We can call Virtual Reality an artificial three-dimensional environment created by a computer where the user observes the surrounding environment as if it were real.
Many of us like to imagine ourselves there when we come into contact with various animation movies or 3D games, and it may never be possible to fly in space or see wild animals in reality. But for this virtual reality, your feelings will be like reality. Technologists are working to develop this technology.
What is Virtual Reality?
Virtual means unreal, and Reality is reality. Virtual Reality means an artificial environment created with computer software and hardware that does not exist in reality.
Virtual reality was first used in the mid-1980s. Moreover, before that, it was used as a twin mirror. At one time, Jaron Lanier named it virtual reality, and later, it was developed by many others.
Virtual reality devices
- Data glove on hand
- Body suit
- Head-mounted display on head
Elements
- Effector: Data glove on hand, body suit and head mounted display on head are used as effectors to connect with virtual reality.
- Reality simulator: Reality simulator provides sensory information to the effector. Various sensors work as reality simulators.
- Application: Simulation software is used as an application.
- Geometry: Provides information about the external characteristics of virtual reality.
How many types of virtual reality can there be?
Virtual reality can generally be of 5 types. For example:
- Fully-immersive: This artificial environment is created to get a sense of the unimaginable world of nature and environment. As a result, you can fulfill your desired dreams, such as seeing whales under the sea and flying from one place to another in the jungle like a tiger.
- Semi-immersive: Semi-immersive is created through Fully-immersive and Non-immersive. You can control the characteristics of the character through the computer and with the help of the mouse.
- Non-immersive: An Artificial environment is created through software. You can use non-immersive as a medium for playing animation or games.
- Augmented reality: You may see some cartoon characters in a series that can give you a clear idea about that. Currently, its use is more common on TV. Or, if you want to buy some product but want to take a view of it in advance, then augmented reality can be used.
- Collaborative VR: This environment is created with advanced technology. Usually, a few people can come together to participate in this virtual project. PUBG game is now one of the popular games that is being run with the help of collaborative VR.
Use of Virtual Reality
- Air Force combat training, Navy submarine operation, and how to prepare them yourself are being done through this virtual environment.
- Teachers share their teaching virtually with students with the help of projectors. In this, they are able to learn everything in a practical way.
- Virtual reality currently occupies a huge place in the medical field in complex surgeries or diagnosing diseases.
- Virtual reality is widely used in creating graphics or in various game software. Virtual reality can bring a kind of dimension to an unrealistic environment.
- Virtual reality can also be used to check the quality of production.
- In engineering and research work, 3D images of computers are being used through simulation.
- Virtual reality has gained popularity as a medium of sports and entertainment.
Harmful effects of virtual reality
With the help of virtual reality, technology has improved a lot, but it is also having a bad effect on children.
- Children are becoming addicted to games day by day. They may have eye problems, and their corneas may also be damaged. A type of game software called Blue Whale created fear among people. Many children have even lost their lives due to addiction to this game.
- People are becoming more addicted to the world of imagination.
In my opinion, the anxiety that virtual reality has created among you has created a digital divide in technology. Since virtual reality is very expensive, it is not possible to use it according to its needs. Many more inventions in this digital world are increasing the demand for technology. But you should not forget that this is a completely imaginary existence. So use virtual reality in moderation. I hope you have got some idea about virtual reality.
