This is a United States patent that describes a device capable of conveying a magic window effect, where the user is able to see through the device and into a perspective corrected augmented reality environment.

(Abstract) Systems and methods are disclosed for generating an image for a user based on an image captured by a scene-facing camera or detector. The user's position relative to a component of the system is determined, and the image captured by the scene-facing detector is modified based on the user's position. The resulting image represents the scene as seen from the perspective of the user. The resulting image may be further modified by augmenting the image with additional images, graphics, or other data.
