What was the purpose of designing Active Accessibility?

The purpose of designing Active Accessibility is indeed to facilitate applications for people with visual or hearing impairments. Active Accessibility provides a set of tools and interfaces that allow software applications to expose their user interface elements in a way that accessibility aids, such as screen readers, can interpret and present to users with disabilities. This system ensures that users who rely on assistive technology can interact with applications effectively, enhancing their user experience and promoting inclusivity in software design.

The other options, while important in their own contexts, do not align with the primary focus of Active Accessibility. For instance, improving application performance and enabling faster software development pertain to different aspects of software engineering and optimization, while securing applications from unauthorized access relates specifically to security measures rather than accessibility.
