How are prototypes categorized in terms of complexity?

Prototypes are categorized in terms of complexity and format because they serve various purposes throughout the design process. Prototypes can range from low-fidelity representations, such as paper sketches or wireframes, to high-fidelity digital simulations. This variability allows designers to choose a level of complexity that best meets the specific needs of the stage they are in, whether it's for initial brainstorming, user testing, or final validation. The use of different formats, including both digital and non-digital prototypes, enhances the flexibility of the design process and enables effective communication of ideas, functionalities, and user experiences to stakeholders and users. This categorization is essential for UX designers to create relevant and effective prototypes that align with project goals and user needs.
