System and method for visualizing and navigating content in a graphical user interface
View Patent ↗A system and method for visualizing and navigating document content using a condensed representation of a document to provide both a global overview of the distribution of key search terms as well as their immediate context. The invention supports rapid skimming of documents and document collections and enables efficient information finding, in some cases entirely eliminating the need to scroll within a document as with a conventional browser tool. The invention is of particular utility with personal digital assistants, which generally have small displays and limited storage capacity and communication bandwidth in comparison to personal computers. Documents may include conventional text and image files, web pages, audio files, and video files. The invention may also apply to collections of documents.
1. A method for visualizing and navigating documents in a graphical user interface comprising:
generating a summary view of at least one document containing instances of search terms using a condensed abstract representation depicting a search term density distribution;
triggering an enhancement of said summary view by cursor brushing; and
navigating to at least one segment of said document by selecting a corresponding portion of said summary view;
generating document metadata including at least one of: results of a speaker change search, results of a stress analysis, results of a speech transcript search, audio features, audio amplitude data, number of accesses to a particular document segment; and
depicting said search term density distribution using said document metadata.
