Resumo

When applications intend to support accessibility, several aspects of interface design and usability must be reviewed to adapt or extend common functional requirements that are implemented to ensure an easy use of applications. However, initiatives to develop guidelines for accessible mobile applications are recent and several approaches present only suggestions rather than a concrete list of requirements. This work focuses on accessibility requirements for visually impaired users and it is part of a broader effort that involves different types of impairments. Our research method was based on three main steps. First, from an initial set of 1014 scientific and technical articles, 46 were analyzed to identify requirements that are related to visual impairments. Second, we carried out an observation-based analysis to confirm the importance of these requirements, considering a set of accessibility tests with impaired volunteers. Third, the Design Thinking process was used to implement an application prototype, considering the most important requirements that were identified along the two first steps. This application was submitted to a user-centered evaluation with volunteers, which also supported the evolution of our requirements. As result, this paper presents the complete roadmap of this process, which resulted in a guideline and evaluation method to support the integration of accessibility aspects into mobile applications.
