Digital Human Modeling in the User-Centered Design Process

The process of designing products has changed drastically over the past 20 years, with an increasing reliance on virtual processes such as computer-aided design (CAD) software. CAD software provides designers and engineers with tools that allow the production of virtual parts that are highly accurate in terms of geometric and visual representation. Automotive manufacturers, who bene™t from the ability to accurately model the thousands of parts that interact to produce an automobile, have embraced these powerful tools. The virtual automotive design process has reduced the need for physical mock-ups that were traditionally produced to support the engineering design process. A negative side effect of this is that the user testing opportunities that were afforded by the
