Describes a graphical user interface called IFM (Intelligent File Manipulator) that provides intelligent help to users. Explains two underlying reasoning mechanisms, one an adaptation of human plausible reasoning and one that performs goal recognition based on the effects of users' commands; and presents results of an empirical study that…

The development of safety-critical systems (aircraft cockpits and reactor control rooms) is qualitatively different from that of other interactive systems. These differences impose burdens on design teams that must ensure the development of human-machine interfaces. Analyzes strengths and weaknesses of formal methods for the design of user…

Presents an information visualization workspace in which users are able to explore data presented in diverse but coordinated formats using related systems called Visage, SAGE, and selective dynamic manipulation (SDM). Discusses four dimensions for analyzing user interfaces that reveal the combination of design approaches needed for visualizations…

Introduces five articles in a special journal issue devoted to research about, design of, and use of multimodal interfaces. Article highlights include: algebra instruction; presentation of data summaries; interaction with complex spatial displays (maps); access to computing for the visually impaired; and design for portable devices for use in…

Introduces a multiagent architecture based on the blackboard system that enables different processes that perform multimodal presentation planning to communicate with each other. Describes a constraint propagation mechanism that transfers plan constraints from one level of the presentation planning process to the next. Discusses the cooperation…
