HP to reveal 3D screen for mobile that allows users to move 45 degrees from center
45 degree angle in any direction to the screen and still see the images in 3D. HP scientists used nanotechnology to etch into the glass, multiple circles with tiny grooves. The grooves bend light into 64 points of view. As a user views the screen and moves it, he will see two of these points at one time, one with the left eye and one with the right, creating the 3D effect.
As you might expect with a bunch of scientists, especially if you watch The Big BangTheory, the discovery was put into a language that the scientific community could understand. The article's lead author, David Fattal, compared the effect to the hologram of Princess Leia from the classic Star Wars. Fattal said that the image won't pop out as much as Princess Leia's did in the movie. And speaking of motion pictures, don't expect the technique to be used for filming movies. While 3D images can be created using computer animation, to use this technique for live action would require 64 cameras pointed at the same subject.
