Graphical User Interface

A visual interface paradigm based on windows, icons, menus, and pointer (WIMP) interaction, which became dominant in personal computing from the late 1980s onward. GUIs represented a major accessibility challenge when they replaced text-based command lines: screen readers designed for character-mode displays could not interpret visual layouts, icons, or mouse-dependent interactions. Making GUIs accessible required fundamental rethinking of screen reader technology, development of accessibility APIs (like MSAA, IAccessible2, and UI Automation), and extensive keyboard navigation support. The transition from DOS to Windows GUI accessibility took years and established the pattern of assistive technology "catching up" to mainstream interface changes.
