Abstract: An information presentation device for presenting information to a user is described, which is arranged to receive information transmissions from a remote information source, and comprises: an information transmission receiver for receiving information transmissions, an information extractor for extracting presentation information to be presented, from an information transmission, an information presenter for presenting the extracted presentation information, wherein a monitor is arranged to monitor the operation of one or more of the information extractor and the information presenter, determine whether the operation of one or more of the information extractor and the information presenter fulfils one or more predetermined conditions, and generate an operation condition signal destined for the remote information source, said operation condition signal conveying an indication of the fulfillment or non-fulfillment of said one or more conditions.

Abstract: A graphical user interface includes at least one primary window that displays the contents of a hierarchical data model as a hierarchical tree. A secondary window is displayed which contains a subset of the contents, e.g., groupings based on search criteria, of the hierarchical data model as a flat-list. The primary window and the secondary window are displayed on a screen at the same time so that a user can see both the hierarchical relationship and specific groupings of the contents of the hierarchical data model. Several synchronization mechanisms between the primary window and the secondary window are provided. For example, a user can select an element of the flat-list in the secondary window and cause the display of the primary window to correspond to the user's selection of the element. In addition, multiple selected elements from the secondary window can be copied back to the primary window such that a common operation can be performed on the multiple selected elements.
