Describes the "Online Journal of Current Clinical Trials," a joint venture of OCLC and the American Association for the Advancement of Science that is the first electronic peer-reviewed science journal with graphics and searchable full text. Topics discussed include library automation, document delivery, benefits of electronic journals,…

Describes the design and development of the Mercury Electronic Library Project at Carnegie Mellon University that resulted in a library information system that provides access to the library's online catalog as well as to other databases. The distributed architecture of the system is explained, and future plans are discussed. (two references) (LRW)

Describes 12 constraints imposed by culture on educational software portability. Nielsen's seven-level virtual protocol model of human-computer interaction is discussed as a framework for considering the constraints, a hypothetical example of adapting software for Mexico is included, and suggestions for overcoming constraints and making software…

Describes the redesign of a CD-ROM database interface by the Congressional Information Service (CIS) that addressed the needs of novice, casual, and expert searchers in academic libraries. Topics discussed include the user profile, the task profile, redesign goals, interaction style, menu design and implementation, system structure and the search…

Defines playfulness in human-computer interactions in terms of flow theory and explores the dimensionality of the flow concept. Two studies are reported that investigated the factor structure and correlates of flow in human-computer interactions: one examined MBA students using Lotus 1-2-3 spreadsheet software, and one examined employees using…

Discussion of human/system interactions that are fundamental to online searching focuses on studies that examined online searchers' performance on DIALOG when they searched specific users' questions. Cognitive tests that were given to searchers are described; and calculating the odds for relevance, precision, and recall is explained. (four…

Discussion of issues involved in planning a multimedia CD-ROM product explains the selection of authoring tools, the design of a user interface, expert systems, text conversion and capture (including scanning and optical character recognition), and problems associated with image files. The use of audio is also discussed, and a 14-item glossary is…

Human-computer interface design concepts are used as the criteria for evaluating the benefits and shortcomings of San Diego State University Library's online catalog, INNOPAC (the PAC). Features discussed include integrated files, search capabilities, system availability, user interface, record-to-record links, boolean operations, subject access,…

Introduces a vision for how a multimedia learning system might work, and describes the design parameters involved in developing the EyeCue System, a large-scale interdisciplinary research-and-development project under development at North Carolina State University. (AEF)

Discusses individual differences between users of information systems that can influence search performance, and describes two experiments that addressed user-centered design of information systems. Highlights include interaction between cognitive abilities and design features; compensation and capitalization perspectives; recall and precision;…

Presents two empirical case studies concerning the role of individual differences in searching through a spatial-semantic virtual environment. Discusses information visualization in information systems; cognitive factors, including associative memory, spatial ability, and visual memory; user satisfaction; and cognitive abilities and search…

Summarizes reports and activities at the Information Infrastructure Technology and Applications workshop on digital libraries (Reston, Virginia, August 22, 1995). Defines digital library roles and identifies areas of needed research, including: interoperability; protocols for digital objects; collection management; interface design; human-computer…

Proposes a user-centered framework for intranet design based on an understanding of people, their typical problems, information behaviors, and situated contexts. Argues that by adopting such an approach, intranets can be designed which facilitate organizational information access and use. (Author/AEF)

Considers the impact of the Internet and online courses on learning and teaching. Topics include cost-benefit issues; learning styles; teaching styles; satisfying student needs; continuous evaluation for quality assurance; technological issues; active learning and collaborative learning; interactivity; and online course content. (LRW)

Although most interactive systems seem to facilitate user work, the system described--an interactive examination system--increased the time required by as much as 100 percent. Students taking an exam interactively and on paper were videotaped. Analysis showed the extra time went to system overhead, think time, and trouble understanding what to do.…
