What is VR & How It Works

In today’s technological world, Virtual Reality or VR is the current hottest topic of discussion. Don’t worry, it is not a new technology, but also it is not much known by the people. So, for all those who are wondering what VR is? You have come to the right place, and here we are discussing what VR is, how does it work and the reasons to choose VR for your business.

So, let’s talk about what is VR, and how does it work?

What is VR?

In technical terms, VR is described as a 3D, computer-generated environment which can be discovered and communicated with, by an individual. The person will experience a different virtual world or engaged with the environment and complete a series of action.

The technology offers a new user interface which is different from the traditional one, that engages a user towards a three-dimensional digital environment, instead of watching it on a screen. The main target of these computer-generated images and content is to pretend the real presence of an object through senses like hearing, touch and sight.

There are two components which are required by VR technology-

  • Source of Content
  • User Device

Or we can say, software and hardware in further terms. Presently goggles, headsets, special gloves are being used in VR. The tools designs in such a way that it offers realistic, innate, premium images and communication opportunities. The feel of wearing a headset and experience a virtual world is still a new field unfamiliar by people.

But have you imagined how VR is tricking the human mind into observing digital content as a real one? 

Yes! That is not an easy task to perform, and the “engagement” factor is the primary concern which still powers the VR experience from being entertaining. The VR experience, like 360-degree videos and images, VR apps and games, are already presented in the market. There is an adequate choice of headsets as well.

How Virtual Reality Works?

In a virtual reality environment, the user goes through immersion or the feeling of being a part of that digital world. The users can connect with this environment in significant ways.

They can experience technology by numerous devices such as a headset, smartphone, computer, to experience a 3D digital environment. For user interaction, there are multiple options-

Head tracking

The head tracking system in virtual reality technology include headsets which control the movement of a user’s head to angles and sides. The headset contains various tools including a circle of LED’s which is around the headset that enables the outside camera, a gyroscope and an accelerometer.

It also consists of X, Y, Z axis to instructions and movements. With the tools and directions, users will observe the interval between the head movements and an imitation.


A few headsets comprise an ultraviolet controller that trails the direction of a user’s eyes within the virtual environment. The significant advantage of this exclusive technology is that users will get a more pragmatic and innate view of the field.

The Effect of Sound

The sound effect is the most significant factor in VR technology. When sound is sync with the visuals, it will create a mesmerising effect which is very engaging and entertain the users.

By using the headsets or 3D sound effects, the users will experience a different world and remain cheered. But while creating the sound effects, there are specific considerations which requires to be taken about the uniformity between the sound and the graphics.

For instance, if one starts playing soothing music in the background of the action scene movie, it will just let down the user experience.

Motion tracking

Motion tracking takes the VR to new heights; it rises the demand for VR in the market. Without motion tracking the use of VR would be narrow; users will not be able to look and move their headsets around.

There is a concept in VR technology named as 6 degrees of freedom and 3D space which sustains the motion tracking feature.

Significant reasons why companies require a virtual reality experience-

  • To boost tourism, hotels, resorts etc.
  • Use as a sales strategy in the automobile industry
  • Use in marketing research
  • Training of new employees
  • Try-Before-You-Buy Programs


VR technology is the creator of a virtual digital environment which presented in such a unique way that we feel it as if we were a part of that world. The technology has used for both acute and entertainment purposes. Though it is time-consuming and expensive and soon it will become inexpensive and widespread.

We can expect to see the highest demand for VR app development in the coming years. We might witness an ultimate way in which we connect and work, thanks to the opportunities of virtual reality technology. Today, there are many companies which already starts working on this technology
