1. A computer-implemented method for providing an augmented reality interface, comprising:

  • preloading a plurality of image snippets from a server to a portable electronic device based on a location information of the portable electronic device, each of the plurality of image snippets being a smaller image file of a corresponding stored image;

    acquiring an image of a real-world scene with a camera, the image being one of a still photograph and a video frame;

    overlaying one or more of the plurality of image snippets corresponding to a location and a direction at which a corresponding image was originally captured based on the location information and an orientation information of the portable electronic device without manipulating the plurality of image snippets based on corner features of the image of the real-world scene;

    associating metadata having selected features with the image of the real-world scene;

    storing the image and the metadata, the metadata being stored in a metadata file;

    analyzing at least one frame of the image for corner feature information;

    manipulating a retrieved image corresponding to an displayed image snippet based on matching corner feature information of the displayed image snippet generated and provided by the server and corner features of the image of the real-world scene, wherein the retrieved image is retrieved with metadata having selected features; and

    combining the manipulated image with a currently observed real-world scene viewed with the portable electronic device.
