A new technique for defining and measuring head shapes was developed and applied in the fabrication of a set of first generation plaster headforms. The design of a unique head measuring device is reported. The device is a clear polycarbonate hemisphere on which are mounted twenty-seven moveable mechanical probes. The hemisphere is placed over a subjects head, and the probes are moved to contact the head and thus define head shape. The probe data from a population of Army men were reduced statistically to yield generalized head shapes. The feasibility of combining this probe technique with classical anthropometric head measurements to yield generalized head shapes of various sizes was demonstrated. A set of first generation headforms was sculptured using specified probe data.
