Discusses features of online public access catalogs: (1) demonstration of relationships between records; (2) provision of entry vocabularies; (3) arrangement of multiple entries on the screen; (4) provision of access points; (5) display of single records; and (6) division of catalogs into separate files or indexes. User studies and other research…

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)

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…

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…

Presents a four-stage hypothesis of information systems development based on computational capability, storage capability, communications capability, and effective voice input. Moore's Law and Mooers' Law are explained, the interface between the system and the user is discussed, and projections for the future are suggested. (21 references)…

This overview of MELVYL, the University of California's online union system, describes the databases included; network capabilities; software; distributed computing efforts; interfaces; new user needs, including integration with a user's environment, assistance in evaluating material, and assistance in evaluating resources; and the user community.…

Review of the 1991 literature on subject access in online systems discusses users and subject searching; subject access in online catalogs, including improvement of the database, search processing, the user interface, and user understanding; subject cataloging and indexing; information retrieval; thesaurus and indexing approaches; classification;…

Describes tracking tools used by designers and users to evaluate the efficacy of hypermedia systems. Highlights include human-computer interaction research; tracking tools and user-centered design; and three examples from the Interactive Multimedia Group at Cornell University that illustrate uses of various tracking tools. (27 references) (LRW)

Explores a user-centered approach to evaluating the Web search engine Inquirus. Inquirus was rated highly by users on various usability measures; all users experienced some level of shift/change in their information problem, information seeking, and personal knowledge due to their Inquirus interaction; and different users experienced different…

This examination of the effectiveness of various methods of cuing users to their location in a videotex information system used five different versions of an electronic edition of a college catalog: "simple" (no cues), "headers" (textual cues), "color" (color cues), "icons" (graphic cues), and…

This paper presents user perspectives on the future of the Internet. The first section discusses understanding users, including the difference between technology service offerings and potential uses, the need for investigation into the relationship between new communications technology and social behavior, and the shift from supply-led development…

Digital libraries are moving from research and development into commercial use. If they are to realize their full potential, however, the experiences of end users need to be taken into account from the earliest stages of design. Those end users are typically individuals who have no particular skills in information retrieval, and are accessing…

Presents a stratified model of information retrieval interaction that views interaction as a dialog between participants (user and computer) through an interface. Discusses traditional and interaction models, and extension to relevance, user modeling, search term selection, and types of feedback in information retrieval. (AEF)

Explores the systemological approach of dialogism as a new way of couching the problem of person-machine dialog in human-computer interaction. Concludes that a human-computer interaction community reflecting upon the future of interface will gain bona fide self-awareness from conceptualizing the machine as a component of society, rather than a…

Describes the Book House, an interactive, multimedia online public access catalog (OPAC) developed in Denmark that uses icons, text, and animation. An alternative design model that addresses problems in OPACs is described; and database design, system navigation, use for fiction retrieval, and evaluation are discussed. (20 references) (MES)
