Virtual reality, it’s how a person’s vision is simulated. It involves experiencing a three-dimensional environment within a headset. Virtual reality has been used for many purposes such as gaming, training, education, and other great things. The question is how does it function? and what makes it function? As you might have already known there is a head-mountied display and the video projected can be sent via HDMI cable from a console or computer. Virtual Reality headsets use either two feeds sent to one display or two LCD displays, one per eye. There are lenses that are able to be placed between your eyes and the pixels. For this reason some devices are called goggles.  Head Tracking is when you wear a VR headset in which the picture shifts in any direction following the movements of the head, that being up, down, left, right, or any other direction. There is also some motion tracking involved on the user’s body depending on how much of a VR experience that individual wants. There are controllers that you are used to even help the user feel as if they were using their hands in the program. For the body tracking, companies sell sensor devices that can be placed around a room that will sync accordingly to the user’s movements to match the game or program’s AI. In doing so the user will feel as if they are the character or person in the game or program. Virtual Reality has really changed the future for many gamers and others who use it in their workplace.
