Describes a study that investigated users' perceptions of ease of use versus user control in Web-based online information retrieval (IR) systems. Discusses desired features and functionalities as well as desired interface structures that support both ease of use and user control. (Author/LRW)

This paper discusses findings and data analysis issues that resulted from a case usability test. The case usability test was conducted as part of a redesign project that aimed to update the existing home page of Indiana University Bloomington. The home page contained links to the Web sites that various institutions in the university had already…

Investigates Web site design factors and their impact from a theoretical perspective. Presents a two-factor model that can guide Web site design and evaluation. According to the model, there are two types of design factors: hygiene and motivator. Results showed that the two-factor model provides a means for Web-user interface studies. Provides…

Describes a study where 66 subjects were asked to perform some predefined book purchasing task in a series of Web sites with varying interface quality. A strong relationship between interface quality and trust was found and some components of user interface quality were more important than others. Discusses implications for Web site design.…

Findings from a study of users' multitasking searches on Web search engines include: multitasking searches are a noticeable user behavior; multitasking search sessions are longer than regular search sessions in terms of queries per session and duration; both Excite and AlltheWeb.com users search for about three topics per multitasking session and…

As the Web becomes more popular, the interest in effective navigation is increasing. Menu design is becoming a critical issue of human computer interface design as the focus of computer applications moves from the computer as a machine to the human as a user. The purpose of this study was to investigate the effect of three different Web menu…

Describes how user interfaces for the Bureau of Labor Statistics (BLS) web site evolved over a 5-year period along with the larger organizational interface and how this co-evolution has influenced the institution. Interviews with BLS staff and transaction log analysis are the foci of this study, as well as user information-seeking studies and user…

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…

Results from user studies support the importance of genre and task in interface design and effectiveness of filtering of electronic news. Preliminary results from a study on effectiveness of predicting interesting Web pages based on the content of previously visited pages suggest a great similarity between reading electronic news and browsing the…

Presents a World Wide Web page model that reacts to pre-defined events and performs actions like "prefetching" automatically. Discusses the active index, conceptual page model; design of the client system, status of the current implementation, prefetching algorithm, an experiment of the algorithm, experimental results of the active index…

The development of potentially powerful computer-based tools within rich learning environments is hampered by the constraints of delivery systems (specifically low-resolution, low-real estate displays). In designing a World Wide Web-based tool for manipulating time-based information, the authors have encountered a lack of guidelines or empirical…

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 a study of graduate students that examined how Web interfaces impact the quality or outcome of online searches, as well as the information seeking behavior of the searcher. Examines how two search interfaces work to noticeably increase or decrease the impact of the emotive aspects of search behavior. (LRW)

Discussion of the effectiveness of distance education focuses on Moore's Theory of Transactional Distance and a study of learners' experiences with the World Wide Web in a university course in Taiwan. Highlights include learner-instructor interaction; learner-content interaction; learner-learner interaction; learner-interface interaction; results…

This survey examined the home pages of 36 Australian university library World Wide Web sites. Reports were run on these pages, using a service that checks the HTML for validity and reports errors, a service that checks usability by the visually disabled, and a program that checks the HTML, corrects and reports errors, and improves efficiency style…
