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. Some examples would be AR doodle, AR emoji camera or even Google AR.

Some applications of AR would be AR doodle, AR emoji camera or even Google AR.AR is a combination between the real and virtual world, but there is no interaction between them whatsoever. This is in fact the primary difference between AR and MR.

# To adjust the focal distance between the lenses and screen, locate the two mount points on either side of the headset (where the straps meet the display body) and pull the two gray dials outward. Once you've done so, turn both dials simultaneously either forward or backward until the image appears clear.

# 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.

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:

==== Standalone====

====Standalone====

Standalone headsets are able to work independently of an external device such as a PC or gaming console. They have their own system that is able to power and run the simulation.

==== Tethered====

====Tethered====

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.

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.

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.,
