The Ultimate Guide to Virtual Reality (VR) Technolog

Introduction to Virtual Reality (VR) 

Virtual Reality (VR) literally makes it possible to experience anything, anywhere, anytime. It is the most immersive type of reality technology and can convince the human brain that it is somewhere it is really not. Head mounted displays are used with headphones and hand controllers to provide a fully immersive experience. With the largest technology companies on planet earth (Facebook, Google, and Microsoft) currently investing billions of dollars into virtual reality companies and startups, the future of virtual reality is set to be a pillar of our everyday lives.
 A realistic three-dimensional image or artificial environment that is created with a mixture of interactive hardware and software, and presented to the user in such a way that the any doubts are suspended and it is accepted as a real environment in which it is interacted with in a seemingly real or physical way. (e.g. walking around the streets of London), or may exceed the bounds of physical reality by creating a world in which the physical laws governing gravity, time and material properties no longer hold (e.g. shooting space aliens on a foreign gravity-less planet).

Types of Virtual Reality

Virtual Reality (VR) Categories

1) Non-Immersive


Non-immersive simulations are the least immersive implementation of virtual reality technology. In a non-immersive simulation, only a subset of the user’s senses are stimulated, allowing for peripheral awareness of the reality outside the virtual reality simulation. Users enter into these three-dimensional virtual environments through a portal or window by utilizing standard high resolution monitors powered by processing power typically found on conventional desktop workstations.


2) Semi-Immersive

Virtual Reality - Semi ImmersiveSemi-immersive simulations provide a more immersive experience, in which the user is partly but not fully immersed in a virtual environment. Semi-immersive simulations closely resemble and utilize many of the same technologies found in flight simulation. Semi-immersive simulations are powered by high performance graphical computing systems, which are often then coupled with large screen projector systems or multiple television projection systems to properly stimulate the user’s visuals.

3) Fully Immersive

Fully-immersive simulations provide the most immersive implementation of virtual reality technology. In a fully-immersive simulation, hardware such as head-mounted displays and motion detecting devices are used to stimulate all of a user’s senses. Fully immersive simulations are able to provide very realistic user experiences by delivering a wide field of view, high resolutions, increased update rates (also called refresh rate), and high levels of contrast into a user’s head-mounted display (HMD).
