The best way to understand what virtual reality means is by understanding first the terms used to coin the word itself. What does virtual reality mean? Virtual simply means near or something practical while reality is what human beings experience. Basically, thus, virtual reality means near-reality. Nonetheless, the near-reality here specifically refers to a particular type of reality emulation or impersonation. Virtual reality entails the computing fundamentals and thus it technically refers to an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment.


There has risen great confusion between virtual reality and augmented reality. With the latter, it is a technology that layers computer-generated enhancements atop an existing reality so as to make it more meaningful through the ability to interact with it. It is developed into apps and used on mobile devices to blend digital components into the real world in such a way that they enhance one another, but can also be put apart easily. It is used to display telecasted sports games and pop out 3D emails, text messages or photos on mobile devices. 


On the other hand, virtual reality is the artificial computer-generated simulation or recreation of a real life environment or situation. With virtual reality, the user is immersed by making them feel as if they are at first hand experiencing the simulated reality by originally stimulating their vision and hearing. In simple terms, augmented reality delivers virtual elements as an overlay to the real world while virtual reality offers a digital recreation of a real life setting.


Are you wondering how virtual reality healthcare works? It is naturally achieved by wearing a headset like an oculus used for Facebook-equipped with the technology. Virtual reality is used in two different ways. One it is to enhance training for real life environments by creating a simulation of reality where people can practice beforehand. A good example is the flight simulators for pilots. Another way virtual reality is used is for creation and enhancement of an imaginary reality for gaming, play, and entertainment. Examples of this include; head mounted display, video, and computer games or 3D movies.


Virtual reality works through coding language technically known as the virtual reality modeling language. The coding is used to specify what types of interactions are possible for them and also for the creation of a series of images.
