Abstract: An interactive data interpretation tool is disclosed for enabling the identification of the position of features in a multidimensional data set, the tool comprising means for displaying an image representing a 2-D slice of the data set; and user input means for causing the storage of the position of a feature in the displayed image, characterized in that the 2-D slice can be displayed as part of a projection of a 3-D image, the third dimension of which corresponds to one of the other dimensions of the data set, the tool comprising means operable in response to a predetermined user input operation to cause the co-ordinate of the currently displayed 2-D slice in the third dimension of the 3-D image to be incremented, and the positions in the 3-D image of any features identified in the previously displayed slice to be indicated. The invention finds particular application to the interpretation of seismological data sets. Other applications include oceanographic and medical imaging data sets.

Abstract: A method for defining an area of a computer screen (10). The defined area is specified as box (15) which the user may rigidly move vertically and horizontally and adjust both the width and height of the box (15). A single keystroke and motion of a mouse is sufficient to define the box (15), to resize the box (15) and to rigidly move the box (15).

Abstract: Method and system are provided for graphically displaying status information from alarm message generated during outages of a network such as a Common Channel Signaling (CCS) Network. The method and system include play, search, stop, filter, and pause features to efficiently analyze network-wide CCS events. In this way, the information is logically shrunk to a manageable size without losing information important to engineer and administer the network.

Abstract: A method and apparatus provide a direct manipulation protocol to allow a user, while dragging a source object to a target object, to pass the source object through one or more intervening processor objects, causing an appropriate action to occur to the source object when it is dropped on the target object. If the source object is passed across a processor object for which no appropriate action occurs, the source object remains unchanged in appearance and content. If the source object undergoes modification, its graphical representation to the user changes, giving the user feedback that the source object has been modified.
