What is Virtual Reality?

October 21, 2018

Have you seen those big size headsets that people wear and go absolutely crazy? Yes, stop right there as that’s what we call a Virtual Reality experience.

For Dummies, a Virtual Reality space immerses the user into a computer-generated digital environment. A person with the headset on can explore and interact with the three-dimensional surrounding leaving the real-world behind. Today, the virtual reality is merged with physical environments and various props to generate a realistic sensation and feel.

How it works!

So you have purchased the whole equipment to dive into the world of virtual reality but what about the backpropagation behind it? Today, we’ll explore on what basis does the VR technology works to give you a supreme real-life essence.

  • The Elementary Knowledge

VR technology aims to create a real-life environment to stimulate the user’s vision from the surrounding. No matter which headset you choose, Oculus Rift or Google DayDream every single one’s primary goal is to create an astonishing 3D domain for you.

Inside the VR headset, there is one screen with an auto-focus lens for each eye to disconnect the user from the real world. Furthermore, the lens is placed in between the screen and eye to adjust the eye movement and positioning for a proper experience.

The headset is attached to the phone or connected to the PC through an HDMI cable for displaying the visuals on screen.

  • Depths

Suppose you are surrounded by hundreds of 4k display but do you actually feel a digital environment? Here is where VR excels to trick your brain by creating an immersive real-life like experience.

The screen inside your headset has a minimum frame and refresh rate of 60 to mimic the real-life feel. Furthermore, you are also exposed to 100 degrees FOV (Field Of View) and a response rate of fewer than 20 milliseconds (Yeah! You heard it right) that adds up to a fascinating VR experience.

  • The Aftermath of Tracking

In mobile VR experience, accurate tracking is brought up a notch by an accelerometer that detects 3D movement, a gyroscope to SketchUp angular movement and magnetometer for identifying the relative earth position.

On the other side of the plain, headsets like HTC Vive or Oculus Rift, use a system called 6DoF (six degrees of freedom) to plot your head movement in an X,Y, and Z 3D space. Furthermore, cameras and sensors can be installed in the room to track your motion.


VR field is booming as it’s unlocking new thoughts to derive the market and take our vision to a whole new level.
