What is Virtual Reality

What is Real and Virtual

Friends, today I am going to tell you about real and virtual (VR) technology, which will have an impact on our future in the coming time, how will it be good or bad, how will we benefit and how will we be harmed, and It will also make our work easier in many ways and you know that if there is any advantage of anything, then it also has some disadvantages, then I will tell you everything about them, I will try my best to give you a lot of information. Give more accurate information so that you can know what are its advantages and what are the disadvantages, but in this blog I will tell you completely what is V-R technology, so read it and enjoy if you face any kind of problem. If you see it, you can tell me by commenting.

In simple words, Virtual Reality is a way of creating a computer-generated environment that takes the user into a virtual world, i.e. immersing in a way. When we use VR headset or put it in front of our eyes, it takes us into a fake set-up or virtual world, which means that our brain starts feeling like real and thinks that We are doing this work in real, so that we are completely isolated from the real environment (real world), we feel like we are doing all this in real. If you have ever used or used it, then you will understand what I am trying to tell through this post.

How Virtual Reality Works |

To understand how real and virtual gadgets work, you have to take care of some technical things. Come and in the future, if you have to use gadgets like this, then you can also use them well, the primary subject of virtual reality is the simulation of vision. Every headset aims to perfect its vision to create an immersive 3D environment. Each VR headset puts a screen (or two - one for each) in front of the eyes, thus, eliminating any interaction with the real world. Two autofocus lenses are usually placed between the screen and the eye, which adjust based on the movement and position of the individual eye. Views on the screen are provided using an HDMI cable connected to either a mobile phone or a PC.

There are a few prerequisites for creating truly immersive virtual reality — a frame rate of minimum 60fps, an equally capable refresh rate, and a minimum 100-degree field of view (FOV) (though 180 degrees is ideal). Frame rate is the rate at which the GPU can process images per second, screen refresh rate is the speed of the display to render the images, and FOV is the range in which the display can support eye and head movement. But nowadays it is given in these advanced technology, you just have to keep your mobile in the wire box and then after that you can do this technology but in this post I am just trying to tell you how it works. And it contains different types of material, you can use it according to your need!

If you can't connect any of the parallels properly then your veer box may not work properly and even if none of these devices work properly, the user may experience latency. i.e. too much time difference between your actions and the response from the screen. We need a response of less than 20 milliseconds to trick the brain which is achieved by mixing all the above factors in the right proportion. Another issue that should apply here is preventing bursting (cyberspace), which results in inconsistency between frame rate and refresh rate. If the GPU's FPS exceeds the screen refresh rate, the image may be distorted. To combat this problem, we limit the refresh rate of the monitor using a sync, called vertical sync (vSync).

Among the major headsets available today, the Vive and Rift both have 110-degree FOVs, the Google Cardboard features 90, the GearVR 96, and the new Google Daydream up to 120 degrees. As for frame rates, both the HTC Vive and Oculus Rift come with 90hz displays, while the PlayStation VR offers a 60hz display.

If you face any kind of problem like I have also used some technical words then don't worry I have told this virtual reality journal and it provides all kinds of facilities at its own level and if you have any problem Still, if you face any kind of problem, then you can comment if you want, I will definitely reply!
