What characterizes a Hi-Fi prototype in UX?

A high-fidelity (Hi-Fi) prototype in user experience design is characterized by its close resemblance to the final product. This means that the prototype is designed to reflect the final visual and functional aspects of the product as accurately as possible. Hi-Fi prototypes include not just detailed visuals, such as color schemes and typography, but also interactive elements that allow users to experience and test the design as they would in the actual product. This level of detail helps to gather more precise feedback from users regarding both the usability and aesthetic appeal of the product.

In contrast, other options represent different stages or styles of prototyping. Low-fidelity prototypes focus more on basic concepts and layouts without detailed visual components, textual representations denote descriptive aspects of a design without visuals, and sketches are often used in initial brainstorming sessions to convey ideas quickly without the need for high-quality rendering. Therefore, the selection of the correct response reflects a clear understanding of the role Hi-Fi prototypes play in the design process.
