What does the term "prototyping" mean in digital design?

In digital design, the term "prototyping" refers specifically to the process of creating an interactive model that simulates user interaction. This approach allows designers to visualize and test the functionality of their designs before committing to more extensive development. By creating prototypes, designers can explore how users might navigate through an interface, how interactive elements will function, and whether the overall user experience aligns with their objectives.

Prototyping is crucial because it helps identify usability issues early in the design process, allowing for iterations and adjustments based on user feedback. This not only enhances the design but also saves time and resources in the long run, as potential problems can be resolved before actual implementation.

In contrast, options like creating static images or designing layouts without interaction do not encapsulate the full essence of prototyping, which relies heavily on interactivity and user feedback. Additionally, developing software from scratch involves a more extensive process than prototyping, which focuses on early-stage design validation rather than the final product development.
