The tangible creation of artifacts, at various levels of resolution, for development and testing of ideas
Prototypes are essential for early and iterative concept testing by the design team, clients, and potential users.
Low-fidelity prototyping is common throughout early ideation processes in all design disciplines, appearing as concept sketches, storyboards, or sketch models.
A common method of low-fidelity prototyping in interface and software design is paper prototyping, with printed pages representing interface screens.
In graphic design, the “comp” serves as a low-fidelity prototype, presenting a mocked-up version of a proposed printed piece, usually for client review.
In industrial design, low-fidelity prototypes may be sketch models intended for iterative design review or as proof of concept models to test form and scale.
High-fidelity prototypes represent the appearance of the final product in look and feel and basic functionality, through interactive computer or physical models.
