Researchers from Shanghai Artificial Intelligence Laboratory and Fudan University have together invented a new generation of glasses-free 3D display technology, the EyeReal.

For the first time, it achieves ultra-wide range full parallax glasses-free 3D display at desktop-level size, making "viewing freely without dizziness" a reality. The human eye can perceive a three-dimensional world because objects reflect light in all directions. When these light rays enter the eye, the brain automatically "synthesizes" a sense of stereo perception. The core of glasses-free 3D is to enable the screen to simulate the "all-direction light emission" effect and reconstruct a complete light field.

However, the problem is that the amount of light information required to simulate "all-directional light" is extremely large, while the information transmission capacity of modern optical display systems is limited. This makes it impossible to achieve large size, wide angle and visual continuity simultaneously.

The research team adopted a hybrid technical approach of "light field generation modeling plus neural network decoding," which is equivalent to equipping glasses-free 3D with an "intelligent brain" through AI technology.

The high-precision sensors on the screen act like "trackers," constantly monitoring the user's eyes in real time. Whether the user is sitting, standing or moving, the positions of both eyes can be instantly locked. The AI algorithm functions as a "supercomputer," capable of calculating the most suitable light distribution for the user's current position in real time and precisely sending it in the direction of both eyes, without wasting a large amount of light information on other directions.

This technology is expected to drive the integration of intelligent large models into the real physical world on a comprehensive scale. In the medical, educational, automotive and the entertainment fields, it is expected to provide a comprehensive upgraded experience.
