The purpose of this experiment was to assess the effectiveness of a comprehensive model for the analysis of hypermap navigation patterns through a comparison of navigation patterns associated with a traditional linear interface versus a non-linear "hypermap" interface. Twenty-six general psychology university students studied material on bipolar…

This paper summarizes a subset of the findings of a study of digital image distribution that focused on the Museum Educational Site Licensing (MESL) project--the first large-scale multi-institutional project to explore digital delivery of art images and accompanying text/metadata from disparate sources. This Mellon Foundation-sponsored study…

This report discusses research commissioned by the Corporation for Public Broadcasting in order to evaluate prototypes of digital public television programming. There were two phases of research, the first using exclusively linear demonstrations of interactive public television, and the second demonstrating computer simulations of three digital…

The Informedia Project at Carnegie Mellon University has created a multi-terabyte digital video library consisting of thousands of hours of video, segmented into over 50,000 stories, or documents. Since Informedia's inception in 1994, numerous interfaces have been developed and tested for accessing this library, including work on multimedia…

This is a story about screen interactivity and its magical early influences. It includes a brief history of the evolution of the computer, with examples from contemporary applications in art and museum education. I believe it is important to know about the early days of drawing on the screen to get a sense of the continuum of ideas that has led us…

Describes a workshop that introduces participants to the UNIX operating system. Provides an overview of how to access information on the Internet and gain familiarity with Web browsers, file transfer programs, telnet sessions, newsreaders, and Gopher services. (DDR)

Digital libraries of the future will be shaped by the technologies, standards, and models adopted today. This article examines interoperability of library systems, metadata standards, copyright management, fair use, preservation of digital information, problems resulting from technological advancement, costs, print versus Web resources, and…

In the case of digital collections of text, provision of a simple unified user interface faces several challenges, among them a tension between intellectual adequacy and simplicity of access. Examines the question of how to allow cross-collection searching and display while preserving the variation in texts and their markup and points to…

Reports findings from an exploratory study investigating working notes created during encoding and external storage (EES) processes by human search intermediaries (librarians at the University of North Texas) using a Boolean information retrieval (IR) system. Implications for the design of IR interfaces and further research is discussed.…

Describes a titrator system, constructed from a computer-interfaced pH-meter, that was designed to increase student involvement in the process. Combines automatic data collection with real-time graphical display and interactive controls to focus attention on the process rather than on bits of data. Improves understanding of concepts and…

Discusses issues related to natural language processing, including theoretical developments; natural language understanding; tools and techniques; natural language text processing systems; abstracting; information extraction; information retrieval; interfaces; software; Internet, Web, and digital library applications; machine translation for…

This article identifies benefits of using Internet technologies in an organization's intranet or internal information system: ease-of-use, one interface, implementation cost, access, information services (flat content and interactive intranets), support desks (via Web services and e-mail), document management. Discusses the impact of intranets on…

Reviews issues relating to database technology and digital libraries. Highlights include resource sharing; ongoing digital library projects; metadata; user interfaces; query processing; interoperability; data quality; copyright infringement; and managerial implications, including electronic versus printed materials, accessibility,…

Addresses the cultural gap between teachers who are computer literate and those who are not. Highlights include traditional teaching methods; surface reasons for not using computers, including high cost, complexity, hostile interface, and rapid obsolescence; the opportunity for students to become independent lifelong learners with the Internet;…

Investigates the effects of two hypermedia interface design strategies on learner efficiency, perceptions of usability, and performance. Compares undergraduate student outcomes of comprehending and locating information by using manual and visual filtering via computers. Findings support the use of these filtering tools as methods of increasing…
