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 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 glasses can be used.

The Oculus Rift system is a VR head-mounted display (HMD) system that is owned by Facebook Inc. The Development Kit 2 was introduced in 2014 and allowed developers to begin creating applications prior to the official release of the Oculus Rift system. The DevKit2 only supports positional tracking in the form of head movement within a small radius and does not provide controllers or remotes to allow users to interact with their environments.

The HTC Vive is a full room-tracking VR system that includes one HMD, two handheld controllers, and two (or more) lighthouse base stations to track user positional data. The system was released in 2016 and became a very popular system due its robustness and immersive experience. The system was developed by HTC and Valve Corporation, and thus a developer package was released by Valve coined "SteamVR" to allow developers to create applications on the headset using the Unity game engine.

The headset has a 1080x1200 (per eye) resolution, a 90 Hz refresh rate, and a 110-degree nominal field of view. The headset also supports users wearing non-bulky glasses while playing by adjusting the headstrap, focal distance, and eye distance.

#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.
