Abstract: Clustering-definition-based encoding schemes printed as a computer-oriented digital layer onto a physical surface whereby the surface functions as an interface enabling, via a simple image-acquisition device scanning a minimal field required to establish the clustering definition, the provision, to a suitable data processing and human-oriented display means, of feedback on the orientation of the image-acquisition device relative to the digital layer overall.

Abstract: [Problem to be Solved] To provide a digital information carrier which enables blending of cluster information carrier comprising of image objects joined together to other viewable content (a character, an image, background, etc.) of a document, to seamlessly unify a printed document and an electronic document when accessing the cluster information carrier by an image recognition means, such as partial scanning, and to perform a method for finding positional information and processing commutative with the written contents of the document without incorrect recognition at high speed and a method for recognition. [Solution Means] A digital information carrier comprising of a plurality of image objects as constituent elements, containing a cluster information carrier constituted by at least two image objects, and having bit data correlated to the relative relationship of at least two image objects concerned serving as configuration elements were used.
