Interface Prototyping is the process of creating a preliminary version of a user interface to visualize and test its design and functionality. This can involve sketches, wireframes, or interactive models that help designers and stakeholders understand how users will interact with a product. Prototyping allows for early feedback, which can lead to improvements before the final product is developed. By using prototyping tools like Figma or Adobe XD, designers can simulate user experiences and identify potential issues. This iterative approach not only enhances usability but also saves time and resources by addressing design flaws early in the development process.
