What is AR technology and what products are there?
AR technology, which means reality enhancement technology in Chinese, is a technology to calculate the position and angle of camera images in real time and add corresponding images, videos and 3D models. The goal of this technology is to put the virtual world in the real world on the screen and interact with it.

With the popularity of AR technology, more and more AR derivatives appear in the lives of ordinary people, such as the early education product industry. The integration of AR technology has brought new experiences and interactions to children. AR popular science books look at dinosaurs, AR toys, ever-changing theaters, history and culture, AR Journey to the West, etc.

Working principle of AR technology:

1. The basic idea of the early prototype of mobile augmented reality system is to add sensory enhancement functions such as images and sounds in real time in the real world environment. Sounds simple. That's right, but what the TV network does is to display still images, which can't be adjusted with the movement of the camera.

2. Augmented reality is far more advanced than any technology you see in TV broadcast, although the early versions of augmented reality first appeared in TV games and football games, such as Racef/x and the first added offensive line, which were created by SporTVision.

3. In various universities and high-tech enterprises, augmented reality is still in the primary stage of research and development. Finally, perhaps by the end of this decade, we will see the first batch of augmented reality systems put on the market in large quantities. One researcher called it "2 1 century walkman".

4. Augmented reality should not only add images to the real environment in real time, but also change these images to adapt to the rotation of the user's head and eyes, so that the images are always within the user's visual angle.
