摘要： In accordance with embodiments of the invention, local metadata is embedded into an embedded interactive code document by combining a first m-array and a second m-array to generate a combined m-array with encoded local metadata such that a start position of the second m-array in the combined m-array is shifted, by an amount that is based on the local metadata, relative to a start position of the first m-array in the combined m-array. The first m-array and the second m-array may contain the same repeating bit sequence. Local metadata may be decoded from the embedded interactive code document by decoding the local metadata from the combined m-array by determining the amount by which the second m-array is shifted, relative to the first m-array, in the combined m-array.

摘要： Embodiments of the invention configure and analyze an embedded interaction code (EIC) array of an EIC document. An EIC font, having a selected geometric shape, is configured so that a generated EIC symbol encodes EIC data. The EIC font is configured with at least one orientation dot so that a captured image can be properly orientated. An EIC document system is configured to support a desired address space of an EIC array, a desired decoding performance, and a desired level of readability of an EIC document. An EIC font is configured to include a plurality of data dots along an edge. The selection of the EIC font takes into consideration a number of dimensions and the order of a constituent m-array, which is associated with one of the dimensions. An EIC font may be configured with at least one clock dot to support segmenting EIC symbols in the captured image.

摘要： In accordance with embodiments of the invention, global metadata, such as a document identifier, which may be a globally unique identifier, is embedded into an embedded interactive code document by combining a first m-array and a plurality of copies of the first m-array to generate a combined m-array with encoded global metadata such that respective start positions (xd,yd)i of the plurality of copies of the first m-array in the combined m-array are each shifted, by respective amounts that are based on respective portions of the global metadata, relative to a start position of the first m-array in the combined m-array. Global metadata may be decoded from the combined m-array by determining the respective amounts by which the plurality of copies of the first m-array are shifted, relative to the first m-array, in the combined m-array and by combining the respective amounts to produce a decoded value of the global metadata.
