The 1998 IUI meeting is the fourth in a series of gatherings of the intelligent interfaces community. Started in 1988 in Monterey, California, it moved to Orlando, Florida in 1993, and, with IUI'97, it has become an annual event that provides a forum for outstanding research and development on intelligent user interfaces.

Scope
We seek high-quality, original papers, panels, and demonstrations that address the theory, design, development, and evaluation of intelligent user interfaces. Suggested topics include (but are not limited to):

• Knowledge-based tools and environments for user interface design and development.
• Plan-based interfaces and plan recognition.
• Automated presentation of information.
• Intelligent interfaces for the Internet, for tasks such as design, presentation, access, and navigation.
• Adaptive and customizable user interfaces.
• Intelligent agents and agent-based interaction.
• Architectures for intelligent, cooperative, distributed, and multimodal interfaces.
• Evaluation of intelligent and agent-based interfaces.
• Cognitive user modeling.
• Intelligent front-ends to interactive, multimedia, hypermedia, or knowledge-based systems.
• Application-specific intelligent interfaces, in areas such as tutoring, information retrieval, decision support, computer-supported cooperative work, computer-aided design, etc.

Submissions
Papers are solicited for presentations as talks, interactive posters, or demonstrations. Authors are encouraged to submit work-in-progress to the poster session. Longer papers should highlight both the general scientific contribution of the research and its practical significance. Panels are solicited that would provide controversial or stimulating debate on any of the topics relevant to the meeting. Papers for submission must be formatted using the CHI paper format. Full papers are limited to 8 pages. Short papers (to be presented as interactive poster presentations or demonstrations) are limited to 4 pages, and panels to 6 pages. Supporting videos (VHS) are encouraged for paper, poster, and demo submissions. All submissions must be sent to the Program Chair to arrive by July 1st, 1997.
