Mock-ups are used by designers mainly to acquire feedback from users
about designs and design ideas early in the design process. Mock-ups are
'very early prototypes' made of cardboard or otherwise low-fidelity
materials. The user, aided by the designer, may test the mock-up
(imagining that it works) and thus provide valuable feedback about
functionality/usability/understanding of the basic design idea/etc. - interaction-design
