Naked-eye 3D displays, even large-sized models, are nothing special anymore, but they usually have a common problem: the 3D effect when viewing pictures isn’t as strong as with displays that require users to wear glasses. Professor Kakeya from Tsukuba University in Japan is trying to solve the problem.
The way his 3D display works is actually pretty simple: it uses multiple layers and lenses to boost the sense of depth perception. Professor Kakeya explains:
It forms images of objects at the front toward the front, and objects at the back toward the back. When objects at the front are in focus, those at the back are blurred, and when you’re looking at objects at the back, those in front are blurred. So a feature of this display is that it reproduces focal depth.
The resolution in the current prototype stands at just 200×200, but another cool feature is that it allows you to view pictures in 3D not only when you move your head horizontally, but also when you move it vertically.
