DENIM: an informal tool for early stage web site design.

DENIM is a system that helps web site designers in the early stages of design. DENIM supports sketching input; allows design at different refinement levels--site map, storyboard, and individual page; and unifies the levels through zooming. The design of DENIM was informed by a study of web site design practice, in which we observed that web site designers design sites at the levels of refinement mentioned above and that designers sketch at all levels during the early stages of design.
