virtual reality An artificial environment that is created with the help of software. In addition, it is presented to the user in a way that prompts the user to be real. That is, it is very easy for the user to believe that what he is seeing, hearing and feeling is really present.

He accepts it as the real environment. With the help of computer hardware and software, a completely realistic environment is created. But in reality it is just an imaginary environment.

So today I thought why don’t you guys what is virtual reality Let me provide information about in Hindi, which will make it easier for you to understand this technology. So without delay let’s start.

What is Virtual Reality

Virtual Reality Combination of two words’virtual‘ And ‘reality‘. Where ‘virtual’ means near (near) and reality means the experience that we human beings feel (like the truth). Therefore ‘virtual reality’ means like reality. This means that it is a specific type of reality emulation.

What is Virtual Reality in Hindi

Virtual reality (VR) is a type of experience that can only be achieved by computers and Experience is done only with the help of hardware. A believable, interactive 3D There is a computer-created world that you can feel both mentally and physically.

Features of Virtual Reality in hindi

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

1. Believable:

As you keep on believing 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 be moved with you so that it appears that it looks more interactive. If it does not look much interactive then it cannot be called virtual reality.

3. Computer-generated:

This is very important because only powerful machines, in which realistic 3D computer graphics are used, are used so that it is so fast that it can create a believable, interactive, alternative world. With this, it can easily be changed in real-time, which makes it appear more real.

4. Explorable:

A VR world should be big and detailed so that it can be explored in a good way. As realistic as it is a painting, but if it does not have much details then it will not be much explorable. It is very important for a better VR to be explorable.

5. Immersive:

To make VR more believable and interactive, VR has to make both our body and mind immersive. If something will not be more attractive then it will not be able to attract our mind much so that we will easily come to know about the reality. So the more immersive VR is, the more real it will seem.

So VR is a very different world. This will make you think that you are living in the midst of a completely believable virtual world. It should be two-way interactive, so that the way you do your movements, your VR also changes according to your reaction.

Which equipment do we use in virtual reality?

If you have ever seen a person using Virtual Reality, then you must have seen how they use a lot of equipment. The difference between an ordinary computer experience and a VR experience lies in the nature of its input and output.

where an ordinary computer Uses equipment like keyboard, mouse, speech recognition for input, while VR uses sensors to detect how the body is moving.

Where a PC displays the output on a single screen, VR uses two screens (one for each eye), stereo and surround-sound speakers, as well as haptic (for touch and body perception) feedback.

So let’s know about some input and output devices which 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 changing smoothly, in real-time, as you move your head.

This is possible because here the user has to wear a head-mounted display, which looks like a big motorbike helmet. It consists of two small screens (one for each eye), a blackout blindfold that blocks external lights (so the user has no distractions from the real world), and stereo headphones.

These two screens display slightly different stereoscopic images, so that a realistic 3D perspective of the virtual world is visible. HMDs usually have built-in accelerometers or position sensors that detect how your head and body are moving and adjust the picture accordingly.

Immersive Rooms

Immersive rooms are used as an alternative to HMD. Here the user is kept inside a room where the images displayed on the walls of that room are always changing from 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 into large screens outside the cockpit. This gives a feel of a different reality.

Datagloves

It is true that no matter what the reality is, we always have a desire to touch things. Even in VR technology, we can feel this thing through Datagloves. These datagloves are fitted with sensors which are wired to the outer side of the gloves so that it can detect motions easily.

Here fiber-optic cables are used which are stretched according to the length of the fingers. Each cable has tiny cuts, as you move your fingers back and forth, more and less light escapes from these cuts.

There is a photocell at the end of the cable which measures the light how much light reached them. This allows the computer to know what the fingers are doing. Whereas other gloves use strain gauges, piezoelectric sensors, or electromechanical devices (such as potentiometers) to measure finger movements.

Wands

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