Abstract:
1. An apparatus for Internet browsing and other Internet-interactive activities, which apparatus comprises: a camera to focus on to a printed hypertext document for generating video signals representing an image of the printed hypertext document in electronic form; a processor linked to the camera for processing an image captured by the camera of the printed hypertext document and of a pointer within the field of view of the camera pointing to a region of the printed hypertext document and configured to determine from the image the identity of a linked web page or a linked multi-media data file referred to on the hypertext document in the region pointed to, and to then fetch from the Internet or a local cache of web pages data that comprises the linked web page or linked multimedia data file referenced in the printed hypertext document; and a receiver for receiving and displaying or playing the fetched data, wherein the image captured by the camera includes the printed hypertext document and the pointer, the pointer not being a part of the printed hypertext document, wherein the pointer points to the region of the printed hypertext document without writing on the printed hypertext document, wherein the processor is to determine the identity of the linked web page or the linked multi-media data file referred to on the hypertext document in the region pointed to by determining where the pointer points to within the image captured by the camera, wherein the pointer is one of a finger of a user and a pointing implement other than a finger of the user, wherein where the pointer is a finger of the user, the processor is to detect the finger of the user within the image captured by the camera responsive to the user performing a predetermined movement of the finger, and wherein where the pointer is a pointing implement, the processor is to detect the pointer by detecting a readily differentiated, locatable, and identifiable marker at a tip of the pointing implement within the image captured by the camera, wherein the processor is to detect a first calibration mark printed on the printed hypertext document, a second calibration mark printed on the printed hypertext document, and a third calibration mark printed on the printed hypertext document to determine a location, orientation, and scale of the printed hypertext document, where the first calibration mark, the second calibration mark, and the third calibration mark are identical to one another and form an L-shape with respect to an aspect ratio of the printed hypertext document.
