What is Virtual Reality and Augmented Reality?


Virtual is defined as “near” and Reality is defined as “something we experience as humans in our lives”. So Virtual Reality means “near-reality”. It usually refers to a specific kind of reality imitation. VR is a common technology for gamers and tech lovers. Now we will talk about what VR actually is, we can understand this term wholly by looking at the name of the term itself, Virtual and Reality. 

Living in this environment as human beings we understand it through our senses i.e the sense of smell, touch, sight, hearing, and taste. These are the common basic five senses we are taught in our schools. But the human system is not confined to just these senses, it is much more than that and has many other senses too like the sense of balance, and our brain processes these senses in a special manner so that we can achieve a proper flow of information from the environment to our minds.

Whatever we know about our reality is due to our senses. Through senses, we perceive our reality and process information about our environment according to our perception. If we include our perspective in the information we get through our environment it will become a piece of reality with the hint of our ideas and be a version of reality which is exactly not real but it is considered as real by our perception. It is something we will consider close to reality and refer to as ‘virtual reality’.

Virtual Reality in technical terms means experiencing things through computers that literally do not exists, the one which a person can explore and interact. The person then becomes a part of this environment and as being in that environment the person can manipulate objects and perform certain actions.


Augmented Reality is basically connecting the real world to the virtual world i.e connecting what we experience in real to the world of virtual information we have created on the internet.


Mixed Reality is like a hybrid system, it involves the elements of both physical and virtual worlds. Many experts explain it as a sliding element between a complete physical environment and a completely virtual environment.

Mixed and Augmented reality terms are occasionally used interchangeably but still, there are some major differences.

HISTORY OF Virtual Reality (VR)

The technologies of today’s virtual reality are based on the ideas of the 1800s, which was almost the time of the beginning of photography. In 1938, using twin mirrors the first stereoscope was invented to project a single image. And it developed into View-Master eventually in 1939 and is still being produced today.

The term “virtual reality” was first used in the mid-1980s when gears were being developed including google and gloves by Jaron Lanier, who wanted to experience what he actually named as “virtual reality”.

Technologists were producing an imitated environment even before that. One example is Sensorama during 1956 created by Morton Heilig. He came from a background of the Hollywood motion picture industry. He wanted to make the people see and feel how it feels like to be “in” the movie. A real city environment is imitated in Sensorama in which you ride through it on a motorcycle. The element of Multisensory imitation lets the people see the road and hear the engine of bike, to feel its vibrations, and even to smell its exhaust in the designed “world”.

In 1965, Ivan Sutherland invented “the Ultimate Display”, a device he suggested will serve as a window into a virtual world.

The current versions of today’s virtual reality gear are no doubt bears a debt to the magnificent inventors of the past six decades, who made ways for the high quality and cheaply priced devices that are easily available today.

Advantages and Disadvantages of Virtual Reality

Virtual Reality also has both positive and negative aspects like any other technology. How many of us will prefer brain surgery by a surgeon who is trained in VR to a person who has just read books and watched his peers doing it? How many of us will rather practice on a car simulator before we actually step on the road?

A point is always raised by critics that the people often neglect their real-world lives just because they are so engrossed in an alternative reality, but actually VR takes equal to nothing from the real world; you don’t have to use the virtual world if you don’t want to because it’s not a compulsion.

Virtual Reality can be used on a positive side like recording histories in a way that they can be revived again and again by the students, instead of just sharing your photos and information over the social media what if you actually make your friends attend your parties and ceremonies virtually? If it is so then with no doubt, the future of Virtual Reality is very bright.



HTC Vive is one of the best VR Headset in the market since it was released in 2016 by its consumer. It is manufactured by HTC and is the first VR HMD which supports StreamVR. Aimed at the same top end of the VR market, the HTC Vive and Oculus Rift are both engaged in a serious competition since its release. The HTC Vive has proved itself a reliable workstation for the enterprise solutions and it also delivers the best consumer VR experience available. The HTC Vive was firstly released in 2016 and it has gone through multiple duplications and has also come up with the addition of wireless modules. The HTC Vive Pro was released in 2018 and the HTC Vive Pro Eye and the HTC Vive Cosmos are both set up to be released in the second half of 2019.
