# User Interface
User interface, or UI, is an interface between human and computer. Such interface interacts with some of the human senses, i.e. it can be visual (text, images), auditory (sound), touch (haptic) etc.
Remember the following inequality:
*non-interactive [CLI](cli.md) > interactive [CLI](cli.md) > [TUI](tui.md) > [GUI](gui.md)*
