Abstract: This disclosure describes systems, methods, and computer program products for authoring content for digital books. In some implementations, a single graphical user interface (GUI) is presented that allows an author to design a layout for the digital book, including editing text and inserting various types of interactive elements in the text. The GUI functions as both a digital book layout design tool and a word processor to facilitate the building of a digital book. The relative page location of inserted widgets can be determined by a user-selectable anchor point placed within the text. An outline view of the digital book can be created and presented in the GUI based on a hierarchical structure determined by paragraph styles applied to the text. The GUI can provide a hybrid glossary and index page for allowing the author to create and manage a glossary and index for the digital book.

Abstract: A graphical user interface (GUI) is presented that allows a user to view and interact with content embedded in a digital book, such as text, image galleries, multimedia presentations, video, HTML, animated and static diagrams, charts, tables, visual dictionaries, review questions, three-dimensional (3D) animation and any other known media content, and various touch gestures can be used by the user to move through images and multimedia presentations, play video, answer review questions, manipulate three-dimensional objects, and interact with HTML.

Abstract: This disclosure describes systems, methods, and computer program products for presenting interactive content for digital books. In some implementations, a graphical user interface (GUI) is presented that allows a user to view and interact with content embedded in a digital book. The interactive content can include, but is not limited to, text, image galleries, multimedia presentations, video, HTML, animated and static diagrams, charts, tables, visual dictionaries, review questions, three-dimensional (3D) animation and any other known media content. For example, various touch gestures can be used by the user to move through images and multimedia presentations, play video, answer review questions, manipulate three-dimensional objects, and interact with HTML.
