“…To test the usability of the three apps we used the System Usability Scale (SUS) (see Table 2). The SUS is a free technology agnostic survey with a ten-item, five-point Likert scale, providing a subjective assessment of system usability in a quick way (Brooke 1996;Grier et al 2013). Our investigations showed that the SUS instrument was among the most statistically robust and validated tools, which is also suggested by Bangor et al (2008).…”

Usability testing with mobile applications (apps) plays an important role in determining the ease of use of an app as well as in informing their design and development. The purpose of this research is to investigate the usability of three language learning apps with a sample of Arabic speaking migrants who have recently arrived to Sweden. In addition, We surveyed available apps for the target group on both Android and Apple market stores and used a framework for categorizing language learning apps to guide the design and development of our own app. The outcomes show that in order for users to engage in an app, there are a number of obstacles that need to be overcome to make an app motivating enough to use, such as lack of variation in functionality, instructions and feedback. Our app, Minclusion, was developed from the input obtained from the usability studies.

“…The results are in line with earlier findings showing a positive correlation between the SUS scores and the scale (r 0.75). Previous studies have found correlations of 0.822 Bangor, Kortum, and Miller (2009), 0.94 Ghosh et al (2018), and 0.848 Grier et al (2013). However, in these earlier studies they were comparing the usability of 2 or more systems.…”

Owing to increasing cases of sedentary lifestyles and their negative impact on health, practical solutions are needed to address the physical and mental wellbeing of citizens and to enhance their standard of living. Among the problems are premature mortality rates caused by physical inactivity, which leads to chronic diseases. Innovative solutions are needed to address many of the problems that we face as a society. Location-based games have been identified as effective solutions for increasing physical activity, enhancing social interaction, and exploration in urban environments. In this pilot study, we explore how to encourage active mobility (walking and cycling) through urban play by integrating technology into the built environment. We examined the usability of a web-based augmented reality application in providing interactive experience to users as they explored the urban environment looking for tasks. Overall, participants’ perceptions of the usability of the application were positive; they enjoyed how the application revealed the tasks at each location and all the checkpoints at the different locations had at least a couple of visitors. We present limitations and future research directions.

“…Cognitive load refers to the overall task load calculated, using the NASA-TLX questionnaire, for six defined variables (mental demand, physical demand, temporal demand, performance, effort, and frustration) [ 28 ]. Usability was calculated using the System Usability Scale (SUS) questionnaire [ 29 ]. SUS is a simple, ten item questionnaire that records a user’s subjective assessment of usability.…”

Usability of Graphical Visualizations on a Tool-Mounted Interface for Spine Surgery

et al. 2021

Screw placement in the correct angular trajectory is one of the most intricate tasks during spinal fusion surgery. Due to the crucial role of pedicle screw placement for the outcome of the operation, spinal navigation has been introduced into the clinical routine. Despite its positive effects on the precision and safety of the surgical procedure, local separation of the navigation information and the surgical site, combined with intricate visualizations, limit the benefits of the navigation systems. Instead of a tech-driven design, a focus on usability is required in new research approaches to enable advanced and effective visualizations. This work presents a new tool-mounted interface (TMI) for pedicle screw placement. By fixing a TMI onto the surgical instrument, physical de-coupling of the anatomical target and navigation information is resolved. A total of 18 surgeons participated in a usability study comparing the TMI to the state-of-the-art visualization on an external screen. With the usage of the TMI, significant improvements in system usability (Kruskal–Wallis test p < 0.05) were achieved. A significant reduction in mental demand and overall cognitive load, measured using a NASA-TLX (p < 0.05), were observed. Moreover, a general improvement in performance was shown by means of the surgical task time (one-way ANOVA p < 0.001).
