Affordance

Affordance refers to the concept that helps users understand what actions they can take without needing pictures, labels, or instructions.

A clear example of affordances is found in buttons; users recognize that buttons can be pressed because they look similar to the buttons they encounter and use in everyday life. This means that a control functions so that it matches its appearance. Good accessibility promotes intuitive interaction.

Affordances provide hints about how an object can be used to perform a specific action. For example, the slots on a vending machine are affordances, indicating that you can insert something, such as a coin, to make a purchase.
