What is the difference between AR and VR, and what are their applications?

AR is an acronym for Augmented Reality, and its Chinese name is Augmented Reality, which is a brand-new human-computer interaction technology. Through AR technology, participants can interact with virtual objects in real time, so as to gain wonderful visual experience, break through the objective limitations of space and time, and feel experiences that cannot be experienced in the real world.

VR is a kind of virtual reality technology, which generates a simulation environment through computer technology and immerses users in the created three-dimensional dynamic real scene, which can be understood as a simulation system for the real world. The earliest VR technology was used in the military field, and the most common product was the head-mounted display.

Generally speaking, AR (Augmented Reality), seeing whether scenes and characters are true or not, is to bring virtual information to the real world; VR (Virtual Reality), the scenes and characters you see are fake, made by a computer, and immerse you in a virtual world.

Extended data:

Virtual reality is a synthesis of many technologies, including real-time three-dimensional computer graphics technology, wide-angle (wide-field) stereoscopic display technology, observer's head, eye and hand tracking technology, tactile/force feedback, stereoscopic, network transmission, voice input and output technology and so on.

Comparatively speaking, it is not too difficult to generate graphic images by using computer models. If we have enough accurate models and enough time, we can generate accurate images of various objects under different lighting conditions, but the key here is real-time. For example, in the flight simulation system, image refresh is very important, and the requirements for image quality are also very high. Coupled with the very complex virtual environment, the problem becomes quite difficult.
