Over the years, the human imagination has given way to thousands of new technologies, one of which being the creation of virtual reality technology. According to NASA, virtual reality is "the use of computer technology to create the effect of an interactive three-dimensional world in which the objects have a sense of spatial presence" (2008). The first ever virtual reality technology to be invented was done so by a man named Morton Heilig, also known to be the father of virtual reality, when he developed a machine, the Sensorama, that allowed the user to go on a virtual bicycle ride (Mihelj, Novak, & Begus, 2014). In the Sensorama, the user sat in a machine where a three-dimensional city was displayed around them, and they could also hear the sounds of the city and feel the wind and vibrations of the seat (Mihelj, Novak, & Begus (2014). While the Sensorama was never commercially successful at the time of its invention, virtual reality technology has progressed leaps and bounds since then. .
This new technology has been noted as one of the most new and promising technologies to date and has numerous uses that are applicable to many different aspects of society (Yang, Chen, & Jeng, 2010). Over the years, since virtual reality technology has been invented, the way it is used has greatly progressed. Today, those using virtual reality technology do so by using different devices such as head-mounted displays, helmets, glasses, trackers, or sensors (Yang, Chen, & Jeng, 2010). The way that this virtual reality works is that the device uses computer vision technology, which uses a camera that detects the user's motion. A video signal is then displayed onto a screen, allowing the user to interact with the new reality that is being projected (Yang, Chen, & Jeng, 2010). There are also two primary requirements of virtual reality technology, according to NASA. The first requirement is that the scene must be re-rendered from the users point of view while they move around in the virtual world, this must happen at a minimum rate of ten frames per second (NASA, 2008).
