Análise e Redesign da ferramenta de validação de acessibilidade para ambientes web IBM Equal Access Accessibility Checker
| Resumo: | The lack of adequate support for people with disabilities in using digital products remains a reality. In response, several countries have been strengthening accessibility legislation and standards to ensure greater inclusion for all. In this context, accessibility validation tools play an essential role in supporting designers and developers in identifying and correcting barriers, thereby contributing to the development of more inclusive digital products. However, validation tools still need to be improved. In this sense, the present work aims to analyze and redesign the IBM Equal Access Accessibility Checker tool, comparing it with existing tools and with the current version of the tool. The work began with a literature review, a comparative analysis of features and usability, as well as a heuristic evaluation and SWOT analysis of the IBM Equal Access tool, carried out by seven evaluators. Subsequently, the results of the studies were collected and, taking into account the needs of users, a list of concrete and detailed requirements was defined. Next, the visual identity of the new version of the tool was defined and low, medium, and high-fidelity prototypes were designed, following a human-centered design methodology. Finally, to validate the interface of the IBM Equal Access tool, a usability and user experience evaluation was carried out with 10 participants, divided into two groups. The participants completed all tasks with a minimum number of errors, obtaining an average score of 88,75 on the System Usability Scale.The results of this dissertation contribute to the field of digital accessibility by presenting a more effective and user-friendly solution for the IBM Equal Access tool, centered on the human being. They also contribute to improving the set of available resources by offering a list of requirements derived from the analysis of six validation tools, which can guide the creation and redesign of future tools. |
