Describes a knowledge management system that was developed to help provide structure for dynamic and static data and to aid in the analysis of complex experimentation. Topics include quantitative and qualitative data; mining operations using artificial intelligence techniques; information architecture of the system; and transforming data into…

Discusses software design issues for Okapi, an information retrieval system that incorporates both search engine and user interface and supports weighted searching, relevance feedback, and query expansion. The basic search system, adjacency searching, and moving toward a distributed system are discussed. (Author/LRW)

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…

Provides information on designing an effective and efficient computer user interface. Topics include determining an audience's mental model of the subject; creating effective navigation systems; components of the interface; what to consider when designing the interface; and the multimedia interface design process. (Author/LRW)

Presents a group of semiotic principles for software design and uses them to show how they explain different educational possibilities. Discusses interface design and describes Theater in the Computer, a software environment for children, to illustrate semiotic-based principle of interface design. (Author/LRW)

This paper discusses a generic query tool that enables an end user to query a metadata store through filters that impose search criteria on attributes. The Metadata Query Tool (MQT) is generic in the sense that it dynamically creates its user interface, based on configuration files that define the metadata scheme and the query functionalities.…

Discusses software design for enterprise systems and for video games, and describes difficulties with enterprise tools, including interface complexity, training costs, and user frustration. Examines the world of tools and games from the human perspective and suggests ways in which game design can be successfully transferred to the enterprise tool…

Explores the principles and theories relevant to the design of effective hypermedia courseware. Proposes a hypermedia design: micro-(node) design, dealing with the creation of discrete information screens; and macro-(links), dealing with the connections between them. Presents a prototype courseware template and a courseware unit based on design…

Identifies and describes methods of compiling datasets, search interfaces and etymological metaphors and mythologies of three of the first generation of automated indexing systems: archie, veronica, and robots and search engines. (Author/JKP)

Outlines the generic features of enterprise information portal applications, or corporate portals, which provide users with access to internal and external information resources through a customizable Web browser interface. Examines approaches being taken by vendors, many of whom are adapting software developed for document management and…

Discusses the development and introduction of expert tutoring systems (ETS), or intelligent tutoring systems. Explains MONAP-PLUS, an example of an authoring tool for the design of an ETS that includes models of the subject domain, the learner, and the learning process; a user-friendly interface; and techniques for developing algorithmic…

The graphical user interface (GUI) has become something of a standard for instructional programs in recent years. One type of GUI is the metaphorical type. For example, the Macintosh GUI is based on the "desktop" metaphor where objects one manipulates within the GUI are implied to be objects one might find in a real office's desktop.…

This final report contains a detailed description of six software systems designed to assist individuals with blindness and/or speech disorders in using inexpensive, off-the-shelf computers rather than expensive custom-made devices. The developed software is not written in the native machine language of any particular brand of computer, but in the…

This article describes the evolution of computer interface research issues from text-based interface design guidelines to more complex issues, including media selection, interface design, and visual design. This research is then integrated into the Analysis-based Message Design (AMD) process. The AMD process divides the interface design process…

Describes "Placemark," an online tool for creating and managing Web pages within a school or district Web site. Topics include interviews with teachers to determine their needs, which centered around creating instructional materials and activities; online newsletters for parents; feedback to test the interface; formative evaluation; and…
