Abstract

The present invention provides for a presentation display system comprised of a display screen for displaying an electronic presentation and a presentation device configured to provide the electronic presentation. An input screen is coupled to the presentation device such that when a user enters a notation on the input screen the presentation device incorporates the notation into the electronic presentation. In addition, a projection unit can be coupled to the presentation device configured to project the electronic presentation onto the display screen, where the input screen is coupled to the projection unit such that when a user enters a notation on the input screen the projection unit incorporates the notation into the electronic presentation and projects the electronic presentation onto the display screen.

Claims
