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.
