  • Patent number: 7667703
    Abstract: A system and method for turning pages of a three-dimensional electronic book. A closed three-dimensional electronic book is modeled as at least one three-dimensional object having length, width and thickness dimensions. An opened three-dimensional book electronic is modeled as at least two three-dimensional objects having length, width and thickness dimensions, representing the left side of the opened book and the right side of the opened book. The page(s) to be turned is modeled as at least a three-dimensional object having length, width and thickness dimensions. The cross-section parallelogram having a width dimension and a thickness dimension based on the width and thickness dimensions of the closed three-dimensional electronic book, and a user-selected number of page(s) to be turned.

  • Publication number: 20100011281
    Abstract: To annotate a three-dimensional electronic document, a user specifies, on a two-dimensional screen, a portion of a page of a three-dimensional document as a specified page area to be annotated by making a stroke. The annotation may be displayed to the user by a hybrid technique where the annotation is displayed by a 3D polyline segment placed behind the near clipping plane of a virtual camera frustum. At the same time, previous annotations are displayed by another technique, such as, for example, the texture coloring technique. During the intermittent time between the stroke and another stroke the 3D polyline segment is removed from behind the near clipping plane and the page texture is updated with the annotation data. The display techniques support highlighting annotations, free-form annotations, and text annotations.

  • Publication number: 20080040378
    Abstract: Techniques provide for the dynamic display of a page-oriented information asset using an audio output mode. Pluralities of elements in the page-oriented information asset are determined based on chapters, sections, paragraphs, sentences, words and the like. The elements are rendered to an audio output mode. Optionally selectable representations of the elements are also determined and output using a 3-dimension-like rendering to a visual output mode. The 3-dimension-like rendering of the visual representations of the elements shows how the current element relates to the other elements and its location within the page-oriented information asset. The 3-dimension-like rendering provides visual orientation or context within the page-oriented information asset. The visual representations of the elements are optionally selectable as spatial context indicators providing direct navigation control to support reading, browsing and information retrieval tasks within the page-oriented information asset.

  • Publication number: 20080027707
    Abstract: Techniques are described that provide a reading pane for reading one or more content portions of a work and a guide pane that displays a structured overview of additional information from the corpus that is focused by an analysis of information from the currently-visible content portion of the work. The contents of the currently-visible content portion displayed within the reading page are used to derive dynamic representations of the user's immediate interests. At the user's request, a structured persistent context-aware guide is computed and displayed. The persistent context-aware guide provides a framework for accessing other parts of the corpus having the most-related information. The elements in the persistent context-aware guide are other content portions or other organizations such as sections, chapters, or articles in the corpus. The persistent context-aware guide may also incorporate additional closely-related information elements from outside the corpus including advertisements.

  • Patent number: 7239316
    Abstract: An interactive display system includes a display such as a cathode ray tube (CRT), for example, and a display controller. The display controller and display operate in concert to display graphical images that are representative of numerical, tabular, data. The display system may be used to edit, for example, to create or modify, the data tables being graphically represented. The edited data tables may be used to simulate processes, such as workflow processes.

  • Patent number: 7164789
    Abstract: A method for reconstructing three dimensional shapes from two dimensional image domains uses glyph address carpets as a structured light pattern. The glyph address carpet includes a glyph encoding scheme in which the coordinates of any given point can be computed by looking at the glyph marks in a small neighborhood. The method includes calibrating at least one projecting device and at least one image detecting device and projecting a glyph address carpet pattern onto a three dimensional figure. The projected glyph address carpet pattern is detected and used to reconstruct the three dimensional coordinates for each readable glyph mark within the projected glyph address carpet pattern.

  • Patent number: 7148905
    Abstract: A system and method for annotating three-dimensional electronic documents. A user specifies, on a two-dimensional screen, a portion of a page of a three-dimensional document as a specific page area to be annotated. The annotation is displayed to the user with the transparent polygon technique, the vertex coloring technique and/or the texture coloring technique. These display techniques support highlighting annotations, free-form annotations, and text annotations.

  • Publication number: 20060156222
    Abstract: A method is disclosed for automatically performing conceptual highlighting of electronic text. User's interests can be explicitly determined via keywords that the user specifies, and/or are implicitly constructed from user browsing and reading activity. User interests may be expressed as an interest profile. Conceptual keywords related to user interests are selected by combining spreading activation and word co-occurrence, by latent semantic analysis, or other methods. The invention automatically highlights sentences and other information that contain conceptual keywords related to user interests. Highlights can be activated when the user directly performs a keyword search or index search, or the invention can generate information reflecting user interests, apply it to the text, and generate and display highlights. An algorithm is disclosed for computing a conceptual keyword vector through an iterative spreading activation process also employing word co-occurrence.

  • Patent number: 6972761
    Abstract: A work center monitoring system includes an output device, such as a cathode ray tube (CRT), liquid crystal display (LCD), or other display device and a display controller. The controller formats work center information to be displayed on the output device as single-valued and multi-valued display segments. Each segment displays information related to work center activities, which may be categorized as various skills. The displays may be provided to a work center supervisor to assist in the management of a work center, such as a contact and fulfillment center. Current and historical values of the parameters may be displayed, simultaneously, or in sequence. The values of the displayed parameters may be different types, such as any of a variety of numerical representations which might represent the number of calls in one or more queues, or the oldest call in a queue, for example. The values may be indicative of the elapsed time for servicing the oldest call in a queue, or other indications of time.

  • Patent number: 6720967
    Abstract: A workflow display system in accordance with the principles of the present invention includes an output device, such as a cathode ray tube (CRT), liquid crystal display (LCD), or other display device and a display controller. The display controller and display operate in concert to display graphical images that are representative of workflow information. Textual information may also be displayed. Such a display may employ the size, color, and number of glyphs to represent the number of work units in one or more work states. Other display characteristics, such as patterns, flashing, or other such visual queues may also be employed to convey information about workflow in a manner which is readily comprehensible. For example, in a telephone contact and fulfillment center application, the size and/or number of circles may indicate the number of waiting calls in a given state.
