  • Publication number: 20020140724
    Abstract: A system and method for delivering a presentation electronically. The invention takes advantage of the multiple monitor capabilities of a computer operating system to display a “control panel” on the computer monitor or laptop screen that typically only the presenter will view. The presenter can use this control panel to view and control the presentation while the audience only sees a full screen slideshow. Providing this “presenter” view and control makes computer-based presenting much easier. The presenter can control the specific aspects of the slideshow from the private monitor using control buttons or keyboard shortcuts.
