What is Virtual Reality?

Everyone is talking about Virtual Reality. It is definitely The Next Big Thing. But the million dollar question is what is Virtual Reality to most of the people. We present to you in simplest terms what is virtual reality and how we all can make best use of it. Don’t worry it is not as complicated as it appears.

Since the launch of smartphones, we all have seen various innovations, some new and some just an add-on. After almost a decade, we have a new technology on the horizon that promises to be completely new. Virtual Reality seems to have the potential to revolutionize the technology world as well our interaction with technology.

If that is the kind of potential it has, then what is virtual reality? By now you must have heard about Oculus. If not Oculus then at least the Samsung Gear VR.


Virtual Reality as defined by Wikipedia is,

Virtual Reality refers to the computer technology that uses software to generate realistic images, sounds and other sensations that replicate the real environment.


What is VR in common terms or VR for Dummies?

Opinions differ on what is pure VR. However, for us mortals the basic definition should include,

  • Three-dimensional images that appear to be life-sized from the perspective of the user
  • The ability to track a user’s motions, particularly his head and eye movements, and correspondingly adjust/display the images on the user’s interface to reflect the change in perspective

So a life sized 360 degree image presenting and processing device, such as a mobile along with a VR Headset should be able to provide you the VR experience.

But hold on…. Is that enough or there is more to it than simply grabbing a smartphone and a VR device? Unfortunately no….


VR Compatible Smartphone



What you need is a VR compatible phone. Well a VR compatible smartphone takes care of the second point while the VR Headset provides the life-size view of the tiny little 360 degree images coming from mobile.

A VR Compatible phone has to provide an immersive experience to the user. It has to replicate and match the body movement of the user and change the perspective accordingly.

For example, when we are in a room and as we turn around, we see different areas of the room. Similarly, when you have a VR smartphone in a VR Device and you move around, it will make you feel as if you are standing inside the room by changing the view of the room in exact same manner.

What you need to look for in a smartphone are some basic sensors which are key for VR Compatability.

  • Magnetometers – A device which measures the magnetic field and can tell you which direction you are facing with respect to North pole. Magnetometer in a smartphone is used by some VR Headsets to use as a button click.
  • Accelerometer – It tells the smartphone whether you are facing up or down.
  • Gyroscope – Helps the smartphone to understand the orientation at a tiny level.

Check your smartphone for these sensors on GSMArena to find out if it is VR Compatible.
