What does VRAR mean?

VR refers to virtual reality technology, a computer simulation system that can create and experience a virtual world. It is actually a computer system that can create and experience a virtual world.

AR refers to augmented reality technology. It is a technology that calculates the position and angle of camera images in real time and adds corresponding images. It is a "seamless" integration of real world information and virtual world information. The goal of this new technology is to put the virtual world into the real world on the screen and interact with it.

The difference between VR and AR:

1. The technologies used are different

VR is simulation technology, computer graphics, human-computer interface technology, multimedia technology, and sensing technology A collection of various technologies such as network technology.

AR includes 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.

2. Different principles

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

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

3. Different functions

VR can realize human-computer interaction, has multiple perceptions, and can completely immerse people in the virtual world, while AR technology must be combined with reality , has low intelligence, cannot interact with humans, and cannot make people forget reality.
