An analysis on tools for accessibility evaluation in mobile applications

Abstract

This research aims at identifying if current code validation tools contemplate the requirements of a guideline for the development of accessible mobile applications, called GUAMA, which was specified by our team over 3 years of research with visually impaired individuals and whose final conception process is formalized in this paper. Then, several tools were analyzed and two of them were chosen for a deeper study: Lint and Espresso. The results showed that Lint and Espresso respectively contemplate 12 and 6 from the 48 GUAMA requirements. Thus, the unique use of such tools is not adequate to validate the range of requirements. These results have motivated the investigation of a new integrated service/process, which presents a higher coverage regarding the validation of accessibility requirements.
