After wearing a VR headset for a while, you may notice symptoms of eye fatigue, and the reason is actually related to the little-known neuroscience phenomenon of vergence-accommodation conflict.
In short, the distance between the eye and the object does not match the focus. Most VR goggles require you to stare at a screen only a few centimeters away from your eyes, but focus on a point farther away. This task confuses the brain, which is used to both being in the same place. But now optical engineers have developed a new type of 3D display, a breakthrough they claim will resolve the vergence-accommodation conflict.
Liang Gao from the University of Illinois in the United States said: "We hope to replace the current optical display models used in AR and VR with our 3D display to solve the problem of eye fatigue. A new generation of 3D displays."
The new outdoor led display panels module is only 1 by 2 inches, but it produces depth cues that allow the brain to perceive in the same way as real life.
Benvenuto!
