Graphical User Interface

A type of computer interface that uses visual elements such as windows, icons, menus, and pointers to allow users to interact with software, as opposed to text-based command-line interfaces. GUIs present significant accessibility challenges for blind and low-vision users because the visual layout conveys meaning that must be translated into non-visual formats. Screen readers use techniques like off-screen models and accessibility APIs to intercept graphical information and present it as text or speech, enabling non-visual access to GUI-based applications.
