Which term denotes a rapid prototyping approach used to design and test interfaces in user-centered design?

• A. Paper-based rapid prototyping
• B. Multi task robots
• C. Particle boards
• D. One-off production

Answer: (A)

In user-centered design, rapid prototyping of interfaces relies on quick, flexible representations to test how users will actually interact with the product. Paper-based rapid prototyping uses simple sketches of screens, buttons, and navigation on paper. This lets designers simulate the flow and layout of the interface, gather real user feedback, and make changes on the spot without writing any code. It’s fast, inexpensive, and highly iterative, so you can explore different ideas for where to place controls, what labels to use, and how the user will move from one screen to another, all before committing to a digital build.

The other terms don’t fit this goal: multi task robots describe a kind of device or system, not a prototyping method for interfaces; particle boards are a material used in construction, not an interface-design process; one-off production refers to producing a single item rather than iterative design testing.
