Reality is generally what we sense our experience. Virtual reality, VR in general words we say, the experience we get in fake world.

We know the world through our senses and perception systems. In school, we all learned that we have five senses: taste, touch, smell, sight and hearing. These are however only our most obvious sense organs. The truth is that humans have many more senses than this, such as a sense of balance for example.

Technically, Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions.

Presently, VR is being used in many fields.

VR in games:

Imagine your given a chance to take a gun and run in the in the war zone to kill the opponents. Practically, it’s a criminal activity if you have no qualification to do it. But with VR, you can. VR stimulates graphically designed 3D environment where you get original experience of killing someone(self satisfaction if it’s your real life enemy). Yes, we are talking about games. Games are the biggest booming business, right now, in the world.

Imagine you’re in space, left alone in warship, full of weapons, surrounded by enemies, ready to blow you to the hell and you have to destroy everyone to survive. Now just stop imagining, it’s now practically possible with VR. EVE: Valkyrie – Warzone is a VR game from CCP games and KEA games which actually allows you to experience it in VR. Below link shows you a glimpse of gameplay.

Likewise there are many other games, where the things you can’t experience in real life can be done in Virtual Life.

VR in Military & Air Force:

Have you ever wondered how the military troops aims and fires exactly at the opponent. Well, the answer is they get trained. But we don’t get opponents all the time to practice and train, right?

Well, here also, VR plays a major role in training the soldiers. Developers, using Unity(software to create 3D environment), created a artificially intelligent environment(not game), where the guns and other weapons are virtualized, which recognises the external environment movements and produces it in virtual environment.

In the same way, Air Force also trains it’s soldiers on how to fly a plane and what to do if an unexpected event, like engine failure, occurs all of a sudden. This shows the spontaneity of the pilot and whether he will be suitable to Air Force or not.

Even the training for bomb diffusion also given in VR. Have a look in the below video

VR in Driving:

No, don’t get confused with self driving cars and VR driving cars. It’s actually, learning to drive a car. Yes, years backs, there we game studios where a handle is given to us and road will be shown on the monitor. We have to move the handle(or call it steering) to drive in the game.

The same concept is used here. But again, using VR games. A 3D environment is created in Unity with AI and Machine Learning concepts where real world traffic is analysed and the those scenarios will be generated. Frontier Driving Academy has introduced it and also made an video of how it would look.

VR in Construction:

Have you ever felt to see your dream house how it would look before you actually built it. Well, VR again. This is also made possible with it. Civil Engineers in construction field design your dream house plan and software/VR engineers in the company generate it virtually to create pre-experience on your house.

Even it is also being used to educate the employees in construction field about the safety measures they have to take while they are on the field. Take a look on it in the below video.

VR in Automobiles:

This is the one I have been waiting to tell about. Have you ever think of how would it be to dismantle a car and see each and every part in it. Or to change the colour of car immediately to see how it looks, or the engine to check it works with different engines. Exactly, more than this is being done in the field of Automobiles using VR.

When it comes to this part, Tesla and Ford occupies a special place in my heart. These two companies majorly started to analyse the working of car in VR mode. That is why, they have best performances on the road. They give customer satisfaction before purchasing the car. User can actually experience it by getting into VR mode for different cars. Take a look on below videos.

VR in education:

In 2015, the Western University of Health Sciences in California became the first American medical school to offer VR-assisted training to its students. University used headsets like the Oculus Rift to give medical students VR tours through the human body.

It’s similar to how both elementary and high school students have begun using VR to visit places that are otherwise inaccessible via conventional means, such as the inside of a live volcano and the surface of Mars.

Even in the field of engineering also, students use VR to analyse the parts of high costly equipment without any cost. The only one time investment was to buy the compatible VR headsets and the required software. Many parts of India also started to use these resources to train their students and to provide hands-on experience virtually.

VR for Physically disabled:

Have you ever seen a physically disabled person getting mentally disturbed by knowing that people at his age are doing lot of things but I am here, not even able to move.

Have you ever listened from your grandparents saying that “I was a traveller once but now due to my age and body condition, I am not able to go anywhere”. (I don’t know about the people reading this, but I have experienced this. I wish we had this technology at that time.)

See the video below. It shows a physically disabled person playing piano with an eye tracking VR head mount.

In the same way, people can visit the places they want just by sitting in a wheelchair even by not moving a inch. That’s how the technology is bringing the changes life of people.
