Method to Compare Screen Sharing Target -to-Audience View

During a web-based meeting where the presenter is sharing their screen view with participants, a method is needed to indicate to the presenter that all participants can see the screen from their location. With such a notification system in the screen sharing application, a presenter would know when to start presenting or running a demonstration without have to stop and ask participants whether they can see the screen.

There is no known blocking art. Known solutions include manipulation of the main session, receiving conditions about a session, and sharing presentation information across different people for a remote screen-sharing session. This is not the intent of the disclosed invention.

Disclosed is a method to provide a notification back to the presenter that the participants in a screen-sharing application are able to see the intended presentation. The invention has the following main elements:


• A preview/snapshot screen of the intended view is provided to the participants as part of the presentation application


• Participants are able to see intended preview/snapshot screen on their client machines


• Analysis is performed to compare the preview/snapshot screen and intended screen (e.g., pixel, text/graphical patterns, etc.)


• The presentation application sends a response back to the presenter based on performed analysis


• The presenter receives feedback on how many participants can see the screen

Preferred Embodiment:


1. The presenter/host of the conference joins a remote conference application

2. The presentation application captures snapshots, at a lower-resolution, of each slide within the presentation material


3. Conference participants join a remote conference application

4. The application shows a snapshot in a portion of the remote conference application to participants so they have a sense of what they should be seeing on their screen
