Anthropometric measurements were made of the hands of 32 subjects. Data from this survey were used in the design of a graphic model of the male human hand. The model was created in the computer-aided design (CAD) package CATIA and reproduced any desired overall hand size. It was made up of 24 solid segments with 23 degrees of freedom at 17 moveable joints. Spans and grasping sizes of the model hand were examined. The representation of the model appeared realistic in several postures, but the model was found to allow some motions which would be impossible for an actual hand. The model could be used to help a designer visualize hand-held products and controls in use.
