Abstract
Identifier tags are embedded in pages of a document. Each of these identifier tags identifies the particular page that a reader is viewing. By correlating the currently read page to information stored memory, dynamic content corresponding to the currently read page can be activated. This dynamic content can include, for example, lighting, sound effects, environmental conditions, or the like.
