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: Systems and methods are provided for controlling display of a workspace. The system includes logic to establish a first level authorization at a display client enabling access to a workspace data set. The workspace data set can have a plurality of entries identifying respective digital assets and locations in the workspace for graphical objects representing the respective digital assets. The plurality of entries can include a particular entry identifying a particular digital asset requiring a second level authorization. The system includes logic to render, for the particular entry, a placeholder graphical object and a prompt. The system includes logic to detect user input indicating selection of the prompt, and in response executing a protocol to establish the second level authorization. Upon establishment of the second level authorization the placeholder graphical object is replaced with a second graphical object to reveal content of the particular digital asset.

Abstract: Systems and techniques are provided for synchronizing playback of a video at a plurality of client-side nodes in a network including a server-side node and the plurality of client-side nodes. The system includes logic to receive a sync video message at the server from a first client-side node identifying a sync event time. The system includes logic to map the sync event time at the server to a sync frame identifier. The server sends a follower sync video message to a follower set of one or more other client-side nodes including the sync frame identifier. In response to the follower sync video message the one or more client-side nodes in the follower set can synchronize playing the video at a frame corresponding to the sync frame identifier.

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: 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: 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: An office-type chair includes a base, a height-adjustable pedestal extending upward from the base, a seat assembly including a rear seat part and a front seat part, and a linkage system connecting the pedestal to the seat assembly. The linkage system is adapted to pivot the seat assembly between a lowered position to serve as a task chair and an elevated position to serve as an elevated sitting support.
