“…Furthermore, detecting all usability issues in this kind of experiment is not possible because the context of use is not taken into account [27,44] but, on the contrary, when applying experiments in the laboratory, there is more control over the usability issues detected.…”

Nowadays, instant messaging applications (apps) are one of the most popular applications for mobile devices with millions of active users. However, mobile devices present hardware and software characteristics and limitations compared with personal computers. Hence, to address the usability issues of mobile apps, a specific methodology must be conducted. This paper shows the findings from a systematic analysis of these applications on iOS mobile platform that was conducted to identify some usability issues in mobile applications for instant messaging. The overall process includes a Keystroke-Level Modeling and a Mobile Heuristic Evaluation. In the same trend, we propose a set of guidelines for improving the usability of these apps. Based on our findings, this analysis will help in the future to create more effective mobile applications for instant messaging.

“…The goal of usability testing is to assess the degree to which a system is effective and efficient and favours positive attitudes and responses from the intended users. 4 Participants are invited to undertake typical tasks that may or may not be simulated whilst their behaviours are observed and recorded. Should design problems be identified, recommendations are proposed that may improve the quality of the product and tailor the product to the usersÕ preferred ways of working.…”

Objectives The aim of this study, which was part of the first independent evaluation of patient reporting of adverse drug reactions (ADRs) to the Yellow Card Scheme, was to observe the three reporting systems (paper, internet and telephone) Ôin useÕ in a simulated setting to identify aspects which facilitated or hindered reporting.Methods Forty adult participants were recruited from the general public using posters in pharmacies and a press article, and from a pool of volunteer simulated patients maintained by University of Nottingham medical and pharmacy schools. The participants, in seven groups that met at different times, were asked to Ôthink aloud,Õ as they were individually observed completing the reporting process for the paper and internet system, highlighting their thoughts and any issues encountered. They were asked to talk about their experience of reporting immediately after they had reported by telephone. Data from the field notes were analysed thematically and supplemented with relevant information from digital audio recordings.Conclusions Usability testing using the Ôthink aloudÕ approach worked well and identified areas of the Yellow Card reporting system which could be improved. Whilst the three methods of reporting available to the public are all reasonably Ôfit for purposeÕ, there were many suggestions identified for improving ease of completion and data quality, especially for the internet system.

“…User-based testing involves observation of end-users to evaluate ease of navigation, interaction with application features, ability to perform essential functions, and satisfaction with task flow [17]. User-based testing of the PRO-CTCAE software was performed with patients receiving systemic cancer treatment and among professional users (physicians, nurses and clinical research associates [CRAs]).…”

BACKGROUND The US National Cancer Institute (NCI) developed software to gather symptomatic adverse events directly from patients participating in clinical trials. The software administers surveys to patients using items from the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) through Web-based or automated telephone interfaces and facilitates the management of survey administration and the resultant data by professionals (clinicians and research associates). OBJECTIVE The purpose of this study was to iteratively evaluate and improve the usability of the PRO-CTCAE software. METHODS Heuristic evaluation of the software functionality was followed by semiscripted, think-aloud protocols in two consecutive rounds of usability testing among patients with cancer, clinicians, and research associates at 3 cancer centers. We conducted testing with patients both in clinics and at home (remotely) for both Web-based and telephone interfaces. Furthermore, we refined the software between rounds and retested. RESULTS Heuristic evaluation identified deviations from the best practices across 10 standardized categories, which informed initial software improvement. Subsequently, we conducted user-based testing among 169 patients and 47 professionals. Software modifications between rounds addressed identified issues, including difficulty using radio buttons, absence of survey progress indicators, and login problems (for patients) as well as scheduling of patient surveys (for professionals). The initial System Usability Scale (SUS) score for the patient Web-based interface was 86 and 82 (P=.22) before and after modifications, respectively, whereas the task completion score was 4.47, which improved to 4.58 (P=.39) after modifications. Following modifications for professional users, the SUS scores improved from 71 to 75 (P=.47), and the mean task performance improved significantly (4.40 vs 4.02; P=.001). CONCLUSIONS Software modifications, informed by rigorous assessment, rendered a usable system, which is currently used in multiple NCI-sponsored multicenter cancer clinical trials.
