“…The design of the application should pay close attention to the interface, even more than the functionality itself. In words of [25], the UI design should not be done at the end. The app should be tested in every screen rotation (vertically and horizontally) and with different screen sizes to ensure that all elements of the app are properly displayed, the main problems described in [63].…”

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.

“…Recently, however, some authors have identified several usability features strongly related to functionality [4]. These features do not only affect interfaces but also architecture, and are hard to deal with if they are not considered from the early stages of development.…”

“…In [4], authors present three groups of recommendations: (1) Usability recommendations with impact on the user interface; (2) Usability recommendations with impact on the development process; (3) Usability recommendations with impact on the architectural design. These last recommendations involve building certain functionalities into the software to improve user-system interaction.…”

Abstract. Usability plays an important role to satisfy users' needs. There are many recommendations in the HCI literature on how to improve software usability. Our research focuses on such recommendations that affect the system architecture rather than just the interface. However, improving software usability in aspects that affect architecture increases the analyst's workload and development complexity. This paper proposes a solution based on model-driven development. We propose representing functional usability mechanisms abstractly by means of conceptual primitives. The analyst will use these primitives to incorporate functional usability features at the early stages of the development process. Following the model-driven development paradigm, these features are then automatically transformed into subsequent steps of development, a practice that is hidden from the analyst.

Set-top box (STB) is a special interface device that is connected to a TV and allows digital content to be received, decoded, and displayed on the TV. The new features added to STB&TVs increase the complexity of the systems and lead to usability problems. This study proposes a set of usability heuristics and their corresponding criteria specific to STB&TV interfaces that usability experts may use during the design and evaluation process. In this study, a total of 493 usability problems were collected from three sources: problems identified by software developers during the design and development phase, problems identified by three experts with cognitive walkthrough approach, and problems collected from customer complaints made to the service or call center. Then, each heuristics' checklist item was rated by the experts for how well they explain the usability problems, and the severity levels of the usability problems were determined. In the next step, through correspondence and cluster analyses, heuristics and the checklists were listed in descending order of severity. Furthermore, the proposed heuristic list was validated with three methods-user testing, expert judgment, and heuristic evaluation. As a result of this study, 16 usability heuristics were identified. Five of these heuristics-Visibility of system status (H4), Pleasurable and respectful interaction with the user (H13), Privacy (H14), Parental control (H15), and Easy access (H16) are related to catastrophic usability problems.
