When comparing VR to AR, it’s fair to claim that the latter gives alphanumeric, symbolic, or graphical information based on real-time surroundings.
Unlike virtual reality, augmented reality does not replace the real world. Instead, it uses computer vision, mapping, and depth tracking to enhance the surroundings with 3D digital objects.
These elements are spatially contextually and intelligently aligned, correlated, and stabilized. AR is being used to supplement displays, such as those seen in smart glasses and mobile AR devices such as tablets and smartphones.
These devices combine real-world surroundings with a computer-generated 3D image using onboard cameras.
Virtual reality, on the other hand, refers to display technologies both worn and fixed, that provide users with a compelling visual sensation of presence or immersion within a 3D computer simulation (a 3D model.)
This experience is made possible by the use of stereoscopic head-mounted displays and semi-immersive projection-based systems such as virtual domes.
