Apple has applied for a patent for an "automatically adjusting media display in a personal display system," a kind of head-tracking eyewear that gives the user "the impression of being in the theater."
From the claims of the patent, the device looks not unlike a pair of goggles that display a cropped version of a larger media file. As the wearer moves his or her head, a gyroscope and accelerometer in the goggles adjust the crop of the media file, making it appear to the user as if they were in a theater-like experience.
The patent also includes provisions for techniques to reduce eyestrain, determine when the user reaches the "edge" of the media file, and zoom in and out.
The application was prepared in February, and its number is 20080276196.
