Abstract

Unsere Medienwelt ist vom Nebeneinander verschiedener Ausgabeformen derselben Inhalte geprägt. Es herrscht jedoch Mangel an Untersuchungen, welche die "usability" von Printmedien mit der von Online-Medien direkt vergleichen. Im Rahmen eines Projektseminars am Institut fürBibliothekswissenschaft der Humboldt- Universität Berlin wurde die Usability von gedruckten und von Online-Informationsmitteln anhand heuristischer Kriterien verglichen. Als Benutzungsaspekte bündelndes und messbares Kriterium wurde der Zeitbedarf zur Beantwortung einfacher Testaufgaben ermittelt, die sowohl anhand der Print- als auch anhand der Online-Version je eines Versandhauskatalogs und eines Vorlesungsverzeichnisses zu beantworten waren. Die Prognosen sowie die Ergebnisse dreier Gruppen (Bibliothekswissenschaft-Studenten, Informatik-Studenten und Laien) wurden verglichen. Der Zeitbedarf für die Nutzung der Printmedien wurde von den Bibliothekswissenschaft- und Informatik-Studenten zu hoch prognostiziert, für Online-Medien zu niedrig. Der tatsächliche Zeitbedarf bewegte sich in ähnlicher Größenordnung bei beiden Versionen des Vorlesungsverzeichnisses. Bei der Nutzung des Versandhauskatalogs hingegen war der Zeitbedarf online doppelt so hoch wie beim Printmedium. Zusätzlich war bei Nutzung der Online-Version die Hälfte der Antworten falsch. Der Grad an subjektiver Unsicherheit über die Richtigkeit der Antworten wurde, damit übereinstimmend, bei der Online-Version deutlich höher eingeschätzt als beim Printmedium. Die Testergebnisse derdrei Gruppen unterschieden sich beim Versandhauskatalog nur wenig. Die Ergebnisse werden als Hinweis auf schlechten Entwicklungsstand der Usability von Online-Medien gedeutet. Die Usabilityvon konventionellen Medien scheint von "computernahen" Nutzern unterschätzt zu werden. Bei der Nutzung von Online-Medien wird in derLiteratur oft hohe subjektive Unsicherheit über die Angemessenheit oder Richtigkeit der Suchresultate berichtet, die hier bestätigt wird und zugleich mit einem hohen Anteil objektiv falscher Antworten korrespondiert. Es wird dafür plädiert in die Usability-Forschung konventionelle Medien einzubeziehen und stärker interdisziplinär vorzugehen.
