Virtual reality refers to a computer-generated illusion in which a person can interact directly with an artificial three-dimensional environment using electronic devices fitted with sensors. In this artificial environment created by humans, the user can have a realistic-feeling experience.
VR creates an artificial world that can seem quite real, via the use of technology. Like any virtual reality viewer, one can look up, down, or any which way he/she wants, as if they were actually there. VR can be used in many fields including entertainment and gaming, or acting as a sales, educational, or training tool.
Virtual reality is a combination of two words ‘Virtual’ and ‘Real’. The experience is near to reality but with the use of technology.
Let’s understand Virtual reality with example- Human senses includes smell, taste, touch, sight, and hearing, as well as spatial awareness and balance. Inputs gathered by all the senses are sent directly to the brain and brain makes interpretations of the objective environment around us. Virtual reality creates an illusionary environment with the use of technology. Illusions created by VR can be presented to our senses with artificial information, but our minds believe it as a reality. One of the examples of VR is three dimensional OR 3D movies. By using special 3D glasses, one can get immersive experience of being a part of the movie with on-spot presence, but reality is completed different.
Sellers of real estate also use this technique; they provide aided walkthroughs of a home or apartment to give a feel for a property without actually having to physically be present at the location with a potential buyer.
Virtual Reality applications require more than just graphics, hearing and audio is also taken into consideration. Audio plays a very important role; humans react better to audio and visual appearances. VR can be used almost in every field including education, healthcare, military, sport, mental health, medical training, and fashion.
Some of the top brands in the world have VR in their marketing strategy to keep them up to date–and it’s no wonder because it’s one of the powerful marketing tools. Virtual reality is the generalized term used for any type of experience that essentially places the user “in” another world (you can even call it imaginary world). It may be used in reference to digital worlds, or worlds that are mixture of real and virtual.
