Abstract: A collaboration system is provided and includes memory storing collaboration data including a spatial event map locating events in a virtual workspace and a local display including a screen space. The collaboration system further includes logic to identify a local client viewport in the virtual workspace, logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the local client viewport, logic to change a location and a dimension of the local client viewport in the virtual workspace in response to input signals, logic to render, in the screen space on the local display, graphical objects identified by events in the spatial event map that have locations within the changed local client viewport, and logic to generate a viewport change event in response to the change of the local client viewport in response to input signals.

Abstract: A collaboration system can be configured to support a large number of active clients in a workspace where the workspace is distributed into disparate groups of objects. While participating in the workspace, a first active client can configure their viewport to follow the viewport of a second active client. This configuration synchronizes the first active client's viewport with the second active client's viewport, including a translation or a zoom of the second active client's viewport. The system can be configured so that the second active client is informed that it is being followed by the first active client.

Abstract: A collaboration system including a spatial event map that can be published as an electronic document by a collaboration server and consumed by a consuming workstation. The electronic document is self-contained, and includes a viewer that has a module for rendering each of the graphical target types in the workspace onto a screen space. The system includes a server-side data processor that maintains the spatial event map which locates events in a workspace. The spatial event map includes a log of events, entries in the log having a location of a graphical target of the event in the workspace and a time.

Abstract: A node of a collaboration system is provided to establish communication with other nodes, store data identifying graphical targets having locations in a virtual workspace and including locations in the virtual workspace of the identified graphical targets, and compute a mapping of a local client viewport to a local client screen space. The node is configured to render on the local client screen space graphical targets having locations within the local client viewport, provide a user interface to display a list of viewport markers representing viewports, where each viewport defines an area in the workspace, and respond to an input indicating a selected viewport marker from the list of viewport markers, update the local client viewport to match the location and dimensions of the viewport represented by the selected viewport marker, and render on the local client screen space graphical targets having locations within the updated local client viewport.

Abstract: A collaboration system can be configured to support a large number of active clients in a workspace where the workspace is distributed into disparate groups of objects. While participating in the workspace, a first active client can display and search a list of location markers, and in response to selection of location markers, update their viewport to the location of a selected marker, without changing a zoom level. The system can be configured so that active clients are informed of creation and movement of location markers.
