Distance learning networks make training and advanced education possible when time and budgetary constraints make face-to-face training difficult. To make distance learning work, instructors and providers must harness the potential of synchronous and asynchronous communication technologies to create powerful, learner-centered networks. Support…

This article uses the example of a single training course to show how to incorporate human factors into the interactive multimedia courseware development process. Three types of testing to identify human factors issues in courseware are discussed: usability testing, pilot testing, and field testing. (Author/LRW)

Reviews the literature on the use of Web search engines in information science research, including: ways users interact with Web search engines; social aspects of searching; structure and dynamic nature of the Web; link analysis; other bibliometric applications; characterizing information on the Web; search engine evaluation and improvement; and…

Discusses the use of microcomputer-based workstations that are provided for public access in libraries. Criteria for workstations are discussed, including standard hardware, open-design software, scalable interface, and connectivity options for networking; systems that provide full-text access are described; and the need for standards is…

Discusses the need for a rich semantics for the user interface in interactive image retrieval and presents two methods for building such interfaces: possibility theory applied to fuzzy data retrieval, and a machine learning technique applied to learning the user's deep need. Prototypes developed using videodisks and knowledge-based software are…

Describes a study that compared the effectiveness of screen designs for system interfaces by tallying keyboarding errors during online searches. The methodology is described as an unobtrusive means for obtaining objective and empirically based data for interface comparisons. A questionnaire used to determine users' reactions to screen designs is…

The first of two papers describes the rewriting of the DIALOG system software for DIALOG Version 2, and discusses both software and user interface issues. The second describes the development of Canadian produced scientific and technical databases and discusses issues concerning user training. (CLB)

The first of three articles on the design of user interfaces for information retrieval systems discusses the need to examine types of display, prompting, and input as separate entities. The second examines the use of artificial intelligence in creating natural language interfaces, and the third outlines standards for case studies in human computer…

Reviews the background, concepts, and role of hypermedia systems and analyzes essential, expected, and desirable features of hypermedia in order to provide a basis for system design and evaluation. Four hypermedium shells and systems are described, and approaches to user interface problems are discussed. (48 references) (MES)

Describes an online system originally designed to assist freshman writers develop research skills. The system incorporates a desktop approach to information management, using Apple Computer's HyperCard, in which students have access to a dynamic notebook and linked reference materials. Online searching in a hypertext environment is described. (CLB)

Examines current research on the implications of and the potential for two speech technologies: speech synthesis or response, i.e., speech output from a computer; and speech recognition, i.e., speech input to a computer. Human factors research is discussed; library applications are described; and future possibilities are considered. (Contains 148…

Highlights of this overview of virtual reality include optics; interface devices; virtual worlds; potential applications, including medicine and archaeology; problems, including costs; current research and development; future possibilities; and a listing of vendors and suppliers of virtual reality products. (Contains 11 references.) (LRW)

Provides an overview of CD-ROM networks. Highlights include network technology, including local area networks; an example of an installation at the South Bank Polytechnic (United Kingdom) library; interface issues, including standardization; possible future developments; licensing arrangements; and acquiring data in formats other than CD-ROM.…

Discusses general issues of computer and human understanding; contrasts three paradigms of information retrieval methodology, including statistical, deep semantic or natural language, and smart Boolean; describes CONIT, a knowledge-based intermediary retrieval assistance system; and examines system evaluation procedures, including a…

Synthesizes major findings from research on the magnitude of individual differences in information retrieval (IR) tasks and suggests implications for practice and design of IR systems and interfaces. Topics discussed include indexing consistency, relevance judgments, selection of subject headings, selection of search terms, and search retrievals.…
