Abstract

The evolution of internet pages from a static and low-interactivity reality to a reality of rich applications, with increasingly interactive interfaces, provide remote user access to some services previously performed in person. Faced with this evolution, users with disabilities begin to depend more and more on assistive technologies such as screen readers to be able to interact with these applications that must be planned and built taking into account the limitations that these users have, offering simple alternatives of interaction. These applications, however, do not have a standardization in the form of their development, screen readers have difficulties in reading the content and the user starts to face problems in the interaction. A solution offered by the W3C was the creation of accessibility standards and guidelines such as WCAG and WAI-ARIA that, if followed, help the developer in creating rich applications with accessibility, offering elements to screen readers allowing the interaction of the disabled user. through the keyboard. However, the state of the art shows that website developers have little or no knowledge about these guidelines and standards, therefore, even though there are ways to offer accessibility, many developers do not implement them, resulting in the emergence of accessibility barriers that harm and/or prevent the use of these applications by users with disabilities. Conducting this exploratory research on the 500 most accessed websites in the world according to ALEXA, identifying the standards, accessibility guidelines implemented by website developers. In the results, it was possible to verify the reasonable amount of WAI-ARIA attributes used in 384 sites out of the 500 made available by ALEXA, indicating that many sites need to improve their
