Abstract: A system and method for navigating secondary content. The system may monitor for gestures input to the system by an input device and may detect an arc gesture. The arc gesture may travel along both a horizontal axis and a vertical axis from a first point to a second point and may be delineated from a horizontal or a vertical motion. The system may identify secondary content corresponding to the arc gesture in response to the arc gesture and output data corresponding to the secondary content. The system may identify supplemental text associated with the secondary content and synthesize supplemental speech corresponding to the supplemental text. The output data may include audio including the synthesized supplemental speech.

Abstract: A method of creating a free-form visual user interface element includes receiving a command to associate a visual representation of at least one of a set of graphical user interface controller attributes with a free-form visual element, generating instructions defining the at least one of the set of graphical user interface controller attributes, and adapting the instructions to a data structure embodying the free-form visual element. The method also includes attaching the adapted instructions to the data structure to form a free-form visual user interface element.

Abstract: A system and method for adding audio indicators, such as an audio tone, to audio data corresponding to text. The audio indicator corresponds to secondary content in text, such as a footnote. The system will insert and/or modify a textual indicator at a location in the text corresponding to the secondary content. The system will then process the textual indicator during text-to-speech processing of the text so that an audio tone is output at a moment in speech data corresponding to the location of the secondary content in the text. A speech synthesis markup language may be used to create and/or modify the textual indicator.
