indeed fascinating and convincing to the audiences. 

Now let’s explore a bit about technological aspects of the virtual reality. The most visible and obvious factor you could identify in virtual reality is a head mounted display. We all are optical souls and believe in what we see. Conventional user interface and enveloping virtual reality are exactly opposite to each other. Nowadays,  some hardware and software choices are available in the global markets to make efficient use of virtual reality. Several brands are competing to create new levels of visual entertainment and interaction. VR is user-friendly and convenient technology to be used for diversified purposes. All you need to do is to purchase or hire a helmet sized device that can be utilized on shop floors, living rooms, open grounds, workplaces and so on. 

One more important aspect I would like to include is audio systems and formats. Humans react more quickly to audio indications than visual happenings. Believe it or not! Right audio signals is a requisite to experience practical virtual reality. Ambiance and dimensional sounds together create exemplary impact If you get a clear sound, VR that you are going to feel is realistic than ever before! Since all types of audiovisual data can be transformed into virtual reality, research and development are a continuous activity that brings surprises to us. 

In context to market applicability, many major corporate organizations are investing and constructing VR devices, platforms to sustain in the competitive environment. These companies are making correct use of virtual reality for promotional and marketing activities of their products and services. In today’s world, corporate and customers communication has changed with inventions such as virtual reality and 360-degree coverage. Corporate companies have used virtual reality for arranging e-learning programs to offer a combined experience of theory and practical. VR is ideal for different learning programs as it simplifies critical problems. While using VR, there is no requirement of repeated prototyping, and a single model is typically set up to use it for all types of applications. Also, these systems can be accessed remotely from multiple locations. Over and above, cost-effectiveness and easy executions of VR techniques are like a cherry on top of it. 

Challenges faced in VR technology include better tracking systems, more natural processes to interact with a user to provide him with the most existent experience,  time taken to create the virtual environment and so on. However, faster upgrades in devices and practices have been successfully dealing with the above-listed hurdles resulting in the refinement of VR day by day.
