A recently granted patent reveals that Apple, the company behind the iPod and iPhone, has been working on a new type of display screen that produces three dimensional and even holographic images without the need for glasses.
The technology could be used to produce a new generation of televisions, computer monitors and cinema screens that would provide viewers with a more realistic experience.
The system relies upon a special screen that is dotted with tiny pixel-sized domes that deflect images taken from slightly different angles into the right and left eye of the viewer.
By presenting images taken from slightly different angles to the right and left eye, this creates a stereoscopic image that the brain interprets as three-dimensional.
Apple also proposes using 3D imaging technology to track the movements of multiple viewers and the positions of their eyes so that the direction the image is deflected by the screen can be subtly adjusted to ensure the picture remains sharp and in 3D.
The patent claims this technology would also create images that appear to be holographic because of the ability to track the observers movements.
