Mockups and prototypes are used at various stages of the design process to represent and test ideas. They allow designers to gather user feedback through techniques like surveys, interviews, and usability testing to inform interface design and requirements definition. Low-fidelity prototypes using paper or basic digital tools help define requirements and gather early feedback, while high-fidelity digital prototypes are used for more rigorous usability testing.
