what is ar and vr technology

ar and vr are two different virtual technologies. ar is the abbreviation of "Augmented Reality", which means augmented reality technology. vr is the abbreviation of "Virtual Reality", which is virtual reality technology; ar is a virtual digital screen. It is combined with naked-eye real-life images, while VR is composed of purely digital images.

What is AR and VR technology

AR and VR are two different virtual technologies. AR (Augmented Reality) is an augmented reality technology, which is a combination of virtual digital images and naked-eye reality images. VR (Virtual Reality) is a virtual reality technology consisting of pure virtual digital images. The following is a detailed description:

1. VR (Virtual Reality) Virtual reality technology allows users to immerse themselves in a computer-generated three-dimensional virtual environment and isolate it from the real environment. Take HTC's VIVE helmet as an example. Users can see a virtual interface (similar to online games) by wearing the device, and all operations can be performed without the need for real-life images. This is equivalent to a deepening of the perspective of browsing information on a traditional screen. Currently, VR is mainly used in military simulations and virtual games.

2. AR (Augmented Reality)Augmented reality technology can add or remove interactive virtual objects or information generated by computers in real time in the real environment. Take Apple's ARKit as an example. This tool suite provides developers with the ability to develop applications that serve real-life scenarios, such as rangefinders and AR games. Users can add virtual objects or information to the shooting screen through the mobile phone screen to achieve virtuality and reality. combination of images. At present, AR is mainly used in military and enterprises.

The difference between ar and vr:

1. The technologies used are different

ar includes It incorporates new technologies and methods such as multimedia, three-dimensional modeling, real-time video display and control, multi-sensor fusion, real-time tracking and registration, and scene fusion.

VR is a collection of simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensing technology, network technology and other technologies.

2. Different principles

The basic idea of ​​ar is to add images, sounds and other sensory enhancements to real-world environments in real time.

VR uses computers to generate a simulation environment. It is a system simulation of multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior, allowing users to immerse themselves in the environment. The main principle is to build a virtual environment.

3. Different functions

AR technology must be combined with reality. It has low intelligence, cannot interact with humans and computers, and cannot make people forget reality;

VR can realize human-computer interaction, has multiple perceptions, and can completely immerse people in the virtual world.
