Design and evaluation of mobile applications for people with visual impairments: a compilation of usable accessibility guidelines

In a context where the individual's daily needs and activities are increasingly focused on mobile devices, the use of sound design practices focused on technically accessible and cognitively usable interfaces becomes critical. This issue is even more sensitive when considered under the perspective of people with visual impairments, who depend on operating systems (OS) accessibility features. However, native OS accessibility support is not mature enough to ensure usability and accessibility simultaneously in different kinds of applications. To overcome these limitations, Human-Computer Interaction literature has been proposing guidelines, best practices, and heuristics for designing and evaluating usable and accessible designs. Still, this information is diffuse and can be challenging to implement because they were proposed considering different definitions and specifications. To support practitioners, students and researchers in finding and implementing usability and accessibility guidelines in mobile applications, the present work presents a compilation of 369 recommendations identified in the literature on the design and evaluation of usable and accessible interfaces for blind people on mobile devices.
