摘要： Systems and methods that determine a path of a pen tip as the pen tip is moved across a document are described. The document is watermarked with a maze pattern from which encoded position information is determined. A sequence of images is captured by a camera that is located in a pen. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. If the position coordinates of any frame that is associated with a stroke cannot be determined from m-array decoding, the frames are transformed and then matched with an area of a document image. Once the position coordinates of at least one frame is determined, the position coordinates of other frames are determined by matching the frames in a neighboring area.

摘要： A method and system for presenting data on a medium for capture by an input device is described. The method embeds a symbol design, such as an embedded interaction code (EIC), in an image on a display screen, such as a liquid crystal display (LCD). A grid with a plurality of pixels defines a size of an EIC pattern on an LCD. An area of the grid is used to embed position data and/or metadata information. The area may be defined by a sub-pixel of the plurality of pixels and/or the edges of the grid itself. The sub-pixel with the EIC pattern may be configured to have a grey value based upon a color of an underlying image associated with an application program being displayed on the LCD. The method also allows for decoding of the position data and/or metadata information in the EIC pattern on the LCD.

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： A system and method is described for providing an encoding scheme for a bit stream and displaying or printing the encoded bit stream. Using the encoded bit stream, a pen with a camera may capture an image of a portion of the encoded bit stream. The captured image may then be decoded to provide an indication of the location of the image in relation to the encoded bit stream. The encoding scheme includes information regarding orientation, thus making decoding easier.

摘要： An efficient technique is provided for determining a portion of a document corresponding to a captured image. Areas of a document in which the pattern is at least partially obscured are identified. A reference pixel in the image is selected, and an offset between the pixel and the pattern is determined. A pixel-by-pixel comparison is then made of the image with the document such that the reference pixel is only compared with locations in the document that are both within the identified areas and have the determined offset from the pattern. The comparison with the highest correspondence between the image pixels and the electronic document then identifies the position of the reference pixel relative to the electronic document.

摘要： An embedded interaction code-enabled display includes: an outer transparency layer, an optional inner transparency layer, an optional infrared-reflection layer between the outer transparency layer and the inner transparency layer, an EIC dot pattern between the outer transparency layer and the infrared-reflection layer, and, optionally, transparency glue between the outer transparency layer and the infrared-reflection layer or the inner transparency layer. The outer transparency layer 1308 and the inner transparency layer may be glass, plastic, or a film. The EIC dot pattern may be printed on, or pressed onto, the inner side of the outer transparency layer. The EIC dot pattern may include an encoded surface identifier that identifies the embedded interaction code-enabled display. The encoded surface identifier may uniquely identify the embedded interaction code-enabled display.

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： A technique is disclosed for determining a portion of a document corresponding to a captured image. A user employs a pen to create a stroke in a document, and images are captured by a camera mounted on the pen. The locations of some of the images are determined by, e.g., analyzing a pattern on the document captured by the image or by a pixel-by-pixel comparison of the image with the document. The locations of other images are determined by segmenting the sequence of images into groups corresponding to the shape of the stroke. Information relating to a located image in a segment is employed to determine the position of an unlocated image in the segment. This determined position is used for obtaining further information that may be used to determine the position of another unlocated image in the segment, and so on, until the segment is finished.
