Houde and Hill (1997) propose a model for classifying prototypes according to their purpose and the design questions they answer. Since this model was created for user interaction design, it has never been applied to physical prototypes on a large scale or to a progression of prototypes through the product development cycle. Ten physical prototypes from an MIT mechanical engineering senior capstone design course are evaluated according to the Houde and Hill (1997) model.
