Which term is a scale or full-size representation used to gain feedback from users?

• A. Part drawings
• B. Mock-ups
• C. Motion capture
• D. Physical modelling

Answer: (B)

Mock-ups are realist representations of a product built at scale or full size so designers can test how it will be used in real life. By letting users handle and interact with a model, you can observe ergonomics, usability, and overall feel, and gather concrete feedback to improve the design before committing to final production. This focused use of a physical or digital stand-in is why mock-ups are the go-to for user-centered testing.

Part drawings are for communicating dimensions and manufacturing details, not for testing with users. Motion capture records how people move, used for analyzing movement or animation, not for evaluating a finished product’s form or usability. Physical modelling creates a tangible version for exploring form or structure, which can support early ideas, but the term that specifically means a scale or full-size model used to gain user feedback is mock-up.
