A Systematic Evaluation of Mobile Applications for Instant Messaging on iOS Devices

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.

Accessibility in video games: a systematic review

Video games are software products with several purposes that are growing in strength and weight in society. However, there is one noticeable problem about them; in most cases, their developers most often do not take into consideration people with disabilities when they are creating video game applications. People with disabilities are thus partially or completely excluded from their use. Prior to any additional work, it is required to have an updated state of the art about this topic. This paper shows the results of a systematic literature review conducted to define the current status of video games accessibility. The type of review is broader than usual, so it is a systematic mapping study (a specific class of systematic review). Besides elaborating the state of the art (qualitative information), we identified and analyzed related works (45 relevant studies) to provide quantitative information of the performed search (including graphs and tables), such as the number of articles found by phases, their sources, their research type, the research questions answered, the kind of disability addressed, and the type and year of publications. None of the studied initiatives can guarantee universally accessible video game applications. Our proposal is to create an integral software engineering methodology that considers accessibility guidelines, techniques, strategies, human factors, etc. in the video game software development process.
