Abstract

The present invention discloses a method for producing graphical indicators and interactive systems for utilizing the graphical indicators. On the surface of an object, visually negligible graphical indicators are provided. The graphical indicators and main information, i.e. text or pictures, co-exist on the surface of object. The graphical indicators do not interfere with the main information when the perception of human eyes are concerned. With the graphical indicators, further information other than the main information on the surface of object are carried. In addition to the main information on the surface of object, one is able to obtain additional information through an auxiliary electronic device or trigger an interactive operation.

Claims

1. An electronic book system comprising:

an optical device for capturing an image from a selected zone on a surface of a page of a book by a user, wherein the image includes a graphical indicator that has a visually negligible size and is affixed on the surface of the page of the book;

a processing circuitry coupled to the optical device for receiving the image, the processing circuitry retrieving the graphical indicator from the image and acquiring an additional information corresponding to the graphical indicator by processing and/or transforming the graphical indicators;

a speech circuitry retrieving the additional information and acquiring an audio information corresponding to the additional information by processing and/or transforming the additional information; and

a speaker coupled to the speech circuitry for outputting a sound corresponding to the audio information.

2. The electronic book system of claim 1, wherein the graphical indicator comprises a plurality of graphical micro-units arranged in a layout, the layout corresponds to an indicator information, the processing circuitry analyses the layout of the graphical micro-units to retrieve the indicator information and further to acquire the additional information from the indicator information by processing and/or transforming the graphical indicators.

3. The electronic book system of claim 2, wherein each graphical indicator occupies very small amount of area, and each graphical micro-unit occupies very small amount of area, and number of graphic micro-units of each graphical indicator is substantially equal to each other.

4. The electronic book system of claim 2, wherein the surface of the page of the book comprises a main information that overlaps and co-exists with the graphical micro-units on the surface of the page of the book, wherein the graphical micro-units are negligible when the user observes the main information.

5. The electronic book system of claim 4, wherein the graphical indicator comprises a plurality of state zones for selectively respectively storing the graphical micro-units, wherein each of the state zones displays a state from at least two candidate states.

6. The electronic book system of claim 5, wherein the candidate states comprise a first state and a second state, as in the first state, the state zone includes one graphical micro-unit, and as in the second state, the state zone does not include the graphical micro-unit.
