Abstract
After we have all the tools and resources we need, the next step is to create our first prototype or mock-up. To do this we need some representation of an individual or individuals around which to design and build it. We call these individuals "cases". A case can have three forms: (1) a list of measurements of an individual, (2) a threedimensional (3D) or four-dimensional (4D) model of an individual, or (3) the actual individual. The actual individual is sometimes called a fit model or a live model. This begins with the selection of a case to represent the first size called the base size. Selecting this case effectively gets the design centered on the area of the Target Population (TP) that has the greatest concentration of people. Additional cases are selected to evaluate the potential range of fit. Cases are portrayed in two ways for prototyping products: (1) physical manikins and people or (2) digital manikins. This chapter discusses how to select, model, and use a small number of cases to design, modify, or redesign a product and produce a mock-up or prototype.
