Abstract
The objective of this scoping review is to characterize the current scenario of mobile applications considering accessibility issues for people with cognitive, motor, and sensory disabilities. Nowadays, mobile devices have grown exponentially, giving way to new ways of relating, managing, and working. In this context, mobile devices seek to democratize access to knowledge on different topics; however, the application of accessibility guidelines is neglected. The reviewers extracted the most relevant articles published between 2000 and 2020 from the ACM Digital Library, IEEE Xplore, ScienceDirect, Scopus, and Web of Science databases. In this scoping review, the PRISMA-ScR checklist was used to extract scientific articles; Cohen’s kappa coefficient = 0.4117 was applied, which implies moderate concordance of reviewers; 22 primary studies were extracted from a total of 211. The results obtained in this research suggest applying WCAG 2.1 in mobile applications to achieve an adequate level of accessibility. Future work suggests designing review tools that include machine learning based on artificial intelligence algorithms.
Highlights
Today, the web presence is no longer enough; digital media consumption is higher on mobile devices; in this digital age, mobility and the Internet allow unlimited possibilities to connect people with various activities
This section answers the six research questions initially posed by (1) a bibliometric assessment to compile publication records by year on the increase in research over time from journals, conferences, books, and book chapters on accessibility and mobile apps and (2) a scoping review to map studies according to the perceptions of accessibility and mobile applications
To record the characteristics of the primary studies, we considered the six research questions that include: (1) investigate the disability types of accessible mobile applications developed between 2000 and 2020; (2) classify the methods and techniques used in the design of accessible mobile devices; (3) identify accessibility guidelines that apply to mobile applications; (4) categorize the types of research and impact on accessible mobile applications; (5) reveal the most used tools for evaluating accessibility in mobile applications; and
Summary
The web presence is no longer enough; digital media consumption is higher on mobile devices; in this digital age, mobility and the Internet allow unlimited possibilities to connect people with various activities. Known as apps, offer organizations valuable content, management, and interaction from any device. Mobile applications are designed to be employed on intelligent devices or tablets; they can be transferred from a device company’s distribution platform. This scoping review has identified several publications related to mobile applications that do not consider accessibility for users with disabilities. This study’s need is justified to (1) find information on relevant research on mobile applications and accessibility; (2) categorize whether any accessibility guidelines are applied; (3) detect the different approaches to mobile applications for cognitive, motor, and sensory disabilities;. The results of the studies indicated that the apps present several accessibility barriers that need to be improved
