Topic : How Virtual Reality Work

Virtual reality (VR) is the arrangement of a user interface in 3D as we know that the TV screens and monitors only allow a partial 3D experience. Virtual reality, on the other hand, can provide a 360-degree immersive experience to users. Virtual Reality innovators and developers are constantly working in this domain and increasingly discovering new openings in an immersive medium driven by different approaches and tools. According to a study, it is observed that around 58.9 million people will use VR at least one time every month by the end of the 2021 year. Have you ever wondered how virtual reality work? How it makes you closer to reality, and how do you feel yourself in the picture? Here in this article, you will get the answer to all your questions.

Characteristics of Virtual Reality

Virtual reality usually contains four main characteristics. It includes believable, interactive, immersive, and computer-generated. The believable characteristic makes you feel like you are in your virtual world through what you observe and hear. You feel yourself in the picture through the things that come your way, and you believe in them. Similarly, the interactive characteristic is how a user can interact with different objects, whether opening a door, pressing a button, pushing an object, or more.

On the other hand, the immersive property is the one in which you move your head around. You will see the changes and perceive them as real life-changing. The VR worlds are generally formed with complex 3D computer graphics that transform in real-time as we move, and all this is computer-generated.


Working of Virtual Reality

How does virtual reality works? Well, virtual reality is one of the fastest-growing technologies in the world. It is a source of excitement and thrill for many customers. The complete processing of VR content requires both hardware and software. The software part helps create the environment for users, whereas the hardware is used for screening purposes.

The VR headset conveys another version of reality to you which provides you an opportunity to interact with new environments. As human beings, we stand our insight of the world on the policies and rules developed by our experience. VR designers utilize the fundamental practices of insight and ideasof how we interrelate with the world to produce environments that feel just as real as the world around us.

Overall, VR means forming a simulation of a real-world practice that a person can penetrate and leave at any time according to their choice using technology. With more development and work in this area, all these simulations are getting more accurate and in-depth. The VR technology also continues to grow cheaper, conveying VR to a place where almost everybody could have the possibility to try it.

Important Components of VR Evolution

VR headsets are just machines. These are intended to substitute our surroundings with something shaped in software. There are accelerators, magnetometers, and gyroscopic sensors in headsets to decide how you stir and trail your interactions with a virtual space. One can also connect their headset to computer systems and external cameras to access software for a VR experience. Presently, the most impressive VR experiences are assembled on the following functionalities.

Field of View

It has been a general apprehension for VR developers. For VR to submerge us in new surroundings, it needs to imitate our field of view. Unluckily, human beings are competent of a lot wider area of sight in common than headsets can usually provide. The average human can perceive around 220-degrees of nearby content. A VR headset can carry out around 180 degrees. The field of view in the headset speaks the world you perceive around you and how much it imitates your current setting.

Frame Rate

Dealing with the frame rates in virtual environments is not an easy job to perform. The reason is that there is no actual technical consensus on how responsive human vision is in that regard, as we all know that human eyes can see up to the counterpart of 1000 frames per second. According to a study, it is observed that humans can distinguish frame rates up to 150 FPS, but away from that, the information is mislaid in translation on the way to the brain.

Most VR developers have found that something less than 60 FPS tends to source headaches, nausea, and disorientation in the user. Most of the VR hardware developers nowadays are going to begin pushing for a frame pace of 120 FPS or more, which provides a more realistic experience to users.


It is another important technological aspect of VR technology. The designers make use of sound effects to transmit a sagacity of three-dimensional space to the customer. Nowadays, cutting-edge VR relies on spatial audio technology to produce a simulated audio setting that matches the visuals formed by VR. The improved the audio, the more engrossed you feel. The sound effects seem to come from above, to the side, or behind you.

There are a large number of current implementations, but they all contribute to some comparable characteristics. It includes volume control, working reverberation to imitate environmental factors, using left/right setback to transmit direction, using head trails to map hearing space, and more. It is also essential to keep in mind that the audio effects explained here have to be computed in real-time to the user’s movement for a virtual reality headset.

Position Tracking

The property and feature that makes virtual reality truly engaging allow users to move around in a virtual space and experience things. The position and head tracking features are calculated in degrees of freedom, allowing the consumer to discover either 3 degrees of freedom or 6. Headsets with 6 degrees of freedom provide a complete autonomous movement through space to users. Sensors that are present outside of the VR receiver can also assist the user in staying safe while moving around in a room.

The tracking technology for VR is mounting more impressive. The eye-tracking technology present in it can help users improve their focus in VR experiences and decrease the sense of nausea that some people have while functioning within a headset. Similarly, the haptic feedback sensors present in it and other tracking technologies can make the scene feel more immersive.

VR headsets

Different types of VR headsets are available in the market nowadays. Here in this section, you will get to know about other headsets. Users can select the one according to their choice and preference.

Mobile VR headsets

The mobile headsets are shells amid lenses into which one can easily place their smartphone. These lenses split the screen into two images for your eyes, making your smartphone a virtual reality device. The mobile headsets are relatively low-priced. All the processing is managed on your smartphone. There is no need to attach any wires to the headset to enjoy the VR experience.

However, keep in mind that smartphones are not intended exclusively for VR. Such devices cannot offer the best visual experience to users. These are also underpowered as compared to some game console-based VR or PC. Moreover, mobile VR cannot provide positional tracking to users. One can look around the surroundings from a sole point but is unable to look around objects.

Standalone headsets

The standalone headsets allow users to enjoy high-quality VR anywhere at any time without using cables, PC, or phones. This all-in-one virtual reality headset is popular among people because of its usage and amazing content quality. These standalone headsets are wireless. It is simple to use. One can quickly bring it with them everywhere they go. This single incorporated piece of hardware works similar to a tablet or phone.

PC based VR headsets

The PC headsets give a more immersive experience to users at an elevated price point. These headsets are usually tethered with cables from the headset to an exterior hardware part to control the headset.

The keen display, built-in motion sensors, and exterior camera tracker improve both sound quality and image. It provides an excellent head tracking experience to users.

The Future of VR Technology

Virtual reality technology is rising increasingly impressive. The VR developers explore different ways to make the virtual world feel more like the actual world. With more advancement in this area, the headsets become more mobile and sleeker, with fewer wires and additional high-definition pixels. Similarly, the tracking gloves and haptic sensors are also replacing clunky control systems. The AI advancements and machine learning also alter the approach that VR technology tracks our interactions.

We can anticipate seeing a lot more pioneering uses for the technology in the coming time as we set up for an entirely new virtual globe of information and communication, entertainment, as developers, games designers, engineers, and film-makers are keep on investigating the VR medium and its new imaginative potential with each passing day.
