Our publication about „The XAOS Metric – Understanding Visual Complexity as measure of usability“ held at the 6th Symposium (USAB 2010) of the Workgroup HCI&UE of the Austrian Computer Society in Carinthia (Southern Austria). The slides are already available here.
Abstract:
The visual complexity of an interface is a crucial factor for usability, since it influences the cognitive load and forms expectations about the subjacent software or system. In this paper we propose a novel method that uses entropy, structure and functions, to calculate the visual complexity of a website. Our method is evaluated against a well known approach of using the file size of color jpeg images for determining visual complexity. Both methods were applied on a dataset consisting of images of 30 different websites. These websites were also evaluated with a web survey. We found a strong correlation for both methods on subjective ratings of visual complexity and structure. This suggests both methods to be reliable for determination of visual complexity.

Das Lehrbuch Lehren und Lernen mit Technologien wird am 1.2.2011 auf der Learntec online freigeschalten. Nachdem nicht alle Interessierten daran teilnehmen können, wiewohl es uns sehr freuen würde, organisieren wir einen Online-Flashmob ab 14.45 Uhr. Einfach mitmachen, wir freuen uns darauf :-).
