Enhancing Subtitle Features in Mobile Apps: Analyzing User Reviews for Accessibility and Usability Insights

While the benefits of subtitles for comprehension are widely acknowledged, empirical research has largely neglected the insights offered by user reviews of mobile applications. This study presents a comprehensive analysis of user feedback on subtitle features in the top 230 mobile applications across various categorie…

Investigating User Perceptions of Epilepsy-Related Seizure Triggers in Mobile Apps: An Analysis of User Reviews

Individuals with reflex epilepsy may have seizures caused by stimuli including flashing lights, colors, motion, and patterns. Many studies have investigated seizure-inducing content in multimedia, but studies addressing seizure triggers in mobile apps are still scarce. Hence, we examined user reviews aiming to identif…

Empirical Investigation of Accessibility Bug Reports in Mobile Platforms: A Chromium Case Study

Accessibility is an important quality factor of mobile applications. Many studies have shown that, despite the availability of many resources to guide the development of accessible software, most apps and web applications contain many accessibility issues. Some researchers surveyed professionals and organizations to u…

Analyzing Accessibility Reviews Associated with Visual Disabilities or Eye Conditions

Accessibility reviews collected from app stores may contain valuable information for improving apps accessibility. Recent studies have presented insightful information on accessibility reviews, but they were based on small datasets and focused on general accessibility concerns. In this paper, we analyzed accessibility…

Unveiling Practices of Customer Service Content Curators of Conversational Agents

Conversational interfaces require two types of curation: \textit{data curation} by data science workers and \textit{content curation} by domain experts. Recent years have seen the possibilities for content curators to instruct conversational machines in the customer service domain (i.e., Machine Teaching). The acti…

Don't Disturb Me: Challenges of Interacting with Software Bots on Open Source Software Projects

Software bots are used to streamline tasks in Open Source Software (OSS) projects' pull requests, saving development cost, time, and effort. However, their presence can be disruptive to the community. We identified several challenges caused by bots in pull request interactions by interviewing 21 practitioners, includi…

A Probabilistic Interpretation of Motion Correlation Selection Techniques

Motion correlation interfaces are those that present targets moving in different patterns, which the user can select by matching their motion. In this paper, we re-formulate the task of target selection as a probabilistic inference problem. We demonstrate that previous interaction techniques can be modelled using a Ba…

The Power of Bots: Understanding Bots in OSS Projects

Leveraging the pull request model of social coding platforms, Open Source Software (OSS) integrators review developers' contributions, checking aspects like license, code quality, and testability. Some projects use bots to automate predefined, sometimes repetitive tasks, thereby assisting integrators' and contributors…
