Abstract

Interactive electronic system having a screen and a three-axis compass sensor for detecting flipping of pages of a book, wherein the book comprises a plurality of pages, each having with one or more magnets, and wherein the system is arranged to detect the flipping of pages of the book by the data readings of the value of one axis, X, Y, or Z; or the magnitude of the calculated vector of the values of the axes X, Y, and Z. Also a method of interaction comprises: downloading the software of the book to the electronic device; putting the book which contains the sensors in a pre-determined area near the electronic device in manner to identify the pages; calibrating the system; obtaining the values of the magnitude of the magnetic field by the compass sensor to detect the page that is open; displaying the corresponding digital content in synchronization.

First claim

The invention claimed is:

1. An interactive electronic system having a screen and a three-axis, X, Y, or Z, compass sensor for detecting flipping of pages of a book,
wherein the book comprises a plurality of pages, each page having one or more magnets,
wherein the interactive electronic system is calibrated by reading a baseline value of a magnitude of a magnetic field by the three-axis compass sensor and including previously recorded values of the three-axis compass sensor readings for each page of the plurality of pages, for different distances, in software corresponding to the book to serve as reference values,
and wherein the interactive electronic system is arranged to detect the flipping of pages of the book by data readings of the value of one axis of the three axes, X, Y, or Z, or the magnitude of a calculated vector of the values of the three axes X, Y, and Z.

2. The interactive electronic system according to claim 1 , wherein a location of a magnet on a book page is such as to, when flipping a book page, the magnet moves from a distance closest to the three-axis compass sensor to a distance furthest away from the three-axis compass sensor, in order to provoke a maximum change of magnetic field.

3. The interactive electronic system according to claim 1 , wherein the one or more magnets are included within a thickness of each page.

4. The interactive electronic system according to claim 1 , wherein the number of magnets corresponds to the number of pages that are to be identified by the interactive electronic system.

5. The interactive electronic system according to claim 1 , wherein a thickness of the one or more magnets is the same as a thickness of each page.

6. The interactive electronic system according to claim 5 , wherein the thickness of the one or more magnets is 1 mm.

7. The interactive electronic system according to claim 1 , arranged such that when the three-axis compass sensor senses a change on the magnetic field of flipping a book page, information that is presented on the screen is also changed.

8. The interactive electronic system according to claim 1 , wherein the interactive electronic system only uses one magnet.

9. The interactive electronic system according to claim 8 , wherein the magnet is located on a back cover of the book, a front cover of the book, or any single page of the book.

10. The interactive electronic system according to claim 1 , wherein the electronic system is a tablet or a device having a screen.

11. A method of operating an interactive electronic system having a screen and a three-axis compass sensor for detecting flipping of pages of a book, wherein the book comprises a plurality of pages, each page having one or more magnets, and wherein the interactive electronic system is arranged to detect a flipping of pages of the book by data readings of a value of one axis, X, Y, or Z, or a magnitude of a calculated vector of the values of the three axes X, Y, and Z, wherein said method comprises the steps of:
a) downloading a software corresponding to the book to an electronic device;
b) putting the book, which contains the one or more magnets, in a pre-determined area near the electronic device to identify the flipping of pages;
c) calibrating the system by reading a baseline value of a magnitude of a magnetic field by the compass three-axis sensor and including previously recorded values of the three-axis compass sensor readings for each page, for different distances, in the software to serve as reference values;
d) obtaining the values of the magnitude of the magnetic field by the three-axis compass sensor of the electronic device to detect which page of the book is open; and
e) displaying corresponding digital content in synchronization with the open page.

12. The method according to claim 11 , wherein a position of the book is left, right, above or on top of the electronic device.

13. The method according to claim 11 , wherein the electronic device is in landscape relative to a user and the book is above or below the electronic device.

14. The method according to claim 11 , wherein the magnitude of the magnetic field obtained by the reading of the three-axis compass sensor is obtained through data readings per each axis (X, Y, Z) with the magnitude of that vector being calculated, or only the value of one axis of the three-axis compass sensor is used.

15. The method according to claim 11 , further comprising moving the magnet when a user flips the book page from a distance closest to the three-axis sensor to a distance furthest away from the three-axis compass sensor to provoke the maximum change on the magnetic field to change the information displayed on the electronic device.

16. The method according to claim 11 , wherein a user interacts with a book story through the electronic device.

17. Non-transitory storage media including program instructions for implementing an interactive electronic system having a screen and a three-axis compass sensor for detecting flipping of pages of a book, the program instructions including instructions executable to carry out the method of claim 11 .

18. Non-transitory storage media including program instructions for implementing an interactive electronic system having a screen and a three-axis compass sensor for detecting flipping of pages of a book, the program instructions including instructions executable to carry out the method of claim 14 .
