Abstract : As more and more machine intelligence is built into the interactive software tools of the future, the more the human-computer"dialogue" may come to resemble a true human-human dialogue, each party anticipating information needed by the other and avoiding rigid, repetitive or overly detailed exchanges by assuming the existence of a body of shared contextual knowledge. Although to humans dialogue means primarily natural language (NL) communication, friendly and effective human-computer dialogue should be able to take full advantage of an integrated mix of several different interaction modes including keyboard, speech, graphics, and body gestures. Context tracking would allow each input or output transaction to be minimally specific, deriving its full interpretation from background information relevant to the current topic of the interchange. The U.S. Navy has a particular interest in developing advanced user interfaces to such interactive knowledge-based tools as decision support systems, expert systems, and training aids. As a testbed for an initial investigation of integrated NL/graphical interfaces to such systems, we have been working for about a year now with a simulation-based test planning tool developed by Los Alamos National Laboratory for the Naval Air Systems Command.
