Methods for computing a navigation path

A method comprising:

• receiving a visual document element of a document;
• computing a time attribute for the visual element by:
• determining any necessary pan and zoom operations;
• and
• determining a time required to perform the operations based on one or more resolutions at which the operations are performed.

An article of manufacture having one or more recordable media with instructions thereon which, when executed by a system, cause the system to perform a method comprising:

• receiving a visual text document element of a document;
• computing a time attribute for the visual text element by:
• determining any necessary pan and zoom operations;
• and
• determining a time required to perform the operations based on one or more resolutions at which the operations are performed.

A method comprising:

• receiving a visual document element of a document;
• computing a time attribute for the visual element by
• performing a zoom operation to a minimal readable character height;
• checking width of the element to determine whether the elements fit the display width;
• performing a panning operation if the element width doesn't fit in the display width.

A method comprising:

• receiving a visual document element of a document;
• computing a time attribute for the visual element by
• performing a zoom operation to a first view;
• performing panning if the element is not completely visible.

A method comprising:

• receiving audible, visual, and audiovisual document elements;
• selecting either a combination of the visual and audiovisual document elements or a combination of the audible and audiovisual document elements for inclusion in a multimedia representation of the document based on the time and information content attributes;
• selecting a first set to maximize information contained in set subject to a given time constraint;
• and
• selecting a second set to maximize information contained in set subject to an amount of time remaining to complete the multimedia representation after maximizing the selected document elements.

An article of manufacture having one or more recordable media with instructions thereon which, when executed by a system, cause the system to perform a method comprising:

• receiving audible, visual, and audiovisual document elements;
• selecting either a combination of the visual and audiovisual document elements or the audible document elements for inclusion in a multimedia representation of the document based on the time and information content attributes;
• selecting a first set of document elements with respect to maximizing information contained in first set subject to a given time constraint;
• and
• selecting a second set of document elements with respect to maximizing information contained in the second set subject to an amount of time remaining to complete the multimedia representation after maximizing the selected document elements.

A method comprising:

• receiving audio and visual elements;
• determining audio and visual focus points;
• selecting audiovisual elements;
• and
• creating a navigation path for a presentation in a preset time in a constrained display area based on selected audiovisual elements and a combination of the audio and visual elements not part of the selected audiovisual elements.

An apparatus comprising:

• an input to receive audio and visual elements;
• an audio and visual focus point determiner to determine audio and visual focus points;
• an audiovisual element selector to select audiovisual elements;
• and
• a navigation path creator to create a navigation path for a presentation in a preset time in a constrained display area based on selected audiovisual elements and a combination of the audio and visual elements not part of the selected audiovisual elements.
