Képernyolvasók

Képernyolvasók are software applications that enable visually impaired or blind individuals to access and interact with digital content by reading aloud the text displayed on a computer screen or mobile device. They typically function by interpreting the graphical user interface (GUI) elements and converting them into synthesized speech. This allows users to navigate operating systems, web pages, applications, and other digital media through auditory feedback.

The core functionality of a képernyolvasó involves detecting changes on the screen, identifying text, icons, and other interface elements, and then communicating this information to the user. Users can often control the speed and pitch of the speech, as well as select different voices. Advanced képernyolvasók can also provide information about the structure of a document, such as headings, lists, and links, enabling more efficient navigation.

Commonly used képernyolvasók include JAWS (Job Access With Speech) and NVDA (NonVisual Desktop Access) for Windows, VoiceOver for macOS and iOS, and TalkBack for Android. These tools are essential for promoting digital inclusion and ensuring that everyone has equal access to information and online services. They are typically operated using keyboard commands, as traditional mouse interaction is not feasible for users who cannot see the screen.
