Abstract: Systems and methods are provided for a server node to allow a first client node to follow a second client node in a collaboration session. The method includes sending at least a portion of a spatial event map to a first node wherein the spatial event map locates events in a virtual workspace. The method includes sending data to allow the first node to display, in a screen space of a display associated with the first node, digital assets identified by events in the spatial event map that have locations within a viewport of the first node. The method includes sending data to allow the first node to follow a second node by, in response to identification of a viewport change event in the spatial event map for the second node.

Abstract: A network node of a collaboration system is provided to establish communication with other network nodes. The network node comprises a display having a physical display space. The network node can store collaboration data and render on the local client screen space a local client canvas having locations in the virtual workspace. The network node includes logic to provide a user interface to display a list of markers representing predefined canvases in both the virtual workspace and another virtual workspace. The predefined canvases defining (i) respective areas in the virtual workspace having a location and (ii) an area in the other virtual workspace having a location. The network node includes logic to respond to an input indicating a selected marker from the list of displayed markers to update the location of the local client canvas to match the location of the predefined canvas represented by the selected marker.

Abstract: A spatial event map system including server-side data processor that maintains a 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 an object of the event in the workspace and a time. The system includes logic to send messages including a location of an object of the event in the workspace and a time of the event to client-side network nodes; and to receive messages identifying events that create or modify an object, and to add corresponding entries to the log of events. The events can include history events that are sent to the other client-side network nodes, and added to the log for the corresponding history events, and ephemeral events that are sent to other client-side network nodes without adding corresponding entries in the log.
