It uses computer to generate a simulation environment, which is a multi-source information fusion, interactive three-dimensional dynamic scene and entity behavior system simulation, so that users are immersed in this environment.

Augmented reality technology (AR)

Augmented Reality (AR) is a technology to calculate the position and angle of camera images in real time and add corresponding images. The goal of this technology is to put the virtual world in the real world on the screen and interact with it.

This technology was first put forward in 1990. With the improvement of the computing power of portable electronic products, the application of augmented reality is more and more extensive.

Moreover, as far as the current market is concerned, the better VR device is HTC VIVE device, and its development prospect is also optimistic.
