Which term refers to the creation of a smaller or larger tangible version of an object that can be physically interacted with?

• A. Mock-ups
• B. Laminated object manufacturing (LOM)
• C. Physical modelling
• D. Motion capture

Answer: (C)

Creating a smaller or larger tangible version that you can pick up, test, and examine is physical modelling. This approach lets designers explore form, size, ergonomics, and how a product would actually feel in use, whether scaled down or up to final size. It supports hands-on interaction to reveal how the object behaves, fits in the hand, or sits in a space, enabling quick iterations before committing to production. A mock-up is a tangible representation used mainly to study appearance or layout and isn’t always focused on how the product will function in real use. Laminated object manufacturing is a specific rapid‑prototyping method for building objects from laminated sheets, not the general idea of creating interactive physical versions. Motion capture, by contrast, records movement for analysis or animation, not for producing a physical model to interact with.
