Introduction

Playing games is the most trending thing that half of the population in the world does in their lives. The days are gone when we play games on mobiles, now the 3D animation games and videos are emerging from a few years ago and people adopt this technology rapidly. This is the kind of thing that is difficult to differentiate between the real world and the animated one.

Not only video games but there are lots of other inventions are included in this technology, like watching 3D movies etc. This new emerging technology is known as Virtual Technology. It creates the world of illusion, we can experience this like it is happening in reality, our eyes and mind react as they take action in the real world when something has happened.

Well, it seems like an effective full technology. But how does it work? Can “Virtual Reality” change our mind? If not then why do this technology have attracted our attention.

What is Virtual Reality Technology?

The basic definition of “Virtual Reality Technology” is an “Artificial Computer-Generatedworld that can be experienced and interacted as, a video game or movie which seems real by the creation of illusions. This term has come to refer to experiences when the user or player uses special equipment to involve themselves and completely block out the real world.

Virtual Reality is a built with the help of HMD called Head Mounted Display the equipment that looks like sunglasses put on our eyes. It helps us to see images, the motion pictures that come in front of us when we put them. So what is going on inside is a little bit of a different story from outside that world? Seems like fun? But why does technology need this system and what is the purpose of inventing such a wonderful technological world for humans? To answer these questions it is important to know where this idea came from? Here is a small amount of history that can help us to understand more about this technology.

History of Virtual Reality Technology

“Panoramic Paintings” is an artwork done in the nineteenth century intended to fill the viewer’s entire field of vision and making them feel present at some historical event or scene. This was something like the first attempt towards Virtual Reality.

“1838_Stereoscope Photo and Viewers” by Charles Wheatstone’s research brings the idea of two-dimensional images that the brain is able to process them like real-world images from each eye into a single image. The later development of the popular “View-Master Stereoscope” which was used for virtual tourism, this design of stereoscope is now used in low budget VR head-mounted displays.  While in 1930 the era of “Science Fiction Predicting VR” by “Stanley G. Weinbaum” started.

He introduced the idea of a pair of goggles that let the wearer experience a fictional world through “Holographic”, smell, touch, and taste. Somehow it's like a now a day Virtual Reality which shows the fiction world like reality. Many discoveries in this technology were made in the next years.

  • In 1950s Morton Heilig’s Sensorama, a theater with the feature of 3D display in it.
  • In the year 1960 Morton Heilig invented “Head Mounted Display” the glasses which show us the illusion world.
  • In 1961 first motion tracking HMD has come in front of the human eye developed by “Comeau & Bryan”.
  • Year 1965 ultimate display by Ivan Sutherland, the 3D world becomes realistic by sounds, and a person is able to interact with objects in the virtual world in a realistic way.
  • In 1969 artificial reality by “Myron Krueger” in which he created an environment that responds to the people in it. From all the above inventions, 2019 was the year when this technology changed into another stage as we see now the bitterness of visuals, the changing in virtual reality it seems more and more real.

Virtual Reality is not an individual technology, different types of this technology create a system which is collectively called VR technology, the following are types of VR.

Types of Virtual Reality Technology

Among the tons of VR formats, these are the most inflectional ones. Let’s learn more about each of these formats.

1. Non-Immersive Virtual Reality, the type of VR in which a user is experiencing the virtual through a computer and can control some characters or activities within the software, but the environment does not directly interact with that user.

For more clarity let's take an example of video games, the car race, or some fighting games, you can control the characters right within the game, these games have their own animations and attributes.

Technically you are dealing with a virtual world but, you are not the center of attention in that game. Basically, all forms of gaming devices such as computers, PlayStation, are providing you a non-immersive virtual reality.

2. Fully-Immersive Virtual Reality, well it is something like you face in real life, emotions, actions, and the environment of fully-immersive virtual reality provide you a world which is full of illusions, and once you in it seems difficult to leave that world. It is the physical world that looks like everything is happening to you in real life.

This is an expensive form of virtual reality that involves helmets, gloves, and body connectors with sensor detectors. These are connected to a powerful computer. Your movements, reactions, and even a blink of an eye are detected and project within the virtual world.

Therefore you feel like within that virtual physical world. One of the best examples is the virtual shooter gaming zone where you are fully equipped and you can move your arms, legs, body, you can also jump, run, and do many other things. Well, this type of virtual reality is also helpful in operating the serious operations of the brain as medical training looking for some fruitful advantages from this virtual reality.

3. Semi-Immersive Virtual Reality, it is something like a mixture of both non-immersive and fully immersive reality. This can be a form of 3D space or virtual environment where you can move about your own either through a computer screen or a VR box. All the activities in the virtual world are concentrated on you.

Most semi-immersive virtual environments support Gyroscope, which means the virtual space will be fixed on your phone based on the virtual axis, and you have to move your phone in different directions to view the virtual environment in those directions. The ones that are connected to a VR box become more interactive and you are only able to see the virtual environment and not the real world even with the corner of your eye, due to this creating a realistic experience.‌‌

4. Augmented-Reality, the type of VR in which a certain entity or device seems to be present in reality but is actually not. Rather than put you into a virtual world, a virtual entity is placed in the real world through any device.

For more clarity take an example of a mobile screen, you view your room, and probably place a cartoon character at the corner of your room. You can see cartoon characters through a mobile screen but not in reality.

Well in Snap-chat filters sometimes these characters are included. We can see a dancing girl or a cat in the room through the mobile screen, and when we change the filter the character is gone.

5. Collaborative VR, this is something like PUBG game which also gained popularity in recent years. PUBG is the most adopting game at a global level especially young generations are more attracted towards this game. Well, it is a type of collaborative virtual reality, in which different people from different countries or areas take place within one game.

They can play together although they are far away from each other. You can talk to each other. This sounds of running, fighting, and the whole animated environment is part of this virtual reality where a person can interact with the real-world and animated world at both times.

From all above, recently people are not only using these types of virtual in games but also to join online meetings, for online debates and many businesses are taking advantage of this face to face new animated technology.

By adding up the applications of Virtual Reality we can see the use of this technology in different fields.

Top 7 Applications of Virtual Reality Technology

This year, Virtual Reality finally gets real in terms of applications and usage. This technology has revolutionized many different industries specially the video games. In 2020 and upcoming years there are unlimited applications of VR in other industries.

1- Films / Movies

We already have 3D theaters through which people can enjoy more than only watching the movie. Virtual reality can make the audience feel more involved in whatever they are watching as they are a part of the narrative itself. Some movies and films who adopt this technology are the followings,

  • Notes on Blindness, an Australian author John Hull, when he lost sight in the 1980s, was learning to cope up with, while taking down notes of his experiences. Note on Blindness movie uses virtual reality and allows the audience to immerse themselves in the life of blind people, understanding how it is like to live every day without their sense of sight.
  • Bashir’s Dream, one of the greatest films by using virtual reality in which a Syrian girl refugee named Quasi Bashir Masaama, was shot in the back by a sniper. The film transitions wonderfully from past experiences to present living conditions to future dreams of Bashir’s.

2- Sports

Sports is the important part of our lives. People want to enjoy their favorite game while without leaving their homes. VR takes responsibility to entertain people through sports. “LiveLike VR”  has created a virtual stadium for them where they can watch the game in a way they are living inside the stadium. The platform can make them experience the thrill and excitement of sports games, alone or with their friends at home.

Not only fans, but athletes themselves benefit from VR technology as well. The American football team practice their game through a simulation, improving their work, and individual skills without stepping on an actual field.

3- Communication and Collaboration

Remote jobs are increasing day by day which is beneficial as they save time and effort. The productivity is increased but the main obstacle for remote employees is that they need effective methods for communication and collaboration better than regular voice or video communication methods available.

Well, with the help of VR, teams can attend meetings to communicate and collaborate efficiently in a virtual environment without the need for the physical effort and away from any kind of distractions.

The isolated virtual work environment will improve productivity for meetings and training sessions while reducing the cost of the physical workplace for employees and conferences. ‌‌

4- Medical and Health Care

Healthcare is another field that has benefitted from VR applications as medical staff for doctors, surgeons, and nurses. By the use of VR they will be trained for daily life-threatening tasks and situations in a virtual customize world to improve their required skills and handle an emergency situation with a higher number of human injuries or surgeries accidents or natural hazards.

Just Imagine how many lives will be affected by skilled medical staff trained for different kinds of situations. Treating psychological disorders like “Post-Traumatic Stress Disorder(PTSD)” and “Phobia” is also possible with virtual reality, by training a patient how to face these situations step by step gradually until overcoming their fear and experiencing more confidence. Well, this is possible all thanks to VR. ‌‌

5- Marketing and Advertisements

Traditional marketing and advertisements channels methods are less convincing nowadays as they field to upgrade to target customer’s mental development levels that require more interactive belief techniques. VR promotional videos are an interactive technique to encourage customers for the investment of your business products and services by providing virtual experiences about how these products can add value to their lives and satisfy current and future personal and business needs.

Content marketing performance is also enhanced with customized VR solutions as many content creation organizations adopted VR to increase engagement with their content.‌‌

6- Education

If students are studying history, physics, and any subject they can experience studies through VR by creating a world in which they can see things in detail very clearly in front of their eyes, which also seems real. This is so beneficial for students, as they can understand better when they experience clearly.

Organizations are now going towards productive learning to create a well informative world in educational fields. Not only this but those students who are unable to attain schools can also take advantage of this technology by sitting in their homes and through virtual reality study themselves.‌‌

7- Space Exploration

With the help of VR technology, NASA gives us another vision to explore the universe. Due to natural conditions, NASA at some point failed to explore more about the universe, but now they are able to see more things in space without any risks. They are trying to control a robotic arm using the combined technologies of the “Oculus Rift Head,  “Kinetic 2 Sensor”, and “Xbox One” game console. According to NASA researchers, this setup might be controlled space robots and other instruments that are far, far away from us someday.

On another hand, the researchers are conducting a walk on other planets by taking help from VR technology in the future. This shows us that VR technology is more than what we only know about it. ‌

Conclusion

A new world of illusion is coming towards us, by creating a space in which we can able see what we want to see and create. It is surely a great way to communicate, to convey our ideas easily. It will help us to explore more about our nature and outside the space.
