A method of providing information to a user via a printed substrate, said substrate comprising user information and coded data, said coded data being indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said method comprising the steps of: receiving, in a computer system, interaction data indicative of the region identity and at least one position of a sensing device relative to the substrate, the sensing device generating the interaction data, when operatively positioned or moved relative to the substrate, by reading at least some of the coded data; identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity; determining, using the page description and the position of the sensing device, whether the sensing device is positioned within a zone of a hyperlink on the substrate; and (i) if the sensing device is positioned within a zone of a hyperlink: sending a hyperlink URI or a hyperlinked resource corresponding to the hyperlink to the user; or (ii) if the sensing device is positioned outside a zone of a hyperlink: generating a query expression comprising one or more search terms, at least one of said search terms being identified using the page description and the at least one position of the sensing device; forming a request using the query expression; and sending the request, or a results resource including search results obtained using the request, to the user.
