  • System and method for electronic presentations with annotation of preview material
    Patent number: 7454708
    Abstract: An electronic presentation system and method provides multiple display screens for presentation materials as well as permits dynamic annotations to presentation materials that do not permanently alter the presentation materials. In a multi-windowed display interface, a currently displayed slide or the next-to-display slide can be easily annotated or otherwise modified. Thus, the presentation materials can easily be directed to any one of the display screens and any annotations can be saved for future use or simply deleted.
