GRAPHICS: LABELS AND DECALS

Graphics are used on both low- and high-fidelity models. They are an important aspect of user testing with interactive products. Screens and buttons are labelled so as to test various scenarios of use as well as to communicate functional features. Logos can also add a final touch of realism to models.

The simplest approach is to use the inkjet printer and plain paper to print out a label or graphic. This is certainly acceptable for low-fidelity prototyping. A vector-based illustration program (Adobe Illustrator® or CorelDRAW®) is perfect for laying out the artwork. For low-fidelity prototyping this may be simple line work (see tutorial, page 163), while for higher-fidelity prototyping the artwork can be more advanced ...
