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.

Recent advances in medical interventions have changed the prognosis for children with infantile-onset spinal muscular atrophy (SMA-1); however, little has been published regarding rehabilitation management. A rapid scoping review was conducted in November 2020 using Medline and CINAHL databases. Evidence supporting use of assistive devices and equipment to enhance participation, mobility, function, and posture in lying, sitting, and standing positions was sought. From 239 articles, only five studies (describing use of augmentative communication, manual and power mobility, supported standing and orthotic devices) met inclusion criteria. Results are presented alongside a case report of a 5-year-old boy (treated with Nusinersen since 7 months-of-age) who uses a variety of devices to enhance his activity and participation in family life. While reclined and tilted sitting positions as well as power mobility were previously considered for children with SMA-1, this child has progressed to supported upright standing, self-propelling a lightweight manual wheelchair indoors, communicating using multiple methods and taking steps in a dynamic mobility device. Power mobility was introduced in a switch-adapted cart at 11 months and he was independently exploring indoors and outside in his power wheelchair before 20 months. Research evidence is limited, but alongside the case report highlights the importance of a comprehensive and proactive approach to enhancing function, fun and participation with family and friends through adaptive equipment for children with significant and life-limiting disabilities.
