VITAL (Vision Impaired Task and Assignment Lexicon) is an integrated computerized system that performs workplace design tasks for visually impaired workers. VITAL consists of three modules: ergonomics consultation, disability index, and work measurement. Evaluation indicated that VITAL could be used as a tool to help nonprofessional vocational…

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)

Discusses electronic collaboratories, where users can perform research without regard to geographical location. Based largely on experiences with the Upper Atmospheric Research Collaboratory (UARC), highlights include computer software, interactivity, corporate possibilities, behavioral science considerations, Internet performance, and the…

Discussion of the interaction between students and computers focuses on an evaluation of simulation-based learning with medical students in order to develop a framework for a dialog-based support system. It is based on a dialog analysis that employs transactional analysis and logical dialog game theory. (Author/LRW)

The design of five experiments comparing usability evaluation methods (UEMs) is examined. Each has had an important influence on human-computer interaction (HCI); however, problems with experimental design raised questions as to the efficacy of various UEMs. To obtain desired outcomes of the experimental method addressing HCI issues, close…

Reports on a qualitative study that explored strategies and behaviors of public library users during interaction with an online public access catalog, and users' confidence in finding needed information online. Discusses results of questionnaires, interviews, and observations that examined unknown-item searches, area searches, and known-item…

Discussion of user problems with navigating large spaces in virtual information environments focuses on a top-down application of semantic knowledge by the user from experiences within the sociocognitive context of information production and consumption. Considers individual differences in studies of interaction; spatial and semantic cues; and…

Proposes a framework for commercial Web application development based on prior research in hypermedia and human-computer interfaces. First, its social acceptability is investigated. Next, economic, technical, operational, and organizational viability are examined. For Web-page design, the functionality and usability of Web pages are considered.…

This research examined the communication process between users and online catalogs by gathering empirical data about user performance on different types of online catalogs. An experiment was designed to test whether content and layout of bibliographic displays influenced effectiveness of the interface between online catalogs and users. Data are…

Considers the relevance of human-computer interaction (HCI) guidelines for educational interface design, including why educational software is different from other products; differences in goal focus; performance and learning; and experiments that investigated transfer of learning, including implications for the design of educational technologies.…

Explores the future of reference librarianship within the context of the enabling technologies that will chart library development in the 21st century. The article types libraries into categories of "traditional,""automated,""hybrid," and "digital." The typology delineates shifts in human/machine…

Examines the growth in developing performance-centered systems in business. Discusses Web-based systems, including the Internet and intranets; knowledge management systems; knowledge acquisition; performance-centered design; performance support; group processes; systems approach; focus on goals; electronic performance support systems;…

Explores the concepts of interaction and interactivity presented in different theoretical models in the fields of human-computer interaction (HCI) and information-seeking/searching behavior, and relates these to information retrieval (IR) research. Suggests that interaction in HCI is primarily concerned with establishing a user/system dialogue at…

Provides an in-depth introduction to the various technologies that are bringing intelligent agents into the forefront of information technology, explaining how such agents work, the standards involved, and how agent-based applications can be developed. (Author/AEF)

The objective in this paper is the implementation of the highly structured seven-step problem-based learning (PBL) procedure as part of the learning process in a human-computer interaction (HCI) design course at the Technical University of Denmark, taking into account the common learning processes in PBL and the interaction design process. These…
