Screen sharing method with selective access to both data and logic of a shared application using a helper application

摘要

A screen sharing system that enables selective access to application data and application logic is described. This screen sharing system is implemented by coupling a helper application (36) to an application that provides content referred to as content application (35). The helper application is an application that has the ability to programmatically access the content application (35) using window system graphical user interface application programming interface. Helper application (36) is used to get and set content application data and interact with the content application using window system input events that simulate user input. This method enables selective access to both application data and application logic that is necessary for use in a screen sharing system used by participants that may be trusted or may not be fully trusted.
