The most amazing invention of science, the latest technology “Virtual Reality”

 What is this virtual reality?

Well, you dream, don't you? In our daily life, we get many things that we cannot realize the desires of the mind through this dream. In dreams, playing football with Messi-Neymar, making snowmen with Canada's ice from Bangladesh, riding camels in the desert - much more! Sometimes I think it would be fun if they were real! But these are only imaginations, is it real again?

Hmmm, turning these fantasies into reality is "virtual reality". The science-based imagination that is not real in the real sense but that initiates the consciousness of reality is called virtual reality or the reality of feeling or fantasy reality. Virtual reality is a computer-controlled system that allows humans to interact with or perceive an artificial three-dimensional sensory environment through the application of modeling and simulation. In virtual reality the simulated environment can be exactly like the real world. In this case, real experience is often obtained from virtual reality. Sometimes the simulated environment may differ from the real one. Eg: Virtual reality games. It makes it possible to do impossible tasks by creating three-dimensional (3D) images.

In virtual reality the user is completely immersed in a computer controlled environment. Reality is perceived in virtual reality by wearing head-mounted displays, data gloves, full body suits, etc., containing various devices that exchange information. By this, it is possible to decorate with desired objects, fight with friends, dance and express emotions graphically.

Let's look back a little.

About the middle of the last century. A cinematographer named Morton Hillig envisioned a kind of cinematic technology for his audience that would enhance the feeling of watching a movie, taking them deeper into the story. From this dream, around 1957, he invented a device called 'Sensorama'.

Hillig's machine could be used by up to four people at the same time. Here he juxtaposes scents, stereo sound, seat movement and hair blowing in the wind with 3D motion pictures. And this is how Hillig used to introduce his audience to another world which is real but unreal! He is called the 'father of virtual reality' for this extraordinary invention of Hillig. Since then, due to the tireless efforts of various scientists, virtual reality has reached its enviable position today.

I babbled for a long time! But if there is no practical application, what to do after listening to the "story"? 😕

So! What is the application of this in practice?

Let's see where this artificial world is playing a role in our current world.

The effect of this "unreal" thing in our real life

First let's talk about education. Many times it is seen that we are reading about something and how that thing behaves in different situations, we either read the book in our mind or watch its video from the internet. But virtual reality makes this task easier for us. He takes us into a world where we have the feeling of seeing the same thing face to face, thus deepening our understanding of the thing.

Virtual reality plays an important role in the construction of various buildings. Nowadays many architects create virtual models of their building plans. Clients can then easily tour the inside and outside of these buildings and suggest any changes if needed. And these are done before the building!

Virtual reality has a strong foothold in the world of sports. It is widely used for training in various sports like golf, athletics, cycling etc. In addition, virtual reality has also been successfully applied to design various materials used in sports; For example, Running Sue.

This important discovery of modern science is being used very well in the military field these days. It is used to create artificial environments for combat simulations and treatment of wounded soldiers for the military. They even used this technology to recruit soldiers in the British army. The Navy has utilized virtual reality by developing submarine simulators. And this technology is also used in the air force. Flight simulators are used to improve various flying skills, deal with emergency situations, etc. In addition, virtual reality has also contributed to the creation of various virtual friends, armed warships, submarines equipped with virtual torpedoes.

Virtual reality is now so widely used in the medical field in the modern world that it goes without saying. Let's talk about the doctors first. Surgery simulation is now used to make a doctor more proficient in various subjects. As a result, a doctor can learn many new things without any accidents! A similar system is in place for the training of nurses. This technology also has gifts for people who have been crippled by various accidents. Let's say a person is now using a wheelchair due to an accident a few days ago. It is normal for him to have trouble using it at first. And this is where virtual reality comes in. He is creating an artificial environment of a busy street or a market for this man so that he can at least practice here before applying it in real life. Different types of phobias make our normal life quite miserable. Virtual reality is helping people with phobia to get out of their phobia by creating various artificial environments. There are many other areas in the medical field where this technology continues to make its amazing contribution.

Apart from these, virtual reality has an important role in entertainment, business, media, cinema, telecommunication, scientific research, fashion designing etc.

Devices.

So far we have known about the various contributions of virtual reality in our life. But how do we enter this artificial world? In fact, there are many types of devices for moving around in the virtual world. Various types of virtual reality products include HMD (Head Mounted Display) devices, motion trackers, head trackers, VR Domes, VR software/kits, VR simulators, etc.

Future challenges

One of the most challenging aspects of virtual reality is developing advanced tracking systems, making real interactions with artificial environments more realistic. Although there are a few companies from its inception for research on this subject, they face many limitations. Sometimes even a virtual reality developer has to rely on a technology that was originally intended for a different purpose. And creating an artificial world is really a laborious and time-consuming task. The more realistic the world, the more time and effort it will take. So the more diligent and patient you are, the more likely you are to succeed in this artificial world.

Some negative effects

Most things in our real life have more or less pros and cons. The education acquired from childhood will tell us which path we will take. Virtual reality also has its pros and cons.

People who spend time in these virtual worlds in a very violent environment have adverse effects in their real life as well. Many people are also affected by cyber addiction as a result.

Another thing to think about is that things like murder and sex are covered by laws in our real world, but in the artificial world? Various studies have shown that in these situations in the artificial world, a person experiences mental and physical feelings just like in real life. As a result, it is also a matter of thinking whether virtual reality will actually damage our sense of humanity. And so anyone who wants to proceed with this issue should proceed with these limitations and cautions in mind.
