Abstract: A desktop display over a remote connection is updated by detecting, at their origin, changes in the desktop that reflect movement of an image, such as window scrolls, window moves and other movements of regions. For every frame of the desktop that is composed, moves can be detected. The offsets and regions of these moves are transformed into desktop space. A list of moves and other information about changed regions in the desktop display provide both an indication of moved image regions and move parameters, and image data that has otherwise changed. The moved image regions are moved at the destination by applying the move parameters, without transferring image data for the moved region to the remote device, while the remaining changed portion of the desktop is copied over the connection to the remote device.

Abstract: An improved application sharing system and method are described wherein a display of shared information is constructed such that application artifacts that are of no use to the viewer are not displayed to the viewer. In this way, a greatest possible portion of a viewing area can be used to display document content rather than such artifacts. In an embodiment, the functionality of reducing the display in this manner is engageable and disengageble by a viewing user. In a further embodiment of the invention, the functionality of reducing the display is automatically engaged and disengaged based on actions of a sharing user with respect to the shared information.

Abstract: An improved application sharing system and method are described wherein an application sharing viewing display is modified to increase the likelihood that a viewing user is able to see without scrolling the entirety of a window of interest displayed by a sharing user on a sharing machine. The scale of the viewer representation of the window of interest may be substantially continuously varied so as to best account for the particular size of the available display area at the viewing machine. In a further embodiment of the invention, the viewer's attention may be focused by filtering of the shared display material to visually enhance the current window of interest.

Abstract: An improved application sharing system and method are described wherein shared window data is treated according to different sets of rules depending upon the fraction of the shared window data that corresponds to the actual shared window. In this manner, occlusions of a shared window on a sharer display may be disguised or handled by a viewer display to minimize the impact of the occlusion on a viewing user, providing a more consistent and less confusing viewer experience.

Abstract: An improved application sharing system and method allow sharing of documents on a per document basis rather than on a per application basis, in order to simplify the user experience and to provide a more secure sharing environment. A window marking method is used to construct a window list describing the shared and unshared status of various windows. In an embodiment of the invention, a viewer machine displays only a most recently active shared document window even when other windows are also marked as shared. In this way, a viewer's attention can be automatically focused on a current document of interest.

Abstract: Disclosed are methods for remote users of a collaborative application to generate annotation information, send that annotation information to an application sharer device, and receive back a display combining output of the collaborative application with the annotation information. A collaborative application display is visible on an application viewer's screen. To make an annotation, a user draws over the shared display. The annotation is intercepted and sent to the sharer. On the sharer, the annotation is graphically blended with the display produced by the collaborative application. The combination is then sent to the remote viewers for display. The sharer may visually indicate, via color or a text flag, for example, the source of each annotation. The sharer may time out an annotation, or may delete the annotation if the collaborative application's display has scrolled underneath the annotation, causing the annotation to “lose its place” in the display and become meaningless.
