Intelligent User Interfaces: An Introduction
Mark Maybury

Intelligent user interfaces (IUI) aim to improve human-machine interaction by representing, reasoning, and intelligently acting on models of the user, domain, task, discourse, and media (e.g., graphics, natural language, gesture). IUIs are multifaceted, in purpose and nature, and include capabilities for multimedia input analysis, multimedia presentation generation, and the use of user, discourse and task models to personalize and enhance interaction. Some IUIs support asynchronous, ambiguous, and inexact input through analysis of multimodal input. Others include animated computer agents that express system and discourse status via facial displays, that tailor explanations to particular contexts, or that manage dialogues between human and machine.

Potential IUI benefits include:

• More efficient interaction — enabling more rapid task completion with less work.
• More effective interaction — doing the right thing at the right time, tailoring the content and form of the interaction to the context of the user, task, dialogue
• More natural interaction — supporting human-like spoken, written, and gestural interaction.

Drawing upon material from Readings in Intelligent User Interfaces (Maybury and Wahlster, 1998) and subsequent research, this tutorial will define terms, outline the history, describe key subfields, and exemplify and demonstrate intelligent user interfaces in action.

Mark Maybury received his M.Phil. in Computer Speech and Language Processing, an MBA from RPI, and his Ph.D. in Artificial Intelligence for his dissertation, "Generating Multisentential Text using Communicative Acts" at Cambridge University. Mark has organised international symposia, given tutorials, and published over fifty articles in the area of language generation, multimedia presentation, text summarization, and intelligent information retrieval. Mark is editor of Intelligent Multimedia Interfaces (AAAI/MIT Press 1993), Intelligent Multimedia Information Retrieval (AAAI/ MIT Press 1997), New Directions in Question Answering (AAAI/ MIT Press 2004), co-editor of Readings on Intelligent User Interfaces (Morgan Kaufmann Press 1998), Advances in Text Summarization (MIT Press 1999), Advances in Knowledge Management (MIT Press 2001) and Personalized Digital Television (Kluwer Academic, 2004), and co-author of Information Storage and Retrieval (Kluwer Academic 2000). Mark is Executive Director of MITRE's Information Technology Division, a member of the ACM IUI Steering Committee and a member of the USAF Scientific Advisory Board.
