Which of the following best describes a low-fidelity prototype?

A low-fidelity prototype is best described as a simplified and basic representation of a design idea. This type of prototype often focuses on the overall layout and flow of the design rather than intricate details or high levels of interactivity. Low-fidelity prototypes can be created quickly and are typically made using simple materials like paper or basic digital tools, allowing designers to test concepts and gather feedback early in the design process.

By using a low-fidelity prototype, designers can explore ideas and iterate on them without the time and resource constraints that come with developing more detailed models. This allows for effective communication of ideas and facilitates user testing to understand user interactions at a more fundamental level. In contrast, other options like an interactive digital model, a high-detail visual representation, or a fully functional version of the app imply a higher level of complexity and detail that characterizes high-fidelity prototypes rather than low-fidelity ones.
