Interactive user interfaces for electronic textbook implementations

Abstract

An interactive graphical user interface for navigating an electronic textbook includes nodes and connectors connecting the nodes. The nodes may correspond to items of educational content, and the connectors may correspond to a plurality of paths through the nodes. As a user navigates through the electronic textbook, the user may be presented with a custom map of the electronic textbook. A path of traversal may be permanently stored.

1 . A system for presenting an interactive graphical user interface on a display for navigating an electronic book, comprising:
 a panorama module, configured to present a page from the electronic book in a first view of the interactive user interface   
       (i) a panorama comprising a sequential plurality of features from the page in a background layer of the first view, and 
       (ii) one or more features of the sequential plurality of features from the page, in a foreground layer of the first view, to evoke acute-focus vision, wherein the one or more features presented in the foreground layer are enlarged from the panorama relative to the background layer; and
 a context gatherer module, configured to simultaneously present and highlight in a second view of the interactive user interface that is adjacent to the first view, one or more context features selected from a plurality of context features of the electronic book, wherein the one or more context features correspond to the one or more features displayed in the foreground layer in the first view of the interactive user interface. 
 
     
     
         2 . The system of  claim 1 , wherein the panorama module is configured to present the first view on a first display and wherein the context gatherer module is configured to present the second view on a second display different from the first display. 
     
     
         3 . The system of  claim 1 , further comprising a control panel module configured to display a plurality of sequence events, wherein a sequence event of the plurality of sequence events corresponds to a feature of the plurality of features or a step between two features of the plurality of features. 
     
     
         4 . The system of  claim 3 , wherein the plurality of sequences are displayed as a tabular grid. 
     
     
         5 . The system of  claim 3 , wherein the sequence event corresponds to a panorama event presented on the first view. 
     
     
         6 . The system of  claim 5 , wherein the panorama event comprises highlighting of the feature in the foreground layer of the first view. 
     
     
         7 . The system of  claim 1 , wherein the sequential plurality of features are further arranged in a plurality of clusters of features.
