VIRTUAL REALITY

virtual reality was not more than the thoughts


Until recent years, virtual reality was not more than the thoughts and fantasy for scientists and technologist. Fortunately, this has become reality from the past few years like Internet of Things and Artificial Intelligence.



HISTORY OF VIRTUAL REALITY


The term virtual reality was coined in by Jaron Lanier in 1987. Jaron is an American computer scientist and the co-founder of Virtual Reality. His research and engineering contributed a number of products to the nascent VR industry.


WHAT IS VIRTUAL REALITY?


Virtual Reality is the artificial computer generated simulated environment in which a person interacts with the artificial 3D environment using VR boxes and other electronic devices such as goggles, screen gloves and sensors.

Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences are the availability of content and cheap computing power.





TYPES OF VIRTUAL REALITY


There are generally 3 types of VR simulations:

  • Non-immersive simulations

  • Semi-immersive simulations

  • Fully-immersive simulations

Non-immersive simulations

Non-immersive virtual reality simulation is the most common type of VR simulation that it is often overlooked as a virtual reality category. This technology provides the computer generated simulations but enables the user to be aware of their physical environment. It relies on computer systems, mouse, keyboard, CPU and video game controller. Video games are the best example of non-immersive simulations.


Semi-immersive simulations

Semi-immersive virtual experiences provide users with a partially virtual environment. It will still give users the perception of being in a different reality when they focus on the digital image, but also allows users to remain connected to their physical surroundings. Semi-immersive technology provides realism through 3D graphics. This category of VR is used often for educational or training purposes and relies on high-resolution displays, powerful computers, projectors or hard simulators that partially replicate design and functionality of functional real- world mechanisms.


Fully-immersive simulations

Fully-immersive simulations are the top level simulations that give real experience to the users with complete vision and sound effects. Users have to wear VR glasses or head mount display (HMD) to have experience. This type of VR simulations are used in gaming and other entertainment industries but usage in other sectors, namely education, is increasing now as well. The possibilities for VR usage are endless.



VIRTUAL REALITY VS. AUGMENTED REALITY


These two terms are usually found next to each other but their meanings are quite different.


Augmented Reality

Augmented Reality is the advanced version of real physical world that presents the virtual objects in our natural environment. This is achieved through the use of different sensors, visual elements and sound stimuli via technology. One of the best example of augmented reality is Google Earth.


Virtual Reality

It creates a virtual environment and people move inside that environment using VR objects such as glasses and gauges. I can talk to other people, play games, or just go for a walk and enjoy the view. I can do anything I like in that environment, as long as the software has made it possible.
