The main graphical input devices are scanner and light pen.

respond to user input.
Interactive input devices are those that give the user feedback as they are used to feed in data. An example is a touchscreen, which doubles up as an output device.
Scratch is not an input or output device; it is a visual programming language and online community designed for creating interactive stories, games, and animations. Users input commands and code through a graphical interface, which allows them to create projects that can produce visual and audio output. Essentially, Scratch serves as a platform for programming rather than a physical device.
A type of user interface that is not commonly recognized is a "non-interactive interface." Unlike graphical user interfaces (GUIs), command-line interfaces (CLIs), and touch interfaces, a non-interactive interface does not allow user input or interaction, making it ineffective for user engagement. Instead, it may only provide information or display content passively.

GUI (Graphical User Interface)?
The INPUT statement is used to prompt the user for data entry during program execution, allowing for interactive input. In contrast, the LET statement is used to assign a value to a variable directly within the program's code without user interaction. While INPUT gathers data from the user, LET simply assigns predefined values or calculations to variables. This distinction makes INPUT essential for interactive applications, whereas LET is fundamental for setting and manipulating variable values programmatically.
