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. A backrest arrangement may extend from the seat assembly. In the lowered position, the front and rear seat parts are both generally horizontally oriented. In the elevated position, the rear seat part may have a slight forward tilt and be positioned higher than in the lowered position, and the front seat part may extend at a downward angle relative to the rear seat part.

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: An office-type chair including a back support having a suspension mesh back support and a back support frame. The suspension mesh back support has an integral retaining channel disposed at a peripheral edge thereof, and the back support frame includes a central pair of upright support posts and wedge base for mounting to a chair frame. The back support frame includes a plurality of flexible and spaced support arms extending laterally outward from the upright support posts. The support arms each have a peripheral edge configured for fastenerless attachment in a tensioned state within the suspension mesh retaining channel. An upholstery cover encapsulates the suspension mesh and back support frame. The office chair also includes a lumbar mechanism including a resilient cushion that may be positioned in the space between the suspension mesh and the support frame and adjusted along the vertical extent of the back support by rolling the resilient cushion on the rear of the suspension mesh.

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.
