Digital ink annotations of digital documents are captured, processed, and stored for later retrieval. Elements within the digital documents are found and data concerning them are stored, in order that they may be associated with the digital ink annotation and serve as anchors for the digital ink annotations within the digital documents being annotated. Furthermore, a markup language schema is used for the efficient, standardized storage of the digital ink annotations. By these means, digital ink annotations are stored efficiently, retrieved, and rendered accurately across different types of browsers and operating systems, as well as across different size browser windows and output devices.

Recorded video is accessed from printed notes or summaries derived from the video. Summaries may be created automatically by analyzing the recorded video, and annotations are made by a user on a device for note-taking with digital ink and video. The notes and/or summaries are printed along with data glyphs that provide time based indexes or offsets into the recorded video. The indexes or offsets are retrieved by scanning the glyph on the printout. The glyph information can be embedded in the printouts in many ways. One method is to associate block glyphs with annotations or images on the printed pages. Another method is to provide an address carpet in an annotated timeline. Yet another method is to provide a two-dimensional address carpet with X-Y position mapped to time which can be used to provide selected access to the video. The accessed video may be played back on the note-taking device on a pen computer, or on a summary interface on a Web browser-type device.

A method and system that converts ballistic movement of a pen (e.g., movement of a pen point across a surface) into thickness information for digital ink data. The pen includes at least one accelerometer that is used to generate the ballistic information. A thickness conversion component may be located on a computer that is remote from the pen, and the ballistic information is transmitted to the computer via a hardwired or wireless connection. The accelerometer generates the ballistic information in the form of pulses, the width of which is directly related to the acceleration of the pen movements. The thickness conversion component converts the acceleration information, with or without additional information such as coordinate information, into thickness information for digital ink. This thickness information may be used to generate variably thick lines, which may be useful for a variety of applications, for example, better display and improved recognition.

The ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dye, 2 to 15 percent of dispersing agent, 10 to 60 percent of deionized water, 10 to 50 percent of water soluble organic solvent, 0.1 to 5 percent of surface active agent, 0.05 to 0.5 percent of germicide, and 0.05 to 0.5 percent of defoaming agent. The preparation method comprises the following steps of: mixing 1 to 20 percent of dispersing agent, 10 to 40 percent of water soluble organic solvent, 0.1 to 2 percent of germicide, 0.1 to 2 percent of defoaming agent, and 30 to 50 percent of deionized water, adding 1 to 20 percent of disperse dye while stirring, and grinding the mixed solution to obtain color paste; uniformly mixing 15 to 50 percent of color paste, 10 to 30 percent of water soluble organic solvent, 0.1 to 5 percent of surface active agent and 20 to 50 percent of deionized water and filtering the mixed solution to obtain the waterborne digital ink-jet printing sublimation ink. When the waterborne digital ink-jet printing sublimation ink is used in a large-sized ink-jet printer using waterborne ink, the good printing smoothness and the water retention of a printing head are achieved, and the preparation process is simple.

A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.; producing a test print by applying a decorative pattern to the baseweb by a digital ink jet printer and making an optional software-driven image-related adjustment in the standard to color match the standard to the test print image; and when the adjusted standard image displayed on the screen is acceptable, passing an image-related output to the digital ink jet printer for printing a decorative print color-matched to the accepted onscreen standard.

The invention relates to a fabric pre-treating method for digital ink-jet printing of a dispersed dye, which comprises the following steps of: (1) uniformly mixing 1 to 5 percent of water-soluble organic polymer, 2 to 3 percent of porous inorganic nano particle, 0.1 to 2 percent of surfactant and water to form a pre-treating agent; and (2) dipping, padding and coating a fabric dyed by a dispersed dye or sparing the pre-treating agent on the fabric dyed by the dispersed dye, wherein the fabric carrying liquid rate is 50 to 90 percent, drying the fabric, and heating the fabric at 180 to 220 DEG C for 0.5 to 20 minutes. The method of the invention is simple, low in cost and suitable for industrial production; the direct ink-jet printing of the fabric with the pre-treating agent has the advantages of uniform color, inhibited penetration phenomenon, high printing precision, sharp boundaries of patterns, clear detail and bright color; and the fabric offers a soft hand feel and has very good washing, friction and color fastness to light.

A method and process provides structure recognition to a node-link diagram formed by a plurality of digital ink strokes drawn on a canvas of an electronic device by an input device. The method and process include grouping related strokes into multiple hypotheses reflecting structure interpretations of the strokes in a group. Confidence scores are computed for the multiple hypotheses based on local evidence regarding the strokes of the stroke groups and surrounding strokes. Constraints are applied among the hypotheses, and a collectively high scoring assignment of accept/reject values of the hypotheses are determined under the applied constraints. The hypotheses with collectively high scoring assignments are accepted as a representation of the node-link diagram, where structure information is provided to the strokes of the node-link diagram, making the node-link diagram electronically editable.

A method (400) and apparatus (1000) for compressing digital ink such as a hand-drawn object (104) are provided. The hand-drawn object is first prepared (406, 1010) and then Bezier curves based upon the hand-drawn object are generated (408, 1012). The Bezier curve representation (202) of the hand-drawn object (104) is further compressed (418, 1018) by modifying Bezier control points to produce a compressed Bezier curve representation (302) of the hand-drawn object (104).

A system and method for ink database searching using handwriting feature synthesis is disclosed which allows a digital ink database to be searched using a text-based query. Using a writer-specific handwriting model derived from a handwriting recognition system or suitable training procedure, a text query is converted into feature vectors that are similar to the feature vectors that would have been extracted had the author of the digital ink database written the text query by hand. The feature vectors are then used to search the database. This allows the searching of a digital ink database when the only input mechanism available is text entry, and can allow a person other than the author of the digital ink database to search the digital ink database.
