Abstract
A method of operation of a computer system for processing an arbitrary document such as a World Wide Web page to provide additional information not immediately available from the raw, unprocessed document. This additional information allows a user to navigate and control the content of the document using, in some embodiments, voice commands and/or an agent-based user interface. The present disclosure provides both a visual display of previously invisible links embedded in a web page image and an audible indication of the presence of such links. The present invention further comprises a scripting language that allows the rapid creation of executable computer instructions (or scripts) for controlling the behaviors and functionality of the agent-based interface. Such scripts enable the creation of a friendlier, easy to use interface to the navigation and control features. The present invention also comprises the ability to read the contents of an arbitrary web page aloud, including the names of embedded hypertext links, thus facilitating web surfing by the sightless.
