Abstract

The "Screen Design Manual" provides designers of interactive media with a practical working guide for preparing and presenting information that is suitable for both their target groups and the media they are using. It describes background information and relationships, clarifies them with the help of examples, and encourages further development of the language of digital media. In addition to the basics of the psychology of perception and learning, ergonomics, communication theory, imagery research, and aesthetics, the book also explores the design of navigation and orientation elements. Guidelines and checklists, along with the unique presentation of the book, support the application of information in practice.

Abstract

Recent research highlights the potential relevance of emotions in interface design. People can no longer be modeled as purely goal-driven, task-solving agents: They also have affective motivations for their choices and behavior implying an extended mandate for search design. Absent from current Web design practice, however, is a pattern for emotive criticism and design reflecting these new directions. Further, discussion of emotions and Web design is not limited to visual design or aesthetic appeal: Emotions users have as they interact with information also have design implications. The author outlines a framework for understanding users' emotional states as they seek information on the Web. It is inspired largely by Carol Kuhlthau's (1991, 1993, 1999) work in library services, particularly her information searching process (ISP), which is adapted to Web design practice. A staged approach resembling traditional models of information seeking behavior is presented here as the basis for creating appropriate search and navigation systems. This user-centered framework is flexible and solution-oriented, enjoys longevity, and considers affective factors. Its aim is a more comprehensive, conceptual analysis of the user's entire information search experience.

Abstract

The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

Abstract

Visual Interfaces to Digital Libraries exploit the power of human vision and spatial cognition to help individuals mentally organize and electronically access and manage large and complex information spaces. They draw on progress in the field of information visualization and seek to shift the users' mental load from slow reading to faster perceptual processes such as visual pattern recognition.Based on two workshops, the book presents an introductory overview as well as a closing listing of the top ten problems in the area by the volume editors. Also included are 16 thoroughly reviewed and revised full papers organized in topical sections on visual interfaces to documents, document parts, document variants, and document usage data; visual interfaces to image and video documents; visualization of knowledge domains; cartographic interfaces to digital libraries; and a general framework.

Abstract

This article presents one part of a wider study, performed at the Department of library and information science and book studies (LIS & BS) at the University of Ljubljana (UL). The study investigated the perceptions of user friendliness of information-retrieval systems (IRS) and the role of individual characteristics of users in these perceptions. Based on an expert study, a user study with 61 postgraduate students of the UL was performed. Three interfaces of e-journals were studied: Science Direct, Proquest Direct, and Ebsco Host. Questionnaires and observations were used for data collection. The users'perceptions of user friendliness and of importance of auxiliary functions were investigated. Also, the connections between these perceptions and the users'individual characteristics were identified. Three sets of individual characteristics were included: approaches to studying, thinking styles, and hemisphere leanings. In connection with the dimensions of individual characteristics, very different perceptions of user friendliness were expressed. Some dimensions of individual characteristics were also found to be connected to the users'academic areas. It is shown that participants from different academic areas have different requirements and perceptions of user friendliness. The results of the study are relevant for the design of the user interfaces of disciplinary IR systems. They also have implications for other areas, for example, user education and training.

Abstract

Domain visualization is one of the new research fronts resulted from the proliferation of information visualization, aiming to reveal the essence of a knowledge domain. Information visualization plays an integral role in modeling and representing intellectual structures associated with scientific disciplines. In this article, the domain of computer graphics is visualized based on author cocitation patterns derived from an 18-year span of the prestigious IEEE Computer Graphics and Applications (1982-1999). This domain visualization utilizes a series of visualization and animation techniques, including author cocitation maps, citation time lines, animation of a highdimensional specialty space, and institutional profiles. This approach not only augments traditional domain analysis and the understanding of scientific disciplines, but also produces a persistent and shared knowledge space for researchers to keep track the development of knowledge more effectively. The results of the domain visualization are discussed and triangulated in a broader context of the computer graphics field

Abstract

Over the last couple of years, there has been a surge of activity in the library automation arena directed toward improved user interfaces. As Breeding looks at the events and activities that have transpired over the last year or so, Breeding sees an incredible amount of progress in creating interfaces that help librarians compete better in an ever more crowded landscape of information providers. It's strategically important for libraries to have technologies in place that will optimize delivery of content and services in the context of today's Web. Breeding believes that failure to make progress in this area can foster a creep of irrelevancy as potential users increasingly rely on information resources provided by entities other than libraries.

Abstract

Users interact with museum application interfaces for many reasons. There are various types of users, who want to perform various tasks, in various contexts, that can access the same Web site. Thus, it is important to have user interfaces able to adapt to these different user requirements to facilitate the accomplishment of the desired goals. Most current interfaces to museum information do not take into account this variety of types of users, thus providing interfaces that some users find confusing to achieve their goals. In this article we discuss the various possible levels of support that can be given to different users during navigation of museum information. In particular, we focus our attention on how to obtain adaptable and adaptive interfaces using the web site for the Marble Museum, which we have designed and developed, as a source of examples for our discussion of possible solutions

Abstract

While most research in the area of human-information behavior has focused an a single dimension-either the psychological or the social-this case study demonstrated the importance of a multidimensional approach. The Cognitive Work Analysis framework guided this field study of one event of collaborative information retrieval (CIR) carried out by design engineers at Microsoft, including observations and interviews. Various dimensions explained the motives for this CIR event and the challenges the participants encountered: the cognitive dimension, the specific task and decision, the organization of the teamwork, and the organizational culture. Even though it is difficult at times to separate one dimension from another, and all are interdependent, the analysis uncovered several reasons for design engineers to engage in CIR, such as when they are new to the organization or the team, when the information lends itself to various interpretations, or when most of the needed information is not documented. Similar multidimensional studies will enhance our understanding of human-information behavior.

Abstract

To explore issues of user interface design and experience, including culturally preferred design elements, a study was conducted analyzing sites in Germany, Japan, and the United States (30 municipal sites in each country). Design elements considered are use of symbols and graphics, color preferences, site features (links, maps, search functions, and page layout), language, and content. Significant modal differences were found in each of the listed categories. Outcomes from the study are used to discuss future research directions in the areas of experience design and localization.

Abstract

This paper reports the results of a study that examined Arabic-speaking children's interaction with the International Children's Digital Library (ICDL). Assessment of the ICDL to Arabic-speaking children as a culturally diverse group was grounded in "representations" and "meaning" rather than in internationalization and localization. The utility of the ICDL navigation controls was judged based on the extent it supported children's navigation. Most of the ICDL representations and their meanings were found to be highly appropriate for older children but inappropriate for younger ones. The design of the ICDL navigation controls was supportive of children's navigation. Recommendations for assessing the cross-cultural usability of the ICDL are made and suggestions for system design improvements are provided.

Abstract

User-centered design (UCD) emerged a couple of decades ago because people had difficulties in using systems. It is founded on the principle that users need to be involved in the design and development process for systems to be truly usable-efficient, effective, and satisfying. This entry provides an account of the background-the technological and social forces that affect the evolution of systems development, an explanation of the theoretical foundation on which UCD is build, and a description of a typical UCD process.

Abstract

The recent explosion of the Internet and the WWW has made digital libraries popular. Easy access to a digital library is provided by commercially available Web browsers, which provide a user-friendly interface. To retrieve documents of interest, the user is provided with a search interface that may only consist of one input field and one push button. Most users type in a single keyword, click the button, and hope for the best. The result of a query using this kind of search interface can consist of a large unordered set of documents, or a ranked list of documents based on the freuqency of the keywords. Both lists can contain articles unrelated to the user's inquiry unless a sophisticated search was performed and the user knows exactly what to look for. More sophisticated algorithms for ranking the search results according to how well they meet the users needs as expressed in the search input may help. However, what is desperately needed are software tools that can analyze the search result and manipulate large hierarchies of data graphically. In this article we describe the design of a language-independent document classification systems being developed to help users of the Florida Center for Library Automation analyze search query results. Easy access through the Web is provided, as well as a graphical user interface to display the classification results. We also describe the use of this system to retrieve and analyze sets of documents from public Web sites

Abstract

Digital libraries need to facilitate the use of digital information in a variety of settings. One approach to making information useful is to enable its application to situations unanticipated by the original author. Walden's Path is designed to enable authors to collect, organize, and annotate information from on-line collections for presentaion to their readers. Experiences with the use of Walden's Paths in high-school classrooms have identified 4 needs/issues: (1) better support for the gradual authoring of paths by teachers, (2) support for student authoring of paths including the ability for students to collaborate on paths, (3) more obvious distinction between content of the original source materials and that added by the path author, and (4) support for maintaining paths over an evolving set of source documents. These observed needs have driven the development of new versions of Walden's Paths. Additionally, the experiences with path authoring have led to a conceptualization of metadocuments, documents whose components include complete documents, as a general domain where issues of collaboration, intellectual property, and maintenance are decidedly different form traditional document publication
