Abstract

The Internet gives access for blind and visually impaired users to previously unobtainable information via Braille or speech synthesis interpretation. This paper looks at how three search engines, AltaVista, Yahoo! and Infoseek presented their information to a small group of visually impaired and blind users and how accessible individual Internet pages are. Two participants had varying levels of partial sight and two Subjects were blind and solely reliant on speech synthesis output. Subjects were asked for feedback on interface design at various stages of their search and any problems they encountered were noted. The barriers to access that were found appear to come about by lack of knowledge and thought by the page designers themselves. An accessible page does not have to be dull. By adhering to simple guidelines, visually impaired users would be able to access information more effectively than would otherwise be possible. Visually disabled people would also have the same opportunity to access knowledge as their sighted colleagues.

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.
