    Abstract
    Für Webseiten ist, wie für alle interaktiven Anwendungen vom einfachen Automaten bis zur komplexen Software, die Benutzerfreundlichkeit von zentraler Bedeutung. Allerdings wird eine sinnvolle Benutzung von Informationsangeboten im World Wide Web häufig durch "cooles Design" unnötig erschwert, weil zentrale Punkte der Benutzerfreundlichkeit (Usability) vernachlässigt werden. Durch Usability Evaluation kann die Benutzerfreundlichkeit von Webseiten und damit auch die Akzeptanz bei den Benutzern verbessert werden. Ziel ist die Gestaltung von ansprechenden benutzerfreundlichen Webangeboten, die den Benutzern einen effektiven und effizienten Dialog ermöglichen. Das Buch bietet eine praxisorientierte Einführung in die Web Usability Evaluation und beschreibt die Anwendung ihrer verschiedenen Methoden.

    Abstract
    This book outlines the human side of the information seeking process, and focuses on the aspects of this process that can best be supported by the user interface. It describes the methods behind user interface design generally, and search interface design in particular, with an emphasis on how best to evaluate search interfaces. It discusses research results and current practices surrounding user interfaces for query specification, display of retrieval results, grouping retrieval results, navigation of information collections, query reformulation, search personalization, and the broader tasks of sensemaking and text analysis. Much of the discussion pertains to Web search engines, but the book also covers the special considerations surrounding search of other information collections.

    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. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

    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
    Dieses Buch beweist: Barrierefreiheit und attraktives Webdesign schließen sich nicht aus! Nach einer Beschreibung der Grundlagen (Behinderungen, mit denen Webdesigner bei ihren Anwendern rechnen müssen, technische Lösungen wie Braille-Zeile, rechtliche Vorgaben etc.) entwickeln die Autoren an einem konkreten Praxisprojekt, wie eine nicht barrierefreie Website barrierefrei gemacht wird. Hierbei beschreiben sie ausführlich die Analyse- und Konzeptionsphase, Design-Kriterien, die technische Umsetzung, Nutzer-Tests sowie die vor und nach dem Relaunch involvierten Prozesse. Ein Kapitel zur barrierefreien Gestaltung einer CMS-basierten Website (Joomla!, TYPO3) rundet das Buch ab.

    Rez. in: Information - Wissenschaft und Praxis 58(2007) H.5, S.318 (W. Schweibenz): "Der Titel des Buches verspricht, dass es möglich sei, Web-Sites nicht nur barrierefrei, sondern auch attraktiv zu gestalten. Dieses Versprechen lösen Angie Radtke und Michael Charlier mit einer DemoWeb-Site für die fiktive Gemeinde BadSeendorf (Internet, URL http://www.badseendorf.de) ein. Dort werden einander zwei Versionen gegenübergestellt, wobei der Ausgangspunkt ein barrierebehaftetes Design ist, das durch eine barrierearme Version ersetzt wird. Diese beiden Beispiele wären für sich genommen bereits sehr hilfreich bei der Auseinandersetzung mit dem Thema Barrierefreiheit. In Kombination mit dem zugehörigen Buch haben Radtke und Charlier eine umfassende Einführung geschaffen, die sowohl für die eigenständige Einarbeitung in die Thematik als auch für die Verwendung in der Lehre sehr geeignet ist. In einem knappen theoretisch ausgerichteten Grundlagenteil werden Fragen behandelt wie beispielsweise was Barrierefreiheit ist und wem sie nützt, warum Zugänglichkeit und ansprechendes Design kein Widerspruch sind und welche gesetzlichen Vorgaben gelten. Im Mittelpunkt des umfangreichen Praxisteils steht die genannte Web-Site der fiktiven Gemeinde Bad-Seendorf. Ausgehend von dem barrierebehafteten Design werden an konkreten Beispielen die Probleme bestimmter Nutzergruppen analysiert, zu denen neben den üblicherweise dargestellten Betroffenen auch die Altersgruppe 50plus zählt, die häufig vernachlässigt wird. Weiterhin wird in einzelnen Kapiteln eine Analyse von Barrieren durchgeführt, sowie Maßnahmen zur gezielten Vermeidung von Zugangsblockaden und Zugangserschwernissen aufgezeigt, wobei auch auf multimediale Inhalte und Sonderfälle wie PDF, Flash, und Videos in Deutscher Gebärdensprache eingegangen wird. Eine kurze Beschreibung des Einsatzes von Content-Management-Systemen für barrierefreie Web-Angebote legt den Schwerpunkt auf die Systeme Joomla! und TYPO3.
    Insgesamt zeichnet sich die Kombination von Buch und Web-Site durch einen hohen Praxisbezug aus. Die Texte sind leicht zu lesen, die Sprache ist einfach und verständlich. Zahlreiche farbliche und grafisch gestaltete Randnotizen enthalten Verweise und Erläuterungen und stellen Bezüge her, sowohl zu den Beispielen als auch zu den einzelnen Prüfpunkten der Barrierefreie Informationstechnik-Verordnung (BITV). In den Text integrierte Abbildungen sowie Hinweise auf Benutzungsprobleme für Menschen mit Behinderungen und Testmöglichkeiten machen die Problematik von Barrieren deutlich, auch für Leser, welche die Vorteile einer barrierearmen Gestaltung von Web-Sites verstehen wollen, ohne sich auf die Ebene des Quellcodes begeben zu müssen, wobei die Beispiele durchaus eine tiefergehende Auseinandersetzung mit der Programmierung erlauben."

    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

    Rez. in: Information - Wissenschaft und Praxis 56(2005) H.8, S.459 (W. Schweibenz): "Das Buch behandelt in sechs Kapiteln und einem umfangreichen Anhang die barrierefreie Zugänglichkeit von Web-Anwendungen. Es wurde von einem vierzehn Personen umfassenden Autorenteam geschrieben und kann inzwischen als eines der deutschsprachigen Standardwerke zu diesem Thema gelten. Die erste Auflage war nach ihrem Erscheinen im Oktober 2004 binnen weniger Wochen ausverkauft, bereits im Dezember 2004 wurde die zweite Auflage herausgebracht. Das erste Kapitel erläutert Grundlagen und Notwendigkeit der barrierefreien Informationstechnik. Dabei erhalten die Leser Einblick in die Schwierigkeiten, die sich für Menschen mit Behinderungen bei der Computerbenutzung ergeben und mit welchen Hilfsmitteln diese Probleme gelöst oder zumindest reduziert werden können. Weiterhin wird auch auf die gesetzlichen Vorgaben in der BRD und die Umsetzungsrichtlinien der Web Accessibility Initiative (WAI) eingegangen, wobei sich diese Ausführungen allgemein gehalten sind und nur den Bereich des Bundes behandeln; die rechtlichen Gegebenheiten auf Länderebene dagegen werden nicht dargestellt. Die folgenden Kapitel des Buches richten sich überwiegend an Leser mit technischen Interessen bzw. Kenntnissen und vermitteln eine praxisnahe Anleitung zur technischen Umsetzung von Barrierefreiheit, die sich an den inhaltlich orientierten Anforderungen der Barrierefreie Informationstechnik-Verordnung (BITV) orientiert. Behandelt werden Web-Standards wie (X)HTML und CSS, wobei ausführlich auf Fragen der Geräteunabhängigkeit und Validierung eingegangen wird, aber auch auf Anwendungen wie JavaScript und multimediale Anwendungen wie Macromedia Flash oder druckähnliche Ausgabeformate wie PDF (Portable Document Format), das entgegen verbreiteter Annahmen nicht per se barrierefrei ist. Ein eigenes Kapitel zur barrierefreien Gestaltung von grafischen Programmoberflächen gibt Einblick in die IBM-Leitlinien zur Barrierefreiheit. Der Praxisteil mit Tipps zum Testen von Barrierefreiheit und zur Projektdurchführung rundet das Buch ab. Der Anhang enthält den Text der BITV sowie ein Glossar technischer Begriffe. Die CD-ROM - selbstverständlich barrierefrei gestaltet - zeigt zahlreiche Medien-Clips sowie Beispiele, Anleitungen und Demonstrationen. Für technisch orientierte Leser bietet das Buch eine umfassende Einführung in die wichtigsten Fragen zur Barrierefreiheit im Web. Dies reicht von der Fragestellung,was unter Barrierefreiheit zu verstehen ist, über rechtliche Fragen sowie Richtlinien bis zur praktischen Umsetzung. Für die Zielgruppe, die mit Web-Entwickler, Web-Designer, Web-Programmierern und Online-Redakteuren angegeben wird, bietet das Buch eine vollständige und gut nachvollziehbare Handreichung, die sich durch ihren hohen Praxisbezug auszeichnet."
