ABSTRACT:
An automated method and apparatus for assisting a reader to read a printed or scribed document that cites, directly or indirectly, other information. A camera focuses down on the document for generating video signals representing an image of the document in electronic form, and a processor linked to the camera processes the image of the document captured by the camera, the processor being configured to fetch information from a database when a user, by pointing to a position on the document, selects a position within the image. The document is placed within the field of view of the camera and finger or pointing implement is placed within the field of view of the camera to a selected position on the document. The camera captures an image of the document and of the finger or pointing implement overlying the document. The processor processes the captured image to recognize the position on the document selected by the finger or pointing implement and information is fetched that is cited, directly or indirectly, at that position in the page of the document.
