Abstract
Developments in laser digitizing technology now make it possible to capture very accurate 3D images of the surface of the human body in less than 20 seconds. Applications for the images range from animation of movie characters to the design and visualization of clothing and individual equipment (CIE). In this paper we focus on modeling the user/equipment interface. Defining the relative geometry between user and equipment provides a better understanding of equipment performance, and can make the design cycle more efficient. Computer-aided fit testing (CAFT) is the application of graphical and statistical techniques to visualize and quantify the human/equipment interface in virtual space. In short, CAFT looks to measure the relative geometry between a user and his or her equipment. The design cycle changes with the introducing CAFT; now some evaluation may be done in the CAD environment prior to prototyping. CAFT may be applied in two general ways: (1) to aid in the creation of new equipment designs and (2) to evaluate current designs for compliance to performance specifications. We demonstrate the application of CAFT with two examples. First, we show how a prototype helmet may be evaluated for fit, and second we demonstrate how CAFT may be used to measure body armor coverage.
