Apple patents glasses-less 3D projection

I've always loved Apple's sense of design, everything from their computers to their portable devices. Now it seems that they also care about how you look by designing a 3D projection systems which doesn't require you to wear those dorky plastic glasses to view 3D content.

Apple has been granted a patent on a method of projecting a 3D image that can be viewed without glasses.

How does the system work?

A three-dimensional display system provides a projection screen having a predetermined angularly-responsive reflective surface function. Three-dimensional images are respectively modulated in coordination with the predetermined angularly-responsive reflective surface function to define a programmable mirror with a programmable deflection angle.

The previous paragraph is taken from the abstract description from the patent which doesn't make much sense. Here's my try to translate it to English:

The simplified explanation would be that the system would bounce each pixel on the screen using a reflective and textured surface directly into each of the viewers eyes creating a stereoscopic image (3D image). The system includes sensors which would locate the eyes of each viewer in order to know where to send the pixels. This will allow multiple viewer at different angles to experience the 3D content.
