Abstract

A system for displaying audio content with text including a book holder and a book. The book holder identifies which book of a plurality is placed in the holder by detecting magnetic indicators in specific locations and arrangements which are unique to each book. The page of the book which a user views at any given time is identified by detection of ambient light, by detection of a number of circuit elements in parallel, by detection of progressively stacked magnetic sensors, or by microwave reflection.

Claims (11)

1. A system for displaying audio with text, comprising: a book holder designed to receive a book, the book having a plurality of pages; a first conductive material placed on each page of the plurality of pages; a first resistive material placed on each page of the plurality of pages; wherein the first conductive material and the first resistive material on each page of the plurality combines to form a first circuit when the pages of the plurality are overlaid such that the resistive material of each page is electrically connected in parallel with the resistive material of the other pages of the plurality; the book further comprising at least one additional element that may be read by the book holder, wherein the location of said magnetic signature is utilized to identify a particular book.

2. The system of claim 1 , wherein the first circuit includes a node, and wherein the measured voltage at the node indicates which page of the plurality is currently being viewed by a user.

3. The system of claim 1 , wherein the first circuit includes components located in the book holder.

4. The system of claim 1 , wherein said at least one additional element is a plurality of magnetic signatures.

5. The system of claim 4 , wherein said plurality of magnetic signatures is used to identify a particular book.

6. The system of claim 1 , wherein the first conductive material is conductive ink.

7. The system of claim 1 , wherein the first conductive material is conductive tape.

8. The system of claim 1 , wherein said at least one additional element is read by the book holder to identify a particular book.

9. The system of claim 1 , wherein said at least one additional element is a second circuit.

10. The system of claim 9 , wherein said second circuit includes a second resistive material and a second conductive material.

11. The system of claim 1 , wherein said plurality of pages includes a back page and wherein said at least one additional element is associated with said back page.
