US Patent 7512887 Method to employ multiple, alternative presentations within a single presentation

A method of creating multiple, alternative presentations within a single electronic presentation, by assigning one or more presentation constraint parameters to the electronic slides, and generating a sequence for presenting less than all of the electronic slides based on the presentation constraint parameters. Different sequences can be generated using different presentation constraint parameters that are assigned to the electronic slides. For example, a first electronic slide could be included in a first sequence, and a second electronic slide (or multiple slides) can be substituted for the first electronic slide in a second sequence. A sequence can be generated by adjusting a scalable constraint associated with the presentation constraint parameters to determine which electronic slides to include. The presentation constraint parameters can include a time factor and a content level.
