Análise de problemas de funcionalidade e usabilidade no processo de desenvolvimento do software leitor de telas livre nvda

Abstract

This paper presents an investigative analysis of the software development process of the free screen reader NVDA to identify which functionality and usability problems are presented as critical factors for the success and growth of the use of this software for visually impaired users. By means of the verification, classification and study of a significant number of reports of errors or enhancement requests collected in its global community of users public platform, it was possible to list and display what are the critical factors of usability that are paramount for the success and expansion of the use of this software. Usability issues related to the flexibility of use, viewing system status and consistency of actions were those that presented more problems and that impacted the most the use of the system. Although the perception of low-priority for usability problems, no significant differences were found in the treatment of problems of usability and functionality of the project analyzed. The presentation of these results helps to understand the bottlenecks existing in this type of software usability. Thus, these findings may encourage the development of more satisfactory software for users of Assistive Technology, allowing to leverage the growth of this global community of users.
