Virtual reality in technical terms is a 3rd dimensional computer generated environment. It can be used by a person, as a person explores the virtual world. The user can manipulate things or perform actions.

Virtual Reality

Virtual reality is also a computer technology that replicates a real environment and also allows the user to interact with the environment. Virtual reality allows the user to move around and perform other actions in the virtual world.

The History of Virtual Reality

The idea of this system came from the short science fiction story called the Pygmalion’s spectacles. the story was created by Stanley G. weinbaum in 1935 and in the mid 1980s was popularized by Jaron  lainer who own the VPL research company.

Morten Heilig created the sensorama in 1962 in the year 1968. Ivan Sutherland and his student Bob sproull created the first virtual reality head mounted display HMD. But the HMD was too heavy to be worn by a user so it had to be suspended on the ceiling.

Battle zone, an arcade video game in the 1980s used 3D graphics to engross the player into the virtual world. Virtual reality wasn’t really popular although it had media coverage in the late 80s. But movies like Brainstorms and lawnmover man help popularize the virtual World concept in 1991.

Sega launched the Sega VR headsets for an arcade game and Mega Drive console. Then oculus VR created the Oculus Rift, then a year later facebook bought Oculus VR for US$2Billion. In 2015, HTC allied with valve corporation to launch their virtual headset.

How Virtual Reality Works

In the VR world, a user experiences a feeling of being a part of a world. He or she we be able to talk with his or her environment in a lot of ways. The additional sense of immersion and interactivity is called ”Telepresence” for immersion to be successful. The user must be able to discover what appears to be a life sized virtual environment and be able to change perspective seamlessly.

Areas Where Virtual reality Can be Used

Video games

Oculus Rift is an HMD head mounted display for playing games. It allows the user to enjoy gaming pleasure, in 3D, it is also full in HD high definition.


Virtual reality adds more aspect to virtual modeling. Such as product creation, assembly, service, and performance. It allows engineers to view it in the final product, engineering allows management and investors to observe virtual prototypes prior to the accessibility of any material prototype.

Education and Training

Virtual reality is used  by trainers to offer the learner a virtual environment, in order for them to develop their skills without the consequences of failing, an immersive virtual reality that uses the HMD (head mounted display) Data suits, Data gloves, and VR weapons assist soldiers to train through a vast number of different terrains, situations and scenarios.

Medical practitioners have the capability to familiarize themselves with quite a number of skills in a corrective environment.

Why we Need Virtual Reality

Virtual reality seems like a large effort, but it’s worth it because it helps us, humans, to do a lot of things without risking the life of the user. Although, the user needs to use his or her imagination navigate in the virtual world. It could lead to amazing discoveries that make impact our lives.

Virtual reality is the construction of a virtual environment offered to users in such a way that we experience it as if we were really there. The technology is getting better cheaper and more popular. A scientist can create many inventions with the help of Virtual reality.
