Which of the following groups of assistive technology users are supported by ARIA?

The answer is supported because ARIA, which stands for Accessible Rich Internet Applications, is specifically designed to enhance the accessibility of web content for assistive technologies. It provides a set of attributes that can be added to HTML elements to improve the semantic meaning and roles of those elements, particularly for users who rely on screen readers.

Screen readers are a primary form of assistive technology, translating web content into speech for users who are blind or visually impaired. By using ARIA, developers can convey additional information, such as roles, states, and properties, which enables screen readers to interpret and communicate content effectively. This enhances the navigational experience and interactivity of web applications for these users, thereby significantly benefiting their overall accessibility experience.

While users of screen magnifiers, text-to-speech applications, and hearing aids may also experience some benefits from properly implemented ARIA, the primary focus and intended support of ARIA are for users who navigate web pages using speech recognition or keyboard-only methods, and primarily, for those who use screen readers to access web content. This focus on dynamic web content and interaction aligns ARIA directly with the needs of these specific groups of assistive technology users.
