Although handheld computers are increasingly used in professional areas, an instrument for evaluating their applicability in different cases and scopes does not yet exist. There is an urgent need for standardised evaluation methods comprising handheld specific questions like mobility, different hardware (CE, Palm, Psion), different possibilities for data capture (keyboard versus pen), different...

Interaction Objects, Computer Systems, Presentation, Standardisation, System Development, User Interface Design, Visual Performance. Terminal recommendations and rules from most standards generally include references to various interaction objects belonging to different target environments. Since these references are not made explicit, the standard user is responsible to make a pattern matching...

A previous paper compared the 110 guidelines in ISO CD 9241-151 with the 187 guidelines produced by the U.S. Department of Health and Human Services (HHS) and found that 76% of the HHS guidelines and 54% of the ISO guidelines were unique. New versions of both the original 2004 documents were issued in 2006, but 71% of the HHS guidelines and 46% of the ISO guidelines are still unique. Neither se...

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...

Fifteen participants completed a study comparing video game controllers for point-select tasks. We used a Fitts’ law task, as per ISO 9241-9, using the Nintendo Wii Remote for infrared pointing, the Nintendo Classic Controller for analogue stick pointing, and a standard mouse as a baseline condition. The mouse had the highest throughput at 3.78 bps. Both game controllers performed poorly by com...

We present two studies to comparatively evaluate the performance of gesture-based 2D and 3D pointing tasks. In both of them, a Wiimote controller and a standard mouse were used by six participants. For the 3D experiments we introduce a configuration analogous to the ISO 9241-9 standard methodology. We examine the pointing devices’ conformance to Fitts’ law, and we measure some extra parameters ...

A lot of the company's business activities failed due to not adapting user needs and technological developments. Previous studies show that there is no way implement UX guidelines explain specific for e-commerce systems. Therefore, we need a implementing websites. We used usability parameters in ISO 9241-11, namely effectiveness, efficiency, satisfaction, measure system's then conduct an interv...
