Acutally I don't know how to name the term, so I just call it Ocular TV. The idea is exactly emulate the light source from distance. Instead of 2D image on the screen, it emulates the real world light source where you need to focus your eyes to see the object in the screen. The refresh rate would have to be 10 times higher to emulate approaximately 10 times of depth level. So in a still image, you can see the clear water drop on a window or you look further and see the blurry water drop and clear street light from afar (good eyes required).
It doesn't need 10 time of rehresh rate if you can display 10 depth of light sources in one refresh. But, I am sure there needs to be a balance to emulate more depths than the limitation of equipements. The light is only clear at certain focal point for each depth. So, instead of depth of feild blur in 3D games, there is no need for artifical blurring anymore. It is a clear picture with z info where such pixel will be clear at certain focal point.
In a sense, this is the real 3D display where things are 3D inside deeper into the display instead of a fake 3D that are poping out of screen. I mean seriously, only ghost would pop out of a window. The world you see beyond a window would never pop-up except the fake optical illusions.
What do you guys think? Is this doable with our current technology? It will be a shoot lights out approach with about 10 layers of focal point, and maybe double the refresh rate to double the depth layers.
