Die vorliegende Fallstudie befasste sich mit der Effektivität von Usability-Tests als Methodik für die Gestaltung gebrauchstauglicher Software. Ein Online-Bookshop wurde zu zwei Zeitpunkten in einem Entwicklungszyklus mithilfe eines Usability-Tests evaluiert. Aus den im ersten Usability-Test identifizierten Usability-Problemen wurden Gestaltungskonsequenzen abgeleitet und umgesetzt. Die so überarbeitete zweite Version des Bookshops wurde einem weiteren Usability-Test unterzogen, in dem wiederum Usability-Probleme erhoben wurden. Die ausgewertete Stichprobe von 22 studentischen Versuchspersonen unterteilte sich in 11 Novizen und 11 Experten, 10 Probanden waren männlichen und 12 weiblichen Geschlechts. Von diesen 22 Probanden nahmen jeweils 11 an einem der beiden Usability-Tests teil, in denen die gleichen drei aufeinander aufbauenden Testaufgaben bearbeitet wurden. Die Befunde zeigen wie angenommen, dass sich die Quantität der erkannten Usability-Probleme vom ersten zum zweiten Usability-Test verringerte. Entgegen der Erwartung wurde jedoch keine Veränderung der Bedeutsamkeit der erhobenen Usability-Probleme verzeichnet. Entsprechend der Untersuchungsannahmen zeigt sich weiterhin ein Effekt der Kombination von Evaluation und Gestaltung auf die subjektive Bewertung von Gefallensaspekten und der ergonomischen Qualität des Bookshops durch die Nutzer. Zudem stellt sich die Expertise der Nutzer als relevanter Faktor für die Häufigkeit explizit geäußerter Kritik am Produkt dar. Konsequenzen für die Praxis und weitere Forschung im Bereich des Usability-Engineerings sowie die Notwendigkeit einer psychologisch begründeten Definition des Konstrukts des Usability-Problems werden diskutiert.

Conventional vascular intervention (VI) procedures are typically performed manually under exposure to X-rays, whereby several problems are presented that need to be addressed owing to the patients and doctors being exposed to large amounts of radiation. In such cases, employing radiation protection units is not a long-term solution to avoid physical damage. Therefore, to overcome these issues, we propose a robotic VI system in this study. Moreover, we compare the extent of radiation exposure in the case of the conventional manual VI procedure with that in the case of the robotic procedure. The radiation exposure is then analyzed from the perspective of the doctor. Subsequently, the results of usability tests for two proposed master devices are presented in terms of the NASA task load index (NASA-TLX) and the system usability scale (SUS) score. To verify the effectiveness of the robotic VI system, animal experiments are conducted using a pig model. Among the two types of master devices tested with the proposed robotic VI system, the ergonomically designed 2-degree-of-freedom master device is found to be more effective than the joystick-type device in terms of the usability test scores. Hence, the proposed robotic VI procedure is shown to be advantageous in terms of reducing radiation exposure and improving usability.

Road safety campaigns and programs have been extensively introduced and implemented in Malaysia. However, their effectiveness is still being debated. Children especially will become the unfortunate victims of road accidents if they are unaware of the danger and precaution actions to be safe on the road. In response to that, this paper introduces an application as an alternative that inculcates road safety awareness to further support existing related programs and campaigns. Particularly, an interactive web application incorporating interactive multimedia elements has been designed and evaluated. Results on the usability test indicate a promising success and highlight aspects and issues that can be further focused for improvement and enhancement.

<p>Discovery tools are emerging in libraries. These tools offer library patrons the ability to concurrently search the library catalog and journal articles. While vendors rush to provide feature-rich interfaces and access to as much content as possible, librarians wonder about the usefulness of these tools to library patrons. In order to learn about both the utility and usability of EBSCO Discovery Service, James Madison University conducted a usability test with eight students and two faculty members. The test consisted of nine tasks focused on common patron requests or related to the utility of specific discovery tool features. Software recorded participants’ actions and time on task, human observers judged the success of each task, and a post-survey questionnaire gathered qualitative feedback and comments from the participants.  Overall, participants were successful at most tasks, but specific usability problems suggested some interface changes for both EBSCO Discovery Service and JMU’s customizations of the tool.  The study also raised several questions for libraries above and beyond any specific discovery tool interface, including the scope and purpose of a discovery tool versus other library systems, working with the large result sets made possible by discovery tools, and navigation between the tool and other library services and resources.  This article will be of interest to those who are investigating discovery tools, selecting products, integrating discovery tools into a library web presence, or performing evaluations of similar systems.</p>

The University of Nevada Las Vegas Libraries engaged in three projects that helped identify areas of its website that had inhibited discovery of services and resources. These projects also helped generate staff interest in the Usability Working Group, which led these endeavors. The first project studied student responses to the site. The second focused on a usability test with the Libraries’ peer research coaches and resulted in a presentation of those findings to the Libraries staff. The final project involved a specialized test, the results of which also were presented to staff. All three of these projects led to improvements to the website and will inform a larger redesign.
