What is the main function and purpose of an icon in a user interface?

An icon in the user interface serves as a visual representation of an action, object, or state, facilitating user perception and navigation. It helps quickly understand the purpose of a button or element without the need to read text.

Main functions of an icon:

• Simplifying the interface through compact visual representation.
• Enhancing user convenience and interaction speed with the application.
• Creating recognition and aesthetic appeal.

For example, a shopping cart icon usually indicates the action "add to cart" or "view cart" in a shopping application.
