Abstract

The two facets of "going visual" are usually referred to as visual query systems, for query formulation, and information visualization, for result display. Visual Query Systems (VQSs) are defined as systems for querying databases that use a visual representation to depict the domain of interest and express related requests. VQSs provide both a language to express the queries in a visual format and a variety of functionalities to facilitate user-system interaction. As such, they are oriented toward a wide spectrum of users, especially novices who have limited computer expertise and generally ignore the inner structure of the accessed database. Information visualization, an increasingly important subdiscipline within the field of Human-Computer Interaction (HCI), focuses an visual mechanisms designed to communicate clearly to the user the structure of information and improve an the cost of accessing large data repositories. In printed form, information visualization has included the display of numerical data (e.g., bar charts, plot charts, pie charts), combinatorial relations (e.g., drawings of graphs), and geographic data (e.g., encoded maps). In addition to these "static" displays, computer-based systems, such as the Information Visualizer and Dynamic Queries, have coupled powerful visualization techniques (e.g., 3D, animation) with near real-time interactivity (i.e., the ability of the system to respond quickly to the user's direct manipulation commands). Information visualization is tightly combined with querying capabilities in some recent database-centered approaches. More opportunities for information visualization in a database environment may be found today in data mining and data warehousing applications, which typically access large data repositories. The enormous quantity of information sources an the World-Wide Web (WWW) available to users with diverse capabilities also calls for visualization techniques. In this article, we survey the main features and main proposals for visual query systems and touch upon the visualization of results mainly discussing traditional visualization forms. A discussion of modern database visualization techniques may be found elsewhere. Many related articles by Daniel Keim are available at http://www. informatik.uni-halle.de/dbs/publications.html.

Abstract

The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry.

Abstract

Purpose - The purpose of this paper is to investigate the usability of a web-based OPAC (WebPAC) user interface at the International Islamic University Malaysia (IIUM). It also looks at the applicability of heuristic evaluation in designing a user-centered WebPAC interface. Design/methodology/approach - Based on Nielsen's ten usability heuristic principles, the study focuses on three heuristics only, i.e. aesthetic and minimalist design, match between interface and the real world, and visibility of interface status. Findings - Results of the study found that the WebPAC interface conforms to at least 70 percent usability properties prescribed. Usability problems violated in the interface were identified. Practical implications - The study suggests that heuristic evaluation is applicable in libraries to asses the usability of user interface for online catalogs. Originality/value - Heuristic evaluation could assist libraries in designing user-centered interface for online catalogs.

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

Almost all Web searches are carried out while the user is sitting at a conventional desktop computer connected to the Internet. Although online, handheld, mobile search offers new possibilities, the fast-paced, focused style of interaction may not be appropriate for all user search needs. The authors explore an alternative, relaxed style for Web searching that asynchronously combines an offline handheld computer and an online desktop personal computer. They discuss the role and utility of such an approach, present a tool to meet these user needs, and discuss its relation to other systems.

Abstract

User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

Abstract

An evidence-based practice approach to search interface design is proposed, with the goal of designing interfaces that adequately support search strategy formulation and reformulation. Relevant findings from studies of information professionals' searching behaviors, end users' searching of bibliographic databases, and search behaviors on the Web are highlighted. Three brief examples are presented to illustrate the ways in which findings from such studies can be used to make decisions about the design of search interfaces. If academic research can be effectively connected with design practice, we can discover which design practices truly are best practices and incorporate them into future search interfaces.

Abstract

The advent of the heterogeneous digital library provides the opportunity and establishes the need for the design of new user interfaces. As a single portal to a wide array of information sources, the heterogeneous digital library requires that a variety of cataloging schemas, subject domains, document genres, and institutional biases be accomodated. SenseMaker is a user-centered interface for information exploration in a heterogeneous digital library. It unifies citations and articles from heterogeneous sources by presenting them in a common schema with affordances for quick comparisons of properties. At the same time, SenseMaker users can recover a degree of context by iteratively organizing citations and articles into higher-level bundles based on either metadata or content. Furthermore, SenseMaker enables users to move fluidly from browsing to searching by introducing structure-based searching and structure-based filtering. This paper outlines the SenseMaker interface design and details some of our experimental findings surrounding its use

Abstract

Die meisten Web-Auftritte der Hosts waren bisher für den Retrieval-Laien gedacht. Im Hintergrund steht dabei das Ziel: mehr Nutzung durch einfacheres Retrieval. Dieser Ansatz steht aber im Konflikt mit der wachsenden Datenmenge und Dokumentgröße, die eigentlich ein immer ausgefeilteres Retrieval verlangen. Häufig wird von Information Professionals die Kritik geäußert, dass die Webanwendungen einen Verlust an Relevanz bringen. Wie weit der Nutzer tatsächlich einen Kompromiss zwischen Relevanz und Vollständigkeit eingehen muss, soll in diesem Beitrag anhand verschiedener Host-Rechner quantifiziert werden

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

Web Usability konnte sich als Forschungsbereich zunächst nur in größeren Firmen der Internet-Branche wie z. B. Icon Medialab etablieren. Mit zunehmender Konkurrenz und ersten Pleiten im E-Commerce entsteht die Einsicht oder bittere Erfahrung, dass bunte, multimediale Internetpräsenz nicht alles ist: Die Nutzungsqualität von Websites tritt in den Vordergrund und damit ein neuer Arbeitsmarkt für Informationsarchitekten und HCI- bzw. Usability-Spezialisten. Suchmaschinen sind eine besondere Kategorie von Website. Sie entstehen in einem Spannungsfeld zweier unterschiedlicher Interessen: Mit kommerziellen Websites teilen sie den Wettbewerb um Kunden und die Art der Kunden: den ungeduldigen gelegentlichen Anwender. Mit der akademischen Welt teilen sie das forschende Bemühen um die Optimierung von Features und Funktionen und die déformation professionelle der Eingeweihten. Am Beispiel zweier Untersuchungen wird deutlich, wie es der richtige 'Methodenmix' ermöglicht, bei der Evaluation der Nutzungsqualität von Suchmaschinen ganz unterschiedlicher Art (a) diesen Interessenkonflikt bewusst zu machen, (b) Empathie für die Nöte der Kunden zu entwickeln und c) allgemeingültige Kriterien zur Entwicklung gebrauchstauglicher Suchmaschinen aufzustellen. Beide Untersuchungen fanden im Rahmen des Projekts Jorschung und Forschungsumgebung für Web Usability« unter Mitwirkung von Studierenden am Fachbereich Bibliothek und Information der FH Hamburg statt

Abstract

This study explores an image-based retrieval interface for drug information, focusing on usability for a specific population - seniors. Qualitative, task-based interviews examined participants' health information behaviors and documented search strategies using an existing database (www.drugs.com) and a new prototype that uses similarity-based clustering of pill images for retrieval. Twelve participants (aged 65 and older), reflecting a diversity of backgrounds and experience with Web-based resources, located pill information using the interfaces and discussed navigational and other search preferences. Findings point to design features (e.g., image enlargement) that meet seniors' needs in the context of other health-related information-seeking strategies (e.g., contacting pharmacists).

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.
