The rapid development of virtual reality (VR) technologies is rightfully considered one of the brightest IT trends. Having originated as a kind of computer games, it quickly outgrew this stage. Modern VR devices and software platforms provide it with a truly transcendent level of realism and user engagement. Thanks to this, for many people, virtual reality has become a full-fledged alternative to real life.

Given the high relevance of this topic, we decided to devote our next article to it. From it, you will learn about what virtual reality is and how VR technologies work. We will also talk about how can virtual reality help us, can it change our world, and when will VR be real? At the end of the article, we will introduce you to a small comparative analysis of two realities: Virtual World vs Real World.

What is VR?

Virtual reality is a three-dimensional world created using computers and other technical means that can completely replace the real world through human sensations (vision, hearing, touch, smell). Thanks to this, users can perform the same actions in it as in real life, having contacted the virtual world and objects in it in various ways.

Participants have the opportunity to immerse themselves in virtual reality through a set of VR devices designed for it: such as glasses, helmets, headphones, gloves, etc. Another important component of VR is special programs that create the necessary graphic, sound, tactile or other types of interfaces.

In addition to facts about virtual reality, it is worth highlighting several key characteristics of this technology:

  • Simulation in real time. VR technology should instantly create a complex of effects for participants: image, sound, tactile or other sensations. To do this, it needs to be able to simulate these effects in real time without noticeable delay – in the form of an instant reaction to certain user actions.
  • Realistic imitation. A high degree of realism is another important feature of virtual reality. It should provide users with complete immersion in an alternative world, and for this, the surrounding space and all objects in it should look and feel as realistic as possible. So far, technology cannot provide it with 100% resemblance to reality, but progress does not stand still and, perhaps, soon the question “Do we live in virtual reality?” will become really relevant.
  • Single-user and/or multi-user mode. VR-systems are individual and collective. The latter support the simultaneous participation of a limited or unlimited number of users. At the same time, their participants can flexibly interact both with the virtual space and with each other. Multiplayer systems include the currently popular VR platforms Second Life, Meta Horizon Worlds, Sandbox, Decentraland and others.
  • Interactivity. Users of VR systems have the opportunity not only to observe the virtual space and objects, but also interact interactively with them. The scripts and scenarios programmed in the interface are executed in accordance with the actions of users: walking, movements of hands/fingers/eyes/lips/other parts of the body, facial expressions, voices, etc.
  • Stereoscopic image. Virtual reality should have a stereoscopic image, which makes the picture three-dimensional and creates a sense of depth of space.

How Can Virtual Reality Change Us?

Given the relevance and great prospects of this phenomenon, many community members are wondering – How will virtual reality change the world? And some of them go even further, asking – When will virtual reality be real? And if the second question still remains rhetorical, then the answer to the first one is gradually becoming clearer. VR technologies really have the power to change the world, and they are already changing it right now. Next, we will consider some areas where virtual reality effectively helps a person in his activities.

Medicine

VR has a particularly wide range of applications in the field of medicine, and here it can provide support in several directions at the same time. One of them is diagnosis – using virtual reality, doctors can quickly and accurately determine the diagnosis and clinical picture remotely without direct contact with the patient. In addition, VR technologies can also work in the opposite direction, allowing doctors to clearly transmit information about diseases and the characteristics of treatment with visual interactive methods.

Virtual reality can also become an effective tool for training medical personnel. Its interactivity makes it the perfect sandbox for practicing surgeries and other procedures. And thanks to its virtuality, it is absolutely safe, since possible mistakes by doctors will not have any consequences for real patients.

An equally important area of virtual reality is the diagnosis and treatment of mental disorders. For example, these technologies have demonstrated their effectiveness as a way to cope with various phobias, as well as anxiety or depression. The use of virtual reality in real life can create a controlled and safe environment in which patients may encounter their fears and injuries to overcome them. There are already successful cases of treatment of fear of heights with the help of virtual simulators, and a suitable method for treating psychosis is currently being developed.

Education

Will virtual reality replace reality? The possibilities of VR in the field of education are a very clear answer to this question. Indeed, the prospects of these technologies in the field of training and professional development are truly limitless. Virtual reality makes quality education more accessible to everyone. Moreover, this applies to literally all its levels and directions – from general to highly specialized or professional areas.

VR allows students not only to study individually, but also to flexibly interact with teachers and among themselves. The technology makes it possible to virtually attend lectures and seminars at different universities, as well as tours of the best museums in the world or even different historical eras, planets, etc. Virtual reality has been shown to be highly effective in teaching children with certain disabilities, such as autism.

High-risk areas of activity

Another popular scope of VR technology is a number of specialties associated with high risk to human life and health. These include military, police, firefighters, etc. Such experts regularly face many dangerous situations that are difficult or impossible to simulate in reality. Nevertheless, virtual reality copes with this task, allowing you to reproduce various scenarios of the development of events with complete immersion and participation, but without real threats.

VR provides huge potential for the development of realistic interactive simulators. With their help, you can effectively practice acquired knowledge and skills in conditions that are as close to reality as possible. At the same time, virtual reality training is absolutely safe for all participants in the process, and also does not require the cost of equipping training centers, equipment, weapons/ammunition, etc. VR technologies are universal and can reliably simulate any area and type of training.

Entertainment industry

Virtual reality has been able to radically change the modern entertainment industry, making it much more interesting, exciting and dynamic. According to statistics, more than 66% of users would like to use VR to watch movies, TV and online videos. They find that this technology makes their browsing experience richer and more engaged.

Separately, it is worth noting the video game industry, where the technology of virtual reality was born and developed. To this day, it is one of the most popular and sought-after areas of its application. VR technologies are used in many popular games, providing players with a completely immersive gameplay experience. In addition, multiplayer simulation games (Second Life, Meta Horizon Worlds, etc.) are widespread. They allow players to create virtual personalities-avatars with ample opportunities to interact with the outside world and other participants.

Sport

Sport is an equally promising area for the use of VR technologies. Virtual reality simulators provide an opportunity to hone skills in various sports conveniently, affordably and effectively: cycling, skiing, golf, athletics, etc. Interactive 3D platforms help train technique and movement mechanics, as well as measure and analyze results. VR is also well established as a tool used in the design of sportswear, shoes and equipment.

Virtual Reality – Advantages and Disadvantages

At the end of the article, we would like to describe the main pros and cons of virtual reality, compared to the real world. Its advantages include the following:

  • Versatility. VR technologies are already used in various fields, and in the future their volume can become unlimited. Entertainment, rest, training in professional skills, social interaction and much more – virtual reality can radically change all the main actions and areas of human activity.
  • Development of thinking and other personal qualities. Virtual reality allows you to create absolutely any scenarios and forms of activity. Participation in them gives players the opportunity to develop non-standard thinking, train reaction speed and other useful qualities. In the future, this may be useful to them in real life.
  • Socialization. VR is an effective tool for communication and interaction with many people from different countries of the world. It provides broad prospects for socialization, especially for people with disabilities.
  • Business. Modern virtual reality platforms are a promising space not only for personal development, but also for business development. Their participants can conduct virtual business (buy/sell virtual objects, etc.) and earn NFT tokens that can be exchanged for cryptocurrency and real money.

However, when comparing virtual reality vs reality, it is worth noting some VR deficiencies:

  • Complexity and cost. The development and implementation of virtual reality technologies in many areas (for example, for vocational training) today remains a rather complicated and expensive procedure.
  • Addiction. Psychological dependence on VR platforms is considered an important problem, especially for multiplayer games. And the anonymity and the illusion of permissiveness makes them potentially attractive to intruders.
  • Harm to health. Prolonged immersion in virtual reality can lead to a number of negative consequences for the human body. In particular, cause dizziness, weakness, nausea and disorientation.

Bottom Line

Now it is clear that virtual reality is not a fleeting trend, but a very useful and promising IT technology. Of course, in the near future this is unlikely to replace a real life, but in the future it is quite possible. Today, VR is closely connected with many aspects and areas of human activity: from films and computer games to medicine, sports and special services. Modern virtual reality platforms provide people with literal alternative life thanks to the virtual characters with wide freedom of action. Nevertheless, you can see certain disadvantages of VR technologies, which can become even more relevant in the future.
