Which term is often the first step in rapid prototyping for user interface design, using simple paper sketches and models?

• A. Particle boards
• B. Natural fibres
• C. Paper-based rapid prototyping
• D. Mechanized production

Answer: (C)

In rapid prototyping for user interface design, the first step is to create simple, low-fidelity representations of the interface on paper. Paper-based rapid prototyping uses hand-drawn screens, sticky notes, or paper cutouts to sketch layouts, buttons, menus, and navigation paths, allowing quick exploration of how a user would move through the product. This approach is fast and inexpensive, so you can test ideas, revise flows, and gather feedback before committing to software development. Because changes can be made by re-drawing or rearranging sheets, it supports rapid iteration and collaboration with stakeholders, which speeds up finding a usable design early. The other terms don’t fit this context—they refer to materials or processes outside the domain of UI design prototyping.
