Virtual Reality - Introduction
Last Updated : 15 Apr, 2025
Virtual Reality places the viewer inside a moment or a place, made possible by visual and sound technology that makes the brain into believing it is somewhere else. It is an experience of a world that does not exist.
Sounds cool, right?
Virtual Reality tricks one’s mind using computers that allow one to experience and more interestingly, interact with a 3D world.
What is Virtual Reality?
Virtual Reality (VR) is a technology that creates a simulated environment, allowing users to feel like they are in a different place or world. VR puts you inside a computer-generated world that feels real. It does this by using special equipment that covers your eyes and sometimes your ears called VR Headset. Virtual Reality creates a believable, interactive 3D environment that you can explore and interact with, making you feel like you are really there.
This is made possible by putting on a head-mounted display that sends a form of input tracking. The display is split between the eyes and thus creates a stereoscopic 3D effect with stereo sound to give you a graphic experience.
The technology feeds in the images of the objects taken at slightly different angles which creates an impression of depth and solidity. The LCD or OLED panels inside are refracted by lenses completely fill the field of vision with what is to be displayed and experienced. Together with the technology and the input tracking, it creates an immersive and exciting believable world that the computer generates. What we know today as VR, has been existing for decades now. Taking you back to when 360° paintings took the world by surprise, giving a virtual element.
VR merely is ‘The Wise Guy’ of the digital world. It creates a world that neither functions according to you, nor does it respond to your actions. It gives you a first-hand experience with even the after-effects of an event along with the ability to interact and interrelate with the world created. This technology holds vast potential insights into the workings of the Human Brain.
Types of Virtual Reality (VR)
On the basis of the most important feature of VR i.e. immersion and the types of systems and interfaces used, The VR systems can be classified into 3 types :
- Immersive
- Semi-immersive
- Non - immersive
1. Immersive VR system
Immersive VR system is closest to the virtual environment. It makes us experience the highest level of immersion. This VR system is expensive than others. It provides the closest feeling of being in virtual world. Tools and gadgets used in this system are advanced and not so common to use.
2. Semi - immersive VR system
Semi - immersive VR systems also make us to experience a high level of immersion but the tools and gadgets used are not so advanced and costly. Tools and gadgets used in this system are common to us and utilize physical models.
3. Non-immersive VR system
Non-immersive VR system is the least immersive and least immersive VR system. It is not expensive to use this system. It is also known as desktop VR system because the gadgets used are limited to glasses and display monitors and it uses the least expensive components.
What are the basic components for VR systems?
- Input devices
- Output devices
- Software
1. Input Devices
Input devices in VR are the tools for the users to interact with virtual world. Using Input devices , the users communicates with the computer.
Example - 3D mouse.
2. Output devices
Output devices is used to represent the virtual world and it's effect to the users. It generates the feeling of immersion to the users.
Example : LCD shutter glasses.
3. Software
Software has a key role in VR . It is used for the handling Input and output devices, data analysis and generate feedback. Software controls and synchronize the whole environment.

Conclusion
In conclusion, Virtual Reality (VR) is an incredible technology that creates a simulated, interactive 3D world. By using a special headset and sometimes other equipment, VR tricks your brain into feeling like you are in a different place. This technology has come a long way and can be used for various purposes, from entertainment and education to training and therapy.
VR systems can vary in how immersive they are, from fully immersive experiences to more basic ones that you can use with just a computer and monitor. The main components of VR systems include input devices (like 3D mice), output devices (like special glasses), and software that brings everything together.
Overall, VR offers a fascinating way to explore, interact with, and experience new worlds, making it a powerful tool for both fun and practical applications.
