Apple Patents Glass-Free 3D Projection Technology
Apple has just been granted a patent on a technology that can produce 3D images without the need for glasses. The basic idea behind this is that the images are projected onto reflective and textured surfaces and are then bounced back into our left and right eyes resulting in a stereoscopic effect.
There are various advantages to this technology, for one it enables users to watch in 3D without the irritation of having to wear glasses and it also allows multiple users to view the images or videos simultaneously.
This technology is also a step ahead of current glassless 3D technology as it does not require the viewer to sit in one specific spot without moving. This technology allows users to move and still enjoy the benefits of 3D.
The patent was filed back in 2006 and has just been approved. We are not sure when we can see it in their products but the idea of 3D iPhones, iPods and iPads sounds cool.
