Methods for recognizing gestures made by a conductive object on a touch-sensor pad are disclosed. Tapping, pushing, hopping, and zigzag gestures are recognized by analyzing the position, pressure, and movement of the conductive object on the sensor pad during the time of a suspected gesture, and signals are sent to a host indicating the occurrence of these gestures. Signals for compensating for unintended motion of the conductive object on the touch-sensor pad during the gestures are also sent to the host.

A deterministic finite automaton uses binary search (and optionally hashing) method(s) of sparse matrix representation to recognize the graphical representations of characters or icons from a bitmap representation of the computer screen. This recognition can be applied to translate data from an unknown form of original specification (file format) into a known form of representation, such as HTML. Alternatively this recognition can be applied to another process that can “see” what is on the screen, and perform programmed actions, based on what it “sees”.

A pen-based computer text input system capable of interpreting a special pre-defined set of single stroke glyphs. Each input stroke is identified with one of three categories: (1) pre-character modifier strokes, (2) character or symbol strokes, or (3) post-character modifier strokes. Pre-character modifier strokes precede character strokes and inform the present recognition system that a subsequently entered character stroke is to be modified by the pre-character modifier stroke in a pre-defined manner. Character strokes cause a character or symbol to be displayed on the display device the moment it is input on the writing tablet, interpreted in accordance with any pre-character modifier stroke. A post-character modifier stroke causes the recognition system to modify, in a pre-defined manner, a character or symbol which was previously entered and displayed. An important advantage of the present invention is its ability to provide immediate recognition of multiple stroke characters without using boxed input.

Pronunciation for an input word is modeled by generating a set of candidate phoneme strings having pronunciations close to the input word in an orthographic space. Phoneme sub-strings in the set are selected as the pronunciation. In one aspect, a first closeness measure between phoneme strings for words chosen from a dictionary and contexts within the input word is used to determine the candidate phoneme strings. The words are chosen from the dictionary based on a second closeness measure between a representation of the input word in the orthographic space and orthographic anchors corresponding to the words in the dictionary. In another aspect, the phoneme sub-strings are selected by aligning the candidate phoneme strings on common phoneme sub-strings to produce an occurrence count, which is used to choose the phoneme sub-strings for the pronunciation.

A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

Some embodiments provide a method for analyzing an unstructured document that includes a number of glyphs, each of which has a position in the unstructured document. Based on positions of the glyphs in the unstructured document, the method creates associations between different sets of glyphs in order to identify different sets of glyphs as different words. The method creates associations between different sets of words in order to identify different sets of words as different paragraphs. The method defines associations between paragraphs that are not contiguous in order to define a reading order for the paragraphs.

The present invention concerns a method allowing an author to create a bitmap font and distributing it to at least an user's device connected to a server (2), comprising the steps of:

• • drawing on an author's device and/or importing (5) in the author's device an image comprising at least one glyph;
  • segmentation (6) of the image by the said author's device, in order to isolate the glyph or the different glyphs;
  • uploading the bitmap file resulting of this segmentation (6) to the server (2);
  • displaying (34) a text on said user's device, said text being rendered with a font depending on said bitmap file.

The present invention relates also to a system and a computer program product for creating and sharing personalized font on a client-server architecture.

An apparatus and method for converting information from a text format to an audio format using distributed processing. A first set of computer readable program instructions receive information from a data source, convert the information from the text format to an intermediate format, and transmit the information in the intermediate format to a second data processor. A second set of program instructions, executable on the second data processor, are also included to convert the information from the intermediate format to the audio format. The first set of program instructions are executed on a remote, or server side, data processor, while the second set of program instructions are executed on a client side data processor. The first set of program instructions expand the information in the text format into phonemes using a grapheme to phoneme dictionary. The second set of program instructions convert the phonemes to audio output signals.

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 “Character-Level Font Linker” provides character-level linking of fonts via Unicode code-point to font mapping. A lookup table is used to identify glyph-level support for runs of particular characters on a Unicode code-point basis for relative to a set of available fonts. This lookup table enables automatic selection of one or more specific fonts for rendering one or more runs of characters comprising a text string. The lookup table is constructed offline by automatically evaluating glyphs comprising a set of common or default fonts. The table is then used for automatically selecting fonts for rendering text strings. Alternately, the lookup table is generated (or updated) locally to include some or all locally installed fonts. Finally, in another embodiment, if no supporting font is identified in the table for a particular character, the system automatically downloads the necessary glyph from one or more remote servers.

Methods and system for dynamic font subsetting. One or more directives are inserted into electronic content to identify one or more glyph sub-sets needed to display the multiple characters in one or more desired languages for electronic content. A directive identifies a glyph sub-set including set of glyphs identified in the electronic content and an encoding scheme used to encode the set of glyphs. The glyph sub-set identifies only those glyphs needed to display the electronic content. When electronic content with the one or more directives is processed the one or more directives are identified. If the electronic device does not have the glyph sub-sets needed to display the electronic content, requests are sent to an intermediate network device to obtain glyph sub-sets. These method and system may allow an electronic device with limited resources, such as a wireless telephone, personal digital assistant, network appliance, set-top box, etc., to display electronic content from a computer network such as the Internet or an intranet, with virtually any font, even if the fonts from the electronic content do not exist on the electronic device. Electronic content written in languages such as Chinese, Japanese, Korean, Vietnamese, etc. can be displayed on an electronic device with limited resources using a small number of glyphs from the multiple thousands of possible glyphs that represent characters in such languages.

A method of decoding a plurality of glyphs comprising the steps of scanning a group of glyphs to form image data for expected glyph locations, assigning for each location a first value indicative of the likelihood that location contains a glyph in a first state, assigning for each location a second value indicative of the likelihood that location contains a glyph in a second state, determining the difference between the first and second values for each potential glyph location, establishing a distribution analysis of the determined differences and using that distribution analysis at least in part to control decoding of the plurality of glyphs.

A method and system are disclosed for field level encryption of a document that provides a hardcopy having redacted sensitive information fields with multiple levels of access and an augmented reality view of the hardcopy displaying the unredacted sensitive information fields. Identification of the sensitive information fields may be accomplished via highlight color, user designation, or linguistic analysis. The identified fields are encrypted and may be stored separately, embedded in place, or embedded in a two-dimensional glyph. This information may be stored in association with a device identification of an authenticated mobile device and a document identification. A redacted hardcopy of the original document is output. A mobile device captures an image of the redacted hardcopy, decrypts the encrypted sensitive information fields, and generates an augmented reality view of the hardcopy with the previously redacted sensitive information fields visible on the display of the mobile device.

Systems and techniques for translating user interaction with a touch screen into input commands. In one aspect, a touch screen system includes a touch screen graphical display, a command interpreter configured to identify modifier interactions with the graphical display and, in response to identification of the modifier interaction, modify the interpretation of other interaction with the graphical display, one or more persistent data storage devices. The data storage devices store a first set of rules for interpreting user interaction with the graphical display and a second set of rules for interpreting user interaction with the graphical display. The first set of rules interpret motion across a map or a proper subset of a collection of information as a scrolling or panning command. The second set of rules interpret the motion as a glyph. The command interpreter is configured to modify the interpretation of the other interaction by switching between interpretation under the first set of rules and interpretation under the second set of rules.

A 2D image supplied from an image input unit including a wide view lens is sampled into a discrete form by an array sensor, and then mapped to a multi-resolution space by a 2D filter. The feature of the supplied image is detected, and then the mapped image is transformed to a local pattern about the detected feature, and then the coordinates of the position of the feature and the code word of the local pattern are formed into a set which is then encoded. The code is supplied to each cell of a stochastic automaton. The quantity of visual information is calculated in accordance with the quantity of mutual information between different cells of the stochastic automaton consisting of cells in blocks, the coordinates of the position of the feature and the distance from the feature to the optical axis so as to control the optical axis of the image input unit in such a manner that the quantity of visual information is maximized.

Described is a system and method by which text elements to be rendered on a computer display (e.g., paragraph, line or any subset of text including a character or glyph) may be individually or collectively animated, at an author-selected level of granularity. Animation of text may be specified by setting animation properties via direct coding (e.g., in markup) or by specifying animation code to execute on text-related data, just prior to rendering. The text to animate may be static, or dynamically obtained at runtime from an external source. The text to animate is maintained as a whole with other text of the same element, in a text object, until a processing level that produces separate glyph runs, with an animation transform associated with each glyph run to be animated. Also described is an API that supports text animation.

A design system for designing complex integrated circuits (ICs), a method of IC design and program product therefor. A layout unit receives a circuit description representing portions in a grid and glyph format. A checking unit checks grid and glyph portions of the design. An elaboration unit generates a target layout from the checked design. A data prep unit prepares the target layout for mask making. A pattern caching unit selectively replaces portions of the design with previously cached results for improved design efficiency.
