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 a graphical target of the event in the workspace and a time. The system includes logic to send messages including an event, a location of a graphical target of the event in the workspace and a time, to client-side network nodes; and to receive messages identifying events that create or modify a graphical target, 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.

Abstract: Systems and techniques are provided for monitoring a collaboration system. The system accumulates a log of entries to identify events in the collaboration workspace. An entry in the log of entries identifies an event and comprises data specifying virtual coordinates of location within the workspace at which an interaction with the workspace is detected, data identifying a type of interaction, a graphical object associated with the interaction, and a time of the interaction. The system assigns classifications to entries in the log according to the data identifying a type of interaction. The system displays a graphical construct as a function of the classifications of the entries in the log of entries.

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 method for invoking a procedure by a first network node in a computer system comprising the first network node and a second network node is provided. The method includes detecting a gesture or a user interaction event contacting a plurality of locations on a screen space of the first network node, obtaining an identification of a workflow procedure in dependence upon an interpretation of the gesture, the workflow procedure having an input parameter, mapping locations, included in the plurality of locations contacted by the gesture, to the location of the graphical object on the screen space, to obtain, from a data set, an identification of corresponding information associated with the graphical object, obtaining an identification of the input parameter of the identified workflow procedure in dependence upon the identified corresponding information, and invoking the identified workflow procedure according to the identified input parameter.

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.
