Introduces a special issue on research on hypertext systems and information retrieval. Systems design aspects, including navigation models, link weighting, multiple representation techniques, automatic authoring, user modelling, varying levels of abstraction, and evaluation techniques are addressed. (EA)

Describes performer-centric interface design and explains a model-based approach for conducting performer-centric analysis and design. Highlights include design methodology, including cognitive task analysis; creating task scenarios; creating the presentation model; creating storyboards; proof of concept screens; object models and icons;…

Describes "DesignStation 2000," a software and hardware workbench for laptop computers for the design of learning systems that includes capabilities for needs analysis; client presentation and proposal generation; rapid prototyping of interactive media projects; collaboration and project tracking; assessment of results; and adding to a…

Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

Discussion of the problem of control in documentary information retrieval (IR) systems focuses on feedback mechanisms. Information needs are discussed, particularly the Problem Oriented Information Need (POIN); the structure of an adaptive IR system is described; and the design of algorithms for automated IR systems is explained. (33 references)…

Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered. (30 references) (EA)

Presents an approach to developing viable image computer-human interactions (CHI) involving user metaphors for comprehending image data and methods for locating, accessing, and displaying computer images. A medical-image radiology workstation application is used as an example, and feedback and evaluation methods are discussed. (41 references) (LRW)

Describes computing access in public spaces (CAPS) and presents a case study of the U.S. Holocaust Memorial Museum (USHMM) Learning Center, including the design, implementation, and testing prior to its installation. Characteristics of CAPS are discussed, and guidelines for the USHMM Learning Center are explained. (Contains 11 references.) (LRW)

Describes the Drexel Hypermedia Demo, a hypermedia system that was developed to facilitate undergraduate and graduate instruction about hypermedia. Topics discussed include media advocacy; interactivity in educational media; navigation in hyperspace; learner control; and design principles and evaluation of the Drexel Hypermedia Demo, including…

Discusses problems in the use of performance support systems in higher education. The following issues are addressed (1) development, including software development, collaboration with users, and instructor skills; (2) access, including physical environment limitations; (3) training for students and faculty; (4) student resistance; (5) teaching…

Argues that there is a fundamental gap between the knowledge that the information systems development community values and that which cultural analysis yields. Suggests that developers, rather than trying to explain social behavior and knowledge with rules, should be concerned with the production of contesting rules and what the production tells…

Four articles respond to the Bader and Nyce position that it is unlikely cultural analysis will become a routine tool for information systems developers with these arguments: ethnographic work can aid software development; the problem lies with inappropriate application of social science methods; the problem is technique, not fundamentals; and…

Describes the design, implementation, and evaluation of a computer-assisted learning (CAL) package called CLEM (CORE Learning Environment for Modula-2) that was developed in Great Britain for teaching the Modula-2 programming language to first-year college students. Topics discussed include interactivity, flexibility, ease of use, student…
