Abstract

An electronic book apparatus that comprises multiple pages (122) with printed information (126), a visual signal (125) for identifying the printed information in a sequentially organized manner, a synchronized audio signal (154) for describing and further identifying the information concurrently with the visual signal, and a switch (127) for electronically controlling the generation and transmission of these signals when each particular page is opened for viewing. Each page of the electronic book includes a laminated sheet (124), on which the printed material is arranged, and an electronic backdrop (121) containing the visual signal for display through the laminated sheet. Separate intelligent electronics (160) in the spine (140) and top portion (150) of the book, coupled to the a switch, activate the illuminating circuitry and a voice synthesizer (168) that are synchronized and sequenced to produce a concurrent visual and audio enhancement of the printed matter being viewed on the page.
