Virtual Reality Basics

As the name says the definition itself; it is the combination of terms "virtual" and "reality". So you can define Virtual Reality, which is abbreviated as VR as means of experiencing things that exists in real but through the use of digital medium such as computer, which exists virtually. You can experience real world entity virtually in a three dimensional form. So the phrase “virtual reality” essentially means “near-reality” but not real. This is basically refers to a precise type of reality emulation that needs special devices to experience them.

We can experience different things of the world using our senses as well as insight or perception systems (provided by human body). You all might have learned about the five senses (and sense organs) in your school days: taste (using our tongue), touch (sense through our skin), smell (using our nose), sight (using our eyes) and hearing (through our ears). These obvious sense organs though help us experience the different scenarios and different situations of our surroundings. But the reality is that, there are many more senses than these five, such as a sense of balance, sense of fear etc. Technology spotted the basic 5 sensory systems along with these other sensory inputs, plus some special doling out of sensory information through our brains ensuring that our brain can transmit and receive as well as process a rich stream of information from our surrounding environment to our minds.

Everything that you have experienced till date in your life has direct connection with our senses, even the article you are reading is processing visual and eyesight. Alternatively you can say that, our complete experience of reality is merely a amalgamation of sensory data in sequence. This human feature is what Virtual Reality devices targets and gives us a virtual image of real life scenarios that we might have imagined. Let me give a scenario, where you might though of seeing the outer space and various celestial objects standing from the outer space only. But as you know it is not possible in reality. But yes, Virtual Reality made it possible to stand on some point outside the universe or in one of the wing of spaceship and nod and move your head to see each celestial object in three dimensions.

Special applications need to be built using game engines or other 3D software development applications and integrate them with VR (Virtual Reality) with the help of some APIs and drivers.

Various useful applications of Virtual Reality in different fields of science & arts are as follows:

  1. Virtual Reality in the Military, where training with guns for firing or assembling guns are being taught virtually using this trending technology.

  2. Virtual Reality in Education, helps taught different complex subjects like molecular chemistry, and biological complex creature structure in three dimension, which makes student understand it better.

  3. Virtual Reality in Healthcare, helps in diagnosis of patients and their complex human problems. Moreover doctors and researchers can map organ structure virtually and study and experiment various parts which make visualizing complex cases easier.

  4. Virtual Reality in Entertainment, is the most trending because people now a days like to watch virtual reality movies and want to play interactive games which is a booming field in the world of technology.

There are various other applications of VR with different sub categories and amazing features, which we can discuss in our later articles.
