Introduction Virtual reality is a virtual environment that is created to try to simulate reality. Its intent is to allow a person to enter a different “world” of 3-Dimensional space. There are different types of virtual reality, which are coordinated by seven different categories of virtual reality: Immersive First-Person, Augmented Reality, Through the Window, Mirror world, Waldo world, Chamber World, and Cab Simulator Environment (Jonassen, David H.). While all types have validity in their practices, Immersive First- Person systems stand out when people think of virtual reality. Immersive First-Person focuses on putting the person in a first person view inside the images, which are made to look real in the realm of visual perception. Several systems already exist and more are currently being designed to simulate this fully immersive environment, along with interface and input devices to make the simulation even more realistic. This technology can be used in multiple fields and research, including combat training or medicine. Systems One of those systems that exist already is the head-mounted display (HMD). The head-mounted display comes in many shapes and sizes but is basically headgear, consisting of a large helmet or a pair of goggles that envelop your entire scope of vision, blocking out any sight of actual reality. There are three different ways that a 3-dimensional video format can be produced. One option is that the headgear contains two small screens (one for each eye), which display slightly different images based on what that eye would be seeing in reality. Secondly, the headgear can have one screen that combines the two video feeds for each eye and alternates the video feeds in consecutive frames. The third approach is... ... middle of paper ... ...sured amounts. Since it is virtual reality, the patient feels like they are actually facing this fear but they know there is no actual danger (Yang, Heewon). These are just some of the many possibilities for this technology, and the possibilities will continue to grow as the technology advances. Conclusion Although advances have already been made in vision and sound capabilities in virtual reality, virtual reality will continue to grow, and should eventually be able to envelop all the senses including taste, smell, and touch. As time moves on, the images that these virtual realities will be able to show will definitely increase in sharpness and clarity. Movements will be tracked more rapidly and realistically. With such a promising future, virtual reality will gain quality while at the same time becoming being cheaper, more portable, and increasingly sought after.
