So without further discussion, let’s get right into it.

How Does VR Work?

The main thing needed for a VR experience is a virtual reality headset. This includes the VR software that makes a virtual world appear around you. The main components of a headset are sensors, lenses, and a strap to keep the headset in place.

Firstly, two lenses are present in most headsets, which can often be adjusted to the right focal length. The incoming images are split into two, one for each stereoscopic lens. The images can move left to right giving you the 3-dimensional effect.

Secondly, immersive audio also plays an important role in mimicking the real world in the virtual version. The VR content adds depth to the sound you hear, improving the experience.

Lastly, controllers can often be used when playing VR games. These enable you to pick up, move and drop objects in the virtual world. They also come in handy in action games.

There is a set field of view, specific to each headset that lets you roam around in VR. This is possible due to several sensors present in the headset. These track your movement and the software feeds 3D images into the screen to let you explore.

How To Experience VR?

 How does VR work?


The first thing you need to experience virtual reality is a virtual reality headset. There are 3 types of headsets available:

  1. Standalone VR
  2. PC tethered VR
  3. Mobile VR

We suggest purchasing a mobile VR first to get an idea of the virtual world. Once experienced, you can move to Standalone and PC tethered VR. After you have a headset, you can connect it to a PC or insert your mobile device to get started.

A few of the headsets you can check out are the Oculus Quest 2, Valve Index, and the Samsung Gear VR.

Play Space

It is important to have an empty place while you are wearing a headset. With your eyes covered by the headset, you might bump into nearby furniture and hurt yourself if the space is not cleared. 

For a safer experience, using your virtual reality headset in an empty room is a good idea. However, be sure to not run into the empty walls!

VR content

There is a lot of free and paid VR content available out there you can enjoy. Depending on the headset you own, you can explore movies, games, and virtual tours on YouTube, SteamVR, and the Oculus Store. 

You just need to select the content you want to watch and strap on your headset for an immersive virtual experience. You can start by checking out free content and then purchasing different games and videos.


This is not a necessity for all VR experiences but can be a good purchase. You can use controllers in multiple VR games to navigate and move around the virtual world. You will be able to use them as guns in action games or pick and drop objects from one place to another.


Firstly you should make sure to have a clear play space. This avoids any stubbed toes and crashing into furniture. Be sure to take breaks between sessions as well. We suggest taking a break of 10 to 15 minutes after every 30 minutes of watching.

If you watch at long intervals, you may suffer from eye strain and headaches. Along with that, if your headset is heavy, it may cause neck strains.
