The 2023 World Computing Conference kicked off in Changsha, central China's Hunan Province, on September 15th, with the theme of "Calculating the World to Create A New Era-New Changes in the Computing Industry". The list of the top ten black technologies in 2023 was released at the conference. Naked eye 3D ranks among the top ten black technologies in 2023.

Naked eye 3D refers to the technology that can achieve stereoscopic visual effects without the use of external tools. With the arrival of this technology, new media advertising has entered a new era. Major shopping malls have begun to explore the "golden potential" of 3D advertising screens. Almost every landmark building will use Naked eye 3D technology to attract more tourists.

The Naked eye 3D video technology that is widely available today actually uses the Parallax barrier technology in optical illusion. Visual illusion is simply a method of expanding and confusing spatial perception with perspective painting. Anamorphosis is a distorted projection that requires the viewer to occupy a specific vantage point and view a recognizable image using a special device or both.

The key points for making Naked eye 3D display is by letting the subject of the picture go outside the frame, people can achieve visual differences and illusions.

Another is artificial distortion of the picture, generally, naked eye 3D screens will be played at the corners of buildings. This also takes advantage of people's visual difference. Standing in front of the corner, people can see the sides and front of the object at the same time, feeling a realistic and shocking three-dimensional effect.

Google's 3D video calling booths, the Starline use naked eye 3D technology and advanced holographic projection technology, providing users with Immersive 3D communication experience. Naked eye 3D technology has broad application prospects in fields such as communications and entertainment in the future. In the future, there will be more channels to apply this technology, and it will also be integrated with more technologies to form a broader application field.
