[publication] Usability metrics of time and stress – Biological enhanced performance test of a university wide learning management system

Im Rahmen der USAB 2008 mit dem Thema „HCI & Usability for Education and Work“ haben wir einen Beitrag zu „Usability metrics of time and stress – Biological enhanced performance test of a university wide learning management system“ erstellt.
Abstract:

This paper describes the modification and outcome of a performance test applied to a university wide learning management system under realistic conditions to identify usability problems and to compare measures such as success rate, task time and user satisfaction with requirements. Two user groups with 20 test users each took part in this study. During the whole test psychophysiological parameters of the test persons were monitored and recorded, in order to find event related stress symptoms. Modifications of the original test allowed a faster analysis of relevant quantitative metrics and the collection of qualitative information.

[publication] Security Privacy Challenges in E-Learning 2.0

Zusammen mit Edgar Weippl von der TU Wien habe ich einen Beitrag über Security und E-Learning 2.0 für die heurige E-Learn Conference erstellt.
Abstract:

E-Learning 2.0 uses Web 2.0 tools for e-learning. New services on the Internet can be
swiftly integrated into existing applications; students can create MashUps, for instance, using a
variety of services on the Internet. The main risk comes from the fact that students and teachers are
not entirely aware that their institution does not control these services. The servers are located in a
variety of countries, thus privacy laws also differ. In addition, as most Web applications are built as
three-tier architectures, typical security weaknesses exist, such as invalid input, a lack of server-
side checks, and excessive privileges
