Text-based User Interface (TUI) refers to a type of user interface that utilizes text and characters rather than graphical elements to interact with users. Unlike Graphical User Interfaces (GUIs), which rely on graphical elements such as icons, windows, and buttons, TUIs primarily use text and are often character-based.
Key characteristics of a Text-based User Interface (TUI) include:
- Text Representation. TUIs present information and receive user input through text characters. This can include displaying menus, prompts, and other textual information.
- Command-Line Interfaces (CLI). Command-line interfaces are a common form of TUI where users interact with a program by typing commands. The system then processes these commands and provides textual output.
- Ascii Art and Box-drawing Characters. TUIs often use ASCII art and special characters for creating basic graphics and dividing sections of the interface. Box-drawing characters are commonly employed for creating simple borders and boxes.
- No Graphics or Images. Unlike GUIs, TUIs typically do not include graphical elements, images, or multimedia content. Interaction is based on keyboard input and textual responses.
- Resource Efficiency. TUIs are often more resource-efficient compared to GUIs, making them suitable for environments with limited system resources or for remote access scenarios.
- Scripting and Automation. TUIs are conducive to scripting and automation, as commands can be easily scripted using text-based languages, providing a way to automate repetitive tasks.
- Accessibility. TUIs can be more accessible for users who rely on screen readers or other assistive technologies, as they rely on text that can be easily converted into speech.
Examples of TUIs include command-line interfaces in operating systems (e.g., Windows Command Prompt, Linux Terminal), text-based web browsers, and certain application interfaces that operate primarily with text.
In summary, TUIs provide a means of interacting with software through text characters, and they are often associated with command-line interfaces and environments where graphical elements are not practical or necessary.
