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

1. A presentation display system comprising:

a presentation device comprising a display screen for displaying an electronic presentation;

an input screen coupled to said presentation device such that when a presenter enters a notation on said input screen said presentation device incorporates said notation into said electronic presentation; and

a presentation network device configured to network a plurality of remote user nodes to said presentation device, said presentation network device being configured to provide electronic display information from said electronic presentation to each of said plurality of remote user nodes,

wherein said presentation network device is configured to provide said presentation device and said remote user nodes with added viewer notations added in conjunction with said electronic presentation at a respective input screen at any one of said remote user nodes such that said presentation device and each of said remote user nodes display said electronic presentation in combination with said added viewer notations; and

wherein said system includes means for providing a blank slide to one of the input screens, means for storing tentative notations made to that blank slide independent of said electronic presentation by the user of the blank slide, and means controlled by said user of the blank slide for discarding the tentative notations or saving the tentative notations and transmitting the tentative notations to the presentation network device.

2. A presentation display system as claimed in claim 1, further comprising a projection unit coupled to said presentation device configured to project said electronic presentation onto said display screen, wherein said projection unit is further comprised of:

an interface unit configured to interface said projection unit with said presentation device and said input screen;

a projection unit memory module; and

a projection unit processor, said projection unit processor configured to create an image formed from said incorporated notation and said electronic presentation.

3. The presentation display system as claimed in claim 1, wherein said presentation device is a Personal Computer (PC) configured to operate an electronic presentation program.

4. The presentation display system as claimed in claim 1, wherein said remote user nodes are links for attaching a personal viewing device to said presentation display system, said personal viewing devices being any one of a Personal Computer (PC), a handheld computer/organizer and a Notebook computer.

5. The presentation display system as claimed in claim 1, wherein said remote user nodes are personal viewing devices, said personal viewing devices being any one of a Personal Computer (PC), a handheld computer/organizer and a Notebook computer.

6. The presentation display system as claimed in claim 1, wherein any one of said remote user nodes are located in different geographic location from said presentation device, and remaining said remote user nodes.
