What is Virtual Reality? The Future of Artificial Environment
Virtual Reality or in short what we call is VR is simulated experience taking place in an immersive environment. From immersive here we mean is the virtual environment.
Virtual Reality is a type of artificial environment where a person what he or she wants to view. We’ll elaborate on it more in the later sections.
This virtual environment can be similar to the real world or can be a whole new different experience.
Virtual Reality has its applications in various domains which you will learn later in this blog.
Currently, VR technology uses “VR headsets” and simulated or “multi-projected environment”. Using this, it generates realistic images, sounds, and various other sensations.
These sensations simulate the user’s physical presence in that environment.
These effects are created with the help of VR headsets. Headsets consist of a head-mounted display in front of the eyes.
Moreover, these effects can be created in specially designed rooms.
VR generally uses audio and video feedback and moreover uses sensory and force feedback too with the help of haptic technology.
Sounds crazy, right? Well, there is a lot more to be explored. Let’s deep dive in the topic.
Let us first have look at the history of the VR industry.
History of Virtual Reality
The history of virtual reality can be traced back to the late 20th century when Morton Heilig built “Sensorama” in 1962.
Sensorama was a mechanical device that can engage multiple senses (including sight, sound, smell, and touch) while displaying the content.
Heilig also developed “Telesphere Mask”. It was able to provide the complete sensation of reality.
Moreover, it provided the movement of 3-dimensional images with peripheral vision, binaural sound, smell and air breezes.
Dating back to 1970-1990
As you guys can guess, VR technology is quite new for our generation so it is easy to guess that it won’t have much impact in that period.
Moreover, the VR industry mainly provided its technology for flight simulation, automobile industry design, and military training purposes.
The major contributor to this industry was Jaron Lanier, who founded the company “VPL Research” in 1985. The company developed gadgets like DataGlove, the EyePhone, and the AudioSphere.
Moreover, the Power Glove, developed by “Mattel” became an affordable VR device of that time.
The decade of 90 saw the greatest advancements in the VR industry. As the semiconductor industry was transforming at a rapid rate, it boosted the development of VR.
The decade saw a widespread release of consumer VR headsets.
The gaming giant of that time, “SEGA” also came up with a virtual environment for arcade games and the Mega Drive console.
Moreover, “Virtuality” became the first mass-produced multiplayer VR entertainment system. The system became prominent in many countries.
The decade 90 saw a race between many gaming giants including SEGA and “Nintendo” to adapt VR gaming and make the best out of it.
21st Century onwards
The 21st century a huge advancement in VR technology. This advancement was this time directly related to investment in the existing VR technology to make it better.
Many companies including “SAS Cube” came up with the first PC-based cubic room. Moreover, companies like Google came up with “Street View”.
However, the biggest advent can be seen in 2010 when Palmer Lucky came up with a prototype of “Oculus Rift”. It was basically a VR headset that has a 90-degree rotational field of view.
Since then, a huge number of companies jumped in the competition to provide better VR experience to their consumer.
Moreover, VR technology has become affordable and easily accessible to most of its consumers. Also, In 2014, “Facebook” bought Oculus VR for $2 Billion.
A list of tech giants providing VR headsets are as follows:
- HTC Vive by HTC.
- PlayStation VR by Sony.
- Oculus Rift by Facebook.
- Gear VR by Samsung.
- Cardboard by Google.
- 360 VR by LG.
- Daydream by Google.
- Hololens by Microsoft.
- Sulon Q.

MUST-READ: What are the Benefits of Virtual Reality?
Let us discuss the technical aspects of VR in brief.
Technology used in Virtual Reality
The technology of VR content is quite complex. However, we will try to keep it simple as much as possible.
So let us first discuss the software used in VR content.
The initial software VRML (Virtual Reality Modeling Language) came into existence in 1994. It minimized the dependency of virtual worlds on headsets.
However, in 1997, Web3D came into existence which was used for the development of a web-based 3D environment.
Moreover, the same company came up with X3D which was based on VRML Framework. However, it is an open-source platform and free to access on the internet.
Let us now discuss the hardware requirements of a VR gadget.
Nowadays, VR devices are based on technology which is compatible with the flagship smartphones. These include gyroscopic and motion sensors for tracking body motions.
Moreover, the hardware includes HD screens for the super dynamic display which requires small and fast processors.
Omnidirectional cameras help in capturing the VR images and Videos. It captures a 360-degree view for the viewer.
However, these videos are quite large in size so they are available in either low quality or highly compressed files on the internet.
The hardware of a VR device is basically a head-mounted display (HMD), which consists of high quality of lenses. However, the quality of the lens depends upon the technology used.
Shutter Glasses are used as a part of Active technology whereas Infitec (or polarizing filter) are used as Passive technology.
These lenses basically display the two images from different perspectives to create an immersive environment.
To provide input to the system, the user is provided an optical tracking system. These are infrared cameras. They generate the location and navigation of the user.
Moreover, these input devices consist of a 3D mouse, Wired Glove as motion controllers.
Some advanced sensory devices provide force feedback so that the user can orient himself with the 3-D world through the means of haptic and sensory technology.
In its initial years, the shooting of VR content was quite a tough job. But with the advancements in technology, VR cameras are available in the market with a variety of lenses.
Now it is time to look after the various segments in Virtual Reality. Let us find out which one seems to be more appealing and interesting.
