What is Virtual Reality

Virtual Reality (VR) technology uses a computer to create an imaginary environment. Unlike the traditional types of user interfaces, VR makes the users an excellent experience. Users submerge onto the screen and interact with the 3D worlds instead of viewing the screen in front of them. By pretending as many senses as possible, like hearing, vision, even smelling and touching, the computer transforms the users into this artificial 3D world. Computing power and availability of content are only the limits to make nearly real VR experiences.

In Augmented Reality, the computer uses many different technologies, like algorithms and sensors to define the orientation and position of a camera. Thus, AR exhibits the 3D graphics that they visualize from the camera point of view. As a result, this technology superimposes the computer-generated images over the real world views of the users. 

On the other hands, in Virtual Reality technology, the computer uses similar technologies like sensors and math. However, instead of locating a real camera physically in the user’s environment, this technology places the user’s eyes within the pretend environment. Whenever the user turns their head, the graphics also react accordingly. VR technology creates an imaginary, interactive and artificial world rather than creating a real scene or virtualized objects.
