Discusses the use of interface metaphors in computer system design. Describes empirical research that shows users can experience cognitive dissonance with metaphors and suggests that the concept of a logical analogue rather than that of a metaphor should guide system designers. (Contains 66 references.) (LRW)

Defines digital library collections and outlines two classes of collection metadata. Describes the Alexandria Digital Library (ADL) Project approach to collection metadata, including the ADL system architecture and collection guidelines and the format and use of the ADL collection metadata. Appendices include ADL collection metadata and example.…

Two controlled experiments examined whether the animated zooming effect accompanying the opening or closing of a folder in the Apple Macintosh graphical user interface aids in the user's perception of which window corresponds to which folder. Results suggest users may become attuned to the informational content of the zooming effect with…

Presents a framework for the design of information representations in terms of previews and overviews, to aid designers of digital library interfaces. Defines previews and overviews, as graphic or textual representations of information abstracted from primary information objects, analogous to bibliographic records and catalogs; and describes four…

Examines differences between the formal features of commercial versus noncommercial Web sites, and the relationship between Web page complexity and amount of traffic a site receives. Findings indicate that, although most pages in this stage of the Web's development remain technologically simple and noninteractive, there are significant…

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…

Results of two studies of user design preferences for link markers--entities that signify pathways to additional information in hypermedia information systems--indicate that, in general, link markers that employ color and bound objects are the most effective in communicating the existence and extent of links and are most preferred by users.…

Describes the Alexandria Digital Library, a geolibrary that focuses on geographical locations. Topics include the evolution of the system and interface design; design goals; user communities, including earth scientists, information specialists, and educators; user evaluation methodologies and findings; and future possibilities. (LRW)

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

Research in human-computer interaction is evolving a user-centered methodology for system design and instruction that focuses on integrating affective and cognitive user variables to increase productivity, creativity, and human growth. Discussion includes the survey approach, the experimental-ethnographic approach; theory-building; and the future…
