VR Box Process

Hello friends! Welcome to the Techmenia Blog post. Today blog post is about what is Virtual Reality and how its work. So, many of you are not know about this technology and its working. Therefore, this is Manish Singh from techmenia will explain every details about this topic. So, stay with us and read whole article for better understanding.

What is Virtual Reality and It’s  Work

Do you know what Virtual Reality is? How is it different from the original reality? What are its different types? If you have to get information about all these things then you will have to read this post virtual reality. Have you ever been to Mars, have ever swim with Dolphins, or have been intercepting any dinosaurs? How will it feel when you say to you that you can still do all these things, even in the same way as if you were dear to that place at that time? Through Virtual Reality, we can revive real reality again. If you want to know more about this then please stays with us.

Virtual Reality is an artificial environment that has been created with the help of software and some special hardware. So that the user gets the artificial environment completely realistic. In a computer we experience this virtual reality; only with its two senses are those sight and sound.

Virtual reality means that the structure of a world that is imaginative on its own but seems completely realistic. For this, high-performance computers and sensory equipment, such as headsets and gloves, are used. This virtual reality is used not only in games and entertainment but also in the training of airline pilots and also in the operation of surgeons, and helps scientists to understand complex problems such as structure of protein molecules. So today I thought why you should give information about what is virtual reality to people in Hindi, which will make it easier for you to understand this technology. So let’s begin without delay.

What is Virtual Reality?

Virtual Reality the two words are ‘virtual’ and ‘reality’. Where ‘virtual’ means near (pass) and reality means such an experience which we feel as human beings (like the truth). Therefore ‘virtual reality’ means the reality of such. This means that it is a particular type of reality emulation.

What is VR Box

Virtual reality (VR) is a kind of experience that is experienced only with the help of computers and hardware. There is such a believable, interactive 3D computer-created world that you can both feel mentally and physically.

So let’s know some essential features of virtual reality:

  1. Believable: As you believe in such a virtual world, you will not know at all whether it is a virtual reality or not.
  2. Interactive: This virtual world will have to move with you so that it appears that it looks much more interactive. If it does not look very interactive then it cannot be called virtual reality.
  3. Computer-generated: This is very important because it is used only in powerful machines, in which the realistic 3D computer graphics is used, so that it becomes so fast that it can be found in the believable, interactive, alternative world Can structure. It can easily turn it into real-time so that it seems to be even more real.
  4. Explorable: A VR world should be large and detailed so that it can be explored in a good way. Whatever the realistic one is painting, but if there is no more details in it, then it will not be more explorable. It is very necessary to be explorable for a better VR.

Immersive: To make VR more believable and interactive, VR must immersive both our body and mind. If something is not attractive enough then it will not be able to attract our mind much, so that we will easily get acquainted with reality. So the more immersive VR, the more real it seems.

So VR is a very different world. This will force you to think that you are living between a completely believable virtual world. It should be two-way interactive, as well as the way you do your movement, your VR also changes according to your reaction.

Types of Virtual Reality

“Virtual reality” is often used in compelling, interactive video games and 3D movies, television programs, at the heart of a marketing buzzword. Therefore many types of VRs are Mehzud according to their different features.virtual reality

So let us know about different virtual realities:

Fully immersive

For a complete VR experience, we need three things. First to find a virtual world, a computer model or simulation. The second is a powerful computer which can be able to detect with ease what it is going to do and adjust it in the same way in real time (as the way things change, the reality also changes, so that real realities Seem like).

The third hardware that has been linked to the computer, so that we immerse it completely into that virtual world. Often we have to wear a head-mounted display (HMD) in which two screens and stereo sound, and one or more sensory gloves. This gives us the experience of a fully immersive VR.


A realistic flight simulator is the best example of a no immersive virtual reality in your home PC, when it uses a wide screen, headphones and surrounds sound, a realistic joystick and other controls. Because not all people need a completely immersed reality. It is a reality in which reality is not completely immersive, but it is close to it to a great extent.


There are many such games like Second Life and Minecraft, which adhere to the first four criteria of VR (believable, interactive, computer-created and explorable), but these are the fifth criteria which do not completely immerse you It does not follow it. But it has a cutting-edge VR that is collaboration: One such idea to share your experience with others in virtual world, which often happens in real time. Collaboration and Sharing is a very important feature in VR’s future.


There was a time when virtual reality was one of the hottest, fastest-growing technologies, in the late 1980s and early 1990s, but becoming more popular with the World Wide Web, people have a little less attention towards it. Computer scientists have learned the method to create virtual worlds in the web even though (virtual reality markup language, VRML) but it could not be more popular. VR’s future web-based and collaborative with Facebook’s growing interest.

Augmented reality

Mobile devices like Smartphone and tablets are just like ours in the supercomputer, because today’s smart devices have supercomputer-like computing power. If we use these smart devices properly then we can use it in many things. We also use Augmented Reality to enhance this virtual reality too. Now the matter arises, what is this augmented reality? In simple words, it is a type of virtual reality, where if we put our smart device in front of a landmark or striking building, then the inanimate object becomes automatic.

This means that Augmented Reality means that it connects our real world with the information of vast virtual world, which we collectively create in the web. These two worlds are not virtual only, but in both of these worlds we explore and navigate, we feel like virtual reality.

What Equipment do we use in Virtual Reality?

If you have ever seen a person using Virtual Reality then you must have seen how they used a lot of equipment. The difference between an simple computer experience and a VR experience is only the nature of its input and output. If you have computer then you know that its works on the equipment like keyboard, mouse, screen, and speech recognizer. This all have to combine together to work. Same this process are VR work, VR sensor can recognized you body movement to provide best reality.

Wherever a PC output is displayed on a screen, VR also uses two screens (for every eye), stereo and surround-sound speakers, along with haptic feedback (for touch and body perception). So let’s know about some input and output devices that are used in VR technology.

Head-Mounted Displays (HMDs)

The difference between VR and an ordinary computer screen is that: In VR, you can see a 3D image smoothly changing, in real-time, as you move your head. This is possible because the user has to wear a head-mounted display here, which looks like a big motorbike helmet. There are two small screens (for each eye), a blackout blindfold which blocks external lights (so that the user does not have any distractions from the real world), and also has stereo headphones.

These two screens display slightly different stereoscopic images, so that a realistic 3D perspective of virtual world is visible. HMDs have made the position sensors and this position sensor are work when you body or head move and fixed image according to this sensors.

Immersive Rooms

Immersive rooms are used according to HMD alternatives. Here the user is placed inside a room where the images on the walls of that room are displayed; they always change from the outside. As you move in the room, the images will also change. Flight simulators primarily use this technique, where images of landscapes, cities, and airport approaches are projected in large screens outside the cockpit. It feels a different reality.


It is true that even if we have any reality, we always have the desire to touch things. In VR technology, we can also feel this thing through Dataglove. These datagloves are equipped with sensors, which have been wired in the outer side of the gloves so that they can easily detect these motions. Here fiber-optic cables are used which are stretched according to the length of the fingers. There are tiny cuts in each cable, just as you do your fingers back and forth, however, more and less light escape from these cuts.

The same happens at the end of a photocell cable, which measures the light of how much light it reaches them. From this the computer knows what the fingers are doing. They use second gloves strain gauges, piezoelectric sensors, or electromechanical devices (such as potentiometers) to measure finger movements.


A wand is even simpler than a dataglove, which is a stick that you can use to interact with touch, point to, or otherwise virtual world. There are position and motion sensors (such as accelerometers) in built in, it also has mouse-like buttons or scroll wheels.
