Synonyms
Graphical User Interface, User Interface, UI, Interface design, Screen design, Graphical interface
A GUI (graphical user interface) is a visual interface through which users interact with a computer or a software programme. Instead of entering commands as text (as with a command line), a GUI allows interaction via graphical elements such as:
- Windows
- Icons
- Buttons
- Menus
- Text fields
- Sliders
These elements can be operated by mouse, keyboard or touchscreen, which often makes use more intuitive and user-friendly. Examples of GUIs are the interfaces of operating systems such as Windows or macOS, as well as apps on smartphones.
GUIs have made using computers considerably easier, as they provide access to complex functions without in-depth technical knowledge.
