It is a virtual world with realistic elements, sounds and occurrences comparable to the real world. The simulation is typically run on a device such as a computer, game console or smartphone, and the information is then sent to a VR headset. Upon wearing the headset, the user will be immersed in the virtual world with the ability to move around, interact with characters present and explore the vast virtual world. Nowadays, apart from game creations, VR is applied in other industries such as healthcare, automotive and tourism.  Virtual Reality is only one type of technology, that involves altering reality and creating a virtual environment, there exist other varieties of technologies such as [https://en.wikipedia.org/wiki/Augmented_reality Augmented Reality (AR)] and [https://en.wikipedia.org/wiki/Mixed_reality Mixed Reality(MR)].

Augmented Reality is the superimposition of computer-generated entities onto the physical world. Some applications of AR would be AR doodle, AR emoji camera or even Google AR. Augmented Reality is a combination of the real and virtual world, but there is no interaction between them whatsoever. This is the primary difference between AR and MR. The equipment required when dealing with AR can be most accessible since a mobile phone can be used to overlay digital entities onto the real world. Yet, for more complex tasks AR headsets or special glasses such as the [https://en.wikipedia.org/wiki/Ray-Ban_Stories Ray-ban Meta] can be used.

Mixed Reality merges a real-world environment with a virtual one, that is a computer-generated one, and the two worlds can interact with each other. Similarly to Virtual Reality, Mixed Reality requires a headset, such as the [https://www.microsoft.com/en-us/hololens Microsoft Hololens 2], to enable the exchange between the digital world and the real world to occur.

VR is becoming steadily more useful for education and training.VR trainings in medicine allow students to interact with and experience various scenarios that give them a greater understanding of a subject. Additionally, VR simulations will be used to explain complex procedures and treatments to patients in order to ease their anxiety and further their knowledge of their conditions. <ref>E.
