What is virtual Reality(VR)?

When virtual reality was first predicted a few years ago, it was nothing more than a dream. It is therefore not surprising that it has now become a reality.

Computers essentially can create a virtual environment that allows people to share information and communicate with each other in a believable setting.

Consequently, virtual reality allows us to experience a different world without having to move or change our location.

In recent years, virtual reality has become one of the most popular technologies. This article will discuss this new technology, its functions, purposes, and what applications we can utilize to take advantage of it.

What is virtual reality (VR)?

Virtual reality

With the use of computer technologies, we can simulate different environments in a virtual world that does not exist in the real world. Virtual means to simulate different environments based on data that does not exist in the real world.

An individual in the virtual world engages in interactions with objects and individuals as if they were completely immersed in a virtual environment, communicating with them as if they were in the real world.

The use of virtual reality is one of the most innovative technologies in the world, and as such it has the potential to truly revolutionize how we interact with the world around us, as well as turn computers into vehicles to travel around the world, eliminating geographical barriers. The only limitation is the system’s processing power and access to information.

In recent days, we have seen a significant increase in the production of headsets that can provide virtual reality experiences, and these headsets can be used for an array of different purposes.

A wide range of stakeholders, including developers, government officials, and local authorities, are increasingly utilizing Augmented Reality technology for urban planning and sustainable development.

In the current state, AR is not required to use a headset, and it will become more accessible as time goes on. We are currently working on creating AR and VR headsets that can work together.

Types of virtual reality

Fully Immersive Simulation

Floating virtual reality can provide an entirely immersive experience in which the user does not realize that the device is not real. This type of virtual reality is typically used for entertainment settings and games, which require a powerful computer to make it work.

Virtual reality headsets, the game handles, and sometimes special VR clothes are used to track the user’s input. Their movements are tracked and processed to determine the user’s input.

Although there are still many issues to be resolved in this area, one of the best games in this field is Half Lafie Alyx. Additionally, VR Chat, a very popular application, uses this technology as well.

Semi Immersive Simulation

In the past, this type of virtual reality headset has been used to train and educate people in simulation. For example, you can train as a pilot while wearing a semi-floating virtual reality headset.

It is essential to have the hardware, such as a large screen, as well as accessories, such as headphones and joysticks, to deliver a semi-immersive virtual reality experience. Although virtual reality simulates the world, it differs from reality in certain important ways.

Non-Immersive Simulation

Although there are many types of virtual reality, this one is often overlooked due to its widespread use in everyday life, as it allows the user to interact with both a physical and virtual environment, such as a virtual environment within a video game.

Non-floating virtual reality technology is a virtual computer environment in which the user is simultaneously aware of and controlled by his physical environment. Video games are a prime example of non-floating virtual reality.

How does virtual reality technology work?

We now turn our attention to how VR technology works. As we said previously, this technology utilizes hardware and software tools to enable users to immerse themselves in a virtual environment. Since this occurs in such a realistic manner, it can be difficult to distinguish between a virtual and a real environment.

What hardware does virtual reality use?

virtual reality hardware

To use the capabilities of VR-based systems, we need special hardware and tools. The most useful tools available for virtual reality experience are:

  • Virtual reality headsets
  • A powerful PC
  • Virtual reality gloves
  • Virtual reality handheld controllers
  • VR accessories

Virtual reality headsets

In order to get the most out of your virtual reality experience, you will need a powerful headset. The quality and features of the headset can greatly enhance your virtual reality experience. There are two best virtual reality headsets for the PC, the Oculus Rift, and the HTC Vive.

In general, VR headsets range between 250 and 450 dollars, depending on what features they include and what accessories they require. Other headset brands are available, but these two are among the most excellent, so you should use them as much as possible.

A powerful PC

It is recommended that you have at least a powerful PC with a graphics card that has a minimum of NVIDIA GTX 1050 Ti or AMD Radeon RX 470 for the two headsets listed above in order to enjoy virtual reality.

If you wish to achieve the best results, we recommend choosing a computer with at least a Core i3-6100 CPU or AMD Ryzen 3-1200, as well as a RAM of at least 8GB. However, this minimum experience will not give you the best results, so we recommend choosing a computer with 1080 graphics and a Core I7 processor, along with 16GB of RAM.

Cheaper ways

I propose two other ways to experience virtual reality The first way is by using the PlayStation 4 console with the PlayStation VR headset. Your only cost is the PlayStation VR headset, and you can enjoy VR games on this console.

In fact, we now have a cheaper option for Android phones and virtual reality headsets for smartphones, which are both available online at a variety of price points. All you need to do is select one of the hundreds of virtual reality headsets for smartphones and begin your journey.

Even though smartphones offer a less immersive virtual reality experience than desktops and laptops, it is still a worthwhile experience that I encourage everyone to try.

Virtual reality gloves

Special gloves are one of the most advanced handheld devices available today. They have been designed to track the movements of the hand and to simulate sensations such as vibration and heat so that the user can feel like they’re in real life by using virtual reality technology.

Virtual reality handheld controllers

In this tool related to virtual reality technology, the user is able to interact with virtual objects and components as well as adjust the position of their hand in relation to virtual objects in virtual reality.

As well as the ability to perform functions such as holding or releasing an object, the tool also allows for the user to perform tasks such as controlling the level of intensity in VR.

VR accessories

VR accessories are becoming increasingly popular as technology advances in order to create an immersive experience. There are a variety of current VR accessories available today, including:

  • 3D mouse
  • Optical detectors
  • Wire gloves
  • Dress
  • Treadmills
  • Olfactory devices

What software does virtual reality use?

Developers use a variety of software, including visualization kits, content management, game engines, social platforms, and educational simulators.

VR Content Management: Companies use this tool to collect, store and analyze VR content based in one location.

VR Game Engine: Developers use this tool to fully experience a video game usable in VR.

Software Development Kit (SDK): SDKs are used to design, build, and test VR experiences.

Social platform software: With the help of this software, users can communicate with each other from far away places.

VR simulators: This software is used for almost all industries that require the training of employees before entering work in certain environments.

Applications of VR technology?

This technology is used to create games, facilitate learning, simulate travel, communicate, and more.

Due to the coronavirus epidemic in recent years, remote work and virtual travel have increased the use of this technology.

Examples of virtual reality applications

VR has influenced various businesses, from medicine to tourism, and is the cornerstone of many companies’ digital transformation strategies. For example, according to Statista’s November 2020 report, business investments in US industrial maintenance and education are projected to reach $4.1 billion in 2024.

Application of VR in education

VR in education

One of the most obvious uses of virtual reality is in the basic training of employees. While this requires the use of a headset today, it can be done on the spot or even at home. As technology advances, VR will become a valuable tool in all areas of corporate training, including situations that require complex decision-making. VR makes more sense in education. For example, assume the experience of being in the past and historical events!

Application of VR in tourism

Hotels can make the experience of entering and using the facilities for you so that you can easily check whether these facilities meet your expectations or not! Instead of using images and videos, you can imagine yourself in those spaces to get a better sense of the decision you’re making.

Application of VR in health

This technology has many applications for researchers, patients, and doctors. Imagine using VR to help patients with disorders like stress or anorexia. In medical schools, it helps students to better learn how to manage the crisis in situations that may cause various issues. For example, teaching empathy to patients in difficult situations! This will be a great event for mankind.

Military application of virtual reality

VR technology is now a valuable tool in simulating combat, confrontation, and the like with a hypothetical opponent. This technology can replace maneuvers and exercises that, in addition to imposing heavy costs on governments, may sometimes destroy the lives of many people in the organization. The ability to change the scenario and quickly implement it to see the results and effects makes its use in the defense and military industries attractive.

Application of VR in entertainment

The ability to deliver immersive experiences is revolutionizing the gaming and entertainment industry. This technology helps Hollywood and movies so that viewers are no longer passive and put themselves in the place of one of the characters in the movie and start playing. Viewers will interact with the stories in a very tasteful way according to their wishes.

But the use cases of the new technology are countless. In architecture to experience basic designs and visualization of space and objects, in the art to remove limitations and be present in different spaces, in aviation to simulate real cabins for students with virtual flight, in aerospace, to inspect airplanes, and in conference rooms to simulate meetings. , colleagues and furniture, in sports, social media, marketing, journalism, fashion, and many similar things. These countless applications show the importance and impact of this technology on our lives.

Challenges of virtual reality

Virtual reality, despite the appeal of engaging multiple senses, has its drawbacks like any other technology. Among them are technical issues, the possibility of user addiction, loss of ability to communicate in real spaces, and costs. Some of these issues may be mitigated, but others will be persistent VR issues.

ِDisadvantages of Virtual Reality


Some people experience VR in games and social media platforms and may become addicted to being in them constantly. People can choose different identities for themselves, which can be addictive and cause psychological, social, and biological problems.

health problems

Extensive use of VR can cause nausea, dizziness, stress, etc., which are also known as simulator sickness.

Loss of human connection

When you rely on virtual communication instead of real social interactions, you may feel depressed and disconnected from society and people. Over-reliance on VR might make you feel that way.


While the price of the required tools is decreasing, VR systems are not affordable for all members of society.

The future of VR in business

Future of VR

Businesses can differentiate their services by combining technologies; Because customers mostly show good interest in innovations. This issue is not more evident in any industry than in shopping and retail.

Virtual reality in retail is still in its infancy. According to a 2018 VR research report, this technology in the retail and marketing sectors will cross the $2 billion mark in 2022. Virtual reality in retail helps sellers and business owners do better planning and research to attract customers. This technology offers companies a strong competitive advantage by keeping up to date with current patterns and trends, such as 3D e-commerce.

Final speech

It has met with moderate popularity so far and it is not possible to give a complete opinion about its future. But when we look at this technology from different angles, it can be said that the scale of success of VR technology in recent years is heavier than the scale of its failure.

The high price of tools, even though in the long run, they save on other things such as transportation costs, has made few people willing to buy its equipment. It seems that companies active in this field will unveil new equipment in the future. This field, despite problems such as alienating people from society, can even bring people closer despite their distance from each other.

All in all, when we consider what good achievements we have achieved in virtual reality in the last few years and the quality of products related to it is getting better day by day and its market is wider, it is better to prepare ourselves for the future and use this technology. Prepare for everyday work.
