Review Questions

• How do screen readers enhance digital accessibility for visually impaired users?
  • Screen readers enhance digital accessibility by converting on-screen text into speech or braille, which allows visually impaired users to interact with digital content. They provide auditory feedback, enabling users to navigate through websites and applications effectively. Additionally, screen readers facilitate access to documents and other text-based resources, ensuring that individuals with visual impairments can participate in the digital world on equal footing with others.
• Discuss the importance of using proper coding techniques for websites to ensure compatibility with screen readers.
  • Using proper coding techniques is vital for ensuring that websites are compatible with screen readers. Semantic HTML helps structure content in a way that screen readers can interpret accurately, allowing them to convey meaning effectively. For example, using heading tags correctly not only organizes content but also assists screen readers in identifying the hierarchy of information. When websites are designed with accessibility in mind, it significantly improves the user experience for visually impaired individuals and promotes inclusivity.
