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. Additionally, proximity sensors are associated with one or more portions of the document. Thus, the range of dynamic content can also be activated by placing an object within the sensible area of the proximity sensors. This dynamic content can include, for example, lighting, sound effects, environmental conditions, or the like.
