Apple Patents Glasses-Free 3-D

According to the Telegraph, Apple has been granted a patent for a display screen that will project 3-D images without the need for bulky, unfashionable 3-D glasses. (Nintendo got there first in the video-game world.) The patent application explains, "By tracking movements of the eye locations of the observer, the left and right 3D sub-images are adjusted in response to the tracked eye movements to produce images that mimic a real hologram. The invention can accordingly continuously project a 3D image to the observer that recreates the actual viewing experience that the observer would have when moving in space around and in the vicinity of various virtual objects displayed therein."
