“…Lastly, satisfaction means that the user should feel gratified when using the system. Moreover, in the ISO 9241-11, usability is defined as the level where a product can be utilized by a given user in achieving a specific objective with efficiency, effectiveness, and satisfaction in a defined context [23,24].…”

Among software quality attributes "software usability" is considered as one of the vital factors in software engineering literature. Software usability is the ability for users to generally understand, use, and learn a software with ease. Due to the importance of usability in software quality, a considerable amount of literature is published in the past decade. Few review and survey studies are also published to critically review the existing literature in the domain. However, there is limited research covering systematic mapping study of software usability. Mapping studies help in analyzing the general trends and research productivity in a research area. To fill this gap, this work critically examines the overall research productivity, demographics, trends, and challenges of software usability. The objective is to classify the current contributions and trends in the area of software usability. We retrieved 9,874 research articles from six research databases and 62 works are selected as primary studies using an evidence-based approach. The result of this mapping study shows that software usability is an active research area, with a promising number of works published in the last decade (2011 -2020). We identified that the current literature spans over multiple article classes of which investigative papers, model proposals and evaluation papers are the most frequently published article types. We found experiments and theoretical validations to be the most common validation techniques. In terms of application domains; web, software development and mobile applications are the most frequent domains where usability studies are conducted. We identified that future usability studies should focus more on field studies as well as on the usability testing of scientific software packages. It will be of importance to consider ethical issues in usability testing as well.

“…These psychophysical concerns and other sensory issues cannot be ignored given that XR devices should be accessible to all. A cross-cutting concept that is relevant to all of the above is cognitive load [145] (i.e., people have more trouble processing or remembering things if there is too much information [46,138,146], or too much interaction [147]). For example, in visual realism studies, it has been demonstrated that a selective representation of photo textures (a 'reduced realism') informed by navigation theories fulfills tasks such as route learning better than fully photorealistic alternatives [46,138,147].…”

This manuscript identifies and documents unsolved problems and research challenges in the extended reality (XR) domain (i.e., virtual (VR), augmented (AR), and mixed reality (MR)). The manuscript is structured to include technology, design, and human factor perspectives. The text is visualization/display-focused, that is, other modalities such as audio, haptic, smell, and touch, while important for XR, are beyond the scope of this paper. We further narrow our focus to mainly geospatial research, with necessary deviations to other domains where these technologies are widely researched. The main objective of the study is to provide an overview of broader research challenges and directions in XR, especially in spatial sciences. Aside from the research challenges identified based on a comprehensive literature review, we provide case studies with original results from our own studies in each section as examples to demonstrate the relevance of the challenges in the current research. We believe that this paper will be of relevance to anyone who has scientific interest in extended reality, and/or uses these systems in their research.

“…Finally, a more recent work from Carvajal et al 23 introduces a set of usability guidelines to determine the responsibility of different usability mechanisms in an Model‐View‐Controller (MVC) architecture and to study the impact of supporting specific usability features as a way to help developers during the analysis and design of usability use cases, class, and sequence diagrams. Finally, one recent work 24 describes an experiment with 168 users on the impact of three usability mechanisms (Abort operation, Progress feedback, and Preference) on efficiency, effectiveness and user satisfaction. The authors describe how the adoption of each usability mechanism impacted these qualities.…”

Usability implications in software architecture: The case study of a mobile app

et al. 2020

Usability is a highly desired but often ignored software quality. Effective user interfaces tend to increase learnability, effectiveness and user satisfaction. But usability is often neglected in the early stages of software development and is thus frequently not address in a system's architectural design. Furthermore, because usability is often neglected or deferred, it is difficult to estimate the effort specifically spent on adding or improving usability mechanisms in the software architecture and in code. In this work, we present a case study where we analyze the impact of introducing a variety of usability mechanisms to a mobile application and we report on the architectural changes that must be made in the software architecture to accommodate them. We also report on the additional code required to implement these usability mechanisms and we investigate the users' satisfaction of combining and using several usability mechanisms in a mobile application. Finally, we evaluated user responses—both positive and negatives—to these usability mechanisms via a questionnaire involving 25 users from different roles and different organizations and including contextual interviews to analyze the qualitative responses of the subjects. Our results show that apart from the relatively modest modeling and coding effort, the combination of several usability mechanisms seems beneficial for users of mobile systems and increases the satisfaction during the interaction with the system.
