“…Formative test sessions are often less formal with greater interaction between participants and moderator. Formative tests collect mainly qualitative data especially during the earlier cycles, although some quantitative data such as error rate may also be collected [35]. After a series of iterative formative testing, the number of which might depend on the amount of issues detected by participants interacting with the system, summative testing may be conducted.…”

“…Self-and observer-reported metrics may suffer from bias as participants often consider their responses and are conscious of their actions and may not act as they would in real life [40,41]. Implicit metrics which are less commonly used may provide the most unbiased data as they measure participants' unconscious behaviours and physiology [35]. These include eye tracking and pupillary dilation [42].…”

“…Time required for completing tasks, numbers of clicks to complete tasks, and cost effectiveness are appropriate metrics for efficiency. Overall satisfaction rates and proportion of users reporting complaints can be used to assess satisfaction [35]. While effectiveness, efficiency and satisfaction are often assessed quantitatively, they could also be assessed qualitatively.…”

“…For example, effectiveness could be assessed by discussing errors and successful task completions with participants. Participants could also describe their satisfaction with the system in their own words [35].…”

Introduction Recent advances in information technology and improved access to the internet have led to a rapid increase in the adoption and ownership of electronic devices such as touch screen smartphones and tablet computers. This has also led to a renewed interest in the field of digital health also referred to as telehealth or electronic health (eHealth). There is now a drive to collect these PROs electronically using ePRO systems. Method However, the user interfaces of ePRO systems need to be adequately assessed to ensure they are not only fit for purpose but also acceptable to patients who are the end users. Usability testing is a technique that involves the testing of systems, products or websites with participants drawn from the target population. Usability testing can assist ePRO developers in the evaluation of ePRO user interface. The complexity of ePRO systems; stage of development; metrics to measure; and the use of scenarios, moderators and appropriate sample sizes are key methodological issues to consider when planning usability tests. Conclusion The findings from usability testing may facilitate the improvement of ePRO systems making them more usable and acceptable to end users. This may in turn improve the adoption of ePRO systems post-implementation. This article highlights the key methodological issues to consider and address when planning usability testing of ePRO systems.

“…The patient-oriented design focuses on preventing or controlling a disease known to be of great importance in work-oriented approaches (Reis et al, 2011). The usability test is a one-step design experiment in which designers technically evaluate the background of a product to grasp a better design (Geisen & Romano Bergstrom, 2017;Rosson & Carroll, 2002). In these usability tests, a user is tested in interaction with a product to determine the efficiency of the product (Lee & Ha, 2019).…”

The aim of this study is to investigate the usability of conventional masks to prevent the transmission of coronavirus 2019 (COVID-19) and subsequently design the proposed concept of the mask to reduce leakage and increase efficiency. Acute respiratory syndrome COVID-19 is spreading around the world and can be transmitted from one person with COVID-19 to another through personal contact and breathing. Improper design of current masks can lead to virus transmission. One hundred fifteen users participated in the study using a simple random sampling method in which N95-FFP2 face mask and surgery face mask usability tests were chosen as the most widely used face masks in Iranian people with an online usability questionnaire. Data were analyzed by SPSS. The results showed that the usability of the N95-FFP2 face mask with a total average of 4.46 and a surgical mask with a total average of 3.35 cannot be considered acceptable. Anthropometric and formal changes in people's faces and improper design of the face masks used make it necessary to review the mask redesign measures to increase the prevention of pathogens. In this study, new parameters for face mask design are proposed. Thirty different types of jaws have been considered with the help of CorelDRAW software, along with ideas for optimal mask design with UVW mask concept to be accessed by manufacturers around the world.

A review of eye tracking research on video-based learning

Eye tracking technology is increasingly used to understand individuals’ non-conscious, moment-to-moment processes during video-based learning. This review evaluated 44 eye tracking studies on video-based learning conducted between 2010 and 2021. Specifically, the review sought to uncover how the utilisation of eye tracking technology has advanced understandings of the mechanisms underlying effective video-based learning and what type of caution should be exercised when interpreting the findings of these studies. Four important findings emerged from the analysis: (1) not all the studies explained the mechanisms underlying effective video-based learning through employing eye tracking technology, and few studies disentangled the complex relationship between eye tracking metrics and cognitive activities these metrics represent; (2) emotional factors potentially serve to explain the processes that facilitate video-based learning, but few studies captured learners’ emotional processes or evaluated their affective gains; (3) ecological validity should be improved for eye tracking research on video-based learning through methods such as using eye tracking systems that have high tolerance for head movements, allowing learners to take control of the pacing of the video, and communicating the learning objectives of the video to participants; and (4) boundary conditions, including personal (e.g. age, prior knowledge) and environmental factors (e.g. the topic of videos, type of knowledge), must be considered when interpreting research findings. The findings of this review inspire a number of propositions for designing and interpreting eye tracking research on video-based learning.
