Abstract
In this study of various evaluation-instruments, subjects fulfilled several tasks on two different operating systems and answered several questionnaires, among them AttrakDiff™ and ISONORM 9241/10, and objective measures were taken. A correlation between the "hedonic quality - identity-scale of the AttrakDiff™ and the ISONORM 9241/10 was found. As the ISONORM 9241/10 measures usability as described in ISO 9241-10 and not hedonic quality, the hedonic quality seems to have an influence on the tester ratings of usability. This is supported by the finding, that the hedonic quality does not correlate with the objective measures and therefore docs not have any effective influence on the efficiency component of usability. © IFIP International Federation for Information Processing 2005.
