Virtual Reality is a computer-generated 3-dimensional simulation of a game or environment, that can be interacted with using special equipment. 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 to name a few. Virtual Reality is only a type of technology, that involves altering reality and creation of a virtual environment, there exist other types 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, All of these together are known as [https://en.wikipedia.org/wiki/Extended_reality Extended Reality (XR)].

#To adjust the distance between eyes, locate the small adjustment dial on the lower-right side of the headset's display. With the headset on your head, turn the dial in either direction to adjust the distance between eyes. The exact distance modified will be shown on the HMD screen when the system is on. Adjust until image is visually clear.

=== What are VR headsets?===

A VR headset is a fully immersive device that is worn on your head; the device contains multiple sensors such as the gyroscope to help calibrate the movement in the simulation with your actual movement. There is a few different types of headsets:

Line 70: Line 79:

Tethered headsets are used in collaboration with another device such as a PC or gaming console. These headsets act as the screens and sensor for the simulation however the actual image processing occurs within the external device. You are also able to get very basic VR headsets that can be used with your smartphones screen to create a virtual Environment.

===Other VR Devices===

Over time many various other devices have been created that allow you to interact with a VR simulation, for example, there are controllers shaped like weapons that interact with first-person combat games, additionally there are also vests that simulate sensations occurring in the simulation via vibration or temperature.

===Uses for VR ===

VR is becoming increasingly 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.

[Accessed: 23-Aug-2022].</ref> Furthermore, overtime more companies have begun using VR to demonstrate their product in order to allow their consumers to have a better understanding of the products that they will be using.

===What is Steam?===

Steam is an online gaming library; it allows you to get access to and purchase various games that can be played on the PC. Many free and paid games can be found on the platform for you to use. Because using a VR headset requires the system to output the video to the headsets in a specific manner, SteamVR is used to play the VR games through your PC. The application is compatible with the HTC Vive, Oculus Rift and etc.,

There are other softwares that can be used with the VR headset such as Littlestar, VRWorks, G2 Deals and etc, which software you would use is dependent on a few criteria, such as what kind of experience do you want from virtual reality, and if you would like to consume or create content.
