The success of web-based applications depends on how well it is perceive by the end-users. The various web accessibility guidelines have promoted to help improve accessing, understanding the content of web pages. Designing for the total User Experience (UX) is an evolving discipline of the World Wide Web mainstream that focuses on how the end users will work to achieve their target goals. To sa...

Aiming at a user-oriented approach in software evaluation on the basis of ISO 9241 Part 10, we present a questionnaire (IsoMetrics) which collects usability data for summative and formative evaluation, and document its construction. The summative version of IsoMetrics shows a high reliability of its subscales and gathers valid information about differences in the usability of different software...

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...

Eine der wichtigsten Methoden zur Evaluation von Software-Usability ist der Einsatz von Benutzerfragebögen. Diese Studie widmet sich dem Vergleich der zwei im deutschsprachigen Raum verbreitetesten Fragebögen, Isonorm und Isometrics, die beide dasselbe Ziel verfolgen, Software gemäß der ISO Norm 9241/10 zu evaluieren. Im Rahmen eines experimentellen Designs beurteilten 50 Versuchspersonen die U...

This paper makes seven recommendations to HCI researchers wishing to construct Fitts’ law models for either movement time prediction, or for the comparison of conditions in an experiment. These seven recommendations support (and in some cases supplement) the methods described in the recent ISO 9241-9 standard on the evaluation of pointing devices. In addition to improving the robustness of Fitt...

We present two studies using ISO 9241-9 to evaluate target pointing in two different 3D user interfaces. The first study was conducted in a CAVE, and used the standard tapping task to evaluate passive haptic feedback. Passive feedback increased throughput significantly, but not speed or accuracy alone. The second experiment used a fish tank VR system, and compared tapping targets presented at v...
