Abstract

The objective of this research is to develop a process which will analyze and group human faces, concentrating on the oxygen mask seal area, into a minimum number of generic yet distinct face types. The shape and size, or form, of the face is described by bending energies. This bending energy provides the features for the grouping of similar face types, while distinguishing representatives for each cluster. The face tariffs are the percentage of faces grouped under a representative face. The representative faces are then transformed Into three-dimensional solids using computer-aided design. A rapid prototype creates the solids or plugs from which MBU-5P masks are made and tested. The two major outcomes of this research are a formal morphological method which allows the comparison between multiple faces, and a process to transform anthropomorphic surfaces into a prototype mask mold.
