Abstract: A system and method of social interaction includes receiving interaction information for an interaction created by a first user of an electronic content work, the interaction information comprising an identification number of a portion of the electronic content work associated with the interaction. The system and method includes storing the received interaction information. The system and method also includes receiving a request from a second user requesting interaction information for a requested portion of the electronic content work. The system and method also includes sending the received interaction information in response to determining that the identification number associated with the received interaction information matches the identification in the request for interaction information.

Abstract: Systems and methods for creating, editing and publishing cross-platform interactive digital content works include a content management component configured to store portions of a digital content work and to implement version control of the digital content work; a defect tracking component configured to store a defect record related to a stored portion of the digital content work; a publication pipeline component configured to format the digital content work for publication; and a integration component configured to present a graphical user interface which allows for editing the stored portions of the digital content work, editing the defect record, and instructing the publication pipeline to format the digital content work for publication.

Abstract: Disclosed in some examples is a system for electronic learning support, the system having a content-ingestion module to generate a.

Abstract: A user interface for presenting a set of related pages of an electronic content work for view at the same time. The pages are sized according to a target format for presentation of the electronic content work, and may also be formatted according to user-defined font and zoom criteria. Each of the related pages comprises a media object, for example a markup language object. Responsive to user manipulation of presentation criterion for the set of related pages, the set of related pages is reformatted and so presented in near real-time. In some instances, a user may manipulate controls of the user interface to isolate a content object included within the set of related pages, have information regarding that content object presented and even edit the content object in-line with the present view.

Abstract: A user interface for a mobile computing device includes three distinct display areas, one for presentation of an image and one or more interactive elements, a second for display of a linearly scrollable sequence of content elements, each of which is associated with a corresponding one of the interactive elements, and a third for display of soft keys, each of which corresponds to a respective one of the interactive elements. The soft keys and the interactive elements are responsive to user input so as to cause the image displayed in the first display area to feature prominently a portion thereof corresponding to the interactive element associated with the user input and the content element displayed within the second display area to be that associated with the same interactive element.

Abstract: Disclosed in some examples are methods, systems, and machine readable mediums for creating and presenting an outline view, the outline view including a first user navigable graphical panel, the first panel displaying first organizational elements corresponding to a first outline level of an electronic content work; a second user navigable graphical panel, the second panel displaying one or more child organizational elements of a selected first organizational element, the child organizational elements corresponding to a second outline level of the electronic content work; and one or more content previews of content within the electronic content work in the first or second panel, the content previews corresponding to the first or second outline levels of the electronic content work, respectively.

Abstract: In one embodiment, a user of a first portable digital computing device creates an annotation associated with a particular reading location within a reference document. The annotation and the reading location are shared with a second portable digital computing device storing a copy of the reference document. Using the shared information, the second device displays the reference document with the annotation shown at the reading location.

Abstract: A system, computer-readable storage medium, and a computer-implemented method for associating two-dimensional objects with a three-dimensional model are presented. A three-dimensional model is rendered using a graphics API from a first position to a second position on a display of a user device in response to a user input and is associated with a two-dimensional object previously displayed, using native controls, in the first position prior to the user input. A first set of three-dimensional coordinates associated with the two-dimensional object in the first position is determined and transformed via the graphics API to a second set of three-dimensional coordinates associated with the two-dimensional object in the second position based on the user input. The two-dimensional object is displayed in the second position based on the second set of three-dimensional coordinates via the native controls.
