We report from three usability evaluations of health information systems that illustrate the value of seeing usability as a context dependent property of a product. We show how the definition of usability in ISO 9241-11 can be used as a guiding principle in the evaluation, specification and design of such systems. The contextual view on usability is particularly important for health information...

Web GIS applications can be found in many domains. The quality of the interfaces of applications determines not only the usability of such applications, but the possibilities offered to their users. This work investigates aspects of interface quality for Web GIS applications. The approach adopts an inspection evaluation based on ISO 9241. Preliminary results show the effectiveness of such an ap...

Der vorliegende Beitrag beschreibt eine Vorgehensweise zur modellbasierten und nutzerzentrierten Entwicklung von Mensch-MaschineSchnittstellen. In aufeinanderfolgenden Phasen der Systementwicklung werden unterschiedliche Modelle angelegt bzw. weiterentwickelt, die jeweils als Ausgangsbasis für die nächste Phase benutzt werden. Die Vorgehensweise stützt sich auf die ISO 9241-210 (Human-centred d...

The ISO 9241 Part 9 standard [2] pointing task is used to evaluate passive haptic feedback in target selection in a virtual environment (VE). Participants performed a tapping task using a tracked stylus in a CAVE both with, and without passive haptic feedback provided by a plastic panel co-located with the targets. Pointing throughput (but not speed nor accuracy alone) was significantly higher ...
