In [[computing]], '''Texttext-based user interfaces''' ('''TUI'''), (alternately '''terminal user interfaces''', to reflect a dependence upon the properties of [[computer terminalsterminal]]s and not just text), is a [[retronym]] paralleldescribing toa type of [[user interface]] (UI) common as an early form of [[human–computer interaction]], before the conceptadvent of [[graphical user interface]]s (GUIGUIs). Like GUIs, they may use the entire [[Electronic visual display|screen]] area and accept [[mouse (computing)|mouse]] and other inputs. They may also use color and often structure the display using special graphical characters[[Character (computing)|character]]s such as ┌ and ╣, referred to in [[Unicode]] as the "box drawing" set. The modern context of use is usually a [[terminal emulator]].
<!-- [[VisiCalc]] and the [[Emacs]] and [[vi]] [[visual editor]]s are the earliest examples of TUIs. -->
