… is already giving me a headache.
The conceit behind the patent app is a pair of glasses you attach an iPhone, iPod or similar Apple device to watch video in high-def equivalent 3D. Just imagine the neck strain of having the weight of an iPhone resting on the bridge of your nose for an extended period of time, not to mention the eyestrain.
I wonder if this patent application entered the system on April 1, or maybe Navin Johnson is now an Apple engineer.

Here’s a look at an illustration of the concept:

And here’s a little more detail:
Apple has filed a patent application for electronic video spectacles that will allow wearers to watch films in 3D on the inside of the glasses. Fans have already nicknamed the gadget iSpecs.
Users would attach their iPhone, iPod, or other device to the spectacles, which have a special lens that can split the image into two frames — one for each eye — and then project the image onto the spectacles. The two images would create a stereoscopic effect since they would appear to have been taken from slightly different angles, and this would simulate 3D.
According to the patent application (number 20100079356) the images would be equivalent to high definition in quality, and sensors inside the spectacles would detect the precise location of the wearer’s eyes to ensure the image is projected at exactly the right place and is comfortable to watch.
