Abstract

Der Begriff "User Interface Tuning" bezeichnet verschiedene Maßnahmen und Methoden zur Gestaltung und Optimierung von Benutzungsschnittstellen. Ziel ist es, den Benutzer oder Endanwender in den Mittelpunkt aller Aktivitäten des Gestaltungsprozesses zu rücken. Dieses Buch gibt einen Einblick in die Methoden der benutzerzentrierten Gestaltung und beschreibt, wie sich solche Methoden in einen iterativen Gestaltungsprozess einbinden lassen. Anhand einer Fülle von Praxisbeispielen vermittelt das Buch, wie benutzerzentrierte Gestaltung in realen Entwicklungsprojekten umgesetzt werden kann und zum Gewinn für alle Beteiligten wird. Die Praxisbeispiele umfassen Anwendungen aus den Gebieten "Business und Industrie", "Business-to-Consumer" und "Consumer Products und Inclusive Design". Das Buch richtet sich an Produktmanager, Designer, Produktentwickler, Ergonomen und Psychologen sowie jeden Leser, der sich dafür interessiert, wie Produkte menschlicher und letztendlich erfolgreicher gestaltet werden können. Die Herausgeber des Buches sind bei der User Interface Design GmbH tätig und beraten seit mehr als 15 Jahren industrielle Unternehmen bei der benutzerzentrierten Gestaltung von interaktiven Systemen und Produkten.

Footnote

In den nachfolgenden Teilen "Business und Industrie", "Business to Consumer" und "Consumer" werden zahlreiche Anwendungsfälle mit ihren jeweiligen Besonderheiten beschrieben. Vermutlich wird sich nicht jeder Leser des Buchs gleichermaßen für alle in den hinteren Buchteilen beschriebenen Beispiele interessieren. Andererseits aber habe ich zum Beispiel durch das zwölfte Kapitel "Schweißen mit 60 Parametern ist ein echtes Handwerk" von Heinz Hackl, Michael Burmester und Andreas Beu gelernt, mit welchen hohen Anforderungen an die Gestaltung eines Interface zur Bedienung einer digitalen Schweißmaschine sich die Entwickler des Gerätes konfrontiert sehen. obwohl zunächst gar nicht in dem Maße erwartet, greifen natürlich auch hier die im ersten Buchteil behandelten Prinzipien des benutzerzentrierten Gestaltens, der detaillierten Anforderungsanalyse und der systematischen Evaluation, wie man sie eher von Interfaces für Software-Systeme oder Websites kennt. In seiner Gesamtheit vermittelt das Buch von Joachim Machate und Michael Burmester fundiertes Grundlagenwissen rund um die nutzerzentrierte Gestaltung von Interfaces, das mit Hilfe vieler Anwendungsbeispiele demonstriert und vertieft wird. Es richtet sich jedoch nicht nur an Einsteiger in das Gebiet; auch als Leser, der bereits mit Fragen der Ergonomie und Usability von Geräte- und Computeroberflächen etwas vertraut ist, wird man die Beiträge mit Gewinn lesen."

Abstract

Describes a WWW based system which allows users to view, search and post geographically indexed information of the Earth. 2 geographic browsers have been developed: a 2D map browser capable of continuous scroll and zoom of an arbitrarily large sheet and a 3D flight-simulator browser capable of continuous flight around the Earth. On the server side, a geographical and geometrical server has been developed which contains large databases of images, elevations, lines, points and polygons stored in tiles structured into hierarchical pyramids or quadtrees. A metadata server has also been developed which contains URL pointers and geographical coordinates of various WWW documents, geographical information and geometrical models

1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

Abstract

Wissenschaftliche Fachportale bieten Nutzern in der Regel ein umfangreiches Angebot an verschiedenen Informationen und Dienstleistungen. Die Organisation dieser Angebotsvielfalt lässt sich jedoch nur schwer oder gar nicht mit softwareergonomischen Richtlinien bezüglich Navigations- und Menüstrukturen vereinen. Nutzern wird zudem oft eine feste inhaltliche Sicht auf die enthaltenen Informationsangebote präsentiert, von der angenommen wird, dass sie all ihre Informationsbedürfnisse befriedigt. Der folgende Beitrag zeigt, wie ein Referenzmodell für die Informationsarchitektur in Fachportalen die Informationsangebote als dynamisches Browsing in Form eines Produktkataloges integriert und verschiedene Sichten auf die Angebote ermöglicht. Eine abschließende Evaluation des Konzepts zeigt, dass die Nutzer mithilfe des Produktkataloges die Informationsangebote der Website einfacher finden können als mit einem herkömmlichen statischen Menü.

Abstract

Zunächst werden neun unterschiedliche Umgebungen bzw. Kontexte von Webseiten eingeführt. Jeder Kontext soll die Orientierung und Navigation bezüglich eines bestimmten Aspekts ermöglichen. Der Linkkontext einer bestimmten Webseite besteht beispielsweise aus den Webseiten und Links, die von dieser Seite aus über eine definierte Anzahl von Links erreichbar sind. Die Darstellung dieses Kontexts soll die Orientierung und Navigation unter dem Aspekt der Links, des assoziativen Umfelds dieser Seite verbessern. Die Aspekte, unter denen die Kontexte die WWW-Benutzung verbessern sollen, betreffen entweder die Struktur, die Benutzung oder den Inhalt der Webseiten. Damit die Kontexte die gewünschte Wirkung erzielen können, muß ein Benutzer sie wahrnehmen können. Dazu wird eine neue Visualisierungstechnik vorgestellt: das Verfahren der BrowsingIcons und BrowsingGraphs. Während der Navigation im WWW entstehen wiedererkennbare, visuelle Zeichen für einzelne Sessions (Benutzersitzungen). Man kann schnell erkennen, wo man sich gerade innerhalb des jeweiligen Kontexts befindet (Orientierung). Ferner kann man direkt über mehrere Links hinweg einzelne Webseiten ansteuern (Navigation). Frühere Sitzungen können an der charakteristischen Form der BrowsingIcons erkannt werden. Die Metapher biologischer Kulturen wird auf BrowsingGraphs übertragen. Durch "Impfen" von "Nährlösungen" können Suchanfragen intuitiv gestellt werden. Die Ergebnisse kann man später "ernten"

Abstract

This paper discusses constraints in knowledge organisation for information retrieval introduced by the difficulty of separating logical views of data, information, concepts and their relationships, from the physical means by which we seek to implement retrieval systems. A parallel is drawn between the move from enumerated to faceted classification and the emergence of relational database management systems to replace those adopting a hierarchical structure. This parallel suggests a convergence of ideas which have been, to a large extent, developed independently. The role of post-coordinated retrieval systems and thesauri is then examined before an interface design (HIBROWSE - a High resolution Interface for BROWsing and SEarching databases), is described which brings together the principles of faceted classification and increases the bandwidth of interaction through view-based searching.

Abstract

Brajnik et alia describe their view of an effective retrieval interface, one which coaches the searcher using stored knowledge not only of database structure, but of strategic situations which are likely to occur, such as repeating failed tactics in a low return search, or failing to try relevance feedback techniques. The emphasis is on the system suggesting search strategy improvements by relating them to an analysis of work entered so far and selecting and ranking those found relevant. FIRE is an interface utilizing these techniques. It allows the user to assign documents to useful, topical and trash folders, maintains thesauri files automatically searchable on query terms, and it builds, using user entries and a rule system, a picture of the retrieval situation from which it generates suggestions. Six participants used FIRE in INSPEC20K database searches, two for their own information needs and four needs provided by the authors. Satisfaction was measured in a structured post search interview, behavior by log analysis, and performance by recall and precision in the canned searches. Participants found the suggestions helpful, but insisted they would have taken those approaches without such assistance. Users took the suggestions offered and preferred those demanding the least effort.

Abstract

Yu and Roh investigate the effects of providing a simple menu, a global and local navigation menu, and a pull-down menu on searching and browsing speed, as well as the user's perception of the appeal of each menu form and the degree of disorientation it might cause. The site was a shopping center with items and prices that could be approached by way of a simple menu with a hierarchal structure, a menu which retained global links across the top of the screen, with local links in a frame to the left, or a pull down menu design. Each of 21 student subjects was given ten searching and five browsing tasks assigned in three treatments, and responded to a post exercise questionnaire using a five point Likert scale on attitude toward the menus. Time was measured from the subjects' indication of starting until the price was provided, and the procedure repeated three times over a three-week interval with treatment switching. A repeated measure ANOVA showed a significant difference among the designs on search speed with the pull-down menu leading the other two. In browsing speed pull-down and global/local were not significantly different but both bettered the simple menu. Attitude and disorientation showed no significant differences.

Abstract

Unter computervermittelter Kommunikation (CvK) bzw. Computer-Mediated-Communication (CMC) versteht man soziale (d.h. im weitesten Sinne zwischenmenschliche) Kommunikation, die über Computernetzwerke vermittelt wird. Damit Botschaften computervermittelt übertragen werden können, müssen sie digital vorliegen (d.h. in einer Binärcodierung: 0-1), weshalb man computervermittelte Kommunikation auch als digitale Kommunikation bezeichnen kann. Weitere Synonyme sind Online-Kommunikation, Netzkommunikation und Cyberkommunikation. Die computervermittelte Kommunikation steht neben anderen Formen der technisch vermittelten Kommunikation (z.B. Telefon-Kommunikation, Telefax-Kommunikation, Radio-Kommunikation, Fernseh-Kommunikation). Oftmals wird sie mit der technisch unvermittelten Face-to-Face-Kommunikation (FtF, F2F) kontrastiert. Im Unterschied zur technisch vermittelten Telekommunikation und Massenkommunikation, bei der die Beteiligten räumlich getrennt sind, ist es für die Face-to-FaceKommunikation notwendig, dass die Kommunizierenden alle zur selben Zeit am gleichen Ort zusammenkommen (Kopräsenz), um sich verbal und nonverbal auszutauschen. Diese Restriktion der Face-to-Face-Kommunikation verhindert viele Kommunikationsprozesse, weil bestimmte Personen beispielsweise keine Gelegenheit zur Kopräsenz haben, weil in der Kopräsenz immer nur einzelne das Wort ergreifen können und weil diverse Themen wegen sozialer Normen und Tabus im direkten Austausch ausgespart bleiben. Wenn zwischenmenschliche Kommunikation computervermittelt abläuft, heißt dies nicht, dass Faceto-Face-Botschaften einfach über einen anderen (nämlich computertechnischen) Kanal übertragen werden. Vielmehr werden durch CvK neue Kommunikationssituationen geschaffen, in denen teilweise andere Personen miteinander in Kontakt treten und/oder andere Themen in anderer Weise behandelt werden. So eröffnet sich beispielsweise Menschen mit Suizidgedanken in einem entsprechenden Online-Forum die Möglichkeit, unzensiert und anonym über ihre Befindlichkeit zu schreiben. In diesem Szenario wird Face-to-Face-Kommunikation nicht durch Netzkommunikation verdrängt, sondern das bisherige Schweigen der Betroffenen überwunden. Unter welchen Bedingungen die neuen Online-Kommunikationsszenarien für welche Individuen und Gruppen hilfreich oder schädlich sind, ist eine zweite Frage. So mag ein Suizidforum durch den unzensierten emotionalen Austausch mit Gleichgesinnten das Gefühl von Einsamkeit reduzieren und somit die Befindlichkeit bessern, es könnte aber andererseits durch den Austausch über Suizidmethoden die Suizidabsicht verstärken. Entsprechende Fragen sind nur durch theoriegeleitete empirische Studien zu klären. Generell gilt, dass soziale Kommunikation außerhalb wie innerhalb des Netzes nicht auf bloße Informationsübermittlung zwischen Sender und Empfänger zu reduzieren ist, sondern eine wechselseitige Verständigung impliziert.
